What is GST?

The Goods and Services Tax (GST) is a comprehensive, multi-stage, destination-based tax that is levied on every value addition in India. It has largely replaced many indirect taxes in India such as the excise duty, VAT, and services tax.


How to Calculate GST

To calculate the final price you must charge a customer, you simply apply the appropriate GST slab rate (5%, 12%, 18%, or 28%) to your base product price.

CGST vs SGST vs IGST

If you are selling to a customer within your own state, the total GST is split equally into CGST (Central GST) and SGST (State GST). If you are selling to a customer in a different state, the entire amount is charged as IGST (Integrated GST). The total tax amount remains the same either way.
