What records should homeowners keep?

The IRS asks you to keep records that support the basis of your property (Publication 551). That is a short sentence carrying a long obligation, because the sale it matters for might be twenty years after the receipt.

Here is what that means in practice, and what makes a record useful rather than merely present.

When it matters, and for how long

The span is the thing people underestimate. A record starts on closing day and has to still be legible on a day nobody has scheduled yet:

The four things worth keeping

1. Your closing documents

The settlement statement from the day you bought — Closing Disclosure, ALTA statement or HUD-1 — plus the deed. This is the foundation of your basis and the only part you genuinely cannot reconstruct from memory. Which of those costs may affect basis is its own question.

2. Invoices and receipts for work done

For anything that might qualify as an improvement: the contractor’s invoice, the materials receipts, and proof you actually paid it. An estimate is not a record. A quote is not a record. What you were charged and what you paid is a record.

3. Anything that reduced what the work cost you

This is the half people forget, and forgetting it works against you in an audit rather than for you. Keep documentation of:

• Energy credits or rebates claimed on the work
• Insurance payouts for damage, and any casualty loss deducted
• Utility or municipal subsidies toward a project

4. Records of improvements you later removed

An improvement that is no longer part of the home generally comes out of basis. If you fitted a kitchen in 2011 and replaced it in 2023, both facts matter — and the second one is the one nobody writes down.

Keeping the records is not the hard part. Knowing in twenty years which receipt goes with which project, and whether the 2019 bathroom is still the 2019 bathroom, is the hard part. That is a cataloging problem, not a storage problem.

What makes a receipt actually useful

A photograph of a faded thermal receipt showing $8,400 and nothing else is close to worthless a decade on. A useful record answers four questions without anyone having to remember:

• Whatwas done — “replaced roof, full tear off”, not “roof”
• When— the date of the work, which may not be the date on the invoice
• How much— and whether that figure is before or after any rebate
• Whodid it — a contractor’s name and number makes a query answerable years later

The photograph is the evidence. The four answers are what make the evidence findable and legible. A pile of images in a phone gallery has the first and none of the second.

How long to keep it

The usual advice about keeping tax records for three years does not apply here, and following it would be a mistake. Basis records support a transaction that has not happened yet, so they need to survive until after you have sold and the return covering that sale is closed to examination (Publication 523).

In practice: for as long as you own the home, plus several years. If you roll into another property, the same logic starts again for that one.

Where to keep it

Anywhere you will still have access in fifteen years, and anywhere a house fire does not also destroy. That rules out a single paper folder in the house the records describe, which is where most people keep them.

Cloud storage works. So does a shoebox plus a scan. What matters more than the medium is that the catalog — what, when, how much, who — lives with the documents rather than in your head.

The honest argument for doing it now

Nobody reconstructs fifteen years of home improvements accurately from memory. What actually happens is that the projects with surviving paperwork get counted and the rest are guessed at or dropped. Five minutes when the contractor leaves is not diligence — it is just the only moment the information exists in one place.
