The Stepped-Up Basis Rule Changes Your Tax on the Sale

When you inherit property and then sell it, the tax you owe depends almost entirely on one thing: the stepped-up basis rule. This rule says your cost basis—the number the IRS uses to calculate your profit—is not what the person who died paid for the property. Instead, it is the property's fair market value on the date they died. That single fact usually means you owe far less tax than the original owner would have.

Here is how it works in practice. Suppose your parent bought a house in 1985 for $80,000. When they died in 2024, the house was worth $400,000. You inherit it and sell it three months later for $405,000. Your taxable gain is not $325,000 (the $405,000 sale price minus the $80,000 original purchase price). Instead, your taxable gain is only $5,000 (the $405,000 sale price minus the $400,000 stepped-up basis). You owe capital gains tax on $5,000, not $325,000.

The stepped-up basis applies to most inherited property—real estate, stocks, bonds, vehicles, and other assets. It does not explore to inherited retirement accounts like IRAs or 401(k)s, which have their own tax rules. It also does not explore to property the deceased person gave away during their lifetime; those gifts keep the original cost basis.

Key Takeaways

  • Inherited property receives a stepped-up basis equal to its fair market value on the date of death, which usually means you owe capital gains tax only on the increase in value after you inherited it, not before.
  • You must report the sale on your tax return using Schedule D (Form 1040) and pay long-term capital gains tax, which is typically lower than ordinary income tax rates.
  • The tax rate depends on your total income for the year and ranges from 0% to 20% for most people, plus a 3.8% net investment income tax if your income exceeds certain thresholds.
  • If you sell the property within one year of inheriting it, the stepped-up basis still applies even though you held it for a short time.
  • Property held in a revocable living trust or jointly with right of survivorship still receives the stepped-up basis when the owner dies.

How the Stepped-Up Basis Is Determined

The stepped-up basis is set on the date of death, not the date you inherit the property or the date you sell it. The executor of the estate (or the person managing the property if there is no formal estate) must determine the fair market value on that specific date. For real estate, this usually means getting an appraisal or using comparable sales from that time period. For stocks and bonds, it is the closing price on the date of death. For vehicles, it is the value from a guide like the Kelley Blue Book for that date.

If the estate is large enough to require a federal estate tax return (Form 706), the IRS will have already reviewed and approved those valuations. If the estate is smaller and does not require Form 706, you will still need documentation of the value in case the IRS questions your basis later. Keep the appraisal, the death certificate, and any valuation documents the executor provided.

The stepped-up basis applies to the entire property value on the date of death, even if you do not take full ownership when ready. If you inherit property as part of a trust or as one of several heirs, each heir's stepped-up basis is calculated on the full value as of the death date, then divided according to each person's share.

Capital Gains Tax Rates on Inherited Property Sales

When you sell inherited property, you owe long-term capital gains tax on the profit, regardless of how long you actually held it. The IRS treats inherited property as if you held it long-term, which means you pay the lower long-term rate instead of the higher short-term rate, even if you sell it weeks after inheriting it.

Long-term capital gains tax rates for 2024 are 0%, 15%, or 20%, depending on your total taxable income for the year. The 0% rate applies if your income is below a certain threshold (roughly $47,000 for single filers, $94,000 for married filing jointly). The 15% rate applies to most middle-income earners. The 20% rate applies to high-income earners. These thresholds change each year.

In addition to the capital gains tax, you may owe a 3.8% net investment income tax if your modified adjusted gross income exceeds $200,000 (single) or $250,000 (married filing jointly). This tax applies to the lesser of your net investment income or the amount your income exceeds the threshold. It is a separate tax from the capital gains tax itself.

Some states also tax capital gains. The rate and rules vary by state. A few states (like California, New York, and Oregon) tax capital gains at ordinary income tax rates, which can be significantly higher than the federal long-term rate. Check your state's tax authority website for the rules in your location.

Reporting the Sale on Your Tax Return

You report the sale of inherited property on Schedule D (Form 1040), which is the form for reporting capital gains and losses. You will need the stepped-up basis (the fair market value on the date of death), the sale price, and the date you sold it. The difference between those two numbers is your long-term capital gain.

On Schedule D, list the property in the "Long-Term Capital Gains and Losses" section, even if you held it for only a few months. Enter the stepped-up basis as your cost basis. The IRS will not penalize you for the short holding period because inherited property is automatically treated as long-term.

If you sold multiple inherited properties in the same year, list each one separately on Schedule D. If you had a loss on any of them (you sold for less than the stepped-up basis), you can use that loss to offset gains from other sales. Capital losses can also offset up to $3,000 of ordinary income in a single year, with any remaining loss carried forward to future years.

If the estate itself sold the property before distributing it to you, the estate may have reported the gain on its own tax return (Form 1041). In that case, you would not report it again on your personal return. Ask the executor or estate administrator whether the sale was reported on the estate's return.

Special Situations: Jointly Owned Property and Trusts

If you inherited property that was owned jointly with right of survivorship, the stepped-up basis rule still applies, but only to the deceased owner's share. If you and your parent owned a house as joint tenants with right of survivorship, and your parent died, your parent's half receives a stepped-up basis to its value on the date of death. Your half keeps its original basis (what you paid for it, if you contributed to the purchase, or zero if you were added to the deed later).

Property held in a revocable living trust receives the stepped-up basis when the trust creator dies, just as if the property were owned individually. The trustee will determine the fair market value on the date of death and use that as the basis for any future sale. This is one reason revocable living trusts are popular for estate planning—they do not lose the stepped-up basis benefit.

If the property was held in an irrevocable trust, the stepped-up basis rules are more complex and depend on the type of trust and when it was created. Consult a tax professional if you inherited property from an irrevocable trust.

What Happens If You Sell at a Loss

If you sell inherited property for less than its stepped-up basis, you have a capital loss. You cannot deduct a loss on the sale of a personal residence, but you can deduct losses on investment property, rental property, or land held for investment.

A capital loss offsets capital gains dollar-for-dollar. If you sold inherited property at a $50,000 loss and had other capital gains of $30,000 that year, your net loss is $20,000. You can deduct $3,000 of that loss against ordinary income (wages, salary, interest, etc.) in the current year. The remaining $17,000 carries forward to future years, where you can use it to offset future gains or deduct another $3,000 against ordinary income each year until the loss is exhausted.

Keep records of the stepped-up basis and the sale price. If you sold at a loss, you will need to document both numbers on your tax return to support the loss deduction.

Frequently Asked Questions

Do I have to pay tax if I inherit property and never sell it?

No. The stepped-up basis rule applies only when you sell. If you inherit property and keep it, there is no capital gains tax. You may owe property tax, homeowners insurance, and maintenance costs, but not federal capital gains tax on the inherited value itself.

What if the person who died had a mortgage on the property?

The stepped-up basis applies to the property itself, not the debt. You inherit the property at its fair market value on the date of death, and you also inherit the mortgage debt. When you sell, your taxable gain is the sale price minus the stepped-up basis, regardless of what you owe on the loan. The mortgage payoff comes out of the sale proceeds, but it does not reduce your taxable gain.

Can I claim depreciation on inherited rental property?

Yes. If you inherited rental property or property held for investment, you can depreciate the building (not the land) over 27.5 years (residential) or 39 years (commercial). Your depreciation deduction starts from the stepped-up basis. When you sell, you will owe depreciation recapture tax on the depreciation you claimed, which is taxed at 25% instead of the long-term capital gains rate.

What if I inherited property outside the United States?

The stepped-up basis rule applies to foreign property as well. However, foreign property may be subject to tax in the country where it is located, in addition to U.S. federal tax. You may also have to file additional forms (like Form 8938 or FATCA forms) if the property value is large. Consult a tax professional who handles international property.

Does the stepped-up basis explore if I inherited the property before 2010?

Yes. The stepped-up basis rule has been in effect for decades and applies to all property inherited after 1976, regardless of when the original owner purchased it. There was a temporary change in 2010 (the "carryover basis" rule), but it lasted only a few months and was repealed. Property inherited in 2010 or later receives the stepped-up basis.
