Frequently asked
What's the difference between CGST, SGST, and IGST?
For a sale within the same state, GST is split equally between CGST (central) and SGST (state). For a sale between two different states, the full amount is charged as IGST (integrated) instead.
Which GST rate should I use?
It depends on the goods or service. Most fall under 5%, 12%, 18%, or 28%. Check the applicable HSN/SAC code if you're unsure, or use the custom rate field.
Is this the same as the Reverse GST Calculator?
No. This tool adds GST to a base price. If you have a GST-inclusive price and want to find the base price, use the Reverse GST Calculator instead.
