Are Home Improvements Tax Deductible in 2026? Here's What Actually Counts
For most homeowners, a home improvement to the place you live counts as personal spending, so it earns no tax deduction the year you pay for it. A few real exceptions change that, and any one can be worth thousands: a medical-necessity modification, the basis boost that lowers your taxable gain at sale, and interest on a loan used to improve the home. This is not tax advice; just information for you. Every situation is different; make sure you speak with a tax expert before filing.
Key Takeaways
- Most improvements to your own home aren't deductible the year you pay for them. The tax code treats them as personal spending, not a business expense.
- Capital improvements, such as a new roof, an addition, or updated systems, add to your home's cost basis. That lowers the gain you're taxed on at sale, where the first $250,000 of gain for a single filer ($500,000 for joint filers) is already tax-free.
- Medical-necessity modifications are deductible as a medical expense, but only for the cost above any rise in your home's value, and only the portion of total medical costs above 7.5% of your adjusted gross income, if you itemize.
- Interest on a loan that buys, builds, or substantially improves your home is deductible within the $750,000 mortgage-debt cap, if you itemize. Money spent on anything else isn't.
- The two federal energy credits that once paid for part of efficiency and clean-energy upgrades have been repealed for newly installed projects. State and utility programs may still help.
- Records decide everything. Keep invoices, proof of payment, permits, and loan documents, and hold improvement records until at least three years after you sell.
- This is education, not tax advice. A CPA or enrolled agent should sign off on your specific situation.
The Short Answer, and Why There's More to It
Homeowners ask me some version of this question every spring: I just spent real money fixing up my house, so can I write it off? The short answer is usually no. Improvements to the place you live are treated as personal spending, and personal spending isn't deductible the year you do it.
That's the part most people don't want to hear. Here's the part worth sticking around for. Several real exceptions exist, and any one of them can be worth thousands of dollars if your project fits. A medical-necessity modification can come straight off your taxes. The money you spend improving the home quietly lowers what you'll owe when you sell. Interest on the loan you used to pay for the work may be deductible. And the way you paid for the project, whether cash, a refinance, or a home equity line, changes the answer more than people expect.
In more than two decades around mortgage lending, I've watched borrowers leave money on the table because nobody explained which bucket their project belonged in. So here's how the buckets sort out. By the end you'll be comfortable knowing what counts, what doesn't, and what to bring your tax preparer so they can finish the job. One honest caveat first: I'm a mortgage guy, not your accountant. Treat this as a map, not the last word.
The General Rule: Most Improvements Aren't Deductible the Year You Pay
Start with the rule that catches the most people off guard. When you improve the home you live in, the cost is a personal expense in the eyes of the tax code. Personal expenses don't get deducted on your return the year you incur them. New countertops, a finished basement, a remodeled bath: real money, real value, and no line on this year's tax form to claim it.
I understand why folks expect otherwise. You wrote a five-figure check to make your home better, and it feels like that ought to count for something at tax time. The confusion usually comes from mixing up two different ideas. A business gets to deduct what it spends to operate. A homeowner improving a personal residence is not running a business, so the same logic doesn't carry over.
Here's the more complete frame, and the reason this article keeps going. "Not deductible this year" is not the same as "wasted." The tax code rewards certain home spending, just on a different timeline and through different doors than people assume. Some costs come back to you when you sell. Some qualify because of a medical need. Some ride along with how you financed the work. The trick is knowing which door your project walks through before you spend, not after.
Improvements Versus Repairs, and Why the IRS Draws the Line
Almost every tax question about a home project turns on one distinction: is the work an improvement or a repair? The two are treated differently, so it pays to know which is which.
An improvement adds value to the home, prolongs its useful life, or adapts it to a new use. Putting on a new roof, adding a bathroom or a bedroom, finishing an unfinished basement, installing new plumbing or wiring, paving the driveway, or putting up a fence all count as improvements. These are the costs that can add to your basis and matter when you sell.
A repair keeps the home in good working order without adding value or extending its life. Fixing a leak, patching and repainting a wall, plastering, or replacing a cracked window pane are repairs. They keep the place running, but on their own they don't change your tax picture and they don't add to basis.
The line gets blurry in the middle, and that's where good records earn their keep. A repair done as part of a larger remodel can fold into the cost of the improvement. Swapping one broken windowpane is a repair; replacing every window in the house as part of a renovation reads as an improvement. The same dollar amount can land on either side of the line depending on the scope of the work and how you document it. When a project is large enough to matter, keep the invoices detailed enough to tell the story.
Where Improvements Pay Off: Your Cost Basis and the Home-Sale Exclusion
This is the payoff most homeowners miss, and it can be the biggest one. Capital improvements add to your home's adjusted basis, which is roughly what you have invested in the property. A higher basis means a smaller gain when you sell, and a smaller gain can mean a smaller tax bill, or none at all.
The home-sale rules let you exclude a generous chunk of gain on your main home. A single filer can exclude up to $250,000 of gain, and a married couple filing jointly can exclude up to $500,000. To qualify, you generally need to have owned the home for at least two of the five years before the sale and lived in it as your main home for at least two of those five years, and you can use the exclusion only once every two years.
Let me show the math, because the numbers make the point better than I can. Say you buy a home for $400,000. Over the years you put in $120,000 of qualifying improvements: a kitchen remodel, a room addition, and a new roof. Your adjusted basis climbs to $520,000. Later you sell for $760,000 and pay $40,000 in selling costs, so the amount you realize is $720,000. Your gain is $720,000 minus $520,000, or $200,000. As a single filer you exclude up to $250,000, so the entire $200,000 gain is tax-free.
Now run it without the improvements. Your basis would have stayed at $400,000, your gain would have been $320,000, and $70,000 of that would have landed above the single-filer exclusion. At a 15% long-term capital gains rate, that's roughly $10,500 in tax you didn't have to pay, simply because you tracked $120,000 of improvements over the years. Repairs, by contrast, don't add to basis, so the new coat of paint doesn't help you here.
One thing to remember: the tax applies to your gain, not the sale price. And the only way to prove your basis is with records, which is why the homeowners who win this game are the ones who kept the paperwork. Hold those improvement records for as long as you own the home, plus at least three years after you file the return reporting the sale.
Medical-Necessity Improvements: The Clearest Deduction
If a home improvement's main purpose is medical care for you, your spouse, or a dependent, part of the cost can be deductible as a medical expense. This is the cleanest path to an actual deduction, and it's the one people overlook most when a health situation forces a change at home.
The amount you can count is the cost of the improvement minus any increase in your home's value. When a modification adds no market value, which is common for accessibility work like wheelchair ramps, grab bars, support rails, or widened doorways, the full cost generally counts. When it does add value, you subtract that increase. The classic example from the tax guidance: an $8,000 home elevator installed on a doctor's advice raises the home's value by $4,400, so $3,600 counts as a deductible medical expense.
Two limits keep this honest. First, medical expenses are deductible only to the extent your total medical costs for the year top 7.5% of your adjusted gross income. If your AGI is $80,000, the first $6,000 of medical spending doesn't count, and only the amount above that does. Second, you have to itemize on Schedule A to claim it at all. Because of that floor, many families bunch a stairlift, a ramp, and a first-floor bathroom into a single year so the combined cost clears the threshold.
A few practical notes. Keep your doctor's recommendation showing the work was for medical care rather than comfort or style, since that documentation is what holds up if anyone asks. And you can't claim the same dollars twice. If you deduct part of a project as a medical expense, you can't also add that same amount to your home's basis later.
How You Finance the Work Changes the Tax Answer
Here's where my side of the business meets your tax return. Interest on a loan secured by your home is deductible only when you use the borrowed money to buy, build, or substantially improve the home that backs the loan. That single rule decides whether the interest on your home equity loan or line of credit helps you at tax time.
The use of the money is what matters, not the name on the loan. Pull from a home equity line to remodel the kitchen, and that interest can be deductible. Use the same line to buy a car, pay tuition, or wipe out credit card balances, and that interest is not deductible, even though it's the same loan. Split the money between a kitchen and a family vacation, and only the kitchen portion qualifies. Two more conditions apply: your combined home-loan debt has to stay within the $750,000 cap ($375,000 if married filing separately), and you have to itemize. Lawmakers recently made both the cap and this use-of-proceeds rule permanent, so it isn't set to expire.
A cash-out refinance works the same way. The slice of the new loan you spend to substantially improve the home can count toward deductible mortgage interest. The cash you take out for other purposes does not. At AmeriSave, a cash-out refinance and a home equity line are two of the common ways homeowners fund a renovation, and which one fits depends on your rate, your equity, and how you'd rather structure the payment. An AmeriSave loan officer can lay out the options and the tradeoffs so you can choose, rather than be sold.
Let me hand you a real lesson from the financing side, with the names left out. I once worked through a deal where a borrower took cash out for a project, then within a month realized the job needed more equity than they'd pulled. We had to slow the back end down and rework the loan before it ever reached servicing. The takeaway is simple: size the financing to the actual scope of the project, get a clear estimate before you close, and keep the invoices that show where every dollar went. The tax rule rewards money that goes into the home, and the only way to prove that is documentation that traces the loan proceeds to the work.
People ask why borrowers stick with AmeriSave for this type of financing, and my answer comes down to three things. A reputation built on customer satisfaction. Loan officers who are well trained and, in a lot of cases, deeply tenured. And the ability to get the transaction done quicker and at a lower cost than the alternatives. Those three pillars matter more on a renovation loan than people expect, because the paperwork and the timing are where these deals tend to wobble.
What Substantially Improving the Home Means for Your Interest Deduction
That word "substantially" does a lot of work in the tax rule, so it's worth pinning down. The same test that separates an improvement from a repair applies here: the work has to add value to the home, prolong its useful life, or adapt it to a new use. A kitchen remodel, a room addition, a new roof, or a systems upgrade clears that bar. Routine maintenance and cosmetic touch-ups generally don't, even when you pay for them with borrowed money.
Why does the distinction matter so much on the financing side? Because the interest deduction follows the dollars into the home, not the loan paperwork. If you borrow $60,000 and spend $45,000 on a qualifying addition and $15,000 on furniture and a trip, only the interest tied to the $45,000 is deductible. The lender doesn't sort that out for you, and the closing documents won't either. That's a job for your records and your tax preparer. When a borrower asks me how to keep it clean, I tell them to run the improvement spending through a clear paper trail and keep the personal spending separate, so the deductible share is easy to prove later. An AmeriSave loan officer can help you size a cash-out refinance or a home equity line to the part of the project that actually improves the home, which keeps that deductible portion clean from the start.
A Home Office or a Rental Flips the Math
Everything above assumes the home is purely personal. Once part of it earns income, the rules change, and "not deductible" can turn into "deductible" or "depreciable."
If you're self-employed and use part of your home regularly and exclusively as your principal place of business, improvements to that space can reduce your taxable income, usually through depreciation. You claim it with the home-office rules, either by tracking actual expenses or by using the simplified method. One hard limit trips people up: a W-2 employee who works from home cannot take the home-office deduction, even when the employer requires remote work. That door closed for employees and remains closed.
Rental property follows its own track. Improvements to a rental are capitalized and recovered through depreciation over time rather than deducted all at once, while genuine repairs to a rental are generally deductible in the year you make them. If you rent out part of your home or convert it later, a tax professional can help you split the personal and business sides correctly, because the two halves are taxed under different rules.
The Energy Credits Most Articles Still Mention Are Gone for New Projects
This is the part of the topic that's changed the most, and a lot of older articles, and more than a few contractor pitches, haven't caught up. For years, two federal credits put money back in homeowners' pockets for going greener. One covered energy-efficient improvements like insulation, exterior doors and windows, certain heating and cooling equipment, and home energy audits, worth up to $1,200 a year and up to $2,000 for qualifying heat pumps. The other covered clean-energy systems such as solar panels, wind, geothermal, and battery storage, generally at 30% of the cost.
Both of those federal credits have been repealed for newly installed projects under the recent tax law. A project placed in service after the law's cutoff no longer qualifies for the federal credit. In plain terms, if you're planning insulation, new windows, a heat pump, or a solar system now, don't count on a federal tax credit to help pay for it, because that window has closed.
There's one timing wrinkle worth raising with your preparer. If you completed and placed an energy project in service before the cutoff, the credit may still apply to that earlier tax year, even if you're only now filing for it. That's a conversation for your tax professional, who can confirm whether your installation date qualifies.
The federal door closing doesn't mean every incentive is gone. Many states run their own energy programs, lots of local utilities offer rebates on efficient equipment, and some manufacturers provide their own incentives. Before you write off the savings entirely, check with your utility and your state energy office. The federal credit was a nice bonus while it lasted, but the stronger case for most efficiency upgrades was always the lower monthly bill, and that benefit shows up every month regardless of the tax code.
Will You Even Benefit? The Standard-Deduction Reality
Here's a reality check that saves people a lot of false hope. The deductions for mortgage interest and medical modifications only help if you itemize, and itemizing only pays off when your itemized total beats the standard deduction. That standard deduction now runs $16,100 for a single filer, $32,200 for a married couple filing jointly, and $24,150 for a head of household. Those are large numbers, and the great majority of taxpayers, roughly nine in ten, simply take the standard deduction and move on.
What that means in practice is straightforward. A few thousand dollars of mortgage interest and a modest medical modification often won't clear that bar by themselves, especially later in a loan when most of your payment is principal rather than interest. So before you bank on a write-off, add up what you'd actually itemize and compare it honestly against the standard amount. If you come up short, the deduction you were counting on simply doesn't show up on your return.
This is exactly why the cost-basis benefit is the quiet workhorse of this whole topic. It lowers your taxable gain when you sell whether or not you itemize, which makes it the one home-improvement tax break almost every owner can actually use. If the itemized math doesn't work for you this year, that's all the more reason to keep clean improvement records for the day you sell.
The Mistakes I See Most Often
After enough years around these conversations, the same handful of errors keep coming up. None of them are foolish. They come from reasonable assumptions about how taxes ought to work. Here are the ones worth steering around.
- Treating repairs like improvements. A repaint or a leak fix feels like money in the home, but it doesn't add to your basis and won't help at sale. Only work that adds value, extends the home's life, or adapts its use counts.
- Expecting a deduction the year you spend. Improving the home you live in is personal spending, so there's no current write-off. The benefit, when there is one, shows up later or through a specific door like a medical need or a home office.
- Counting on the energy credits. The two big federal credits for efficiency and clean-energy upgrades have been repealed for newly installed projects. Plenty of older articles and sales pitches haven't caught up, so don't let one talk you into a purchase that no longer carries a federal credit.
- Skipping the records. The deduction or the basis adjustment is only as good as your ability to prove it, so if there's no invoice and no proof of payment, there's no deduction when someone asks.
- Double-dipping on a medical project. If you deduct part of a modification as a medical expense, you can't also add those same dollars to your basis. Pick the bucket, because you don't get both for the same money.
- Assuming the loan name decides the deduction. It's the use of the proceeds that matters. Improvement dollars can carry deductible interest, while the cash you spend on a car or a credit-card payoff doesn't, even from the same home equity line.
If you're funding the work and want the deductible share to stay clean, an AmeriSave loan officer can help you structure the financing around the part of the project that actually improves the home.
Keeping Records the IRS Will Accept
Every benefit in this article shares one requirement, so it earns its own section. Records are the difference between a deduction that holds and one that gets thrown out. The tax rules reward the homeowner who can prove what they spent and why.
For improvements that add to basis, save itemized contractor invoices that describe the work, proof of payment such as bank or card statements and canceled checks, and any permits or inspection records. Hold those for as long as you own the home plus at least three years after you file the return reporting the sale. For a $120,000 run of improvements, that folder can shield tens of thousands of dollars of gain from tax. For medical modifications, add the doctor's recommendation and, if the work raised your home's value, an appraisal showing the change. For financed work, keep the loan documents and the invoices that tie the proceeds to the project, since the tax rule turns on tracing the money to the home.
You want to be comfortable that if anyone ever asks, the paper tells the whole story without you having to remember it. That's the standard I'd hold any borrower to, and it's the same standard the tax authorities apply.
Tax rules shift, and the energy credits are a fresh reminder that what's true one year can change the next. What doesn't shift is what's in your control: knowing which bucket your project falls in before you start, keeping clean records, and getting a tax professional's read before a major spend. If financing is part of the plan, an AmeriSave loan officer can help you structure it so the dollars that go into your home are documented the way the tax rules expect. A good CPA or enrolled agent earns their fee on exactly these questions, and the money they save you usually dwarfs what they charge.

Frequently Asked Questions
No, not in the year you pay for it. A kitchen remodel is a capital improvement, so instead of a current deduction it adds to your home's cost basis and can lower your taxable gain when you sell. For a single filer, the first $250,000 of gain ($500,000 for joint filers) is already excluded, so the basis boost matters most on larger gains or longer-held homes.
No, routine repairs on your personal residence aren't deductible, and they generally don't add to your basis either. Fixing a leak, patching drywall, or repainting keeps the home in shape but doesn't qualify. The exception is a repair that's folded into a larger qualifying improvement or that serves a rental or a qualifying home-office space.
Yes, the interest is deductible when you use the proceeds to buy, build, or substantially improve the home that secures the loan, as long as your total home-loan debt stays within the $750,000 cap ($375,000 if married filing separately) and you itemize. Use the same funds for a car or a credit-card payoff, and that portion's interest isn't deductible.
No, not for newly installed projects. The federal energy-efficient home improvement credit and the residential clean energy credit, once worth up to 30% of cost, were repealed for property placed in service after the law's cutoff. State programs, local utility rebates, and manufacturer incentives may still help, so check locally before assuming there's no savings.
You can deduct the cost that exceeds any increase in your home's value, and only the share of total medical expenses above 7.5% of your adjusted gross income, if you itemize. A ramp or grab bars that add no value are generally fully countable, while an $8,000 elevator that raises value by $4,400 yields a $3,600 medical expense.
Yes. The part of a cash-out refinance you spend to substantially improve the home can count toward deductible mortgage interest within the $750,000 limit, while the cash you take for other uses does not. Keep invoices that trace the proceeds to the project, because the deduction depends on showing where the money went.
Yes for mortgage interest and medical modifications, which both go on Schedule A and only help if your itemized total beats the standard deduction of $16,100 for single filers or $32,200 for joint filers. The cost-basis benefit at sale is the exception, since it lowers your taxable gain whether or not you itemize.
Yes, without question. Improvements that add to your cost basis can save you real money at sale, but only if you can prove them, so keep invoices and proof of payment for as long as you own the home plus at least three years after you sell. On a $120,000 run of improvements, that paperwork can keep tens of thousands of dollars of gain out of reach of the tax.
