What is GST?
GST (Goods and Services Tax) is an indirect tax levied on the supply of goods and services in India. It replaced multiple indirect taxes like VAT, service tax, and excise duty.
What is the difference between CGST and SGST?
CGST (Central GST) goes to the central government and SGST (State GST) goes to the state government. Together they make up the total GST. For example, 18% GST = 9% CGST + 9% SGST.
How to calculate GST on ₹10,000 at 18%?
GST amount = ₹10,000 × 18/100 = ₹1,800. Total price with GST = ₹10,000 + ₹1,800 = ₹11,800. CGST = ₹900, SGST = ₹900.
