GST Structure in Karnataka
When you make a sale within Karnataka (intra-state), the GST is split equally between CGST (Central GST) and SGST (Karnataka State GST). For example, on an 18% GST item:
- CGST: 9% goes to the Central Government
- SGST: 9% goes to Karnataka State Government
For inter-state sales (from Karnataka to another state), IGST (Integrated GST) of 18% is charged instead, which is later distributed between central and destination state governments.
