What to Do With Old Tax Returns

By Jason Su · Updated October 9, 2026

Most old tax returns can be shredded three years after the filing deadline, and a few categories have to be kept far longer. The ones people throw away by mistake are almost never the returns themselves — they are the records behind them: the paperwork for a house you still own, the receipt from a twentieth-anniversary gift, the file from a year you never filed at all.

The rule that catches people out is short: “expired for tax purposes” is not the same as “safe to destroy.” The IRS says so directly, and points out that an insurer or a creditor may need a record longer than the IRS does.

The short answer, by category

The IRS measures almost everything from the period of limitations — the window in which you can amend a return, or the agency can assess more tax.

One detail at the start, because it changes the math: the clock runs from the due date, not the day you actually filed. A return filed in February is treated as filed in April.

Situation	How long to keep the records
An ordinary filed return, nothing unusual	3 years
You filed a claim for a credit or refund after filing	3 years from filing, or 2 years from paying, whichever is later
You claimed a loss from worthless securities or a bad debt	7 years
You underreported income by more than 25%	6 years
You never filed the return	Indefinitely
The return was fraudulent	Indefinitely
Employment tax records	At least 4 years

The 6-year and 7-year entries are not arbitrary. One covers a large understatement of income, the other a specific kind of claim. If neither applies to your year, three years is your number — which is why most of a box can be emptied and only a handful of folders need to stay.

That table covers the return. It does not cover the things behind it.

The records that outlive the return

Property records run on a different clock entirely. The IRS says to keep records relating to property until the period of limitations expires for the year in which you dispose of it — because that paperwork is what establishes your cost when you eventually sell, and what supports any depreciation.

In plain terms, that means:

• The purchase papers for a house you still own, including the closing statement.
• Receipts for major improvements — a roof, a kitchen, an addition. These add to your cost, which lowers the gain when you sell. Thrown away, they are gone.
• Brokerage and retirement statements that establish what you paid for investments.
• Inherited property: for anything you inherited, the starting value is generally the value on the date of the passing rather than what the person originally paid (IRS Publication 551). That makes the date-of-passing valuation the document worth keeping, not the original purchase receipt.
• Records from a nontaxable exchange, plus the records for the property you gave up. The IRS expects both sets kept until the year you dispose of the new property.

Three categories in particular are the ones people regret losing:

1. Home improvement receipts. They are the difference between a large gain and a small one, and no bank or title company keeps a copy for you.
2. Business and rental records. Deductions and depreciation can reach back years, and a return alone will not support the numbers on it.
3. Donation paperwork. If you gave away anything of value, the substantiation rules apply: a written acknowledgment from the charity, and a Form 8283 once a single item or a group of similar items is valued over $500 (IRS Publication 561).

Two years of statements will not do here. For property, “old” can mean decades.

If you are clearing out someone else’s returns

This is where most of these questions actually come from: a parent’s basement, or a house you are emptying. A few things are worth knowing before anything goes in the recycling.

Keep the returns they filed, at least for now. When someone passes, more than one return can be involved: the final individual return for the year, and any estate income tax return filed afterwards. There may also be a Form 56 to establish who is acting for the estate, and a Form 1310 if a refund is claimed for the person who passed. The IRS keeps a page on what has to be done after a passing that lists these filings and forms, and its general retention periods apply to them.

Do not start by sorting. A shoebox of returns is easy to deal with; a shoebox of receipts separated from its returns is not. Keep each year together until you know which category it falls into, and keep the property paperwork in its own folder regardless of year. See what to do with someone’s belongings for the wider order of work.

Check before you destroy anything that is not a return. Bank and brokerage statements, closing documents, business records, and anything with a Social Security number on it are not interchangeable with a 2011 return. When in doubt, keep it another year and revisit. Storage is cheap; a lost basis is not.

A missing year is often findable. If a return has disappeared but the year matters, the tax preparer may still have a copy. That will not replace your receipts, but it will tell you which years you are dealing with — which is usually the harder question.

What to actually do with the paper

Once a year has genuinely expired, the disposal question is about privacy rather than tax:

• Shred anything with a name, a Social Security number, or an account number on it. Paper goes into recycling only after it stops identifying anyone.
• A cross-cut shredder at home is enough for ordinary returns. For a large volume, a commercial shredding day is inexpensive and usually takes one trip.
• Scan selectively, not everything. The categories worth digitising are the property records you will need decades from now, and any year you might need to prove to a lender. Ten pages scanned is worth more than a hundred pages filed badly.
• Keep a one-line index of what you kept and where. A box nobody can describe is a box nobody will use — the same reason the free Document Inventory exists.
• Keep donation acknowledgments with the year they belong to. A receipt for a noncash gift is worthless once it is separated from the return that claims it.
• Ask the preparer before you give up on a year. A phone call is often faster than searching a basement, and it tells you what you are missing rather than what you already have.
• Do not keep paper in a damp garage and expect it to be usable in twenty years. If it matters, it lives indoors.

For the non-tax side of the same question — how long to keep insurance policies, deeds, and medical records — see what documents to keep and for how long.

What not to do

• Do not assume seven years is the universal number. It is not. Three years is the ordinary case, seven applies to specific claims, and property records follow their own rule.
• Do not throw out the closing papers for a house you still own, even if the return for that year is long gone.
• Do not shred a return you never filed. An unfiled return has no clock, which means the records never expire.
• Do not destroy someone else’s records before the estate work is finished. The person handling the estate may still need them, and a missing basis cannot be recreated later.
• Do not rely on the bank or the tax preparer to keep copies. Preparers keep their own files for their own reasons and for their own time limit.
• Do not keep everything forever out of anxiety either. The exception list above is short. Everything else, after seven years, is paper.

Frequently asked

Is three years really enough for an ordinary return?

For the IRS, in the ordinary case, yes — that is the window in which the return can be amended or additional tax assessed. The caveat is the one the IRS itself adds: check whether your insurance company, a lender, or a business obligation requires it longer.

Do I need to keep the return itself, or just the receipts?

Keep both for as long as the year matters. The return shows what you reported; the records show why. If you must choose, keep the records for property and the returns for years involving a business, a rental, or anything unusual.

What about W-2s and 1099s?

They support the income on the return, so they live and die with it — three years in the ordinary case, longer if the year is unusual. Anything showing income you did not report is worth keeping past that, because it explains a gap the agency may ask about later.

How long should I keep returns for someone who has passed?

The estate paperwork drives this rather than a single number. Keep the final individual return and any estate return until the estate is closed and the relevant windows have run, and keep the property records until the property is sold or distributed. If the estate is still open, nothing gets shredded.

What if I have forty years of returns in a box?

Work backwards from the most recent. Keep everything from the last seven years without thinking about it, keep property and business records regardless of age, and treat anything older than that as a one-hour sorting job rather than a weekend project. It is a smaller job than it looks — and it is worth doing before someone else has to.

Next step

Pull one year out of the box and sort it against the table above. Keep the return, shred what identifies you and has expired, and put the property paperwork in a separate folder that does not get sorted by year. Then write one line saying where the keepers live, using the Document Inventory, or work through the whole house with how to organize your paperwork.

If the box belongs to someone who has passed, start with what to do with their belongings instead — the order matters more than the sorting.
