Tax Record Retention Guide: How Long to Keep Documents

## Why Tax Record Retention Matters The IRS generally has three years from the filing date to audit your return. But if you underreported income by more than 25%, that extends to six years. If you filed fraudulently, there's no statute of limitations. With 25+ years of experience guiding clients through IRS audits, Alan Balmer has seen the difference proper record retention makes. Keeping the right records protects you—but keeping everything forever creates clutter and risk. ## Tax Record Retention Periods at a Glance | Retention Period | Document Types | Examples | |------------------|----------------|----------| | **Permanent** | Tax returns, formation documents, retirement records | Form 1040, Articles of Incorporation, IRA contribution records | | **7 Years** | Business records, employment records, asset records | Invoices, payroll records, equipment purchases | | **3 Years** | Supporting documentation | W-2s, 1099s, deduction receipts | | **1 Year** | Minor records | Deposit slips, small purchase receipts | | **Shred Immediately** | Drafts, duplicates, expired documents | Working papers, extra copies | ## Keep Permanently These documents form the foundation of your financial and tax history.
