Home Improvement Records: Why Keep Them for Taxes

Keeping home improvement records is one of the simplest ways to cut the tax you owe when you sell your house. Every qualifying improvement adds to your home’s cost basis. A higher basis means a smaller taxable gain. Without receipts, invoices, and proof of payment, you cannot claim those costs, and you may pay capital gains tax on money you already spent.

Many homeowners skip the paperwork because of the home sale exclusion. That rule lets you exclude up to $250,000 of gain, or $500,000 on a joint return. Congress set those limits in 1997 and has never adjusted them for inflation. Home prices have climbed a long way since then, so more sellers now cross the line. Nexus United Inc. sees it every filing season. A long time owner sells, the gain passes the exclusion, and the receipts that would have lowered the tax are gone.

Home Improvement Records and Taxes: Key Facts for 2026

How Home Improvement Records Lower Your Tax Bill

The IRS taxes your gain, not your sale price. Gain is what you receive from the sale minus your adjusted basis. Three steps get you there.

1. Amount realized. Selling price minus selling costs such as agent commissions, title fees, and legal fees.
2. Adjusted basis. Purchase price, plus certain closing costs from when you bought, plus the cost of improvements. Then subtract depreciation, insurance payouts for casualty losses, and energy credits you claimed.
3. Gain. Amount realized minus adjusted basis.

Improvements are the part most owners lose track of. The purchase price sits on your closing statement. The new roof from 2011 and the kitchen remodel from 2018 only exist on paper if you saved the paper. The IRS expects you to prove every dollar you add to basis. The same rule applies to stocks and funds, which is why tracking your investment basis matters as well.

The Home Sale Exclusion in 2026

Section 121 of the tax code allows the exclusion on the sale of your main home. It does not cover a vacation home or a rental. To claim the full amount you must pass three tests.

• Ownership. You owned the home for at least 24 months of the last 5 years.
• Residence. You lived in it as your main home for at least 24 months of the last 5 years. The months do not need to be in a row.
• Look back. You did not exclude gain on another home sale in the prior 2 years.

On a joint return, only one spouse needs to meet the ownership test. Both must meet the residence test to get the full $500,000.

Two bills in Congress would change these limits. The More Homes on the Market Act would double them and index them to inflation. The No Tax on Home Sales Act would remove the cap. As of October 2026, neither has become law. Plan around the current $250,000 and $500,000 figures, and keep your records so you are covered either way.

What Missing Records Cost: A Worked Example

A married couple bought a home in 2001 for $300,000. Over 25 years they added a second story, a new roof, a pool, and a remodeled kitchen for $140,000 in total. They sell in 2026 for $1,150,000 and pay $60,000 in selling costs.

The missing paperwork costs this couple $21,000 at the 15 percent rate. If the 3.8 percent net investment income tax also applies, the cost rises to $26,320. A folder of receipts would have prevented all of it.

10 Situations Where Home Improvement Records Save Taxes

The exclusion covers many sales in full. These are the cases where it falls short, and where your records carry real dollar value.

1. You have owned the home for a long time. Decades of appreciation can push the gain past $250,000 or $500,000. Improvements may be the only thing that brings it back under.
2. You convert the home to a rental. Depreciation starts from your basis, so you need the purchase cost and every improvement to set it. When you sell, the depreciation you took is taxed at up to 25 percent.
3. The home becomes a second home. A vacation home does not qualify as a main home. Time it was not your main residence after 2008 can also reduce the exclusion.
4. You sell before two years. You get no exclusion, or a reduced one if you moved for work, health, or an unforeseen event. A reduced exclusion leaves more gain exposed.
5. You divorce and one spouse keeps the home. That spouse can exclude only $250,000 on a later sale as a single filer.
6. Your spouse passes away. You keep the $500,000 limit only if you sell within two years of the death and have not remarried. After that it drops to $250,000.
7. You suffer a casualty loss. A hurricane, flood, or fire changes your basis. Insurance payments reduce it. The cost of restoring the home adds to it. Florida owners face this more often than most.
8. You use part of the home for business or rent a separate unit. Depreciation claimed after May 6, 1997 cannot be excluded. A separate rental unit needs its own gain calculation.
9. You received the home as a gift. You generally take over the giver’s basis, so you need their purchase and improvement records too.
10. Congress changes the law. The limits could rise, fall, or be restructured. Good records protect you under any version.

Inherited homes work differently. The basis usually resets to the home’s value on the date of death, so earlier improvements no longer matter. Improvements you make after you inherit do count. If you want to control how a home passes to your heirs, read our guide on whether a living trust is right for you.

What Counts as a Home Improvement for Tax Purposes

The IRS draws a line between improvements and repairs. An improvement adds value to your home, extends its useful life, or adapts it to a new use. A repair only keeps the home in working order. IRS Publication 523 lists examples of both.

Three details catch people out.

• Repairs inside a remodel count. Painting on its own is a repair. Painting done as part of a full kitchen remodel becomes part of the improvement.
• Replaced improvements drop out. If you installed carpet in 2010 and replaced it in 2022, only the 2022 cost stays in your basis.
• Your own labor is worth zero. Materials you bought count. The hours you worked do not.

Some closing costs from your purchase also add to basis. These include title insurance, recording fees, survey fees, transfer taxes, and legal fees. Loan costs such as points, appraisal fees, and mortgage insurance do not. They may matter for other reasons, such as your home mortgage interest deduction. Special assessments for local improvements like sidewalks and sewer lines add to basis as well.

Energy Credits and Other Items That Reduce Your Basis

Basis moves down as well as up. You must subtract:

• Energy credits you claimed for solar panels, heat pumps, windows, doors, or insulation
• Utility subsidies you received for energy saving upgrades
• Depreciation you took or could have taken for a home office or rental use
• Insurance payments for casualty losses, and casualty losses you deducted
• Gain you postponed from a home sold before May 7, 1997

The two federal home energy credits ended for work completed after December 31, 2025. If you claimed either credit in earlier years, keep the Form 5695 from those returns with your improvement file. You will need the amounts when you sell. Our guide on how to get a bigger tax refund lists which credits ended and which deductions replaced them.

Which Home Improvement Records to Keep

You do not need the receipt for every can of paint or torn window screen. Those are repairs and would not count anyway. Keep records for anything that qualifies as an improvement, along with proof that you paid.

From the purchase

• Closing disclosure or settlement statement
• Purchase contract and deed
• Title insurance, survey, and recording fee receipts

For each improvement

• Signed contract or written estimate
• Itemized invoice showing the work, the date, and the address
• Proof of payment, such as a canceled check, card statement, or bank record
• Building permits and final inspection reports
• Before and after photos with dates
• Receipts for materials if you did the work yourself

For adjustments

• Form 5695 for any energy credits claimed
• Insurance claim paperwork and settlement letters
• Depreciation schedules from returns with a home office or rental use
• Form 2119 if you rolled over gain from a home sold before May 7, 1997

How Long to Keep Home Improvement Records

Keep them for as long as you own the home, then for at least three years after you file the return that reports the sale. That three year window is the standard period the IRS has to examine a return. It stretches to six years if a return leaves out more than 25 percent of the income it should show. See our guide on how long the IRS can audit you for the full timeline.

If you turned the home into a rental, keep the records until three years after you sell the rental. The basis follows the property the whole way.

How to Organize Your Records in 5 Steps

1. Open one basis file. Use a single folder, paper or digital, for the life of the home.
2. Scan receipts the day you get them. Thermal paper fades within a few years. A phone scan lasts.
3. Keep a running log. A simple spreadsheet with date, project, contractor, cost, and payment method is enough.
4. Back it up. Store one copy in the cloud and one outside the home, so a fire or storm cannot destroy both.
5. Review it each year. Add new projects at tax time, and remove any improvement you have since replaced.

Business owners will recognize the habit. It is the same discipline behind sound bookkeeping practices, applied to your largest personal asset.

What to Do If You Lost Your Receipts

You can often rebuild the file. Start now, well before a sale.

• Ask your city or county for copies of building permits
• Ask contractors for duplicate invoices
• Pull bank and card statements for the payment dates
• Check your lender’s files if you financed the work
• Gather dated photos, appraisals, and old listing sheets that show the changes

A reconstructed file is weaker than original receipts, but it is far better than nothing. The IRS can disallow any cost you cannot support. If your return is ever questioned, our guide on how to prepare for an IRS audit explains what examiners ask for.

Reporting the Sale and Paying the Tax

The closing agent may send you and the IRS a Form 1099-S showing the sale proceeds. If you receive one, report the sale on Form 8949 and Schedule D, even when the full gain is excluded. Skipping it is a common reason sellers get an IRS CP2000 letter a year or two later.

Gain above the exclusion is taxed at long term capital gains rates if you owned the home more than one year.

The 3.8 percent net investment income tax can apply on top when modified adjusted gross income passes $200,000 for single filers or $250,000 for joint filers. A large gain can also create an underpayment penalty, so you may need to make estimated quarterly tax payments in the year of sale. Florida has no state income tax, so Florida sellers deal with the federal bill only. If you relocate after the sale, check the rules on filing taxes after moving to a new state.

Frequently Asked Questions

Do I need to keep receipts for home improvements?

Yes. Receipts and proof of payment are how you prove the cost of improvements that raise your basis. If your gain is larger than the exclusion, each documented dollar lowers the amount that is taxed.

How long should I keep home improvement records?

Keep them for as long as you own the home, plus at least three years after you file the tax return for the year you sell. Six years is safer if the sale involves a large gain.

Which home improvements increase the cost basis of a home?

Improvements that add value, extend the home’s life, or adapt it to a new use. Examples include additions, a new roof, a remodeled kitchen, central air, new flooring, a pool, a fence, and a new driveway.

Are home improvements tax deductible?

Not on a personal residence. Improvements are added to your basis and reduce your gain when you sell. They are not among the tax deductions you claim each year.

Can I add the value of my own labor to my basis?

No. You can add the cost of materials and what you paid others. The IRS does not let you count your own time.

Does a new roof count as a home improvement?

Yes. A full roof replacement is an improvement and adds to basis. Patching a leak is a repair and does not.

Do I have to report my home sale to the IRS?

You must report it if you receive Form 1099-S or if any part of the gain is taxable. You can skip reporting only when the whole gain is excluded and no 1099-S was issued.

Has the home sale exclusion changed for 2026?

No. It is still $250,000 for single filers and $500,000 for joint filers. Bills to raise or remove the cap have been introduced in Congress, but none had passed as of October 2026.

What if I already filed and forgot to include my improvements?

You can generally file an amended tax return within three years of the original filing date. Adding documented improvements can lower the gain and produce a refund.
