When Do You Pay Capital Gains Tax on Real Estate?

You pay capital gains tax on real estate for the tax year in which the sale closes, and the money is due when you file that year’s federal return, typically by April 15 of the following year. If the gain is large, the IRS expects a quarterly estimated payment during the year rather than a lump sum at filing. Many homeowners selling a primary residence owe nothing at all, because a federal exclusion shelters up to $250,000 of profit for single filers and $500,000 for married couples filing jointly.

The Taxable Event Is the Closing

The date the title legally transfers to the buyer is the date that fixes your tax year. Close on December 28, 2026, and the gain belongs on your 2026 return, even though you won’t file until spring 2027. Close on January 3, 2027, and the same sale lands a full year later on the calendar.

Nothing is withheld at the closing table for federal capital gains tax. What does happen is paperwork: the closing agent or settlement attorney files Form 1099-S with the IRS reporting the gross proceeds, and you get a copy. Even if the entire gain is excluded under the primary-residence rules, you should report the sale on your return if a 1099-S was issued, because the IRS already has the record.¹

When You Actually Hand Over the Money

The tax is due by the annual filing deadline for the year of the sale, usually April 15 of the following year. Waiting until that date to settle a large capital gains bill, though, often triggers an underpayment penalty. The IRS treats income tax as a pay-as-you-go obligation, and a six-figure gain creates a wide gap between what you’ve already paid through withholding and what you’ll owe.

You avoid the penalty if your total payments for the year (withholding plus estimated payments) reach at least 90% of the current year’s tax or at least 100% of the prior year’s tax. If your adjusted gross income exceeded $150,000 in the prior year ($75,000 if married filing separately), that prior-year safe harbor rises to 110%.² For most sellers of appreciated property, hitting one of those safe harbors means sending an estimated payment in the quarter the sale closes.

Estimated Payment Deadlines for 2026

Quarterly estimated tax payments for the 2026 tax year are due on:³

First quarter: April 15, 2026
Second quarter: June 15, 2026
Third quarter: September 15, 2026
Fourth quarter: January 15, 2027

A sale that closes in March belongs with the first-quarter payment. A sale that closes in November can be covered by the January payment. The goal is to get the money in during the quarter the gain is realized, so the penalty doesn’t accrue in the intervening months.

Figuring the Gain You’ll Report

Your taxable gain is the net sale price minus your adjusted basis. Every legitimate addition to basis, and every selling cost subtracted from the sale price, reduces what you owe, so the records you kept during ownership matter here more than almost anywhere else in your taxes.

Net Sale Price

Start with the contract price and subtract your selling expenses: real estate commissions, advertising, legal fees, transfer taxes you paid as the seller, and any loan charges you covered that the buyer would normally pay.⁴ The result is sometimes called the amount realized.

Adjusted Basis

Basis starts with what you originally paid, including settlement costs at purchase like title insurance, legal fees, and recording fees. From there it moves in two directions over the years you own the property. Capital improvements that add value, extend useful life, or adapt the property to a new use raise your basis: a new roof, an added bathroom, a full kitchen renovation, a new HVAC system. Depreciation you claimed (or were required to claim) on rental or business property lowers your basis. Depreciation is mandatory for rental real estate, so the IRS treats it as claimed whether you actually deducted it or not.

Routine maintenance such as fixing a leaky faucet or repainting does not increase basis. For a rental, those costs are deductible as operating expenses in the year they occur, but they don’t shrink your eventual capital gain. The line between an improvement and a repair is one of the most common audit triggers for real estate, and the IRS draws it at whether the work materially adds value or merely keeps the property functional.

Short-Term vs. Long-Term Rates

How long you owned the property decides which rate applies. The holding period starts the day after you acquired the property and ends on the closing date of the sale.⁵

Hold for one year or less and the gain is short-term, taxed at your ordinary income rates, which run from 10% to 37% in 2026.⁵ Short-term real estate gains are relatively uncommon outside of flipping, but the bite is steep when they happen.

Hold for more than one year and the gain is long-term, with lower brackets. For 2026:

0%: taxable income up to $49,450 (single), $98,900 (married filing jointly), or $66,200 (head of household).
15%: taxable income above that up to $545,500 (single), $613,700 (married filing jointly), or $579,600 (head of household).
20%: taxable income above the 15% ceiling.

These thresholds are based on your total taxable income for the year, not just the gain from the sale.⁶ Most sellers of investment real estate land in the 15% bracket.

The Primary-Residence Exclusion

The Section 121 exclusion is the reason most home sellers owe no capital gains tax. A single filer can exclude up to $250,000 of gain on a primary residence; a married couple filing jointly can exclude up to $500,000.⁷ For the married threshold, both spouses must meet the use requirement and at least one must meet the ownership requirement.

Ownership and Use

To claim the full exclusion, within the five-year window ending on the sale date you must have owned the home for at least two years and used it as your main residence for at least two years. The two years don’t need to be consecutive, and the ownership and use periods don’t have to overlap.⁸ You can only use the exclusion once every two years, so if you claimed it on a previous sale, you need to wait at least 24 months before claiming it again.

Only gain above the limit is taxed. A married couple with a $600,000 gain excludes $500,000 and pays long-term capital gains tax on the remaining $100,000.⁷

Partial Exclusion for an Early Sale

If you sell before meeting the two-year requirement, a prorated exclusion is still possible when the sale was primarily due to a qualifying work relocation, a health condition, or certain unforeseeable events. For a work-related move, the new job location generally needs to be at least 50 miles farther from the home than the old one. Health-related moves include selling to obtain or provide care for a family member’s illness or injury. Unforeseeable events include destruction of the home, divorce, or becoming unable to pay basic living expenses after a change in employment.⁴

The partial amount is the full $250,000 or $500,000 cap multiplied by the fraction of the two-year requirement you actually satisfied. A single filer who lived in the home for 15 months before a qualifying job transfer would have a partial exclusion of 15/24 of $250,000, or $156,250.

Extra Taxes on Investment Property

Sellers of rental or business property face two layers of tax that don’t apply to a personal residence.

Depreciation Recapture

Any depreciation you claimed during ownership is recaptured at sale. The portion of your gain equal to total depreciation claimed is taxed at a maximum rate of 25%, regardless of which long-term bracket you’d otherwise sit in.⁹

Say you bought a rental, claimed $80,000 in depreciation over the years, and now sell at a $200,000 long-term gain. The first $80,000 is taxed at up to 25% as recapture. The remaining $120,000 is taxed at your regular long-term rate of 0%, 15%, or 20%. Sellers who forget recapture when estimating their bill often come up short at filing time.

The 3.8% Net Investment Income Tax

Higher-income sellers of investment real estate also owe the Net Investment Income Tax, a 3.8% surtax on the lesser of net investment income or the amount your modified adjusted gross income exceeds these thresholds:¹⁰

$250,000 for married filing jointly or qualifying surviving spouse
$200,000 for single or head of household
$125,000 for married filing separately

These thresholds are not indexed for inflation, so they catch more taxpayers each year. Capital gains from investment real estate, including second homes, count as net investment income.¹¹ A seller in the 20% long-term bracket who also owes the NIIT faces an effective federal rate of 23.8% on the gain, plus up to 25% on any recapture portion.

State Tax Is Separate

Federal tax is not the only bill. Most states tax capital gains at their ordinary income rates, and those rates vary widely. A handful of states impose no income tax at all, while others have top rates above 10%. For a high-income seller in a high-tax state, combined federal and state tax on a real estate gain can easily exceed 30%. Check your state’s current rules before estimating your after-tax proceeds, because the state portion is one of the most frequently overlooked costs in a sale.

How You Report the Sale

Real estate gains are reported on Form 8949, where you list the purchase date, sale date, sale price, and adjusted basis. Totals flow to Schedule D (Form 1040), which calculates your net gain or loss across all capital transactions for the year.¹² If you’re claiming the Section 121 exclusion on a primary residence, you still use Form 8949 when a Form 1099-S was issued.¹³ For a large gain, running the numbers with a tax professional before the quarterly deadline that follows your closing is usually worth the cost, because the right estimated payment protects you from a penalty that compounds the longer the shortfall sits.
