IRS Form 1099-A, Acquisition or Abandonment of Secured Property, is the form your lender sends after they foreclose on property that secured a loan or conclude that you’ve abandoned it. The form itself doesn’t calculate any tax. It gives you the numbers you’ll use to figure out whether the foreclosure produced a gain, a loss, or canceled debt you have to report as income. Two things determine your tax result: how your adjusted basis compares to what the IRS treats as your sale price, and whether the lender forgave any leftover balance.
When You Get One
A lender files Form 1099-A whenever they take possession of property securing a debt or have reason to believe you abandoned it.1Internal Revenue Service. Topic No. 432, Form 1099-A, Acquisition or Abandonment of Secured Property and Form 1099-C, Cancellation of Debt The property can be a home, a rental, commercial real estate, a vehicle, a boat, or anything else pledged as collateral. There is no minimum dollar threshold. The lender files regardless of loan balance or property value.2Internal Revenue Service. About Form 1099-A, Acquisition or Abandonment of Secured Property
The common triggers are foreclosure, a deed in lieu of foreclosure (where you hand the title back voluntarily), and formal abandonment. The date on the form controls which tax year you report the transaction in.
The Four Boxes That Matter
Four boxes on Form 1099-A drive the entire calculation.3Internal Revenue Service. Instructions for Forms 1099-A and 1099-C
- Box 1 is the date of acquisition or abandonment. It fixes the tax year and sets your holding period, which decides whether a gain is short-term or long-term.
- Box 2 is the balance of principal outstanding immediately before the lender took the property. If the debt was nonrecourse, this becomes your sale price. If it was recourse, it feeds into whether you have canceled debt.
- Box 4 is the property’s fair market value at the time. For recourse debt, this is treated as the sale price.
- Box 5 is the personal liability checkbox. Checked means recourse; unchecked means nonrecourse. That single box changes everything downstream.
Recourse vs. Nonrecourse Debt
Whether Box 5 is checked is the most consequential detail on the form. It decides which number counts as your sale price, and it decides whether canceled debt can even exist.4Internal Revenue Service. Publication 4681, Canceled Debts, Foreclosures, Repossessions, and Abandonments
Recourse Debt (Box 5 Checked)
When you’re personally liable, the IRS splits the foreclosure into two events. You’re treated as having sold the property for its fair market value (Box 4), and you compare that FMV to your adjusted basis to find gain or loss on the property itself. Separately, if the loan balance in Box 2 exceeds the FMV, the shortfall is either debt the lender will still pursue or debt the lender forgives. Forgiven debt is ordinary income, reported as cancellation of debt income.4Internal Revenue Service. Publication 4681, Canceled Debts, Foreclosures, Repossessions, and Abandonments
Say your home had an adjusted basis of $180,000, a fair market value of $150,000, and an outstanding loan of $200,000. You’d have a $30,000 loss on the property ($150,000 FMV minus $180,000 basis) and, if the lender forgives the shortfall, $50,000 of cancellation of debt income ($200,000 loan minus $150,000 FMV).
Nonrecourse Debt (Box 5 Unchecked)
When you’re not personally liable, the math is simpler and often produces a bigger reportable gain. The full outstanding loan balance in Box 2 is treated as the sale price, even if the property was worth much less. There is no separate canceled debt event because the lender never had the right to come after you personally for a shortfall.4Internal Revenue Service. Publication 4681, Canceled Debts, Foreclosures, Repossessions, and Abandonments
Using the same numbers with nonrecourse debt: the sale price is the full $200,000 loan balance, giving you a $20,000 gain over your $180,000 basis. No canceled debt income at all.
Calculating Gain or Loss
You need your adjusted basis either way. Start with what you paid for the property, add the cost of capital improvements (a new roof, an addition, a remodel), and subtract depreciation you claimed or should have claimed. That’s your adjusted basis.
Your gain or loss is the amount realized minus your adjusted basis. For recourse debt, the amount realized is Box 4 (FMV). For nonrecourse debt, it’s Box 2 (loan balance). A positive number is a gain. A negative number is a loss, though whether you can deduct it depends on how the property was used.
If you owned the property more than one year before the date in Box 1, a capital gain qualifies for long-term rates. One year or less means short-term, taxed at ordinary income rates.
Where to Report It on Your Return
Where the transaction goes depends on how you used the property.
- For personal-use property (your home, a vacation home, a personal vehicle): report on Form 8949 and carry totals to Schedule D of Form 1040.5Internal Revenue Service. Instructions for Form 8949
- For business or investment property (rental property, commercial real estate, business equipment): report on Form 4797, Sales of Business Property.6Internal Revenue Service. Instructions for Form 4797
If you also received a Form 1099-C for canceled debt, that amount goes on Schedule 1 of Form 1040, line 8c, regardless of what kind of property was involved.7Internal Revenue Service. Schedule 1 (Form 1040) – Additional Income and Adjustments to Income The property gain or loss and the canceled debt are reported in different places because the IRS treats them as separate transactions, even when they arise from the same foreclosure.
Losses on a Personal Home Can’t Be Deducted
This one surprises people. If you lost your personal home to foreclosure and the numbers show a loss, that loss is not deductible. The IRS doesn’t allow deductions for losses on property held for personal use, including abandonment losses.8Internal Revenue Service. Publication 544, Sales and Other Dispositions of Assets You still report the transaction on Form 8949 and Schedule D, but you enter the loss as zero.
Losses on business or investment property are different. Those are generally deductible and reported on Form 4797.
The Home Sale Exclusion Can Wipe Out a Gain
If the foreclosed property was your primary residence and the calculation produces a gain, the Section 121 exclusion may eliminate it. Single filers can exclude up to $250,000 of gain, and married couples filing jointly can exclude up to $500,000.9Office of the Law Revision Counsel. 26 USC 121 – Exclusion of Gain From Sale of Principal Residence
To qualify, you must have owned and lived in the home as your primary residence for at least two of the five years before the date in Box 1, and you can’t have used the exclusion on another sale within the past two years. For most homeowners whose properties didn’t appreciate dramatically, this eliminates the tax entirely.
1099-A Alone vs. 1099-A Plus 1099-C
Form 1099-A reports the property transfer. If the lender also forgives any remaining balance, they send a separate Form 1099-C for the canceled amount. Lenders must file a 1099-C when they forgive $600 or more of debt.10Internal Revenue Service. Instructions for Forms 1099-A and 1099-C
You might get a 1099-A with no 1099-C in two common situations: the debt was nonrecourse, so nothing was left to forgive, or the lender still plans to pursue you for the shortfall. Getting only a 1099-A doesn’t mean the debt issue is closed. The lender could forgive the balance years later and send a 1099-C then, which creates a taxable event in that future year. A lender can also combine both forms by filling in boxes 4, 5, and 7 of a single 1099-C, in which case no separate 1099-A arrives.3Internal Revenue Service. Instructions for Forms 1099-A and 1099-C
Canceled debt is taxable as ordinary income by default, but several exclusions may apply, including bankruptcy discharge, insolvency at the moment of cancellation, and qualified principal residence indebtedness. To claim any exclusion, you file Form 982 with your return.11Internal Revenue Service. Instructions for Form 982 The insolvency exclusion is worth checking even if you don’t think it applies. If your total liabilities exceeded the fair market value of all your assets immediately before the cancellation, you can exclude canceled debt up to the amount by which you were insolvent. Publication 4681 has a worksheet.4Internal Revenue Service. Publication 4681, Canceled Debts, Foreclosures, Repossessions, and Abandonments The qualified principal residence indebtedness exclusion covers up to $750,000 ($375,000 if married filing separately) of canceled mortgage debt on your main home, and applies to discharges before January 1, 2026, or to discharges under a written arrangement entered into before that date. Most of these exclusions require you to reduce other tax attributes (like the basis in remaining property) in exchange, so the benefit can shift the tax burden to a later year rather than erase it.
If the Form Is Wrong
Errors on Form 1099-A are not rare. The Box 4 fair market value is sometimes a rough estimate, and the Box 5 personal liability checkbox can be wrong if the lender didn’t carefully review the loan documents. Because these fields drive everything, a mistake can mean the difference between owing thousands and owing nothing.
Contact the lender first and ask for a corrected form. Send documentation supporting the right numbers: a recent appraisal, the original loan agreement, or the state law establishing whether the debt was recourse or nonrecourse. If the lender won’t issue a correction before your filing deadline, file on time using the figures you believe are accurate and attach a written explanation of the discrepancy.12Internal Revenue Service. What to Do When a W-2 or Form 1099 Is Missing or Incorrect If you can’t resolve the issue with the lender, call the IRS at 800-829-1040. The IRS can contact the lender and request a correction. Keep the original form, your correspondence, supporting documents, and a copy of any explanation you filed. Those records protect you if the IRS follows up.
