What is GST?

Goods and Services Tax (GST) is an indirect tax levied on the supply of goods and services in India. It's a comprehensive, multi-stage, destination-based tax that replaced multiple cascading taxes. GST is divided into CGST (Central GST), SGST (State GST), and IGST (Integrated GST) depending on whether the transaction is intrastate or interstate.

GST Rates in India

India follows a four-tier GST rate structure: 5%, 12%, 18%, and 28%. Essential items like food grains are taxed at 0%, while luxury and sin goods attract 28% GST. Most goods and services fall under the 18% tax slab.

IGST vs CGST + SGST

IGST (Integrated GST): Applied on interstate supplies (buyer and seller in different states). The entire GST amount goes to the central government, which then distributes it to states.

CGST + SGST: Applied on intrastate supplies (buyer and seller in the same state). The GST is split equally between the central government (CGST) and state government (SGST).
