❓ Q1: Can I file return without tax audit report?

A: No. If tax audit is applicable, return without audit report will be treated as defective. However, you can file with late audit report and pay penalty.

❓ Q2: What if turnover is ₹99 lakh - just below ₹1 crore?

A: No tax audit required if turnover doesn't EXCEED ₹1 crore. At ₹99 lakh, you're safe.

❓ Q3: Is GST included in turnover calculation?

A: No. If GST is shown separately in books of account, it should be excluded from turnover calculation.

❓ Q4: Can I opt for Section 44AD after doing tax audit last year?

A: Yes, you can opt for 44AD in subsequent year if eligible, unless you opted OUT of 44AD (then 5-year bar applies).

❓ Q5: What if I have multiple businesses?

A: Aggregate turnover of all businesses is considered. If combined turnover exceeds limit, tax audit required.

❓ Q6: Can company secretary or cost accountant do tax audit?

A: No. Only Chartered Accountants can conduct tax audit under Section 44AB.

❓ Q7: What if CA report is delayed beyond due date?

A: Penalty under Section 271B may apply (₹1.5 lakh or 0.5% of turnover). File as soon as possible to minimize consequences.

❓ Q8: Is bank statement enough for cash transaction proof?

A: Yes. For enhanced limit eligibility, bank statements showing digital transactions are good evidence.

❓ Q9: What about UPI, NEFT, RTGS payments?

A: These are NOT cash. They qualify for enhanced ₹10 crore limit benefit.

❓ Q10: Can I revise tax audit report once filed?

A: No. Unlike return of income, tax audit report cannot be revised. File carefully.
