What Is GST?

GST (Goods and Services Tax) is a destination-based indirect tax levied on the supply of goods and services. It is applicable across India and is categorized into:

• CGST (Central GST) – Collected by the Central Government

• SGST (State GST) – Collected by the State Government

• IGST (Integrated GST) – Collected on interstate transactions

GST eliminates cascading taxes and ensures transparency across the supply chain.
