# Tax Audit for Traders

> A trader needs a tax audit under Section 44AB if trading turnover exceeds ₹10 crore (when cash transactions are within 5%, which is always the case for exchange trading) — or if they opted for presumptive taxation in any of the last five years, now declare lower profit, and total income exceeds the basic exemption limit. The audit report is due by 30 September (21 October 2026 for this year after the CBDT extension) and the ITR by 31 October (21 November 2026).

Many traders get audits they don't need, and some skip audits they do need. The answer depends on turnover computed per the ICAI Guidance Note and your presumptive-taxation history, so we check both before you pay for an audit.

Where an audit applies, it is carried out by a chartered accountant with Form 3CB/3CD, books of account and reconciliations with broker statements.

## FAQs

### Is tax audit needed just because I made a loss?

No. A loss alone doesn't trigger audit. It is needed only if turnover exceeds the limit or the presumptive-taxation rule applies to you.

### What were the due dates for FY 2025-26?

CBDT Circular 07/2026 extended the tax audit report due date to 21 October 2026 and the ITR due date for audit cases to 21 November 2026.

### What is the penalty for not getting an audit?

Under Section 271B, 0.5% of turnover, capped at ₹1.5 lakh, unless there is reasonable cause.
