Questions people ask

What is the due date of GSTR-1?

The 11th of the next month if you file monthly. If you are in the QRMP scheme you file it once a quarter, by the 13th of the month after the quarter.

What is the due date of GSTR-3B?

The 20th of the next month for monthly filers. QRMP filers file it for the quarter by the 22nd or the 24th of the month after the quarter, depending on the state of their principal place of business.

Which states have the 22nd, and which the 24th?

The 22nd applies in Chhattisgarh, Madhya Pradesh, Gujarat, Maharashtra, Karnataka, Goa, Kerala, Tamil Nadu, Telangana and Andhra Pradesh, and in Dadra and Nagar Haveli and Daman and Diu, Puducherry, the Andaman and Nicobar Islands and Lakshadweep. The 24th applies in every other state and union territory.

What if a due date falls on a Sunday or a holiday?

Do not count on it moving. The GST portal charges late fee and interest from the day after the due date unless the government has notified an extension, so file a day early.

What happens if I file late?

A late fee is charged for each day of delay, and interest at 18% a year is charged on tax paid late. A late GSTR-1 also delays your customers’ input tax credit, because your invoices reach their GSTR-2B late.

Is there a time limit after which a return cannot be filed at all?

Yes. A GST return cannot be filed more than three years after its due date. The portal has enforced this since 01-08-2025.
