Understanding GST

What GST Is

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

GST rates determine the percentage of tax levied on a product or service according to its HSN/SAC statutory classification.

CGST, SGST & IGST

Intra-state sales split into CGST (Centre) and SGST (State). Inter-state sales and imports attract Integrated GST (IGST) in full.

Exclusive vs Inclusive

GST-exclusive means tax is added to the base price. GST-inclusive means the price tag already incorporates the tax amount.
