Due-date questions people ask.
When is GSTR-3B due?
By the 20th of the next month if you file monthly. Under QRMP, by the 22nd or the 24th of the month after the quarter, depending on the state of your principal place of business. Pick your state in the calendar to see which.
What changed for TDS from April 2026?
The Income-tax Act 2025 and the Income-tax Rules 2026 came into force on 1 April 2026. The deposit dates stay the same: the 7th, and 30 April for March. The returns have new numbers: Form 138 for salary (was 24Q), 140 for residents (was 26Q), 144 for non-residents (was 27Q) and 143 for TCS (was 27EQ). TCS returns are now due on the same dates as TDS returns.
Has any due date been extended this year?
Three so far: GSTR-3B for March 2026, to 21 April 2026; the tax audit report for FY 2025-26, to 21 October 2026; and income-tax returns for audit cases, to 21 November 2026. The list on this page shows each with its notification.
If a due date falls on a Sunday, can I file the next day?
Don’t count on it. GST law has no general rule that moves the date, and an extension comes only by notification. File by the date shown, or the working day before.
How do I add these dates to Google Calendar or Outlook?
Choose what applies to you, then use “Add to calendar” to download an .ics file. In Google Calendar, open Settings, then Import. In Outlook, open the file or use Add calendar, then Upload from file. Each date comes in as an all-day event with a reminder the day before.
When are PF and ESI due?
Both by the 15th of the next month: EPF contributions with the monthly upload, and ESI contributions within 15 days of the month’s end.
Do I need to file GSTR-9?
Not if your turnover for the year is up to ₹2 crore: that has been exempt from FY 2024-25 on. Above ₹2 crore, GSTR-9 for FY 2025-26 is due by 31 December 2026, and above ₹5 crore, GSTR-9C with it.
Is what I choose saved or sent anywhere?
