Frequently Asked Questions
Goods and Services Tax (GST) is a unified indirect tax system in India that replaced multiple cascading taxes. It is levied on the supply of goods and services at each stage of the supply chain providing seamless input tax credit.
India has 4 main GST slabs: 5% (essential items), 12% (standard goods), 18% (most services and goods), and 28% (luxury items). Some items like unprocessed food, healthcare, and education are exempt (0% GST).
CGST (Central GST) and SGST (State GST) are levied on intra-state supplies - the tax amount is split equally between central and state. IGST (Integrated GST) is levied on inter-state supplies and is collected by the central government.
To add GST: Total Amount = Original Amount × (1 + GST Rate/100). For example, if an item costs ₹1000 and GST is 18%, total = ₹1000 × 1.18 = ₹1180.
To remove GST: Original Amount = Total Amount ÷ (1 + GST Rate/100). For example, if total is ₹1180 with 18% GST, original = ₹1180 ÷ 1.18 = ₹1000.
Businesses with annual turnover exceeding ₹40 lakhs (₹20 lakhs for special category states) must register for GST. The tax is ultimately borne by the end consumer, while businesses collect and remit it to the government.
ITC allows businesses to reduce the GST they owe on sales by the amount of GST they've already paid on purchases. This prevents tax cascading and reduces the overall tax burden throughout the supply chain.
Essential items like fresh fruits/vegetables, milk, eggs, bread, and services like healthcare, education, and public transport are GST exempt. Petroleum products are currently outside the GST regime.
