Capital Gains Tax When Selling an Airbnb Property: What STR Investors Need to Know

Picture this: you bought an Airbnb property five years ago for $400,000. You reported depreciation every single year like the good taxpayer you are. Now you have a buyer at $550,000, and you have already started spending your $150,000 profit in your head. Then your accountant calls with a math problem you did not see coming.

What most STR investors discover at that moment is that selling a short-term rental property is not like selling a primary home. Two separate tax calculations apply to the same transaction, each with different rates, different rules, and a combined bill that can consume a third or more of what looks like a clean profit. The number that tends to produce the most memorable conference calls with CPAs is depreciation recapture, which is the IRS mechanism that takes back the tax benefit you received while you owned the property.

This guide walks through both taxes, shows the math on a real-numbers example, covers how state taxes change the picture, and lays out the strategies worth exploring before you sign a listing agreement.

The Two Taxes STR Sellers Face

When you sell a short-term rental property, the IRS sees two separate pools of gain, and they are taxed differently.

The first is capital gains tax on the appreciation. This is the difference between what you paid for the property (your adjusted cost basis) and what you sold it for, minus the portion attributable to depreciation. Long-term capital gains rates (for property held more than one year) are 0%, 15%, or 20% depending on your income. For most investors selling a rental property, 15% is the applicable rate. High earners above the top threshold pay 20%. For the 2026 tax year, the 20% rate kicks in above approximately $533,400 in taxable income for single filers and $613,700 for married couples filing jointly, per IRS inflation adjustments for 2026.

The second is depreciation recapture under IRS Section 1250, and this is the one that catches investors off guard. While you owned the property, you deducted depreciation against your income each year. The IRS allowed that deduction on the theory that the building was wearing out. When you sell, the IRS recaptures those deductions by taxing that portion of the gain at a flat 25% federal rate regardless of your income bracket. You do not get the benefit of a lower capital gains rate on the depreciation piece. It is taxed at 25%. Period.

For high-income investors, there is a third layer: the Net Investment Income Tax (NIIT). A 3.8% surtax applies to net investment income for taxpayers whose modified adjusted gross income exceeds $200,000 (single) or $250,000 (married filing jointly). Rental income and capital gains from rental property both count as net investment income. If your income crosses those thresholds in the year of sale, the 3.8% applies to the gain.

How Depreciation Recapture Works

When you own a residential rental property, the IRS lets you depreciate the structure (not the land) over 27.5 years using straight-line depreciation per IRS Publication 946. On a $400,000 purchase where the land is valued at $50,000, the depreciable basis is $350,000. Divide by 27.5 years and you get annual depreciation of approximately $12,727. Over five years, that is roughly $63,636 in total depreciation deductions.

Here is the part that matters for the sale: when you sell, the IRS does not simply compare what you paid to what you received. It compares your adjusted cost basis to what you received. Your adjusted cost basis is your original purchase price minus the total accumulated depreciation you claimed, or were allowed to claim even if you did not actually take the deduction. The IRS tracks this either way.

So if you paid $400,000, depreciated $60,000, and sold for $550,000:

• Adjusted cost basis: $400,000 minus $60,000 equals $340,000
• Total gain: $550,000 minus $340,000 equals $210,000

That $210,000 gain is not all taxed the same way. The depreciation piece ($60,000) is recaptured at 25% under Section 1250. The remaining $150,000 is taxed at long-term capital gains rates, assuming you held the property more than one year. The IRS form where this plays out is Form 4797 (Sales of Business Property), which you file alongside Schedule D.

One critical parenthetical: “allowed to claim” means the IRS will recapture depreciation even if you forgot to take it. If you did not claim depreciation for two years, the IRS still treats those deductions as having been taken. The allowed-or-allowable depreciation rule means you bear the tax cost regardless of whether you actually captured the annual deduction. Take the deductions.

Calculating Your Capital Gains: A Real-Numbers Example

Here is the full calculation on a concrete scenario: property bought for $400,000, depreciated $60,000 over the holding period, sold for $550,000. The seller is married, filing jointly, with $175,000 in other taxable income, putting them in the 15% long-term capital gains bracket, but potentially crossing the NIIT threshold once the gain is added.

Step 1: Determine adjusted cost basis
$400,000 (purchase price) minus $60,000 (accumulated depreciation) equals $340,000 adjusted cost basis.

Step 2: Calculate total gain
$550,000 (sale price) minus $340,000 (adjusted basis) equals $210,000 total gain.

Step 3: Split the gain
Depreciation recapture gain: $60,000 taxed at 25% per Section 1250
Long-term capital gain: $150,000 taxed at 15% for this bracket

Step 4: Calculate the federal tax
Depreciation recapture: $60,000 times 25% equals $15,000
Capital gains tax: $150,000 times 15% equals $22,500
Total federal tax on the gain: $37,500

Step 5: Check for NIIT
Adding $210,000 in gain to the couple’s $175,000 in other income produces $385,000 in modified adjusted gross income for the year, which exceeds the $250,000 MFJ threshold. The NIIT applies to the net investment income portion above the threshold.
NIIT estimate: $210,000 times 3.8% equals $7,980

Total federal tax bill from this sale: approximately $45,480

Add state taxes and selling costs, and the investor’s $150,000 in apparent appreciation looks considerably different in the net column. This is not a reason to avoid selling a good asset at the right time. But $45,480 in federal taxes on what felt like a $150,000 gain is exactly the kind of number that warrants a conversation with a CPA before you are signing a closing disclosure.

State Capital Gains Tax Variation

Federal taxes are only part of the bill. Most states also tax capital gains, and the variation across popular STR markets is significant enough to change your exit math by tens of thousands of dollars.

No state capital gains tax: Florida, Texas, Nevada, Wyoming, Tennessee, and Alaska have no state income tax and therefore no state capital gains tax. Sellers in Florida’s Gulf Coast markets, the Smoky Mountains of Tennessee, or the Las Vegas area do not pay state tax on the gain. This is a meaningful advantage that explains why some investors deliberately target no-income-tax states when building STR portfolios.

California: California taxes capital gains as ordinary income, with state rates reaching 13.3% at the top bracket. On the $210,000 gain from the example above, a California taxpayer in the top bracket could owe an additional $27,930 in state taxes. Combined with the federal calculation, the total tax bill approaches $73,000 on a transaction that produced $150,000 in appreciation. The effective rate on the appreciation piece alone approaches 49% for high earners in California. (I know. Take a breath.)

North Carolina: A flat 3.99% income tax rate for 2026 applies to capital gains (the rate dropped from 4.5% in 2025 as part of the state’s scheduled reductions). Relevant for investors in Outer Banks, Asheville, or other popular North Carolina STR markets.

Colorado: Colorado taxes capital gains as ordinary income at a flat 4.4% for 2026, following recent rate reductions. Active in Breckenridge, Telluride, Vail, and other ski-town STR markets.

New York: New York State taxes capital gains as ordinary income at rates up to 10.9%, with an additional city surcharge of up to 3.876% for New York City residents. Selling an STR in New York City while living there can produce a combined city-state-federal effective rate that exceeds 50% on the gain.

The property location (not where you live) generally determines your state tax on real estate sales. Multi-state situations can get complicated and are worth a specific conversation with a CPA who handles real estate investors across state lines.

Strategies to Minimize the Tax Hit

There are legitimate, IRS-approved strategies for reducing the capital gains tax when selling an Airbnb property. None of them work at the closing table. They all require planning in advance, which is why understanding your exit tax profile before you buy is valuable, not just the week you list.

1031 Exchange

A 1031 exchange (named for IRC Section 1031) allows you to defer capital gains and depreciation recapture taxes by reinvesting the proceeds into a like-kind replacement property. If done correctly, you pay zero tax at sale and the deferred gain carries into the new property by adjusting its cost basis downward. The key rules: you must identify a replacement property within 45 days of closing the sale and close on the replacement within 180 days. The exchange must be structured through a qualified intermediary. You cannot receive the proceeds directly or the exchange fails.

A 1031 exchange defers the tax; it does not eliminate it. The deferred gain eventually comes due when you sell the replacement property without another exchange. Many investors execute a series of exchanges over decades and plan the final property disposition to occur at death, where heirs receive a stepped-up basis that effectively bypasses the accumulated deferred gain. For the full requirements specific to short-term rentals, see our complete guide: 1031 Exchange for Short-Term Rentals.

Installment Sale

Under IRS Publication 537, you can structure the sale as an installment sale by accepting payments from the buyer over time rather than a lump sum at closing. You recognize gain only as you receive payments, spreading the tax liability across multiple tax years. This can reduce your marginal rate in any single year and potentially keep you below the NIIT threshold.

The catch: depreciation recapture must be reported as income in the year of sale, regardless of when you receive the payments. The recapture cannot be spread across years. But the capital gains portion can be spread meaningfully, which is useful for investors who do not need the full proceeds immediately and want to reduce the tax hit in the year of sale.

Opportunity Zone Investment

Capital gains invested in a Qualified Opportunity Fund (QOF) within 180 days of the sale can be deferred under the opportunity zone rules. If you hold the QOF interest for 10 years, gains on the QOF investment itself are excluded from federal taxes entirely under current law. This strategy requires investing in projects located in designated low-income opportunity zones, which limits the universe of available investments but can be compelling for investors with large capital gains who also want long-term exposure to those markets.

Tax-Loss Harvesting

If you have capital losses from other investments (stock positions, other properties, business assets) that can be realized in the same tax year, those losses offset capital gains dollar for dollar. Coordinating the sale timing with other portfolio activity can meaningfully reduce the net taxable gain in a given year. This requires knowing your estimated full-year tax situation before you decide when to close.

Timing and Bracket Management

Selling in a year when your other income is lower (during a year of partial retirement, a career transition, or reduced business income) can drop your capital gains rate from 20% to 15%, or in qualifying circumstances to 0%. The depreciation recapture is always 25% regardless of brackets, but a 5% savings on a $150,000 gain is $7,500 in real money. Bracket management requires knowing your estimated tax situation 12 months out, which is exactly why CPAs who specialize in real estate investors prefer to meet with you annually, not just at tax time.

When to Talk to a CPA

The honest answer is: before you buy the property, not when you are ready to sell it.

The investors who handle the exit tax well almost always set up their depreciation schedule carefully from day one, considered cost segregation studies where the economics made sense, and had a general exit framework in mind when they structured the original purchase. The investors who get surprised by a $45,000 federal tax bill on what looked like a $150,000 gain are the ones who treated depreciation as a pleasant annual bonus without understanding what it means for the eventual sale.

Specifically, involve a CPA when:

• You are under contract on an STR purchase and want to model the eventual exit tax before you even close on the buy
• You are 12 to 24 months from a potential sale and want time to evaluate the 1031 exchange, installment sale, or opportunity zone options
• Your property has appreciated significantly and you own it in a high-tax state
• You have multiple STRs and want to coordinate the timing of sales across your portfolio
• You completed a cost segregation study, which front-loads depreciation into early years and increases the eventual recapture amount at sale

Find a CPA who specifically works with real estate investors, not a generalist. The IRS forms involved (Form 4797 for the sale, Schedule D for capital gains, Form 6252 for installment sales, Form 8824 for 1031 exchanges) are not exotic, but the planning around timing, holding periods, and tax minimization requires someone who handles these situations regularly.
