Cash Transaction Limits and Evidence: Tax Red-Flag Control Checklist
Cash transactions can trigger tax questions even when income is genuine. The defence is source evidence, purpose trail, counterparty details and consistency with books/AIS.
For broader context, see the Income Tax and Salary Hub.
Detailed analysis
Cash issues usually surface through AIS/SFT data, bank deposits, property transactions or scrutiny notices. The taxpayer must explain source and use, not just say 'cash available'.
Practical example
A small trader deposits ₹9.5 lakh cash after festive sales. Strong file: daily sales register, GST reconciliation, cash book, bank deposit slip, cash-on-hand movement and ITR turnover tie-out. Weak file: only bank statement.
Evidence and control checklist
| Area | What to check | Evidence to save |
|---|---|---|
| Cash deposits | Source, date-wise cash book and business reason. | Cash book, sales register and bank deposit slip. |
| Loans/gifts | Counterparty, relationship and repayment terms. | Agreement, PAN, bank/cash trail and confirmation. |
| Cash expenses | Business purpose and statutory allowance/disallowance review. | Bills, vouchers and approval. |
| Property/capital transactions | Agreement, consideration and reported value. | Sale deed, stamp data and AIS entry. |
| Notice response | Source-to-deposit bridge. | Cash-flow statement and annexures. |
