What is GST?

The Goods and Services Tax (GST), launched July 1, 2017, is India's unified indirect tax system that replaced 13+ different taxes including VAT, service tax, excise duty, entry tax, and Central Sales Tax. It is the most significant tax reform in India's history since Independence.

GST follows a destination-based consumption tax model — tax revenue goes to the state where the goods or services are consumed, not where they are produced. This eliminated the cascading tax effect (tax-on-tax) that made Indian goods globally uncompetitive.

Intra-state vs Inter-state: When buyer and seller are in the same state — GST splits into CGST + SGST (equally). When buyer and seller are in different states — full GST applies as IGST (goes to Centre, then shared with destination state).

GST for Business Owners — Key Rules

1

Registration threshold

Mandatory if annual turnover exceeds ₹40 lakh for goods (₹20 lakh for services, ₹10 lakh for special category states). E-commerce sellers must register regardless of turnover amount.

2

Composition Scheme (small businesses)

Businesses with turnover below ₹1.5 crore can pay flat 1–6% GST instead of standard rates. Simpler compliance, but cannot collect GST from customers or claim Input Tax Credit.

3

Input Tax Credit (ITC)

The most powerful GST benefit for businesses. GST paid on purchases can be set off against GST collected on sales. Only pay the net difference to government. Requires proper invoices from GST-registered suppliers.

4

Filing returns

Regular taxpayers file GSTR-1 (sales) monthly/quarterly and GSTR-3B (summary) monthly. Late filing penalty: ₹50/day (₹20/day for nil returns). Annual return GSTR-9 by December 31.

Frequently Asked Questions

From January 1, 2022, online food delivery platforms (Swiggy, Zomato) pay GST directly at 5% on restaurant meals ordered through their app. Previously, restaurants collected this GST. The change was made to improve compliance. So your Swiggy bill includes 5% GST collected by Swiggy, not the restaurant.
Residential rent is exempt from GST. Commercial rent (office space, shop) is subject to 18% GST if the landlord's total rental income exceeds ₹20 lakh per year. From July 2022, GST also applies on residential rent paid to a registered business or rented by a registered business, with the tenant able to claim ITC.
New cars attract 28% GST plus a Compensation Cess that varies by vehicle type: Small cars (sub-4m, petrol under 1200cc) — 28% + 1% cess. Mid-size petrol — 28% + 15% cess. SUVs and luxury cars — 28% + 22% cess. Electric vehicles — only 5% GST (significant incentive for EVs).
Generally, individuals cannot claim GST refunds — ITC and refunds are only for GST-registered businesses. However, tourists visiting India can claim refunds on goods purchased and taken out of India under the Tourist Refund Scheme, at designated refund counters at international airports.
