How late fee and interest work

Late fee: a per-day fee under the CGST and SGST Acts for each delayed return, subject to a maximum. Interest: charged on tax paid late, at 18% per annum on the net tax liability (higher rate for certain ITC mismatches).

Reducing the damage

  • File nil returns on time; they are cheaper but still penalised.
  • Pay tax through the cash ledger as early as possible to stop interest.
  • Watch for government amnesty or relief notifications on late fees.
