IRS Home Renovation Tax Deduction 2026

A standard cosmetic kitchen remodel for personal use is not deductible in 2026 — it is a capital improvement that increases your cost basis (reducing future capital gains tax when you sell). However, three exceptions apply: (1) the kitchen serves a qualified home office (Section 280A allows depreciating the business-use portion); (2) the modifications are medically necessary (lowered counters, accessible appliances for a disabled household member documented by a physician — Schedule A, subject to 7.5% AGI floor); (3) the property is a rental, in which case the full remodel is depreciable over 27.5 years under MACRS.

For 2026 planning, do not assume a new federal 25C credit. IRS FS-2025-05 says Public Law 119-21 accelerated the termination of Section 25C, and the Energy Efficient Home Improvement Credit is not allowed for qualifying property placed in service after December 31, 2025. For work completed by the 2025 cutoff, the prior 30% framework and annual caps may still matter, including qualified manufacturer and product identification requirements. For 2026 work, verify the current IRS page first, then check state, local, and utility rebate programs separately.

Section 25C historically covered energy-efficiency upgrades such as insulation, windows, qualifying HVAC, heat pumps, heat-pump water heaters, biomass stoves, and audits. Section 25D historically covered residential clean-energy property such as solar, solar water heating, geothermal, wind, fuel cells, and battery storage. For 2026 projects, the key update is the cutoff: IRS FS-2025-05 says 25C is not allowed for property placed in service after December 31, 2025, and 25D is not allowed for expenditures made after December 31, 2025. If your project straddles 2025 and 2026, ask a tax professional to review contract, payment, installation, placed-in-service, and expenditure timing.

Yes, when medically necessary and prescribed by a physician. Qualifying modifications include wheelchair ramps, widened doorways (32"+), grab bars, walk-in showers, stair lifts, lowered cabinets, and entrance lifts. Two paths: (1) Schedule A medical expense deduction — full cost is deductible to the extent it does NOT increase the home value (e.g., a $15,000 stair lift that adds $5,000 of home value yields a $10,000 deductible expense), subject to the 7.5% AGI floor; (2) capital improvement basis adjustment for the value-increasing portion. Documentation: physician letter prescribing the modification, before/after appraisal for value impact, and itemized contractor invoices.

Home-office renovation deductions are primarily relevant for self-employed taxpayers with a space used regularly and exclusively for business. Improvements to the dedicated office space may be depreciated or allocated by business-use percentage, while repairs may be deductible depending on facts. Employees generally should not assume a federal deduction for unreimbursed home-office renovations. Because depreciation, mixed-use allocation, and recapture can be complex, have a CPA review material renovations before claiming them.

Repairs are generally deductible in the year incurred on Schedule E, while improvements must usually be capitalized and depreciated. Fixing a leak, replacing a broken fixture, or repainting after tenant turnover may be a repair. A kitchen remodel, new roof, room addition, HVAC replacement, or major upgrade is usually an improvement. Residential rental improvements are commonly depreciated over 27.5 years, while commercial property rules differ. De minimis safe harbor, routine maintenance, cost segregation, and qualified improvement property rules are fact-specific, so treat large rental renovations as CPA-review items.

A standard roof replacement on a personal residence is usually not an immediate deduction; it is a capital improvement that adjusts cost basis. For 2026 projects, do not assume federal 25C or 25D availability for roof-related energy claims after the IRS cutoff. If the property is a rental, a roof is usually capitalized and depreciated rather than deducted immediately. If a project includes solar roofing or another energy component that started before the cutoff, review the exact IRS timing rules with a tax professional.

Capital improvements (not repairs) increase your adjusted cost basis, reducing capital gains tax when you sell. Qualifying additions per IRS Pub 523: room additions, finished basement, deck/patio, fence, swimming pool, central AC installation, new roof, water heater, septic system, landscaping (permanent), driveway paving, storm windows/doors, security system, kitchen/bath remodels. Keep receipts indefinitely until 3 years after you sell. Single filers exclude $250,000 of gain ($500K married filing jointly) under Section 121 if you owned and lived in the home 2 of the last 5 years. Example: $400K purchase + $80K renovations = $480K basis; sold for $700K = $220K gain, fully excluded for MFJ.

For 2026 projects, start by verifying whether a federal credit is available at all after the 25C/25D cutoff. Many projects may rely on state, utility, manufacturer, or income-qualified rebate programs instead. If a federal credit does apply to a prior-year or transition project, rebates can affect eligible basis and ordering. Keep invoices, product certificates, rebate documents, proof of payment, placed-in-service records, and written contracts so a tax professional can verify the correct treatment.
