How Interest Is Calculated

  • Interest under section 50 of the CGST Act is charged at 18% per annum on tax paid after the due date.
  • Interest is calculated day by day: Tax × 18% × days of delay ÷ 365.
  • Interest applies on the part of tax paid in cash through the electronic cash ledger. Tax paid by using input tax credit generally does not attract interest under the proviso to section 50(1).
  • Late fee is paid in cash and cannot be paid from the input tax credit balance.
