What to Do If You Get a 1099-C for an Old Debt

A Form 1099-C for an old debt means a creditor reported to the IRS that it canceled $600 or more you owed, and the IRS now expects that amount on your return as ordinary income unless an exception or exclusion applies. The most common escape for someone blindsided by a years-old debt is the insolvency exclusion, which can wipe out the tax entirely if your debts exceeded your assets at the moment the cancellation happened. Before you do anything else, confirm the debt was really canceled, read the form carefully, and figure out which rule gets you off the hook.

Confirm the Debt Was Actually Canceled

A 1099-C in the mail does not always mean the creditor has given up its right to collect. The IRS warns that if a creditor keeps trying to collect after sending the form, the debt may not actually be canceled and you may not have income to report.¹ Creditors must file the form when an “identifiable event” happens, and one of those events is simply an internal decision to stop collection activity. That’s a reporting trigger, not a legal release.

On old debts, Box 6 usually shows Code G, meaning the creditor adopted a policy to stop pursuing you, or Code C, meaning the collection statute of limitations expired.² Either can arrive years after you last heard from the creditor, which is why these forms feel like they come out of nowhere. Call the creditor and ask, in writing, whether the balance is truly forgiven or whether they still consider it collectible. The answer affects both your tax return and whether you’ll keep hearing from collectors.

Read the Boxes That Decide What You Owe

A creditor files the form when it cancels $600 or more and an identifiable event has occurred, sending one copy to you and one to the IRS.³ Any gap between the form and your return gets flagged automatically.

Three boxes carry the weight:

Box 1 is the date of the identifiable event. That date sets the tax year you report the income, even when the underlying debt is much older. A 2025 event reported on a form you received in early 2026 belongs on your 2025 return.
Box 2 is the total canceled amount. This is what the IRS treats as income unless an exception or exclusion applies.
Box 6 is the reason code. Code A is bankruptcy, Code C is the expired collection statute, and Code G is the creditor’s decision to stop collecting.²

Box 3 reports any interest included in Box 2. Whether that interest piece is taxable depends on the type of debt: if the interest would have been deductible had you paid it, it’s not taxable when canceled; for ordinary consumer debts like credit cards, the interest stays in the taxable amount.

Check Whether an Exception Erases the Tax

Exceptions apply before exclusions and are simpler because they don’t require Form 982 or any reduction in future tax benefits.⁴ The ones most likely to apply to an old personal debt:

A gift. If a family member or friend forgave a personal loan as a gift, the canceled amount is not income to you; it falls under the gift tax rules instead.¹
Deductible debt. If you could have deducted the amount had you actually paid it, canceling it doesn’t create taxable income.
A purchase price reduction. If a seller later reduced what you owed on something you bought, that’s treated as a price adjustment, and your cost basis in the item goes down instead.

If one of these fits, you’re done with the tax question. If not, the next stop is the exclusion rules under Internal Revenue Code Section 108.

Work the Insolvency Exclusion

For most people hit with a 1099-C on old consumer debt, insolvency is the exclusion that does the real work. You qualify to the extent your total liabilities exceeded the fair market value of your total assets immediately before the cancellation.

The arithmetic is straightforward. Suppose your liabilities totaled $50,000 and your assets were worth $35,000 the moment before the debt was canceled. You were insolvent by $15,000. A $10,000 canceled debt is fully excluded. A $20,000 canceled debt is excluded up to $15,000, and the remaining $5,000 is taxable.

What counts as an asset is broader than people expect. The IRS includes retirement accounts like 401(k)s and IRAs, pension interests, the cash value of life insurance, and even household goods and clothing. The fact that creditors can’t reach a retirement account doesn’t keep it out of the insolvency test. On the liability side, include everything: credit cards, mortgages, car loans, medical bills, student loans, unpaid taxes, and judgments.⁵

Document the snapshot. The IRS can ask for proof of your financial picture as of the date in Box 1, so pull bank statements, loan balance printouts, property value estimates, and retirement account statements from around that date and keep them with your tax records.

If the debt was discharged in a Title 11 bankruptcy case instead, the entire amount is excluded with no cap, and the bankruptcy exclusion must be applied before any other.⁶ A Code A in Box 6 is the signal. You still file Form 982 to claim it.⁷

If the Form Is Wrong, Dispute It the Right Way

Contact the creditor first, not the IRS. Common errors include the wrong amount in Box 2, a form issued for a debt you already paid in full, or a cancellation date that doesn’t match reality. Gather settlement agreements, payoff confirmations, bank records, and any dispute correspondence, then ask in writing for a corrected form.

If the creditor refuses, file your return on time with the amounts you believe are accurate and attach a written statement explaining the discrepancy, the figure you think is correct, and what you did to try to get the form fixed. You’re responsible for reporting the correct taxable amount regardless of what the form says.¹ Having a paper trail already in the file works in your favor if the IRS follows up.

How to Report It on Your Return

The year that matters is the one in Box 1, not the year the debt originally arose. If no exception or exclusion applies, report the full Box 2 amount as ordinary income. For nonbusiness debt (credit cards, personal loans, medical bills), that goes on Schedule 1 (Form 1040), line 8c. Debt tied to a sole proprietorship goes on Schedule C, and farm debt on Schedule F.⁵

To claim any exclusion, attach Form 982.⁸ In Part I, check line 1a for bankruptcy or line 1b for insolvency outside of bankruptcy, and enter the excluded amount on line 2.⁷

The Trade-Off: Reducing Tax Attributes

Part II of Form 982 is where the government recovers some of what the exclusion gave you. When you exclude canceled debt, you must reduce certain tax benefits by the excluded amount, in a set order that starts with net operating losses and ends with foreign tax credit carryovers.⁹ For someone excluding an old credit card or medical balance, most of those categories are empty. The one that often matters is the basis in your property, because a lower basis can mean a larger taxable gain when you eventually sell.

What Happens If You Ignore It

Doing nothing is the worst option. The IRS already has the form, so a return that leaves the income off, or no return at all, generates an automatic mismatch notice. The IRS specifically lists failing to report income shown on a 1099 as an example of negligence.¹⁰

The accuracy-related penalty runs 20% of the underpaid tax and applies either for negligence or for substantial understatement, defined as understating tax by the greater of 10% of the correct tax or $5,000.¹⁰ Interest runs on top of the unpaid balance from the original due date. Qualifying for an exclusion doesn’t help if you never file Form 982 to claim it.

Time is not on your side if you’ve ignored a form from a prior year. The IRS normally has three years to assess additional tax, but that stretches to six years when unreported income exceeds 25% of what you reported, which a large canceled debt can easily trigger.¹¹ If you never filed a return for the year at all, there is no time limit. Filing an amended return with Form 982 attached, before the IRS contacts you, is almost always the better move and can reduce or avoid penalties.
