I Inherited a House — Do I Owe Taxes If I Sell?

TL;DR: Most of the value you inherited isn't taxable at all — thanks to the stepped-up basis. Selling soon after inheriting often means little to no gain.

_Last reviewed: July 2026 · 4 min read_

If you inherited a house and are worried about a giant tax bill on the sale, the honest answer is: most of the value passes through untaxed. There's generally no federal income tax simply for inheriting a house. When you sell, you're taxed only on gain above the stepped-up basis — the fair market value at the date of death, not the price your parent paid decades ago.

Okoniq Property Hub stores the appraisal, closing documents, and post-inheritance improvements so the tax picture at sale is clean. Here's what actually gets taxed.

Is there federal tax just for inheriting?

No. Federal law doesn't tax inheritances at the recipient level. Some large estates pay federal estate tax before distribution — but that's paid by the estate, not the heir, and the exemption is currently over $13 million per person (2026), so it rarely applies to ordinary families.

The heir receives the property with no immediate tax event.

What's the stepped-up basis?

When someone dies, the assets they held (including real estate) get a new basis equal to fair market value at the date of death. This is one of the most valuable provisions in the tax code for ordinary families — see our worked example.

Practical result: a house your parent bought for $60,000 in 1985 that's worth $500,000 when they die has a new basis of $500,000 in your hands. If you sell for $510,000, your taxable gain is $10,000 — not $450,000.

What if the sale price is close to fair market value?

Often the case if you sell within a year or two of inheriting. Your gain is:

Sale price — Selling costs — Stepped-up basis = Gain

Because you had zero contribution to the property's appreciation (it happened before you owned it), the gain from date-of-death to sale is often small. Selling costs (agent commission ~5-6%, closing fees, staging) frequently wipe out even that small gain.

Many inherited homes sold within 12-18 months of death produce near-zero or actual losses — the losses are non-deductible for a residence but may be deductible if the property was held as investment or rental.

What if I hold the property for years before selling?

Then you have two potential gain components:

1. Post-inheritance appreciation — market value growth after the date of death
2. Depreciation recapture if you rented it out (see Section 179 vs bonus depreciation for rentals for how depreciation works)

Post-inheritance gain is treated as long-term capital gain if held over a year (which inherited property always is — the IRS treats it as automatically long-term regardless of your actual holding period).

What about state taxes?

Federal is only part of the picture. A handful of states have their own inheritance tax on heirs:

• Iowa (phasing out by 2025)
• Kentucky
• Maryland
• Nebraska
• New Jersey
• Pennsylvania

Rates and exemptions vary by relationship to the deceased (surviving spouse and children generally pay less). Additionally, most states with state income tax will tax capital gains on the sale.

Check your state, or ask the estate's attorney — this is exactly what they're paid for.

Keep inherited-property paperwork together

The paperwork that establishes stepped-up basis and defensible selling costs is easy to lose in the year after a death. Okoniq Property Hub stores the appraisal, deed transfer, executor documents, and every receipt so a future sale is a lookup, not archaeology. Related: how to calculate cost basis on an inherited house, stepped-up basis explained with a real example, and the Taxes & Accounting hub. The IRS's Publication 559 (Survivors, Executors, and Administrators) is the canonical federal reference.

Frequently asked questions

Do I have to report the sale even if there's no gain?

If you receive a Form 1099-S from the closing agent, yes — you'll report the sale and calculate the gain (which may be zero or a loss). If no 1099-S is issued, you generally don't need to report a wash sale, but check with your CPA.

What if multiple siblings inherit the house together?

Each sibling gets a stepped-up basis in their share. When one sibling buys out the others, or you all sell together, the gain is calculated per-share.

What about the primary-residence exclusion?

If you (the heir) actually move into the inherited house and live in it for 2 of the next 5 years, you can qualify for the Section 121 $250K/$500K exclusion on top of the stepped-up basis. This is one of the tax code's best legal wins for heirs who move in.

FAQ

How much of an inherited house's value is taxed when I sell it?

Only the increase in value after the date of death is taxed. If your parent's house was worth $500,000 when they died and you sell for $510,000, you're taxed on $10,000 of gain — not the full appreciation that occurred during their lifetime.

Can I deduct a loss if I sell an inherited house for less than it was worth at death?

Only if you converted the property to rental or investment use before selling. If you sell it as-is without renting it out, the loss is considered personal and non-deductible, just like selling your own home at a loss.

Do I need an official appraisal to prove the stepped-up basis?

The IRS doesn't require a formal appraisal, but you need credible evidence of fair market value at the date of death — a professional appraisal, recent comparable sales, or the county tax assessment are common methods. Without documentation, the IRS may challenge your basis in an audit.

What happens if I inherit a house that still has a mortgage on it?

The mortgage doesn't change your stepped-up basis — your basis is still the full fair market value at death. You're responsible for the mortgage payments (or the estate pays it off before transfer), but the debt itself isn't subtracted from your tax basis.
