Are home improvements deductible?

Improvement versus repair

The deduction question turns on a distinction Publication 530 draws in one short passage. An improvement materially adds to the value of the home, considerably prolongs its useful life, or adapts it to new uses. Its examples include putting a recreation room in an unfinished basement, adding another bathroom or bedroom, putting up a fence, putting in new plumbing or wiring, installing a new roof, and paving a driveway. Table 3 adds putting an addition on the home, replacing an entire roof, installing central air conditioning, and rewiring.

A repair keeps the home in an ordinary, efficient operating condition. It does not add to the value or prolong the life. The publication lists repainting inside or outside, fixing gutters or floors, fixing leaks or plastering, and replacing broken window panes. Repair costs cannot be deducted for a personal home, and they generally cannot be added to basis either. Repairs to the home also appear on the publication's list of nondeductible payments.

The one exception: repairs inside a remodel

There is a catch that changes treatment. Repairs done as part of an extensive remodeling or restoration of your home are considered improvements, and you add them to the basis of your home. If you gut a kitchen and, as part of that project, fix the floor and replaster, those costs ride along with the improvement. The same repair done alone, on an otherwise untouched house, is not an improvement. The line is easier to defend when the invoice and permits describe one project.

How much goes into basis

The amount you add to basis for an improvement is your actual cost: all costs for material and labor, except your own labor, and all expenses related to the improvement. The publication's example: if you had your lot surveyed to put up a fence, the survey cost is part of the cost of the fence. You must also add state and local assessments for improvements such as streets and sidewalks if they increase the value of the property.

When an improvement leaves basis

Your home's adjusted basis does not include the cost of any improvements that are replaced and are no longer part of the home. The publication's example is wall-to-wall carpeting installed 15 years ago and later replaced: the cost of the old carpeting is no longer part of your adjusted basis. Table 4 in the publication tells you to remove from your improvement record anything that is no longer part of your main home.

What improvements do for you later

An improvement has no effect on this year's tax bill, but it increases the basis from which a later gain or loss is measured. The benefit shows up if you sell and the gain exceeds the exclusion for a main home, which Publication 523 covers, or if part of the home is later used for business or rent. For a home that will be sold at a gain, a bigger basis directly reduces taxable gain dollar for dollar. For a home that will be lived in for decades, the improvement may never produce a tax effect, which is no reason to throw away the receipts.

Special cases: energy and accessibility work

Some improvements trigger a credit, which has its own rules and a basis adjustment. Publication 530 says that when a residential energy credit is allowed, the increase in basis from the property is reduced by the credit taken. Energy credits for 2025 and the end of those credits are on our home energy credit page. If a public utility gives you a subsidy for an energy conservation measure and you exclude it from income, reduce the basis of the home by the subsidy.

Worked example with invented numbers

Original basis is $403,200 ($400,000 price plus $3,200 of closing costs that go into basis). Over six years you add a $22,000 bathroom, a $6,500 fence and a $9,000 driveway (all improvements, $37,500 total). You also pay $1,800 to repaint the exterior and $450 to fix the gutters. The paint and gutters are repairs, so they are not deducted and do not enter basis. Adjusted basis is $403,200 + $37,500 = $440,700. Had the painting been done as part of an extensive restoration of the home, its $1,800 would also be an improvement and the basis would be $442,500. Try it above by entering $37,500 as improvements.

Keep an improvement log

Publication 530 asks for a clear and accurate record of each improvement: type, date and amount, supported by receipts or canceled checks. Its Table 4 groups types into additions, heating and air conditioning, electrical, lawn and grounds and plumbing. Keep the records as long as they matter for figuring basis.
