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.

Plan backwards from the deadline

Because the return for an audit case can’t be filed until the audit report is uploaded and accepted, work backwards: aim to close your books and hand records to your auditor well before the September report deadline, leaving room for queries. A late audit report not only attracts the Section 271B penalty but also delays the return, which can mean interest under Sections 234A and 234B and the loss of the right to carry forward business losses. The dates are occasionally extended by the CBDT, but treating the original deadline as firm is the safe approach — extensions are announced late and shouldn’t be relied on. A practical timeline is to finalise books by July, give the auditor August for fieldwork and queries, file the report in September, and the return in October — with a buffer for unexpected reconciliation issues.
