What is IGST?

IGST (Integrated Goods and Services Tax) is charged on inter-state supply of goods and services, i.e., when the buyer and seller are in different states. Unlike intra-state transactions where GST is split into CGST and SGST, IGST is charged as a single tax at the full rate.

Example: Seller in Maharashtra, Buyer in Gujarat — 18% GST:

IGST = 18% (full rate, not split)

On ₹1,000: IGST = ₹180

IGST is collected by the Central Government and then distributed to the destination state. It also applies to imports into India.
