Business vs. Nonbusiness Bad Debts: Classification, Worthlessness, and Documentation

An amount that becomes uncollectible is not deductible merely because someone failed to pay. IRC §166 generally requires a bona fide debt arising from a valid debtor-creditor relationship and an enforceable obligation to repay a fixed or determinable amount. The taxpayer also generally needs tax basis in the debt.

Cash-Method Receivables Often Have No Deductible Basis

A cash-method service business generally has not included an unpaid customer invoice in income. If the customer never pays, there is usually no separate bad-debt deduction for the unreported receivable. Accrual-method receivables previously included in income may produce a deduction when the requirements are met.

Business Bad Debt

A business bad debt is created or acquired in the taxpayer's trade or business, or its loss is proximately related to that trade or business. For an individual's loan or guarantee connected to employment or investment, courts generally examine the taxpayer's dominant motivation—not simply whether the borrower was a business.

A wholly worthless business debt is generally an ordinary deduction. A partially worthless business debt may be deductible to the extent charged off during the year when the statutory and accounting requirements are satisfied. Banks and regulated entities may have special rules.

Nonbusiness Bad Debt

A noncorporate taxpayer's nonbusiness bad debt generally is treated as a short-term capital loss and is deductible only when the debt becomes wholly worthless. Capital-loss limitations and carryforward rules then apply.

Debt or Equity

Advances to an owner-controlled or thinly capitalized company may be equity rather than debt. Relevant facts include written terms, maturity, interest, repayment history, security, capitalization, ability to repay, creditor enforcement, and whether an unrelated lender would have made the advance. Worthless stock and partnership interests follow different rules.

Establishing Worthlessness

Worthlessness is determined from identifiable events and all facts known by year-end. Bankruptcy, insolvency, failed collection efforts, cessation of business, lack of assets, priority of other creditors, and settlement terms may be relevant. Bankruptcy filing does not automatically establish that every debt became worthless in that year.

A later recovery of an amount previously deducted may be taxable under the tax-benefit rule. Retain loan documents, payment history, collection correspondence, financial information, legal claims, charge-off records, and the analysis supporting the year of worthlessness.

Bad-debt treatment depends on the taxpayer, accounting method, basis, motivation, and collection facts. This information is educational and is not a conclusion that a particular advance or receivable is deductible.
