What is GST and How Does it Work in India?

GST โ€” Goods and Services Tax โ€” replaced a complicated web of central and state taxes (VAT, service tax, excise, octroi etc.) in July 2017. The idea was to create one unified tax across India. Whether you buy a phone in Mumbai or Jaipur, the GST on it is the same. Pretty straightforward in principle.

GST is a destination based tax โ€” meaning it goes to the state where the goods or services are consumed, not where they are produced. For most transactions within a state, you pay CGST (Central GST) + SGST (State GST), each being half the total rate. For interstate transactions, you pay IGST (Integrated GST) which equals the full rate.

GST Rate Slabs in India

India has multiple GST slabs โ€” 0%, 5%, 12%, 18%, and 28%:

0% (Exempt) โ€” Basic food items like fresh vegetables, milk, eggs, bread, salt, unprocessed grains. Also healthcare and education services.

5% โ€” Processed foods like frozen vegetables, packed paneer, coffee, tea. Also economy class air travel, transport services.

12% โ€” Business class air travel, processed foods like fruit juices, butter, cheese. Also construction of affordable housing.

18% โ€” This is the most common slab. Includes most services (restaurants, telecom, financial services), electronics, computers, IT services. Most of the things you buy day to day fall here.

28% โ€” Luxury and sin goods. Automobiles, tobacco, aerated drinks, casinos, five star hotels, cement. Also certain white goods.

Inclusive vs Exclusive GST โ€” The Difference

This trips up a lot of people. There are two ways a price can be quoted:

GST Exclusive (price without GST): The MRP shown does not include GST. Final price = MRP + GST amount. You see this mostly in B2B transactions or in quotes from contractors.

GST Inclusive (price with GST): The price shown already includes GST. To find the base price: Base = Total Price รท (1 + GST rate/100). You see this in retail โ€” when you buy a phone at โ‚น20,000, that price already includes GST.

GST Exclusive: GST Amount = Price ร— GST Rate / 100 Total Price = Price + GST Amount GST Inclusive: Base Price = Total Price / (1 + GST Rate/100) GST Amount = Total Price - Base Price

Input Tax Credit (ITC) โ€” Why Businesses Care So Much

One of the most important features of GST is Input Tax Credit. If you are a GST registered business, the GST you pay on your purchases (inputs) can be set off against the GST you collect on your sales (output). You only pay the net difference to the government.

Example: You manufacture furniture. You buy wood for โ‚น1,00,000 and pay 18% GST = โ‚น18,000. You sell furniture for โ‚น2,00,000 and collect 18% GST = โ‚น36,000. Your actual GST payable to government = โ‚น36,000 - โ‚น18,000 = โ‚น18,000. This prevents tax on tax and makes the system more efficient.

FAQs

Do small businesses need to register for GST?
Businesses with annual turnover above โ‚น40 lakh (โ‚น20 lakh for service providers, โ‚น10 lakh in special category states) must register for GST. Below this threshold, registration is optional. Small businesses can opt for the Composition Scheme if turnover is below โ‚น1.5 crore โ€” they pay a flat 1โ€“5% GST and have simpler compliance.
Why does restaurant GST differ so much?
Non-AC restaurants charge 5% GST (no ITC). AC restaurants also charge 5% GST. Hotels with room tariff above โ‚น7,500 per night charge 18% on food. Outdoor catering charges 18%. If you see a restaurant charging 18% GST, it is likely a hotel restaurant with high room rates. Always check your bill โ€” some places try to overcharge.
What is a GST invoice and why is it important?
A proper GST invoice must have the sellers GSTIN, invoice number, date, description of goods/services, HSN/SAC code, GST rate and amount (breakup of CGST/SGST or IGST). This invoice is essential for the buyer to claim Input Tax Credit. Always ask for a proper GST invoice for business purchases.
Is GST charged on second hand goods?
GST on second hand goods is charged only on the margin (difference between selling price and purchase price) for dealers. For individuals selling personal used goods (like on OLX), GST is generally not applicable. However registered dealers buying and reselling used cars, electronics etc. pay GST on margin.
