A Form 1099-C, Cancellation of Debt, tells the IRS that a lender forgave or stopped pursuing money you owed. The IRS computer then expects to see that amount as income on your return. When the form is right, that is usually a fair result, because forgiven debt is generally taxable unless an exclusion applies. When the form is wrong, the computer does not know the difference, and you can end up with a tax bill for income you never had.
Errors on these forms are more common than most people expect. Creditors file them in volume, often years after the underlying event, and often after the debt has been sold one or more times. Before you report a 1099-C as income, or pay an IRS notice based on one, it is worth spending an hour checking whether the form describes something that actually happened.
Creditors do not file a 1099-C because they feel like it. Treasury regulations require them to file after an "identifiable event," and Box 6 tells you which event the creditor is claiming. According to the IRS instructions for Forms 1099-A and 1099-C, the codes are:
Codes A, B, D, E, and F usually point to a document you can find: a bankruptcy discharge order, a court judgment, a settlement letter. Code G is different. It rests entirely on the creditor's own internal decision, and it is the code most often attached to forms that surprise people.
Code G applies when a creditor decides to end collection and discharge the debt, or follows a policy that does so. The regulation deems the debt canceled "solely" for reporting purposes. That phrasing matters. Whether you actually have taxable income is a separate question governed by the income tax rules, not by what the creditor chose to report.
In practice, a code G form can show up when:
An accounting charge-off is not the same as forgiving a debt. If the creditor or a later buyer can still sue you, or is still sending collection letters, there may be no discharge at all. Courts have also held that the year of discharge is the year it became clear the debt would never be paid, which may be different from the year printed on the form. The Tax Court applied that idea in Cozzi v. Commissioner, 88 T.C. 435 (1987), and refused to let the form's year control in Clark v. Commissioner, T.C. Memo. 2015-175.
1. No real cancellation. Look for evidence that collection continued after the date in Box 1: letters from a collection agency, lawsuit threats, a sale of the account to another company. Any of these can undercut the claim that the debt was discharged.
2. The wrong amount. For lending transactions, creditors are only required to report stated principal. Interest can be included in Box 2, but if it is, it must also be shown in Box 3. Late charges, collection costs, and similar items are not required to be reported for a loan. If Box 2 looks high, request the full payment history and charge-off records and compare the forgiven principal with what was reported.
3. The wrong year. Canceled debt belongs in the tax year when the discharge really occurred. A short sale closing in late December can generate a form dated the next year because of when a creditor's system processed the write-off. If the real discharge happened in an earlier year, and especially in a year now closed by the statute of limitations, the difference can be decisive. Gather the closing statement, settlement letter, and any correspondence that shows when collection really ended.
4. Duplicate or joint-debtor forms. After a lender sells a written-off account, both the original lender and the buyer may file forms for the same debt. Separately, for a jointly owed debt of $10,000 or more incurred after 1994, the creditor must report the entire canceled amount on each co-debtor's form. That reporting rule does not decide how much income each person actually has. Co-borrowers each need to address their own share, insolvency, and facts.
5. Debt you never owed. IRS instructions tell creditors not to file a 1099-C when fraudulent debt is canceled because of identity theft. If the account was opened in your name without your consent, keep your identity theft report and the creditor's fraud determination. Those documents are your answer.
Only the company that filed the form can correct it, and the right person is rarely in customer service. A few tips make a correction request more likely to work:
Do not count on a lawsuit against the creditor as leverage. The federal damages remedy for fraudulent information returns, I.R.C. § 7434, has been held not to cover a Form 1099-C by the Seventh Circuit, and that is not a fight worth leading with.
Many creditors do not respond, and some refuse. The form then stays on file with the IRS, and the job shifts to your own return. That usually means one of two approaches:
Either way, keep in mind that the IRS matching system compares the 1099-C to your return line by line. If nothing on the return addresses the form, a notice is likely. Addressing it on the return, with an explanation, is better than leaving the computer to draw its own conclusion.
Forms for a given year generally reach debtors early in the following year. Mortgage forgiveness relief for qualified principal residence debt expired at the end of 2025, according to the IRS instructions, so 2026 short sales and foreclosures may produce more taxable forms than in prior years. If you settled, short sold, or walked away from a debt this year, start collecting the paperwork now, while the people and records are easy to reach.
Suppose a hypothetical client receives a 1099-C coded G for $41,000 on a credit card he stopped paying years ago. His records show the bank sold the account to a debt buyer, which sent collection letters as recently as last spring. The $41,000 also includes several years of interest and late charges. His representative writes to the debt buyer's tax department with the sale notice and the recent collection letters and asks that the form be withdrawn. When no answer comes, the return reports no cancellation income for that account, with a Form 8275 explaining why, and the file is ready if the IRS follows up.
