Frequently asked questions
What's the difference between CGST, SGST, and IGST?
For intra-state transactions, GST is split equally into CGST (Central) and SGST (State). For inter-state transactions, IGST (Integrated) applies at the full GST rate.
How is GST calculated on an inclusive amount?
GST amount = Original Amount × Rate / (100 + Rate). The base price is the original amount minus the GST amount.
Which GST rate should I use?
5% for essential goods and food. 12% for processed foods and computers. 18% for most services and electronics. 28% for luxury goods, automobiles, and tobacco.
