Home Improvements Tax Deductibles: What Homeowners Need to Know in 2026

Most home improvements don’t qualify for tax deductions in the year you make them. But that doesn’t mean there’s no tax benefit. Understanding home improvement tax deductions — the difference between a repair, an improvement, and a deductible expense — can save you real money, both now and when you sell.

Which Home Improvements Are Tax Deductible? Repairs vs. Improvements

The IRS draws a firm line between two categories:

• Repairs keep your home in good working condition — painting, fixing a leak, patching drywall. You can’t deduct these on a personal residence.
• Improvements add value, extend your home’s useful life, or adapt it to new uses — a new roof, a kitchen remodel, a new HVAC system, a room addition. You can’t deduct these immediately either, but they matter for taxes later.

Capital Improvements and Your Cost Basis

This is the benefit most homeowners overlook. Qualifying capital improvements add to your home’s “cost basis” — what you paid for the home, plus what you’ve invested in it since. A higher basis means less taxable profit when you sell.

IRC Section 121 lets single filers exclude up to $250,000 of home-sale profit from capital gains tax. Married couples filing jointly can exclude up to $500,000. To qualify, you need to have owned and lived in the home as your main residence for at least 2 of the 5 years before the sale. If your gain sits close to or above that threshold, documented capital improvements — a new roof, an addition, a renovated kitchen — shrink your taxable amount by raising your basis.

Keep receipts, invoices, and contracts for every improvement. Hold onto them for as long as you own the home, plus several years after you sell. (Full rules: IRS Topic No. 701, Sale of Your Home.)

Home Equity Loan and HELOC Interest: A Common Home Improvement Tax Deduction

You can deduct interest on a home equity loan or HELOC, but only under specific conditions:

• You must use the funds to buy, build, or substantially improve the home that secures the loan. Debt consolidation, tuition, or a car purchase won’t qualify.
• You must itemize deductions on Schedule A instead of taking the standard deduction.
• The deduction covers interest on combined mortgage acquisition debt up to $750,000 ($375,000 if you’re married filing separately).

The 2017 Tax Cuts and Jobs Act originally set these limits. The One Big Beautiful Bill Act (OBBBA), signed into law on July 4, 2025, made them permanent. So this framework isn’t scheduled to expire or revert.

Starting with the 2026 tax year, a genuinely new benefit kicks in too: homeowners who pay private mortgage insurance (PMI) can now deduct those premiums as part of their qualified residence interest, as long as the mortgage insurance contract was issued after 2006. The deduction starts phasing out at $100,000 AGI ($50,000 if married filing separately) and disappears completely by $110,000 AGI. (See IRS Publication 936, Home Mortgage Interest Deduction for the full rules.)

Energy-Efficient Improvement Credits: A Major Change

This is the most important update for anyone researching this topic, since a lot of existing content online is now outdated. The Energy Efficient Home Improvement Credit (Section 25C) and the Residential Clean Energy Credit (Section 25D) covered items like windows, doors, insulation, heat pumps, and solar panels. Under the OBBBA, both expired for improvements placed in service after December 31, 2025. Congress had previously scheduled them to run through 2032.

Here’s what this means in practice:

• If you completed qualifying upgrades in 2025, you can still claim the credit on your 2025 return using IRS Form 5695.
• If your upgrades happen in 2026 or later, these specific federal credits no longer apply.
• A separate credit for home EV charging equipment (Section 30C, up to $1,000, available only in eligible low-income or non-urban census tracts) held on as the last federal residential clean-energy incentive still standing. It expired June 30, 2026, so it’s gone too now.

Medical Home Improvements

Say you modify your home for medical reasons — wheelchair ramps, widened doorways, grab bars, lowered countertops, modified stairways. IRS Publication 502 lets you deduct these costs as a medical expense, with one catch: you can only deduct the portion that doesn’t increase your home’s value, which may require an appraisal to establish. You also need your total unreimbursed medical expenses to exceed 7.5% of your adjusted gross income before any of it counts, and you must itemize.

Home Office Improvements

Right now, only the self-employed — freelancers, independent contractors, and small business owners filing Schedule C — can claim the home office deduction. W-2 employees who work from home, even full-time, can’t claim it under current law. The 2017 tax law eliminated this option for employees, and it hasn’t come back.

If you do qualify, your space needs to meet two tests: regular use and exclusive use for business. Improvements to that specific space, plus a proportional share of mortgage interest, utilities, and insurance, may be deductible.

Rental and Landlord Improvements

If you rent out all or part of your property, the rules shift:

• You generally depreciate improvements to the rental portion over time instead of deducting them all at once.
• You can typically deduct ordinary maintenance and repair costs on a rental unit as business expenses in the year you incur them.

The Bottom Line

For most owner-occupied homes, the real payoff from home improvement tax deductions shows up in one of three places: a higher cost basis at sale, deductible interest on a home equity loan used for qualifying work, or a medical or home-office deduction in narrower cases. The broad energy-efficiency credits that made headlines in past years are gone for 2026 and beyond. It’s worth setting expectations accordingly.
