Airbnb Capital Gains Tax: Rates, Recapture, and 1031 Exchanges

When you sell an Airbnb property, the Airbnb capital gains tax you owe is really three taxes stacked together: a long-term capital gains rate of 0%, 15%, or 20% on your profit; a separate 25% rate on the depreciation you claimed (or could have claimed) while renting the place out; and, for higher earners, an additional 3.8% Net Investment Income Tax on top of both. How big each layer gets depends on how long you owned the property, whether you ever lived in it, how much you depreciated, and your income in the year of sale.

How Long You Owned It Sets the Rate on Your Profit

Sell within one year of buying and any profit is a short-term capital gain, taxed at your ordinary income rate, which can land anywhere from 10% to 37%.¹

Hold longer than a year and the profit qualifies for long-term capital gains rates: 0%, 15%, or 20%, based on your total taxable income.¹ For 2026, single filers pay 0% on long-term gains up to $49,450 of taxable income, 15% between $49,450 and $545,500, and 20% above $545,500. Married couples filing jointly hit the 15% bracket at $98,900 and the 20% bracket at $613,700. Most sellers land in the 15% tier, but a large gain from a property sale can push you into 20% even if your wages alone wouldn’t.

Depreciation Recapture Is Where the Bill Gets Bigger

This is the layer most Airbnb sellers underestimate. While the property was a rental, you were entitled to depreciate the building’s value over 27.5 years on a straight-line basis.² Those annual deductions reduced your taxable rental income year after year. When you sell, the IRS wants that benefit back.

The total depreciation gets taxed as “unrecaptured Section 1250 gain” at a maximum rate of 25%, on top of the long-term capital gains rate that applies to the rest of your profit.³ On a property depreciated for ten years, that recapture can easily run into five figures.

Now the part that stings. The IRS reduces your cost basis by the depreciation that was “allowed or allowable,” not just what you actually claimed.⁴ If you forgot to take depreciation for several years, you still owe recapture on what you could have deducted. You got none of the yearly benefit but owe the full recapture bill at sale. Depreciation on a rental is not optional, and skipping it is one of the most expensive mistakes a host can make.

The 3.8% Surtax for Higher Earners

The Net Investment Income Tax adds another 3.8% on top of your capital gains and recapture bill when modified adjusted gross income exceeds $200,000 for single filers, $250,000 for married couples filing jointly, or $125,000 for married filing separately.⁵ These thresholds are not indexed for inflation, so they pull in more taxpayers each year.

The 3.8% applies to the lesser of your net investment income or the amount by which your income exceeds the threshold.⁵ For most Airbnb hosts, rental income and gains count as passive income and fall squarely within the NIIT. Escaping it requires qualifying as a real estate professional who materially participates in the rental, a high bar that few casual hosts clear. Stacked with the 20% long-term rate and the 25% recapture rate, the surtax pushes the effective top rate on different portions of your gain to 23.8% or 28.8%.

Calculating Your Adjusted Basis

Your taxable gain is not the sale price minus what you paid. The IRS uses an “adjusted basis” that accounts for improvements, selling costs, and depreciation. Getting this number right is the single biggest lever you have to reduce the bill.

Start with the original purchase price, including settlement costs like title insurance and recording fees. Add capital improvements: a new roof, kitchen renovation, an added bathroom, a replaced HVAC system, a new deck. Anything that adds value or extends useful life qualifies. Routine maintenance, like patching drywall or replacing a faucet, does not; those were operating expenses you should have deducted in the year you paid them.⁴

Then subtract the total depreciation allowed or allowable over the life of the rental, and subtract selling costs such as agent commissions, legal fees, and transfer taxes.⁴ The result is your adjusted basis. Sale price minus adjusted basis equals your total gain, which then splits between the recapture piece (up to 25%) and the remaining capital gain (at your long-term or short-term rate).

Keep every receipt and contractor invoice from the day you buy. Hosts who cannot document improvements end up with a lower basis and a bigger tax bill, and there is no retroactive fix for missing records.

If You Also Lived in the Property

Section 121 of the Internal Revenue Code lets single filers exclude up to $250,000 of gain and joint filers up to $500,000 when they sell a primary residence.⁶ To qualify you must have owned the home and used it as your main residence for at least two of the five years before the sale. The two years don’t need to be consecutive.⁷

The exclusion never covers depreciation recapture. That layer is always taxable, regardless of how the exclusion applies to the rest of the gain.

Nonqualified Use When Rental Came First

Any period after 2008 when the property was a rental before becoming your primary residence counts as “nonqualified use.” The IRS allocates a portion of the gain to that period, and the exclusion does not cover it.⁶ Owned it for ten years, rented it for three before moving in, lived there seven? Roughly 30% of the gain stays taxable.

Rental use after the property was your primary residence is specifically excluded from the nonqualified use calculation.⁶ So if you lived in the home five years, converted it to an Airbnb for two, and sold within the five-year window, the full exclusion can still apply to the gain, minus depreciation recapture.

A Room in Your Home Versus a Separate Unit

Renting a spare bedroom inside your dwelling through Airbnb generally does not force you to split the gain between business and personal use. The full exclusion can apply to the entire gain, though you still owe recapture on any depreciation claimed.⁸

A detached guest house, a converted garage apartment, or a separate rental unit on the same lot is treated as a separate portion, and Section 121 typically does not apply to the gain allocable to it. You would need to have owned and lived in that separate structure for at least two of the five years before the sale, which rarely happens with a dedicated rental.⁸ The gain on that portion is reported as a business property sale.

Suspended Passive Losses Get Released at Sale

Many Airbnb hosts carry passive losses they were never able to use. When rental expenses exceeded rental income and you didn’t qualify for the active participation exception, the loss was suspended rather than deducted. A complete taxable disposition of the property releases all suspended passive losses at once.⁹

Those freed losses can offset the gain from the sale and even spill over to reduce other income. Years of carried-forward losses can produce a substantial offset. Track them on Form 8582 each year so you know exactly what’s coming into the year of sale.¹⁰ One catch: the sale must be to an unrelated party. Selling to a family member or related entity delays the release until that person sells to someone outside the family.⁹

Deferring the Tax With a 1031 Exchange

If you’re staying in real estate, a like-kind exchange under Section 1031 lets you roll the gain into a replacement investment property and defer the tax indefinitely. The replacement must also be held for productive use in a business or for investment; you can’t exchange into a personal vacation home.¹¹

Two deadlines run from the day you transfer the old property, and neither can be extended for convenience:

Within 45 days, identify potential replacement properties in writing.
Within 180 days, or by the due date of your return for the year of the exchange including extensions (whichever is earlier), close on the replacement.

Miss either and the entire exchange fails, leaving you with a fully taxable sale.¹¹

You also cannot touch the sale proceeds. A qualified intermediary, an independent third party, must hold the funds between the sale of the old property and the purchase of the new one. If the money passes through your hands or your agent’s, the IRS treats it as a completed sale with no deferral.¹² The intermediary can’t be someone who served as your accountant, attorney, or real estate agent within the prior two years.

A 1031 defers the tax; it doesn’t erase it. The replacement property carries over the original basis and depreciation history, so if you eventually sell without another exchange, the accumulated tax comes due.

Forms You’ll File

An Airbnb sale usually touches several forms, filed with your standard Form 1040.

Form 4797 reports the sale of the rental and calculates the depreciation recapture in Part III.¹³
Form 8949 and Schedule D handle any gain above the recapture amount, taxed at your applicable capital gains rate.¹⁴
Form 8582 documents suspended passive losses and their release against the gain.¹⁰
Form 6252 spreads the gain across multiple years if you structured the sale as an installment agreement.¹⁵

Hold on to the original closing statement, every capital improvement receipt, all depreciation schedules, and the closing statement from the sale. These are the records that back up your basis if the IRS ever asks.
