Capital Gains Tax on Real Estate: 2026 Guide

Capital gains tax on real estate applies whenever you sell property for more than your adjusted cost basis—typically what you paid plus qualifying improvements. The IRS treats real estate profits as capital gains, which means the tax treatment depends on how long you owned the property before selling.

Your holding period determines whether gains are classified as short-term or long-term. Properties held for one year or less generate short-term capital gains, taxed at your ordinary income tax rate (10% to 37% in 2026).

Long-term capital gains tax rates for real estate follow three tiers based on your taxable income. These preferential rates are one of the key advantages of holding investment property for more than one year.

For single filers in 2026:

• 0% rate: Taxable income up to $47,025
• 15% rate: Taxable income from $47,026 to $518,900
• 20% rate: Taxable income above $518,900

• 0% rate: Taxable income up to $94,050
• 15% rate: Taxable income from $94,051 to $583,750
• 20% rate: Taxable income above $583,750

These brackets adjust annually for inflation. Note that your taxable income includes the capital gain itself, which can push you into a higher bracket.

Your taxable gain isn't simply the difference between purchase and sale price. The IRS allows you to adjust your cost basis with certain expenses, reducing the amount subject to capital gains tax on real estate.

1. 1Start with the original purchase price
2. 2Add closing costs from purchase (title insurance, legal fees, recording fees)
3. 3Add cost of qualifying improvements (room additions, new roof, HVAC systems)
4. 4Subtract any depreciation claimed (for rental properties)
5. 5Result is your adjusted cost basis

Worked example: You bought a rental property in 2020 for $300,000. Purchase closing costs were $6,000.

• Original purchase: $300,000
• Purchase closing costs: +$6,000
• Improvements: +$15,000 + $8,000 = +$23,000
• Depreciation claimed: -$20,000
• Adjusted basis: $309,000

Selling costs like real estate commissions, transfer taxes, and attorney fees reduce your proceeds. Maintenance and repairs don't increase basis—only permanent improvements that add value or extend the property's life.

The most powerful tax break for capital gains tax on real estate is the Section 121 exclusion for primary residences. Qualifying homeowners can exclude up to $250,000 of gain ($500,000 for married couples filing jointly) from taxation.

Qualification requirements:

• You owned the home for at least two of the five years before selling
• You used the home as your primary residence for at least two of those five years
• You haven't used the exclusion on another home in the past two years
• The two years don't have to be consecutive

Partial exclusions are available for certain circumstances even if you don't meet the full two-year requirement. Qualifying reasons include job relocation beyond 50 miles, health-related moves, or unforeseen circumstances like divorce or multiple births.

Investment properties don't qualify for the primary residence exclusion, making tax planning more critical. You'll face capital gains tax on real estate profits plus potential depreciation recapture tax on rental properties.

Example of depreciation recapture: Your rental property has a $100,000 total gain. You claimed $30,000 in depreciation over the years.

Some investors use a 1031 exchange to defer capital gains tax on real estate by reinvesting proceeds into a similar property. This like-kind exchange must follow strict IRS rules: you must identify replacement property within 45 days and close within 180 days, and the new property must be of equal or greater value.

States with no income tax (no state capital gains tax):

• Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, Wyoming
• New Hampshire (only taxes dividends and interest)

States with income tax typically tax long-term capital gains at the same rate as wages and other income. California has the highest top rate at 13.3%, meaning high earners could face a combined federal and state rate exceeding 33% on real estate gains.

Careful planning can significantly reduce capital gains tax on real estate. These strategies work within IRS rules to legally minimize your tax burden when selling property.

Timing strategies:

• Hold property for at least one year and one day to qualify for long-term rates
• Spread the sale across tax years using installment sales to stay in lower brackets
• Time the sale for a year when your other income is lower
• Harvest capital losses from other investments to offset gains

• Document all qualifying improvements with receipts and invoices
• Include often-overlooked purchase costs like surveys and inspection fees
• Track special assessments for improvements like sewer lines or sidewalks
• Keep records for the entire holding period

Opportunity Zones allow investors to defer capital gains by reinvesting proceeds into Qualified Opportunity Funds within 180 days. Gains can be permanently reduced by 10% if held five years, with all appreciation on the new investment potentially tax-free after ten years.

Charitable strategies can eliminate capital gains entirely. Donating appreciated property to charity gives you a deduction for the full fair market value without recognizing the gain.

Inherited property receives a step-up in basis to fair market value at the date of death. This means heirs can often sell inherited real estate immediately with little or no capital gain, regardless of how much the property appreciated during the deceased's lifetime.

Divorce property transfers between spouses or former spouses incident to divorce are generally tax-free. The recipient takes over the transferor's basis, meaning the capital gain is deferred until eventual sale.

Mixed-use property (part personal residence, part rental) requires allocation between qualified and non-qualified use for the Section 121 exclusion. Post-2008 rules reduce your exclusion based on periods of non-qualified use after the last date you lived there as a primary residence.

Do I pay capital gains tax if I sell my house and buy another?

Yes, you typically owe capital gains tax on real estate profits even if you buy another property immediately, unless you qualify for the primary residence exclusion ($250,000/$500,000). Simply purchasing another home doesn't defer the tax.

How long do you have to live in a house to avoid capital gains?

What happens if my capital gain exceeds the exclusion amount?

The amount exceeding the $250,000/$500,000 primary residence exclusion is taxed as a long-term capital gain at 0%, 15%, or 20% depending on your total taxable income for 2026. For example, if you're single with a $300,000 gain, you'd exclude $250,000 and pay capital gains tax on the remaining $50,000 based on your income bracket.

Can I deduct home improvements to reduce capital gains?

Yes, qualifying home improvements increase your cost basis and reduce your taxable capital gain. Improvements that add value, prolong the property's life, or adapt it to new uses qualify—such as room additions, new roofs, HVAC systems, or decks.
