You can claim a capital loss on inherited property, but only if you treated it as an investment rather than a personal residence and then sold it for less than its stepped-up basis. Move in, store your things there, or use it as a vacation house, and the loss becomes nondeductible. That single distinction decides the outcome for most heirs.
The Stepped-Up Basis Is Your Starting Point
When you inherit real estate, your cost basis is not what the deceased paid. It resets to the property’s fair market value on the date of death.1Office of the Law Revision Counsel. 26 USC 1014 – Basis of Property Acquired From a Decedent If a parent bought a house for $40,000 in 1985 and it was worth $350,000 the day they died, your basis is $350,000. Every dollar of appreciation during their lifetime disappears from the tax books.
A loss becomes possible only when the sale price comes in below that date-of-death value. Inherit a home with a $350,000 basis, sell it eighteen months later for $310,000, and the $40,000 gap is your potential capital loss. Whether you can actually deduct it depends on what you did with the property in between.
Stepped-Down Basis
The rule cuts both ways. If the decedent paid $400,000 for a home worth only $280,000 at death, your basis is $280,000, not $400,000.2eCFR. 26 CFR 1.1014-1 – Basis of Property Acquired From a Decedent The $120,000 decline during their lifetime is gone. Nobody deducts it. You can claim a loss only on further decline below $280,000 after you inherit.
Alternate Valuation Date
If asset values dropped in the six months after death, the executor may elect to value the estate as of six months later instead.3Office of the Law Revision Counsel. 26 USC 2032 – Alternate Valuation That election reduces estate tax, but it also lowers your stepped-up basis, so you need a bigger post-valuation price drop before there is a deductible loss. The executor can only elect it if it reduces both the gross estate and the total estate tax, and the choice cannot be reversed.
Personal Use Kills the Deduction
Federal tax law lets individuals deduct losses only from a trade or business, a transaction entered into for profit, or certain casualty events.4Office of the Law Revision Counsel. 26 USC 165 – Losses A loss on selling your own home fits none of those categories, and the IRS says so directly: a loss on the sale of a main home is not deductible.5Internal Revenue Service. Tax Considerations When Selling a Home
Inherited property follows the same logic. Move in, store belongings there, use it as a getaway, and you have converted it to personal use. The loss vanishes for tax purposes. Even a few months of personal occupancy while you decide what to do can reclassify the property.
To preserve the deduction, treat the property as an investment asset from day one. List it for sale or for rent promptly. Do not use it yourself. Keep it vacant if the sale takes time, and document that it was continuously marketed. A signed listing agreement, correspondence with prospective buyers or tenants, and utility records consistent with an unoccupied home all support investment intent if the IRS questions the return.
The Holding Period Is Automatically Long-Term
No matter how quickly you sell after inheriting, the property is treated as held for more than one year.6Office of the Law Revision Counsel. 26 USC 1223 – Holding Period of Property Close the sale five days after the death and it still counts as a long-term capital loss. That matters at tax time: long-term losses first offset long-term capital gains, then short-term gains, and only then reduce ordinary income.
Calculating the Loss
Your loss equals the difference between your adjusted basis and your net sale proceeds. Adjusted basis starts with the date-of-death fair market value, plus any capital improvements you made while owning the property, such as a new roof or HVAC system. Routine maintenance and cosmetic repairs do not count.7Internal Revenue Service. Publication 551 – Basis of Assets
Net proceeds are the sale price minus selling costs. Real estate commissions, title insurance, transfer taxes, and closing attorney fees all reduce the amount realized, which enlarges your loss. Inherit a home with a $350,000 basis, spend $15,000 on a new roof, and sell for $330,000 after $20,000 in commissions and closing costs, and your $365,000 adjusted basis against $310,000 net proceeds produces a $55,000 capital loss.
Get an Appraisal
You need a professional appraisal establishing fair market value as of the date of death.8Internal Revenue Service. Gifts and Inheritances Do not wait years. Appraisers can work retroactively using comparable sales data, but the further out you go, the harder the number is to defend. A standard single-family appraisal typically runs a few hundred dollars, which is cheap insurance for a much larger tax benefit.
Reporting the Loss
Report the sale on Form 8949, entering the date-of-death value as your basis and the sale price as your proceeds. The result flows to Schedule D of your Form 1040, where it combines with your other capital gains and losses for the year.8Internal Revenue Service. Gifts and Inheritances
If you have capital gains from other investments, the inherited-property loss offsets them dollar for dollar. When total losses exceed total gains, you can deduct up to $3,000 of the excess against ordinary income, or $1,500 if married filing separately.9Office of the Law Revision Counsel. 26 USC 1211 – Limitation on Capital Losses That cap has not moved since 1978, so a large loss takes years to fully absorb.
Anything unused carries forward indefinitely. Each future year, apply the same order: offset capital gains, deduct up to $3,000 against ordinary income, carry the rest forward. Heirs with large losses often look for capital gains elsewhere in their portfolio to accelerate the benefit.
Sales to Family Members Get No Deduction
Sell the inherited property to a sibling, parent, child, grandchild, or spouse, and federal law disallows the loss entirely.10Office of the Law Revision Counsel. 26 USC 267 – Losses, Expenses, and Interest With Respect to Transactions Between Related Taxpayers Family for this purpose includes brothers and sisters (including half-siblings), spouses, ancestors, and lineal descendants. A genuine fair market price does not save the deduction.
One partial offset: if the family buyer later sells to an unrelated party at a gain, they can reduce that gain by the amount of your disallowed loss. The benefit shifts to them and only materializes if they eventually sell at a profit.
When the Estate Sells Instead
Sometimes the estate sells the property before distributing anything. In that case the estate reports the gain or loss on Schedule D of Form 1041, the estate income tax return, and the same $3,000 annual cap on net capital losses applies.11Internal Revenue Service. 2025 Instructions for Form 1041 and Schedules A, B, G, J, and K-1
If the estate still has an unused capital loss carryover when it terminates, the carryover passes through to the beneficiaries on Schedule K-1. You then continue the loss on your own return under the standard rules. This pass-through happens only on the estate’s final return, so if the estate stays open for years without enough gains to absorb the loss, the benefit is delayed until the estate formally closes.
