Understanding GST Late Fees and Interest: The Basics

Let’s start with the fundamentals. GST late fees are penalties for missing return deadlines, while interest is charged separately for late tax payments. These are two different charges that can apply to your business, and understanding the distinction is crucial for accurate penalty calculation.

• GSTR-3B & GSTR-1: ₹50 per day (₹25 for CGST + ₹25 for SGST), capped at ₹5,000 per return
• Nil Return: ₹20 per day (₹10 for CGST + ₹10 for SGST), capped at ₹500

Interest Charges:

– 18% per annum for late GST payment
– 24% per annum if you’ve claimed excess Input Tax Credit (ITC)

For precise interest computations, use the GST interest calculator. To explore penalty structures in detail, visit the GST late fee interest penalties guide. For updated fee slabs, check the GST late fee 2025 updated rates rules penalty calculation.

Here’s a practical example to illustrate how these charges work:

If you’re filing GSTR-3B three days late:
Late Fee: ₹50 × 3 = ₹150 (₹75 CGST + ₹75 SGST)

If you’re filing a nil return three days late:
Late Fee: ₹20 × 3 = ₹60 (₹30 CGST + ₹30 SGST)
