When you sell a home or investment property, the IRS may tax the profit as a capital gain. How much you owe — or whether you owe anything at all — depends on how long you owned the property, how you used it, and your total taxable income. Most homeowners who sell a primary residence end up paying little or nothing in capital gains tax because of a generous federal exclusion, but investors and people selling second homes face a different picture.
For a broader view of how capital gains work before diving into real estate specifics, see the capital gains tax rates guide and the capital gains tax guide.
Primary Residence Exclusion
The primary residence exclusion under IRS Section 121 is the biggest tax break available to homeowners. It lets most sellers exclude a substantial chunk of their gain entirely, which is why the majority of people who sell a long-held home owe no federal capital gains tax at all.
If your home is your primary residence, you may exclude a significant gain from taxes:
| Filing Status | Maximum Exclusion |
|---|---|
| Single | $250,000 |
| Married Filing Jointly | $500,000 |
Requirements
The two-year ownership and use test does not have to be continuous. You simply need to have owned the home and lived in it as your primary residence for a combined total of at least 24 months out of the 60 months before the sale. The 60-month window gives sellers flexibility if they moved temporarily for work or family reasons.
| Requirement | Details |
|---|---|
| Ownership | Owned for 2+ of last 5 years |
| Residence | Lived there 2+ of last 5 years |
| Frequency | Haven’t used exclusion in past 2 years |
| Documentation | Keep records of purchase and improvements |
Example: Primary Residence
This example shows how improvement costs reduce your taxable gain by increasing your cost basis. Every dollar you can add to your basis is a dollar that is not taxed. See the cost basis guide for a full breakdown of what counts.
| Item | Amount |
|---|---|
| Original purchase price | $300,000 |
| Cost of improvements | $50,000 |
| Cost basis | $350,000 |
| Sale price | $550,000 |
| Selling costs | $33,000 |
| Net proceeds | $517,000 |
| Capital gain | $167,000 |
| Exclusion (married) | $500,000 |
| Taxable gain | $0 |
When You Owe Capital Gains Tax
There are three common situations where a home sale does trigger a tax bill: the gain exceeds the exclusion limit, you have not met the two-year residency test, or the property was never your primary residence. Investors who flip homes quickly should also note that gains on properties held less than one year are treated as short-term and taxed at ordinary income rates — not the lower long-term rates.
Exceeding the Exclusion
Married couple, gained $600,000:
| Item | Amount |
|---|---|
| Total gain | $600,000 |
| Exclusion | -$500,000 |
| Taxable gain | $100,000 |
| Tax (at 15% rate) | $15,000 |
Not Meeting Requirements
| Situation | Tax Treatment |
|---|---|
| Lived there < 2 years | Partial exclusion possible* |
| Investment property | Full gain taxable |
| Rental property | Full gain taxable |
| Flipped (< 1 year) | Short-term rates |
*Partial exclusion if moved for work, health, or unforeseen circumstances
Capital Gains Tax Rates
The rate that applies to your taxable real estate gain depends on how long you held the property and your total income for the year. Long-term rates are meaningfully lower than short-term rates, which is why holding period planning matters even for investment properties. The full bracket breakdown by filing status is on the capital gains tax rates page.
Long-Term (Held Over 1 Year)
| 2026 Taxable Income (Single) | Rate |
|---|---|
| $0 - $48,350 | 0% |
| $48,350 - $533,400 | 15% |
| Over $533,400 | 20% |
| 2026 Taxable Income (Married) | Rate |
|---|---|
| $0 - $96,700 | 0% |
| $96,700 - $600,050 | 15% |
| Over $600,050 | 20% |
Short-Term (Held Under 1 Year)
Taxed as ordinary income (10%-37% depending on bracket)
Net Investment Income Tax
High earners may also owe 3.8% NIIT on investment income above the thresholds below. This surtax stacks on top of the regular long-term rate, meaning a high-income investor can face an effective rate of up to 23.8% on a long-term gain. See the net investment income tax guide for more detail.
- Single: Income over $200,000
- Married: Income over $250,000
Calculating Capital Gains
Your taxable gain is not simply the sale price minus what you originally paid. You can add improvement costs, certain closing costs, and selling expenses to your cost basis, which reduces the gain. Getting this right can mean the difference between owing tax and owing nothing. Use our capital gains calculator to run the numbers for your situation.
Step-by-Step
Sale Price
- Selling Costs (commissions, fees)
= Net Proceeds
Original Purchase Price
+ Closing Costs (when bought)
+ Capital Improvements
+ Selling Costs (when sold)
= Adjusted Cost Basis
Net Proceeds - Adjusted Cost Basis = Capital Gain
What Counts as Cost Basis
| Included | Not Included |
|---|---|
| Purchase price | Furniture |
| Closing costs (buy) | Repairs/maintenance |
| Major improvements | Insurance premiums |
| Assessments | Property taxes |
| Legal fees | Utility costs |
Common Improvements to Track
| Improvement | Adds to Basis? |
|---|---|
| Kitchen remodel | Yes |
| Room addition | Yes |
| New roof | Yes |
| New HVAC | Yes |
| Landscaping | Yes (permanent) |
| Painting | Usually no (maintenance) |
| Appliances | Usually no |
Investment Property Tax Rules
If you rent out a property or use it primarily as an investment, the rules are stricter. There is no Section 121 exclusion available, and you also have to contend with depreciation recapture — a separate tax on the deductions you took while you owned the property.
Investment properties don’t qualify for the primary residence exclusion:
Example: Rental Property
| Item | Amount |
|---|---|
| Purchase price | $200,000 |
| Improvements | $30,000 |
| Depreciation claimed | -$50,000 |
| Adjusted basis | $180,000 |
| Sale price | $350,000 |
| Selling costs | -$21,000 |
| Net proceeds | $329,000 |
| Capital gain | $149,000 |
Depreciation Recapture
Depreciation recapture is one of the most overlooked costs of selling a rental property. When you take depreciation deductions during ownership, the IRS treats those deductions as having reduced your cost basis. At sale, it “recaptures” those amounts and taxes them at a flat 25% rate, separate from the standard capital gains rate on the rest of your gain. See the depreciation recapture guide for a deeper explanation and planning strategies.
| Type | Tax Rate |
|---|---|
| Depreciation recapture | 25% |
| Remaining gain (long-term) | 0/15/20% |
Using example above:
| Component | Amount | Tax Rate | Tax |
|---|---|---|---|
| Depreciation recapture | $50,000 | 25% | $12,500 |
| Remaining gain | $99,000 | 15% | $14,850 |
| Total tax | $27,350 |
Strategies to Reduce Capital Gains
Real estate investors have more tools available than most taxpayers to reduce or defer a capital gains bill. These strategies range from the widely used 1031 exchange to the less-known opportunity zone deferral. The right approach depends on whether you want to defer the tax, reduce it now, or eliminate it entirely with a primary residence conversion.
1031 Exchange
Defer taxes by exchanging for another investment property:
| Requirement | Details |
|---|---|
| Property type | Like-kind (investment for investment) |
| Timeline | 45 days to identify, 180 days to close |
| Value | Must be equal or greater value |
| Primary residence | Not eligible |
Installment Sale
Spread the gain over multiple years:
- Receive payments over time
- Report gains as received
- May lower annual tax bracket
Opportunity Zones
Invest gains in designated opportunity zones — see the opportunity zones guide for eligibility rules and current program status:
- Defer original gain until 2026
- Reduce gain by 10% if held 5+ years
- Exclude gains on new investment if held 10+ years
Convert to Primary Residence
- Move into rental for 2+ years before selling
- Qualify for primary residence exclusion
- Note: Rules limit exclusion for properties previously rented
State Capital Gains Taxes
Federal taxes are only part of the picture. Most states also tax capital gains, and the rates can be significant. A few states have no capital gains tax at all, which makes them popular destinations for retirees planning large property sales.
| State | Rate |
|---|---|
| No state capital gains tax | AK, FL, NV, NH*, SD, TN*, TX, WA*, WY |
| California | Up to 13.3% |
| New York | Up to 8.82% |
| New Jersey | Up to 10.75% |
| Most states | Taxed as income |
*Some states tax only dividends/interest, not all capital gains
Record-Keeping Checklist
Good records reduce your tax bill on a home sale because every documented improvement cost adds to your basis and reduces the taxable gain. Keep everything from both the purchase and the sale, and hold onto records longer than you think you need to. The IRS generally has three years to audit a return, but basis errors on property can be challenged much later if the records are missing.
Keep these documents for tax purposes:
| Document | Purpose |
|---|---|
| Settlement statement (buy) | Proves cost basis |
| Improvement receipts | Adds to basis |
| Settlement statement (sell) | Proves sale price |
| Mortgage statements | Documents costs |
| Depreciation records | For rentals |
| 1099-S form | Reports sale to IRS |
Keep records for at least 3 years after filing (7 years recommended)
