Understanding GST in India
The Goods and Services Tax (GST) is a comprehensive indirect tax introduced on 1st July 2017, replacing a complex web of central and state taxes including VAT, Service Tax, Excise Duty, and multiple cesses. Under the "One Nation, One Tax" vision, GST unified India's ₹200+ trillion economy into a single taxation framework, simplifying compliance for over 1.4 crore registered businesses. GST is a destination-based, multi-stage tax that is levied at every point of value addition in the supply chain, with input tax credit (ITC) ensuring that tax is effectively paid only on the final value added at each stage.
GST Tax Slabs Explained
India's GST framework uses a four-tier rate structure designed to balance revenue needs with affordability. The 5% slab covers household essentials like packaged food items, coal, economy rail travel, and basic footwear. The 12% slab applies to processed foods, business-class air tickets, frozen meat, butter, ghee, and mobile phones. The 18% slab — the most widely applicable rate — covers the majority of goods and services including electronics, IT services, restaurants (with ITC), capital goods, and most manufactured items. The 28% slab targets luxury and demerit goods such as automobiles, consumer durables (ACs, dishwashers), tobacco products, aerated drinks, and cement. Additionally, certain essential items like fresh fruits, vegetables, milk, and unprocessed grains are exempt from GST entirely (0%).
CGST vs SGST vs IGST
The type of GST levied depends on the nature of supply. For intra-state transactions (buyer and seller in the same state), the GST is split equally between the Central Government and the State Government — half goes as CGST (Central GST) and the other half as SGST (State GST) or UTGST for Union Territories. For example, an 18% GST intra-state means 9% CGST + 9% SGST. For inter-state transactions (buyer and seller in different states), a single IGST (Integrated GST) is levied at the full rate by the Central Government, which then settles the state's share. This mechanism ensures seamless credit flow across state borders while maintaining each state's revenue share.
FAQ
What is the difference between GST-inclusive and GST-exclusive pricing?
GST-exclusive pricing means the quoted price does not include GST — the tax is added on top of the listed price. For instance, an item priced at ₹1,000 with 18% GST exclusive costs ₹1,180 in total. GST-inclusive pricing means the quoted price already contains the GST component. In this case, a ₹1,180 GST-inclusive price at 18% means the base price is ₹1,000 and ₹180 is the tax. MRP (Maximum Retail Price) printed on consumer goods is always GST-inclusive, while B2B invoices often use exclusive pricing to allow clear ITC claims.
How do I know which GST slab applies to my product?
Every product and service in India is classified under an HSN code (Harmonized System of Nomenclature) for goods or an SAC code (Services Accounting Code) for services. These codes map directly to a specific GST rate. You can look up the correct code and rate on the official CBIC GST portal at cbic-gst.gov.in or use the GST Rate Finder app released by the government. For businesses with turnover above ₹5 crore, mentioning the 6-digit HSN code on invoices is mandatory; those below can use 4 digits.
