IGST = CGST + SGST

IGST is basically a combination of:

• SGST (State GST)

But instead of charging both separately, IGST is charged as a single tax on interstate transactions.

Key Features of IGST in GST System

IGST has some important features that make it easy for businesses to handle interstate transactions:

• It is charged when goods or services move from one state to another

• It combines both CGST and SGST into one tax
• It helps avoid double taxation
• It allows smooth flow of Input Tax Credit (ITC)

In short, IGST makes interstate business simple and transparent.
