How the late fee works
A delayed GSTR-3B attracts ₹50 per day where there is tax to pay — ₹25 CGST plus ₹25 SGST — and ₹20 per day for a nil return. The fee stops accruing at a ceiling that depends on your aggregate turnover, which is why a return filed a year late often owes far less than the day count suggests.
Interest is separate from the fee. It runs at 18% per annum on the tax actually outstanding, so a nil return accrues no interest however late it is.
Filing GSTR-1, 3B and the annual 9, and reconciling them against books, is the daily work of an accountant in India. It is also the part of the job that gets people hired. Our 45-day cohort covers it end to end on real data, with placement support.
