Taxpayers subject to a tax audit must complete two linked filings for the financial year 2025-26 (assessment year 2026-27). The audit report submission is due by September 30, and the income tax return filing is due by October 31.
Who needs to follow this two-stage process
Under section 44AB of the Income Tax Act, entities that cross the prescribed turnover or income thresholds are required to undergo a tax audit. The requirement applies to businesses as well as certain professionals, with the exact trigger depending on the taxpayer type and accounting method.
Exact deadlines for AY 2026-27
For the assessment year 2026-27, the tax audit report (forms 3CA/3CB with 3CD) must be filed by September 30, 2026. The corresponding ITR must be filed by October 31, 2026. The two filings are separate steps, but the figures in the ITR should reflect the audited books.
What to prepare before each date
- By September 30, complete the books of accounts, compile vouchers and ledgers, appoint or confirm the auditor, and submit the audit report with Form 3CA/3CB and 3CD as required.
- By October 31, use the audited financials to file the ITR, ensuring consistency between the audited accounts and the return, and verify all relevant disclosures.
Notes and practical tips
- This two-stage process applies to taxpayers who are required to have a tax audit. If you do not cross the threshold, the steps may not apply.
- Late compliance can attract penalties and interest under the Income Tax Act; monitor any portal updates or extensions announced by the tax department.
Takeaway
Aligning the tax audit with the ITR helps ensure books and returns are reconciled, reducing last-minute issues. Start early to manage the deadlines smoothly.
