Goods and Services Tax (GST) replaced a tangle of central excise, service tax, VAT, octroi, and entry taxes in July 2017. It is now the single indirect tax on almost everything you buy in India. While it has been several years since its launch, many consumers still find the breakup on their bills confusing. Here is a plain-English explanation of how GST works for you.
A Destination-Based Tax
GST is charged where the customer consumes the goods or service, not where the seller is located. If a Mumbai company sells software to a Bengaluru customer, the GST goes to Karnataka. This is why every invoice has a "place of supply" line.
CGST, SGST, IGST: The Three Components
When you buy something within your own state, the GST is split equally: - CGST (Central GST): Goes to the Central Government. - SGST (State GST): Goes to your State Government. - A ₹1,000 product at 18% GST shows ₹90 CGST and ₹90 SGST.
When you buy across states (e.g., ordering from Amazon from a different state), there is no split. The whole 18% becomes IGST (Integrated GST). This is just an accounting mechanism—for you, the customer, the total rate remains the same.
The Four Standard Rates in India
India has a four-tier GST structure: - 5%: Essentials like packaged food, footwear under ₹1,000, and economy air tickets. - 12%: Processed food items, mobile phones (historically), and business class tickets. - 18%: The default rate for most services and goods, including soaps, computers, telecom, and banking services. - 28%: Luxury and sin goods like cars, ACs, refrigerators, and tobacco. A "Cess" is often added on top for items like luxury cars.
Exempt Items: Fresh fruit, vegetables, milk, eggs, salt, and books are all GST-free. Education and healthcare services are also largely exempt.
Input Tax Credit (ITC): Why GST is Efficient
Before GST, taxes were "cascading" (tax on tax). A manufacturer paid tax on raw materials, and the retailer paid tax again on the final product without getting credit for the manufacturer's tax. Under GST, a business only pays tax on the value added. They can claim credit for the GST they paid to their suppliers. This "Input Tax Credit" system is designed to reduce the final price for the consumer by removing the tax-on-tax effect.
Reading a GST Invoice
A valid GST invoice for a consumer must show: 1. Seller's Name and GSTIN (15-digit number). 2. Date of Invoice and Serial Number. 3. HSN Code (for goods) or SAC Code (for services). 4. Taxable Value (Price before tax). 5. GST Rate (5%, 12%, 18%, or 28%). 6. GST Amount split into CGST/SGST or IGST. 7. Total Amount (including tax).
Always check the GSTIN format: It starts with a 2-digit state code (e.g., 27 for Maharashtra, 07 for Delhi), followed by the 10-digit PAN of the business. Use our GST calculator to verify the math on any invoice.
Common GST Traps for Consumers
- MRP includes GST: Packaged goods (like a bottle of Pepsi or a bag of chips) have an MRP printed on them. By law, no seller can charge GST on top of the MRP. The MRP is inclusive of all taxes.
- Restaurant Billing: AC restaurants usually charge 5% GST without Input Tax Credit. Some premium restaurants in 5-star hotels charge 18%. Service charge is NOT GST; it is a tip for the staff and is optional as per recent guidelines.
- E-commerce: When you see "Price includes GST" on a website, the seller is already factoring the tax. If they add it at checkout, ensure the total doesn't exceed the product's official MRP.
- Small Businesses: Businesses with a turnover below ₹40 Lakh (₹20 Lakh for services) are not required to register for GST. If they aren't registered, they cannot charge you GST.
GST on Real Estate
This is a common area of confusion for home buyers. - Under-construction flats: 5% GST (or 1% for affordable housing). There is no Input Tax Credit for the builder here. - Ready-to-move-in flats: 0% GST. If a project has received its Completion Certificate (CC), the builder cannot charge you GST. This is a huge saving for buyers. Use our Stamp Duty Calculator to see other costs associated with buying a home.
