What are the GST rates in India?

India has 5 GST rate slabs: 0% (essential goods like fresh food, books), 5% (packaged food, medicine), 12% (processed food, electronics accessories), 18% (most goods and services, restaurants), and 28% (luxury goods, automobiles, tobacco).

What is the difference between CGST, SGST, and IGST?

For intra-state transactions (buyer and seller in the same state): CGST + SGST = Total GST, each being half the total rate. For inter-state transactions: IGST = Total GST rate. IGST is then split between central and destination state governments.

How do I calculate GST exclusive price from GST inclusive price?

GST-exclusive price = GST-inclusive price / (1 + GST rate/100). For example, if a product costs ₹1,180 with 18% GST, the base price = 1180 / 1.18 = ₹1,000.

How do I add GST to a base price?

GST-inclusive price = Base price × (1 + GST rate/100). For example, ₹1,000 with 18% GST = 1000 × 1.18 = ₹1,180.

Is GST applicable on exports?

No, exports are zero-rated under GST. Exporters can claim refund of input tax credit on zero-rated supplies.
