What is IGST?
Integrated Goods and Services Tax (IGST) is a tax levied under the GST regime on the inter-state supply of goods and services (i.e., transactions occurring between two different states or union territories), as well as on imports and exports.
Unlike CGST and SGST, the entire tax revenue from IGST is collected by the Central Government and subsequently apportioned appropriately to the destination state.
How to use this calculator for IGST
Select the "Inter-State" transaction type within the calculator above. The tool will automatically compute the full tax percentage as IGST instead of splitting it into CGST and SGST components.
