Read this before you rely on a date
- These are the standard statutory dates. The government sometimes extends a date for one period or one state by notification. Always confirm on the CBIC or GST portal notifications before the deadline.
- A due date that falls on a Sunday or a holiday is not moved forward. File before it.
- GSTR-3B for QRMP filers falls on the 22nd (Category X states) or the 24th (Category Y states). Category X: Chhattisgarh, Madhya Pradesh, Gujarat, Maharashtra, Karnataka, Goa, Kerala, Tamil Nadu, Telangana, Andhra Pradesh, Daman and Diu, Dadra and Nagar Haveli, Puducherry, Andaman and Nicobar, Lakshadweep. Every other state and union territory is Category Y.
- Late filing costs money. Work out the exact amount with the GST late fee and interest calculator.
