A second home you use personally and never made your main residence usually doesn't qualify for the home-sale exclusion — so the full gain is taxable. The $250k/$500k exclusion applies to your main home only, not a vacation property. And because it's personal-use property, a loss on the sale isn't deductible either.
The exclusion that protected your primary residence doesn't apply to a vacation property. For a true second home, the full gain is usually taxable — and that surprises most sellers. Unlike a rental, a personal-use second home also gives you no depreciation offsets to reduce the bill.
Per the IRS rules on selling your home, the exclusion is tied to a home being your MAIN residence. A property you visit on weekends and holidays — but never made your principal home — doesn't meet the use test.
The exclusion is off the table for a true second home. Four other levers still work:
Improvements over the years — a renovated kitchen, a new deck, a finished basement — add to basis and lower the taxable gain. Closing costs and selling expenses count too. Owners who never tracked improvements routinely overpay.
Owned more than a year, the gain is long-term and taxed at 0, 15, or 20% — instead of your ordinary income tax rate. One day matters here (closing date vs anniversary). Higher earners also add 3.8% NIIT on the investment gain.
If the property was GENUINELY converted to your main home (2 of 5 year rule) or a rental (for a meaningful period), different rules apply — each with its own conditions, limits, and nonqualified-use rules. Conversion tactics have to be planned and documented, not backdated.
The gain stacks on your other income for the year. Sell in a lower-income year (retirement, gap year, sabbatical) and more of the gain falls in the 0% or 15% band instead of 20% + NIIT. Timing beats optimization for most sellers.
Many 'second homes' are not purely personal. If you rented it part of the year, listed it on Airbnb/Vrbo, or lived in it for a stretch — the tax treatment changes. Partial exclusion, depreciation recapture, or nonqualified-use limits can all apply.
For any year the property was rented, depreciation was allowable (whether you took it or not) — and gets recaptured at up to 25%. See capital gains tax on investment property for the recapture math.
Sale price − adjusted basis (with improvements + closing costs) = gain. Apply rate band. Add NIIT if applicable. Subtract nothing — no exclusion applies. See capital gains tax planning for how this fits alongside your other 2026 income.
The tax planning that helps a second home is different from a main home. Because the exclusion doesn't apply, basis reconstruction and rate-band timing become the main levers. Owners who overpay usually paid because they didn't track improvements or sold in a peak-income year.
Your fee depends on the work involved, not hours billed. Three things move it: whether the use was purely personal (cleaner return); whether any rental use adds basis and recapture work; whether more than one state taxes the gain (property in FL, primary residence in CA — both may want their cut).

The exclusion is tied to a home being your MAIN residence, per the IRS use test. To claim it, you generally must have OWNED the property AND LIVED in it as your principal home for at least 2 of the 5 years before the sale. Three common misconceptions:
Sources: IRS Topic 701 (home-sale exclusion + main-home use test); Topic 409 (no deductible loss on personal-use property); Publication 523
A good fit if:
Selling your MAIN home instead? See capital gains tax on real estate sale — the $250k/$500k exclusion applies. Renting the property? capital gains tax on investment property covers the depreciation recapture layer. Or the full framework: capital gains tax planning.
Capital gains tax on a second home depends on the details: what you paid, the sale price, how you used the place, and any improvements. The more precise those are, the tighter the answer. From there we give you the taxable gain and what legitimately brings it down.
"You just sold a home and you know you have capital gains. You just got married and you don't know what your taxes are going to look like with your spouse. Plan early because if you don't there might be a surprise."
