When you sell a deceased parent’s home, you usually owe little or no federal income tax on the sale, because the property’s tax basis resets to its fair market value on the date your parent died. You are taxed only on appreciation that happens after that date, and it is taxed at the lower long-term capital gains rates no matter how quickly you sell. The rest of this article walks through how that works, what documents you need, what the rates look like for 2026, and the situations that change the answer.
The Stepped-Up Basis Is Why Most Heirs Owe Little
Basis is the number the IRS uses to decide whether you made money on a sale. For most assets, basis is what the owner paid. Inherited property is different: the heir’s basis resets to the property’s fair market value on the date the owner died.1Office of the Law Revision Counsel. 26 USC 1014 – Basis of Property Acquired From a Decedent Your parent’s original purchase price drops out entirely.
An example makes the effect concrete. Say your parent bought the house for $80,000 in 1985 and it was worth $450,000 the day they died. Your basis is $450,000. Sell it for $455,000 and your taxable gain is $5,000, not $375,000. Decades of appreciation are wiped clean for tax purposes. This is the single most important rule to understand about selling an inherited home.
Any capital improvements you make after inheriting get added to your stepped-up basis and further reduce any gain.2Internal Revenue Service. Topic No. 703, Basis of Assets A new roof or a kitchen renovation counts. Routine maintenance and ordinary repairs do not. The test is whether the work adds value or extends useful life, versus simply keeping the home in its current condition.
You Have to Prove the Date-of-Death Value
The step-up only helps you if you can show what the home was worth on the specific day your parent died. That proof almost always comes from a formal appraisal by a qualified, independent professional. The appraiser values the property as of the date of death using standard methods such as comparable sales. Hire someone licensed and experienced with residential real estate in the local market; the IRS expects appraisers to have verifiable education and experience in valuing the type of property being appraised.
Keep the appraisal report together with a copy of the death certificate. The IRS can challenge your claimed basis years after the sale, and these documents are your defense. If the estate filed a federal estate tax return (Form 706), keep a copy of that too. Without documentation, the IRS may assign a lower basis and a larger gain.
Calculating the Gain
The math is simple: sale price, minus your stepped-up basis, minus selling expenses, equals your taxable gain or loss.
Selling expenses include real estate agent commissions, title insurance, attorney fees, transfer taxes, and recording fees. They are not deducted separately on your tax return. They shrink the gain itself, which is more valuable.
Holding costs are treated differently. Property taxes, insurance, and utility bills you paid between the date of death and the sale generally do not increase your basis and are not selling expenses. If you itemize, you can deduct property taxes paid during that period as part of your state and local tax deduction, subject to the $10,000 annual cap. Insurance and maintenance on a personal-use property are not deductible at all.
If the home sells for less than your stepped-up basis plus selling expenses, you have a capital loss. Losses first offset any other capital gains you had that year. If losses exceed gains, you can deduct up to $3,000 of the remainder against ordinary income ($1,500 if married filing separately), and carry any unused loss forward to future years.3Office of the Law Revision Counsel. 26 USC 1211 – Limitation on Capital Losses
The 2026 Rates on Whatever Gain You Do Have
Inherited property is always treated as a long-term capital gain, no matter how soon after the date of death you sell.4Internal Revenue Service. Topic No. 409, Capital Gains and Losses That matters, because long-term rates are lower than ordinary income rates. For 2026:
- 0% on taxable income up to $49,450 (single), $98,900 (married filing jointly), or $66,200 (head of household).
- 15% on taxable income up to $545,500 (single), $613,700 (married filing jointly), or $579,600 (head of household).
- 20% on taxable income above those thresholds.
These rates apply to the gain, not to the full sale price. An heir who sells two years after inheriting for $50,000 above the stepped-up basis owes tax only on that $50,000 of post-death appreciation, minus selling costs.
A separate 3.8% surtax, the Net Investment Income Tax, can apply on top of the capital gains rate when modified adjusted gross income exceeds $200,000 (single) or $250,000 (married filing jointly).5Internal Revenue Service. Topic No. 559, Net Investment Income Tax Gain on inherited property counts as net investment income. Stacked with the 20% top rate, the maximum effective federal rate is 23.8%. Most heirs are well below that ceiling.
If You Lived in the House Before Selling
If you moved into the inherited home and used it as your primary residence, an additional exclusion may apply. You can exclude up to $250,000 of gain, or $500,000 if married filing jointly, from the sale of your principal residence if you owned and lived in the home for at least two of the five years before the sale.6Office of the Law Revision Counsel. 26 USC 121 – Exclusion of Gain From Sale of Principal Residence
This exclusion stacks on top of the stepped-up basis. If the home appreciated further while you lived in it, the step-up plus the $250,000 exclusion can shelter a large amount of gain. The catch is the two-year residency requirement. Simply inheriting the home and leaving it vacant does not qualify. You have to actually live there.
If You Rented the House Out First
Some heirs rent the property for a while before selling. That creates an extra tax wrinkle. As a landlord you must depreciate the home using your stepped-up basis as the starting point. Any depreciation you claim after the date of death reduces your adjusted basis and is subject to recapture at a 25% rate when you sell, which is higher than the ordinary long-term capital gains rate. Any depreciation your parent took before death is wiped out by the step-up and does not get recaptured.
Renting also ends the home’s status as your personal residence, which affects your eligibility for the Section 121 exclusion described above. If you plan to rent first and sell later, the timing of each phase drives the tax outcome, and it is worth talking to a tax professional before you start.
Two Things That Can Eat the Proceeds
Federal estate tax is not the problem most families think it is. The exemption for 2026 is $15 million per person, and only value above that threshold is taxed.7Internal Revenue Service. What’s New – Estate and Gift Tax The vast majority of estates owe none and do not file Form 706. A handful of states impose their own estate or inheritance taxes with lower thresholds, though children inheriting from a parent typically get the most favorable treatment. If your parent lived in one of those states, check that state’s rules separately.
Medicaid estate recovery is the issue that actually blindsides heirs. If your parent received Medicaid-funded nursing facility or home-based care after age 55, federal law requires the state Medicaid program to seek repayment from the estate for those services.8Medicaid.gov. Estate Recovery The house is usually the estate’s biggest asset, which makes it the target.
There are protections. States cannot pursue recovery while a surviving spouse, a child under 21, or a blind or disabled child of any age is still living.8Medicaid.gov. Estate Recovery States must also offer hardship waivers when recovery would impose an undue burden, such as when the home is the survivors’ sole income-producing asset or is of modest value. If none of those exceptions apply, the state can file a claim against the estate or place a lien on the property, and the recovery amount comes out of the sale proceeds before you receive anything. If you know your parent received long-term Medicaid benefits, find out whether a recovery claim exists before you list the house. Learning about a $200,000 lien after signing a purchase agreement is far worse than learning about it early.
Reporting the Sale
At closing, the settlement agent or title company files Form 1099-S with the IRS reporting the gross proceeds, and sends you a copy.9Internal Revenue Service. Instructions for Form 1099-S
On your annual return, report the sale on Form 8949, Sales and Other Dispositions of Capital Assets. In the date acquired column, enter “INHERITED” instead of a specific date.10Internal Revenue Service. Instructions for Form 8949 Use Part II, the long-term section. Enter the sale price, your stepped-up basis, and any adjustments for selling expenses. The gain or loss then flows to Schedule D of your Form 1040, where it combines with your other capital gains and losses for the year.11Internal Revenue Service. Publication 523 – Selling Your Home
Estimated Tax Payments
A sizeable gain can trigger estimated tax payment requirements. You generally must make estimated payments if you expect to owe at least $1,000 for the year after withholding and refundable credits, and your withholding will not cover at least 90% of your current-year liability or 100% of last year’s (110% if your prior-year AGI exceeded $150,000).12Internal Revenue Service. Large Gains, Lump Sum Distributions, Etc.
If the sale closes partway through the year, you can annualize your income and make a larger estimated payment for the quarter in which you realized the gain, rather than spreading it evenly across all four quarters. Missing an estimated payment when required triggers an underpayment penalty, which is essentially interest on what you should have paid earlier. On a gain of any real size, run the numbers before the next quarterly deadline.
Turning the House Down: Qualified Disclaimers
An heir who does not want an inherited property can formally refuse it through a qualified disclaimer. The property then passes to the next person in line under the will or state intestacy law, as if you never inherited it. The disclaimer must be in writing, delivered within nine months of the date of death, and you cannot have accepted any benefit from the property before disclaiming.13Office of the Law Revision Counsel. 26 USC 2518 – Disclaimers
Why would anyone do this? Sometimes the property carries more liability than value, such as a Medicaid lien that exceeds the home’s worth, or major repair costs the heir cannot handle. Sometimes disclaiming shifts the inheritance to a family member in a lower tax bracket or to a charity. The nine-month window is firm, and once you have moved in, collected rent, or otherwise benefited from the property, the option is gone.
