Assumptions & scope

  • Rate options reflect the GST rate rationalisation effective 22 September 2025 (0%, 0.25%, 3%, 5%, 18%, 40%).
  • Intra-state supply splits the tax equally into CGST + SGST/UTGST; inter-state supply is charged as a single IGST.
  • The exact rate for a product or service depends on its HSN/SAC classification — always check the official rate finder.

Estimate only — not professional advice

This calculator gives an estimate based on the assumptions above and the figures you enter. It is not personalised tax advice. Verify with official sources (incometax.gov.in, the GST portal and Union Budget documents) and consider a qualified professional before acting.
