What is CGST?
Central GST (CGST) is the portion of GST collected by the central government on transactions that happen within a single state. It is always charged alongside an equal amount of SGST, so together they make up the full GST rate.
Example: On an 18% GST rate, CGST = 9% and SGST = 9%.
CGST at Common Rates

| 12% | 6% | 6% |
| 18% | 9% | 9% |
| 28% | 14% | 14% |
Frequently Asked Questions
No — CGST and SGST together make up the total GST rate for an intra-state sale; they aren't added on top of each other. An 18% GST rate is 9% CGST plus 9% SGST, not 18% + 18%.
For sales between two different states, IGST applies instead of CGST and SGST. Use the IGST Calculator for that scenario.
