Writing Off an Uncollectible Account

What a Write-Off Does

When a specific customer balance is determined to be uncollectible, the business removes that balance from accounts receivable. Under the allowance method, the loss was anticipated earlier through an estimate and a related adjustment to bad debt expense and the allowance for uncollectible accounts. The later write-off uses that allowance; it is not a second recognition of the expense.

This distinction matters because there are two different accounting events. The estimate recognizes expected credit losses for a period. A write-off removes a particular balance that is no longer expected to be collected. Confusing the two can record the same expected loss as expense twice.

Definition: A write-off under the allowance method removes a specific uncollectible customer balance from accounts receivable by debiting the allowance for uncollectible accounts and crediting accounts receivable for the same amount. It does not debit bad debt expense at the write-off date.

The allowance for uncollectible accounts is a contra-asset: it is presented as a reduction of gross accounts receivable when calculating net accounts receivable. It normally has a credit balance. For a write-off of amount $W$, the entry is:

\begin{aligned} \text{Debit: Allowance for Uncollectible Accounts} &\quad W\\ \text{Credit: Accounts Receivable} &\quad W \end{aligned}

The credit to accounts receivable removes the customer’s balance from the receivables records. The debit reduces the allowance’s credit balance. No cash is received or paid in this entry, and no bad debt expense is recorded in it.

Why Net Receivables Do Not Change

Net accounts receivable equals gross accounts receivable less the allowance’s signed balance. A credit balance in the allowance is positive for this calculation; a debit balance is negative. Before a write-off, let gross receivables be $G$, the allowance balance be $A$, and the specific balance written off be $W$. After the entry, gross receivables are $G-W$, and the allowance balance is $A-W$.

\begin{aligned} \text{Net receivables before} &= G-A,\\ \text{Net receivables after} &= (G-W)-(A-W)\\ &=G-W-A+W\\ &=G-A. \end{aligned}

The same amount is removed from both gross receivables and the allowance, so the net amount is unchanged. Since cash and other assets are also unchanged by the entry, total assets do not change at the write-off date. Bad debt expense does not change either: the entry uses the allowance account, not an expense account.

This arithmetic holds even if the allowance’s credit balance is smaller than the write-off and becomes a debit balance. That result may signal that the allowance needs to be reassessed, but it does not change the mechanics of the write-off. The write-off itself still removes equal amounts from gross receivables and the signed allowance balance.

Key result: Under the allowance method, a write-off decreases gross accounts receivable and the allowance by the same amount. It therefore leaves net accounts receivable, total assets, and bad debt expense unchanged at that date.

Worked Example: Writing Off a Balance Within the Allowance

At the start of a business day, a company has gross accounts receivable of $68,400 and a credit balance of $5,600 in its allowance for uncollectible accounts. It concludes that customer North Pier Design’s $1,250 balance is uncollectible and writes it off. Determine the entry and the balances and effects immediately after the write-off. Assume the allowance balance shown is the balance immediately before this entry.

Method: use the allowance method entry, then compare net receivables before and after. The amount written off is $1,250, so debit the allowance and credit accounts receivable for $1,250:

\begin{aligned} \text{Debit: Allowance for Uncollectible Accounts} &\quad \$1{,}250\\ \text{Credit: Accounts Receivable} &\quad \$1{,}250 \end{aligned}

The new gross accounts receivable balance is $68,400 − $1,250 = $67,150. The allowance’s new credit balance is $5,600 − $1,250 = $4,350.

Before the write-off, net receivables were $68,400 − $5,600 = $62,800. Afterward, they are $67,150 − $4,350 = $62,800. Thus net receivables and total assets are unchanged. Bad debt expense is also unchanged by this entry.

Check: Gross receivables fell by $1,250 and the credit allowance fell by $1,250, so their difference stayed constant. The common mistake avoided is recording another $1,250 of bad debt expense when the specific balance is written off.

Posting and Checking the Entry

A write-off is about a particular customer account, so accurate records should show both the general-ledger entry and the change to that customer’s detail in the receivables records. The general ledger records the total accounts receivable and allowance balances; the customer record shows which balance was removed. These amounts must agree.

Confirm the specific balance.
Identify the customer account and the amount management has determined to be uncollectible. Do not treat a general estimate for all customers as if it were a write-off of one named balance.

Record equal debits and credits.
Debit the allowance and credit accounts receivable for the amount being removed. The entry must balance, and it must not include cash if no cash changed hands.

Update both records and reconcile.
Reduce the customer’s detail balance and the general-ledger gross receivables balance. Reduce the allowance’s credit balance by the same amount, then check that net receivables have not changed.

A write-off does not mean the business has received payment. It means the business has removed an uncollectible amount from its receivables records. Nor does the entry establish that the estimate of total expected losses is adequate after the write-off; that is a separate assessment. Keep the specific write-off entry distinct from any separate adjustment to the allowance and bad debt expense.

Worked Example: A Write-Off Larger Than the Allowance Balance

Immediately before a write-off, a company has gross accounts receivable of $32,900 and a credit balance of $1,800 in the allowance. A customer balance of $2,300 is determined to be uncollectible. Find the entry and the resulting net receivables. Assume no other transactions occur at that time.

Method: record the full specific write-off, then treat the allowance’s debit balance as a negative signed balance. The entry is:

\begin{aligned} \text{Debit: Allowance for Uncollectible Accounts} &\quad \$2{,}300\\ \text{Credit: Accounts Receivable} &\quad \$2{,}300 \end{aligned}

The new gross receivables balance is $32,900 − $2,300 = $30,600. The allowance had a credit balance of $1,800, and the $2,300 debit makes its ending balance a $500 debit: $2,300 − $1,800 = $500.

For the net-receivables calculation, the debit allowance balance is negative $500. Before the write-off, net receivables were $32,900 − $1,800 = $31,100. Afterward, they are $30,600 − (−$500) = $31,100. The write-off still leaves net receivables and total assets unchanged, and it still does not record bad debt expense at that date.

Check: The change in gross receivables is −$2,300, and the change in the signed allowance is also −$2,300. Their difference therefore does not change. The common mistake avoided is writing off only $1,800 or forcing the allowance to zero by debiting bad debt expense for the excess. The specific balance is removed in full; the resulting debit balance may call for a separate review of the allowance.

Tracing More Than One Write-Off

If several specific balances are written off, each entry follows the same rule. The total debit to the allowance must equal the total credit to accounts receivable. Tracking the combined effect is a useful check, but the customer-level records should still identify each balance removed.

Worked Example: Reconciling Two Customer Write-Offs

A company has gross accounts receivable of $74,500 and a credit allowance balance of $6,200 immediately before two write-offs. It writes off $1,600 due from Summit Cartography and $900 due from Alder Workshop. Calculate the combined entry, ending balances, and the effect on net receivables and bad debt expense. Assume these are the only transactions being considered.

Method: add the specific balances, record the combined entry, and verify the net amount. The total to write off is $1,600 + $900 = $2,500. The combined entry is:

\begin{aligned} \text{Debit: Allowance for Uncollectible Accounts} &\quad \$2{,}500\\ \text{Credit: Accounts Receivable} &\quad \$2{,}500 \end{aligned}

Gross accounts receivable after both write-offs is $74,500 − $2,500 = $72,000. The allowance’s credit balance becomes $6,200 − $2,500 = $3,700.

Before the entries, net receivables were $74,500 − $6,200 = $68,300. After them, net receivables are $72,000 − $3,700 = $68,300. Thus total assets and bad debt expense are unchanged by these write-offs. In the customer records, Summit Cartography’s $1,600 and Alder Workshop’s $900 balances are each removed.

Check: The total decrease in gross receivables equals the decrease in the allowance’s credit balance: $2,500. The common mistake avoided is recording the correct combined amount in the general ledger but failing to remove each named customer balance from the detailed records.

Common Exam Trap

A frequent error is to debit bad debt expense when a specific account is written off. That treatment counts the loss again if the allowance method has already recognized an estimate through an earlier adjusting entry. The right question is: Is this entry estimating expected losses, or removing a specific balance? An estimate affects bad debt expense and the allowance; a write-off under the allowance method debits the allowance and credits accounts receivable.

For example, suppose the company writes off a specific $700 customer balance. The incorrect entry would debit bad debt expense $700 and credit accounts receivable $700. It would reduce the company’s income and total assets by $700 at the write-off date, while leaving the existing allowance untouched. The correction is to debit the allowance $700 and credit accounts receivable $700. That entry reduces gross receivables and the allowance equally, with no new expense and no change to net receivables.

This treatment is specific to the allowance method. Do not confuse it with a method that waits until a particular account is judged uncollectible to recognize expense; that is a different approach and is not the entry taught here.

Key takeaway: For a specific write-off under the allowance method, debit the allowance and credit accounts receivable for the same amount. Remove the customer balance, but do not record bad debt expense a second time. The equal reductions leave net receivables and total assets unchanged at the write-off date.

Check Your Understanding

For each problem, assume the stated allowance balance is immediately before the write-off and no other transactions occur unless specified. Determine the entry and requested effects.

A company has gross accounts receivable of $51,200 and a $4,700 credit allowance balance. It writes off a specific customer balance of $1,100. What are the entry, ending allowance balance, and net receivables? (Answer: Debit allowance $1,100; credit accounts receivable $1,100; ending allowance credit balance $3,600; net receivables remain $46,500.)
Gross accounts receivable is $28,600, and the allowance has a $900 credit balance. A specific $1,400 customer balance is written off. What is the ending allowance balance and net receivables? Does the write-off record bad debt expense? (Answer: Allowance has a $500 debit balance; net receivables remain $27,700; no bad debt expense is recorded.)
Before two write-offs, gross accounts receivable is $96,000 and the allowance has a $7,500 credit balance. The company writes off balances of $2,250 and $1,750. Find ending gross receivables, the allowance balance, and net receivables. (Answer: Gross receivables $92,000; allowance credit balance $3,500; net receivables $88,500, unchanged.)
A clerk debits bad debt expense and credits accounts receivable for a specific $840 balance under the allowance method. State the correction and the effect of the correct entry on total assets and bad debt expense at the write-off date. (Answer: Replace the entry with a debit to the allowance and a credit to accounts receivable for $840; total assets and bad debt expense are unchanged.)
Immediately before a $2,600 write-off, gross receivables are $40,100 and the allowance has a $1,300 credit balance. Calculate net receivables before and after the entry, including the signed allowance balance after the write-off. (Answer: Net receivables are $38,800 both before and after; afterward gross receivables are $37,500 and the allowance has a $1,300 debit balance.)
