❓ Frequently Asked Questions

What are the GST slabs in India?

▼

India has 5 GST slabs: 0% (essential goods like rice, milk), 5% (basic necessities, economy class travel), 12% (processed foods, medicines), 18% (electronics, most services, restaurants), 28% (luxury goods, cars, tobacco). The 18% slab covers the majority of goods and services.

What is GST exclusive vs inclusive?

▼

GST Exclusive: the stated price does not include GST. GST is added on top. A product priced at Rs 100 exclusive of 18% GST costs Rs 118 total. GST Inclusive: the stated price already includes GST. A product priced at Rs 118 inclusive of 18% GST has a base price of Rs 100 and GST of Rs 18.

What is the difference between CGST, SGST and IGST?

▼

CGST (Central GST) and SGST (State GST) are each half the total GST rate, applied on intra-state (within same state) transactions. IGST (Integrated GST) equals the full GST rate, applied on inter-state (different state) transactions. For 18% GST on intra-state: CGST = 9%, SGST = 9%. For inter-state: IGST = 18%.

How do I calculate GST on a price?

▼

Exclusive (add GST): GST Amount = Price x Rate / 100. Total = Price + GST Amount. Inclusive (extract GST): Base Price = Price / (1 + Rate/100). GST Amount = Price – Base Price. Example: Rs 1180 inclusive of 18% GST. Base = 1180/1.18 = Rs 1000. GST = Rs 180.

Who needs to register for GST?

▼

Businesses with annual turnover above Rs 40 lakh (goods) or Rs 20 lakh (services) must register for GST. Special category states have lower limits. E-commerce operators and inter-state suppliers must register regardless of turnover. Voluntary registration is allowed even below threshold.
