Most home improvements are not tax deductible, but a few specific types may reduce your taxable income

The IRS treats home improvements differently from home repairs. A repair fixes something broken or worn—replacing a roof shingle, patching drywall, repainting a room. Those are not deductible on your personal tax return. An improvement adds value, prolongs the life of your home, or adapts it to a new use—a new roof, an addition, or a kitchen renovation. Most improvements are also not deductible when you live in the home.

The main exception is energy-efficient improvements. If you install certain insulation, windows, doors, roofs, or heating and cooling systems that meet federal efficiency standards, you may claim a tax credit (not a deduction) of up to 30 percent of the cost, capped at $3,200 per year through 2032. A credit is better than a deduction because it reduces your tax bill dollar-for-dollar rather than reducing your taxable income.

If you sell your home later, you also will not owe capital gains tax on the value added by improvements—but that is not a deduction; it is a reduction in your profit when you sell. Medical modifications to your home, such as ramps or grab bars, may be deductible as medical expenses if your total medical costs exceed 7.5 percent of your adjusted gross income, but only the portion above that threshold counts.

Key Takeaways

  • Home improvements that add value to your home are generally not tax deductible when you live there, even if they cost thousands of dollars.
  • Energy-efficient improvements—insulation, windows, doors, roofs, and HVAC systems meeting federal standards—may may have access to for a 30 percent tax credit up to $3,200 per year through 2032.
  • A tax credit reduces your tax bill directly, while a deduction only reduces your taxable income, making credits more valuable.
  • Medical home modifications may be deductible as medical expenses only if your total medical costs exceed 7.5 percent of your adjusted gross income.
  • When you sell your home, improvements reduce your capital gains tax by increasing your cost basis, but this is not a deduction on your current return.

Energy-Efficient Improvements and the 30 Percent Tax Credit

The Inflation Reduction Act expanded the tax credit for energy-efficient home improvements starting in 2023. If you install a new roof with may have access to materials, add insulation to your attic or walls, replace windows or exterior doors, or upgrade your heating, cooling, or water heating system, you may claim 30 percent of the cost as a credit against your federal income tax.

The improvement must meet Department of Energy efficiency standards. Your contractor or the product manufacturer can tell you whether a specific item qualifies. The credit is capped at $3,200 per year, and the limit applies to all energy improvements combined in a single tax year. If you spend $10,000 on may have access to improvements, you can claim $3,000 (30 percent of $10,000), but only $3,200 of that credit can reduce your tax bill in one year. The remainder does not carry forward to future years.

You claim this credit on IRS Form 5695 when you file your return. You do not need to itemize deductions to use it. The credit is available to homeowners and applies to your primary residence only, not rental properties or vacation homes.

Repairs Versus Improvements: Why the Difference Matters

The IRS distinguishes between repairs and improvements based on whether the work restores your home to its original condition or adds something new. Replacing a broken window is a repair. Installing new energy-efficient windows is an improvement. Patching a roof leak is a repair. Replacing the entire roof is an improvement.

This distinction matters because repairs are not deductible on your personal return, but they do not add to your cost basis either. Improvements increase your cost basis—the amount you paid for the home plus the cost of improvements. When you sell, your capital gain is the sale price minus your cost basis. A higher basis means a lower taxable gain.

In practice, the line blurs. If you repair a roof by replacing a few shingles, it is a repair. If you replace the entire roof, it is an improvement. If you replace the roof and upgrade to a more durable material that extends the roof's life beyond its original span, the IRS is more likely to treat it as an improvement. Keep receipts and document what work was done, because the IRS may question whether a large expense was truly a repair or an improvement.

Medical Home Modifications and the Medical Expense Deduction

Home modifications that help you or a family member with a disability or medical condition—ramps, grab bars, widened doorways, accessible bathrooms, stair lifts—may be deductible as medical expenses. However, the deduction applies only to the cost of the modification itself, not to any increase in your home's value.

To claim a medical expense deduction, your total medical expenses for the year must exceed 7.5 percent of your adjusted gross income (AGI). If your AGI is $60,000, you can deduct only the medical costs above $4,500. This threshold is high, and most people do not reach it unless they have significant medical bills in a single year.

You must itemize deductions on Schedule A to claim medical expenses. If you take the standard deduction instead, you cannot deduct medical home modifications. A tax professional can help you decide whether itemizing makes sense in your situation.

How Home Improvements Affect Your Cost Basis When You Sell

When you sell your home, the IRS taxes your profit—the sale price minus what you paid for the home and the cost of improvements. This profit is called a capital gain. Home improvements increase your cost basis, which lowers your taxable gain.

For example, if you bought your home for $300,000 and spent $50,000 on improvements, your cost basis is $350,000. If you sell for $450,000, your gain is $100,000, not $150,000. You owe capital gains tax on $100,000 instead of $150,000.

Most homeowners do not owe capital gains tax on the sale of a primary residence because the IRS excludes up to $250,000 of gain for single filers and $500,000 for married couples filing jointly. You must have owned and lived in the home for at least two of the five years before the sale. If your gain is below the exclusion limit, you owe no tax. If it exceeds the limit, you owe tax only on the excess.

This is not a deduction on your current tax return—it is a reduction in your taxable gain when you eventually sell. Keep records of all improvements and their costs so you can prove your cost basis to the IRS if you are audited.

Rental Properties and Home Office Improvements

If you own a rental property, the rules are different. Improvements to a rental home are deductible through depreciation over many years, not as a single deduction. You depreciate residential rental property over 27.5 years, meaning you deduct a portion of the improvement cost each year on your tax return.

Home office improvements follow a similar rule. If you use part of your home exclusively for business, you may deduct a portion of home improvements that benefit the office space. For example, if your office is 10 percent of your home's square footage and you upgrade the HVAC system, you can deduct 10 percent of the cost. You depreciate this deduction over the useful life of the improvement, typically 15 to 39 years depending on the type of work.

These deductions require you to file Schedule C (for self-employed income) or Schedule E (for rental income) and to maintain detailed records. A tax professional can help you calculate the correct deduction and may support you are depreciating improvements over the right time period.

What You Cannot Deduct and Common Mistakes

Homeowners often assume that any large expense related to their home is deductible. It is not. Landscaping, painting, new flooring, kitchen cabinets, countertops, and bathroom fixtures are improvements that add value but are not deductible on your personal return. Neither are swimming pools, decks, or patios, even though they increase your home's resale value.

Routine maintenance—cleaning gutters, servicing your HVAC system, power washing your siding—is not deductible. Neither are repairs made to prevent damage, such as treating your foundation for termites or sealing cracks in your driveway.

A common mistake is confusing a tax credit with a deduction. The energy-efficient home improvement credit is a credit, which is much more valuable than a deduction. Another mistake is failing to document improvements when you sell your home. If you cannot prove you spent $20,000 on a new roof, the IRS will not let you increase your cost basis by that amount. Keep all receipts, invoices, and contracts related to home improvements for as long as you own the home.

Frequently Asked Questions

Can I deduct the cost of a new kitchen or bathroom?

No. Kitchen and bathroom renovations are improvements that add value to your home but are not deductible on your personal tax return. When you sell your home, the cost of these improvements increases your cost basis, which reduces your capital gains tax, but that is not a current-year deduction.

What if I install solar panels on my home?

Solar panels may have access to for the 30 percent energy-efficient home improvement tax credit. You can claim 30 percent of the installation cost (up to $3,200 per year) as a credit against your federal income tax. This is one of the most valuable home improvements for tax purposes.

Do I have to itemize deductions to claim the energy-efficient home improvement credit?

No. The energy-efficient home improvement credit is a non-refundable tax credit that you can claim whether you itemize or take the standard deduction. It reduces your tax bill directly, making it available to almost all homeowners who make may have access to improvements.

Can I deduct home improvements if I use part of my home for business?

Yes, but only the portion of the improvement that benefits your business space. If you have a home office that is 10 percent of your home's square footage and you upgrade insulation, you can deduct 10 percent of the cost through depreciation over several years. You will need to file Schedule C or Schedule E and keep detailed records.

What happens to my home improvement deductions if I rent out my home later?

If you convert your home to a rental property, improvements you made while you lived there increase your cost basis for capital gains purposes. Going forward, new improvements to the rental property are deductible through depreciation. The rules change when the property's use changes, so consult a tax professional before converting a home to rental use.
