Do I pay capital gains tax when I sell my home?

Most homeowners pay no capital gains tax on their home sale thanks to the Section 121 exclusion. If you owned and lived in the home as your primary residence for at least 2 of the 5 years before the sale, you can exclude up to $250,000 in profit (single filers) or $500,000 (married filing jointly) from capital gains tax. Profit is your sale price minus your cost basis (original purchase price plus improvements). If your profit exceeds these limits, only the amount above the exclusion is taxable.

What is the Section 121 home sale exclusion?

Section 121 of the IRS tax code allows homeowners who meet the ownership and use tests to exclude up to $250,000 ($500,000 married) of capital gains from the sale of their primary residence. The ownership test: you owned the home for at least 2 years during the 5-year period ending on the sale date. The use test: you used the home as your primary residence for at least 2 years during the same 5-year period. The 2 years do not need to be consecutive.

What if I sell my home before living there for 2 years?

If you sell before meeting the 2-year requirement, you may qualify for a partial exclusion if the sale was due to a job change, health reasons, or unforeseen circumstances. The partial exclusion is proportional: if you lived there 1 year (50% of the 2-year requirement), you can exclude 50% of the normal exclusion ($125,000 single / $250,000 married). Job relocation must be at least 50 miles farther from your home than your old job. Consult IRS Publication 523 for the full list of qualifying circumstances.

What capital gains tax rate applies to home sale profit above the exclusion?

Home sale profit above the exclusion is taxed as long-term capital gains (since you owned the home for at least a year). Long-term capital gains tax rates for 2026: 0% (taxable income up to $47,025 single / $94,050 married), 15% ($47,026–$518,900 single / $94,051–$583,750 married), 20% (above $518,900 single / $583,750 married). High-income filers may also owe the 3.8% Net Investment Income Tax (NIIT) on the taxable gain.

How does the cost basis work for home sales?

Your cost basis is what you paid for the home, plus qualifying improvements and expenses. Cost basis = original purchase price + closing costs paid at purchase + cost of permanent improvements (additions, new roof, kitchen remodel, HVAC) + selling costs (agent commissions, closing costs). Keep records of all home improvements — these reduce your taxable gain. For example: bought for $300,000, added $50,000 kitchen addition, sold for $600,000. Basis = $350,000. Profit = $250,000. Single filer exclusion = $250,000. Tax owed = $0.

Capital Gains Tax on Home Sale 2026 — How to Exclude Up to $500,000

When you sell your primary residence in 2026, you can exclude up to $250,000 in profit from capital gains tax if you’re single, or $500,000 if you’re married filing jointly — as long as you owned and lived in the home for at least 2 of the past 5 years. Most homeowners pay no capital gains tax on their home sale. Profit above the exclusion limit is taxed at long-term capital gains rates (0%, 15%, or 20%).

Quick answer: You owned your home for 2+ years and lived in it as your primary residence? Profit up to $250,000 (single) or $500,000 (married) is tax-free. Keep records of all home improvements — they increase your cost basis and reduce taxable profit. Only profits exceeding the exclusion are taxed.

The $250,000 / $500,000 Home Sale Exclusion

Filing Status	Maximum Tax-Free Profit
Single	$250,000
Married Filing Jointly	$500,000
Married Filing Separately	$250,000 each
Head of Household	$250,000

Requirements (must meet both):

Ownership test: You owned the home for at least 24 months (730 days) during the 5-year period ending on the sale date
Use test: You used the home as your primary residence for at least 24 months during the same 5-year period
Frequency test: You have not used this exclusion on another home sale in the past 2 years

The 24 months do not need to be consecutive — you just need to total 24 months within the 5-year lookback window.

How to Calculate Your Taxable Gain (or Confirm You Owe Nothing)

Step 1: Determine your adjusted cost basis

Original purchase price
+ Closing costs at purchase (title fees, legal fees, recording fees)
+ Capital improvements (renovations, additions, permanent upgrades)
+ Selling costs (agent commission, closing costs, legal fees at sale)
= Adjusted Cost Basis

Step 2: Calculate gross profit

Sale price − Adjusted Cost Basis = Gross Profit

Step 3: Apply the exclusion

Gross Profit − $250,000 (single) or $500,000 (married) = Taxable Gain

If Taxable Gain is ≤ $0, you owe no capital gains tax.

Worked Example 1 — No tax owed:

Bought for: $350,000
Improvements: $40,000 (new kitchen, bathroom addition)
Agent commission: $24,000 (4%)
Sale price: $620,000
Adjusted basis: $350,000 + $40,000 + $24,000 = $414,000
Gross profit: $620,000 − $414,000 = $206,000
Married couple exclusion: $500,000
Taxable gain: $0 (well under exclusion)

Worked Example 2 — Tax owed (high-profit market):

Bought for: $400,000 in 2010
Improvements: $80,000
Selling costs: $30,000
Sale price: $1,200,000
Adjusted basis: $510,000
Gross profit: $690,000
Married couple exclusion: $500,000
Taxable gain: $190,000
Tax at 15% long-term capital gains rate: $28,500

What Counts as a Capital Improvement (Increases Your Basis)

Qualifies as Improvement	Does NOT Qualify
Room addition	Routine maintenance (painting, fixing a leak)
Kitchen or bathroom remodel	Repairs that restore original condition
New roof	Landscaping (in most cases)
Heating/cooling system replacement	Cleaning services
Deck or patio addition	Appliances (usually)
New windows or doors	Interest on home equity loans
Built-in appliances (dishwasher, oven)
Insulation
Solar panels

Record keeping matters: Save receipts, contractor invoices, and permits for all home improvements — you may need them years later when you sell.

Capital Gains Tax Rates for Home Sale Profit Above Exclusion (2026)

Filing Status	0% Rate	15% Rate	20% Rate
Single	Up to $47,025 taxable income	$47,026–$518,900	Above $518,900
Married Filing Jointly	Up to $94,050	$94,051–$583,750	Above $583,750
Head of Household	Up to $63,000	$63,001–$551,350	Above $551,350

The taxable gain is added to your other taxable income to determine your bracket.

Net Investment Income Tax (NIIT): If your modified AGI exceeds $200,000 (single) or $250,000 (married), an additional 3.8% NIIT applies to the lesser of your net investment income or the amount your MAGI exceeds the threshold. This applies to the taxable home sale gain.

Partial Exclusion for Sales Before 2 Years

If you must sell before meeting the 2-year requirement, you may get a partial exclusion for qualifying reasons:

Qualifying Reason	Partial Exclusion
Job relocation (new job ≥50 miles farther from home)	Proportional (days owned ÷ 730 × full exclusion)
Health reasons (doctor-recommended move)	Proportional
Unforeseen circumstances (job loss, divorce, natural disaster, death)	Proportional

Example: Lived there 12 months (50% of required 24). Single filer. Partial exclusion = 50% × $250,000 = $125,000.

Special Situations

Home office deduction users: If you claimed depreciation deductions on a home office portion of your home, that portion’s depreciation is “recaptured” and taxed at up to 25% (not capital gains rates) when you sell.

Inherited homes: Inherited property receives a stepped-up basis to fair market value at date of death. Capital gains are calculated from that new basis — eliminating all appreciation during the prior owner’s lifetime.

Rental property: If you converted a rental property to your primary residence, you can still use the Section 121 exclusion for the qualifying period you lived in it, but you cannot exclude gain attributable to periods of nonqualified use (rental periods after May 6, 1997).

Divorced homeowners: Divorced individuals each get the $250,000 single exclusion. If a spouse receives the house in a divorce and sells it, they can count the time the other spouse owned it toward the ownership test (use test must still be met).

Form and Reporting Requirements

If you qualify for the full exclusion and your gain is entirely excluded: you do not need to report the sale on your tax return (generally)
If any gain is taxable: report on Schedule D and Form 8949
If you receive a Form 1099-S (proceeds from real estate transactions): report the sale even if fully excluded
Ask your closing attorney or title company whether they will issue a Form 1099-S
