Understanding Capital Gains on Your Home Sale - 12/31/2025

Selling your home can be a significant financial event and it's important to understand how capital gains taxes may apply. Fortunately, U.S. tax law offers generous exclusions for homeowners under certain conditions, and with proper recordkeeping, many can reduce or eliminate their tax burden altogether.

Here's what every homeowner should know about capital gains, exclusions, and the importance of documenting improvements.

What Are Capital Gains?

Capital gain is the profit you make from selling your home. It's calculated as the difference between your adjusted cost basis and the sale price (minus allowable selling costs, such as real estate commissions).

Sale Price ... (Purchase Price + Capital Improvements + Selling Costs) = Capital Gain

Capital Gains Exclusion for Your Primary Residence

Under IRS rules, if the home you're selling is your primary residence, you may be eligible to exclude a portion of the capital gain from taxation.  If the home you're selling is your primary residence, you may be able to exclude up to $250,000 in capital gains if you're single, or up to $500,000 if you're married and file jointly.

To qualify, you must have owned and lived in the home for at least two of the five years before the sale, and you must not have used this exclusion on another property in the past two years. This exclusion can make a significant difference in the net proceeds from your sale.

Example: A married couple sells their home for $800,000. They bought it for $400,000 and made $50,000 in qualifying improvements. After deducting $30,000 in selling expenses, their gain is $320,000. Since that's under the $500,000 exclusion, they owe no capital gains tax.

Why Tracking Home Improvements Matters

Your cost basis isn't just the purchase price; it includes the cost of capital improvements made to the home. These improvements can reduce your taxable gain by increasing your basis.

Capital improvements are upgrades that either add value to the home, prolong its useful life, or adapt it to new uses.  It is only necessary to meet one of these requirements.

Examples of improvements that increase your basis:

  • Adding a room or garage
  • Installing a new roof or HVAC system
  • Remodeling a kitchen or bathroom
  • Replacing windows or flooring
  • Building a deck or finishing a basement

Routine maintenance and repairs, such as painting, fixing a leaky faucet, or patching a roof, do not qualify. They may be necessary, but they don't add to your basis.

Pro Tip: Keep a Home File

Keeping a folder or digital record that includes purchase documents, receipts for improvements, contractor invoices, permits and plans, and records of major appliance installations can be valuable for proof in case of an audit.  Photos before and after can also be helpful.

This documentation can make a significant difference when it's time to sell and report your capital gain.  For more information, contact your tax professional and download IRS Publication 530.

In Summary

  • Capital gains are based on your sale price minus your adjusted cost basis.
  • Homeowners may exclude up to $250,000 (single) or $500,000 (married) in gains on their primary residence.
  • Documenting improvements is essential to reduce your potential tax bill.
  • Only capital improvements, not maintenance, add to your cost basis.

By understanding these rules and keeping good records, you can make the most of the tax advantages of homeownership and retain more of your equity when you sell.  Download our Homeowners Tax Guide.
