What this dot point is asking

SEAB wants you to account for irrecoverable debts and the allowance for impairment of trade receivables, and to explain the prudence behind them. Receivables are rarely all collectable, and the syllabus tests whether you can write off the hopeless ones and estimate an allowance for the doubtful rest. The central insight is that prudence requires receivables to be shown at the amount realistically expected to be collected, so known bad debts are written off and likely future losses are provided for through an allowance.

The answer

The accounting has two distinct elements that often appear together: irrecoverable debts (specific debts known to be uncollectable, written off in full) and the allowance for impairment (an estimate of further debts that may not be collected, adjusted each year).

Writing off an irrecoverable debt

When a specific debt is known to be uncollectable, it is written off:

Debit Irrecoverable debts expense; credit Trade receivables (the customer's account).

This removes the debt and charges the loss to the income statement. If a debt previously written off is later recovered, the recovery is recorded as income (debit cash, credit a bad debts recovered account).

The allowance for impairment

Beyond specific write-offs, experience shows a proportion of the remaining receivables will probably not be collected. An allowance for impairment estimates this. The key rule is that only the change in the allowance is the expense:

\text{Expense} = \text{closing allowance} - \text{opening allowance}

An increase in the allowance is an expense; a decrease is a credit (income) in the income statement. The allowance is shown as a deduction from gross receivables.

Net receivables on the statement of financial position

The figure shown as a current asset is:

\text{Net trade receivables} = \text{gross receivables (after write-offs)} - \text{allowance for impairment}

The order matters: write off specific irrecoverable debts first, then calculate the allowance on what remains.

Worked example

At year end, gross trade receivables are $\$ 120,000 $. A specific debt of$ \ $8\,000$ is irrecoverable and must be written off. The business then makes an allowance for impairment of $5\%$ of the remaining receivables. The opening allowance was $\$ 4,500$. Compute the expense and net receivables.

Step 1: Write off the irrecoverable debt

Receivables after write-off $= 120\,000 - 8\,000 = \$ 112,000 $. The$ \ $8\,000$ is an irrecoverable debts expense.

Step 2: Compute the required closing allowance

5\% \times 112\,000 = \$5\,600

Step 3: Find the change in the allowance

Opening allowance $\$ 4,500 $; closing required$ \ $5\,600$ ; increase $= 5\,600 - 4\,500 = \$ 1,100$ (an expense).

Step 4: Total expense and net receivables

Total impairment expense $= 8\,000 + 1\,100 = \$ 9,100 $. Net receivables$ = 112,000 - 5,600 = \ $106\,400$ on the statement of financial position.

Note that only the $\$ 1,100 $increase in the allowance is expensed, not the whole$ \ $5\,600$ , because the opening $\$ 4,500$ was already charged in a prior year.

Examples in context

Example 1. A bankrupt customer and a cautious allowance. A wholesaler learns a customer owing $\$ 6,000 $has gone bankrupt, so it writes the debt off. On the remaining$ \ $94\,000$ of receivables, experience suggests $3\%$ will not pay, so it carries an allowance of $\$ 2,820 $. The statement of financial position shows net receivables of$ 94,000 - 2,820 = \ $91\,180$ , a realistic estimate of what will actually be collected.

Example 2. A recovery in a later year. A debt of $\$ 2,000$ written off last year is unexpectedly paid this year. The business records it as bad debts recovered (income), not as a change to current receivables. This keeps the prior write-off intact and recognises the windfall in the period it arises, illustrating that recoveries are treated as income rather than reversing the original entry.

Try this

Q1. Gross receivables are $\$ 50,000 $; a$ \ $2\,000$ debt is written off; a $4\%$ allowance is required. Find net receivables. [3 marks]

Cue. After write-off $= 48\,000$ ; allowance $= 4\% \times 48\,000 = \$ 1,920 $; net receivables$ = 48,000 - 1,920 = \ $46\,080$ .

Q2. The allowance for impairment falls from $\$ 3,000 $to$ \ $2\,200$ . State the effect on the income statement. [2 marks]

Cue. The $\$ 800$ decrease is credited to the income statement (income), increasing profit, because less is now expected to be lost.

Q3. Explain why an allowance for impairment is consistent with prudence. [2 marks]

Cue. Prudence requires recognising foreseeable losses and not overstating assets; the allowance reduces receivables to the amount likely to be collected before any specific debt has failed.

Exam-style practice questions

Practice questions written in the style of SEAB exam questions on this dot point, with worked answer explainers. The year tag is the paper they imitate, not the source.

Original7 marksAt year end trade receivables are

\

80\,000

before adjustments. A debt of

5\,000

is to be written off as irrecoverable, and an allowance for impairment of

4\%

is to be made on the remaining receivables. The opening allowance was

\

2\,000$. Calculate the impairment expense for the year and the net receivables.

Show worked answer →

Step 1 - write off the irrecoverable debt: Receivables fall to $80\,000 - 5\,000 = \$ 75,000 $. The$ \ $5\,000$ is an expense.
Step 2 - calculate the required allowance: $4\% \times 75\,000 = \$ 3,000$.
Step 3 - find the change in the allowance: Opening allowance $\$ 2,000 $, required$ \ $3\,000$ , so the allowance must increase by $3\,000 - 2\,000 = \$ 1,000$ (an expense).

Total impairment expense $=$ irrecoverable debt $+$ increase in allowance $= 5\,000 + 1\,000 = \$ 6,000$.

Net receivables on the statement of financial position $= 75\,000 - 3\,000 = \$ 72,000$.

Markers reward writing off the debt first, basing the allowance on the reduced receivables, charging only the increase in the allowance, the total expense of $\$ 6,000 $, and net receivables of$ \ $72\,000$ .

Original5 marksExplain the difference between writing off an irrecoverable debt and making an allowance for impairment, and why both are required by the prudence concept.

Show worked answer →

Writing off an irrecoverable debt removes a specific debt that is known to be uncollectable (for example the customer is bankrupt). The receivable is reduced and an expense recognised; the debt is gone from the books.

An allowance for impairment is a general or specific estimate of debts that may not be collected, even though no individual debt is yet known to have failed. It reduces net receivables without removing any particular debt, and is adjusted each year.

Both follow prudence: receivables must not be overstated and foreseeable losses must be recognised when probable. Writing off deals with debts already known to be bad; the allowance anticipates losses that experience suggests are likely among the remaining debts. Together they ensure the statement of financial position shows receivables at the amount realistically expected to be collected.

Markers reward the distinction (specific known loss versus estimated likely loss), that both reduce receivables and charge an expense, and the prudence justification.
