Frequently Asked Questions

Everything about GST and Indian taxation.

What is GST?

GST (Goods and Services Tax) is a single indirect tax levied on the supply of goods and services in India. It replaced multiple taxes like VAT, service tax, and excise duty on 1 July 2017. GST is collected at every stage of the supply chain but is ultimately borne by the end consumer.

What are the GST slabs in India?

GST has 4 main slabs: 5%, 12%, 18%, and 28%. There are also special rates for specific categories: 0% (essential items like fresh food), 0.25% (rough precious stones), and 3% (gold and jewellery).

What is the difference between CGST, SGST, and IGST?

Intra-state sales (within the same state): GST is split equally into CGST (Central GST — goes to central government) and SGST (State GST — goes to state government).

Inter-state sales (between states): IGST (Integrated GST) is charged at the full rate and collected by the central government.

What is reverse GST calculation?

Reverse GST (also called "GST inclusive") is when you have the final price that already includes GST, and you want to find the base price and GST amount. Our "Remove GST" mode does this:

Base = Total ÷ (1 + GST Rate/100)

What is Cess and when is it applicable?

Cess is an additional tax charged on top of GST for certain "sin" or luxury goods like tobacco, aerated drinks, coal, cars, and pan masala. Cess rates vary from 1% to 290% depending on the product.
