Most home improvements don’t qualify for a tax deduction or credit. However, energy-efficient upgrades (installed by December 31, 2025), home equity loan interest, home office improvements, medically necessary modifications, and capital improvements can all reduce your federal tax burden either now or when you sell.
- The energy-efficient home improvement credit expired at the end of 2025, but you can still claim it if your improvements were completed by December 31, 2025.
- If you took out a Home Equity Loan or HELOC to improve your home, the interest may be deductible if you itemize.
- Capital improvements won’t give you a deduction today, but they lower your taxable gain when you eventually sell your home.
Are Home Improvements Tax Deductible?
Most home improvements are not directly deductible on your federal return.
But “most” isn’t “all.”
There are five real ways home improvements can reduce your tax bill, and knowing the difference could save you hundreds, or even thousands of dollars.
1. Energy-Efficient Tax Credits (For 2025 Improvements)
This one comes with an important 2026 update:
The Federal Energy Efficient Home Improvement Credit under IRS Code Section 25C has expired for new improvements made after December 31, 2025.
What that means for you:
- If you completed qualifying energy-efficient upgrades by December 31, 2025, you can still claim the credit on your 2025 tax return (filed in 2026).
- If your upgrades happened in 2026 or later, there is currently no federal tax credit available under this program.
If You Qualify (2025 Improvements)
The Section 25C credit allowed homeowners to claim up to $3,200 for qualified energy-efficient improvements installed by December 31, 2025, covering 30% of eligible costs.
Here’s how the credit limits broke down:
- Up to $1,200 for general energy-efficient improvements (windows, doors, insulation, energy audits)
- $250 per qualifying exterior door ($500 total)
- $600 for qualifying windows and skylights
- $150 for a home energy audit
- Up to $2,000 for qualifying heat pumps, heat pump water heaters, and biomass stoves/boilers
To claim this credit for your 2025 improvements, file IRS Form 5695 with your 2025 tax return. Note: in 2025, homeowners were required to report a Qualified Manufacturer Identification Number (QMID) for eligible products on their tax return.

2. Home Mortgage Interest Deduction
If you used a Home Equity Loan or a Home Equity Line of Credit (HELOC) to fund home improvements, the interest you paid may be deductible — but two conditions must be met.
Condition 1: The Loan Must Be Used for a Qualifying Purpose
The IRS requires that the loan be used to “buy, build, or substantially improve” the home that secures the debt. Using your HELOC to renovate your kitchen or add a bathroom? Likely qualifies. Using it to pay off credit card debt? Does not qualify.

Condition 2: You Must Itemize Your Deductions
The interest deduction is only available if you itemize on Form 1040, Schedule A instead of taking the standard deduction.
Here’s a quick example using 2026 numbers:
Let’s say you paid $10,800 in qualifying HELOC interest and $6,200 in property taxes in 2026.
- Your itemized deductions total: $17,000
- The 2026 standard deduction for a single filer: $16,100
In this scenario, itemizing your deductions gives you a slightly larger deduction, meaning your HELOC interest helped increase your eligible deductions.
3. Home Office Deduction
If you have a space in your home used exclusively and regularly for business, you may qualify for the home office deduction. This lets you deduct a portion of your home expenses—including mortgage interest, utilities, insurance, and depreciation—based on the percentage of your home dedicated to business use.
You have two options for calculating the deduction:
Regular (Actual Expense) Method: Track your actual home expenses and deduct the business-use percentage of indirect expenses, plus 100% of direct expenses to the office itself.
Simplified Method: Deduct $5 per square foot of the home office (up to 300 square feet, for a maximum of $1,500), with no need to track actual expenses or allocate percentages.
Here’s the part that directly applies to home improvements:
Under the regular method, improvements made specifically to your home office space are treated as direct expenses and are 100% deductible as a business expense—not just a percentage based on square footage.
The simplified method does not allow separate deductions for home improvements.
For example, if you renovated a dedicated home office that makes up 12% of your home’s square footage, 100% of those renovation costs could be deductible as a direct business expense under the regular method (not just 12%). However, improvements made to the entire home (like a new roof or HVAC system) are only deductible at your business-use percentage (12% in this example).

4. Medical Home Improvements
Sometimes a home improvement isn’t about aesthetics… it’s a medical necessity. Think wheelchair ramps, grab bars, or doorway widening for a family member with a disability.
When home modifications are made primarily for medical reasons, you may be able to deduct a portion of the cost as a medical expense, subject to the AGI threshold. The IRS allows you to deduct qualified medical expenses that exceed 7.5% of your Adjusted Gross Income (AGI).
Qualifying Medical Home Improvements (per IRS Publication 502)
The IRS includes these examples of potentially deductible medical modifications:
- Moving or modifying electrical outlets and fixtures
- Adding handrails or grab bars anywhere in the home
- Widening hallways and interior doorways
- Installing railings, support bars, or bathroom modifications
- Lowering or modifying kitchen cabinets and equipment
Important: The deductible amount is generally limited to the cost that exceeds any increase in your home’s fair market value. Keep all receipts, invoices, and any documentation from a medical professional recommending the modification. A tax professional can help you calculate the deductible portion correctly.
5. Capital Improvements
Capital improvements are upgrades that add value to your home or extend its useful life. Think a new roof, added square footage, a renovated kitchen, or a new HVAC system.
These aren’t deductible today. But they matter at tax time when you sell.
How It Works: The Tax Basis Strategy
Here’s the concept: when you sell your home, you owe capital gains tax on the profit. Your tax basis is what you paid for the home plus qualifying capital improvements.
The higher your tax basis, the lower your taxable gain.
Quick example:
- You bought your home for $300,000
- You added $50,000 in capital improvements over the years
- Your adjusted tax basis is now $350,000
- You sell for $500,000
- Your taxable gain is $150,000 — not $200,000
That $50,000 difference could save you thousands in capital gains taxes.
Important: Section 121 Exclusion
Before worrying about capital gains on your home sale, know that IRS Section 121 lets you exclude up to $250,000 of gain ($500,000 for married filing jointly) if you owned and lived in the home as your primary residence for at least 2 of the last 5 years. This means most homeowners won’t owe any capital gains tax on their home sale if they qualify for the exclusion.
Key takeaway: Capital improvements still matter even with Section 121 — if your gain exceeds the exclusion limit, or if you don’t qualify (e.g., rental property, second home, or didn’t meet the 2-year test), the higher basis from improvements reduces your taxable gain.
The action item: Save every invoice, permit, and receipt for capital improvements. You’ll need them when you sell.
Frequently Asked Questions
Can I deduct home improvements on my 2026 tax return?
Generally, no. Home improvements are not directly deductible. However, improvements made by December 31, 2025 may qualify for the Section 25C energy credit, and capital improvements can reduce your capital gains when you sell.
The energy-efficient tax credit expired. Are there any other federal incentives?
As of 2026, the Section 25C and 25D credits have expired. There are currently no direct federal replacement credits for homeowners. Check your state. several states offer their own energy efficiency incentives.
What’s the difference between a tax credit and a tax deduction?
A tax credit directly reduces your tax bill dollar-for-dollar. A tax deduction reduces your taxable income, which then reduces your tax bill — but by a smaller amount depending on your tax bracket. Credits are generally more valuable.
Do I need to itemize to claim home improvement benefits?
It depends on the benefit. The HELOC interest deduction requires itemizing. The energy credit (for 2025 improvements), medical expense deduction, and home office deduction do not require itemizing — though the medical deduction also has an AGI floor.
What counts as a capital improvement vs. a repair?
A capital improvement adds value to your home, adapts it to new uses, or extends its useful life (new roof, kitchen addition). A repair simply maintains the home’s current condition (fixing a leaky pipe). Capital improvements increase your tax basis; repairs generally do not.
