GST FAQs

Frequently Asked Questions

1 What is GST?
GST (Goods and Services Tax) is an indirect tax applied on the supply of goods and services. It consolidates multiple domestic taxes (such as excise, service tax, VAT) into a single unified taxation framework.
2 What is the difference between GST Inclusive and Exclusive?
GST Exclusive refers to a price that does not yet include tax; GST must be added on top of this value. GST Inclusive means the quoted price already contains the tax amount, and the base price must be extracted from it.
3 How do you extract GST from an inclusive price manually?
To extract tax, use the formula: GST Amount = Price - (Price / (1 + (GST% / 100))). For example, if a product is $118 inclusive of 18% GST, the base price is 118 / 1.18 = $100, and the GST is $18.
4 What are CGST, SGST, and IGST?
CGST (Central GST) and SGST (State GST) are levied on intra-state transactions and are split equally (e.g. 18% GST splits into 9% CGST and 9% SGST). IGST (Integrated GST) is applied to inter-state sales and goes entirely to the central authority.
