Every day counts
The late fee keeps running until the return is filed, and a return cannot be filed while an earlier one is pending. Late fee is paid in cash only (input tax credit cannot be used). Caps: ₹500 for a nil return; otherwise ₹2,000, ₹5,000 or ₹10,000 by last year's turnover.How it is worked out
- Late fee: Rs 50 a day (Rs 25 CGST + Rs 25 SGST), or Rs 20 a day (Rs 10 + Rs 10) for a nil return, from the day after the due date to the day of filing.
- Caps by last year's turnover: Rs 2,000 up to Rs 1.5 crore, Rs 5,000 up to Rs 5 crore and Rs 10,000 above; Rs 500 for a nil return (CGST notifications 19/2021 and 20/2021).
- Interest: 18% a year on the net tax paid late in cash with GSTR-3B, for the days of delay. GSTR-1 carries no tax and so no interest.
- IGST returns and annual returns (GSTR-9) follow other rules and are not worked out here.
