How Long to Keep Tax Records

By Tom, CPA · Updated October 27, 2026

Part of: Tax Planning

TL;DR: Keep supporting records at least 3 years (7 to be safe), basis records until the asset is sold plus 3 years, and returns, Form 8606 and estate documents for life.

Somewhere in America is a garage with 40 years of tax returns in banker's boxes, kept "just in case." Somewhere else is a person who shreds receipts the day the refund arrives. Both are wrong, in opposite directions. The tax code is 4 million words long; you need about 400 of them to know what to keep, for how long, and what you can finally throw away.

The short answer is three years for most return records, but the exceptions are where people get burned: property basis, carryforwards, retirement account basis and unfiled years. This checklist is as of Oct 2026, based on IRS guidance.

CPA Warning Label: Losing basis records can make you pay tax on money that was never income. Keep property and investment basis files until the sale year closes.

The core retention periods

The IRS ties record retention to the period of limitations, the time during which you can amend a return or the IRS can assess more tax:

Practical default: keep each year's return and supporting documents for at least seven years, which covers nearly every common exception, and keep the returns themselves permanently. A PDF takes almost no space, and the IRS charges a fee and takes weeks to send copies of old returns, while free transcripts show only some line items. Keeping your own copy is cheaper than any of that.

Keep until disposition, plus the limitations period

Some records support numbers that affect future returns. Keep them until the asset is sold and then for the retention period of the return reporting the sale:

• Home purchase and improvement records: closing statements, receipts for additions and major improvements. They establish basis for figuring gain on sale.
• Rental property records: purchase documents, improvements, depreciation schedules. See rental property tax records.
• Investment purchase records: trade confirmations, reinvested dividends, inherited-asset valuations. Basis determines short- vs long-term gains and their size.
• Business equipment: purchase and depreciation records.
• Carryforwards: capital losses, passive losses, charitable carryovers and NOLs, back to the year they arose.

Keep for life (or close to it)

• Filed tax returns. Copies of every return.
• Form 8606 showing nondeductible IRA contributions and Roth conversions. Without it, you may pay tax twice on withdrawals.
• Roth IRA first contribution year, which starts the 5-year clock.
• Estate and gift returns (Forms 706 and 709), and appraisals of inherited property.
• Divorce decrees and agreements affecting alimony, dependents or property basis.
• Records related to long-term care, disability or health coverage that affect taxability of benefits; see long-term care planning.

Checklist: what to keep each year

• W-2s, 1099s (INT, DIV, B, R, NEC, K, G, SSA), K-1s, 1098s and 1095s.
• Receipts and statements for deductions: charitable acknowledgments, medical bills, property tax and mortgage interest statements.
• Business income and expense records, mileage logs, home office measurements.
• Estimated tax payment confirmations and extension confirmations.
• Childcare provider details and payments.
• HSA contributions and distribution receipts. HSA receipts can be reimbursed years later, so keep them until reimbursed and then for the limitations period.
• IRS notices and your responses.
• Credit card annual statements can help reconstruct expenses; see choosing a first credit card if you want one card for deductible expenses.

Checklist: what you can usually toss

• Supporting documents for returns past the retention period, unless they establish basis or carryforwards.
• Monthly bank and brokerage statements once you have the year-end 1099s, unless they support a deduction or basis.
• Pay stubs after you reconcile them with your W-2.
• Utility bills, unless you claim a home office.
• Receipts for personal purchases with no tax or warranty relevance.

Shred anything with your SSN or account numbers. Identity thieves love an unshredded W-2.

Digital records

The IRS accepts electronic records if they are legible, complete and retrievable. Practical setup:

1. One folder per tax year, plus a permanent "basis" folder per property or account.
2. Scan paper receipts promptly; thermal-paper receipts fade.
3. Download annual statements from each account every January; brokers and banks do not keep them online forever.
4. Keep two backups, one off-site or in the cloud, with encryption.
5. Download your IRS account transcripts occasionally as a cross-check.

Special situations

• Divorce: get copies of joint returns and basis records for any property you keep before the split; the other spouse may hold the files.
• Death of a spouse or parent: keep date-of-death valuations and appraisals permanently. They usually set the stepped-up basis for inherited assets, and heirs will need them when they sell, sometimes decades later.
• Moving between states: keep records showing your move date and domicile change. States audit former residents claiming they left, and the burden is often on you.
• Self-employed: keep invoices, bank deposits and expense records together, and keep asset records until the asset is disposed of plus the limitations period.
• Employers of household workers: keep payroll records at least four years.
• Gifts received: keep the donor's basis records, because your basis is generally the donor's basis.

When in doubt, ask one question: does this document prove a number that is on a return I could still be asked about, or a number on a future return? If yes, keep it.

Illustration:

Morgan bought a home in 2012 for $300,000 and spent $60,000 on a kitchen and an addition over the years. In 2026 Morgan sells for $700,000. Basis is $360,000 plus selling costs, so the gain is around $340,000 before selling costs. With the $250,000 single exclusion, roughly $90,000 is taxable. Without the improvement receipts, Morgan might be unable to prove the $60,000 and could owe tax on roughly $60,000 more. The 14-year-old receipts were worth keeping; the 2014 electric bills were not. Morgan then keeps the sale documents for at least three years after filing the 2026 return. Illustrative only.
