Understanding Capital Gains Tax on Real Estate
Before looking at when the tax is due, it’s important to understand what capital gains tax covers.
Capital gains tax applies to the profit you make from selling a property at a higher price than your adjusted basis. Your basis typically includes:
- The original purchase price
- Closing costs (in some cases)
- Capital improvements (such as renovations, additions, or major upgrades)
Example:
- Purchase price: $300,000
- Renovations: $50,000
- Adjusted basis: $350,000
- Sale price: $600,000
- Capital gain: $250,000
This $250,000 is what may be subject to capital gains tax, depending on your situation.
When Do You Actually Pay Capital Gains Tax on Real Estate?
The simple answer:
👉 You usually pay capital gains tax when you file your federal tax return for the year in which the sale takes place.
If you sell a property in July 2025, the tax is generally due when filing your 2025 tax return — typically by April 15, 2026.
However, certain situations can change when payments are due. For example:
- If you owe a large amount, you may need to make estimated tax payments during the same year.
- If you’re doing a 1031 exchange, payment may be deferred entirely.
- Some states withhold taxes at closing for nonresidents.
- Seller-financed deals may spread the tax across several years.
The timing depends on the property type and how the transaction is structured.
Selling Your Primary Residence
For most homeowners, selling a primary residence comes with the home sale exclusion, which can eliminate or significantly reduce capital gains tax.
Home Sale Exclusion Rule
You may exclude up to:
- $250,000 in gains if single
- $500,000 if married filing jointly
To qualify, you must meet both:
- Ownership Test: Owned the home for at least 2 of the last 5 years.
- Use Test: Lived in the home as your primary residence for at least 2 of the last 5 years.
If your profit is below the exclusion amount, you may owe no capital gains tax at all.
When Is the Tax Paid?
If your gain exceeds the exclusion, you’ll owe capital gains tax on the portion above the limit. This amount is usually paid when filing your tax return the year after the sale.
Example:
- Married couple sells a home for $900,000.
- Adjusted basis: $300,000.
- Gain: $600,000.
- Exclusion: $500,000.
- Taxable gain: $100,000.
- Taxes due: When filing the tax return for that year.
Selling Investment or Rental Property
When you sell investment or rental property, the home sale exclusion does not apply. The entire gain is generally taxable, and the timing of payment depends on the type of gain.
Short-Term vs. Long-Term Gains
- Short-term gain: Property held 1 year or less → taxed as ordinary income.
- Long-term gain: Property held more than 1 year → taxed at long-term capital gains rates (0%, 15%, or 20%, depending on income).
In addition to federal tax, you may owe:
- Depreciation recapture tax (usually 25%) on previously deducted depreciation.
- State capital gains taxes, depending on where the property is located.
When Is the Tax Paid?
- Usually when you file your tax return for the year of sale.
- But if your profit is large, you may need to make quarterly estimated payments during the year to avoid penalties.
Using a 1031 Exchange to Defer Payment
One powerful way to delay capital gains tax on investment property is through a 1031 exchange. This allows you to sell a property and reinvest the proceeds into another like-kind property, deferring taxes.
Key Timing Rules
- Identify a replacement property within 45 days of the sale.
- Complete the purchase within 180 days.
- Follow strict IRS procedures for the exchange to qualify.
If done correctly, you don’t pay capital gains tax in the year of sale. Instead, the tax is deferred until the replacement property is eventually sold without another exchange.
When Is the Tax Paid?
At the time of a future sale, unless you continue to roll over the gains into new properties.
Inherited Real Estate
When you inherit real estate, the tax rules are different. You don’t pay capital gains tax at the time of inheritance. Instead, the property’s basis is stepped up to its fair market value on the date of the original owner’s death.
Capital gains tax applies only when you sell the inherited property, and only on the increase between the stepped-up value and the sale price.
When Is the Tax Paid?
In the tax year following the sale of the inherited property.
Seller Financing and Installment Sales
Some sellers choose to finance the buyer themselves, receiving the sale price in installments over several years. In these cases, the IRS often allows the use of the installment method.
This method lets you spread out the capital gains tax payments proportionally over each year you receive payments.
When Is the Tax Paid?
Each year when you receive payments, rather than all at once in the year of sale.
Key Capital Gains Tax Deadlines for Real Estate
| Event | Tax Action | Typical Deadline |
|---|---|---|
| Real estate sale closes | Gain realized | Closing date |
| Tax payment (no deferral) | Pay capital gains via tax return | April of following year |
| Estimated taxes (if required) | Quarterly payments to avoid penalties | April, June, Sept, Jan |
| 1031 exchange identification | Replacement property identified | Within 45 days of sale |
| 1031 exchange closing | New property purchase completed | Within 180 days of sale |
| Installment sale payments | Taxes paid proportionally as payments are received | Each year after the sale |
Recent 2025 Updates Affecting Timing
Several factors in 2025 are shaping when sellers pay capital gains tax on real estate:
- Rising property values mean more sellers are exceeding exclusion limits for the first time.
- Increased IRS enforcement of underreported property gains and 1031 exchange errors.
- Tighter timelines on estimated tax payments for high-income sellers.
- More people using installment sales and trust structures to manage tax timing strategically.
These shifts make understanding your deadlines and options more critical than ever.
Strategies to Manage or Delay Payment
Knowing when you pay is key, but strategic timing can help minimize or defer taxes:
- Sell in a lower-income year to qualify for a lower capital gains rate.
- Use a 1031 exchange to defer payment on investment properties.
- Leverage the home sale exclusion by meeting ownership and use tests.
- Invest in improvements before selling to raise your basis.
- Use installment sales to spread taxes across multiple years.
Proactive planning often makes a meaningful difference in how much you ultimately pay.
