AY 2026-27 extension: CBDT Circular No. 07/2026 (28 Sep 2026) extended the tax audit report (3CA/3CB-3CD) due date from 30 Sep 2026 to 21 Oct 2026, and the ITR due date for audit cases from 31 Oct 2026 to 21 Nov 2026 (persons at Sl. No. 2 of Explanation 2 to s.139(1); not s.92E transfer-pricing cases). Source: incometax.gov.in – Circular 7/2026. The .ics and CSV downloads use these dates. For later years, check the latest CBDT notice.

Please check before relying on it. These are the usual statutory due dates. Government extensions, state Professional Tax, and dates that fall on holidays are not applied, so confirm on the GST portal, the Income Tax portal and the MCA portal. This is a free planning aid, not professional advice.

How it is built: one HTML file with plain JavaScript and no third-party code. The .ics output follows RFC 5545 (iCalendar). Its approach is similar to the MIT/ISC-licensed ical-generator and ics libraries, but no code from them is bundled.
