How GST late fee & interest work
Late fee: ₹50 per day of delay for a normal return (₹25 CGST + ₹25 SGST), or ₹20 per day for a nil return (₹10 CGST + ₹10 SGST), counted from the due date to the actual filing date.
Cap: the late fee is capped per return based on your turnover — commonly ₹2,000 (turnover up to ₹1.5 Cr), ₹5,000 (₹1.5–5 Cr) or ₹10,000 (above ₹5 Cr); nil returns are capped at ₹500.
Interest: 18% per annum on the net tax paid in cash, for the number of days delayed. Interest applies only where there is a tax liability.
This is an estimate to help you plan. GST rules and caps change and can vary by return type — always confirm the exact amount on the official GST portal before paying.
