Do You Owe Capital Gains Tax When You Sell an Inherited House?
3 min read · Last updated 2026-08-03 · Reviewed by Camilo Palacio, Licensed Florida Real Estate Professional (License #3280644, REALTOR®)
Most people who sell an inherited house owe little or no federal capital gains tax. The IRS resets the home's tax basis to its fair market value on the date the original owner died, a rule called step-up in basis. Tax applies only to gain above that reset value, not the original purchase price. Cash Flow Deals is one option heirs can use to lock a net price before repairs are scoped.
| Factor | Traditional Route | Cash Flow Deals |
|---|---|---|
| Repairs before selling | Heir often pays for repairs and updates before listing | Net price locked before repairs are scoped |
| Timeline to close | Weeks to months of showings and negotiations | Faster path through a licensed local broker partner's network |
| Who pays the fee | Commission negotiated separately, per the 2024 NAR Sitzer/Burnett settlement (effective August 17, 2024) | Paid as a separate line item on the closing statement, not a markup on price |
How Step-Up in Basis Resets the Tax Math
The IRS does not tax an inherited house based on what the original owner paid for it decades ago. Under federal tax law, the home's basis resets to its fair market value on the date the original owner died. This is called step-up in basis, and it applies automatically, without any paperwork filed at the time of death. If a parent bought a house for $40,000 in 1985 and it was worth $380,000 the day they died, $380,000 becomes the new basis for the heir who inherits it. Selling at $380,000 produces no taxable gain at all.
What Counts as Taxable Gain on an Inherited House
Taxable gain is the sale price minus the stepped-up basis minus qualifying selling costs like commissions, transfer taxes, and closing fees. If the stepped-up basis is $380,000 and the house sells for $400,000 after $20,000 in selling costs, taxable gain is zero. If it sells for $430,000 after the same costs, taxable gain is $30,000, and federal long-term capital gains rates of 0%, 15%, or 20% apply depending on the seller's income. Most heirs sell close to the stepped-up value, since that value was typically set by a recent appraisal or the local market at the time of death, which is why most inherited-house sales generate little or no federal tax.
Inherited Property Gets Long-Term Treatment Automatically
Federal tax law treats property acquired through inheritance as held long-term, even if the heir sells it the same week they receive it. This matters because long-term capital gains rates of 0%, 15%, or 20% are almost always lower than short-term rates, which are taxed as ordinary income. An heir does not need to hold the house for a year to get the long-term rate. This rule exists specifically for inherited property and does not apply to property an heir buys on their own.
State Estate and Inheritance Taxes Are a Separate Question
Federal capital gains tax is only one piece of the picture. A small number of states charge their own estate tax or inheritance tax, separate from the federal step-up in basis rule described here, and the rules on who owes what vary significantly by state. Anyone selling an inherited house should confirm the specific state and county requirements with a licensed local attorney or CPA before assuming the federal rule is the whole story.
Selling an Inherited House Fast: Cash Flow Deals as One Option
Heirs who inherit a house often want to sell quickly, especially if the property sits empty, needs repairs, or is being split among multiple siblings. Cash Flow Deals is a real estate investment company that locks a net price for the house before repairs are scoped, using a novation-based, flat-fee process arranged through a licensed local broker partner. It is not a traditional listing, and it is not a brokerage itself. For an heir who wants a firm number without managing contractor bids or open houses, that locked price can simplify a sale that already has enough moving parts between the estate, the tax return, and other heirs.
Reporting the Sale on a Federal Tax Return
A sale of an inherited house is reported on Schedule D and Form 8949 with the individual federal income tax return for the year of the sale, using the stepped-up basis as the cost basis. Some inherited property sales also require Form 1099-S from the closing agent. A CPA or tax preparer can confirm exactly which forms apply to a specific estate and sale.
Common questions
Do I owe capital gains tax on the full sale price of an inherited house?
No. Tax applies only to the amount the sale price exceeds the stepped-up basis, which is the home's fair market value on the date the original owner died, not the amount anyone originally paid for it.
Is inherited property always taxed as long-term capital gains?
Yes. Federal tax law treats inherited property as long-term regardless of how long the heir actually owns it before selling, which usually means a lower tax rate than short-term gains.
What if I sell the inherited house for less than its stepped-up value?
Selling below the stepped-up basis produces a capital loss rather than a gain. Personal-use property losses generally are not deductible, so an heir should confirm the specific treatment with a CPA before assuming a refund is coming.
Does Cash Flow Deals change how my capital gains are calculated?
No. The stepped-up basis and the sale price determine the tax math regardless of who buys the house or how the sale is arranged. Cash Flow Deals affects the net price and process, not the federal tax formula.
Do state estate taxes work the same way as the federal step-up in basis rule?
No. A handful of states apply their own estate or inheritance tax with separate rules and thresholds. Confirm the specific requirements in the property's state with a licensed local attorney.
