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.
Key Stat: 73% of IRS audits involve records older than 3 years. Proper retention protects you from penalties, supports your deductions, and provides peace of mind.

Keep Permanently

Special Situations
Real Estate
What to keep: Purchase records, improvement receipts, depreciation schedules
Retention period: Until 3 years after you sell the property and file the return reporting the sale
Why: Calculate capital gains, support depreciation deductions
Example: You buy a rental property in 2020 and sell it in 2024. Keep all purchase records, improvement receipts, and depreciation schedules until 2028 (3 years after filing your 2024 return).
Real-World Example: A client sold a rental property and couldn’t find the purchase closing statement. Without proof of cost basis, the IRS assessed an additional $45,000 in capital gains tax. Proper record retention would have saved them thousands.
Stocks and Investments
What to keep: Purchase confirmations, reinvestment records, dividend statements
Retention period: Until 3 years after you sell the investment and file the return reporting the sale
Why: Calculate cost basis, determine capital gains/losses
Note: For mutual funds with reinvested dividends, keep all reinvestment records to calculate accurate cost basis.
Business Assets
What to keep: Purchase records, depreciation schedules, improvement records
Retention period: Until 3 years after you dispose of the asset and file the return reporting the disposition
Why: Support depreciation deductions, calculate gain/loss on sale
Example: You buy equipment for $50,000 in 2018 and sell it in 2024. Keep all purchase records and depreciation schedules until 2028 (3 years after filing your 2024 return).
Digital vs. Paper Records
The IRS accepts digital records. Scanning documents and storing them electronically is acceptable—as long as they’re legible, organized, and backed up.
Digital Record Best Practices
Scanning Standards:
- Scan at 300 DPI or higher
- Use PDF format (not JPEG or PNG)
- Ensure text is legible
- Use OCR (optical character recognition) when possible
Organization:
- Organize by year and category
- Use consistent folder structure
- Example:
Tax Records/2024/Business Expenses/
Naming Conventions:
- Use consistent file names
- Include date, document type, and description
- Example:
2024_W2_EmployerName.pdf - Example:
2024_Receipt_OfficeSupplies_Staples.pdf
Backup Strategy:
- Primary: Cloud storage (Google Drive, Dropbox, OneDrive)
- Secondary: External hard drive (updated monthly)
- Tertiary: Off-site backup (safe deposit box or secondary cloud)
Security:
- Use encrypted storage for sensitive documents
- Enable two-factor authentication on cloud accounts
- Use strong, unique passwords
- Update backup regularly
Pro Tip: Use a document management app like Evernote, OneNote, or a dedicated tax app to capture receipts immediately. Snap a photo, categorize it, and sync to cloud storage. This prevents lost receipts and simplifies year-end tax prep.
