How to start a tax file for the house

A calculator and pen on papersMove-in

Start one folder of homeowner tax records with your closing statement, each Form 1098, proof of property taxes paid, and receipts for improvements. You use the first three to see if itemizing beats the standard deduction each year. You use the last to reduce taxable gain when you sell. Keep it all while you own the home.

The two kinds of homeowner tax records

Think of this file as two records with different lifespans. The yearly record supports deductions for one tax return: mortgage interest, property taxes and any points. The lifetime record tracks your basis, which starts with what you paid for the house and grows when you make improvements. That second record may not matter for decades, then matter a lot in the year you sell.

When to start your homeowner tax records

Set it up right after closing, while your settlement statement is easy to find. Your first return as an owner needs figures from it. Lenders should send Form 1098 by January 31 if you paid $600 or more in mortgage interest during the year. After that, add improvement receipts when you pay them, since an invoice is hard to rebuild years later.

Homeowner tax deductions and limits to check each year

ItemAmountTax year
Standard deduction, married filing jointly$32,2002026
Standard deduction, single$16,1002026
State and local tax limit$40,400 ($40,000 for 2025)2026
Income where that limit starts to shrink$505,000 ($500,000 for 2025)2026
Mortgage debt for the interest deduction, loans after Dec. 15, 2017$750,0002025; check IRS Pub. 936 each year

If you're married filing separately, the state and local limit and the mortgage limit are half. A sample couple filing jointly for 2026 pays $18,000 in mortgage interest, $6,000 in property tax and $5,000 in state income tax. That adds up to $29,000, which is below $32,200, so the standard deduction wins and the interest brings no extra benefit. These limits change, so check them each year.

Records pay off at sale too. If you meet the ownership and use tests, you may exclude up to $250,000 of gain, or $500,000 on most joint returns. Improvements raise your basis and lower your gain.

How to build a folder of homeowner tax records

  1. Create the folder

    Make two sections: yearly tax papers, and home basis papers. Any format works if the records stay clear, accurate and available to the IRS.

  2. File your closing statement

    Mark the points, prorated property taxes and interest paid at closing. Also note fees that add to basis, such as recording fees, transfer taxes and owner's title insurance.

  3. Save each Form 1098

    Download it from your servicer in January and check the interest and points against your own records.

  4. Capture property taxes paid

    Use your year-end escrow statement or county receipt. Keep the amount paid, not the amount you deposited.

  5. Start an improvement log

    Use columns for date, project, contractor, cost and permit number. Attach the invoice and proof of payment.

  6. Sort improvements from repairs

    An addition, a whole new roof, central air, a paved driveway or new wiring raises basis. Repainting, fixing leaks and replacing a broken pane generally don't.

  7. Compare once a year

    Add your itemized deductions and compare them with the standard deduction, or ask your preparer to run it both ways.

How homeowner tax deductions vary by state

The figures here are federal. Your state may treat mortgage interest and property tax differently, and some offer their own credits or exemptions for a main home. Local rules also decide when property tax is billed, which affects how much you actually paid in a given year. Check your state revenue department or ask your preparer.

Mortgage interest deduction and other homeowner tax traps

  • Escrow deposits aren't the deduction. Only tax the servicer actually paid to the taxing authority counts.
  • Closing year splits. You and the seller each deduct property tax by days owned. The IRS example: 122 days of a $730 tax bill gives a $244 deduction.
  • Interest paid at closing may be missing from Form 1098. If so, the IRS tells you to add it and attach an explanation.
  • Points have tests. Purchase points can usually be deducted in the year paid only if conditions are met, including that the funds you brought to closing, plus any seller-paid points, at least equal them.
  • Non-deductible items. Homeowners insurance, HOA fees, principal, utilities and repairs don't qualify.
  • Mortgage insurance. It wasn't deductible for 2025, but the IRS says the election is permanent for 2026 onward. Ask your preparer about income limits.

What homeowners say about keeping tax records

What owners say

Don't buy based on the mortgage-interest deduction alone. Owners note that with today's larger standard deduction, many households get little or no tax benefit from interest and property tax. (Hacker News)

Where owners disagree: Owners point out that since the standard deduction went up, many households get little benefit from mortgage interest and property tax. Don't count on it when budgeting. (Hacker News)

Home improvement receipts and other tax questions

Can I deduct home repairs on my taxes?

Generally no. Repairs on your personal home aren't deductible and generally don't add to basis. Repairs done as part of a larger remodel can count as part of the improvement, so keep those invoices.

Is homeowners insurance tax deductible?

No, not for a home you live in. The IRS lists homeowners and fire insurance among items you can't deduct.

How long should I keep home improvement receipts?

Keep them while you own the home and for the limitations period after you sell it, which is generally 3 years from filing. A replacement home can stretch that further.
