How to Use
GST (Goods and Services Tax) is India's unified indirect tax that replaced multiple central and state taxes (VAT, excise, service tax, etc.) on July 1, 2017. Every product and service in India (except a few exempted items and petroleum) carries a GST rate.
GST 2.0 — The Biggest Overhaul Since 2017
At the 56th GST Council meeting, India simplified its rate structure from 5 slabs to 4 slabs, effective September 22, 2025. The old 12% and 28% slabs were abolished. Most 12% items moved to 5%, most 28% items moved to 18%, and a new 40% slab was created for sin goods and luxury items. Health and life insurance premiums became fully exempt (0%).
Understanding GST Types
CGST + SGST: For transactions within the same state, GST is split equally between Central GST and State GST. IGST: For inter-state transactions, Integrated GST is charged at the full rate. The total tax amount is the same — only the split differs.

ITC is the GST you paid on business purchases. You can subtract it from the GST you collect from customers and only pay the difference to the government. This prevents tax-on-tax (cascading effect).
