What is GST?
GST stands for Goods and Service Tax. It is single, unified tax that replaced many old taxes in India, like VAT, service tax, excise duty. GST was introduced on 1st July 2017 with goal of making taxation simpler and more transparent. Before GST, same product could be taxed at different rates in different states, which created confusion for businesses and consumers. GST made tax system uniform across country, “one nation with one tax system”.
GST is consumption-based tax. This means tax is paid by person who buys and uses goods or services, not one who produces or sells them. Businesses collect GST from customers and pass it to government. They can also claim refund (Input Tax Credit) for GST they paid on purchases.
Types of GST in India
India’s GST is dual GST system. For intra-state sales (within same state) tax is split into CGST (central GST) and SGST (state GST) each getting half. For inter-state sales (between states), whole tax is collected as IGST (Integrated GST).
Tax slabs for goods & services tax
A tax slab is rate of tax applied to different types of goods and services. Under GST not all items are taxed at same rate; instead they are divided into categories and each category has specific tax percentages.
Latest Update (effective from 1 April 2026) From 1 April 2026 GST system has been updated and has changes in GST rules 2026 to make system simpler and more structured. GST had multiple slabs such as 0%, 3%, 5%, 12%, 18% and 28%. Under revised structure, GST tax rates are now 0%, 5%, 18% and 40%.

GST calculation formula
Exclusive GST Add GST to Original Price
Example
CGST (9%)
₹90.00
SGST (9%)
₹90.00
Inclusive GST Remove GST from Total Price
Original Price
= ₹1,180 × 100 ÷ (100 + 18)
= ₹1,180 × 100 ÷ 118
= ₹1,000
GST Amount
= ₹1,180 − ₹1,000
= ₹180
