Quick answer
What are the main monthly GST and TDS due dates?
TDS is paid by the 7th, GSTR-1 is filed by the 11th and GSTR-3B by the 20th of every month, and PF and ESI are paid by the 15th. Quarterly filers have their own dates on the 13th, 18th, 22nd and 25th.
Every month
| Date | What is due | Who |
|---|---|---|
| 7th | TDS and TCS deposit for the previous month (March deposit is due 30 April) | Businesses that deduct TDS |
| 11th | GSTR-1 for the previous month | GST, monthly filers |
| 15th | PF and ESI payment for the previous month | Employers |
| 20th | GSTR-3B for the previous month | GST, monthly filers |
| 25th | PMT-06 GST payment, first two months of each quarter | GST, quarterly (QRMP) filers |
Dates follow the rules in force on 1 October 2026. When the government extends a date, the extended date applies. File a day or two early, because portals slow down near due dates. From April 2026, many income tax forms have new numbers; we show both.
