This free TX-ZAF guide develops the decisions behind South African tax computations: residence, income recognition, deductions, company adjustments, capital gains, VAT and compliance. Twenty original questions combine multiple-choice decisions with constructed responses; sixty concepts explain mechanisms, worked applications and common errors. It follows the June 2026, December 2026 and June 2027 syllabus current on 16 October 2026, using its 30 September 2025 legislative cutoff. Numerical rules supplied in exercises are explicit practice assumptions, not verified examinable tax tables. Source s2 establishes syllabus relevance, rather than verifying every technical explanation. This representative preview is not a full mock, and later qualification versions are outside its scope.
What this guide covers
Practise South African tax computations with 20 original questions and 60 focused TX-ZAF concepts.
The South African tax system
1. Tax functions and economic incidence
Taxation raises revenue for public expenditure, redistributes resources and can influence consumption, investment and other economic behaviour. Direct taxes attach to a taxpayer's income or taxable capacity; indirect taxes commonly attach to transactions or consumption. Distinguish legal incidence, identifying who must account for tax, from economic incidence, identifying who ultimately bears its cost. Prices, wages and market conditions can shift that economic burden. This distinction explains why a VAT vendor can owe SARS while customers bear much of the charge through prices, and why collection responsibility alone does not classify a tax.
Worked example: A shop sells taxable goods and accounts for VAT to SARS. Customers pay VAT within the selling price. The shop performs the collection function, while the consumption tax generally increases the customers' cost of buying those goods.
Common mistake: Assuming the person submitting a tax return necessarily bears the entire economic burden confuses collection responsibility with economic incidence.

2. Legislation, judgments and treaty interaction
Tax analysis begins with applicable legislation, including its commencement provisions, and relevant judicial interpretation. Regulations and other delegated instruments operate within their lawful authority. SARS guides explain administration but do not themselves amend an Act. Double taxation agreements coordinate taxing rights between jurisdictions and may modify domestic outcomes when applicable. Domestic residence, source and exemptions still need identification before considering treaty interaction. TX-ZAF requires appreciation of that interaction, while detailed knowledge of specific treaties is excluded. Always separate the authority of a source from how convenient or recent its explanation appears.
Worked example: An older explanatory guide describes an exemption more broadly than an amended statutory provision. An adviser identifies the amendment's effective date, applies the enacted wording to the transaction and records the guide's inconsistency rather than treating publication as law.
Common mistake: Treating every SARS publication as legislation obscures differences between binding rules, judicial interpretation and material explaining administrative practice.

3. Tax planning, evasion and the GAAR
Tax planning uses legally available choices and reliefs with accurate disclosure. Evasion involves unlawful conduct, such as concealing income or falsifying deductions. Avoidance arrangements require a further distinction: formal compliance does not necessarily protect an arrangement from the General Anti-Avoidance Rule. Its statutory conditions address impermissible arrangements, including relevant purpose and abnormality or misuse considerations. A genuine transaction can produce tax savings without automatically satisfying those conditions. Apply the rule to the arrangement's facts and legal requirements rather than assuming either that all tax reduction is improper or that documentary form guarantees effectiveness.
Worked example: A trader claims a qualifying capital allowance on equipment genuinely bought for production. Another trader invents an equipment invoice. The first uses statutory relief; the second misrepresents facts. A contrived multi-step arrangement would require a separate GAAR analysis.
Common mistake: Calling every tax-saving transaction evasion prevents proper distinction between legitimate relief, potentially impermissible avoidance and dishonest factual misstatement.

4. Returns, assessments and payment credits
A return reports the taxpayer's information and calculations; an assessment determines the liability under the applicable assessment system. Withholding and provisional payments are generally payments towards the eventual normal-tax liability rather than deductions from taxable income. Reconcile income, adjustments, tax liability and payment credits separately. An assessment can produce a balance payable or refundable, and an additional assessment may alter an earlier result where legally permitted. Filing a return does not establish that every reported claim is accepted, while receiving an assessment does not remove the need to check its figures and allocations.
Worked example: A taxpayer's annual normal tax is R92,000, with PAYE of R70,000 and provisional payments of R15,000. The reconciliation shows R7,000 payable. Neither payment amount reduces the taxable income on which the R92,000 liability was calculated.
Common mistake: Subtracting PAYE from taxable income understates the tax base and then risks giving the taxpayer a second credit for the same payment.
Official syllabus reference: [2]
5. Employer PAYE responsibilities
Employees' tax requires employers to identify remuneration, calculate withholding under the applicable tables or directives, deduct it and account for it to SARS. Taxable benefits and allowances may affect remuneration even when no corresponding cash reaches the employee. Employers must also maintain payroll evidence and reconcile reported remuneration and deductions with amounts paid. PAYE withholding is distinct from determining the employee's final annual liability. A correct salary payment does not prove correct tax reporting, particularly where benefits, variable remuneration or employment commencement change the payroll calculation during the year.
Worked example: An employer pays a cash salary and provides a taxable company-car benefit. Payroll includes the prescribed benefit component when calculating withholding and records the benefit separately, allowing the annual employee certificate to reconcile remuneration with the employer's submitted figures.
Common mistake: Restricting payroll tax calculations to cash salary can omit taxable non-cash remuneration and create mismatches in employer reconciliations.
Official syllabus reference: [2]
6. Provisional tax and late-payment interest
Provisional tax is a collection mechanism for normal tax, using estimates and payments during the assessment cycle. It is not an additional tax on the same income. Distinguish the liability estimate, instalments already paid and the final assessed balance. Filing an estimate and paying the corresponding amount are separate obligations, each with applicable timing rules. Late-payment interest compensates for overdue tax and should be calculated using the prescribed base, rate and period. Penalties may arise separately. Do not invent a single deadline or interest method for every taxpayer and tax type.
Worked example: Under an exercise's simple-interest assumptions, R30,000 overdue for 60 days at 9% annually produces R30,000 × 9% × 60/365 = R443.84 interest. The calculation is separate from any penalty and from the taxpayer's final annual tax reconciliation.
Common mistake: Treating provisional tax as an expense or an extra tax duplicates the liability instead of recognising a payment towards normal tax.
Official syllabus reference: [2]
7. Records, filing dates and claim evidence
Tax records connect reported figures to transactions and legal entitlement. Useful evidence includes invoices, contracts, bank records, payroll data, asset registers and calculations supporting exemptions or deductions. Different obligations can have different submission dates, retention periods and triggering events; an assessment dispute or investigation may also affect retention requirements. Build a transaction-to-return trail rather than relying on bank totals alone. A bank payment establishes that money moved, but may not establish business purpose, tax timing or entitlement to input VAT. Apply the relevant deadline and retention rule to the particular obligation.
Worked example: A consultant claims equipment relief using the purchase invoice, proof of payment, date brought into use and business-use records. Keeping only the bank entry would leave the asset category and period of qualifying use insufficiently supported for the calculation.
Common mistake: Assuming a bank statement proves every deduction ignores the separate need to establish purpose, timing, classification and statutory eligibility.
Official syllabus reference: [2]
8. Objection and appeal versus payment suspension
An objection challenges an assessment or appealable decision through the prescribed process, supported by identifiable grounds and evidence. If the objection is disallowed, an appeal may be available under the applicable rules. These procedures address the correctness of the decision. Payment suspension addresses whether collection should pause while a dispute is resolved and is a separate matter. Do not assume that lodging an objection automatically suspends payment or interest. Check the assessment, identify the disputed adjustment, establish the applicable deadline and distinguish the requested substantive correction from any request concerning collection.
Worked example: SARS disallows an expense because its invoice was missing. The taxpayer submits a supported objection identifying the adjustment and attaching the invoice and business-purpose evidence. If collection relief is needed, the taxpayer addresses payment suspension separately rather than assuming the objection achieves it.
Common mistake: Writing that an assessment is unfair without identifying the disputed adjustment and supporting grounds weakens an otherwise potentially valid objection.
Official syllabus reference: [2]
9. Verification, audit and information powers
SARS can examine returns and obtain information through powers established by tax administration legislation. Verification commonly checks particular reported information, while an audit can examine the taxpayer's affairs more extensively. Information requests, access, search and seizure have legal requirements; they are not interchangeable procedures with unlimited scope. Identify what power is being exercised, what information is requested and the applicable response requirements. Reconcile supplied records to the return so explanations remain consistent. An information request does not itself prove wrongdoing, but an unsupported response can leave an adjustment unresolved or expose further compliance issues.
Worked example: A VAT vendor receives a request for invoices supporting a specific input-tax claim. It provides the relevant invoices, a schedule linking them to the return and explanations of any differences, rather than sending an unexplained export of its entire accounting system.
Common mistake: Assuming verification establishes evasion confuses an administrative checking process with a concluded finding about the taxpayer's conduct or liability.
Official syllabus reference: [2]
10. Tax-practitioner registration and professional conduct
A person providing covered tax advice or return services for reward generally needs registration with SARS and a recognised controlling body, subject to statutory exclusions. Registration creates professional obligations rather than transferring the client's liability to the practitioner. Accurate representations, confidentiality, competence and appropriate handling of conflicts support reliable tax work. Distinguish a computational error from deliberate misconduct, and identify the relevant reporting route where unprofessional conduct arises. Tax non-compliance may also attract administrative penalties, understatement penalties or criminal consequences under different conditions; these consequences should not be treated as interchangeable or automatically cumulative.
Worked example: A practitioner discovers that a client supplied a fabricated invoice. The practitioner explains that it cannot support the deduction, seeks correction and considers the applicable professional reporting obligations. Simply retaining the document does not make the proposed return accurate or defensible.
Common mistake: Believing practitioner registration guarantees every return is correct overlooks the continuing duties of both the practitioner and the taxpayer.

Income tax liabilities
11. Residence through presence and subsequent continuous absence
Ordinary residence considers where an individual's usual home is established. An individual who is not ordinarily resident may nevertheless become resident through physical presence. That alternative requires sufficient days in the current assessment year, sufficient days in each of the five preceding assessment years, and sufficient aggregate days across those preceding years. Passing only the current-year condition is insufficient. For someone resident through physical presence, the prescribed continuous absence can terminate that residence retrospectively from the first day of absence. Use the applicable examinable day counts and consider any relevant treaty override separately.
Worked example: Assume exercise requirements of 92 current-year days, 92 in each preceding year, 916 aggregate preceding days and a 330-day absence trigger. Leo has 100 current-year days and 200 in each preceding year: he qualifies. His subsequent 330-day continuous absence ends that residence from departure.
Common mistake: Counting only this year's visits misses the preceding-year tests; treating departure alone as immediate cessation misses the continuous-absence condition.
Official syllabus reference: [2]
12. Employment versus independent trade
Employment classification depends on statutory rules and the substance of the engagement, including control, supervision, integration, working arrangements and commercial risk. A contract's description as consulting does not settle the result. Classification affects employees' tax obligations and the deductions available to the worker. An independent trader ordinarily earns business receipts and tests expenses under trade deduction rules; an employee faces employment-specific restrictions. Examine the relevant relationship as a whole and distinguish tax classification from invoice formatting. A worker issuing monthly invoices can still be within an employment-related withholding regime where the governing tests require it.
Worked example: Two designers invoice monthly. One works fixed hours under a client's supervision using its systems; the other sets her own methods, serves several clients and bears rework costs. Those substantive differences matter more than the shared invoice label.
Common mistake: Assuming every person called a contractor has unrestricted business deductions substitutes contractual wording for the statutory and factual classification tests.
Official syllabus reference: [2]
13. Employment accrual and the variable-remuneration timing exception
Employment income generally requires consideration of both receipt and accrual: an unconditional entitlement can matter even when payment follows later. However, the section 7B timing rule changes the treatment of qualifying variable remuneration, including employment bonuses. Such remuneration is generally recognised when paid, rather than when the employee first becomes unconditionally entitled to it. Identify the payment category before applying the general accrual principle. Distinguish an ordinary salary debt from a qualifying bonus, establish the actual payment date, and allocate each amount to its correct assessment year without counting it twice.
Worked example: Assume an assessment year ends on 28 February. Ayanda earns ordinary February salary of R30,000, paid in March, and becomes entitled in February to a qualifying section 7B bonus of R18,000, also paid in March. Salary belongs to the ending year; the bonus belongs to the following year.
Common mistake: An unconditional bonus entitlement does not override the payment-based timing rule for qualifying variable remuneration.
Official syllabus reference: [2]
14. Travel allowances and business-kilometre evidence
A travel allowance is not automatically exempt merely because the employee drives for work. The final assessment considers the allowance and the deduction or reduction permitted for qualifying business travel. A reliable logbook separates business kilometres from private travel, including ordinary commuting where treated as private. The applicable method determines how actual or prescribed costs are used, with any cost limits and apportionments. Payroll inclusion and final-assessment treatment can differ. Distinguish an allowance from reimbursement and from the taxable benefit of using an employer-owned vehicle; each has its own mechanism.
Worked example: An employee records 24,000 total kilometres and 9,000 qualifying business kilometres. Under an exercise allowing R80,000 vehicle costs apportioned by distance, the business amount is R80,000 × 9,000/24,000 = R30,000, subject to any stated allowance restriction.
Common mistake: Treating all travel from home as business travel can overstate the qualifying distance and distort the allowance calculation.
Official syllabus reference: [2]
15. Trade deductions and pre-trade expenditure
The general deduction analysis examines whether expenditure was actually incurred in producing income, relates to carrying on trade and is not capital in nature, together with applicable prohibitions. Private expenditure does not qualify merely because a business account paid it. Pre-trade expenditure needs its specific relief route because ordinary trade conditions may not yet be met when it arises. Establish the trade's commencement, the expenditure's character and any restriction on utilisation. A durable asset may obtain a capital allowance rather than an immediate expense deduction. Employment deductions remain subject to separate restrictions.
Worked example: Before opening a design practice, a taxpayer pays qualifying preparatory advertising costs and buys a computer. The advertising is tested under pre-trade relief, while the computer is classified as capital expenditure and considered under the relevant allowance provisions.
Common mistake: Deducting every start-up payment immediately ignores the distinction between qualifying pre-trade expenses, capital assets and expenditure lacking a trade connection.
Official syllabus reference: [2]
16. Matching asset categories to capital-allowance mechanisms
A capital allowance depends on the statutory asset category and its qualifying use, rather than the depreciation policy used in the accounts. Qualifying manufacturing machinery may receive accelerated deductions when brought into use, while a qualifying manufacturing building follows a separate cost-based annual allowance. Establish ownership, qualifying expenditure, commencement of use and the conditions attached to the particular category. Apply the supplied rate and any required apportionment only after qualification is established. Accounting depreciation is then replaced by the relevant tax allowance; it is not an additional deduction alongside that allowance.
Worked example: Assume qualifying new manufacturing machinery receives 40% in its first year and a qualifying manufacturing building receives 5%, with no apportionment. Machinery costing R600,000 yields R240,000; a building costing R900,000 yields R45,000. The combined deduction is R285,000, replacing the related accounting depreciation.
Common mistake: Applying the machinery's accelerated percentage to a building ignores the separate asset category and overstates the deduction.
Official syllabus reference: [2]
17. Recoupment and capital gain on disposal
Disposal of an asset that received tax allowances can create an ordinary-income recoupment as well as a capital gain. The recoupment reverses qualifying deductions recovered through proceeds, subject to applicable limits. The capital-gains computation coordinates proceeds and base cost to prevent the same amount being taxed twice. Start with original qualifying cost, allowances previously granted, proceeds and any special disposal rule. Do not compare proceeds solely with accounting carrying value. A disposal below tax value may raise a different deduction question, whose conditions must be established rather than assumed from an accounting loss.
Worked example: Assume equipment cost R100,000, received R60,000 allowances and sells for R120,000. Under a simplified coordinated treatment, R60,000 is recouped and the R20,000 excess above original cost is considered separately as a capital gain.
Common mistake: Taxing the full excess over tax value as both recoupment and capital gain duplicates income already addressed by the recoupment rules.
Official syllabus reference: [2]
18. Determining whether an individual's sideline loss is ring-fenced
Individual loss ring-fencing requires a structured eligibility test. First assess whether income before the relevant loss reaches the applicable top-bracket gateway. Then examine whether the trade meets the repeated-loss condition over the specified period or falls within a listed suspect activity. Where the restriction is triggered, consider whether objective evidence establishes the required reasonable prospect of taxable income within a reasonable period, subject to any statutory restriction on that escape. A ring-fenced loss cannot shelter unrelated salary; it is carried forward for permitted use against income from the same trade.
Worked example: Assume an exercise gateway of R1 million and a repeated-loss trigger of three loss years in five. Mira has R1.2 million salary and a R60,000 sideline loss, its third loss in five years. With no reasonable prospect of profit and no escape available, salary remains R1.2 million.
Common mistake: A genuine trade does not automatically permit its loss to offset salary when the individual ring-fencing conditions are satisfied.
Official syllabus reference: [2]
19. Partnership profit allocation and limited partners
A partnership generally provides a vehicle for earning and allocating income rather than being taxed as a separate company on its profits. Compute the partnership's tax-adjusted result and allocate the relevant income and deductions to partners according to their entitlements. Drawings are withdrawals of capital or profit, not automatically deductible salaries. Partner-specific circumstances then affect each partner's own computation. Limited partners require attention to restrictions on deductible losses relative to their qualifying exposure. An allocation agreement does not override statutory restrictions or turn a non-deductible partnership expense into deductible expenditure for the partners.
Worked example: Two partners share a tax-adjusted profit of R360,000 in a 60:40 ratio. Their starting allocations are R216,000 and R144,000. Different cash drawings during the year do not by themselves change those profit entitlements or create partnership deductions.
Common mistake: Taxing partners only on drawings confuses cash withdrawals with the allocation of partnership income earned during the assessment period.
Official syllabus reference: [2]
20. Separating microbusiness entry turnover from the taxable base
Qualifying turnover determines whether a microbusiness meets the turnover requirement for entry into the regime. Taxable turnover determines the amount to which the regime's tax schedule applies. These measures need not contain identical receipts: capital receipts are excluded when measuring qualifying turnover, while the taxable-turnover calculation can include a prescribed portion of proceeds from qualifying business capital assets. Borrowed money is financing rather than business turnover. Classify each receipt separately for both measures, then check the remaining eligibility conditions before calculating tax. Passing the turnover test alone does not establish complete eligibility.
Worked example: An individual trader receives R300,000 cash sales, R80,000 for equipment used wholly in business and a R50,000 loan. Assume taxable turnover includes 50% of these equipment proceeds and all eligibility conditions hold. Qualifying turnover is R300,000; taxable turnover is R340,000. The loan enters neither measure.
Common mistake: Using the eligibility turnover unchanged as taxable turnover overlooks capital proceeds that the tax-base rules partly include.
Official syllabus reference: [2]
21. Arm's-length transfer-pricing adjustments
Transfer-pricing rules can adjust taxable results where an affected cross-border relationship or arrangement uses terms that differ from arm's-length terms and produces the relevant tax consequence. Analyse the transaction's actual functions, assets, risks and commercial conditions before choosing a comparable price or margin. Related ownership alone does not establish the adjustment amount. A domestic accounting invoice is evidence of what was charged, not proof that the charge is arm's length. TX-ZAF requires recognition and application of the rules; complex specialist financial instruments and detailed treaty analysis remain outside the supplied scope.
Worked example: Assume an affected trader buys stock from a connected foreign supplier for R140,000, while a reliable comparable supports R110,000 under identical conditions. If the rules require an arm's-length adjustment, the R30,000 excess cannot simply remain an unrestricted tax deduction.
Common mistake: Using an unrelated business's headline price without comparing contractual conditions, functions and risks can produce an unreliable transfer-pricing adjustment.
Official syllabus reference: [2]
22. Foreign-exchange gains and losses
Foreign-currency transactions require translation at the rates and dates specified by the applicable tax provisions. Distinguish initial recognition, year-end remeasurement and settlement. An exchange difference arises because the rand value of a monetary right or obligation changes; it is separate from the underlying sale or purchase. Tax treatment may depend on the taxpayer and the item being within the relevant exchange provisions. Do not automatically copy an accounting reserve or wait for cash settlement when the tax rule requires earlier recognition. Keep currency units and the quotation direction explicit throughout the calculation.
Worked example: Assume a qualifying US$10,000 trade receivable is recognised at R18 per dollar and remeasured at R19 under the exercise's year-end rule. Its rand value rises from R180,000 to R190,000, producing a R10,000 exchange gain before settlement.
Common mistake: Treating a stronger dollar as a loss on a dollar receivable reverses the economic direction of the taxpayer's currency exposure.
Official syllabus reference: [2]
23. Rental income, repairs and improvements
Property income includes amounts received or accrued from letting, with deductions tested against the income-producing activity. Repairs generally restore an existing asset, while improvements create or enhance an enduring asset and require capital analysis. Interest, levies and other expenditure need an appropriate rental connection and private-use apportionment where relevant. A refundable security deposit is distinguished from an amount beneficially received as rental income. A rental loss may also need the individual loss restrictions considered. Classification turns on the work's substance; describing a structural extension as maintenance does not establish an immediate deduction.
Worked example: A landlord replaces broken roof tiles and separately adds a new room. The tile work is examined as restoration, while the extension is analysed as capital improvement. If the property also serves private purposes, the relevant expenses require supportable apportionment.
Common mistake: Deducting all building expenditure as repairs ignores the difference between restoring existing functionality and creating additional enduring value.
Official syllabus reference: [2]
24. Interest, dividends and withholding layers
Investment receipts require classification before applying relief. Local interest may qualify for an individual exemption, while ordinary local dividends can be exempt from normal tax yet remain subject to a separate dividends-tax mechanism. Foreign dividends require their own exemption analysis, including any qualifying full exemption or partial exemption. Withholding is a collection or final-tax mechanism defined for the relevant payment; it is not automatically a normal-tax deduction. Identify the recipient, source and payment category, then apply only the available relief. The supplied syllabus limits the dividends-tax exemptions examined, so avoid importing an unrestricted catalogue.
Worked example: An individual receives local interest and an ordinary local dividend. The interest enters the normal-tax computation after its applicable exemption. The dividend's normal-tax exemption is considered separately from any dividends tax withheld, allowing the two tax mechanisms to remain visible.
Common mistake: Assuming normal-tax exemption means no possible tax on a dividend overlooks the separate liability and collection rules for dividends tax.
Official syllabus reference: [2]
25. Retirement and donation deduction sequencing
Retirement contributions and qualifying donations obtain relief through different deduction provisions with their own eligibility, ceilings and carry-forward mechanisms. Establish the retirement deduction using its specified income base and limits, then calculate the donation ceiling using the correctly ordered taxable-income base. A payment exceeding a current deduction limit does not necessarily disappear; identify the applicable carry-forward treatment separately for each relief. Donation receipts and the recipient's qualifying status matter. Neither relief is a direct reduction of tax at the payment amount. Excluded retirement lump-sum taxation should not be imported into ordinary contribution calculations.
Worked example: Using assumed limits, R500,000 before deductions is reduced by a permitted R100,000 retirement deduction. A donation ceiling of 10% of the remaining R400,000 permits R40,000 relief, even if the taxpayer actually donated R55,000 during the year.
Common mistake: Applying every percentage ceiling to gross salary ignores the distinct statutory bases and can overstate several deductions simultaneously.
Official syllabus reference: [2]
26. Progressive tax, rebates and medical credits
An individual computation moves from taxable income to tax using the applicable progressive bands, then applies rebates and qualifying medical tax credits. A marginal rate applies to the slice within its band, not necessarily to all taxable income. Medical scheme fee credits and any additional medical expense credit have distinct eligibility and calculation rules; use the supplied amounts and facts rather than treating all medical payments as deductible income expenses. PAYE and provisional payments are credited after determining liability. Maintaining these stages explains why a deduction, a tax credit and a payment of the same amount have different effects.
Worked example: Under an assumed 30% marginal rate, a R1,000 income deduction reduces tax by R300. A qualifying R1,000 tax credit reduces tax by R1,000, subject to its rules. PAYE of R1,000 instead settles R1,000 of the resulting annual liability.
Common mistake: Subtracting medical credits before applying tax bands treats a tax reduction as an income deduction and usually understates its intended effect.

Company tax liabilities including dividends tax for in-specie dividends
27. Company residence and effective management
Company residence is determined using the statutory incorporation-related and place-of-effective-management tests, subject to applicable treaty treatment. Effective management examines where key management and commercial decisions necessary for the business are made in substance. A registered address, bank account or meeting label does not alone settle the question. Residence establishes the starting scope of company taxation, while exemptions and specific charging provisions still require separate application. The TX-ZAF scope excludes detailed foreign-company trading and controlled foreign company rules, so those regimes should not be used to replace the basic resident-company analysis.
Worked example: A company has an overseas administrative address, but its substantive senior decision-making occurs in South Africa. An adviser examines the effective-management facts and incorporation position instead of assuming that the foreign address alone establishes non-residence for South African tax purposes.
Common mistake: Equating the location of bookkeeping with effective management overlooks the substantive location of the company's key management and commercial decisions.
Official syllabus reference: [2]
28. Testing small business corporation ownership and receipts
Small business corporation status depends on several concurrent conditions, rather than size alone. Examine whether shareholders are natural persons throughout the relevant period, whether their other equity interests fall within permitted exceptions, and whether gross income stays within the applicable ceiling. Test investment income and personal-service receipts against the relevant restriction, including the rules governing a personal-service business and any employee-based exception. A corporate shareholder can therefore prevent qualification even where turnover is modest. Record the actual ownership and receipt facts supporting each conclusion before applying the preferential tax schedule.
Worked example: Assume a R3 million gross-income ceiling and a 20% restricted-receipts limit. Oak has R2 million gross income, 5% investment receipts, no personal-service receipts and only natural-person shareholders without outside equity interests. It qualifies. Otherwise identical Pine has a corporate shareholder and therefore fails.
Common mistake: Low gross income cannot cure a failure of the shareholder condition; each qualification requirement must be satisfied.
Official syllabus reference: [2]
29. Comparing turnover tax with tax on business profit
A turnover-based regime taxes its defined receipts base without providing the ordinary deduction of operating expenses. Ordinary company tax instead starts from taxable profit, allowing qualifying expenditure and tax allowances. Consequently, a low-margin business can pay more under turnover tax even when its headline percentage is smaller. Compare liabilities using consistent sales assumptions and separately calculated tax bases. Confirm eligibility, election requirements and the consequences of entering or leaving the regime before recommending it. Administrative simplicity may influence the decision, but it does not establish which regime produces the lower liability.
Worked example: Assume an eligible company can choose either illustrative schedule: 3% of taxable turnover or 27% of taxable profit. Sales are R800,000 and deductible expenses R720,000, with no other adjustments. Turnover tax is R24,000; profit tax is R21,600. Ordinary profit taxation saves R2,400.
Common mistake: Comparing percentages alone ignores their different bases; a smaller turnover-tax rate can still produce the larger liability.
Official syllabus reference: [2]
30. Share repurchases and contributed tax capital
A company's purchase of its own shares requires analysis of the payment's legal tax character. Consideration may include a dividend component and a return of contributed tax capital where the statutory requirements are met. Accounting share capital and contributed tax capital are not automatically identical. The shareholder's disposal consequences must also be coordinated with dividend treatment to avoid assuming that the entire payment is either capital proceeds or deductible expenditure. At TX-ZAF level, focus on recognising this distinction and identifying the relevant amounts rather than importing specialist corporate restructuring regimes outside the syllabus.
Worked example: Assume a valid repurchase payment of R100,000 contains R30,000 of properly allocated contributed tax capital and R70,000 treated as a dividend under the supplied facts. The components require separate tax analysis rather than treating the entire payment as an operating expense.
Common mistake: Treating every repurchase payment as a deductible company cost confuses a distribution to owners with expenditure incurred to produce trading income.
Official syllabus reference: [2]
31. Gross income versus accounting revenue
A company identifies gross income using tax receipt and accrual principles rather than adopting accounting revenue unchanged. Consider whether amounts are received beneficially or accrued unconditionally, whether they are capital in nature and whether a specific inclusion applies. Loan proceeds generally represent financing rather than revenue, while a taxable recoupment may enter the tax computation despite a different accounting presentation. Exempt amounts must also be removed where included in accounting profit. Reconciliation therefore requires identifying both timing and character differences, rather than adjusting only expenses or assuming all bank deposits are taxable sales.
Worked example: A company receives customer fees, a bank loan and proceeds from selling machinery. The fees are tested as trading income, the loan as repayable financing, and the machinery proceeds under recoupment and capital-gains rules. A bank-total approach would obscure these differences.
Common mistake: Adding every receipt to taxable revenue ignores repayment obligations, capital character, exemptions and specific inclusion provisions governing different transactions.
Official syllabus reference: [2]
32. Deductible company expenditure and start-up costs
Company expenditure is tested for actual incurral, income-production connection, trade purpose, capital character and statutory restrictions. Recording an expense in the income statement does not establish deductibility. Conversely, a tax deduction can sometimes arise through a specific provision despite a different accounting treatment. Pre-trade costs require their designated relief and any utilisation restriction once the trade begins. Separate capital acquisition costs, owner distributions and private or prohibited expenditure from ordinary operating costs. For accounting-profit reconciliations, reverse non-deductible expenses already charged and claim qualifying tax deductions only once.
Worked example: A company charges launch advertising, machinery acquisition and a statutory fine to expenses. The tax reconciliation tests advertising under applicable start-up rules, replaces machinery expensing with qualifying capital relief, and reverses the fine where the supplied rules deny a deduction.
Common mistake: Assuming audited accounting expenses are automatically deductible confuses financial-reporting recognition with the separate conditions imposed by tax legislation.
Official syllabus reference: [2]
33. Research approval and enhanced deduction
Research and development relief depends on qualifying activities, eligible expenditure and the applicable approval and timing requirements. Describing routine commercial work as research is insufficient. Where enhanced relief applies, distinguish the total permitted tax deduction from the additional adjustment needed when accounting profit already includes the ordinary expense. Expenditure on different asset or activity categories may require separate treatment. Maintain evidence linking the approved activity to the claimed costs. The syllabus establishes this relief's relevance but does not verify a numerical enhancement rate; calculation exercises must therefore supply the applicable percentage and qualification facts.
Worked example: Assume eligible research costs are R200,000 and total permitted relief is 150%. The total deduction is R300,000. If accounting profit already deducts R200,000, the reconciliation claims only another R100,000, unless it first reverses the original expense.
Common mistake: Deducting an enhanced total on top of an unreversed accounting expense duplicates the ordinary component of the research deduction.
Official syllabus reference: [2]
34. Capital-allowance reconciliation and asset registers
Company capital allowances require an asset-by-asset tax schedule showing qualifying cost, category, use dates, prior allowances and disposals. Accounting depreciation is normally reversed where statutory capital relief replaces it. Manufacturing assets, qualifying buildings and assets eligible for small business corporation incentives can follow different rules. Determine eligibility before applying a rate, and avoid imposing annual time apportionment on an allowance whose statute provides another pattern. On disposal, update recoupment and capital-gain information as well as the remaining schedule. A tax asset register preserves continuity between acquisition, annual deductions and eventual disposal.
Worked example: Accounting profit includes R70,000 depreciation, while supported tax schedules allow R95,000. The reconciliation adds R70,000 and deducts R95,000, reducing taxable income by R25,000 overall. Separate schedules preserve the different future tax values of the individual assets.
Common mistake: Deducting tax allowances without reversing depreciation grants duplicate relief when the accounting-profit starting point already includes the depreciation expense.

35. Interest recognition and borrowing purpose
Interest received and incurred requires attention to the applicable accrual rules and the instrument's terms, rather than relying only on cash movements. For interest deductions, identify how borrowed funds are used and whether the relevant deduction conditions and restrictions are satisfied. Borrowing to produce taxable trading income differs from borrowing for a non-income-producing purpose. Capitalised accounting treatment does not alone decide tax timing. Distinguish principal repayments from interest, and separate exchange movements on foreign debt from its financing charge. Apply only the interest provisions within TX-ZAF scope rather than importing excluded specialist instrument rules.
Worked example: A company pays R120,000 to a lender, comprising R100,000 principal and R20,000 interest. Only the interest component enters the interest-deduction analysis. The company then establishes the funds' trading use and the applicable timing rule before claiming relief.
Common mistake: Deducting an entire loan instalment treats repayment of borrowed capital as an expense and overstates the financing deduction.
Official syllabus reference: [2]
36. Brought-forward company loss utilisation
A brought-forward assessed loss is not automatically an unrestricted deduction against all current company income. Establish the available balance, continued entitlement and the annual utilisation limit applicable to the company and year. Calculate income before the loss on the correct basis, apply the relevant ceiling and carry forward the unused amount. Distinguish an ordinary assessed loss from an assessed capital loss, which follows capital-gains rules. A company can therefore have a large accumulated loss and still owe current normal tax. Numerical ceilings must be supplied or taken from the applicable examinable legislation.
Worked example: Assume income before losses is R900,000 and the exercise permits utilisation of only R600,000. A R1,400,000 brought-forward loss leaves taxable income of R300,000 and an unused loss of R800,000, despite the company's larger accumulated loss balance.
Common mistake: Eliminating current income whenever the loss balance is larger ignores utilisation limits and may understate tax payable for the year.
Official syllabus reference: [2]
37. Resolving a comparable service charge for transfer pricing
For an affected cross-border connected-party service transaction, evidence that work occurred establishes only part of the analysis. Determine the functions performed, assets used, risks assumed and commercial terms, then compare the charge with an appropriate independent transaction or pricing method. Comparable service hours must reflect similar expertise, scope and contractual responsibilities; material differences require supportable adjustments. Where the connected charge exceeds the arm's-length amount and reduces South African taxable income, quantify the relevant primary adjustment. A signed invoice or group pricing policy does not independently establish an arm's-length price.
Worked example: A South African company pays its foreign parent R150,000 for 100 engineering hours. An independent supplier quotes R1,000 hourly for matching expertise, scope, risks and terms, with no adjustment needed. Assume the transaction is affected and no secondary adjustment is required. The arm's-length charge is R100,000; taxable income increases R50,000.
Common mistake: Proving that engineering work was delivered does not prove that the connected supplier's hourly price was commercially comparable.
Official syllabus reference: [2]
38. Exchange differences on foreign-currency liabilities
A foreign-currency liability exposes a company to changes in the rand amount needed to settle it. Where the applicable tax exchange provisions require recognition, compare translated values at the relevant recognition, year-end and settlement dates. A weakening rand increases the rand liability and ordinarily creates a loss; a strengthening rand has the opposite effect. Keep the underlying purchase or borrowing separate from the exchange movement and interest charge. Determine whether the item and taxpayer fall within the governing provisions before adopting the accounting result. Specialist hedging instruments require separate rules and may be outside scope.
Worked example: Assume a qualifying €20,000 payable is first translated at R20 per euro and must be remeasured at R21. The liability rises from R400,000 to R420,000. Under the supplied recognition rule, the company records a R20,000 exchange loss.
Common mistake: Calling a rising rand value of foreign debt a gain reverses the settlement burden and produces the wrong tax adjustment.
Official syllabus reference: [2]
39. Company tax waterfall and donation ceiling
A comprehensive company computation reconciles accounting profit to tax-adjusted income, incorporates relevant capital gains, applies assessed-loss relief and calculates qualifying donation deductions in the prescribed order. The donation ceiling uses its statutory base, not automatically turnover or accounting profit. Apply the company or qualifying small business corporation rate only after taxable income is established. Provisional payments then reconcile liability to the amount payable or refundable. This staged approach prevents circular donation calculations, duplicate deductions and confusion between tax expense and cash settlement. Each adjustment should state whether it increases or decreases the starting profit.
Worked example: Under supplied assumptions, income after loss relief but before donations is R700,000. A 10% ceiling allows R70,000. If qualifying donations were R50,000, deduct R50,000 and calculate tax on R650,000 before reconciling provisional payments already made.
Common mistake: Calculating the donation ceiling from accounting profit can use a base containing exempt income, disallowed expenses or unrelieved losses.
Official syllabus reference: [2]
40. In-specie dividends and separate disposal consequences
An in-specie dividend transfers an asset rather than cash. The distributing company bears the dividends-tax liability, calculated using the relevant statutory valuation and rate, subject to applicable exemptions or reductions. This differs from the usual cash-dividend withholding mechanism. Separately, transferring the asset can trigger normal-tax consequences, including recoupment or a capital gain under the relevant disposal rules. The dividend is not an ordinary operating deduction. Keep the asset-disposal computation, normal-tax liability and dividends-tax liability distinct, and do not gross up a supplied market value unless the applicable facts and rules require that treatment.
Worked example: Assume an asset distributed to an unexempt individual has relevant market value R400,000 and dividends tax is 20%. The company owes R80,000 dividends tax. Any recoupment or capital gain on transferring the asset requires a separate computation using its tax history.
Common mistake: Withholding part of a non-cash asset as though it were a cash dividend overlooks the company's own in-specie dividends-tax liability.
Official syllabus reference: [2]
Chargeable capital gains
41. Disposal events and the capital-gains tax base
Capital gains taxation operates through the income-tax system by including the prescribed portion of a net capital gain in taxable income. First identify an asset and a disposal event, which can include sale, donation, exchange or a deemed disposal under applicable rules. Cash receipt is not essential for every disposal. Residence and asset location affect scope, but overseas assets and detailed double taxation relief are excluded from this TX-ZAF area. Distinguish capital assets from trading stock and ordinary revenue transactions. An accounting profit on disposal does not by itself establish the taxable capital gain.
Worked example: A business exchanges an investment asset for another asset without receiving cash. The exchange still requires disposal analysis, valuation of proceeds and identification of base cost. The absence of cash does not automatically defer the original asset's capital-gains consequences.
Common mistake: Assuming capital gains arise only on cash sales overlooks donations, exchanges and deemed disposal events recognised by the tax rules.
Official syllabus reference: [2]
42. Proceeds and allowable base cost
A capital gain generally compares disposal proceeds with allowable base cost. Base cost can include qualifying acquisition expenditure, incidental transaction costs and qualifying improvements, subject to statutory exclusions and coordination with deductions already obtained. An expense cannot simply be counted again because it appears in an asset ledger. Proceeds may need adjustment where market-value rules or recoupment coordination apply. Separate selling costs, acquisition costs, repairs and improvements before computing the result. Use tax-supported amounts rather than accounting carrying value, because depreciation, revaluations and tax allowances can make those measures substantially different.
Worked example: Assume an investment asset cost R250,000, incurred R10,000 qualifying acquisition fees and R20,000 qualifying improvements, then sold for R340,000 with R5,000 qualifying selling costs. A supported base cost of R285,000 gives a R55,000 capital gain.
Common mistake: Using net book value as base cost can import accounting depreciation and omit qualifying costs or tax-specific adjustments.
Official syllabus reference: [2]
43. Calculating and comparing valuation-date base-cost methods
For an eligible asset acquired before 1 October 2001, establish its valuation-date value using an available method and add qualifying later expenditure. Market value uses a properly supported valuation at that date. Time apportionment broadly adds original expenditure to the pre-valuation fraction of the gain, using the applicable period-counting rules and adjusted proceeds. Another method uses a prescribed percentage of net proceeds. Market-value gain and loss limitations must also be checked, particularly where expenditure and valuation straddle proceeds. An election cannot simply manufacture a loss by selecting the highest valuation.
Worked example: Assume cost R200,000, net proceeds R1 million, six pre-valuation years, fourteen later years, no later costs and no applicable limitation. Time-apportioned value is R200,000 + R800,000 × 6/20 = R440,000. Supported market value is R500,000; an assumed 20% alternative gives R200,000. Selecting market value produces a R500,000 gain.
Common mistake: A valuation-date method establishes the starting value; later qualifying expenditure and any applicable gain or loss limitation still require consideration.
Official syllabus reference: [2]
44. Annual exclusion, capital losses and inclusion rates
Aggregate capital gains and allowable capital losses using the prescribed sequence, apply the individual's annual exclusion where available, and account for assessed capital losses before determining the net capital gain. The inclusion rate converts that net gain into taxable income; it is not itself the final tax rate. Companies and individuals can have different inclusion treatment, and companies do not simply inherit an individual's annual exclusion. Capital losses generally remain within the capital-gains system rather than reducing salary or trading profit. Restricted or disregarded losses require separate handling before ordinary aggregation.
Worked example: Using supplied assumptions, an individual has R150,000 gains, R30,000 allowable losses and a R40,000 annual exclusion. The remaining R80,000, with no brought-forward loss, produces R32,000 taxable capital gain at a 40% inclusion rate; normal tax is calculated afterwards.
Common mistake: Calling the inclusion percentage the capital-gains tax rate ignores the later application of normal income-tax rates to the included amount.
Official syllabus reference: [2]
45. Personal-use exclusions and asset exceptions
The personal-use asset exclusion generally removes gains and losses on qualifying assets used mainly outside trade by individuals, subject to statutory exceptions. Asset character matters as well as use: immovable property, financial instruments and other specified categories cannot automatically be treated like household furniture. Business use can also change eligibility. Excluding a gain does not imply every loss becomes deductible; the exclusion commonly disregards both. Establish ownership, use and the relevant exception before aggregating results. Separate primary-residence relief from the general personal-use mechanism because residential property has its own conditions and limitations.
Worked example: An individual sells family dining furniture and separately sells investment shares. The furniture is tested under the personal-use exclusion. The shares require their own capital-gains analysis, even though both assets were owned personally and neither belonged to a company.
Common mistake: Equating personal ownership with personal-use exclusion would incorrectly remove investment assets and property from their own capital-gains rules.
Official syllabus reference: [2]
46. Primary-residence use and apportionment
Primary-residence relief applies only where the residence and use conditions are met. Determine ownership, ordinary residential occupation and the extent of domestic versus trade use. Periods or areas not qualifying may require apportionment, while particular statutory concessions can modify the treatment. Apply the supplied exclusion to the qualifying gain using the prescribed sequence rather than assuming the entire property is exempt. Joint ownership requires attention to each owner's share and the relevant limit allocation. A property described as a home can still contain a commercially used portion or non-qualifying period affecting the result.
Worked example: Assume a home's gain is R900,000 and the supplied rules allocate 20% to exclusively business-used space. The R180,000 business portion is analysed separately, while the R720,000 qualifying residential portion is tested against the applicable primary-residence relief.
Common mistake: Excluding every gain on a property called a family home ignores business use, ownership shares and periods that may not qualify.
Official syllabus reference: [2]
47. Spousal rollover preserves latent gain
Qualifying transfers between spouses can receive rollover treatment, postponing recognition rather than permanently eliminating the asset's accrued gain. The recipient generally takes over relevant tax history under the applicable rules, allowing the latent gain to remain embedded until a later taxable disposal. Establish that the parties and transfer satisfy the provision; do not apply the same treatment to every family relationship. A later sale requires the carried-over basis rather than an assumed market-value cost. Distinguish capital-gains rollover from any separate income-tax, transfer-duty or other consequences, which require their own rules.
Worked example: Assume a qualifying spousal transfer carries over a R200,000 base cost when market value is R350,000. If the recipient later sells for R420,000, the starting capital gain is R220,000, rather than R70,000 based on the transfer-date market value.
Common mistake: Treating rollover as a market-value step-up erases the deferred gain and understates the recipient spouse's later disposal result.
Official syllabus reference: [2]
48. Connected-person market value and restricted losses
Connected-person transfers require separate consideration of proceeds substitution and capital-loss restrictions. A non-arm's-length transfer can require market-value proceeds even where the actual consideration differs. A loss on a connected-person disposal may be restricted for use against specified qualifying gains rather than freely offset against unrelated gains. These are different mechanisms: selling at market value does not necessarily remove the loss restriction. Identify the relationship, transaction terms, actual and deemed proceeds, and loss-utilisation conditions. Track restricted losses separately from ordinary assessed capital losses so later utilisation follows the relevant statutory route.
Worked example: Assume an asset with R160,000 base cost is sold to a connected person for market value of R100,000. The R60,000 loss may still be restricted, despite arm's-length pricing, and cannot automatically shelter an unrelated gain realised in the same year.
Common mistake: Assuming market-value consideration cures every connected-person consequence confuses proceeds valuation with the separate restriction on capital-loss utilisation.
Official syllabus reference: [2]
49. Applying replacement-asset relief after an insured destruction
Insurance compensation following an asset's destruction can generate a capital gain because compensation is disposal proceeds. Replacement-asset relief requires the specified involuntary-disposal event, qualifying replacement property, reinvestment and compliance with the applicable acquisition and use deadlines. Relief defers recognition rather than eliminating the economic gain. Its mechanism depends on the replacement asset: qualifying non-depreciable property can carry the deferred gain through a reduced base cost, while depreciable replacements can require recognition linked to allowances. Identify the relevant mechanism and separate any ordinary-income recoupment before determining the capital-gain relief.
Worked example: Assume relief requires full reinvestment, acquisition within six months and use within twelve. Destroyed non-depreciable business property yields R500,000 insurance against R320,000 base cost. A qualifying R520,000 replacement is acquired in month four and used in month five. With no recoupment, defer R180,000; replacement base cost becomes R340,000.
Common mistake: Replacing an insured asset does not automatically secure relief; the reinvestment, replacement category and timing conditions must all be satisfied.
Official syllabus reference: [2]
50. Part-disposal cost allocation and business-asset relief
A part-disposal requires allocating base cost between what is sold and what remains, generally using the relevant relative market values where that rule applies. The retained cost must remain available for future disposal, preventing either double deduction or permanent loss of basis. After calculating the gain, separately test any small-business asset relief or micro-business treatment using its ownership, qualifying-asset and other statutory conditions. Such relief does not justify changing the cost-allocation arithmetic. Identify whether a problem concerns only part of an asset, an interest in a business or qualifying business assets sold under a separate relief provision.
Worked example: An asset has R500,000 base cost. A disposed part represents 30% of the combined relevant market values, so R150,000 cost is allocated to that sale and R350,000 retained. Any claimed small-business relief is then tested on the computed gain.
Common mistake: Deducting the whole original cost on a partial sale overstates the current deduction and leaves no defensible basis for the retained asset.
Official syllabus reference: [2]
Value added tax
51. Taxable supplies and VAT registration
VAT registration depends on carrying on an enterprise and meeting the applicable compulsory-registration conditions, or satisfying voluntary-registration requirements. Measure the relevant taxable supplies over the prescribed period; accounting profit is not the threshold base. Zero-rated supplies are taxable supplies, while exempt activities have different consequences. Voluntary registration can permit qualifying input recovery but also brings output-tax, invoicing and compliance obligations. Deregistration requires its own conditions and may trigger adjustments on retained assets. Use supplied registration thresholds and dates rather than treating an unverified figure as universally current for every examination or taxpayer.
Worked example: A start-up makes standard-rated sales and qualifying zero-rated exports. Both categories enter its taxable-supplies analysis for registration. The owner compares the supplied threshold with those supplies, rather than excluding exports merely because their output VAT rate is zero.
Common mistake: Testing registration against net profit or only standard-rated sales can omit taxable zero-rated supplies and misidentify the registration obligation.
Official syllabus reference: [2]
52. Zero-rated, exempt and mixed supplies
Standard-rated and zero-rated supplies both belong to the taxable-supply system, but zero rating applies a zero output rate where its conditions are met. Exempt supplies are outside that taxable category and generally do not support input recovery in the same way. For a transaction containing different elements, identify what is actually supplied and whether the law requires separate treatment or a single characterised supply. Documentary conditions can be essential to zero rating. The syllabus includes recognising mixed supplies but excludes partial exemption and partial supplies, so do not extend this lesson into detailed apportionment regimes.
Worked example: A vendor sells standard-rated goods and separately makes a qualifying zero-rated export. The export has no output VAT but remains a taxable supply supporting qualifying input recovery. An exempt receipt would require different treatment rather than being another form of zero rating.
Common mistake: Using exempt and zero-rated interchangeably conceals their different effects on taxable turnover, supporting documents and entitlement to recover input tax.
Official syllabus reference: [2]
53. Time of supply and VAT-inclusive values
On the invoice basis, the general time-of-supply rule commonly uses the earlier of invoice or payment, subject to special provisions. Delivery date alone does not always determine the return period. Establish the applicable timing rule before calculating value and output tax. For a VAT-exclusive price, multiply by the rate; for a VAT-inclusive price, extract tax using rate divided by one plus the rate. Connected-person or other special valuation rules may alter the value to use. The cash accounting scheme is excluded from this syllabus, so ordinary non-payment does not justify deferring invoice-basis output tax.
Worked example: Assume 15% VAT and no special rule. A R11,500 VAT-inclusive invoice issued before payment contains R11,500 × 15/115 = R1,500 VAT. If issuing the invoice is the first time-of-supply event, that output tax belongs to the invoice period.
Common mistake: Multiplying a VAT-inclusive amount by 15% calculates tax on a price already containing tax and overstates the VAT component.
Official syllabus reference: [2]
54. Tax invoices and blocked input VAT
Input VAT recovery requires more than a purchase payment. Establish the vendor's entitlement, the connection with taxable supplies and the prescribed supporting document, including required supplier, recipient, transaction and tax information where applicable. Some categories are specifically blocked, subject to statutory exceptions; entertainment and certain motor-car acquisitions require particular care. A valid invoice does not override a substantive prohibition, and a business purpose alone does not cure missing documentation. Distinguish an invoice stating a gross price from a compliant tax invoice. Use the correct full or simplified invoice requirements for the transaction.
Worked example: A vendor holds a compliant invoice for ordinary stock used wholly in taxable sales and another for entertainment expressly blocked under the exercise. It claims the stock input VAT but excludes the entertainment amount despite having documentation for both purchases.
Common mistake: Claiming every VAT amount on an invoice ignores blocked categories and the separate requirement that the acquisition supports qualifying taxable activity.
Official syllabus reference: [2]
55. Imports, exports and evidence-based zero rating
Imports and exports use different VAT mechanisms. Imported goods can attract import VAT determined under the applicable customs and VAT valuation rules, with input recovery requiring entitlement and supporting import documents. Export sales may qualify for zero rating only where the substantive and documentary conditions are met. A foreign customer or foreign-currency invoice does not alone prove export treatment. Imported services require their own charging analysis rather than automatic treatment as imported goods. Separate customs duty, import VAT and supplier charges so the same tax is not extracted or deducted twice in the VAT return.
Worked example: A vendor receives an import document showing R18,000 deductible import VAT and separately invoices an export customer. It uses the stated import VAT amount directly, while establishing the export conditions and retained evidence before applying a zero rate to the sale.
Common mistake: Zero-rating every sale to an overseas buyer overlooks delivery arrangements and documentary requirements that can determine the correct VAT treatment.
Official syllabus reference: [2]
56. Bad-debt adjustments and VAT return reconciliation
A vendor that previously accounted for output VAT may obtain bad-debt relief when the debt meets the applicable irrecoverability and write-off conditions. Mere late payment is insufficient. Extract the VAT component from an inclusive debt using the relevant fraction, and recognise the required adjustment if an amount is later recovered after relief. Reconcile sales, output adjustments, supported inputs and debt adjustments to the return period. Late or incorrect returns can create penalties and interest under separate rules. Distinguish return submission, payment and record retention obligations rather than assuming one completed action satisfies the others.
Worked example: Using 15% VAT, a qualifying R46,000 inclusive write-off contains R6,000 VAT relief. A later R11,500 inclusive recovery contains R1,500 VAT that must be restored under the assumed recovery rule, preventing permanent relief for debt eventually collected.
Common mistake: Keeping the original VAT relief after recovering the debt understates the tax adjustment required once the customer pays.
Official syllabus reference: [2]
Employability and technology skills
57. Digital exhibit mapping and source control
Digital tax work requires linking each figure to its source exhibit, period, unit and tax character. Extract relevant information without losing whether an amount is inclusive of VAT, already deducted in profit or subject to a supplied assumption. A compact source map can connect transaction facts to the computation line they affect. Distinguish original inputs from calculated outputs and amendments, so updated information replaces the right value. This is a technical information-handling skill: copying figures accurately is insufficient if their accounting status or assessment period is lost during transfer between windows.
Worked example: An exhibit lists depreciation already charged in profit and a separate capital allowance. The candidate records both with their source labels, then adds back the former and deducts the latter. Preserving their status prevents two deductions when moving figures into a spreadsheet.
Common mistake: Copying numbers without labels or period references can preserve arithmetic accuracy while producing a tax computation based on the wrong facts.
Official syllabus reference: [2]
58. Formula dependencies and independent checks
Spreadsheet formulas should express the tax computation's dependency structure: inputs feed adjustments, taxable income feeds tax, and payments reconcile the liability. Reference source cells instead of repeatedly typing derived values. Use brackets, percentages and signs deliberately, and distinguish a formula error from a mistaken legal assumption. An independent check should test the result through a different relationship, such as comparing tax allowances with depreciation or reconciling opening and closing loss balances. Repeating the same formula elsewhere offers little additional assurance. Exact available functions depend on the response environment, so transparent arithmetic remains valuable.
Worked example: Profit is R400,000, depreciation R50,000 and tax allowance R80,000. A formula gives R370,000 taxable income. Independently, the allowance exceeds depreciation by R30,000, so taxable income should be R30,000 below profit; the second relationship confirms the adjustment's direction.
Common mistake: Checking a formula by copying it into another cell reproduces the same error rather than independently testing the underlying computation.
Official syllabus reference: [2]
59. Window navigation and controlled revisions
When requirements, exhibits and response tools occupy separate views, maintain the connection between the active requirement and its working. Read a figure's surrounding qualifications before transferring it, and place revisions in the controlling input rather than editing disconnected totals. After changing an assumption or source amount, inspect dependent calculations and any narrative conclusion. Distinguish replacing an answer from appending an alternative, which can leave contradictory submissions. Efficient navigation reduces transcription and omission errors, but should preserve the audit trail showing how the answer follows the supplied facts and responds to the requested output.
Worked example: A revised exhibit changes an asset's use date from twelve months to nine months. The candidate updates the allowance input, recalculates taxable income and tax, and revises the written balance payable so the narrative agrees with the amended spreadsheet result.
Common mistake: Correcting only the final displayed answer can leave supporting workings and narrative conclusions inconsistent with the revised source information.
Official syllabus reference: [2]
60. Presenting a reviewable tax computation
A professional tax response makes its reasoning inspectable through clear labels, units, subtotals and concise explanations of judgmental adjustments. Separate taxable-income deductions from tax credits and payments. Show calculation bases for restricted relief, retain useful working precision and round only as required. For discursive requirements, connect the applicable rule to the specific facts and resulting treatment rather than listing disconnected legislation. Effective presentation helps a reviewer identify both technical understanding and arithmetic errors. A polished final number without workings is less informative than a structured computation whose assumptions and stages can be followed.
Worked example: A company answer shows profit reconciliation, assessed-loss utilisation, the donation ceiling, taxable income, normal tax and provisional payments in sequence. A separate line explains an in-specie dividends-tax liability, preventing its accidental inclusion as either an income deduction or a normal-tax payment.
Common mistake: Presenting one unexplained net figure hides whether deductions, credits, payments and separate taxes have been placed at the correct computational stages.
