Which Home Improvement Receipts to Keep (Taxes and Resale)

Keep receipts for capital improvements — work that adds value, extends the home's life, or adapts it to new uses. These raise your cost basis and can reduce the taxable gain when you sell. You generally do not need to keep receipts for routine repairs, which don't affect basis. Hold improvement receipts for at least three years after you sell the home. Keep them longer if the paperwork also supports a warranty.

This article is general information, not tax or financial advice. Tax rules change and depend on your situation. Confirm anything here with a tax professional before you act on it.

Here's how to tell an improvement from a repair, why the difference matters at sale, and how long to hold each.

Capital improvements vs. repairs

The distinction drives everything. In broad terms:

• A capital improvement adds value, prolongs the home's useful life, or adapts it to a new use. Think a new roof, a room addition, a remodeled kitchen, a new HVAC system, or a finished basement.
• A repair keeps the home in ordinary working condition without materially adding value or life. Think fixing a leak, patching drywall, or replacing a broken window pane.

The line can blur. Replacing a few shingles is a repair; replacing the whole roof is an improvement. Painting one room is a repair; a full renovation that includes painting rolls the paint into the improvement. When work is part of a larger upgrade, it usually counts toward the improvement.

Keep the improvement receipts. The repair receipts are useful for warranty and resale proof, but they don't change your tax basis.

Why cost basis matters at sale

Your cost basis is, roughly, what you paid for the home plus the capital improvements you made over the years. When you sell, your gain is the sale price minus selling costs minus your basis. A higher basis means a smaller gain.

Here's a simplified illustration:

Many homeowners qualify for a capital-gains exclusion on a primary residence, which covers a large chunk of gain for many sellers. But that exclusion has limits, and it doesn't apply the same way to second homes, rentals, or very large gains. When the gain exceeds the exclusion, every documented dollar of improvement reduces what's taxable. The homeowner who kept receipts pays less. The one who didn't loses the deduction they were entitled to. Again — confirm your own exclusion and eligibility with a tax professional.

What counts as an improvement (examples)

A working list of items that generally qualify as capital improvements:

• Additions: rooms, decks, garages, porches
• New roof, siding, or windows
• New HVAC, furnace, water heater, or central air
• Kitchen or bathroom remodels
• Finished basement or attic
• New flooring throughout
• Plumbing or electrical system upgrades
• Fences, driveways, retaining walls, landscaping that adds value
• Insulation, storm windows, security systems

And items that are generally repairs, not improvements:

• Fixing leaks, patching, repainting a room
• Replacing broken glass or a single fixture
• Servicing or minor part replacement on existing systems

What to keep with each receipt

A receipt alone is often not enough. For each improvement, keep:

• The receipt or invoice showing what was done and what it cost
• The contract for larger jobs
• Proof of payment — a canceled check, card statement, or bank record
• Before-and-after photos where useful
• The permit if the work required one

Store these together, one folder per project. When the work is also under warranty, the same paperwork does double duty. Keeping it alongside the rest of your home documents means you're not hunting for it years later.

How long to keep them

The safe default is to keep improvement receipts for at least three years after you sell the home, because that's a common window for tax review of the sale year. Some situations warrant longer. Because the improvements you made in year two affect the basis you report in year twenty, these are records you carry for the life of your ownership and a few years past the sale.

Routine repair receipts can go after about three years. They're most useful for warranty follow-up and as proof of upkeep when selling, which is part of the paperwork buyers expect — see the documents you need when selling your house.

How to organize improvement records

The receipts only help if you can produce them years later. A simple system:

• One folder per project. Group everything for a job — the deck, the re-roof, the kitchen — in a single place: contract, receipts, proof of payment, permit, photos.
• Name files by date and project. 2024-06 Deck build - contract.pdf sorts and searches far better than a scanner's default filename.
• Record a running total. A one-line summary per project — date, description, cost — becomes your improvement ledger. At sale, this is the list that supports your cost basis.
• Scan and back up. Paper fades and gets lost over a decade of ownership. A scanned copy in the cloud or an app survives.

Do this at the time of the work and the record assembles itself. Reconstruct it at closing and you'll be guessing at numbers and hunting for receipts you may have thrown away.

A worked example of the ledger

Here's what a decade of tracked improvements might look like as a simple ledger:

That total is added to what you paid for the home. Without the ledger and the receipts behind it, that $84,500 is invisible at sale, and your reported gain — and potential tax — is higher than it needs to be. The ledger is the difference between claiming what you're entitled to and losing it to poor record-keeping.

The failure mode

The classic mistake is realizing at closing that you spent tens of thousands improving the home over a decade and can document almost none of it. The new HVAC, the kitchen, the deck — all real, all undocumented, all lost from your basis. The fix costs nothing but a habit: save the receipt when the work is done, file it under the project, and note it in your records the same week.

Where Huswerks fits

Huswerks keeps improvement receipts where they belong — attached to the project they paid for, tagged to the property, and exportable when tax time or a sale arrives. Log the cost, attach the receipt and photos, and it's stored for as long as you own the home. When you sell, the record of what you invested is already assembled.

FAQ

Which home improvement receipts should I keep for taxes? Keep receipts for capital improvements — work that adds value, extends the home's life, or adapts it to a new use. These raise your cost basis. Routine repair receipts don't affect basis but are useful for warranty and resale.

How long should I keep home improvement receipts? At least three years after you sell the home, since improvements from any year of ownership affect the basis you report at sale. Some situations warrant keeping them longer.

What's the difference between a repair and a capital improvement? A repair keeps the home in ordinary working condition; an improvement adds value, prolongs its life, or adapts it to new uses. When a repair is part of a larger upgrade, it usually counts as part of the improvement.

Do improvement receipts really lower my taxes at sale? They raise your cost basis, which reduces your taxable gain. Many sellers are covered by the primary-residence exclusion, but when the gain exceeds it, documented improvements reduce what's taxable. Confirm your eligibility with a tax professional.

What should I keep besides the receipt? The contract, proof of payment, permits, and before-and-after photos where relevant. Together they substantiate the improvement if the sale is ever reviewed.
