Pro Tips & Statutory Advice

Practical business & compliance advice

  • GSTR-1 Due Date (11th) Monthly GSTR-1 is due on the 11th of the following month. Timely filing ensures your buyers see ITC in their GSTR-2B.
  • GSTR-3B Due Dates (20th / 22nd / 24th) Monthly GSTR-3B is due on the 20th. QRMP quarterly filers have staggered deadlines (22nd or 24th depending on their state category).
  • CMP-08 Quarterly Due Date (18th) Composition scheme taxpayers must remit quarterly tax using CMP-08 by the 18th of the month following the quarter.
  • E-Way Bill Auto-Block for Non-Filers Failing to file GSTR-3B for two consecutive tax periods leads to automatic suspension of your GSTIN on the E-Way Bill portal.

Frequently Asked Questions

Official CBIC rules regarding due date extensions and late fees.

What happens if a GST due date falls on a Sunday or Public Holiday?

Under General Clauses Act and CBIC administrative practice, if the statutory due date falls on a public holiday or bank holiday, the effective due date moves to the immediately following working day. However, taxpayers are advised to file early to prevent portal congestion.

What is the difference between Category 1 and Category 2 states for QRMP GSTR-3B?

To balance GST portal server load, CBIC staggered QRMP GSTR-3B filings: Category 1 (Southern & Western states like Maharashtra, Gujarat, Karnataka, Tamil Nadu) file on the 22nd of the month following the quarter. Category 2 (Northern & Eastern states like Delhi, UP, Rajasthan, Haryana, West Bengal) file on the 24th.
