Can You Write Off Home Improvements on Your Taxes?

“Can you write off home improvement costs?” is one of the most searched tax questions among homeowners, and the answer is the classic tax-professional response: it depends. Most personal-home renovations are not directly deductible, but several important exceptions can save you real money. Here is what actually counts.

The Short Answer

Improvements to your primary personal residence are generally not tax-deductible in the year you pay for them. You cannot deduct a kitchen remodel the way a business deducts expenses. However, improvements can reduce your taxes later in three powerful ways: by increasing your cost basis (lowering capital gains when you sell), through energy tax credits, and via medical-expense deductions for accessibility modifications.

Exception 1: Capital Improvements Reduce Capital Gains

Every qualifying capital improvement adds to your home’s cost basis. When you sell, a higher basis means a lower taxable gain. A $40,000 addition on a home you bought for $300,000 raises your basis to $340,000 (plus other improvements). With the $250,000/$500,000 home-sale exclusion, many sellers owe no gain tax anyway, but in high-appreciation markets this record-keeping pays off enormously.

Keep receipts for everything, forever (or at least until three years after you sell). The IRS wants proof of what you spent.

Exception 2: Energy-Efficient Upgrades Earn Credits

The federal energy-efficient home improvement credit covers 30% of qualifying costs (up to annual caps) for items like heat pumps, insulation, energy-efficient windows and doors, and home energy audits. Unlike deductions, credits reduce your tax bill dollar for dollar. State programs stack on top; check the grants guide for state-level help.

Exception 3: Medically Necessary Modifications

Home modifications prescribed for a medical condition (wheelchair ramps, widened doorways, accessible bathrooms) can be deductible as medical expenses to the extent they exceed 7.5% of adjusted gross income and do not increase the home’s value. Modifications that do add value are only deductible above the value increase. Get the medical necessity documented in writing.

Exception 4: Home Office and Rental Portions

If part of your home is a dedicated home office or a rental unit, improvements to that portion may be deductible or depreciable. A new HVAC system for the whole house gets partially allocated; a renovation of the rented basement unit is fully a rental expense. See our home office ergonomics guide for workspace upgrades.

Exception 5: HELOC Interest (Sometimes)

Interest on a HELOC or home equity loan is deductible if the funds are used to buy, build, or substantially improve the home securing the loan, subject to the $750,000 total mortgage debt limit. Using HELOC money for a vacation or car? Not deductible. Details matter, so track exactly where borrowed funds go (see HELOC vs. home equity loan).

What Never Counts

• Routine repairs and maintenance (fixing a leak, repainting) — these are not improvements.
• Improvements with no documentation — no receipt, no basis increase.
• DIY labor value — only materials and paid labor count toward basis.

Frequently Asked Questions

Is a new roof tax deductible?

Not directly on a personal residence, but it adds to your cost basis and may qualify for energy credits if you install qualifying reflective or solar roofing.

Do I need receipts for home improvements?

Yes. Keep every receipt, contract, and permit. Digital copies in cloud storage are fine. You may need them years later when you sell.

Can I deduct improvements made before I sell?

Pre-sale improvements are generally not deductible as selling expenses, but they still increase your basis and can boost the sale price. Talk to a tax pro about timing.

Does this article replace tax advice?

No. Tax law changes and individual situations vary. Use this as a starting framework and confirm with a qualified tax professional before filing.
