- All income documents (W-2s, 1099s, K-1s)
- Receipts for deductible expenses
- Charitable donation records
- Medical expenses
- Business expenses and mileage
- Investment purchase records (for cost basis)

Final Tips
- File on time even if you can’t pay. The failure-to-file penalty is much higher than the failure-to-pay penalty.
- Keep copies for 3-7 years. The IRS can audit returns up to 3 years back (6 years for substantial understatements).
- Use direct deposit for refunds. It’s faster and more secure than paper checks.
- Check state requirements. Some states have different rules for deductions, credits, and filing deadlines.
- When in doubt, file. Even if you’re not required to file, you may be missing out on refundable credits.
