Records Retention Guide
How long to keep every document — tax returns, pay stubs, deeds, warranties — with the IRS windows and the cases where the clock never starts.
US-oriented guidance. The tax periods track IRS audit windows: 3 years normally, 6 if income was underreported by 25%+, 7 for bad-debt claims — keeping 7 covers all of them. Scan the keep-forever pile; paper fades, house fires happen.
"Keep it seven years" is not a rule
There are three audit windows, not one, and seven is simply the largest of them:
| Window | Applies to |
|---|---|
| 3 years | the ordinary limit on assessing more tax |
| 6 years | income understated by more than 25% |
| 7 years | a loss from a worthless security or bad debt |
Seven was adopted as a single figure so nobody has to work out which case they are in. It is good advice and it is not a legal period — the one that applies to most people most years is 3, so the usual guidance keeps records 2.3 times longer than needed. It does not cap anything at the far end either: a return that was never filed, or that was fraudulent, has no time limit at all. Knowing that changes the middle cases. A pay stub that has already reconciled against its W-2 is doing nothing after a year. A receipt backing a deduction is doing something for the full seven.
Most of this list is not a number of years
Of the 30 entries here, 9 are a fixed period you could put on a calendar, 14 are conditional and 7 are permanent. The conditional group is the largest, and a conditional rule cannot be automated — which is exactly why those are the ones that go wrong. 7 of them are tied to something you own rather than to a date, and every one of those sits under Money or Home & car — never under Everyday.
The extreme case is home improvement receipts. Kept for ownership plus seven years after the sale, a 30-year homeowner is holding them for 37 years — 5.3 times the longest tax window on the page, for a category most people shred annually. They raise the cost basis of the house and directly reduce the capital-gains tax when it is sold.
One more distinction worth making: 9 entries sit in the "Forever" category and only 7 of them actually say forever. A passport is filed there and kept only until renewed; a retirement basis record is filed under Taxes and kept for good. The heading and the rule are not the same thing. The asymmetry underneath all of it is simple. Keeping a document too long costs a drawer. Shredding one too early costs somewhere between an afternoon and a tax bill you cannot dispute.

Frequently asked questions
How long should I keep tax returns?
Three years is the general IRS window for both amending a return and being audited. It extends to six years if income was understated by more than 25 per cent, and there is no limit at all for a fraudulent return or one never filed — in those cases the clock never starts.
What should I keep permanently?
Records that prove something ongoing: birth and marriage certificates, deeds and titles, wills, records of major home improvements affecting your cost basis, and retirement account contribution records. Most of these are difficult or impossible to reconstruct if lost.
How long do I keep records for a property I sold?
Generally three years after filing the return reporting the sale — but the supporting records go back much further, because improvements made over decades affect the cost basis. That is why home improvement receipts should be kept for as long as you own the property and then through the tax window afterwards.
Are digital copies acceptable?
For most purposes yes, and the IRS accepts electronic records provided they are legible and complete. Some documents still want the original — notarised instruments, certain titles, and anything with a raised seal. Keeping a scan alongside the original costs nothing and protects against loss.
What about pay stubs and bank statements?
Pay stubs generally until you reconcile them against the annual summary, then discard. Bank and credit card statements for a year for routine purposes, and longer where they support a tax deduction — in which case they follow the tax return's own retention period.
How should I dispose of documents?
Cross-cut shredding for anything carrying an account number, a national insurance or social security number, a date of birth or a signature. Bin-raiding for identity theft is unglamorous and effective, and a strip-cut shredder is not much of an obstacle.
