Statutory dates are encoded as-is; there is no automatic carry-forward when a due date falls on a Sunday or gazetted holiday. Tax portals (GST, e-filing, EPFO, ESIC, MCA V3, FLAIR) accept filings/payments 24x7, so regulators treat the calendar date as binding and grant relief only by ad-hoc notification — e.g., Notification 01/2026-Central Tax moved the March-2026 GSTR-3B from 20 to 21 April 2026, and CBDT moved the AY 2025-26 tax-audit specified date from 30 Sep to 31 Oct 2025. Section 10 of the General Clauses Act 1897 (next-working-day rule) helps for physical filings with offices/courts but should not be relied on for online tax payments. The org's CA/CS should track extension notifications; the calendar should surface the statutory date with reminders ahead of it.
This is a reference calendar, not legal or tax advice. It shows statutory due dates as they stand on the review date — regulators routinely extend dates by ad-hoc notification, and none of those extensions are encoded here. Rows marked “citation being confirmed” carry a due date we trust but a statutory reference that still rests on secondary sources. Verify the current date and the provision with your CA/CS before relying on it for a filing or payment. Last reviewed: 2026-08-19.
