Is Forgiven Mortgage Debt Taxable? What Changed in 2026

By the NFPGRP Team · Published · Updated

If a lender has agreed to forgive part of your mortgage debt, whether through a loan modification, a short sale, a deed-in-lieu, or foreclosure itself, it can feel like real relief. Then a tax form arrives, and a new worry sets in: does the IRS treat forgiven debt as income you now owe tax on? Sometimes it does, and a major federal tax break for forgiven mortgage debt largely ended after 2025. This article explains what “cancellation of debt” income means in plain terms, what changed in 2026, and why the real answer for your own return has to come from a tax professional or the IRS, not a blog post.

What “Cancellation of Debt” Income Actually Means

Borrowing money isn't income, because you owe it back. But when a lender later cancels or forgives some of that debt, meaning you no longer have to repay it, the IRS generally treats the forgiven amount as if it were money you received. This is called “cancellation of debt” income, or COD income, and it can apply to a mortgage, a credit card, a car loan, or other debts.

For homeowners going through foreclosure, this can show up more than one way: a lender writing off the balance left after a short sale, a reduced principal balance from a loan modification, or a deficiency balance forgiven after a foreclosure sale. When a lender cancels a qualifying amount of debt, they generally have to send you, and the IRS, a form called a 1099-C, “Cancellation of Debt.” Getting one doesn't automatically mean you owe tax on it, but it doesn't mean you're in the clear either. It means it's time to look closer.

Why Forgiven Mortgage Debt Has Its Own History in Tax Law

Because cancelled mortgage debt can involve a large number, and tends to hit at the exact moment someone is already in a financial crisis, it's gotten specific legislative attention over the years. At various points, lawmakers have created tax exclusions for forgiven mortgage debt on a primary home, so that under the right conditions, some or all of it wouldn't be taxed.

These exclusions have never been a permanent feature of the tax code. The main one, usually called the qualified principal residence indebtedness exclusion, first passed in 2007 and was extended by Congress many times, with the fine print changing along the way. A rule that applied a few years ago, or something you read online, may not apply to your situation now.

What Changed in 2026

As of this update, that federal exclusion ended for most mortgage debt forgiven after December 31, 2025. Through 2025, it let homeowners exclude up to $750,000 of forgiven debt on their main home ($375,000 if married filing separately) from federal taxable income.

There is one important exception for 2026: debt forgiven this year can still qualify if the cancellation comes from an arrangement, like a loan modification, short sale, or workout agreement, that was entered into and put in writing before January 1, 2026. If you signed something with your lender in 2025, keep a copy. It may matter at tax time.

Congress has revived this exclusion after it lapsed before, sometimes retroactively, and a bill to make it permanent has been introduced. So treat this as the rule as it stands today, not the final word, and check current IRS guidance (IRS Publication 4681 covers canceled debts and foreclosures) or ask a tax professional before you file.

We want to be upfront about that limit: NFPGRP is an educational platform, not a law firm or a tax preparation service. Nothing here is legal or tax advice, and reading it doesn't create a professional relationship with us. For a real answer about your own return, that has to come from a licensed tax professional or from the IRS directly.

Other Exceptions That Sometimes Apply

Even when a mortgage-specific exclusion isn't available, tax law has a couple of broader, longer-standing ideas that can sometimes reduce or eliminate cancellation of debt income, though applying them takes real calculation with your own numbers:

  • Insolvency: if your total debts were worth more than your total assets right before the cancellation, some or all of the forgiven amount may be excluded. Figuring this out means totaling everything you owed and owned at a specific point in time, not a rough guess.
  • Bankruptcy: debt cancelled as part of a bankruptcy case is generally treated differently than debt forgiven outside of one.

Getting this wrong, either assuming you owe tax you don't or assuming you're excluded when you're not, can be costly. This is exactly the kind of calculation a qualified tax professional is trained to walk through with you.

What to Actually Check Before You File

Instead of guessing, here's a grounded way to approach it:

  • Keep every 1099-C you receive, your loan paperwork, and records of what you owned and owed around the time the debt was cancelled.
  • Talk to a CPA, enrolled agent, or other qualified tax preparer who can review your specific numbers under the law that applies to the year you're filing for.
  • When in doubt, contact the IRS directly. Their current-year instructions reflect the law as it stands now, not as it stood whenever any article was written.
  • If your foreclosure is still in progress, a HUD-approved housing counselor can help you understand the overall timeline alongside, not instead of, the tax question.

An unexpected tax question on top of everything else can feel like one more thing stacked against you, but it's a solvable piece, not a sign things are falling apart. Once you know what your lender reported and what your own numbers look like, a tax professional can usually tell you fairly quickly where you stand. And if you're still working through the foreclosure itself, NFPGRP's other educational articles can help you understand the bigger picture while a licensed professional handles the parts that are specific to you.
