You Inherited a House and Sold It. Are You Going to Owe Capital Gains Tax?

You inherit a house. A few months later, you sell it. Then you start wondering: am I going to owe a massive tax bill on this?

It's one of the first questions families ask me, and it makes sense. Most people have heard about capital gains tax on real estate. But the rules for inherited property are different — and in many cases, more generous than you'd expect.

Here's what you need to know. This is not tax advice. I'm a real estate agent, not a CPA. But I can walk you through the basics so you know what questions to ask when you talk to a tax professional.

What Is Capital Gains Tax on Real Estate?

Capital gains tax is what you may owe when you sell an asset for more than your basis in it. The difference between your adjusted basis and what you sell it for is generally your gain, and the IRS taxes that gain.

For most real estate, it works like this: you buy a house for $200,000, sell it years later for $300,000, and you may owe tax on that $100,000 difference. There are exemptions if it was your primary residence, but that's a different conversation.

With inherited property, though, the math changes. You didn't buy the house. Someone left it to you. So what counts as your "purchase price"?

That's where stepped-up basis comes in — and it's the single most important thing to understand about capital gains on inherited property.

Stepped-Up Basis: The Rule That Changes Everything

When you inherit real estate, the IRS generally doesn't use the price the original owner paid decades ago. Instead, your "basis" — the number the IRS uses as your starting point — is usually stepped up to the fair market value on the date the person passed away. In some cases, an estate may use an alternate valuation date if that election applies, but the general rule is date-of-death value.

Here's what that means in practice.

Let's say your mom bought her house in 1985 for $80,000. When she passed away in 2024, the house was worth $350,000. You inherit it.

Your basis usually isn't $80,000. It's $350,000 — the value on the date she died.

If you sell the house six months later for $355,000, your taxable gain usually isn't $275,000. It's closer to $5,000, before adjustments for selling costs and anything else that changes basis.

That's a massive difference.

The stepped-up basis rule exists so heirs usually aren't hit with huge tax bills on appreciation that happened during someone else's lifetime.

How the Date of Death Valuation Works

The fair market value on the date of death usually becomes your basis. But how do you determine that value?

Most families use one of these methods:

• Professional appraisal. The estate hires a licensed appraiser to value the property as of the date of death. This creates a formal record.
• Comparative market analysis (CMA). A real estate agent pulls recent sales of similar homes to estimate value. Not as formal as an appraisal, but it can still be useful as supporting documentation.
• Estate tax reporting. If a federal estate tax return is required, the value reported there can matter because basis consistency rules may apply.

If the estate goes through probate, the court or the professionals handling the estate may require a formal appraisal. If not, you'll still want documentation that shows how you arrived at the date-of-death value — especially if you're claiming a high basis to minimize capital gains.

Your CPA or estate attorney can tell you what level of documentation makes sense for your situation.

Selling Soon After Inheriting: What to Expect

Many families sell inherited property within the first year. The house might be too far away to manage. It might need costly repairs. Siblings might need to split the proceeds and move on.

When you sell quickly, your taxable gain is usually small — sometimes zero — because your basis was generally reset close to current market value.

If the house was worth $400,000 when you inherited it and you sell it nine months later for $405,000, your gain is usually about $5,000 before selling costs. If you sell it for $398,000 because the market softened or you priced it to move quickly, you may have little or no taxable gain.

Selling soon after inheriting often means minimal or no capital gains tax. The stepped-up basis does most of the work.

What If You Wait Years to Sell?

Let's say you inherit the house, and instead of selling right away, you decide to rent it out. Or you move into it for a few years. Or you just hold onto it while you figure things out.

Now your stepped-up basis is still generally the same — the value on the date of death, unless an alternate valuation date applied. But the sale price might be much higher if the market has appreciated.

If the house was worth $300,000 when you inherited it and you sell it five years later for $400,000, your taxable gain may be $100,000, subject to adjustments for improvements, depreciation, and selling costs.

Inherited property generally gets long-term capital gains treatment, even if you didn't hold it for more than a year. That part surprises people, but it is a real rule.

The longer you wait, the more potential for appreciation — and the larger your potential tax bill.

There's no right or wrong timeline. Some families need to sell immediately. Others want to keep the property. Just know that waiting can increase your taxable gain if the market goes up.

Improvements, Repairs, and Selling Costs

You can add certain costs to your basis, which reduces your taxable gain.

Selling costs like agent commissions, title fees, and closing costs generally reduce your gain. If you inherited a house with a basis of $300,000, sold it for $320,000, and paid $18,000 in commissions and fees, your taxable gain may be closer to $2,000, not $20,000.

Capital improvements — things like a new roof, HVAC system, or kitchen remodel — can generally be added to your basis if you made them after inheriting. Repairs and maintenance (fixing a leaky faucet, repainting) usually don't count by themselves.

Depreciation can also come into play if you converted the home to a rental, which is where a CPA earns their coffee.

Your CPA will walk you through what you can and can't deduct. Keep receipts for everything.

State Taxes and Other Considerations

Most states follow the general federal approach on basis, but some have their own capital gains taxes, inheritance taxes, or filing rules that can affect what you owe.

A few states also have unique rules about property transfers, estate taxes, or how inherited property is treated for tax purposes.

If the property is in a different state than where you live, you may need to file a tax return in that state when you sell.

This is one of those areas where a CPA who understands both your state and the property's state is worth every penny.

When You Should Talk to a CPA

As soon as you know you're inheriting property, talk to a tax professional. Before you sell. Before you make improvements. Before you decide whether to rent it or move in.

Here's what a good CPA can help you figure out:

• What your stepped-up basis actually is and what documentation you need
• Whether selling now or later makes sense from a tax perspective
• How to handle any depreciation if you rented the property
• What happens if you inherited the property with siblings
• State-specific rules that might affect your tax bill
• Whether you qualify for any exclusions, elections, or other tax treatment options

Every family's situation is different. A general blog post can't replace actual tax advice. But knowing the basics helps you ask the right questions.

What Families Often Ask

Do I owe capital gains tax if I inherit a house and sell it right away?

Usually no, or very little. Your basis is generally the fair market value on the date of death, so if you sell soon after for roughly the same amount, there's little or no taxable gain. You may still owe tax on appreciation that happened between the inheritance date and the sale date.

What if the house went down in value since I inherited it?

If you sell for less than the stepped-up basis, you may have a capital loss. Whether that loss is deductible depends on how the property was held and used. Losses on personal-use property generally aren't deductible. If the property was rented or used for business, different rules may apply — talk to your CPA.

Do all heirs get the stepped-up basis, or just one person?

Each heir generally gets basis in their own share of the property. If you and your sister inherit a house worth $400,000, you each generally have a basis of $200,000 in your half. When you sell, each of you calculates gain or loss on your own share.

Does the stepped-up basis apply if the property was in a trust?

Usually yes for some trusts, especially revocable living trusts, but not always. Irrevocable trusts can be more complicated. Your estate attorney and CPA will need to look at how that specific trust was structured.

A Final Word: This Is General Information, Not Tax Advice

Everything in this post is general information about how capital gains and stepped-up basis often work for inherited property. It is not tax advice, legal advice, or financial advice.

Tax rules change. Every family's situation is different. State laws vary. What works for one inherited property may not work for another.

Before you make any decisions about selling, renting, or transferring inherited property, talk to a licensed CPA or tax attorney who can review your specific situation.
