GST return due dates for FY 2026-27
Every GST registration has its own filing rhythm depending on turnover, the scheme opted for and the state in which the principal place of business is located. This calendar builds the whole year for your particular registration, from April 2026 to March 2027.
| Return | Who files it | Due date |
|---|---|---|
| GSTR-1 | Regular, monthly filer | 11th of the following month |
| GSTR-3B | Regular, monthly filer | 20th of the following month |
| GSTR-1 (quarterly) | QRMP | 13th of the month after the quarter |
| IFF | QRMP, optional | 13th of the following month |
| PMT-06 | QRMP, first two months of a quarter | 25th of the following month |
| GSTR-3B (quarterly) | QRMP | 22nd or 24th, depending on the state |
| CMP-08 | Composition dealer | 18th of the month after the quarter |
| GSTR-4 | Composition dealer, annual | 30 June following the year |
| GSTR-5 / 5A | Non-resident / OIDAR | 13th / 20th of the following month |
| GSTR-6 | Input Service Distributor | 13th of the following month |
| GSTR-7 / 8 | TDS deductor / TCS collector | 10th of the following month |
| GSTR-9 and 9C | Annual return and reconciliation | 31 December following the year |
The 22nd and 24th split for QRMP
A QRMP taxpayer files the quarterly GSTR-3B by the 22nd if the principal place of business is in a Category X state, and by the 24th if it is in a Category Y state. Category X covers the southern and western states and union territories; Category Y covers the northern, central and eastern ones. Selecting your state above applies the right date automatically.
Late fee and interest
Late fee runs at ₹50 a day, being ₹25 each under central and state tax, and ₹20 a day for a nil return. Interest on tax paid late is 18% a year under Section 50 of the Central Goods and Services Tax Act, 2017, and 24% where input tax credit has been wrongly availed and utilised.
The three-year bar
Since 1 July 2025 the portal permanently blocks the filing of any return once three years have passed from its due date. A return not filed within that window can no longer be filed at all, which makes old pending periods worth clearing before the door closes.
What happens if you keep missing dates
Two consecutive defaults in GSTR-3B block e-way bill generation under Rule 138E. Your buyers cannot take input tax credit until your outward supplies appear, and continued non-filing can lead to suspension and then cancellation of the registration.
Disclaimer
This calendar sets out the ordinary statutory due dates for the returns and registrations you have selected. Due dates are extended, deferred or varied by notification more often than any other GST compliance, and an extension may apply only to particular states, taxpayer categories, return types or tax periods. A due date falling on a holiday is not automatically shifted. The calendar does not know your registration status, the schemes you have actually opted into, or any order or notification specific to you. Treat the date shown on the GST portal against your own registration as the final word, verify against the latest notifications before filing, and consult a professional before acting. No liability is accepted for any action taken on the basis of this output.
