Allowance for Doubtful Accounts

The allowance for doubtful accounts is a contra-asset account that reduces gross accounts receivable to the amount the company expects to collect. It carries a credit balance, sits directly under receivables on the balance sheet, and moves with an estimate the controller makes every period. The offsetting debit goes to bad debt expense, so the estimate reaches the income statement in the same period as the sale it relates to.

Two methods produce the estimate. The percentage-of-sales method applies a historical loss rate to credit sales for the period. The aging method applies a rate to each bucket of the accounts receivable aging: a small rate to current balances, a larger rate to 61 to 90 days, a larger one again past 120 days. Most controllers use the aging method, because it tracks the balance sheet directly and responds when one large customer slips. Both rely on the company's own collection history. Under CECL, the estimate also has to reflect expected losses over the life of the receivable, adjusted for current conditions and reasonable forecasts, which pushes teams to document why a rate changed.

Three entries maintain the account. The period-end adjustment debits bad debt expense and credits the allowance. A write-off debits the allowance and credits the customer's receivable when a specific balance is judged uncollectible, which leaves net receivables and expense unchanged. A recovery reverses the write-off and then records the cash receipt through normal cash application. Writing off a balance against expense directly, with no allowance, is the direct write-off method. GAAP does not accept it for material receivables because it records the loss in a later period than the sale.

Auditors test the allowance by recomputing it. They ask for the aging at period end, the rates by bucket, the basis for each rate, and the subsequent cash receipts on the largest past-due balances. An estimate that moved without a documented reason is the finding. A reserve that tripled needs a named driver, such as a single customer bankruptcy, with the memo that supports it.

The allowance also ties to the rest of the close. The aging must reconcile to the receivables control account in the general ledger before any rate is applied, or the estimate rests on a wrong base. Slower DSO and weaker dunning follow-through push balances into older buckets and raise the required reserve. Misapplied cash overstates the past-due balances and inflates it.

The allowance is only as good as the aging beneath it. Adopt's agents tie the aging to the ledger each period, flag the customers whose balances moved buckets, and draft the reserve support for your reviewer to approve. Sign up free.
