GST and income-tax due dates, at a glance
Most GST returns are filed for the previous tax period: GSTR-1 (outward supplies) by the 11th, GSTR-3B (summary + tax) by the 20th, TDS/TCS returns (GSTR-7/8) by the 10th, and ISD (GSTR-6) by the 13th. Quarterly QRMP filers and composition dealers have their own dates after each quarter, and annual returns (GSTR-9/9C) fall on 31 December.
Income tax has its own recurring calendar: TDS deducted in a month is deposited by the 7th of the next month (March deductions get an extended 30 April date), quarterly TDS/TCS returns (24Q/26Q/27Q/27EQ) are due the month after each quarter, advance tax falls due on 15 June / September / December / March, and ITR filing runs from 31 July (salary, non-audit) through 31 October (audit cases) and 30 November (transfer pricing), with the tax audit report due 30 September.
Pick any month above to see exactly what's due — dates with a deadline are marked right on the grid. Click a date for just that day's details, or use the GST / Income Tax chips to filter. Dates are the standard ones — extensions can move them, so confirm on the relevant portal.
Compliance due dates — FAQ
When is GSTR-1 due?

When is GSTR-3B due?
Monthly filers: the 20th of the following month. QRMP filers: the 22nd or 24th of the month after the quarter, depending on the state.

TDS deducted in a month must be deposited by the 7th of the following month — except TDS deducted in March, which non-government deductors can deposit by 30 April. The quarterly TDS/TCS return (Forms 24Q/26Q/27Q/27EQ) is due 31 July, 31 October, 31 January and 31 May for the four quarters.

31 July for salary and capital-gains income (non-audit); 31 August for other non-audit business income; 31 October for accounts requiring a tax audit; and 30 November for cases with a transfer-pricing report. The tax audit report itself (Form 3CA/3CB-3CD) is due 30 September.
What is the due date for the GST annual return?
GSTR-9 and GSTR-9C for a financial year are due on 31 December of the following year.
