Capital Gains Tax When Selling Your Home: The $250,000/$500,000 Exclusion Explained

When you sell a home for more than you paid for it, that profit is technically a capital gain — but most homeowners never pay a cent of tax on it, thanks to a specific exclusion built for primary residences. Understanding exactly how it works matters most for anyone whose home has appreciated significantly or who's selling a property that isn't their main home.

The $250,000 / $500,000 Rule

If you've owned and lived in the home as your primary residence for at least 2 of the 5 years before the sale, you can exclude up to $250,000 of profit from capital gains tax if you're single, or up to $500,000 if you're married filing jointly. Profit here means sale price minus your cost basis (what you paid, plus qualifying improvements) — not the full sale price.

The 2-Out-of-5-Years Test

The 24 months of ownership and use don't need to be continuous or the most recent 2 years — they just need to add up to 24 months within the 5 years before the sale date. This matters for people who moved out and rented the home for a period before selling: as long as they lived there at least 2 of the last 5 years, they can still qualify.

You Generally Can't Use It Every Year

The exclusion is limited to one sale every 2 years. If you sold a home and used the exclusion recently, you typically need to wait until the 2-year mark before you can use it again on a different home — one exception being certain partial exclusions for a sale forced by a job change, health issue, or other unforeseen circumstance.

What Happens Above the Exclusion

Any profit above the $250,000/$500,000 threshold is taxed as a regular capital gain — long-term rates if you owned the home more than a year, which is nearly always the case for a primary residence. This mainly matters in high-appreciation markets or for long-term owners: a couple who bought a home decades ago for $150,000 and sells for $900,000 has a $750,000 gain, $250,000 of which is still taxable even after the full $500,000 exclusion.

It Doesn't Apply to Investment Properties

This exclusion is specifically for a primary residence — a rental property, vacation home, or house flip doesn't qualify unless it was genuinely your primary residence for 2 of the last 5 years. Investment property sales are subject to full capital gains tax (and often depreciation recapture on top of it), which is why many real estate investors use a 1031 exchange instead to defer that tax.
