Short answer: in a short sale, you sell the home for less than you owe and the lender agrees to take the proceeds. In a deed in lieu of foreclosure, you sign the home over to the lender. Both mean leaving the home, both need the lender’s agreement, and both can leave a balance you still owe unless the lender waives it in writing. Canceled mortgage debt may be taxable: the federal exclusion for a main home covers only discharges before January 1, 2026, or under a written arrangement made before then. This page covers federal law only; other rules may apply where you live. It is general information, not legal, tax or financial advice.
At a glance
| Item | Short sale | Deed in lieu |
|---|---|---|
| What happens | You sell the home to a buyer for less than you owe, with the lender’s agreement | You voluntarily transfer ownership of the home to the lender |
| Who finds the buyer | You, through a sale | No buyer; the lender takes the home |
| Leftover balance (deficiency) | Ask the lender to waive it in writing | Ask the lender to confirm in writing that it covers the whole debt |
| Tax view (IRS Pub. 4681) | Canceled debt may be income | Treated as an exchange of the property to satisfy the debt; canceled debt may be income |
The CFPB says a short sale is a type of loss mitigation and an alternative to foreclosure, that because it is a sale you will have to leave your home, and that where you are responsible for any deficiency, you will want to ask the lender to waive it before the sale and get the waiver in writing (CFPB: short sale, last reviewed February 2, 2024, read October 30, 2026; this page may be out of date). It says a deed in lieu is an arrangement where you voluntarily turn over ownership of your home to the lender, that you should make sure it covers the entire amount you still owe, and that you may still owe tax (CFPB: deed in lieu, last reviewed January 2, 2025). For both, it suggests asking about help with moving costs, sometimes called “cash for keys”.
How the servicer must handle your application
Under Regulation X, a loss mitigation option is an alternative to foreclosure offered by the owner or assignee of the loan and made available through the servicer (12 CFR 1024.31, eCFR, text up to date as of October 28, 2026, read October 30, 2026). The official comments list short sales and deeds in lieu as examples, along with options to stay in the home such as a modification, repayment plan or forbearance (Supplement I, comment 31 (Loss mitigation option)-1, eCFR).
- If the servicer gets your application 45 days or more before a foreclosure sale, it must review it promptly and tell you in writing within 5 days (not counting legal public holidays, Saturdays and Sundays) whether it is complete, and if not, what is missing (12 CFR 1024.41(b)(2)(i)).
- If it gets a complete application more than 37 days before a foreclosure sale, it must, within 30 days, evaluate you for all loss mitigation options available to you and tell you in writing which ones, if any, it will offer (1024.41(c)(1)).
- If it denies a trial or permanent loan modification, the notice must give the specific reasons (1024.41(d)). That rule covers modifications only, not a short sale or deed in lieu.
- The rule does not require a servicer to offer any specific option (1024.41(a)).
Source: 12 CFR 1024.41 (eCFR, read October 30, 2026). The comments say that if you tell the servicer you would rather do a short sale, it may not stop collecting the documents it needs to review options to keep the home only because of that preference (comment 41(b)(1)-1.ii). Large servicers must also give you contact staff for loss mitigation; see your mortgage servicer’s point of contact and options when you are behind on mortgage payments.
Example: the shortfall
This example is only for the math, with example figures, not terms from any lender. You owe $320,000, the home is worth $280,000, and the example selling costs in the short sale are $16,800.
| Item | Short sale | Deed in lieu |
|---|---|---|
| Loan balance | $320,000 | $320,000 |
| Sale price or fair market value | $280,000 sale price | $280,000 fair market value |
| Paid to the lender | $280,000 − $16,800 = $263,200 | The home, worth $280,000 |
| Shortfall | $320,000 − $263,200 = $56,800 | $320,000 − $280,000 = $40,000 |
In this example, if the lender waives the shortfall in writing, that amount is canceled debt; if it does not, you may still owe it. The figures on your own Form 1099-C come from the lender.
The tax side
Canceled debt is generally income unless an exclusion applies. The exclusion for qualified principal residence indebtedness covers debt discharged before January 1, 2026, or under an arrangement entered into and evidenced in writing before January 1, 2026 (26 U.S.C. 108(a)(1)(E), LII, read October 30, 2026). IRS Publication 4681, for 2025 returns, says it cannot be used for discharges completed or discharge agreements entered into after December 31, 2025 (IRS). Where it applies, it covers debt used to buy, build or substantially improve your main home, up to $750,000 ($375,000 if married filing separately); it reduces the home’s basis; it does not apply to a discharge for services or for reasons not tied to the home’s value or your finances; and only the part of a canceled loan above any non-qualifying part is excluded (108(h)(1)-(4)). Other exclusions, such as insolvency or bankruptcy, may still apply (108(a)(1)(A)-(B)); see canceled loan debt and taxes.
Publication 4681 says that if you were personally liable for the debt (recourse debt), a foreclosure is treated as a sale, gain or loss is figured on the fair market value, and debt canceled above the fair market value may be ordinary income; that a deed in lieu is treated as an exchange of the property to satisfy the debt; and that a lender that cancels $600 or more of debt must send you Form 1099-C. If you were not personally liable (nonrecourse debt), the whole debt is treated as the amount realized instead. Ask a tax professional how this applies to you.
Questions to ask the servicer
- Which options are available on my loan, including ways to keep the home?
- Will you waive any deficiency, and will you put that in writing before I sign?
- Does a deed in lieu cover the entire amount I owe?
- Is there help with moving costs, and what are the conditions?
- How will you report the account to the credit reporting companies?
- Will you send a Form 1099-C, and for what amount?
Checklist
- Send a complete loss mitigation application as early as you can, and keep copies.
- Get the short sale terms, any deficiency waiver or deed in lieu agreement in writing.
- Keep the closing papers and any Form 1099-C or 1099-A.
- Talk to a tax professional before you file for the year the debt is canceled.
- If you are sued for a deficiency or face a foreclosure sale, talk to a lawyer.
