Investing in real estate remains one of the most popular wealth-building strategies in the United States, but every property investor needs a solid understanding of property tax in the United States and, more specifically, how capital gains tax on property in the United States works. Whether you're a domestic investor flipping houses, a long-term landlord selling a rental property, or a foreign national with U.S. real estate holdings, the tax implications of selling property can significantly affect your bottom line.
In this comprehensive guide, we break down everything you need to know about real estate investment United States tax obligations for the 2025/2026 tax year—including current rates, exemptions, strategies to minimize your liability, and special rules for non-residents.
What Is Capital Gains Tax on Property?
Capital gains tax is a federal (and often state) tax levied on the profit you make when you sell a capital asset—including real estate—for more than you paid for it. The "gain" is the difference between your adjusted basis (typically the purchase price plus certain costs and improvements) and the net sale price (the selling price minus selling expenses).
Simple formula:
Capital Gain = Net Sale Price − Adjusted Basis
For example, if you purchased a property for $300,000, spent $50,000 on qualifying improvements, and sold it for $500,000 with $30,000 in selling costs:
- Adjusted Basis = $300,000 + $50,000 = $350,000
- Net Sale Price = $500,000 − $30,000 = $470,000
- Capital Gain = $470,000 − $350,000 = $120,000

Short-Term vs. Long-Term Capital Gains
The IRS distinguishes between two types of capital gains based on how long you held the property:
- Short-term capital gains: Property held for one year or less. Taxed as ordinary income at your marginal federal income tax rate (up to 37% for 2025).
- Long-term capital gains: Property held for more than one year. Taxed at preferential rates of 0%, 15%, or 20%, depending on your taxable income.
Because real estate transactions often involve substantial sums, the difference between short-term and long-term treatment can mean tens of thousands of dollars in tax savings.
2025/2026 Capital Gains Tax Rates for Property Sales
For the 2025 tax year (returns filed in 2026), the federal long-term capital gains tax rates are as follows:
Long-Term Capital Gains Tax Brackets — Single Filers (2025)
| Taxable Income | Long-Term Capital Gains Rate |
|---|---|
| Up to $48,350 | 0% |
| $48,351 – $533,400 | 15% |
| Over $533,400 | 20% |
Long-Term Capital Gains Tax Brackets — Married Filing Jointly (2025)
| Taxable Income | Long-Term Capital Gains Rate |
|---|---|
| Up to $96,700 | 0% |
| $96,701 – $600,050 | 15% |
| Over $600,050 | 20% |
The Net Investment Income Tax (NIIT)
High-income taxpayers may also owe an additional 3.8% Net Investment Income Tax (also known as the Medicare surtax) on capital gains. This applies to:
- Single filers with modified adjusted gross income (MAGI) above $200,000
- Married couples filing jointly with MAGI above $250,000
This means the effective maximum federal rate on long-term capital gains from property can reach 23.8% (20% + 3.8%).
Depreciation Recapture
If you claimed depreciation deductions on a rental or investment property, the IRS requires you to "recapture" that depreciation when you sell. Depreciation recapture is taxed at a flat rate of 25%, regardless of your income bracket. This is a frequently overlooked aspect of capital gains tax property United States rules and can come as an unpleasant surprise to investors who haven't planned for it.
Example: You purchased a rental property for $400,000 (with $320,000 allocated to the building) and claimed $80,000 in depreciation over your holding period. When you sell, that $80,000 is subject to the 25% depreciation recapture rate ($20,000 in tax), while the remaining gain is taxed at the applicable long-term capital gains rate.

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.
Eligibility Requirements
To qualify for the exclusion, you must meet the ownership and use tests:
- Ownership Test: You must have owned the home for at least 2 of the 5 years preceding the sale.
- Use Test: You must have lived in the home as your primary residence for at least 2 of the 5 years preceding the sale.
- Frequency Limit: You cannot have used the exclusion on another home sale within the 2 years preceding the current sale.
The 2-year periods for ownership and use do not need to be concurrent, and partial exclusions may be available if you moved due to health, work, or other unforeseen circumstances.
Exclusion Amounts for 2025
- Single filers: Up to $250,000 in capital gains excluded
- Married filing jointly: Up to $500,000 in capital gains excluded (both spouses must meet the use test; only one needs to meet the ownership test)
Example: A married couple purchased their home for $350,000, lived in it for 8 years, and sold it for $800,000. Their capital gain is $450,000. Because they file jointly and meet all requirements, the entire $450,000 gain is excluded from federal income tax—resulting in zero capital gains tax on the sale.
This exclusion is one of the most significant tax advantages in the U.S. tax code, and understanding it is crucial for anyone considering real estate investment United States tax planning.
1031 Like-Kind Exchange: Deferring Capital Gains Tax
For investment and business properties (not primary residences), a Section 1031 like-kind exchange allows you to defer capital gains tax indefinitely by reinvesting the proceeds into a similar property.
Key Rules for a 1031 Exchange
- The property sold and the property acquired must both be held for investment or business use.
- The replacement property must be of "like-kind"—which, for real estate, is interpreted broadly (e.g., you can exchange a residential rental for commercial property).
- You must identify the replacement property within 45 days of closing the sale.
- You must close on the replacement property within 180 days of the original sale.
- A qualified intermediary must hold the funds during the exchange; you cannot touch the proceeds directly.
- Any cash or non-like-kind property received (called "boot") is taxable.
Strategic Benefits
A 1031 exchange doesn't eliminate capital gains tax—it defers it. However, savvy investors use sequential 1031 exchanges to defer taxes across multiple transactions over decades. If the property is eventually inherited, the heirs receive a stepped-up basis, potentially eliminating the deferred gain entirely.
Common mistake: Many investors attempt DIY 1031 exchanges without a qualified intermediary or miss the strict 45-day and 180-day deadlines, inadvertently triggering a fully taxable event. Always work with experienced professionals for these transactions.
State-Level Capital Gains Taxes on Property
Federal tax is only part of the equation. Most U.S. states also tax capital gains from property sales, and rates vary dramatically:
- No state income tax (and thus no state capital gains tax): Alaska, Florida, Nevada, New Hampshire (on earned income only), South Dakota, Tennessee, Texas, Washington (though Washington imposes a 7% tax on long-term capital gains exceeding $270,000 for 2025), and Wyoming.
- High state capital gains tax states: California (up to 13.3%), New York (up to 10.9%), New Jersey (up to 10.75%), Hawaii (up to 11%), and Oregon (up to 9.9%).
When planning a property sale, your combined federal and state tax burden could range from roughly 15% to over 37% depending on your income, filing status, and state of residence.

Capital Gains Tax for Non-Residents and Foreign Investors
Foreign nationals who invest in U.S. real estate face unique tax rules under the Foreign Investment in Real Property Tax Act (FIRPTA).
How FIRPTA Works
- When a non-resident alien 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.
- The withholding rate is 10% if the sale price is between $300,001 and $1,000,000 and the buyer intends to use the property as a residence.
- No withholding is required if the sale price is $300,000 or less and the buyer will use the property as a residence.
- The seller can file a U.S. tax return to report the actual gain and claim a refund if the withholding exceeded the actual tax liability.
Tax Treaty Considerations
The United States has income tax treaties with over 60 countries. While most treaties do not override FIRPTA withholding (the U.S. generally reserves the right to tax gains from real property), treaties can affect:
- The overall tax rate on the gain
- Credits available in your home country for U.S. taxes paid
- Reporting requirements
For example, a UK resident selling U.S. property will pay U.S. capital gains tax under FIRPTA but can generally claim a foreign tax credit in the UK to avoid double taxation, per the U.S.-UK tax treaty.
Important: Non-resident investors should file Form 1040-NR to report U.S. real estate dispositions and potentially recover excess FIRPTA withholding.
Strategies to Minimize Capital Gains Tax on U.S. Property
Legal tax planning can substantially reduce your capital gains tax liability. Here are the most effective strategies for 2025/2026:
1. Hold Property for More Than One Year
The simplest strategy: ensure your holding period exceeds 12 months to qualify for long-term capital gains rates (0%–20%) instead of short-term rates (up to 37%).
2. Maximize Your Adjusted Basis
Keep meticulous records of all capital improvements (new roof, renovations, additions) and acquisition costs (closing costs, title insurance, transfer taxes). These increase your basis and reduce your taxable gain.
Costs that increase your basis include:
- Home improvements and renovations
- Legal and title fees at purchase
- Impact fees and zoning costs
- Assessment for local improvements (sidewalks, roads)
3. Use the Primary Residence Exclusion Strategically
If you're converting a rental property to a primary residence, live in it for at least 2 years before selling to qualify for the Section 121 exclusion. Note: gains allocable to periods of non-qualified use after 2008 may not be excludable.
4. Execute a 1031 Exchange
As discussed above, defer gains by reinvesting in like-kind property. This is particularly powerful for building a real estate portfolio over time.
5. Harvest Capital Losses
If you have other investments that have declined in value, selling them in the same tax year can offset your property gains. You can offset unlimited capital gains with capital losses, plus deduct up to $3,000 in net capital losses against ordinary income annually.
6. Consider Installment Sales
Selling property on an installment basis (receiving payments over multiple years) spreads the gain across tax years, potentially keeping you in lower tax brackets each year. This is reported on IRS Form 6252.
7. Donate to Charity or Use Opportunity Zones
Investing capital gains in a Qualified Opportunity Zone (QOZ) fund can defer and potentially reduce capital gains tax. While the original 10% and 15% basis step-ups for QOZ investments expired for new investments, gains from QOZ investments held for 10+ years may still be excluded from tax on the QOZ investment's appreciation.
Frequently Asked Questions
How much capital gains tax will I pay when I sell my house in the United States?
It depends on your filing status, income, holding period, and whether the property is your primary residence. Long-term capital gains are taxed at 0%, 15%, or 20% federally (plus potentially 3.8% NIIT), while short-term gains are taxed as ordinary income. Primary residence sellers may exclude up to $250,000 ($500,000 for married couples). Use our United States Capital Gains Tax Calculator for a personalized estimate.
Do I have to pay capital gains tax if I reinvest in another property?
Not necessarily. If you execute a proper 1031 like-kind exchange for investment or business property, you can defer the tax. However, this does not apply to primary residences, and strict timelines and rules must be followed.
Are non-U.S. citizens subject to capital gains tax on U.S. property?
Yes. Under FIRPTA, foreign sellers of U.S. real property are subject to capital gains tax and mandatory withholding. Tax treaties may provide relief from double taxation but generally do not exempt the U.S. tax itself.
What is the capital gains tax rate for 2025 in the United States?
For 2025, long-term capital gains rates are 0%, 15%, or 20% depending on taxable income. An additional 3.8% NIIT may apply to high earners. Short-term gains are taxed at ordinary income rates up to 37%. Depreciation recapture on real property is taxed at 25%.
Can I deduct home improvement costs to reduce my capital gains?
Yes. Capital improvements—but not routine repairs and maintenance—increase your property's adjusted basis, which reduces your capital gain when you sell. Keep all receipts and documentation.
