Home improvements typically don't provide a direct tax deduction in the year they're made.
However, qualifying improvements increase your home's adjusted cost basis, which reduces your taxable capital gain when you sell.
When you sell your home for more than you paid (plus improvements), the profit (capital gain) is taxed unless it falls within the home sale exclusion ($250,000 single / $500,000 MFJ for qualifying primary residences).
The higher your basis, the smaller your taxable gain. Sellers should also understand how closing costs when selling similarly reduce the amount realized, and how closing costs when buying added to their original basis.
Is Home Improvements When Selling Tax Deductible?
Qualifying home improvements that increase your adjusted basis include: room additions, kitchen remodel, bathroom remodel, new roofing, HVAC systems, windows and doors, landscaping, swimming pools, new flooring, electrical rewiring, plumbing upgrades, insulation, and structural improvements.
These add to your cost basis and reduce the eventual taxable gain when you sell.
Each of these qualifies because it adds value to the property, prolongs its useful life, or adapts it to new uses — all three categories recognized by the IRS.
Requirements and Conditions
Not all home costs qualify as improvements — repairs (patching a hole, fixing a leak) maintain the property but don't increase basis.
Improvements must add value, prolong the property's useful life, or adapt it to new uses.
Keep receipts and records of all capital improvements throughout your homeownership — particularly important if your gain might exceed the $250,000/$500,000 exclusion.
Your basis also includes deductible closing costs paid at purchase (including mortgage points and prepaid taxes).
Together, improvements and purchase-side closing costs build your adjusted basis over time.
If you're also interested in direct deductions, see which home improvements are tax deductible in the year made — energy credits are available for some of these same projects.
Important Limitations
For a $400,000 purchase with $80,000 in qualifying improvements, your adjusted basis is $480,000.
If you sell for $750,000, your gain is $270,000 — above the $250,000 single-filer exclusion by $20,000, incurring capital gains tax on $20,000 only.
Without the improvements, your gain would have been $350,000 and the taxable amount $100,000.
Also remember that home renovation deductibility is closely related — understanding the difference between a deductible repair and a basis-increasing improvement matters throughout your ownership.
At sale time, coordinating with a licensed real estate agent and a tax professional ensures you're capturing every eligible cost in your gain calculation.
Frequently Asked Questions
Can you deduct home improvements when selling?
Qualifying home improvements that increase your adjusted basis include: room additions, kitchen remodels, bathroom remodels, new roofing, HVAC systems, windows and doors, landscaping, swimming pools, new flooring, electrical rewiring, plumbing upgrades, insulation, and structural improvements.
These add to your cost basis and reduce the eventual taxable gain when you sell.
Do I need to itemize to claim this deduction?
Yes — most personal expense deductions require itemizing on Schedule A (Form 1040).
You itemize only if your total itemized deductions exceed the standard deduction ($14,600 for single/$29,200 for married filing jointly in 2026 tax year).
Home improvement basis adjustments are NOT itemized deductions — they reduce your capital gains calculation on Form 8949 and Schedule D when you sell.
What is the standard deduction for 2026?
The 2026 standard deduction is $14,600 for single filers and $29,200 for married filing jointly. Most taxpayers benefit more from the standard deduction than itemizing. The capital gains benefits from documenting home improvements are entirely separate from this calculation.
Where do I report this deduction?
Home sale gain is reported on Form 8949 and Schedule D (Capital Gains and Losses). Your adjusted basis — which includes all capital improvements — is used to calculate the gain. Most personal itemized deductions are reported on Schedule A.
Business deductions go on Schedule C or the appropriate business form.
Should I itemize or take the standard deduction?
Itemize only if your total deductible expenses (mortgage interest, SALT, charitable gifts, medical expenses, etc.) exceed the standard deduction.
For most taxpayers, the standard deduction is larger.
The capital gains benefit of documenting home renovations is independent of how you file — every documented improvement reduces your taxable gain at sale.
