For intra-state sales, GST is divided equally between CGST and SGST.
Example: An 18% GST rate is split into 9% CGST and 9% SGST.
Suppose the product price is ₹10,000 and the applicable GST rate is 18%.
For intra-state transactions:
Multiply the original amount by 18 and divide by 100.
CGST is collected by the Central Government, while SGST is collected by the State Government.
