What Is the GST Late Fee?
filing a gst return after its due date attracts a late fee for every day of delay, plus interest on any tax you owe. the fee keeps accruing until the return is filed.
How It's Calculated
for gstr-3b: ₹50 per day (₹25 cgst + ₹25 sgst) for a return with turnover, or ₹20 per day for a nil return — subject to turnover-linked caps. interest of 18% per annum applies on the net tax paid late.
