A bad debt is an amount that is written off by the business as a loss to the business and classified as an expense because the debt owed to the business is unable to be collected, and all reasonable efforts have been exhausted to collect the amount owed. This usually occurs when the debtor has declared bankruptcy or the cost of pursuing further action in an attempt to collect the debt exceeds the debt itself.

The debt is immediately written off by crediting the debtor's account and therefore eliminating any balance remaining in that account. A bad debt represents money lost by a business which is why it is regarded as an expense.

Doubtful debts are those debts which a business or individual is unlikely to be able to collect. The reasons for potential non payment can include disputes over supply, delivery, and conditions of goods or the appearance of financial stress within a customer's operations. When such a dispute occurs it is prudent to add this debt or portion thereof to the doubtful debt reserve. This is done to avoid over-stating the assets of the business as trade debtors is reported net of Doubtful debt. When there is no longer any doubt that a debt is uncollectible the debt becomes bad. An example of a debt becoming uncollectible would be:- once final payments have been made from the liquidation of a customer's limited liability company, no further action can be taken.

Bad or BAD may refer to:

A debt is an obligation owed by one party (the debtor) to a second party, the creditor; usually this refers to assets granted by the creditor to the debtor, but the term can also be used metaphorically to cover moral obligations and other interactions not based on economic value.

A debt is created when a creditor agrees to lend a sum of assets to a debtor. Debt is usually granted with expected repayment; in modern society, in most cases, this includes repayment of the original sum, plus interest.

In finance, debt is a means of using anticipated future purchasing power in the present before it has actually been earned. Some companies and corporations use debt as a part of their overall corporate finance strategy.

The word comes from the French dette and ultimately Latin debere (to owe), from de habere (to have). The letter b in the word debt was reintroduced in the 18th century, possibly by Samuel Johnson in his Dictionary of 1755 – several other words that had existed without a b had them reinserted at around that time.
