Frequently asked questions
What is inclusive GST?
The entered amount already contains GST, so the calculator extracts the taxable value and tax.
When is IGST shown?
Choose inter-state supply to show the entire GST amount as IGST.
What changed in GST rates from 22 September 2025?
GST rates were rationalised with effect from 22 September 2025, with 5% and 18% as the principal rates and a special 40% rate for specified supplies. Nil rates, exemptions and other applicable rates continue according to relevant notifications. Certain goods, including specified tobacco and pan masala products, followed a separate transition timetable. Always verify the applicable rate for the relevant goods or services and transaction date. The tax treatment of specified tobacco and pan masala products changed from 1 February 2026. Compensation cess is not assumed to continue on those products after its withdrawal. The cess position is determined separately. The withdrawal of GST compensation cess does not mean that no other applicable cess or levy may arise. Any separate levy must be checked under its own legal provisions.
