Interest Rates for Delayed GST Payment

Standard Interest Rate

Interest on delayed GST payment is charged at 18% per annum under Section 50 of the CGST Act.

Higher Interest Rate

Interest Calculation Basis

Interest is calculated on the net cash tax liability (not on the ITC portion).

Late Fee Calculation Examples

Example 1: GSTR-3B Filed 10 Days Late (with Tax Liability)

  • Late fee: ₹50 Ɨ 10 = ₹500
  • Split: ₹250 CGST + ₹250 SGST

Example 2: GSTR-3B Filed 10 Days Late (Nil Return)

  • Late fee: ₹20 Ɨ 10 = ₹200
  • Split: ₹100 CGST + ₹100 SGST

Example 3: GSTR-9 Filed 30 Days Late

  • Late fee: ₹200 Ɨ 30 = ₹6,000
  • Split: ₹3,000 CGST + ₹3,000 SGST

Interest Calculation Examples

Example 1: Tax of ₹1,00,000 Paid 30 Days Late

  • Interest: ₹1,00,000 Ɨ 18% Ɨ 30/365 = ₹1,479

Example 2: Excess ITC Claim of ₹50,000

  • Interest: ₹50,000 Ɨ 24% Ɨ period = Higher interest applicable
