How Inherited Property Is Taxed: Basis, Estate Tax, and Beyond

The Tax Rule That Erases Decades of Capital Gains at Death

A parent buys a home in 1985 for $80,000. By the time they die in 2024, the home is worth $450,000. Under normal capital gains rules, a sale would generate $370,000 in taxable gain. The heir who inherits and immediately sells the property owes nothing on that $370,000. The stepped-up basis rule—one of the most valuable provisions in the U.S. tax code—resets the property's cost basis to its fair market value at the date of death, erasing the entire built-up gain. Understanding this rule, and the broader tax landscape around inherited assets, can mean six figures in tax savings.

The Step-Up in Basis Explained

Basis is the IRS's term for what you paid for an asset, adjusted for improvements and other factors. When you sell an asset, your taxable gain equals sale price minus basis. A higher basis means less taxable gain.

When property is inherited, the heir's basis is stepped up—or in some cases stepped down—to the asset's fair market value on the decedent's date of death. This applies to virtually all capital assets: real estate, stocks, bonds, business interests, collectibles, and more.

• Step-up scenario: Parent's stock purchased for $20,000 is worth $200,000 at death. Heir inherits with a $200,000 basis. Heir sells immediately for $200,000: zero taxable gain.
• Step-down scenario: Parent's asset purchased for $500,000 is worth $300,000 at death. Heir inherits with a $300,000 basis. If the heir had inherited the original $500,000 basis, they'd have a $200,000 loss to offset gains—but the step-down eliminates that loss as well.
• Alternate valuation date: Estates can elect to use asset values six months after the date of death if doing so reduces the estate's taxable value. Any sale within that six-month period is valued at the date of sale.

Community Property States and the Double Step-Up

In the nine community property states—Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington, and Wisconsin—both spouses' halves of community property receive a step-up at the death of the first spouse to die. This double step-up is a substantial advantage over common-law states, where only the deceased spouse's half gets the step-up.

A couple in California who bought a home together for $200,000, now worth $1,000,000, would have their entire basis stepped up to $1,000,000 when one spouse dies. The surviving spouse could sell the home with no capital gains liability on the appreciation—in addition to the $500,000 primary residence exclusion under Section 121 if they continue to live in the home.

Federal Estate Tax: Who Actually Pays

The federal estate tax applies to estates above a threshold—the exemption amount—which is adjusted for inflation annually. For 2024, the federal estate tax exemption is $13.61 million per individual ($27.22 million for married couples using portability). Only estates exceeding these thresholds owe federal estate tax. The top marginal rate is 40%.

The elevated exemption was established by the Tax Cuts and Jobs Act (TCJA) of 2017 and is scheduled to sunset after December 31, 2025, reverting to roughly half the current amount (inflation-adjusted from the pre-TCJA $5 million base). Congress may act to extend the provisions, but absent legislation, estates that are currently below the threshold could become taxable after 2025.

State Inheritance and Estate Taxes

Twelve states and the District of Columbia levy their own estate taxes, often with much lower exemptions than the federal threshold. Six states impose inheritance taxes on beneficiaries based on their relationship to the decedent.

Inheritance tax rates and exemptions depend heavily on the heir's relationship to the decedent. Surviving spouses are typically exempt. Children may receive favorable rates or full exemptions. More distant relatives and unrelated heirs face the highest rates—up to 15% in Pennsylvania for distant heirs.

Selling an Inherited Home: The Special Rules

The stepped-up basis makes immediate sales nearly tax-free. But heirs who hold inherited property must understand several additional rules.

• Automatic long-term status: Inherited property always qualifies for long-term capital gains treatment regardless of how long the heir holds it. Sell the day after inheriting and you pay long-term rates (0%, 15%, or 20% depending on income)—never the higher short-term rate.
• Section 121 primary residence exclusion: If the heir moves into the inherited home and lives there for at least two of the five years before selling, they can exclude up to $250,000 ($500,000 for married couples) of gain beyond the stepped-up basis.
• Rental income: Heirs who rent inherited property before selling must report rental income as ordinary income and may claim depreciation deductions based on the stepped-up basis value at the date of death.

Strategies to Minimize Taxes on Inherited Assets

Estate planning attorneys use several approaches to maximize after-tax inheritance value. Gifting assets during life using the annual exclusion ($18,000 per recipient in 2024) reduces estate size. Irrevocable trusts can remove assets from taxable estates. Qualified Opportunity Zone investments offer capital gains deferral. Charitable remainder trusts convert appreciated assets into income streams while generating charitable deductions.

The interaction of federal estate tax, state estate tax, state inheritance tax, and capital gains rules creates significant complexity. A Massachusetts resident inheriting a Massachusetts estate worth $3 million would face state estate tax—even though it clears the federal threshold—while a beneficiary in Florida owes nothing at either level, since Florida has neither an estate nor an inheritance tax.
