What the IRS counts as a deductible home improvement
The IRS allows you to deduct home improvements only if they add value to your home, prolong its life, or adapt it to a new use — and only when you sell the house. You cannot deduct them as a current-year expense on your tax return. Instead, you add the cost to your home's basis (what you paid for it originally), which reduces your taxable gain when you eventually sell.
Repairs and maintenance do not may have access to. Fixing a leaky roof or repainting a wall counts as upkeep, not improvement. The difference: an improvement changes the property itself; a repair restores it to its former condition. A new roof is deductible. Patching the old one is not.
You must have receipts and documentation showing what was done, who did it, and what you paid. The contractor's invoice should describe the work clearly enough that the IRS can understand whether it was an improvement or a repair.
Key Takeaways
- Home improvements reduce your taxable gain when you sell, but you cannot deduct them as a current expense — you add the cost to your home's basis instead.
- Repairs and routine maintenance are never deductible; only work that adds value, extends the home's life, or adapts it to a new use counts as an improvement.
- Common deductible improvements include new roofs, HVAC systems, kitchens, bathrooms, insulation, windows, and structural additions like decks or rooms.
- Keep all receipts and contractor invoices that describe the work performed, because the IRS may ask for proof that the expense was an improvement, not a repair.
- The $250,000 exclusion on home sale gains ($500,000 for married couples) means many homeowners owe no tax on their profit even without improvements.
Improvements that clearly may have access to for deduction
A new roof qualifies because it extends the life of the home. Replacing the entire roof system — not patching a few shingles — is an improvement. The same applies to a new HVAC system, new electrical wiring, new plumbing, or new foundation work.
Kitchen and bathroom remodels almost always may have access to, because they add significant value and involve structural or system changes. A new kitchen includes cabinets, countertops, appliances, flooring, and plumbing. A bathroom remodel includes fixtures, tile, plumbing, and sometimes structural changes.
Additions to the home — a new bedroom, bathroom, deck, porch, garage, or finished basement — are improvements because they increase the square footage or usable space. Landscaping that is permanent, such as a retaining wall or irrigation system, may may have access to, though ornamental plants typically do not.
Energy-efficient upgrades like new insulation, new windows, a heat pump, or solar panels count as improvements. These extend the home's life or adapt it to new use. Painting the exterior or interior is generally considered maintenance, not an improvement, unless it is part of a larger project.
Work that does not count as deductible
Repairs restore a home to working order without adding value. Patching drywall, repainting, fixing a leaky faucet, replacing broken windows, or sealing cracks are repairs. Replacing a few shingles on an otherwise sound roof is a repair. Replacing the entire roof is an improvement.
Routine maintenance — cleaning gutters, servicing the HVAC system, power-washing the deck — is never deductible. Lawn care and ornamental landscaping do not count. Replacing a single appliance, such as a refrigerator or dishwasher, is typically a repair or replacement of a worn item, not an improvement, unless it is part of a full kitchen remodel.
Cosmetic changes that do not add structural value are repairs. New paint, new carpet, or new flooring in a single room without other changes usually falls into this category. However, if you replace all flooring throughout the home as part of a comprehensive renovation, it may may have access to as an improvement.
How to document improvements for the IRS
Keep the original contractor invoice or receipt for every improvement. The document should show the date, the contractor's name and address, a description of the work performed, the materials used, and the total cost. If the invoice is vague — for example, "home renovation $15,000" — ask the contractor for an itemized breakdown.
Photograph the work before, during, and after completion. These images help prove that the work was done and what it involved. Store photos with your receipts.
If you did the work yourself, keep receipts for all materials purchased. Write down the dates you worked and the hours spent. The IRS will not reimburse you for your own labor, but material costs still count toward the improvement's basis.
Create a file for your home that includes the original purchase deed, the purchase price, all improvement receipts, and a running total of improvements made. When you sell the home, provide this file to your tax preparer or accountant. They will use it to calculate your adjusted basis and your taxable gain.
The home sale exclusion and when improvements matter most
The IRS allows you to exclude up to $250,000 of gain from the sale of your home if you are single, or $500,000 if you are married filing jointly — provided you owned and lived in the home for at least two of the last five years. This exclusion applies whether or not you made improvements.
For many homeowners, this exclusion means they owe no federal tax on their home sale profit at all. If you bought your home for $300,000, made $50,000 in improvements, and sold it for $500,000, your gain is $150,000 ($500,000 sale price minus $350,000 adjusted basis). If you are single, the entire $150,000 is excluded, and you owe no tax.
Improvements matter most when your gain exceeds the exclusion. If your gain is $600,000 (single) or $750,000 (married), the excess is taxable. In that case, every dollar of documented improvements reduces the taxable portion. Improvements also matter if you are selling a rental property or a second home, which do not may have access to for the exclusion.
State and local tax treatment of home improvements
Most states follow the federal rule: improvements reduce your taxable gain when you sell, but are not deductible as a current expense. A few states have their own rules or exemptions. California, for example, does not tax capital gains on primary residences in the same way federal law does, but the exclusion rules are similar.
Some states offer property tax breaks for energy-efficient improvements or historic preservation work. These are separate from income tax deductions and vary widely by state. Check your state's tax authority website or ask your accountant whether your state offers any credits or exemptions for the improvements you made.
Local property taxes may increase after you make major improvements, because the assessed value of your home may rise. This is not a deduction issue — it is a property tax issue — but it is worth understanding before you undertake expensive work.
Frequently Asked Questions
Can I deduct home improvements on my tax return the year I make them?
No. Home improvements are not deductible as a current expense. Instead, you add the cost to your home's basis, which reduces your taxable gain when you sell. The deduction happens at sale time, not when the work is done.
Is a new kitchen always deductible?
Yes, a full kitchen remodel is always deductible because it adds value and involves structural or system changes. Replacing a single appliance, such as a refrigerator, is typically a repair, not an improvement, unless it is part of a larger kitchen renovation.
What is the difference between a repair and an improvement?
A repair restores something to working order without adding value — patching a roof, fixing a leak, or repainting. An improvement adds value, extends the home's life, or adapts it to a new use — replacing an entire roof, adding a room, or upgrading to new HVAC. When in doubt, ask your contractor to describe the work in writing.
Do I have to report home improvements when I sell?
You should provide your tax preparer with all improvement receipts so they can calculate your adjusted basis correctly. The IRS may ask for documentation if your reported gain seems unusually low compared to the sale price. Keeping organized records protects you if questions arise.
What if I cannot find receipts for improvements made years ago?
Gather whatever documentation you have — old bank statements, credit card statements, cancelled checks, or contractor business records. If you truly cannot locate receipts, you may be able to reconstruct the cost using photographs and your own written records of the work. Consult a tax professional about what the IRS will accept in your situation.
