What Is the Primary Residence Capital Gains Exclusion?

The primary residence capital gains exclusion — established under IRS Section 121 — is one of the most valuable tax benefits available to homeowners. It allows qualifying sellers to exclude up to $250,000 of capital gain from federal income tax ($500,000 for married couples filing jointly) when selling their primary residence.

The Basic Rule

Under IRS Section 121, a taxpayer can exclude up to:

• $250,000 of capital gain if filing as single
• $500,000 of capital gain if married filing jointly

from federal income tax when selling their primary residence.

Requirements

To qualify for the full exclusion, you must meet both the ownership test and the use test:

Ownership test: You must have owned the property for at least 2 of the 5 years immediately before the sale.

Use test: You must have used the property as your primary residence for at least 2 of the 5 years immediately before the sale.

The 2 years of ownership and 2 years of use do not need to be the same 2 years, and they do not need to be consecutive — they just need to total at least 24 months within the 5-year window before the sale.

Frequency limit: You cannot use the exclusion more than once in any 2-year period.

How the Exclusion Works in Practice

Example 1 — Full exclusion: You purchased a PCB condo in 2020 for $350,000 and used it as your primary residence. You sell it in 2026 for $700,000. Your capital gain is approximately $350,000 (after selling costs). As a married couple filing jointly, you can exclude $350,000 of gain — the full amount — and owe no federal capital gains tax.

Example 2 — Partial exclusion: You purchased a 30A beach house in 2022 for $600,000 and used it as your primary residence. You sell it in 2026 for $900,000. Your capital gain is approximately $300,000. As a single filer, you can exclude $250,000 — leaving $50,000 subject to capital gains tax.

Example 3 — No exclusion: You purchased a Destin condo in 2020 as a vacation rental and have never used it as your primary residence. You sell it in 2026 for a $400,000 gain. The full $400,000 is subject to capital gains tax.

Partial Exclusion for Unforeseen Circumstances

If you do not meet the full 2-year ownership and use requirements, you may still qualify for a partial exclusion if the sale was due to a change in employment location, health reasons, or unforeseen circumstances (as defined by the IRS).

---

Depreciation Recapture Is Not Excluded

Even if you qualify for the Section 121 exclusion, any depreciation you claimed on the property is subject to depreciation recapture tax at a maximum rate of 25%. The exclusion does not shelter depreciation recapture.

FAQ

How long do I have to live in a home to avoid capital gains tax in Florida?

You must use the property as your primary residence for at least 2 of the 5 years before the sale to qualify for the Section 121 exclusion. Florida has no state capital gains tax, so the only tax at issue is federal.

Can I use the exclusion on a vacation home?

Only if you have used the vacation home as your primary residence for at least 2 of the 5 years before the sale.

Can I use the exclusion more than once?

Yes, but not more than once every 2 years.

Does the exclusion apply to the full sale price or just the gain?

The exclusion applies to the capital gain — the difference between the sale price and your adjusted basis.
