How It Works: IGST Calculator

Integrated Goods and Services Tax (IGST) is administered by the Central Government under the IGST Act 2017. It applies to all interstate transactions (where the supplier and place of supply are in different Indian states) as well as international imports and Special Economic Zone (SEZ) supplies. Unlike intra-state trade, IGST is not split into halves on the invoice.

Formula & Calculation Methodology

IGST Amount = (Interstate Taxable Base × IGST Rate) / 100
Total Interstate Invoice = Taxable Base + IGST Amount

Notice: Designed to provide accurate results based on the standard formulas described above.
