Most home upgrades are not tax deductible, but some repairs and improvements tied to medical needs or business use may be

The IRS treats home upgrades differently depending on what they are and why you did them. A new roof, kitchen remodel, or fresh paint on your house is almost never deductible—those are considered personal expenses or capital improvements that increase your home's value, and you can only recover that cost when you sell. But if you install a wheelchair ramp because you have a disability, or you convert a bedroom into a home office for work, parts of that cost may reduce your taxable income in the year you complete the work.

The line between a deductible expense and a non-deductible one is specific. The IRS looks at whether the upgrade is medically necessary, whether it adds value to your home beyond the medical purpose, and whether it is tied to income-producing activity. A grab bar installed for safety in a bathroom is treated differently than a full bathroom renovation. Understanding which category your project falls into before you start work can save you from missing a deduction or claiming one you cannot defend.

Key Takeaways

  • Home upgrades that increase your home's resale value—kitchens, bathrooms, roofing, flooring—are not deductible in the year you do them, though you may reduce capital gains tax when you sell.
  • Medical home modifications like wheelchair ramps, grab bars, and walk-in showers may be deductible as medical expenses if they exceed 7.5% of your adjusted gross income and you itemize deductions.
  • Home office expenses are deductible only if you use a dedicated room or space exclusively for business, and only the portion of utilities, depreciation, and repairs tied to that space.
  • Energy-efficient upgrades like solar panels, heat pumps, and insulation may may have access to for federal tax credits (not deductions), which directly reduce the tax you owe rather than reducing your income.
  • You need documentation—receipts, invoices, and medical certification for disability-related work—to support any deduction you claim.

Medical home modifications and the 7.5% threshold

If you install a home modification because of a medical condition or disability, you may deduct the cost as a medical expense on Schedule A (if you itemize deductions). The IRS allows this only if the modification is medically necessary and does not add significant value to your home beyond the medical purpose. A wheelchair ramp built to allow access is deductible. A full bathroom renovation that happens to include a walk-in shower is not, unless the walk-in shower is the only way you can bathe safely due to a documented condition.

The catch is the 7.5% threshold. You can only deduct medical expenses that exceed 7.5% of your adjusted gross income (AGI). If your AGI is $60,000, you can deduct medical expenses only above $4,500. This means a $3,000 grab bar installation would not be deductible on its own, but if you also had other medical expenses that year—prescriptions, therapy, medical equipment—the total might cross the threshold. You will need a letter from your doctor stating that the modification is medically necessary, not just convenient.

Home office deductions and the exclusive-use rule

If you work from home, you can deduct expenses tied to your home office, but only if you use that space exclusively for business. You cannot deduct a portion of your bedroom if you also sleep there. You can deduct a spare room you converted into an office, or a finished basement corner you use only for work. The IRS has two methods: the simplified method (a flat $5 per square foot, up to 300 square feet) or the actual expense method (a percentage of your home's utilities, insurance, repairs, and depreciation based on the office's square footage).

If you use the actual expense method, you will need to calculate what percentage of your home the office occupies. A 200-square-foot office in a 2,000-square-foot house is 10%, so you can deduct 10% of your mortgage interest (or rent), property taxes, utilities, insurance, and repairs. You can also deduct 100% of expenses that benefit only the office—a new desk, office equipment, or repairs to that room alone. Keep receipts and document the square footage of both your office and your entire home.

Energy-efficient upgrades and federal tax credits

Solar panels, heat pumps, insulation, and certain HVAC and water heater upgrades may may have access to for federal tax credits under the Inflation Reduction Act. These are credits, not deductions—they reduce the tax you owe dollar-for-dollar, which is more valuable than reducing your taxable income. A $3,000 credit means you owe $3,000 less in tax. A $3,000 deduction reduces your taxable income by $3,000, saving you tax only on that amount (usually 12% to 37%, depending on your bracket).

The credits vary by upgrade. Solar installations may may have access to for a 30% credit. Heat pump water heaters, air-source heat pumps, and certain insulation projects may may have access to for credits up to $2,000 or $3,600 depending on the equipment and your income. You must file Form 5695 (Residential Energy Credits) or Form 8908 (Energy Efficient Home Improvement Credit) with your tax return. The equipment must meet Department of Energy specifications, and you must be the homeowner (not a renter). Check the ENERGY STAR website or the IRS website for current equipment lists and credit amounts, as these change year to year.

Capital improvements and the cost basis when you sell

A capital improvement is a home upgrade that adds value, prolongs the life of your home, or adapts it to a new use. A new roof, kitchen remodel, deck, or finished basement are all capital improvements. You cannot deduct them in the year you do the work. Instead, you add the cost to your home's cost basis—the original purchase price plus improvements. When you sell, your capital gain is the sale price minus your cost basis. A higher basis means a lower taxable gain.

If you bought your house for $300,000 and spent $50,000 on a kitchen remodel, your basis is $350,000. If you sell for $500,000, your capital gain is $150,000, not $200,000. You save tax on that $50,000 difference. Keep all receipts and invoices for capital improvements. The IRS may ask you to prove the work was done and what it cost. Repairs—fixing a broken window, patching a roof leak, repainting—are not capital improvements and are not deductible for homeowners, though they do not add to your basis either.

Repairs versus improvements: why the distinction matters

The IRS distinguishes between repairs (maintaining your home in its current condition) and improvements (upgrading or extending its life). A repair is not deductible for a homeowner and does not add to your basis. An improvement adds to your basis but is not deductible in the year you do it. This distinction is not always clear. Replacing a few shingles on a roof is a repair. Replacing the entire roof is an improvement. Patching drywall is a repair. Renovating a room is an improvement.

The IRS looks at whether the work restores your home to its original condition or goes beyond that. If a pipe bursts and you replace it with the same type of pipe, that is a repair. If you replace it with a new water line that serves the whole house more efficiently, that is an improvement. If you are unsure, document what you did and why. Take photos before and after. Keep the contractor's invoice and description of the work. If the IRS questions you, you will need to show that the work was necessary maintenance, not an upgrade.

Rental property and business-use deductions

If you rent out a room or a portion of your home, or if you run a business from your home, the rules are different from a primary residence. Upgrades to a rental unit or a business space may be deductible as business expenses in the year you do them, or they may be depreciated over several years. A new roof on a rental property is a capital improvement, but you can deduct a portion of it each year through depreciation. A repair to a rental unit is fully deductible in the year you do it.

If you rent out one room in your home, you can deduct a percentage of your home's expenses—utilities, insurance, repairs, depreciation—based on the square footage of the rental room. If you run a business from a dedicated space, you can deduct expenses tied to that space. The rules are complex and depend on how much of your home is used for business or rental. If you have rental income or self-employment income from your home, consult a tax professional or refer to IRS Publication 587 (Business Use of Your Home) or Publication 527 (Residential Rental Property).

Documentation and what the IRS expects to see

Any deduction you claim must be backed by documentation. For medical modifications, keep the receipt or invoice, the contractor's description of the work, and a letter from your doctor stating that the modification is medically necessary. For home office deductions, document the square footage of your office and your entire home, and keep receipts for equipment and supplies. For energy credits, keep the receipt and the manufacturer's certification that the equipment meets ENERGY STAR or Department of Energy standards.

The IRS does not require you to attach receipts to your return, but you must keep them for at least three years (six years if you underreport income by 25% or more). If you are audited, you will need to produce them. For large projects—a major renovation, a solar installation, or a significant home office setup—take photos and keep a detailed record of what was done, when, and by whom. If you hire a contractor, get a written estimate before the work starts and a detailed invoice after it is complete. If you do the work yourself, keep receipts for materials and document your time and labor.

Frequently Asked Questions

Can I deduct the cost of painting my house or replacing the kitchen?

No. Painting, kitchen remodels, and other upgrades that increase your home's value are capital improvements, not deductible expenses. You add the cost to your home's cost basis, which reduces your taxable capital gain when you sell. If you sell for a profit, a higher basis means you owe less tax on that profit.

What if I install a wheelchair ramp and later sell my house—can I deduct it?

A wheelchair ramp installed for medical necessity may be deductible as a medical expense in the year you install it (if your total medical expenses exceed 7.5% of your AGI). You cannot deduct it again when you sell. If the ramp does not add significant value to your home, it may not add to your cost basis either, so you get the deduction without reducing your capital gain.

Do I need to report energy credits on my taxes?

Yes. You file Form 5695 or Form 8908 with your tax return to claim energy credits. The form asks for the type of equipment, the cost, and the manufacturer's certification that it meets federal standards. You must have the receipt and certification to support the credit if you are audited.

Can I deduct home repairs if I work from home?

Only if the repair is to your home office space and you use that space exclusively for business. A repair to the rest of your home is not deductible. If you repair the roof and your home office is on the second floor, you can deduct a percentage of the roof repair based on the office's square footage of your home.

What happens if I claim a deduction and the IRS disagrees?

The IRS may disallow the deduction and ask you to pay back taxes plus interest. If you cannot produce documentation, the deduction will be denied. If the IRS determines you claimed a deduction you were not may have access to to, you may also owe a penalty. This is why documentation and understanding the rules before you claim a deduction is important.
