Is Bad Debt Tax Deductible? Requirements, Proof, and Reporting

Bad debt is tax deductible under federal law when a real loan or previously reported income becomes uncollectible, but the rules split sharply between business and personal debts. Business bad debts come off your ordinary income. Personal bad debts are treated as short-term capital losses, which caps how much you can write off against ordinary income each year.¹

Three Requirements Every Bad Debt Must Meet

Before the type of debt matters, the debt itself has to clear three tests.

It has to be a real debt. A bona fide debt comes from an enforceable obligation to repay a specific sum of money.² Both sides had to understand, when the money changed hands, that it was a loan and not a gift. Without a written agreement or comparable evidence that repayment was expected, the IRS can recharacterize the transfer as a gift, and gifts are not deductible.³

You have to have money at stake. The deduction is limited to your basis in the debt: cash you actually loaned, or an amount you already reported as income on a prior return. Cash-method taxpayers, which covers most individuals, cannot deduct unpaid wages, rent, fees, or interest that were never picked up as income in the first place.³ A landlord who never reported the missing rent has nothing to deduct. An accrual-method business, which records income when earned, can deduct receivables that go unpaid.

The debt has to be worthless. Worthlessness is a facts-and-circumstances question: there must be no reasonable expectation of repayment, and you must have taken reasonable steps to collect. You do not have to sue, and you do not have to wait for the payment due date if the debtor has clearly become unable to pay.³

Business Bad Debts Get Better Treatment

A business bad debt is one created or acquired in your trade or business, or one that became worthless in the course of business operations. Unpaid customer invoices, loans to suppliers or employees, and payments you made as a guarantor on a business loan all qualify, provided your primary motive was business-related.³

Two advantages come with that classification. Business bad debts are ordinary losses, reducing regular income directly rather than being trapped by the capital loss cap.¹ And a business debt does not have to be entirely worthless before you write it off. You can deduct a partially worthless business debt in the year you formally charge off the uncollectible portion on your books, with the deduction capped at the amount charged off.⁴ You are not required to charge off partial worthlessness every year, but once the whole debt is totally worthless, that year is your last chance.

Personal Bad Debts Are Capital Losses

Any deductible bad debt that is not a business debt is a nonbusiness bad debt. The classic case is a personal loan to a friend or family member. Two rules make these deductions less generous.

A nonbusiness debt must be completely worthless before you can deduct anything. Partial worthlessness gets you nothing. And when you do deduct, the loss is treated as a short-term capital loss no matter how long the loan was outstanding.¹

Because it is a capital loss, it runs through the annual capital loss ceiling. It offsets any capital gains you have for the year, plus up to $3,000 of ordinary income ($1,500 if married filing separately).⁵ Anything left over carries forward to future tax years and keeps carrying forward until it is used up.⁶ Loan a friend $15,000 that goes bad in a year with no capital gains, and you deduct $3,000 that year against ordinary income and carry the remaining $12,000 forward.

Loans to Family Members

Family loans draw extra IRS scrutiny because the line between a loan and a gift is often thin. If you lend money to a relative with an unspoken understanding that repayment is optional, the transfer is a gift, and no bad debt deduction is available later.³ To keep the option open, structure the loan the way you would with anyone else.

Federal law also requires loans between related parties to charge at least the Applicable Federal Rate (AFR), which the IRS publishes monthly and which varies by loan term. Charging less than the AFR causes the uncharged interest to be treated as a taxable gift from you to the borrower. There is a small-loan exception: if total outstanding loans between you and one individual stay at or below $10,000, the below-market interest rules do not apply, unless the borrower uses the money to buy income-producing assets like stocks or rental property.⁷

Practically, that means a signed written agreement with the loan amount, a fixed repayment schedule, and an interest rate at or above the current AFR. Keep bank statements or canceled checks proving the money moved. Save texts, emails, and letters about repayment. If the borrower falls behind, document what you did about it before writing the debt off.

Proving the Debt Is Worthless

The IRS will not take your word for it. You need facts showing no reasonable chance of repayment. Evidence that carries weight includes:

A bankruptcy discharge covering the debtor, which is among the clearest signs the debt cannot be recovered.
Failed collection efforts: demand letters, phone logs, communications with a collection agency showing the debtor is unresponsive or unable to pay.
Proof the debtor has no assets, income, or other resources, such as court records showing unsatisfied judgments from other creditors.
A reasoned conclusion that suing would not produce a collectible judgment, even without actually filing suit.³

Claim the deduction in the year the debt became worthless, not earlier and not later. If the right year turns out to be a prior one, you can amend that return under an extended deadline described below.

How to Report It on Your Return

The form depends on the type of debt.

Sole proprietors report a business bad debt on Schedule C (Form 1040) as an “Other Expense” in Part V, described as a bad debt.⁸ Partnerships and corporations report the deduction on their own returns.³

Nonbusiness bad debts go on Form 8949, Part I, line 1, as short-term capital losses. In column (a), enter the debtor’s name and write “bad debt statement attached.” Enter zero in column (d) and your basis (the amount you loaned) in column (e). Use a separate line for each debt. The totals flow to Schedule D of your Form 1040.³ Attach a statement to your return that describes the debt and amount, the due date, the debtor’s name and any business or family relationship to you, the steps you took to collect, and why you concluded the debt was worthless.⁹

If the Debtor Later Pays

Recover money on a debt you already deducted, and you generally report the recovery as income in the year you receive it. Under the tax benefit rule, you owe tax on the recovery only to the extent the original deduction actually reduced your tax.¹⁰ For a partially worthless business debt that was charged off, any portion never deducted comes back first and is not taxable.¹¹

Seven Years to Claim a Missed Bad Debt

The usual three-year deadline for amending a return does not apply to bad debts. If you missed a deduction and need a refund, you have seven years from the due date of the return for the year the debt became worthless.¹² The extended window also covers refunds tied to a net operating loss carryback caused by the bad debt. Keep loan documents, correspondence, and collection records for at least seven years after the debt goes bad so you can back up the claim if the IRS looks at it.
