  • Late fee is ₹25 CGST + ₹25 SGST per day (₹10 + ₹10 for a nil return), capped by aggregate turnover.

How GST late fee works

Late fee accrues per day from the day after the due date until filing: ₹50 per day (₹25 CGST + ₹25 SGST) for a normal GSTR-3B or GSTR-1, ₹20 per day for a nil return, capped according to your aggregate turnover in the previous financial year.

Interest is separate

If tax was payable, interest at 18% per annum runs on the net cash liability from the due date until payment. It is not capped and is computed on the actual days of delay.

Annual and final returns

GSTR-9 attracts ₹50–₹200 per day depending on turnover, capped at a percentage of turnover; GSTR-10 (final return after cancellation) attracts ₹200 per day up to ₹10,000.

Never pay a late fee again — our yearly GST plan files every return before its due date.

Indicative calculation under current rules; the GST/MCA portal computes the final amount at filing. Not professional advice.

Frequently asked questions

Is GST late fee charged on a nil return?↓

Yes — ₹20 per day (₹10 CGST + ₹10 SGST), capped at ₹500 per return under current rules.

How is interest calculated if I filed late but had input tax credit?↓

Interest applies on the portion of tax paid through the electronic cash ledger after the due date, not on the part settled with input tax credit.

Can late fees be waived?↓

Only under specific amnesty notifications issued by the government from time to time. Otherwise the portal auto-computes and collects the fee with the next return.

Where is the late fee paid?↓

It is auto-populated in the next GSTR-3B and must be paid before that return can be filed. Interest is self-assessed and paid through the same return or DRC-03.
