Can I deduct home improvements on my annual tax return?

No, you cannot deduct home improvements on your annual Form 1040 in the year you pay for them. Instead, you add them to your home's Adjusted Cost Basis, which reduces your taxable capital gains when you sell the home.

What home renovations qualify to increase tax basis under IRS Pub 523?

Capital improvements with a useful life of more than 1 year qualify: kitchen/bathroom remodels, room additions, new roofs, HVAC replacements, electrical upgrades, decks, fences, and solar installations. Routine repairs like painting or fixing leaks do not qualify.

What You Need to Do During Tax Filings:

1. During Years You Own & Remodel the Home (Form 1040):
You do NOT report home improvements on your annual Form 1040 while living in the home. There is no annual tax write-off. Instead, you must save all invoices, contractor receipts, and canceled checks in a digital tax vault.

2. In the Year You Sell the Home (Form 8949 & Schedule D):
Report the sale on IRS Form 8949 (Sales and Dispositions of Capital Assets) Part II. Enter your gross sales proceeds in Column (d), your Total Stepped-Up Adjusted Basis (Purchase + All Improvements) in Column (e), and Code H in Column (f) to claim your $250k / $500k Section 121 exclusion.

Primary Home Improvements & IRS Capital Gains FAQ

Key rules under IRS Publication 523 on tracking cost basis for homeowners.

What counts as a "Capital Improvement"?

Under IRS Pub 523, a capital improvement must add to the value of your home, prolong its useful life, or adapt it to new uses with a lifespan of more than 1 year (e.g. remodeling a kitchen, new roof, HVAC system, adding a deck, room addition).

What does NOT count (Repairs vs Improvements)?

Routine maintenance and repairs do NOT increase your basis. Painting walls, fixing leaks, repairing broken gutters, or replacing a broken window pane are considered maintenance and cannot be added to your cost basis.

What receipts should I keep?

Keep contractor agreements, invoices, material receipts, proof of payment (bank statements or canceled checks), and permit approvals for at least 3 years after the tax return on which you report the sale of the home.
