How Long to Keep Tax Returns and Tax Records

Keep tax returns and their supporting records for three years in most cases. Keep them six years if you left off income worth more than 25% of the gross income shown on the return, seven years if you claimed a loss from worthless securities or a bad debt deduction, and indefinitely if you never filed a return or filed a fraudulent one. Employment tax records get at least four years. Property records run until the period of limitations expires for the year you sell the property, which can be decades after you bought it.

How long should you keep tax returns?

The IRS does not publish one number, and that is the source of most of the confusion. What it publishes is a set of periods tied to what happened on the return, because the retention period is really the period of limitations: the window in which the IRS can still assess more tax, or you can still claim a refund. Once that window shuts, the records behind it stop mattering.

Here is every rule the IRS states, in the order it states them.

Notice what the six-year rule actually says. It is not triggered by a small mistake or by rounding. It applies when unreported income exceeds a quarter of the gross income you did report, which is a substantial omission. Most filers never come near it. But if you are self-employed and your income arrives from a dozen sources, you are the person most likely to miss a chunk without noticing, which is why the profession's habit of saying "keep everything seven years" grew up around business filers rather than around W-2 employees.

When does the three-year clock actually start?

From the date you filed, not from the tax year, and not from April 15. A return for the 2025 tax year filed on March 1, 2026 starts its clock on the filing date. File the same return late, in September 2026, and the whole window slides six months later with it.

The one wrinkle worth knowing: a return filed before the due date is generally treated as filed on the due date. So filing your 2025 return in February 2026 does not buy you an earlier expiry than filing it on April 15, 2026. Filing late, on the other hand, genuinely does extend how long the IRS can look at you, which is one of the quieter costs of missing a deadline. The penalties are the loud part, and what happens if you file taxes late covers those in detail.

How many years of tax returns should you keep, document by document?

The return itself and the paperwork behind it do not always deserve the same treatment. Returns are small, cheap to store, and occasionally demanded by people who are not the IRS. Supporting records are bulky and genuinely can be thrown out.

The property row is the one that catches people out. If you bought a house in 2009, put a new roof on it in 2017 and sell it in 2031, the 2009 closing statement and the 2017 roof invoice are both still live records in 2031, because together they set your basis and therefore your taxable gain. The three-year rule never applied to them in isolation. It applies to the year of the sale, and only starts then.

How long do I need to keep tax records if I am self-employed?

Six years is the working answer, and the reason is exposure rather than paranoia. Self-employed income arrives from many payers, some of whom send a 1099 and some of whom do not, so the omission that triggers the six-year rule is genuinely reachable. Business expense records also carry more weight, because a deduction you cannot support is a deduction you can lose.

That reporting gap is widening, not closing. The One Big Beautiful Bill Act restored the Form 1099-K threshold to more than $20,000 in gross payments and more than 200 transactions, and the 1099-NEC and 1099-MISC threshold rises from $600 to $2,000 for payments made from 2026 onward. Fewer forms will arrive. The income is taxable regardless, so your own books, not the 1099s, become the record that has to hold up.

Practically, that means keeping five things for six years: your income ledger, your expense records by category, your mileage log, your asset purchase invoices for anything you depreciated, and proof of the estimated tax payments you made. The tax documents checklist covers what each of those looks like at filing time.

Why your state may want records longer than the IRS does

Federal retention rules are not the whole picture, because state tax agencies run their own clocks and several are longer. California is the clearest example: under Revenue and Taxation Code section 19057, the Franchise Tax Board generally has four years from the later of the original due date or the filing date, against the federal three. Throw out a California return's records at the three-year mark and there is a full year left in which the state can still ask about them.

The practical rule is to retain to the longest applicable period, not the federal one. If you file in a state at all, four years is a safer floor than three, and it costs almost nothing to hold the extra year. If you file in more than one state, the longest of them governs how long you hold everything, since the underlying records are shared. Multi-state tax filing covers how those returns interact in the first place.

Non-tax demands run longer still. Mortgage lenders routinely ask for two years of returns, some visa and immigration filings ask for more, and insurers and creditors set their own requirements. The IRS says this out loud in its own guidance: an insurance company or creditor may require you to keep records longer than the IRS does.

Can I keep tax records digitally instead of on paper?

Yes, and the IRS has said so since 1997. Revenue Procedure 97-22 sets out the requirements for an electronic storage system that images paper documents, and it applies to all books and records you are required to retain. Scanned receipts, invoices, checks and statements are acceptable substitutes for the paper originals when the system meets the standard.

What the standard asks for is unglamorous but specific: an accurate and complete transfer of the original, an index that lets you retrieve a document by any designation used on it, the ability to reproduce legible hard copies on demand, quality assurance testing of your procedures, reasonable controls against unauthorized access, and retention for the full statutory period. Once you have tested the system and confirmed readable copies come back out, the original receipt can be disposed of.

Two things separate a compliant archive from a folder of photos. The first is the index: a phone camera roll of 900 receipts fails the retrieval requirement, because you cannot pull the one the IRS asks about. The second is legibility, and thermal receipts are the problem case, since they fade to blank within a couple of years whether or not you meant to keep them. Scanning those early is the whole point. Running them through a tool that turns receipt images into searchable line-item data solves both requirements at once, since you end up with the image and a queryable record of what was on it rather than a pile of files named IMG_4471.

What if I threw out records I still need?

Some of it is recoverable from the IRS directly, at no cost. Tax return transcripts, which show most line items from your original return, are available for the current tax year and the three prior years through the automated mail and phone services. Wage and income transcripts are the more useful ones: they list the W-2s, 1099s and other information returns filed under your Social Security number, and the IRS may hold up to ten years of them.

A wage and income transcript will not reconstruct your deductions, since nobody files an information return reporting your business mileage. But it rebuilds the income side of an old return completely, which is the half the IRS actually cross-checks. For the deduction side, bank and card statements are the usual fallback, and where those do not exist, the honest answer is that the deduction goes.

How long to keep tax records after someone dies

Longer than feels necessary, and by the same logic as everything else here. The final individual return has its own three-year period. Where an estate return was filed, the records supporting the valuations should be kept until that return's period of limitations expires. And any asset that passed to an heir carries its date-of-death value forward as the new basis, which means the appraisal or valuation record has to survive until the heir eventually sells, exactly like the property rule above.

Executors generally hold everything for at least four years past the final filing, and keep valuation records with the asset rather than with the estate paperwork, so they travel to whoever inherits.

What to do when the retention period ends

Shred anything with a Social Security number, an account number or a date of birth on it, which is most of a tax file. Old returns and W-2s are close to a complete identity theft kit, and the retention period expiring does not make the data less sensitive. Digitize before you shred if you want the record without the box, keeping in mind the Revenue Procedure 97-22 requirements above.

The one category not to shred on schedule is the returns themselves. They are a few megabytes each as PDFs, they answer the prior-year AGI question the IRS asks every time you e-file, and they are what a mortgage underwriter asks for two years of. Keep the returns, thin out the supporting records, and let the period of limitations decide the rest.

When it comes time to file this year's return, TaxFile reads the W-2s and 1099s you upload, builds your federal and state returns from them, surfaces the deductions your documents support, and runs an error check before you approve anything. The tax documents checklist is the place to start if you are still gathering, and tax preparation services compares the routes if your return has grown past what software should handle.

This is general information, not tax advice. Retention periods depend on your own facts, and a credentialed preparer should review anything unusual.
