What is the due date for a tax audit report?

Short answerThe tax audit report (Form 3CA/3CB-3CD) is due by 30 September of the assessment year, and the income-tax return for audit cases by 31 October. File the audit report first — the return can’t be filed correctly without it.

30 September report, 31 October return

The report goes first, then the return. Confirm exact dates, which are occasionally extended.

Order matters

The return references the audit report’s acknowledgement, so the audit must be filed and accepted first.
