If you've researched short sales at any point in the last decade and a half, you probably came across a reassuring line: forgiven mortgage debt on your primary residence isn't taxed.

That was true. It is no longer automatically true, and almost nobody is talking about it.

The qualified principal residence indebtedness exclusion — the provision that kept forgiven mortgage debt off homeowners' tax returns since 2007 — expired for debt discharged after December 31, 2025.

This is the most significant change to the short sale landscape in years, and it deserves a clear-eyed explanation rather than alarm. So in this post we'll walk through what the exclusion did, what exactly changed, what protections still exist (there are several, and they're meaningful), and what it means for the decision in front of you. We'll also be direct about the limits of our expertise here: we sell real estate, we don't prepare taxes, and this is a post that should end with you calling a CPA. Tax questions should ALWAYS go to the professional!

Let’s start with the underlying tax rule, because it surprises people.

When a lender forgives debt you owed, the IRS generally treats the forgiven amount as income to you. The logic is that you received something of value — money you borrowed and no longer have to repay. It's reported to you and to the IRS on a Form 1099-C, Cancellation of Debt.

Applied to housing, that rule produced a harsh result. A family that lost a home and walked away with nothing could receive a tax bill on tens of thousands of dollars of "income" they never saw.

Congress responded in 2007, at the front edge of the housing crisis, by creating an exclusion for qualified principal residence indebtedness — mortgage debt used to buy, build, or substantially improve your main home. If forgiven debt fit that definition, you could exclude it from income.

The exclusion was never permanent. It was written with an expiration date and extended repeatedly — sometimes retroactively, after it had already lapsed. The most recent extension carried it through the end of 2025 and set the cap at $750,000 ($375,000 if married filing separately), down from the original $2 million.

That extension has now run out.

Debt discharged before January 1, 2026 can still qualify under the old rules.

Debt discharged on or after January 1, 2026 does not qualify for this particular exclusion.

There's one important transition provision worth knowing: the exclusion can still apply where a written agreement was entered into before January 1, 2026, even if the actual discharge happens afterward. If your short sale was negotiated and agreed in writing in 2025 but closed this year, that timing detail could matter a great deal to your return. Bring the dated paperwork to your tax preparer.

For a short sale negotiated and closed in 2026, though, the plain answer is that this exclusion is not available.

Suppose a Utah homeowner owes $460,000, the home sells for $400,000, and the lender approves the short sale and forgives the $60,000 shortfall.

Under the old rules, that $60,000 was generally excludable, and the homeowner reported nothing.

Under the current rules, that $60,000 is potentially taxable income — reported on a 1099-C, added to the homeowner's income for the year, and taxed at their marginal rate. Because Utah's individual income tax calculation begins from federal figures, an amount included federally will generally flow through to the state return as well. The combined bill on $60,000 is not a rounding error.

Unless one of the remaining exclusions applies. And for a lot of people in this situation, one does.

This is the part that got lost in the headline, and it's the part that matters most for the homeowners we actually work with.

This is the big one, and it fits a striking number of short sale sellers.

If, immediately before the debt is forgiven, your total liabilities exceed the fair market value of your total assets, you are insolvent for tax purposes — and forgiven debt is excludable to the extent of that insolvency.

Read that carefully, because the mechanics matter. It's not all-or-nothing. If your debts exceed your assets by $45,000 and $60,000 is forgiven, you'd generally exclude $45,000 and include $15,000.

The calculation counts everything: the mortgage itself, credit cards, auto loans, student loans, medical debt, tax debt, and even certain contingent liabilities on the debt side; your home, vehicles, bank accounts, retirement accounts, and personal property on the asset side. Retirement accounts count as assets, which surprises people and can flip the result.

Someone underwater enough on their home to need a short sale is frequently insolvent on paper. The IRS publishes an insolvency worksheet in Publication 4681, and this is precisely the kind of calculation a CPA should run — with documentation retained, because it's the taxpayer's burden to establish.

Debt discharged in a Title 11 bankruptcy case is generally excluded from income. If bankruptcy is already part of your picture, this interacts with everything above and is a conversation for a bankruptcy attorney and a CPA together.

If the loan is genuinely non-recourse — meaning the lender's only remedy is the property and you're not personally liable — forgiveness generally doesn't produce cancellation-of-debt income at all. It's handled differently, as part of calculating gain or loss on the disposition. Whether a particular Utah loan is recourse or non-recourse depends on the loan documents and the circumstances, and it's not something to assume from the outside.

Here's a point worth sitting with: cancellation-of-debt income only arises if debt is actually cancelled. If a lender pursues you for the deficiency rather than forgiving it, there's no forgiveness to tax — you simply still owe the money, which is decidedly worse. Negotiating a release of the deficiency remains the goal in a well-handled short sale. This change affects the tax treatment of that release, not whether you should want it.

Because it would be easy to read this post and draw the wrong conclusion, let's be clear about what still holds:

A short sale is still generally better than a foreclosure. Consider that a foreclosure can also produce forgiven debt and a 1099-C — with worse credit consequences, less control, and no opportunity to negotiate the terms. The tax rules changed for everyone at once; they didn't change the comparison between the alternatives.

Deficiency protections under Utah law are unchanged. After a trustee's sale in Utah, a lender has a limited window — three months — to sue for a deficiency, and the amount is capped with reference to the property's fair market value. That's separate from federal tax law and unaffected by this expiration.

The insolvency exclusion is not a loophole. It's a longstanding provision of the tax code that has always been there, sitting behind the residence exclusion. For many years it simply wasn't needed for homeowners. Now it is, and for a substantial share of distressed sellers it does similar work.

Congress could extend it again. This provision has lapsed and been revived retroactively more than once in its history. We're not going to predict whether that happens, and you shouldn't plan on it — but if you're doing a short sale this year, it's a reason to keep clean records and to have your preparer watch for late-year legislation. A good piece of advice here is to remain in communication with your tax preparer for the most up to date information as things can and do change.

If you're considering a short sale in 2026, add one step to your process: talk to a CPA before you close, not in April. Ask specifically about the insolvency calculation and whether you'd qualify. Knowing whether you're facing a tax bill of $0 or $15,000 changes how you plan, and it's information you can have in advance.

If your short sale closed in 2025 or was agreed in writing before January 1, 2026, dig out the dated approval letter and closing statement. That timing may put you under the old rules.

If you're weighing a short sale against doing nothing, this change is a reason to move sooner rather than later — not to freeze. Time is what creates options here: time to get a tax opinion, time to negotiate deficiency language, time to sell into a decent market rather than a foreclosure timeline.

If you're already in a short sale with us, we'll flag this in your file and make sure it's on your radar before closing. Anyone doing this work responsibly in 2026 should be raising it with you unprompted. You should make sure to put us in contact with your CPA to make sure we are evaluating all options.

No. It means the automatic exclusion for primary residences is gone and you now need to qualify under a different provision — most commonly insolvency, which fits a lot of people in this situation. The answer is specific to your finances, and a CPA can tell you before you commit.

Add up all your liabilities and the fair market value of all your assets — including retirement accounts — as of immediately before the debt is forgiven. If liabilities are higher, you're insolvent by that difference, and that difference sets the amount you can exclude. IRS Publication 4681 has the worksheet. Have a professional review it.

It's the form a lender files to report cancelled debt, generally issued for the tax year in which the debt is discharged and sent to you in early the following year. Receiving one doesn't automatically mean you owe tax; it means the amount has to be addressed on your return, whether that's by including it or by claiming an exclusion.

No — and this is worth stating plainly. Foreclosure can generate cancelled debt and a 1099-C too, while costing you more in credit damage, control, and the ability to buy again. There's no tax advantage hiding in a foreclosure.

Utah's individual income tax calculation starts from federal figures, so an amount included in federal income will generally carry into the state return. The specifics depend on your full return — ask your preparer to walk you through both.

No, and you should be wary of any real estate professional who says they can. We can tell you what a short sale will look like, what we expect to negotiate on the deficiency, and roughly what shortfall might be forgiven. Turning that into a tax number is a CPA's job, and we're glad to work alongside yours.

For eighteen years, the tax question in a short sale had a comfortable default answer. It doesn't anymore — and a homeowner who closes in 2026 assuming the old rule could be in for a genuinely unpleasant surprise next spring.

But this is a change to plan around, not to be paralyzed by. The insolvency exclusion is real and it covers a lot of ground. The deficiency is still negotiable. And every reason a short sale beat a foreclosure last year still holds today.

What's different is that the conversation now needs a CPA in it, early. If you're a Utah homeowner thinking about a short sale, let's look at your situation together — the numbers, the timeline, and what to ask your tax professional before you sign anything. If you don't have one, we're happy to point you toward people who handle this well.

Zero pressure and zero judgment. A conversation costs nothing, and it could change everything.
