FAQ

What is the CGST/SGST split?
For a sale within one state, GST is split equally into Central GST and State GST. For inter-state sales it's a single IGST at the full rate.
Which rate applies to my product?
Most goods and services are 18%. Essentials are 5%, and luxury or 'sin' goods are 28%. Check the CBIC rate finder for your HSN/SAC code.
