DateTypeWhat

Statutory due dates by rule. The government often extends dates by notification; check the GST and income-tax portals. The .ics file has a reminder 3 days before each date and works with Google Calendar, Apple Calendar and Outlook.

This tool is for understanding and preparation only. Results are estimates based on the assumptions shown. File on the official channels.

How the dates are worked out

  • GST, monthly filers. GSTR-1 by the 11th and GSTR-3B by the 20th of the next month.
  • GST, QRMP. IFF by the 13th and PMT-06 payment by the 25th for the first two months of a quarter; GSTR-1 by the 13th and GSTR-3B by the 22nd or 24th (depending on your state) after the quarter. GSTR-9 annual return by 31 December.
  • TDS. Deposit by the 7th of the next month (30 April for March). Quarterly statements 24Q/26Q by 31 July, 31 October, 31 January and 31 May; 27EQ (TCS) by the 15th. Form 16 by 15 June.
  • PF and ESI. By the 15th of the next month.
  • Advance tax. 15% by 15 June, 45% by 15 September, 75% by 15 December and 100% by 15 March. Presumptive taxpayers pay all of it by 15 March.
  • Income-tax return. 31 July for most people, 31 October for audit cases (audit report by 30 September), and 31 December for belated or revised returns.

Dates that fall on a holiday are not moved, and extensions announced by the CBDT or CBIC are not included. Check the portal before you rely on a date.
