Capital Gains Tax on Inherited Property: How the Stepped-Up Basis Works
Inheriting a house doesn't automatically create a tax bill. The IRS resets your cost basis to the property's fair market value on the date the original owner died. This is called the stepped-up basis. Because of that reset, you generally owe capital gains tax only on the growth that occurs after you inherit, not on decades of appreciation the original owner never paid tax on.
This guide explains how the stepped-up basis works, what happens when there are multiple heirs, and the exact math in a worked example before you sell.
You Don't Owe Tax Just for Inheriting Property
Inheriting real estate is not a taxable event on its own. The IRS does not tax you simply for receiving a house, land, or other property from someone's estate. Tax only enters the picture if and when you sell the property for more than your basis.
This surprises a lot of heirs. Many assume they owe tax on the property's full value the moment it passes to them, the way an inheritance of cash might feel like income. Your tax bill actually depends entirely on your basis and your eventual sale price, not on the property's value at the moment you inherit it.
A separate tax, the federal estate tax, can apply to very large estates before assets even reach heirs. The 2026 federal exemption is $15,000,000 per individual, so it affects almost no families. Five states also charge a separate inheritance tax on beneficiaries directly: Kentucky, Maryland, Nebraska, New Jersey, and Pennsylvania.

How the Stepped-Up Basis Actually Works
The stepped-up basis resets your cost basis to the property's fair market value on the date the person who left it to you died. Under IRC Section 1014, that new figure becomes your basis, replacing whatever the original owner paid decades earlier. Basis is the number the IRS subtracts from your sale price to calculate your taxable gain.
Say a parent bought a house in 1985 for $60,000. By the time they pass away, the house is worth $410,000. Without the step-up, an heir who later sold for $410,000 would owe tax on $350,000 of gain, the entire lifetime of appreciation. With the step-up, the heir's basis becomes $410,000 instead, so selling at that same price produces zero taxable gain.
The step-up also resets your holding period in one specific way: the IRS automatically treats inherited property as long-term, no matter how long you personally hold it before selling. Sell it the day after you inherit, and you still qualify for long-term capital gains rates, not the higher short-term rates that apply to most other quick sales. That detail alone can save thousands of dollars for heirs who need to sell fast.
A Worked Example: Selling Inherited Property Eight Months Later
Here is a full example with a hypothetical family, not a real sale. A mother bought her home in 1990 for $95,000. She dies in early 2026, and a certified appraisal values the house at $415,000 on her date of death. That $415,000 becomes her son's stepped-up basis.
Eight months later, after some minor repairs and a real estate agent's 6% commission, her son sells the house for $430,000. Selling costs run about $25,800, so his amount realized is $404,200. Subtract his $415,000 basis, and he actually shows a small loss of $10,800, not a gain, because the home's value dipped slightly between the appraisal and the sale.
Compare that to what would happen without the step-up. Taxing the full $335,200 gain between the original $95,000 basis and the $430,200 sale price, at a 15% federal long-term rate, would cost roughly $50,000 in tax. The stepped-up basis makes the entire difference. Run your own numbers, including your specific basis and sale price, through ModernWallet's capital gains tax calculator.
Multiple Heirs and Jointly Inherited Property
Each heir who co-inherits a property gets their own proportional share of the stepped-up basis. If three siblings inherit a house equally, each one's basis is one-third of the fair market value on the date of death, not one-third of what the parent originally paid.
This matters most when siblings disagree about what to do with the house. One heir who wants to keep the property often buys out the others at their share of the current value, and that buyout price, not the original purchase price decades ago, sets the basis for whichever heirs choose to sell their share.
Selling the whole property together, rather than one heir buying out the rest, is usually the simplest path administratively. Each heir then reports their own share of the sale price and their own share of the stepped-up basis on their individual tax return. A written appraisal at the date of death protects every heir equally, since it documents the basis figure the IRS expects everyone to use.
Get a Real Appraisal Before You Decide Anything
A qualified appraisal dated at or near the death is the single most useful document an heir can get. It establishes the fair market value the IRS uses for your basis, and it protects you if the IRS ever questions the number on an audit.
Waiting too long to get that appraisal creates real risk. Home values move, and a value estimated months or years after death is much harder to defend than one dated close to the event. If probate delays the appraisal, ask the executor to order one as early in the process as possible.
Keep every receipt for capital improvements you make after inheriting, like a new roof or a kitchen remodel. Those costs add to your basis and lower your eventual taxable gain, the same as they would for any other property owner. Routine repairs and maintenance do not count.

How Inherited Property Differs From Land You Bought Yourself
Inherited property already carries a reset basis, so most of the strategies that shelter gains on a purchased parcel do not apply the same way. A landowner who bought land decades ago and wants to avoid tax on decades of appreciation has real reasons to consider a 1031 exchange or an installment sale, covered in our guide on avoiding capital gains tax on a land sale. An heir selling shortly after inheriting usually has little or no gain left to defer in the first place.
Age also does not change the tax rate on an inherited sale, the same way it does not change the rate on any other capital gain. If you are retired and inherited property, see our guide on capital gains tax for seniors for how your other income and withdrawal timing can still shape your total tax bill.
The biggest risk for most heirs is not the stepped-up basis itself. It is holding the property too long after inheriting without tracking value, letting the market move the price away from your documented basis before you have decided whether to sell.
Frequently asked questions
Do I have to pay tax the moment I inherit a house?
No. Inheriting real estate is not a taxable event by itself. You only owe capital gains tax if you later sell the property for more than your stepped-up basis, which is the fair market value on the date the previous owner died.
What is the stepped-up basis?
The stepped-up basis is the property's fair market value on the date the person who left it to you died. Under IRC Section 1014, that value replaces the original owner's purchase price as your cost basis, so you're only taxed on appreciation after that date.
Is inherited property always taxed as a long-term gain?
Yes. The IRS treats any inherited property as long-term, no matter how long you personally hold it before selling. That means you qualify for the lower long-term capital gains rates even if you sell within days of inheriting.
How do I find my basis if the house wasn't appraised right when the owner died?
Order a retroactive, or 'date of death,' appraisal as soon as possible. An appraiser can estimate the historical fair market value using comparable sales from around that date. The longer you wait, the harder that estimate becomes to support.
Does selling inherited property affect my Social Security or Medicare premiums?
It can. A large gain adds to your taxable income for the year, which can push more of your Social Security benefit into taxable territory and can raise Medicare Part B premiums two years later. See our guide on whether Social Security is taxable for the thresholds.
What if three siblings inherit one house together?
Each sibling gets their own equal share of the stepped-up basis, based on their ownership percentage. If the house sells, each heir reports their own share of the sale price and their own share of the basis on their individual tax return.
