How Long Should You Keep Tax Records? The IRS Rules by Document Type

The honest answer to “how long should I keep this?” depends entirely on what kind of record it is and what happened on your return. The IRS’s retention rules are tied directly to how long it (or you) can still legally act on a given tax year — called the period of limitations. Here’s the breakdown by situation, plus practical guidance on what to actually do with everything once you’re past the retention window.

The Core Rule: 3 Years

For most taxpayers in most years, the standard retention period is 3 years from the date you filed your return (or the due date, if later). This is the window during which:

• You can file an amended return to claim an additional refund or credit you missed.
• The IRS can audit your return and assess additional tax.

If you filed your 2025 return in April 2026, the IRS generally has until April 2029 to question it, and you have until then to amend it if you find an error in your favor. Once that window closes, both sides are generally done with that tax year (with the exceptions below).

When You Need to Keep Records Longer

6 years — substantial underreporting. If you omitted more than 25% of the gross income shown on your return, the IRS gets double the normal window: 6 years instead of 3. This also applies if you failed to report more than $5,000 in specified foreign financial assets, even if that omission is under the 25% income threshold.

7 years — worthless securities or bad debt. If you claimed a deduction for a loss from securities that became completely worthless, or a bad debt deduction (money someone owed you that you’re writing off), keep those records for 7 years from the due date of that return.

Indefinitely — no return filed, or fraud. If you never filed a return for a given year, or if you filed a fraudulent return with intent to evade tax, there is no statute of limitations — the IRS can pursue those years at any point in the future. This is also a strong practical reason to always file, even a late return with money owed: it starts the clock running on a period of limitations that otherwise never begins.

4 years — employment tax records. If you have employees (including household employees or a small business), keep employment tax records for at least 4 years after the tax becomes due or is paid, whichever is later.

What Counts as a “Record” Worth Keeping

The retention windows above apply broadly to anything that supports what’s on your tax return, which typically includes:

• Income documents: W-2s, 1099s (NEC, INT, DIV, K, MISC, etc.), K-1s
• Deduction and credit support: receipts for itemized deductions, charitable donation records, medical expense receipts, mortgage interest statements (Form 1098), childcare payment records
• Investment records: brokerage statements, records of what you originally paid for an investment (your “cost basis”) — keep these for as long as you hold the investment, plus the standard retention period after you sell
• Home records: purchase documents, records of home improvements, and sale documents — keep these for as long as you own the home, plus 3 years after you sell, since they affect your capital gains calculation (see capital gains exclusions when selling your home)
• The tax return itself: many people choose to keep copies of the actual filed return indefinitely, even after supporting documents are discarded, since it’s a compact record of what was reported

What About Medical Bills and Bank Statements That Aren’t Tax-Related?

The IRS retention rules only govern documents relevant to your taxes. For general financial recordkeeping (not audit-related), common practical guidance is:

• Bank and credit card statements: most people keep 1 year for reference, longer only if they support a tax deduction or a major purchase warranty/dispute
• Pay stubs: until you reconcile them against your W-2 and annual Social Security statement, then they can be discarded
• Medical bills: 1 year for insurance dispute purposes, longer if you deducted medical expenses on your tax return (in which case the standard 3-7 year tax retention rules apply to those specific bills)
• Utility bills, ATM receipts, deposit slips: generally safe to discard once reconciled against a monthly statement, unless tied to a tax deduction (like a home office utility deduction)

Practical Tips for Managing Records

Digitize everything. The IRS accepts scanned/digital copies of most records as long as they’re a legible, complete reproduction of the original. A cloud-stored folder organized by tax year eliminates the physical storage problem entirely.

Set a yearly purge date. Pick a date each year (like Tax Day, or right after you file) to review and discard records that have passed their retention window. This keeps the task manageable instead of becoming a decade-deep paper archive.

Shred, don’t just toss. Tax records contain Social Security numbers, account numbers, and other identity-theft-relevant information. Shred physical documents rather than throwing them in the regular trash.

When in doubt, keep it longer. If you’re not sure which category a document falls into (for example, unclear whether a deduction might later be questioned), it costs little to keep it for the longer 7-year window rather than the standard 3.
