RCM GST CA Inter: Concept, Cases & Important Points for Sep 2026 Exam

For CA Inter Sept 2026, ICAI is increasingly testing GST through case-based questions, especially from RCM. Instead of direct theory, questions now require you to identify liability based on conditions, parties, and service type.

That’s why you must go beyond definitions and build clarity on “who pays GST in different real-life situations.” This chapter helps you quickly decode RCM cases and avoid common exam traps.

What is Reverse Charge Mechanism (RCM)?

The Reverse Charge Mechanism (RCM) is a GST provision where the recipient of goods or services pays tax directly to the government, instead of the supplier.

Before applying RCM, you must understand the default GST system.

In most transactions, GST follows a simple rule: The supplier collects and pays tax to the government.

However, for certain notified services, the government shifts this responsibility to the recipient to ensure better tax compliance and tracking.

This creates two parallel mechanisms in GST:

• Forward Charge Mechanism (FCM) – Default system

• Reverse Charge Mechanism (RCM) – Exception system

The table below highlights this fundamental difference clearly:

Forward Charge vs Reverse Charge

By default, GST follows the Forward Charge Mechanism, but the government applies RCM only to specific notified services.

Key Rule to Remember 

You should apply RCM only when all required conditions are satisfied, including:

• Nature of service

• Type of supplier

• Type of recipient

Applicability of RCM on Important Services

To apply RCM correctly in exams and practical scenarios, you must clearly understand which services are notified under GST and the specific conditions attached to each. The following list covers the most important and frequently tested services where RCM applies, along with their key rules and exceptions.

1. Sponsorship Services

You must apply RCM when:

• The recipient is a body corporate or partnership firm

• The service provider is not a body corporate

Example:
When a company sponsors an event, the company pays GST under the Reverse Charge Mechanism (RCM).

2. Services Provided by Directors

You should identify the nature of service first:

• Director fees are subject to GST under the Reverse Charge Mechanism (RCM).

•  Salary paid to a full-time director is treated as employment income and is not subject to GST.

•  Renting of property by a director to the company is treated as an independent service and is taxable under the Forward Charge Mechanism.

 Use TDS sections to differentiate:

• 194J → RCM

• 192 → Salary (No GST)

3. Insurance Agents and Recovery Agents

• Insurance company must pay GST under RCM on agent commission

• Banks must pay GST under RCM for recovery agent services

If a recovery agent provides services to a non-financial entity, apply Forward Charge instead.

4. Business Facilitator vs Business Correspondent

5. Security Services

Apply RCM when:

• The supplier is not a body corporate

• The recipient is a registered person

Do not apply RCM when services are provided to:

• Government departments

• Composition taxpayers

• TDS deductors

6. Goods Transport Agency (GTA)

GTA services attract GST under RCM in most cases.

• GST Rate under RCM → 5%

• Applicable to:

• Factories

• Registered persons

• Partnership firms

GTA can choose:

• RCM (5%) → No Input Tax Credit (ITC)

• Forward Charge (18%) → ITC available

7. Legal Services

• When an advocate provides services to a business entity, GST is payable under the Reverse Charge Mechanism (RCM).

• When an advocate provides services to an individual for personal use, such services are exempt from GST. 

8. Renting of Property

Residential Property

• When residential property is rented to a registered person, GST is payable under the Reverse Charge Mechanism (RCM).

•  When residential property is rented to an unregistered person, the service is exempt from GST.

Government Property

• When the government provides services to a business entity, GST is payable under the Reverse Charge Mechanism (RCM).

• When the government provides services to an unregistered person, GST is payable under the Forward Charge Mechanism. 

9. Import of Services

• When services are imported for business use, GST is payable under the Reverse Charge Mechanism (RCM).

• When services are imported for personal use, such imports are exempt from GST. 

OIDAR Services

• When such services are provided to a registered person, GST is payable under the Reverse Charge Mechanism (RCM).

•  When such services are provided to an unregistered person, the supplier is liable to pay GST under the Forward Charge Mechanism.

10. Motor Vehicle Renting

Apply RCM only if all conditions are satisfied:

1. Vehicle carries passengers

2. Supplier is not a body corporate

3. Recipient is a body corporate

4. Fuel cost is included

• GST Rate → 5% (No ITC allowed)

If any condition fails, apply Forward Charge.

11. E-Commerce Operators (Section 95)

E-commerce platforms must pay GST on certain services.

Examples include:

• Cab booking services

• Hotel booking platforms

• Delivery services

 In such cases, the platform (operator) pays GST instead of the service provider.

How to Identify RCM (Step-by-Step) 

Use a clear step-by-step method to quickly determine whether RCM applies in any GST question or practical case.

Step-by-Step (1-liners):

• Check whether the supply is notified under GST for RCM.

• Identify the type of supplier (individual, firm, company, etc.).

• Identify the type of recipient (registered, body corporate, etc.).

• Match all required conditions for RCM applicability.

• If conditions are satisfied, then apply RCM.

• If conditions are not satisfied, then apply the forward charge

Practical Examples: Cases of RCM 

• When a company receives sponsorship services from a non-body corporate, the company pays GST under the Reverse Charge Mechanism (RCM).

• When a bank hires a recovery agent for loan collection, the bank pays GST under RCM on the commission.

• When an advocate provides legal services to a business entity, the company pays GST under RCM.

• When a landlord rents residential property to an unregistered individual, GST is not applicable as the service is exempt.

• When a customer books a cab through an e-commerce platform, the platform (operator) is liable to pay GST under the applicable provisions.

The Reverse Charge Mechanism plays a crucial role in GST by shifting tax responsibility to the recipient for specific services. When you understand the conditions, applicability, and GST rates, you can easily solve exam questions and ensure proper tax compliance.
