If you're considering a property investment in the United States, understanding the capital gains tax on property is one of the most important steps you can take to protect your returns. Whether you're a U.S. resident selling your primary home, an investor offloading a rental property, or a non-resident with real estate holdings in America, the capital gains tax rules for 2025/2026 will directly impact your bottom line.
The U.S. real estate market remains one of the largest and most active in the world, attracting both domestic and international investors. But with opportunity comes tax obligation. In this comprehensive guide, we'll walk you through everything you need to know about real estate investment United States tax rules — from how gains are calculated to the exemptions and strategies that can save you thousands of dollars.
What Is Capital Gains Tax on Property in the United States?
Capital gains tax is a federal (and often state) tax levied on the profit you make when you sell an asset — including real estate — for more than you originally paid. In the context of property tax in the United States, capital gains tax is distinct from annual property taxes assessed by local governments. Instead, it applies only at the point of sale, when a gain is realized.
How Capital Gains Are Calculated
Your capital gain on a property sale is calculated as follows:
Capital Gain = Sale Price − Adjusted Cost Basis
The adjusted cost basis includes:
- The original purchase price of the property
- Closing costs paid at purchase (e.g., title insurance, legal fees)
- The cost of capital improvements (e.g., a new roof, kitchen renovation, room addition)
- Certain selling expenses (e.g., real estate agent commissions, transfer taxes)
Example: You purchased a rental property in Texas for $300,000, paid $8,000 in closing costs, and spent $40,000 on capital improvements over the years. Your adjusted cost basis is $348,000. If you sell the property for $500,000 and pay $30,000 in selling expenses, your capital gain is:
$500,000 − $348,000 − $30,000 = $122,000

Short-Term vs. Long-Term Capital Gains Tax Rates for 2025/2026
The U.S. tax code distinguishes between short-term and long-term capital gains, and the difference has a significant impact on how much tax you'll owe.
Short-Term Capital Gains
If you sell a property you've owned for one year or less, the profit is classified as a short-term capital gain. Short-term gains are taxed as ordinary income, meaning they're added to your other income and taxed at your marginal income tax rate.
For the 2025 tax year, federal ordinary income tax brackets for single filers are:
| Taxable Income | Tax Rate |
|---|---|
| Up to $11,925 | 10% |
| $11,926 – $48,475 | 12% |
| $48,476 – $103,350 | 22% |
| $103,351 – $197,300 | 24% |
| $197,301 – $250,525 | 32% |
| $250,526 – $626,350 | 35% |
| Over $626,350 | 37% |
This means a short-term gain on a property flip could be taxed at rates as high as 37% at the federal level.
Long-Term Capital Gains
If you hold the property for more than one year before selling, the gain qualifies as a long-term capital gain and receives preferential tax treatment. The 2025 long-term capital gains tax rates are:
| Filing Status | 0% Rate | 15% Rate | 20% Rate |
|---|---|---|---|
| Single | Up to $48,350 | $48,351 – $533,400 | Over $533,400 |
| Married Filing Jointly | Up to $96,700 | $96,701 – $600,050 | Over $600,050 |
| Head of Household | Up to $64,750 | $64,751 – $566,700 | Over $566,700 |
Most property investors will fall into the 15% bracket, though high-income sellers may face the 20% rate.
The Net Investment Income Tax (NIIT)
In addition to the standard capital gains rates, high earners may owe an additional 3.8% Net Investment Income Tax (NIIT). This surtax applies to the lesser of your net investment income or the amount by which your modified adjusted gross income (MAGI) exceeds:
- $200,000 for single filers
- $250,000 for married filing jointly
This means the effective maximum federal rate on long-term capital gains from property can reach 23.8% (20% + 3.8%).

The Primary Residence Exclusion: Section 121
One of the most powerful tax benefits available to U.S. homeowners is the Section 121 exclusion, which allows you to exclude a significant portion of capital gains from the sale of your primary residence.
Exclusion Amounts
- Single filers: Up to $250,000 in capital gains excluded
- Married filing jointly: Up to $500,000 in capital gains excluded
Eligibility Requirements
To qualify for the full exclusion, you must meet the ownership and use tests:
- Ownership Test: You must have owned the property for at least 2 of the 5 years preceding the sale.
- Use Test: You must have lived in the property as your primary residence for at least 2 of the 5 years preceding the sale.
- Frequency Limitation: You cannot have claimed the exclusion on another home sale within the 2 years before the current sale.
The two years do not need to be consecutive. Partial exclusions may be available if you fail to meet the full requirements due to a change in employment, health reasons, or other unforeseen circumstances.
Example: A married couple purchased their home in 2019 for $400,000 and sells it in 2025 for $850,000. After accounting for $50,000 in improvements and $50,000 in selling costs, their capital gain is $350,000. Since this is below the $500,000 married filing jointly exclusion, they owe $0 in federal capital gains tax on the sale.
This exclusion is one of the most commonly overlooked benefits in real estate investment United States tax planning — but it applies only to primary residences, not investment properties.
Capital Gains Tax on Rental and Investment Properties
Investment properties — including rental homes, vacation properties, and commercial real estate — do not qualify for the Section 121 exclusion. Gains on these properties are fully taxable, and sellers may also face depreciation recapture.
Depreciation Recapture
If you've claimed depreciation deductions on a rental property (as most landlords do), the IRS requires you to "recapture" that depreciation when you sell. Depreciation recapture is taxed at a maximum federal rate of 25%, which is higher than the standard long-term capital gains rate for most taxpayers.
Example: You purchased a rental property for $350,000 (with $50,000 allocated to land, which is not depreciable, and $300,000 to the building). Over 10 years, you claimed $109,090 in depreciation. When you sell for $500,000, your gain includes:
- Depreciation recapture: $109,090 taxed at up to 25%
- Remaining capital gain: Taxed at your applicable long-term rate (0%, 15%, or 20%)
This two-layer taxation is a common surprise for first-time investment property sellers.
1031 Like-Kind Exchange: Deferring Capital Gains
One of the most popular strategies for deferring capital gains tax on property in the United States is the Section 1031 like-kind exchange. This provision allows you to defer paying capital gains tax (including depreciation recapture) by reinvesting the proceeds from a property sale into a "like-kind" replacement property.
Key rules for a 1031 exchange:
- Both properties must be held for investment or business use — personal residences and primary homes do not qualify.
- You must identify a replacement property within 45 days of the sale.
- You must close on the replacement property within 180 days of the sale.
- A qualified intermediary must hold the funds between the sale and purchase — you cannot take constructive receipt of the money.
- The replacement property must be of equal or greater value to defer the entire gain.
A properly executed 1031 exchange can allow investors to defer taxes indefinitely, rolling gains from one property to the next throughout their investing career. Upon death, heirs receive a stepped-up cost basis, potentially eliminating the deferred gain entirely.
Capital Gains Tax for Non-Residents and Foreign Investors
Non-resident aliens who invest in U.S. real estate face a unique set of tax rules. Understanding these is critical for anyone making a real estate investment in the United States from abroad.
FIRPTA: The Foreign Investment in Real Property Tax Act
Under FIRPTA, when a foreign person sells U.S. real property, the buyer is generally required to withhold 15% of the gross sale price (not just the gain) and remit it to the IRS. This withholding acts as a prepayment toward the foreign seller's U.S. tax liability.
Key FIRPTA details for 2025:
- Withholding rate: 15% of the gross sale price (10% if the buyer intends to use the property as a residence and the sale price is $1,000,000 or less)
- Exemption: No withholding is required if the sale price is $300,000 or less AND the buyer intends to use the property as a residence
- Filing requirement: Foreign sellers must file a U.S. tax return (Form 1040-NR) to report the gain and claim any overpaid withholding as a refund
Tax Treaty Considerations
The United States has income tax treaties with over 60 countries. While most treaties preserve the U.S. right to tax gains on real property (consistent with the FIRPTA rules), certain treaty provisions may affect:
- The applicable tax rates on other types of U.S.-source income
- Whether certain types of entities are eligible for reduced withholding
- How gains are reported and credited in the investor's home country
Foreign investors should always review the specific tax treaty between the United States and their home country to understand how double taxation is avoided and what credits or deductions may be available.

State-Level Capital Gains Taxes: Don't Forget the Second Layer
Federal taxes are only part of the picture. Most U.S. states also impose their own income taxes on capital gains from real estate sales. State rates vary widely:
- States with no income tax (and no state capital gains tax): Alaska, Florida, Nevada, New Hampshire (on earned income), South Dakota, Tennessee, Texas, Washington (though Washington imposes a 7% tax on long-term capital gains exceeding $270,000 for 2025), and Wyoming
- High-tax states: California (up to 13.3%), New York (up to 10.9%), New Jersey (up to 10.75%), Hawaii (up to 11%)
The state where the property is located — not where you live — generally has the right to tax the gain. This means a Florida resident selling a rental property in California will owe California state taxes on the gain.
Local Transfer Taxes
Some cities and counties also impose transfer taxes or mansion taxes on property sales. For example:
- New York City: Transfer tax of 1% to 2.625% depending on sale price, plus a "mansion tax" on properties over $1 million
- Los Angeles: City transfer tax plus the "Measure ULA" tax of 4% on sales over $5 million and 5.5% on sales over $10 million
These additional costs can substantially affect the net proceeds from your investment.
Common Mistakes and Misconceptions
Navigating capital gains tax on property in the United States is complex, and investors frequently make costly errors. Here are the most common:
Failing to track capital improvements: Many homeowners and investors don't keep receipts or records for renovations and improvements. These costs increase your basis and reduce your taxable gain.
Confusing the Section 121 exclusion with investment properties: The primary residence exclusion does not apply to rental homes, second homes, or vacation properties — unless you convert them and meet the ownership and use tests.
Ignoring depreciation recapture: Landlords sometimes forget that the depreciation they claimed (or should have claimed) will be recaptured at up to 25% upon sale.
Missing the 1031 exchange timeline: The 45-day identification period and 180-day closing deadline are strict. Missing either deadline disqualifies the entire exchange.
Overlooking state taxes: Focusing only on federal tax obligations and forgetting about state-level capital gains and transfer taxes can lead to unpleasant surprises at closing.
Non-residents failing to file U.S. tax returns: Foreign investors who have FIRPTA withholding deducted must file a U.S. return to claim any refund. Failure to file means the IRS keeps the full withholding amount.
Not accounting for the NIIT: High-income investors often forget the additional 3.8% surtax when estimating their tax liability.
Frequently Asked Questions
How much capital gains tax will I pay on a property sale in the U.S.?
It depends on your income level, filing status, and how long you owned the property. Long-term capital gains are taxed at 0%, 15%, or 20% at the federal level, plus a potential 3.8% NIIT. Short-term gains are taxed as ordinary income at rates up to 37%. Use our United States Capital Gains Tax Calculator for a personalized estimate.
Can I avoid capital gains tax on my home sale?
If you meet the Section 121 ownership and use tests, you can exclude up to $250,000 (single) or $500,000 (married filing jointly) in gains from the sale of your primary residence.
Do non-U.S. citizens pay capital gains tax on U.S. property?
Yes. Non-resident aliens are subject to U.S. capital gains tax on real property sales under FIRPTA. Buyers typically withhold 15% of the gross sale price, and the seller must file a U.S. tax return to reconcile the actual tax owed.
What is a 1031 exchange and who qualifies?
A 1031 exchange allows investors to defer capital gains tax by reinvesting sale proceeds into a like-kind investment property. It is available to both U.S. residents and non-residents, but the property must be held for investment or business purposes — not personal use.
Are inherited properties subject to capital gains tax?
Inherited properties receive a stepped-up basis equal to the fair market value at the date of the decedent's death. This means if you sell shortly after inheriting, your capital gain (and tax) may be minimal or zero.
