Section 9 – Levy and Collection of Tax

1. Statutory structure of Section 9

Section 9 is the principal charging provision for Central Goods and Services Tax on intra-State supplies. It establishes the ordinary levy and then creates separate statutory mechanisms for supplies where the recipient, rather than the supplier, is made liable for tax.

2. Section 9(1) – ordinary CGST levy

The ordinary rule is that CGST is charged on an intra-State supply of goods, services or both. Section 9 therefore works together with the IGST Act's place-of-supply provisions and the State/UT GST legislation. A transaction cannot be analysed under section 9(1) in isolation from the question of whether the supply is intra-State.

What the provision does

• Creates the charge of CGST.
• Applies to intra-State supplies of goods, services or both.
• Uses the value determined under section 15.
• Allows the Government to notify rates on the recommendation of the GST Council, subject to the statutory maximum of 20% for CGST.
• Places the normal tax liability on the taxable person unless another statutory mechanism shifts liability.

Important exclusions from the charge

Alcoholic liquor for human consumption remains outside the CGST levy. A significant later amendment was made in 2024: the exclusion was expanded to cover un-denatured extra neutral alcohol (ENA) or rectified spirit used for manufacture of alcoholic liquor for human consumption. This amendment took effect from 1 November 2024. citeturn1search5turn1search6

Rate ceiling versus actual notified rate

The words “not exceeding twenty per cent” are a statutory ceiling. They do not mean that every supply is taxable at 20% CGST. The actual rate depends upon the relevant rate notification and the classification of the supply.

3. Section 9(2) – petroleum products

Section 9(2) creates a special statutory mechanism for five specified petroleum products:

The provision is therefore different from a permanent exemption. It preserves a statutory route for these products to be brought within the CGST levy from a future notified date.

4. Section 9(3) – notified reverse charge

Section 9(3) is the first major reverse-charge mechanism under the CGST Act. Normally the supplier is liable to pay GST. Under section 9(3), the Government may notify particular categories of supplies where the recipient becomes liable.

The power is implemented through notifications rather than by treating every inward purchase as reverse charge.

Key notification framework

The GST Council's audit manual describes section 9(3) as the statutory basis for notified categories of goods or services on which tax is paid by the recipient and identifies Notifications 04/2017-CT(Rate) and 13/2017-CT(Rate) as the principal goods/services notification framework. citeturn0search8

Common examples in professional practice

• Specified legal services received from advocates, subject to the applicable notification conditions.
• Specified services received from a director by a company or body corporate, where the RCM notification applies.
• Specified GTA services, subject to the conditions and recipient categories in the relevant notification.
• Other notified goods/services such as those appearing in the periodically amended RCM schedules.

5. Section 9(4) – supplies from unregistered suppliers

Section 9(4) has undergone an important structural change. The original provision broadly contemplated tax on supplies received by a registered person from an unregistered supplier. That broad formulation was suspended and later replaced by a narrower enabling provision under which the Government may notify both the relevant class of registered persons and the relevant supplies.

The GST Council's 28th meeting agenda expressly records the proposed restructuring of section 9(4), replacing the broad mechanism with an enabling power to notify a class of registered persons and specified supplies. citeturn0search1

Real-estate sector application

Notification No. 07/2019-Central Tax (Rate), dated 29 March 2019, was issued under section 9(4) for specified supplies received from unregistered suppliers by promoters of real-estate projects. The notification became effective from 1 April 2019. citeturn2search0turn2search1

The framework includes specified construction-related procurement and other categories/conditions applicable to promoters, including mechanisms relating to shortfall in prescribed procurement, cement and certain capital goods. The precise liability must be tested against the notification and the project's facts rather than by applying a blanket “all purchases from unregistered persons” rule.

6. Section 9(5) – electronic commerce operators

Section 9(5) shifts tax liability to an electronic commerce operator for notified categories of services supplied through the operator. This is conceptually different from TCS under section 52: section 9(5) makes the ECO itself liable to pay the GST for the specified supply.

Original notified categories and later expansion

Notification No. 17/2017-Central Tax (Rate), dated 28 June 2017, implemented the section 9(5) mechanism. The notified framework has subsequently been amended. It has covered specified passenger transportation, accommodation and housekeeping-type services, with conditions relating to the supplier's registration status. citeturn2search32

More recent amendments have materially expanded the practical scope. Notification No. 08/2025-Central Tax (Rate), dated 16 January 2025, amended Notification 17/2017 following the 55th GST Council recommendations, including changes around specified-premises treatment for accommodation. citeturn2search13

Further, Notification No. 17/2025-Central Tax (Rate), dated 17 September 2025, added local delivery services, subject to the stated registration condition, with effect from 22 September 2025. citeturn2search9

Section 9(5) is not the same as TCS

Circular No. 240/34/2024-GST dated 31 December 2024 clarified the ITC treatment for ECOs making supplies under section 9(5), including that the section 9(5) tax liability is to be discharged through the electronic cash ledger and the related ITC cannot be used to discharge that liability. citeturn0search9turn0search2

7. Major amendment and development timeline

8. GST Council and policy background

Section 9 is one of the provisions where the role of the GST Council is visible throughout the operating framework. The Act repeatedly requires Government action on the Council's recommendations for rates and notified categories.

• Early GST Council framework: the original levy and reverse-charge architecture was developed as part of the transition to GST and the Council's recommendations on the charging and collection structure.
• 28th GST Council: the Council agenda recorded the restructuring of section 9(4), moving away from the broad registered-person RCM model towards a notification-based specified-class approach. citeturn0search1
• Later Council recommendations: RCM notifications have repeatedly been amended as sectors and transaction models evolved.
• 54th GST Council: the Council material discussed changes to GSTR-3B payment reporting to provide separate reporting for RCM supplies and section 9(5) supplies, illustrating the continuing distinction between the two mechanisms. citeturn0search4
• 55th GST Council: subsequent changes to the section 9(5) notification framework were implemented through Notification 08/2025-CT(Rate). citeturn2search13

9. Practical examples for businesses

Example 1 – ordinary intra-State purchase

A registered company buys taxable machinery from a registered supplier in the same State. The transaction is an intra-State supply. The supplier ordinarily charges CGST + SGST, subject to the applicable rate and other conditions. Section 9(1) is the charging basis for the CGST component.

Example 2 – advocate's specified legal service

A company receives a legal service that falls within the notified RCM category under Notification 13/2017-CT(Rate). Instead of the advocate charging CGST as the normal supplier, the recipient discharges the applicable GST under the RCM framework. The accounting team should verify the exact entry, recipient status and notification conditions.

Example 3 – unregistered vendor does not automatically mean RCM

A normal manufacturing company buys office stationery from an unregistered small supplier. The fact that the supplier is unregistered does not by itself activate section 9(4). The team must identify whether the transaction falls within a notification issued under section 9(4).

Example 4 – promoter and unregistered supplier

A promoter receives a specified construction-related supply from an unregistered supplier. The transaction must be tested against Notification 07/2019-CT(Rate), including the project, recipient and supply conditions. If the notification applies, the promoter pays tax under section 9(4).

Example 5 – ride or delivery platform

An ECO facilitates a service falling within the notified section 9(5) category. The ECO may become the person liable to pay GST on that service, subject to the exact notification and supplier-registration conditions.

Example 6 – petroleum product

A business purchases high speed diesel. Section 9(2) identifies HSD as a product for which CGST is to commence from a separately notified date. Therefore, the GST analysis cannot be reduced to the ordinary section 9(1) rate mechanism.

10. Professional workflow for Section 9 analysis

1. Identify the supply: goods, services or both.
2. Determine the nature of supply: intra-State or inter-State.
3. Check section 9(1): is the supply within the ordinary CGST charge and is any statutory exclusion relevant?
4. Check section 9(2): if petroleum crude, HSD, petrol, natural gas or ATF is involved, verify the statutory commencement position.
5. Check section 9(3): search the current goods/services RCM notifications and all relevant amendments.
6. Check section 9(4): verify whether the recipient belongs to a notified class and whether the inward supply is notified.
7. Check section 9(5): where an ECO is involved, determine whether the service is specifically notified and whether the supplier-registration exception applies.
8. Determine the rate: use the applicable rate notification rather than the 20% statutory ceiling.
9. Determine valuation: apply section 15 and any relevant valuation rules.
10. Record and report: ensure the liability is correctly reflected in the relevant GST returns, ledgers and tax-payment records.

11. Internal controls for accounts and tax teams

12. Common mistakes

• Treating every purchase from an unregistered supplier as section 9(4) RCM.
• Treating every service purchased through an online platform as section 9(5).
• Confusing section 9(5) liability with section 52 TCS.
• Using the 20% statutory ceiling as though it were the normal CGST rate.
• Ignoring the distinction between intra-State and inter-State supply.
• Applying an old RCM notification without checking subsequent amendments.
• Recording RCM in books but failing to ensure the tax is actually paid in the prescribed manner.
• Assuming that “outside GST” and “exempt supply” have exactly the same legal consequences.

13. Related provisions to read with Section 9

Section 9 is therefore best understood as part of a chain: supply → nature of supply → charge → applicable rate → person liable → valuation → payment → ITC → reporting.

14. Key takeaways

1. Section 9 is the principal CGST charging provision for intra-State supplies.

3. Section 9(2) creates a deferred levy mechanism for five specified petroleum products.
4. Section 9(3) is a notification-driven reverse-charge mechanism for specified supplies.
5. Section 9(4) is not a blanket RCM provision for every purchase from an unregistered supplier; it operates through notified classes and supplies.
6. Section 9(5) shifts liability to an ECO for notified services and has evolved significantly through later notifications.
7. RCM analysis must always be performed with the current notification and its amendments, not merely by reading the section in isolation.
