ICSAN Financial Accounting common mistakes

ICSAN Financial Accounting · Understand the traps and how to avoid them.

Mistake 1

When asked to treat a payment received in advance as a liability, candidates debit the bank account and credit sales revenue, closing the year with no deferred income balance.

They read the cash receipt as a completed sale because cash has moved, ignoring the performance obligation and the accrual basis. The conceptual framework's definitions of income and liability are memorised as slogans rather than applied to a dated transaction.

What to do instead

Before journalising any receipt, ask whether the entity has delivered the goods or service by the reporting date. If not, the credit goes to a contract liability or deferred income account and is released to revenue only as performance occurs. Practise with three dates: cash received, service delivered, year end.

Mistake 2

Candidates post every transaction directly to the trial balance or the statement of financial position, skipping the books of prime entry, so the audit trail is absent and the sales day book total never agrees to the receivables control account.

Exams compress time, so candidates take the shortest route to a number. They also confuse the ledger with the journal and do not see that control accounts are fed by book-of-prime totals, not individual invoices.

What to do instead

Work in a fixed sequence for every question: source document, book of prime entry, ledger posting, trial balance. Write the book of prime entry name beside each figure you compute. If you cannot name the book, you have not finished the transaction.

Mistake 3

In a bank reconciliation, candidates adjust the cash book for unpresented cheques and lodgements not yet credited, and adjust the bank statement balance for bank charges and standing orders, reversing the two sides.

The two lists of items look similar and both involve timing. Candidates memorise 'adjust the cash book' without learning which party already knows about each item.

What to do instead

Test each item with one question: has our ledger recorded it? Items the bank knows but we do not (charges, interest, direct debits, dishonoured cheques) go in the cash book. Items we know but the bank does not (unpresented cheques, uncredited lodgements) go in the reconciliation statement. Redo the same question from the bank's side to prove symmetry.

Mistake 4

On correction of errors, candidates reverse the wrong leg of a one-sided entry, or clear a suspense account balance to the statement of profit or loss without first checking whether all errors are found.

They treat the suspense account as a plug rather than evidence of an incomplete double entry. Without a clear map of debits and credits already posted, the correcting entry doubles the original mistake.

What to do instead

For each error, write the entry that was made and the entry that should have been made, side by side, then derive the correction as the difference. The suspense balance must fall to nil only through identified corrections; if a residue remains, state it as an unresolved difference, not as income.

Mistake 5

Candidates compute depreciation on the closing carrying amount under the reducing balance method, or charge a full year on an asset bought mid-year when the question specifies time apportionment.

The straight-line habit of applying a rate to cost carries over. The phrase 'reducing balance' is read as 'a smaller number' rather than 'a rate on the opening carrying amount'.

What to do instead

Write the formula at the top of your workings: straight line equals cost less residual value over useful life; reducing balance equals rate times opening carrying amount. For mid-year acquisitions, show months owned explicitly before multiplying. Keep a disposal working that separates proceeds, carrying amount and the resulting gain or loss.

Mistake 6

When preparing partnership accounts, candidates split profit using the opening capital ratio even though the deed specifies interest on capital, salary and a residual sharing ratio, and they omit the current accounts.

They collapse the appropriation into a single division and forget that capital accounts stay static while current accounts absorb interest, salary, drawings and profit share.

What to do instead

Build the appropriation account line by line: profit for the year, less salary, less interest on capital, equals residual, then split by the profit-sharing ratio. Post each partner's share to a current account, then deduct drawings. Reconcile the total of current accounts to the equity section of the statement of financial position.

Mistake 7

Candidates prepare a statement of cash flows by starting with retained profit and adding back every non-cash item they can recall, without reconciling the movement in working capital or separating investing and financing flows correctly.

The indirect method is memorised as a list rather than as a bridge from profit to operating cash. Signs on increases and decreases in current assets and liabilities are guessed.

What to do instead

Use a three-column working: profit before tax, adjustments for non-cash and non-operating items, then working capital movements. For each working capital line, state the direction in words ('receivables increased, so cash is lower') before writing the sign. Prove the closing cash figure against the statement of financial position.

Mistake 8

In ratio analysis, candidates calculate a ratio and then describe it ('the current ratio is 1.8') instead of interpreting it against a comparator, and they mix profit figures into balance sheet ratios or use closing rather than average figures where the question supplies both.

The arithmetic feels like the answer. Candidates also lack a structure for commentary, so they stop once the number appears.

What to do instead

For every ratio, write three lines: the calculation, the comparison (prior year, budget or industry), and the business consequence with a plausible cause. Check the numerator and denominator come from consistent bases, and use average balances for return-on-capital and receivable-day measures when opening figures are given.

Mistake 9

On public sector and not-for-profit questions, candidates apply full accrual commercial accounting to a fund or vote without recognising commitments, modified cash bases, or the fund accounting boundaries, and they treat restricted donations as unrestricted income.

The sole trader and company templates are over-learnt, and candidates have not studied the distinctive reporting objectives of stewardship and budgetary compliance in public entities.

What to do instead

Before answering, identify the reporting basis stated in the question (cash, modified cash, accrual), the fund structure and any restrictions on resources. Present receipts and payments or income and expenditure in the required format, and show restricted funds separately from general funds.

Mistake 10

Candidates answer ethics scenarios by naming a threat (self-interest, familiarity) but give no safeguard, and they cite confidentiality to justify withholding information that the professional duty to report requires them to escalate.

The conceptual framework of ethics is recalled as a list of five threats without practice in applying them to a named individual, a specific pressure and a decision to be made.

What to do instead

Use a fixed answer structure: identify the threat, explain why it arises in this scenario, state the safeguard (decline the engagement, disclose to those charged with governance, consult the professional body), and state the consequence of inaction. Distinguish confidentiality from the duty to report unlawful or fraudulent acts.
