GST has a standard name in every Indian language, and these cards show the commonly used terms.
Why the tax on your bill used to be so confusing
GST is Goods and Services Tax, the indirect tax that came into force across India on 1 July 2017. Before that, a single product could pick up excise duty at the factory, VAT in one state, octroi at a city gate and a service tax on top.
Moving a truck from one state to another meant stopping at check posts and filling in different forms in each state, which cost time and money. One national tax with a common set of rules removed much of that, though GST has its critics too, especially over paperwork for small traders.
How the tax moves down the chain
GST is charged at every stage, from the maker to the wholesaler to the shop, but each business gets credit for the tax it already paid on its purchases. Only the final customer carries it in the end. That credit is called input tax credit.
It is also destination-based, so the tax goes to the state where the goods are consumed, not where they were made. Say you order a phone online in Hyderabad from a seller in Gurugram. The tax belongs to Telangana, not Haryana.
Inside a state, GST on a sale splits into CGST and SGST. Across states, it is charged as IGST.
A worked example with a bill
A shop in Pune buys goods for ₹10,000 and pays ₹1,800 GST at 18%. It sells them to you for ₹12,000 and charges 18% GST, which is ₹2,160. The shop sets off the ₹1,800 it already paid and deposits the remaining ₹360 with the government.
You paid ₹2,160 in GST in all, and the government received it in two instalments, ₹1,800 from the supplier earlier and ₹360 from the shop. Because the sale is inside Maharashtra, the ₹2,160 is split equally into CGST and SGST of ₹1,080 each.
As a customer you can check the rate shown against the item on the invoice, and you should receive a tax invoice with the supplier's GSTIN, the HSN or service code, the taxable value and the tax amount split into its components. Restaurants, for example, often charge a fixed rate that cannot be changed by adding service charge as GST, so ask if something looks wrong.
Rates, and why you should not trust an old list
For years GST had slabs of 0%, 5%, 12%, 18% and 28%, plus special rates such as 3% on gold, and a compensation cess on items like cars, tobacco and aerated drinks.
The GST Council approved a major rate rationalisation in September 2025, and the changes took effect from 22 September 2025. The main rates became 5% and 18%, with a higher rate of 40% for a small set of luxury and sin goods. Many everyday items moved to a lower rate.
Rates keep being revised, so a WhatsApp forward with a table is probably out of date. For anything you are billing or paying, use the official GST portal or ask your CA.
Registration, returns and the small business owner
A business must register for GST once its yearly turnover crosses the threshold set for its type and state, and some businesses, such as those selling across state lines or through certain e-commerce platforms, must register regardless. After registration you receive a 15-digit GSTIN and file periodic returns online.
Very small businesses can opt for the composition scheme, which means paying a low flat percentage of turnover with simpler returns, but they cannot pass on credit to customers. Whether it suits you depends on your customers, so ask an accountant before choosing.
How the law came together
The idea took a long time. Reform of indirect taxes began in 1986 with MODVAT, introduced when V. P. Singh was finance minister. Governments of different parties worked on it over the years, and a committee headed by West Bengal's finance minister Asim Dasgupta helped shape an early model.
It needed the 101st Amendment to the Constitution. Today the rules are decided by the GST Council, made up of the Union finance minister and the finance ministers of all the states. 1 July is observed as GST Day.
If you run a small business, ask your accountant whether you need registration and which return you have to file. If you are a customer, take a bill with a valid GSTIN for anything you may want to claim or return later.

How can I check if a GSTIN is genuine?
