Most home improvements cannot be deducted from your taxes in the year you make them

The IRS does not treat home improvements the same way it treats business expenses or medical costs. When you replace your roof, add a deck, or upgrade your kitchen, you generally cannot subtract that cost from your income on your tax return. The money you spend on improvements stays off your tax forms.

The one exception is if you use part of your home for business—a home office, rental unit, or studio—and the improvement benefits that space. Even then, the rules are narrow and the deduction is limited. For most homeowners, home improvements affect taxes only when you sell the house, and even then, not in the way many people expect.

Key Takeaways

  • Home improvements made to your primary residence cannot be deducted as a tax expense in the year you pay for them.
  • If you use part of your home for business, improvements to that space may be deductible, but you need to track the business percentage and follow IRS rules for depreciation.
  • Home improvements can lower your taxable gain when you sell your house, but only if you keep receipts and records proving what you spent and when.
  • Repairs and maintenance—fixing a leaky roof or patching drywall—are different from improvements and have their own tax rules.
  • Energy-efficient improvements like solar panels or heat pumps may may have access to for a federal tax credit, which is different from a deduction.

The difference between improvements and repairs

The IRS distinguishes between a repair and an improvement. A repair fixes something that is broken or worn out and returns it to its original condition. Patching a roof leak, repainting a wall, or replacing a broken window is a repair. A repair does not increase the value of your home or extend its life significantly.

An improvement adds value, prolongs the life of the property, or adapts it to a new use. Installing a new roof (not patching the old one), adding a second bathroom, or finishing a basement are improvements. The line between the two is not always clear, and the IRS looks at the facts of each situation. If you are unsure whether something counts as a repair or improvement, keep all receipts and documentation—you may need them if the IRS questions your return.

How home improvements affect your sale price and taxes

When you sell your house, the IRS taxes the profit you make—the difference between what you paid for the house and what you sold it for. Home improvements increase the cost basis of your home, which lowers your taxable profit. If you spent $50,000 on improvements over the years you owned the house, your cost basis goes up by $50,000, which means your taxable gain goes down by $50,000.

This matters only if your total gain exceeds the exclusion limit. If you are single, you can exclude up to $250,000 of gain from tax. If you are married filing jointly, you can exclude up to $500,000. Most homeowners fall below these limits, so home improvements do not reduce their tax bill at sale—but keeping records is still wise in case your gain is large or the IRS questions your numbers.

To claim improvements on a future sale, you must have receipts, invoices, or other proof of what you spent. Contractor invoices, credit card statements, and bank records all work. Do not rely on memory or estimates. Store these documents safely for as long as you own the house.

Energy-efficient improvements and tax credits

Some home improvements may have access to for a federal tax credit, which is different from a deduction. A credit reduces your tax bill dollar-for-dollar, while a deduction only reduces your taxable income. Solar panels, heat pumps, electric water heaters, and certain insulation upgrades may may have access to for the Residential Energy Credit.

The credit covers a percentage of the cost—currently up to 30 percent for some improvements, though this percentage changes by year and by the type of improvement. You claim the credit on Form 5695 when you file your tax return. The credit is nonrefundable, meaning it cannot give you a refund larger than the tax you owe, but you can carry unused credit forward to future years.

To may have access to, the improvement must meet specific efficiency standards set by the IRS and the Department of Energy. The contractor or manufacturer usually provides a certification that the product meets these standards. Ask for this documentation before you pay, because without it you cannot claim the credit.

Home office and rental property improvements

If you use part of your home for business—a dedicated office, rental unit, or studio—improvements to that space may be deductible. You must calculate what percentage of your home is used for business. If your home office is 200 square feet and your house is 2,000 square feet, that is 10 percent.

You can deduct 10 percent of the cost of improvements that benefit the whole house, such as a new roof or HVAC system. Improvements made only to the business space—built-in shelving in your office, or a new kitchen in a rental unit—are fully deductible in the year you pay for them, or you may need to depreciate them over several years depending on the type of improvement and how you use the space.

The rules for business use are complex and depend on whether you are self-employed, run a rental property, or use the simplified home office deduction. Keep detailed records of what you spent, when you spent it, and which part of the house it benefits. If you claim a home office or rental deduction, you should work with a tax professional to make sure improvements are handled correctly.

What records to keep and how long to keep them

Keep receipts and invoices for every home improvement you make, even if you do not think you will need them. Store them in a safe place—a folder, a spreadsheet, or a digital file. Include the date, the contractor or vendor name, a description of the work, and the amount paid. If the improvement was large or involved multiple phases, keep a summary showing the total cost and what was done.

You should keep these records for at least three years after you sell the house, because that is how long the IRS can audit a return. If you think your gain at sale will be very large, keep records longer. Digital copies are fine, but make sure you have a backup in case you lose access to the file.

Common mistakes to avoid

One common mistake is treating a repair as an improvement or vice versa. If you replace a few shingles on your roof, that is a repair. If you replace the entire roof, that is an improvement. The IRS looks at the scope and cost of the work, not just the type of work. When in doubt, document what was done and why, so you can explain it if needed.

Another mistake is not keeping receipts. Without proof of what you spent, you cannot claim the improvement as part of your cost basis when you sell. A contractor's business card or a verbal agreement is not enough. Get a written invoice that shows the date, the work performed, and the amount paid.

A third mistake is confusing a tax deduction with a tax credit. A deduction lowers your taxable income. A credit lowers your tax bill. Energy-efficient improvements may may have access to for a credit, not a deduction. Make sure you are using the right form and claiming the right benefit.

Frequently Asked Questions

Can I deduct the cost of a new roof or HVAC system?

No, not in the year you pay for it. These are improvements, not repairs, so you cannot deduct them as a current expense. You can use the cost to increase your home's basis, which lowers your taxable gain if you sell the house later. If you use part of your home for business, you may be able to deduct a percentage of the cost.

What if I paid for improvements with a home equity loan?

The loan itself does not change the tax treatment of the improvement. You still cannot deduct the improvement cost. However, you may be able to deduct the interest you pay on a home equity loan if you use the money to improve the home and meet other IRS requirements. Consult a tax professional about your specific situation.

Do I need to report home improvements on my tax return?

No, not in the year you make them. You only report improvements when you sell the house, and then only if your total gain exceeds the exclusion limit. If you claim a home office or rental deduction, you may need to report improvements related to that space on your return.

Can I claim a solar panel installation as a deduction?

Solar panels may may have access to for the Residential Energy Credit, which is a credit, not a deduction. You claim it on Form 5695. The credit covers a percentage of the cost. This is different from claiming the improvement as part of your cost basis when you sell.

What happens if I cannot find receipts for old improvements?

Without receipts, you cannot prove the cost to the IRS. If you sell the house and your gain is large, the IRS may question improvements you claim. Try to find old invoices, credit card statements, or bank records. If you truly cannot locate proof, you may need to estimate based on what you remember, but this is risky if the IRS audits you.
