How much profit can you make selling a house without paying taxes?

Under the Section 121 exclusion, you can exclude up to $250,000 of capital gain (Single) or $500,000 (Married Filing Jointly) from the sale of your primary residence. To qualify, you must have owned and lived in the home for at least 2 of the last 5 years.

How do I calculate capital gains on a home sale?

Your gain is the sale price minus your adjusted basis. Your basis starts as your purchase price, plus closing costs, then is increased by capital improvements (renovations, additions) and decreased by depreciation taken. The resulting gain minus the Section 121 exclusion (if eligible) is your taxable gain.

Do I have to report the sale of my home on my tax return?

If you meet the Section 121 exclusion requirements and your gain is less than the exclusion amount, you generally do not need to report the sale. However, if you receive a Form 1099-S, or if any portion of the gain is taxable, you must report it on Schedule D.

What if I used my home as a rental property?

Periods of rental use may reduce your exclusion eligibility and trigger depreciation recapture. Under the 'nonqualified use' rules, gain allocated to periods after 2008 when the property was not your primary residence may not be excludable. Any depreciation taken during the rental period is recaptured at a 25% rate.

Selling a House: Capital Gains Exclusion and Tax Rules

Understand the Section 121 home sale exclusion ($250k single / $500k MFJ), how to calculate your gain, and strategies to minimize taxes when selling your home.

Last updated on March 22, 2026

Selling your home is likely the largest financial transaction of your life — and for most homeowners, the tax bill is zero thanks to the Section 121 exclusion. But the rules have nuances that matter, especially if you have had significant appreciation, rental use, or have not lived in the home for the full period. Understanding capital gains tax rates and how capital gains differ from ordinary income is essential before listing your property.

Key Takeaways

Exclude up to $250,000 (single) or $500,000 (MFJ) of gain from your primary residence.
Ownership + use test: Own and live in the home for at least 2 of the last 5 years.
Capital improvements increase your basis and reduce your taxable gain.
Depreciation recapture applies at 25% if the home was used as a rental.
You can use the exclusion once every 2 years.

The Section 121 Exclusion

The most powerful tax break in real estate. If you sell your primary residence, you can exclude:

$250,000 of gain (Single, Head of Household, Married Filing Separately)
$500,000 of gain (Married Filing Jointly — both spouses must meet the use test; only one must meet the ownership test)

Qualification Requirements

Ownership test: You owned the home for at least 2 of the 5 years before the sale.
Use test: You lived in the home as your primary residence for at least 2 of the 5 years before the sale. The 2 years do not need to be consecutive.
Frequency test: You have not used the exclusion in the past 2 years.

Partial exclusion: If you do not meet the full 2-year requirement due to a job change, health condition, or unforeseen circumstances, you may qualify for a partial exclusion (prorated based on time lived there).

Calculating Your Gain

Gain = Sale Price − Selling Expenses − Adjusted Basis

Adjusted Basis

Your basis starts as the purchase price and is adjusted:

Increases to basis (reduces gain):

Closing costs at purchase (title insurance, attorney fees, recording fees)
Capital improvements (new roof, kitchen renovation, room addition, new HVAC)
Special assessments for local improvements

Decreases to basis (increases gain):

Depreciation taken if the home was used for business or rental
Casualty loss deductions claimed
Certain energy credits received

Not added to basis: Routine maintenance, repairs, and insurance costs.

Example

Item	Amount
Sale price	$800,000
Selling expenses (agent, closing)	−$48,000
Net sale price	$752,000
Original purchase price	$350,000
Closing costs at purchase	+$8,000
Capital improvements (kitchen, roof)	+$45,000
Adjusted basis	$403,000
Gain	$349,000
Section 121 exclusion (MFJ)	−$349,000
Taxable gain	$0

When the Exclusion Is Not Enough

If your gain exceeds the exclusion amount, the excess is taxed as a capital gain:

Long-term capital gains rate (0%, 15%, or 20%) if you owned the home for more than 1 year.
Plus the 3.8% Net Investment Income Tax (NIIT) if your income exceeds $200,000 (single) / $250,000 (MFJ).

Example: A single filer sells for a $400,000 gain. The $250,000 exclusion covers most of it. The remaining $150,000 is taxed at 15% ($22,500) plus potentially 3.8% NIIT ($5,700) for a high earner. To understand how this fits into your overall tax bracket, see our bracket guide.

Special Situations

Home Used as Rental or Business

If you converted your primary residence to a rental property and later sold it:

Depreciation recapture: Any depreciation you claimed (or were allowed to claim) is taxed at a flat 25% rate, even if you qualify for the Section 121 exclusion on the rest. If you claimed depreciation for a home office or rental portion (for example, using MACRS depreciation), all of that depreciation is recaptured at sale.
Nonqualified use rule: Gain allocated to periods of non-primary-residence use after 2008 may not be excludable. The IRS uses a formula: (nonqualified use days / total ownership days) × gain = non-excludable gain. For more on rental property taxation, see our rental property tax guide.

Divorce and Home Sales

For a full overview of how divorce affects filing status, property transfers, and alimony, see our divorce and taxes guide.

If one spouse keeps the home and later sells, they can still use their individual $250,000 exclusion.
If the home is transferred as part of the divorce settlement, the receiving spouse inherits the transferring spouse’s basis and holding period.
Joint filers during the year of sale can use the $500,000 exclusion.

Inherited Homes

Inherited property receives a stepped-up basis to the fair market value at the date of death. If you inherit a home worth $500,000, your basis is $500,000 — even if the decedent paid $100,000 decades ago. This eliminates gain on the pre-inheritance appreciation. For a broader look at inheritance rules, see our inheritance tax vs. estate tax guide. However, the Section 121 exclusion only applies if you live in the home as your primary residence for at least 2 of 5 years before selling. For the complete rules on ownership tests, partial exclusions, and related strategies, see our home sale capital gains exclusion guide.

Strategies to Minimize Home Sale Taxes

Track every capital improvement. Keep receipts for renovations, additions, landscaping, and system replacements. Every dollar of improvement increases your basis.
Time the sale. Ensure you meet the 2-year ownership and use test before selling.
Consider a 1031 exchange if the property is an investment (not primary residence). This defers gain into a replacement property.
Installment sale. Spread gain over multiple years to manage bracket impact.
Harvest losses. Offset any taxable home sale gain with tax loss harvesting from your investment portfolio.
Invest in a Qualified Opportunity Zone. If you have taxable gain, reinvesting in a Qualified Opportunity Zone fund can defer and potentially reduce the gain.
Coordinate with your overall tax plan. Use the home sale year to evaluate Roth conversions, charitable bunching, and other strategies that interact with your capital gains. A year-end tax checklist can help you time the sale for maximum benefit.
