COMMON QUESTIONS

Frequently Asked Questions

Understanding Goods and Services Tax splits
? What is GST?
GST (Goods and Services Tax) is a destination-based, multi-stage tax levied on the supply of goods and services, replacing multiple indirect taxes.
? What is the difference between CGST, SGST, and IGST?
CGST (Central) and SGST (State) are collected on transactions within a single state. IGST (Integrated) is collected on interstate transactions.
? How do I add GST to a base product price?
Formula: GST Amount = (Base Price * GST%) / 100. Total Price = Base Price + GST Amount.
? How do I remove/extract GST from a gross amount?
Formula: GST Amount = Gross Price - [Gross Price * (100 / (100 + GST%))]. Base Price = Gross Price - GST Amount.
