What is GST and Why Was It Introduced?
Before GST, India had a fragmented indirect tax system — businesses had to comply with VAT, excise duty, service tax, octroi, CST, and several other taxes. This created a "tax on tax" (cascading effect) problem and made interstate commerce complicated.
GST unified all these into one tax, introduced the concept of input tax credit (ITC) throughout the supply chain, and created a common national market. It launched on July 1, 2017 with the slogan "One Nation, One Tax."
Types of GST in India
| Type | Full Form | Collected By | When Applied |
|---|---|---|---|
| CGST | Central GST | Central Government | Intra-state sales (half of total GST) |
| SGST | State GST | State Government | Intra-state sales (half of total GST) |
| IGST | Integrated GST | Central Government | Inter-state sales (full GST rate) |
| UTGST | Union Territory GST | UT Administration | Sales within Union Territories |
Example: A Mumbai seller selling to a Pune buyer (intra-state) at 18% GST: CGST = 9% + SGST = 9%. Same seller selling to a Delhi buyer (inter-state): IGST = 18%.

Input Tax Credit (ITC) — The Key GST Concept
ITC is what makes GST different from the old cascading tax system. Businesses registered under GST can claim credit for the GST they paid on purchases (inputs), offsetting it against the GST they collect on sales (output).
Example: A manufacturer buys raw material for ₹1,000 + ₹180 GST (18%). They sell the product for ₹1,500 + ₹270 GST (18%). They already paid ₹180 GST on purchase. They only pay ₹270 − ₹180 = ₹90 net GST to the government. The ₹180 is their ITC.
This prevents the "tax on tax" problem — the government effectively receives GST only on the value added at each stage, not on the entire price repeatedly.
GST Registration — Who Needs to Register?
- Businesses with annual turnover above ₹40 lakh (goods) or ₹20 lakh (services) must register
- Special category states (northeastern states, Himachal Pradesh, Uttarakhand, J&K) have lower thresholds: ₹20 lakh (goods), ₹10 lakh (services)
- Regardless of turnover: Inter-state suppliers, e-commerce operators, casual taxable persons, and those required to pay under reverse charge must register
- Composition scheme: Small businesses under ₹1.5 crore turnover can opt for simplified taxation at 1–6% flat rate without ITC
GST for Consumers — What You Should Know
- MRP includes GST: By law, MRP on packaged goods includes all taxes including GST. A shop cannot charge more than MRP.
- Restaurant bills: AC restaurants charge 5% GST (no ITC). Check if restaurant has AC/non-AC designation before disputing the bill.
- E-commerce: GST is included in the price shown. No additional GST is charged at checkout for goods sold by Indian sellers.
- GST invoice rights: For any purchase above ₹200, you have the right to demand a GST-compliant invoice showing GSTIN, HSN code, and tax breakdown.
- Fake GST: If a shop shows a GST number on bill but it's fake, you can verify any GSTIN on gst.gov.in/verify-gstin.

Q: Is GST applicable on rent?
Residential rent is exempt from GST. Commercial property rent above ₹20 lakh/year attracts 18% GST. If you rent out a property to a GST-registered entity for commercial use, GST applies under reverse charge mechanism — the tenant pays GST, not the landlord.
Q: What is HSN code in GST?
HSN (Harmonised System of Nomenclature) is a 6-8 digit code used to classify goods under GST. Every goods invoice must mention the HSN code. Services use SAC (Service Accounting Code). Businesses with turnover above ₹5 crore must use 6-digit HSN codes; others can use 4-digit codes.
