Frequently Asked Questions
What is GST? +
GST (Goods and Services Tax) is a single tax on goods and services in India, replacing many older taxes. It is charged at different rates: 5%, 12%, 18%, or 28% depending on the product or service.
What is the difference between "Add GST on top" and "GST already included"? +
"Add GST on top" means: the price shown does not include GST — you need to add it. Example: product costs ₹100 + 18% GST = ₹118 total. "GST already included" means: the price shown already includes GST — you want to find what the base price and tax amount are.
What is CGST and SGST? +
GST is split equally between Central Government (CGST) and State Government (SGST). So 18% GST = 9% CGST + 9% SGST. For interstate sales, it's IGST (full 18%) which goes to the central government and is then shared with the destination state.
Which products are taxed at 0% GST? +
Essential food items like fresh fruits, vegetables, milk, eggs, unprocessed cereals and pulses are taxed at 0% (nil rate). This keeps basic necessities affordable for everyone.
