Which Tax Documents to Keep and for How Long: The Simple List

Almost every house has one: the shoebox, the desk drawer, or the bloated folder of “just in case” receipts. The years go by, the box grows, and nobody knows what can be tossed. Receipts from 2019? The W-2 from five years ago? The copy of the return you filed on the old computer?

The good news: the recordkeeping rules are simpler than they look. The IRS publishes exactly how long you must keep each thing, and almost everything boils down to one golden rule. Let’s get it organized.

The golden rule: three years

For the vast majority of taxpayers, the rule is: keep your return documents for at least three years from the date you filed the return (or from the due date, whichever is later).

Why three years? Because that’s the period the IRS has, in most cases, to audit you or correct you: the so-called statute of limitations. Once that time passes without the IRS opening anything, the return is closed for practical purposes. Your papers are your shield during that window.

This covers: the copy of the return, the W-2s, the 1099s, deduction and credit receipts, business expense records, and any document that supports a number you put on the return.

The exceptions that lengthen the window

There are cases where three years isn’t enough:

• Seven years if you claimed a loss from a bad debt or from worthless securities (stocks that went to zero). Keep those papers seven years.
• Six years if you omitted more than 25% of your gross income on the return. The IRS’s window extends to six years, so your documents must go with it.
• No limit if you didn’t file a return or filed a fraudulent one. In those cases the window never closes, and the recommendation is to keep records indefinitely.

The moral: if your situation is normal (you filed on time, no big omissions), three years. If there’s something unusual, the window grows. And if you ever need to amend a return (see the Form 1040-X guide) to claim an additional refund, the window is three years from the original filing: another reason not to toss anything early.

What to keep, in a concrete list

No need to keep everything. Here’s the list of what does need keeping:

• Income: all W-2s, 1099s (NEC, MISC, INT, DIV, G, R), and records of any other income.
• Deductions and credits: donation receipts, mortgage interest (Form 1098), taxes paid, large medical expenses, business expenses if you work for yourself.
• The return itself: a complete copy of Form 1040 and all the schedules for each year.
• Property: home purchase documents, improvements made to the property, and investment records. These are kept until three years after selling the asset, because the gain is calculated with the original cost.
• Employment: keep your income records until you confirm that the Social Security Administration correctly recorded your earnings for each year (you can verify it in your ssa.gov account). Your future benefits depend on that record.

How to store it (paper no longer rules)? The IRS accepts electronic records as long as they’re legible and accessible: scans, clear photos, PDF files. You don’t need the original paper for everything. What you do need is a system that lets you find the document when you need it.

• One folder per tax year (physical or digital).
• Inside, simple subfolders: income, deductions, return.
• Backup of the digital: an external drive or the cloud. One device is not a backup.

And a security tip: these documents contain your SSN and your financial data. If you keep them in the cloud, use an account with two-factor authentication; if you keep them on paper, a locked box. The shoebox on the kitchen table is not a security system.

Past the deadlines, you can get rid of papers: the practical rule

Everyday expense receipts from a year whose return has already met its three years: they can be tossed.

• Old bank statements that don’t support any deduction: they can be tossed.
• Never toss, without reviewing: property documents, investment records, and copies of the returns.

The returns, in fact — many accountants recommend keeping them forever: they take up little space and are your complete tax history.

Before tossing, shred. Tax documents are identity on paper.

What to do today, in order

1. Gather the tax papers you have scattered and sort them by year.
2. Mark each year with its retention deadline (filing year + 3 years, at minimum).
3. Scan what’s important and keep a protected digital backup.
4. Shred what’s already past its window: the shoebox can retire.
