Section 9 CGST Act explained: this guide covers what Section 9 CGST Act means, who it applies to, the step-by-step process, documents required, fees, due dates and penalties in India — so you can stay compliant with confidence and avoid costly mistakes.
Section 9 — Where the Tax Actually Gets Charged
Section 9(1) is the charging section of CGST: "There shall be levied a tax called the central goods and services tax on all intra-State supplies of goods or services or both" at the rate notified by the Government, not exceeding 20%, on the value determined under Section 15. This is the legal basis for the Central Government to collect CGST.
Section 9(1) — Forward Charge (Normal)
The default mechanism: the SUPPLIER charges CGST on their invoice and remits it to the government. The supply must be intra-state (within the same state). If inter-state, IGST applies under the IGST Act, not CGST.
Current rate structure: CGST is always half of the total GST rate. If total GST is 18%, CGST = 9% and SGST = 9%. Four main rate bands: 5% (CGST 2.5%), 12% (CGST 6%), 18% (CGST 9%), 28% (CGST 14%). Some goods at 0.25% (rough diamonds) and 3% (gold, silver). Some goods at 0% (essential food items, healthcare, education).
Maximum rate cap: 20% for CGST alone (i.e., combined CGST+SGST cannot exceed 40%). Currently, the highest actual rate is 28% (14% CGST + 14% SGST). Compensation cess adds further on luxury/sin goods (up to 22% on motor vehicles, up to 290% per unit on tobacco).
Section 9(3) — Reverse Charge Mechanism (RCM)
The tax liability shifts from the supplier to the RECIPIENT. The recipient must pay GST as if they were the supplier. RCM applies to two categories:
Category 1 — Notified goods/services: The Government notifies specific goods/services where recipient pays. Major RCM services:
| Service | Supplier | Recipient (Who Pays GST) |
|---|---|---|
| Legal services by advocate | Individual advocate/firm | Any business entity |
| GTA (Goods Transport Agency) | GTA not paying GST at 12% | Factory, society, company, partnership, AOP |
| Sponsorship services | Any person | Body corporate or partnership firm |
| Director services (non-employee director) | Director | Company or body corporate |
| Security services | Any person other than body corporate | Registered person |
| Renting of motor vehicle (non-body corporate) | Person other than body corporate | Body corporate |
| Insurance agent services | Insurance agent | Insurance company |
Category 2 — Supply by unregistered to registered (Section 9(4)): Originally, ANY supply by unregistered person to registered person attracted RCM. This was suspended almost immediately (too impractical). Currently limited to specified services like renting of residential dwelling by a registered person for business purposes (18% RCM from July 2022).
Section 9(5) — E-Commerce Operator Liability
For specified categories of services supplied through e-commerce operators (ECOs), the ECO is liable to pay GST (not the supplier). Currently applicable to:
(a) Transportation of passengers: Uber, Ola, Rapido — the platform pays GST on the ride fare.
(b) Accommodation services: OYO, MakeMyTrip — the platform pays GST on room bookings (if the hotel is not registered under GST).
(c) Restaurant services supplied through ECOs (from Jan 2022): Swiggy, Zomato — the platform pays GST at 5% on food delivery orders. The restaurant still files returns but the tax payment obligation is on the ECO.
Practical Calculations
Example 1 — Regular supply: Mumbai manufacturer sells goods to Mumbai retailer for Rs. 10 lakh. Intra-state. Rate: 18%. CGST = Rs. 90,000 (9%). SGST = Rs. 90,000 (9%). Manufacturer collects Rs. 11.80 lakh total, deposits Rs. 90K each as CGST and SGST.
Example 2 — RCM on legal services: Advocate provides legal opinion to a company in Chennai for Rs. 2 lakh. Advocate does not charge GST. Company pays Rs. 2 lakh to advocate AND pays GST Rs. 36,000 (18%) as RCM — Rs. 18K CGST + Rs. 18K SGST. Company immediately claims Rs. 36K as ITC. Net cash effect: zero (if done correctly in same month).
Example 3 — E-commerce restaurant: Customer orders food worth Rs. 500 on Zomato from a restaurant. Zomato collects Rs. 500 + Rs. 25 (5% GST) = Rs. 525 from customer. Zomato deposits the Rs. 25 GST. Restaurant receives Rs. 500 minus Zomato's commission. Restaurant does NOT collect/pay GST on this order — Zomato handles it.
