Capital Gains Tax on an Inherited Home in 2026: The Step-Up That Saves Tens of Thousands

Inheriting a house comes with a tax gift most families do not know they received. Under
IRC Section 1014, the property’s cost basis resets to its fair market value on the date of
death. Every dollar of appreciation that built up during the previous owner’s lifetime — sometimes forty
years of it — disappears for income tax purposes.

A home bought for $150,000 decades ago and worth $400,000 at death carries a $400,000 basis. Sell it at
$410,000 and the taxable gain is $10,000, not $260,000. In many cases an heir who sells promptly owes
nothing at all in federal capital gains tax, saving families tens of thousands of dollars.

The catch is that the benefit is time‑sensitive and it requires documentation. This guide explains how
the step‑up works, how to calculate your taxable gain, the 2026 long‑term capital gains brackets, and
the mistakes that quietly destroy the benefit.

The Step-Up in Basis Under IRC Section 1014

Cost basis is the number the IRS subtracts from your sale price to determine taxable gain. For property
you buy yourself, basis is what you paid plus the cost of improvements. For property you inherit,
Section 1014 replaces that history entirely: your basis becomes the fair market value on the decedent’s date
of death.

This is why inheriting property is not itself a taxable event. No income tax is due at inheritance. You
owe capital gains tax only when you sell, and only on appreciation that occurs after the date of
death. Federal estate tax is a separate matter handled by the estate, and in 2026 it applies only above a
$15,000,000 exemption.

One action item follows immediately from this rule: get a date‑of‑death appraisal from a licensed
appraiser. The IRS can challenge a basis claim that has no third‑party documentation, and a retroactive
appraisal is harder to defend than one ordered at or near the date of death. If you plan to hold the
property for years, order it now anyway.

How to Calculate Your Taxable Gain

The math is more forgiving than most heirs expect, because selling costs and post‑inheritance
improvements are both subtracted before the gain is measured.

In that example the heir owes no federal capital gains tax despite a $20,000 nominal increase over the
date‑of‑death value, because selling costs absorbed it. Ordinary maintenance and repairs do not
increase basis; capital improvements — a new roof, a kitchen renovation, an addition — do. Keep
every receipt from the transition period.

2026 Long-Term Capital Gains Brackets

If you do have a gain, the rate depends on your total taxable income and filing status. Inherited property
is treated as automatically long‑term regardless of how briefly you owned it, so you never pay short‑term
rates. The brackets below reflect IRS Revenue Procedure 2025‑32.

Two surcharges can stack on top. The net investment income tax adds 3.8% once modified adjusted gross
income exceeds $200,000 for a single filer or $250,000 for a married couple. State capital gains tax, where
it exists, applies on top of the federal figure and in a handful of states is taxed as ordinary income.

Why Timing Matters More Than Anything Else

Holding for five years cost that hypothetical heir roughly $28,000 in combined tax that selling promptly
would have avoided entirely. The near‑zero gain window right after the step‑up is the most valuable
tax feature the asset will ever carry, and every year of holding erodes it.

That said, timing should not override common sense. Hold the property if you intend to live in it, if the
rental math clearly wins, or if you can time the sale into a 0%‑bracket year. Calculate the after‑tax
outcome rather than the gross sale price.

Jointly Owned Property and Community Property

Titling changes the size of the step‑up, sometimes dramatically. If the home was held by the decedent
and a surviving spouse as joint tenants with right of survivorship, only the decedent’s half receives a
step‑up; the surviving spouse’s half keeps its original basis. In the nine community property states —
Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington and Wisconsin — both halves
generally receive a full step‑up at the first spouse’s death, and the benefit is far greater.

This is a good reason to review how the home is titled with a CPA before a death occurs, not after.
Retitling can also work against you: property gifted during life keeps the giver’s original basis, so
accepting a “gift” of the house months before a parent dies can forfeit the entire step‑up and convert a
tax‑free sale into a fully taxable one.

The Section 121 Exclusion If You Move In

If your gain is large because the property appreciated substantially after you inherited it, moving in
can unlock another exclusion. Under IRC Section 121, once you have owned and used the home as your principal
residence for at least two of the five years before selling, you can exclude up to $250,000 of gain as a
single filer or $500,000 as a married couple filing jointly.

Stack that on top of the step‑up and the tax‑free room becomes substantial. Inherit a home with a
$500,000 basis, live in it two years while it climbs to $760,000, then sell as a married couple: the $260,000
gain falls entirely inside the $500,000 exclusion and nothing is owed.

Rental Property and Depreciation Recapture

If the decedent had used the property as a rental, the step‑up generally resets the accumulated
depreciation too. Your gain calculation starts from the fair market value at death, and the decedent’s
claimed depreciation does not carry over to you.

What does carry over is your own. If you rent the property after inheriting it, you begin
depreciating from your stepped‑up basis over 27.5 years, and when you eventually sell you owe 25%
unrecaptured Section 1250 tax on the depreciation you claimed. Track it carefully from day one.

Reporting the Sale

1. Confirm title has transferred from the estate to you; the home cannot close while it is still in probate.
2. Order a date‑of‑death appraisal and keep it with the estate file permanently.
3. Collect receipts for every capital improvement made after the date of death.
4. Expect a Form 1099‑S from the title company reporting gross proceeds.
5. Report the sale on Form 8949 and Schedule D even if the taxable gain is zero — the IRS sees the 1099‑S and will issue a notice if no basis is reported.
6. Use the inherited‑property code on Form 8949 so the gain is automatically classified as long‑term.
7. Confirm with the estate representative whether the alternate valuation date under IRC Section 2032 was elected, which changes your basis to the value six months after death.

Common Mistakes That Destroy the Benefit

• Taking title as a gift before death. This forfeits the step‑up and makes the entire lifetime gain taxable.
• Relying on a property tax assessment or an online estimate as basis. Neither is admissible evidence of fair market value.
• Selling and never reporting it. The 1099‑S guarantees the IRS knows the gross proceeds.
• Ignoring selling costs. Commissions, title insurance, escrow fees and transfer taxes all reduce the gain.
• Forgetting the 3.8% net investment income tax. It applies above relatively modest income thresholds and catches many heirs by surprise.
• Assuming state tax follows federal. A few states tax capital gains as ordinary income and offer no preferential rate.
• Failing to check whether the decedent’s state imposes an inheritance tax. That is a separate state‑level tax paid by the heir, not the estate.

Frequently Asked Questions

Do I pay tax when I inherit a house?

No. Inheriting property is not a taxable event for income tax purposes. Under IRC Section 1014, you receive a stepped-up basis equal to the fair market value on the date of death, which erases all appreciation that occurred during the previous owner’s lifetime. You owe capital gains tax only when you sell, and only on appreciation that occurs after you inherit. Federal estate tax, if any, is handled by the estate and in 2026 applies only above a $15,000,000 exemption.

What is the step-up in basis?

The step-up in basis resets the cost basis of inherited property to its fair market value on the date of the original owner’s death. Cost basis is the number the IRS subtracts from the sale price to calculate taxable gain. If a parent bought a home for $100,000 and it was worth $600,000 at death, the heir’s basis is $600,000, not $100,000. Decades of appreciation are permanently excluded from income tax.

How much capital gains tax will I pay if I sell an inherited home in 2026?

It depends on your gain and total income. Long-term capital gains rates in 2026 are 0%, 15% or 20%. A single filer pays 0% up to $49,450 of taxable income, 15% up to $545,500, and 20% above that. Married couples filing jointly pay 0% up to $98,900 and 15% up to $613,700. Most heirs who sell promptly after inheriting owe little or nothing because selling costs absorb the small gain above the stepped-up basis.

Do I need an appraisal for the stepped-up basis?

You should get one. The step-up happens automatically under federal law and requires no action, but a formal date-of-death appraisal from a licensed appraiser is your documentation. The IRS can challenge a basis claim without third-party evidence, and a retroactive appraisal is harder to defend than one ordered at or near the date of death. Order it even if you plan to hold the property for several years.

Can I avoid capital gains tax by moving into the inherited home?

You can use the Section 121 exclusion if the gain is significant. Once you have owned and used the home as your principal residence for at least two of the five years before selling, you can exclude up to $250,000 of gain as a single filer or $500,000 as a married couple filing jointly. Combined with the stepped-up basis, that can eliminate the tax entirely on a modestly appreciated home.

What happens if I inherit a home jointly with my spouse?

If the home was held by the decedent and a surviving spouse as joint tenants with right of survivorship, only the decedent’s half receives a step-up and the surviving spouse’s half keeps its original basis. In community property states, both halves generally get a full step-up at the first spouse’s death, which is considerably more favorable. Review how the home is titled with a CPA before a death occurs, because retitling after the fact is limited.

Do I have to report the sale if I owe no tax?

Yes. The title company will issue Form 1099-S reporting the gross proceeds to the IRS. Even with a zero taxable gain, you must report the sale on Form 8949 and Schedule D and show your basis calculation. Failing to report it triggers an automated IRS notice because the proceeds appear without any offsetting basis.

Get the Basis Right Before You List

The two things that protect this benefit are a date‑of‑death appraisal and a clean record of your
selling costs. Order the appraisal now, keep every receipt, and confirm with a CPA whether the estate
elected the alternate valuation date — it changes the number you start from. If the home is still in
probate, estimate the probate costs before you assume the
proceeds are available, and if you are planning ahead rather than reacting, our estate planning checklist covers the documents that keep a
transfer out of court entirely.
