Home Improvements vs. Repairs: How They Change Your Home's Basis
Published November 6, 2026
Your home's basis is the starting point for figuring gain or loss when you sell. Publication 530 (2025), Tax Information for Homeowners, explains which costs change that basis. This guide is general information. It is not advice about your return.
Repairs keep the home working
The publication says a repair keeps your home in ordinary, efficient operating condition. A repair does not add to the value of your home or prolong its life. Examples of repairs include repainting, fixing gutters or floors, fixing leaks, and replacing broken window panes.
The publication says you cannot deduct repair costs, and you generally cannot add them to your home's basis. There is one exception. Repairs done as part of an extensive remodeling or restoration count as improvements.
Improvements add to basis
The publication says an improvement adds materially to value, extends useful life, or adapts the home to new uses. Examples include an addition, a new roof, a paved driveway, central air conditioning, and rewiring.
The publication says you add the cost of improvements to your home's basis. The amount is your actual cost, including material and labor, except your own labor. It also includes related expenses. For example, a survey done before building a fence is part of the fence's cost.
Local assessments for improvements, like streets and sidewalks, can also be added to basis if they raise the property's value.
Replaced items leave the basis
The publication says basis does not include the cost of improvements that were replaced. For example, once you replace wall-to-wall carpeting, the old carpeting's cost leaves your home's adjusted basis.
Items that lower basis
Publication 530 has a table of events that adjust basis. Some events lower it. The table includes insurance payments for casualty losses, business or rental depreciation, and payments for an easement or right-of-way.
Two other items also lower basis. First, if a public utility gave you a subsidy for an energy conservation measure, do not count it as income. Reduce your basis by the same value. Second, if you claimed an adoption credit for costs added to basis, reduce basis by the credit.
Energy credits and basis
The publication says the energy efficient home improvement credit covers property placed in service through December 31, 2025. It also says any basis increase for energy property must be reduced by any credit you take. See Form 5695 for the credit rules. Our guide to the home-sale exclusion explains how basis fits into a later sale.
Keep records of every change
The publication says to keep receipts, canceled checks, and similar evidence for improvements. Track decreases to basis too. You may need basis records longer than the usual period, since they matter whenever you sell.
Keep the records clear, accurate, and available to the IRS. Keep the purchase papers too. If you got the home as a gift, see our guide to gifted property.
A simple test
Ask whether the work made the home better, added to its value, or made it last longer. If so, it is likely an improvement. If the work only kept the home in working order, it is a repair. Some projects mix both. Keep separate receipts when you can.
Mortgage interest and points
Costs such as mortgage interest and points have their own deduction rules, separate from the basis rules above. Our guide to the mortgage interest deduction and Form 1098 covers that topic.
Simple steps
- Sort each home cost as a repair or an improvement.
- Add the actual cost of improvements, including labor and related expenses, to your basis.
- Remove the cost of any item you replaced and no longer have.
- Reduce basis for items such as casualty reimbursements, business depreciation, and energy subsidies.
- Keep receipts and a running record of basis changes for as long as they matter.
