How is the GST Late Fee Calculated?
When you miss the deadline for filing your GST returns (like GSTR-1 or GSTR-3B), the government imposes two types of penalties: a daily late fee and an annual interest rate on the unpaid tax amount.
1. Daily Late Fee
- Normal Returns: ₹50 per day of delay (₹25 CGST + ₹25 SGST).
- Nil Returns: ₹20 per day of delay (₹10 CGST + ₹10 SGST). A Nil return means you had zero sales and zero purchases during the month.
2. Interest on Late Payment (Section 50)
If you have a tax liability (you owe tax to the government), you must also pay interest at 18% per annum. This interest is calculated only on the net tax liability paid in cash (after deducting Input Tax Credit).
Example Calculation
Suppose your GSTR-3B was due on 20th July, but you filed it on 25th July (5 days late). Your net tax liability was ₹10,000.
• Late Fee: 5 days × ₹50 = ₹250
• Interest: ₹10,000 × 18% × (5 / 365) = ₹24.65
• Total Penalty: ₹250 + ₹24.65 = ₹274.65
Assumptions & Methodology
- Calculation logic: Computes late fee based on days delayed. Normal returns calculate at ₹50/day. Nil returns calculate at ₹20/day.
- Interest rules: Interest is calculated at exactly 18% per annum, applied strictly to the unpaid net tax liability entered by the user. Formula:
Net Tax Liability × 18% × (Days Delayed / 365). - Limitations & Maximum caps: The calculator does not currently cap the maximum penalty based on aggregate turnover (e.g., ₹2,000 / ₹5,000 / ₹10,000 limits depending on AATO). It outputs the uncapped calculation for standard days delayed.
- Sources: Calculations are based on Section 47 (Late Fee) and Section 50 (Interest on delayed payment) of the CGST Act, 2017, as well as notifications issued by the Central Board of Indirect Taxes and Customs (CBIC).
