ITAA Toelatingsexamen common mistakes

ITAA Toelatingsexamen · Understand the traps and how to avoid them.

Mistake 1

Computing VAT or payroll amounts on the gross figure instead of first stripping out the tax base, so every subsequent line of the calculation is built on the wrong number.

Candidates recognise a familiar percentage and start multiplying immediately, skipping the step that establishes whether the amount given is inclusive or exclusive of VAT; the exam deliberately mixes both presentations across questions.

What to do instead

Before any calculation, write one line stating 'given amount is incl./excl. VAT' and derive the base explicitly (base = gross / 1.21 or / 1.09). Make the base a labelled intermediate figure on your scratch paper so later steps reference it rather than the original amount.

Mistake 2

Treating a private-use or mixed-use item as fully deductible for turnover tax or income tax, or conversely deducting nothing at all, instead of applying a proportional split.

Candidates learn the deduction rule and the private-use rule as separate topics and do not connect them when a single transaction triggers both; the exam tests exactly that overlap.

What to do instead

Build a habit of asking two questions for every input tax or cost item: 'is it business at all?' then 'is any part private?'. If mixed, compute the business percentage from the stated usage and show the split as two journal lines or two columns.

Mistake 3

Posting a transaction to the profit and loss account when it belongs on the balance sheet, or vice versa, particularly for prepayments, accruals, and asset purchases.

The wording of a scenario describes a cash movement, which pulls candidates toward the P&L, while the accounting treatment depends on the period the benefit relates to; candidates under time pressure follow the cash description.

What to do instead

For each item, state the recognition question out loud in one sentence: 'has the benefit been consumed in this period?' If not, it is a balance sheet item. Practise by classifying ten mixed items into P&L or balance sheet before writing any journal.

Mistake 4

Producing a trial balance or balance sheet that does not balance and then plugging the difference into a suspense or 'other' line to make it foot.

Time pressure plus the visible comfort of a balanced sheet leads candidates to hide the error rather than find it; markers award method points that a plug destroys, and the plug also signals the underlying error was never located.

What to do instead

Leave the difference visible and labelled. Apply a fixed search order: re-add each column, check each journal for equal debits and credits, check that every opening balance was carried once only. A shown difference with a documented search earns more than a forced balance.

Mistake 5

Applying the current-year tax rates and thresholds to an earlier year's facts, or ignoring the year stated in the question when selecting rates.

Candidates memorise the rates they studied most recently and the question's year reference is a single word buried in a long scenario, so it is easily missed.

What to do instead

Underline the tax year in the question before reading further, and write the applicable rates at the top of your answer space from memory before calculating. If the paper provides a rate table, use only that table and note which column you used.

Mistake 6

Confusing the moment a taxable event occurs with the moment payment is received, producing period misallocation in VAT returns or profit recognition.

Cash receipts are the most vivid fact in a scenario, so candidates anchor on the payment date even when the invoice date or supply date governs the period.

What to do instead

For every transaction, extract three dates (order, invoice, payment) and explicitly decide which one the regime uses. Write the chosen date and the reason next to the entry; this also secures method marks if the final figure is wrong.

Mistake 7

Answering a 'state and explain' or 'advise' question with a bare calculation and no written conclusion.

Candidates equate accounting exams with number-crunching and run out of time on the discussion parts, or believe the number speaks for itself; open questions in this exam carry marks specifically for reasoning and advice.

What to do instead

Split answer time by mark allocation, not by interest. For any advise-style question, finish with two or three sentences: the position, the consequence, and one caveat or alternative. Draft the conclusion first, then support it with the figures.

Mistake 8

Depreciating an asset from the date of payment rather than the date it was available for use, or switching between straight-line and reducing-balance methods mid-life without stating a reason.

The payment date is prominent in the scenario and the policy note on depreciation method is usually a short sentence that candidates skim past.

What to do instead

Circle the in-use date and the stated depreciation policy before calculating. Show the depreciation schedule as a small table with columns for year, opening carrying amount, charge, and closing amount, so any inconsistency in method is visible to you as you build it.

Mistake 9

Ignoring the difference between a legal form and its economic substance, for example treating a lease as a simple rental cost when the terms transfer substantially all risks and rewards.

Candidates classify by the label used in the scenario ('rental', 'hire') rather than by the terms, because classification criteria are learned abstractly and are not automatically triggered by scenario wording.

What to do instead

Keep a short mental checklist of classification indicators (term versus useful life, ownership transfer, bargain purchase option, present value of payments) and run it whenever an asset is used without being owned. State the classification and the indicator that decided it.

Mistake 10

Leaving the final answer unrounded, wrongly rounded, or in the wrong unit, so a correct method produces a figure the marker cannot credit.

Calculators carry full precision and candidates transcribe the display; the instruction on rounding and units is a single line in the question stem that is read before the candidate knows what the answer will be.

What to do instead

At the start of each question, note the required rounding and unit in the margin. At the end, restate the answer in the requested unit with the requested precision and, where relevant, a currency symbol or thousands separator, then re-read the requirement line once.
