What Documents Do I Need for Taxes If I Sold a House?

To file your taxes after selling a house, you need the closing documents from the sale, the closing documents from when you bought the home, receipts for every capital improvement you made during ownership, depreciation records if you ever rented the property or claimed a home office, proof the home was your primary residence, and the IRS forms that fit your situation. These are the documents needed for taxes when you sold a house, and missing any one of them can turn money you actually spent into money the IRS treats as profit.

Closing Documents From the Sale

Start with the Closing Disclosure from the sale, or the HUD-1 Settlement Statement if the transaction closed before October 2015.¹ This single document shows the sale price, every fee the closing agent charged you, and the net amount you received.

It is also the source for the selling expenses that reduce your taxable gain. You can subtract real estate commissions, advertising costs, legal fees, transfer taxes paid by the seller, and any loan charges you covered that would normally fall on the buyer.² Prorated property taxes and homeowner association dues are not selling expenses, so don’t lump them in.

You may also receive Form 1099-S, Proceeds From Real Estate Transactions. The closing agent files this with the IRS to report your gross proceeds. The agent can skip filing the form if you sign a written statement, under penalty of perjury, confirming the home was your principal residence, the full gain is excludable under Section 121, and the sale price is $250,000 or less ($500,000 if married).³ If you did receive a 1099-S, keep it. You must report the sale on your return even if the entire gain is excludable.⁴

Documents That Establish Your Original Basis

Your basis is what the IRS treats as your investment in the property. The higher it is, the smaller your gain. For a straightforward purchase, the original Closing Disclosure or HUD-1 is the foundational document: it records the purchase price and itemizes acquisition costs that get added to basis, including title insurance, appraisal fees, recording fees, and legal fees tied to the purchase. The purchase contract and recorded deed serve as backup, confirming the acquisition date and transfer of ownership.

If you came by the house some other way, the paperwork changes.

Inherited Property

If you inherited the home, the price the previous owner paid is irrelevant. Federal law resets the basis to the property’s fair market value on the date of death.⁵ To document this stepped-up basis, you need either a professional appraisal conducted close to the date of death or a copy of the federal estate tax return (Form 706) if one was filed.⁶ Most estates don’t owe estate tax and never file Form 706, so an appraisal is usually the safer document to have. If none was done at the time, a retrospective valuation from a qualified appraiser can sometimes fill the gap, though it is more expensive and less reliable.

Gifted Property

When you receive a home as a gift, you generally take over the donor’s basis.⁷ That means you need the donor’s original purchase documents and records of any improvements they made while they owned it. If the fair market value at the time of the gift was less than the donor’s basis, you’ll need documentation of both numbers, because you use the lower value for calculating a loss and the donor’s basis for calculating a gain.⁸ If the donor paid gift tax on the transfer, keep a copy of their gift tax return (Form 709); a portion of the tax may add to your basis.⁹

Property Received in a Divorce

A home transferred between spouses as part of a divorce is treated similarly to a gift for basis purposes. The receiving spouse takes the other spouse’s adjusted basis, including improvements made during the marriage. Gather the original purchase closing statement, all improvement records, and a copy of the divorce decree or property settlement agreement showing the transfer terms.

Receipts for Capital Improvements

Capital improvement records are the single biggest opportunity most sellers have to reduce their taxable gain, and they are the records people most often cannot find. Every qualifying improvement you made during ownership gets added to your basis.

The IRS draws a line between improvements and repairs. Improvements add value, extend the home’s useful life, or adapt it to a new use. Repairs just keep things running. A $15,000 kitchen remodel increases your basis; repainting the kitchen does not.² Common improvements that count include:

Additions such as bedrooms, bathrooms, decks, garages, and porches
Systems work: heating, central air, wiring, security systems, water filtration
Exterior work: new roof, new siding, storm or replacement windows
Grounds: landscaping, driveways, fences, retaining walls, swimming pools
Interior work: kitchen modernization, new flooring, built-in appliances, fireplaces

Repairs done as part of a larger renovation count as improvements. Replacing a few broken windowpanes is a repair; replacing those same panes as part of a whole-house window replacement makes the entire cost an improvement.²

For each project, keep the itemized invoice or receipt describing the work, the contractor agreement if there was one, and proof of payment such as a canceled check or bank statement. Specifics matter. “Installation of 200-amp electrical panel” is useful; “electrical work” is not. If you can’t document an improvement, the IRS won’t let you add it to your basis, and the money you spent gets taxed as if it were profit.

Depreciation Records if You Rented or Used a Home Office

If you rented out the home or any part of it, or claimed a home office deduction using the regular method, you have an extra documentation requirement. The IRS reduces your basis by the depreciation you were allowed to claim during the years of business or rental use, whether you actually claimed it or not.¹⁰ That recaptured depreciation is then taxed at a maximum rate of 25%.¹¹

Pull every tax return where you claimed depreciation, along with the depreciation schedules (typically Form 4562) showing the method and amounts. One narrow exception: if you used the simplified method for the home office deduction, depreciation is treated as zero and your basis stays intact.¹² Keep records showing which method you used each year, because the burden of proof is yours.

Proof the Home Was Your Primary Residence

The Section 121 exclusion lets you shield up to $250,000 of gain from your income, or $500,000 if married filing jointly, when the home was your primary residence.¹³ To qualify, you must have owned the home and lived in it as your primary residence for at least two of the five years before the sale. The two years don’t have to be consecutive. For married couples claiming the $500,000 exclusion, both spouses must meet the use requirement, but only one needs to meet the ownership requirement.²

Keep documents that place you at the address during those years: utility bills, voter registration records, your driver’s license, bank statements, and mail. If the IRS questions whether the property was genuinely your primary residence, these records are what you’ll produce.

If you sold before meeting the full two-year requirement, a partial exclusion may still apply if the sale was triggered by a job relocation (the new workplace at least 50 miles farther from the home than the old one), a health issue affecting you or a family member, or certain unforeseen events such as divorce, job loss, or a natural disaster.² Keep documentation of the qualifying event: a job offer letter, medical records, a divorce decree, or FEMA correspondence.

The IRS Forms You’ll File

Which forms you file depends on whether the exclusion covers your entire gain.

If the exclusion wipes out all of the gain and you didn’t receive a Form 1099-S, you generally don’t need to report the sale at all.⁴ If you did get a 1099-S, you report the sale even when no tax is owed.

When a taxable gain exists, reporting starts on Form 8949, Sales and Other Dispositions of Capital Assets. You enter the acquisition date, sale date, gross proceeds, and your adjusted basis.¹⁴ The totals flow to Schedule D, Capital Gains and Losses, and the final number carries to your Form 1040.¹⁵

If you owe depreciation recapture from rental or business use, that portion is reported on Form 4797 instead of Form 8949.¹⁶¹⁷¹⁸

How Long to Keep Everything

Hold onto property-related records until the statute of limitations expires for the tax year in which you sold the home. For most people that’s three years after the return reporting the sale was filed.¹⁹ Sold in 2026 and filed in April 2027? Keep the records through at least April 2030.

Longer is better. If the IRS suspects underreported income of more than 25%, the limitations period extends to six years. If the sale was never reported, there is no statute of limitations at all. A fireproof safe or a scanned backup in the cloud costs almost nothing compared to what you’d owe if you couldn’t prove a $30,000 kitchen renovation actually happened.
