Finance Ministry Revises IGST Slabs for Inter-State Supplies Effective 22nd September 2025

The Ministry of Finance has revised Integrated Goods and Services Tax (IGST) slabs for inter-state supplies effective 22 September 2025, under the GST rate rationalisation. The new structure simplifies the multiple IGST rates to align with the central reforms: two main slabs (5% and 18%) for most goods and services. This reform will affect suppliers and businesses operating across state borders or involved in interstate supply chains. The changes are intended to reduce compliance complexity, harmonize tax burden across states, and discourage arbitrage between jurisdictions.
