Petrol, diesel and alcohol are outside GST.
For intrastate (within same state) transactions: GST splits as CGST (Central GST) + SGST (State GST), each at half the rate. For interstate (different state) transactions: IGST (Integrated GST) at full rate applies. Total tax amount is the same in both cases.
GST Amount = Base Price x GST Rate. Example: ₹10,000 base at 18% = ₹1,800 GST; Total = ₹11,800. CGST = ₹900, SGST = ₹900 for intrastate supply.
Base Price = Inclusive Price / (1 + GST Rate). GST = Inclusive Price - Base Price. Example: ₹11,800 inclusive at 18%: Base = ₹11,800/1.18 = ₹10,000; GST = ₹1,800.
Businesses with annual turnover above ₹40 lakh (goods) or ₹20 lakh (services) must register for GST. For Northeast and special category states, threshold is ₹20 lakh (goods) and ₹10 lakh (services). Composition scheme available up to ₹1.5 crore.
