- Compile bank statements that match the income reported.
- Keep sales receipts and point‑of‑sale summaries for cash businesses.
- Match each income source to the corresponding line on your tax return.
- Verify that the amounts reported in your records align with the totals on your tax forms.
- Check for any gaps or unexplained spikes that could trigger an audit.
- Maintain a timeline of when each revenue entry was received.
| Document Type | Retention Time |
|---|---|
| W‑2, 1099 | 7 years |
| Bank Statements | 7 years |
