The reason your filing box is full isn't that you're disorganized. It's that nobody ever told you what's safe to throw away — so you kept everything, which is the same as organizing nothing.
Here's the short version, then the details. Keep forever: birth certificates, Social Security cards, titles and deeds. Keep about seven years: tax returns and the records behind them (in the US, generally — more on that below). Keep one year: pay stubs, until the W-2 confirms them. Keep until replaced: insurance policies. Keep until the warranty ends: receipts for things you'd want repaired.
That's the whole system. One honest caveat before the details: retention rules are set by governments and they change. This guide describes what's generally true in the US — it isn't legal or tax advice, and for anything with real money attached, check IRS.gov or ask a professional.
The one-glance retention table
| Document | Keep for | Why |
|---|---|---|
| Birth certificates, Social Security cards | Forever | They prove who you are |
| Marriage, divorce, adoption, citizenship, military discharge papers | Forever | Needed decades later, hard to replace |
| Titles and deeds (car, house, land) | Forever, while you own it | They prove what's yours |
| Tax returns and supporting records | ~7 years, generally (US) | Covers most IRS review windows |
| Pay stubs | 1 year, until the W-2 checks out | The W-2 replaces them |
| Insurance policies | Until the renewal replaces them | Only the current one binds anyone |
| Receipts for purchases with warranties | Until the warranty ends | Your proof if something breaks |
| Everyday receipts, utility bills | Weeks to months | Once paid and posted, they're done |
Forever: the papers that prove who you are and what you own
Some documents never expire in usefulness: birth certificates, Social Security cards, marriage and divorce records, adoption and citizenship papers, military discharge records, and the titles or deeds to anything you still own. You might not touch one for ten years — and then a passport application, a home sale, or an estate needs the original, this week.
Two rules for this pile. First, the physical original matters: raised seals and wet signatures are the document, so store these somewhere safe at home (a fire box earns its keep) rather than shredding after scanning. Second, scan them anyway — a digital copy answers most questions ("what's grandma's exact date of birth?") without a trip to the fire box, and tells you what to replace if the original ever goes missing.
These are also exactly the papers a family scrambles for at the worst possible time. If you've ever had to assemble documents after a death in the family, you know the difference between "it's all in the gray box, scanned and findable" and a week of drawer archaeology.
About seven years: tax records
In the US, generally, the IRS can review a return for three years after you file — longer in certain situations, such as substantially underreported income, and with no limit at all for fraud or unfiled returns. That's why "keep tax records seven years" became the folk rule: it comfortably covers the common cases. It's a reasonable default, not a law of nature, so check IRS.gov for the current windows.
"Tax records" means the return plus everything that backs it up: W-2s, 1099s, receipts for anything you deducted, records of charitable donations. Records for property — a house, investments — can matter for as long as you own the asset plus the review window after you sell, because they establish what you paid.
The painless way to handle this is to stop treating it as an April problem. Keeping tax documents organized year-round turns "seven years of records" from a filing project into a habit that takes seconds per document.
One year: pay stubs
Pay stubs exist to be checked against something. When your W-2 arrives in January and matches your final stub of the year, the stubs are done — the W-2 is the document that counts from then on, and it goes with that year's tax records. Until then, stubs are handy for loan applications and for catching payroll mistakes while they're still fixable.
Until replaced: insurance policies
An insurance policy is only useful while it's in force. When the renewal arrives, it replaces the old one — the expired policy binds nobody and answers nothing. So the rule is simple: current policy in, old policy out.
One exception worth respecting: anything connected to a claim. If there's an open claim, or an incident that might become one, keep every related document — the policy that was in force, correspondence, photos, estimates — until the claim is fully resolved.
Until the warranty ends: receipts
Most receipts are done the moment the charge posts correctly. The ones worth keeping are attached to a promise: the laptop with two years of coverage, the dishwasher, the mattress with the decade-long warranty you'll have forgotten by year three. Keep those receipts as long as the promise lasts, because the receipt is how you collect on it.
This is where digital wins outright. Thermal-paper receipts literally fade to blank before long warranties end; a scan doesn't. Snap the receipt the day you buy, and the paper can go.
Where the paper goes when the answer is "not forever"
Everything that doesn't need to exist as paper — statements, bills, stubs, receipts — is a better citizen as a scan. If you're staring at a full filing box, clearing out your paper documents at home is the companion project to this guide: digitize, keep the short list of originals, shred the rest. (Shred, don't toss — most of these papers carry account numbers.)
The catch with digital copies has always been finding them again, and that's the part Paperlock is built to delete. Save a document once and it reads it — what it is, who it's from, the date, the amount, when anything expires — and files it behind Face ID with no folders or naming on your part. Seven years from now, "find my 2026 tax return" or "do I still have the dishwasher receipt?" gets you the answer with the document attached. It even reminds you before warranties and IDs expire, automatically. That's the whole idea of the app, and it's coming soon to iPhone.
Retention stops being a burden the moment keeping something costs nothing. Keep the vital originals safe at home, keep everything else as a scan you can actually find, and let the shredder handle the rest.
