Short answer: GSTR-3B and GSTR-1 cost ₹50 a day late (₹25 CGST + ₹25 SGST), or ₹20 a day for a nil return. The fee stops at a cap set by turnover: ₹500 for nil returns, then ₹2,000, ₹5,000 or ₹10,000. Tax paid late also attracts 18% interest a year.
Late fee for GSTR-3B and GSTR-1
Since the June 2021 tax period, both returns use the same daily rate and the same caps per return (Notifications 19/2021 and 20/2021).
| Your case | Fee per day | Maximum per return |
|---|---|---|
| Nil return | ₹20 (₹10 + ₹10) | ₹500 |
| Turnover up to ₹1.5 crore | ₹50 (₹25 + ₹25) | ₹2,000 |
| ₹1.5 crore to ₹5 crore | ₹50 | ₹5,000 |
| Above ₹5 crore | ₹50 | ₹10,000 |
Turnover here means aggregate turnover in the previous financial year. The fee is split equally between CGST and SGST. For an inter-state supplier, the IGST portion works out to the same total.
Late fee for GSTR-4 and GSTR-9
From FY 2022-23 the annual returns have their own rules (Notification 7/2023).
| Return | Fee per day | Maximum |
|---|---|---|
| GSTR-4 (composition) | ₹50 (₹20 if nil) | ₹500 if nil, otherwise ₹2,000 |
| GSTR-9, turnover up to ₹5 crore | ₹50 | 0.04% of turnover in the state |
| GSTR-9, ₹5 crore to ₹20 crore | ₹100 | 0.04% of turnover in the state |
| GSTR-9, above ₹20 crore | ₹200 | 0.5% of turnover in the state |
GSTR-9 is optional for taxpayers with turnover up to ₹2 crore, so there is no late fee for them if they choose not to file.
Interest on late payment
Section 50 of the CGST Act charges 18% a year on tax paid late. It runs from the day after the due date to the day of payment, and only on the part paid in cash. Tax settled from input tax credit doesn't attract it.
A worked example
A client with ₹80 lakh turnover files GSTR-3B for September on 9 November instead of 20 October, paying ₹1,00,000 in cash.
- Days late: 20 (21 October to 9 November).
- Late fee: 20 × ₹50 = ₹1,000, under the ₹2,000 cap.
- Interest: ₹1,00,000 × 18% × 20 ÷ 365 = ₹986.
- Total: about ₹1,986, paid in cash.
How CA firms avoid it
Most late fees come from documents arriving late, not from the filing itself. Firms that stay clear of them track every client's due date in one place and chase documents a week ahead. Our due-date calendar lists every GST and TDS deadline for the next 60 days, and can send them to you on WhatsApp each Monday.
Standard rules as of November 2026. Waivers, amnesty schemes and portal changes override them, so check the GST portal before you file.
