Comprehensive Guide to Input Tax Credit (ITC) and Reverse Charge Mechanism (RCM) under GST

Meaning of Normal ITC and RCM ITC

1. Normal Input Tax Credit (ITC)

Definition: Normal ITC refers to the credit claimed by a registered taxpayer for the GST paid on inward supplies (goods or services) against the GST liability on outward supplies. This mechanism ensures that the tax burden is passed on to the end consumer, avoiding cascading effects of taxation.

Applicable Section: Section 16 of the CGST Act, 2017 outlines the eligibility and conditions for claiming ITC.

Invoice Requirements:

• A valid tax invoice issued by the supplier, as per Section 31(1) or Section 31(2).
• The supplier must have filed returns (e.g., GSTR-1, GSTR-3B) and paid the GST liability to the government.
• The recipient must receive the goods/services mentioned in the invoice.

Key Features:

• Supplier is responsible for collecting and remitting GST.
• ITC can be claimed as soon as the conditions specified under Section 16 are met.
• Reported in Table 4(A) of GSTR-3B as “Eligible ITC.”

2. Reverse Charge Mechanism (RCM) ITC

Definition: Under the Reverse Charge Mechanism (RCM), the recipient of goods or services is liable to pay GST directly to the government instead of the supplier. Once the GST is paid, the recipient can claim it as ITC, subject to the conditions specified in the GST laws.

Applicable Section: Section 9(3) and Section 9(4) of the CGST Act, 2017 specify cases where RCM is applicable.

Invoice Requirements:

• A self-invoice must be issued by the recipient under Section 31(3)(f) if the supplier is unregistered.
• The recipient must pay GST in cash before claiming ITC.
• Details must be reported in the GST returns as follows:
  • RCM liability in Table 3.1(d) of GSTR-3B.
  • ITC under RCM in Table 4(A)(3) of GSTR-3B.

Key Features:

• Recipient assumes the liability to pay GST.
• ITC can only be claimed after the recipient has discharged the RCM liability.
• Self-invoicing is mandatory for unregistered supplier transactions.

Examples of RCM Transactions:

• Legal services provided by an advocate.
• Supply of goods by an unregistered supplier.
• Notified goods/services such as tobacco leaves or renting of immovable property.

Blocked Credit: Goods or Services Ineligible for ITC

Section 17(5) of the CGST Act, 2017 lists specific goods and services for which Input Tax Credit (ITC) is blocked, meaning taxpayers cannot claim ITC on these items. Below is a comprehensive table outlining the categories of blocked credit:

Category	Description	Exceptions (Where ITC is Allowed)
Motor Vehicles	ITC on motor vehicles for personal use is blocked.	Vehicles used for transportation of goods. Vehicles used for taxable supplies like transportation of passengers or training on driving, flying, or navigation.
Food and Beverages	ITC is blocked for food, beverages, and outdoor catering.	If it is provided as part of a taxable composite or mixed supply.
Health and Life Insurance	ITC on health insurance, life insurance, and fitness services is blocked.	If mandated by law (e.g., worker safety compliance).
Membership of Clubs	ITC on membership fees for clubs, health, or fitness centers is blocked.	None
Travel Benefits	ITC is blocked for travel benefits extended to employees (e.g., leave or home travel).	If provided as a statutory obligation under employment laws.
Works Contract Services	ITC on works contract services for construction of immovable property (other than plant or machinery) is blocked.	If it is used as input service for providing works contract service.

Time Limits for Claiming ITC: Normal ITC vs RCM ITC

The eligibility to claim Input Tax Credit (ITC) is subject to specific time limits prescribed under the GST law. These time limits differ based on whether the ITC pertains to normal transactions or reverse charge mechanism (RCM). Below is a detailed explanation:

1. Time Limit for Normal ITC

The time limit for claiming ITC under **Normal ITC** is governed by Section 16(4) of the CGST Act, 2017. The law specifies that ITC for any invoice or debit note can only be claimed by the earlier of the following dates:

• 30th November of the subsequent financial year: For example, for an invoice dated 10th January 2023 (FY 2022-23), ITC must be claimed by 30th November 2023.
• Date of filing the annual return: The annual return for a financial year (e.g., GSTR-9) must be filed by 31st December of the subsequent year unless extended. If filed earlier than 30th November, that becomes the cutoff date.

If ITC is not claimed within the above timeline, it lapses and cannot be carried forward or claimed in subsequent periods.

2. Time Limit for RCM ITC

For RCM transactions, the time limits are clarified under Section 16(4) and further explained by Circular No. 211/5/2024-GST, issued on 26th June 2024. The time limits are linked to the issuance of the self-invoice and not the date of the original supply. The key timelines are as follows:

• Financial Year of the Self-Invoice: ITC is associated with the financial year in which the self-invoice is issued, irrespective of the date of the supply.
• Claim Deadline: ITC must be claimed by the earlier of:
  • 30th November of the year following the self-invoice issuance.
  • Date of filing the annual return for the financial year of the self-invoice.

This extension allows recipients to claim ITC for older RCM transactions if the self-invoice is issued in a subsequent financial year.

Illustrative Examples

Type of ITC	Transaction Date	Self-Invoice Date (For RCM)	Applicable Financial Year	ITC Claim Deadline
Normal ITC	15th February 2023	Not Applicable	2022-23	30th November 2023 or date of annual return filing (whichever is earlier)
RCM ITC	10th March 2022	15th April 2023	2023-24	30th November 2024 or date of annual return filing for FY 2023-24 (whichever is earlier)

Key Points to Note

• Normal ITC: Directly linked to the date of the supplier's invoice and dependent on the supplier's GST compliance.
• RCM ITC: Linked to the self-invoice issued by the recipient, providing additional flexibility for older transactions.
• Ensure compliance with Section 16 conditions to avoid disallowance of ITC.

Best Practices for Compliance

To ensure ITC is claimed within the prescribed timelines:

• Maintain a robust tracking mechanism for invoices and self-invoices.
• Issue self-invoices promptly for RCM transactions.
• Reconcile ITC claims with GSTR-2B to identify any missing invoices.
• File GST returns (e.g., GSTR-3B and GSTR-9) accurately and on time.

Deviation Table: ITC Timelines Before and After Amendment

Aspect	Before Amendment	After Amendment
Reference Year for ITC	Financial year of the original supply or liability.	Financial year of the self-invoice issuance.
Time Limit for Claiming ITC	Earlier of: 30th Nov of the subsequent FY or Annual Return date.	Earlier of: 30th Nov of self-invoice FY or Annual Return date.
Impact of Late Self-Invoice	Late issuance does not extend ITC eligibility.	Late issuance resets the timeline for claiming ITC.

Deviation Table: Differences Between Normal ITC and RCM ITC

Aspect	Normal ITC	RCM ITC
Definition	ITC claimed on GST paid by the supplier on outward supplies.	ITC claimed on GST paid by the recipient under the Reverse Charge Mechanism (RCM).
Who Pays GST?	Supplier collects and remits GST to the government.	Recipient directly pays GST to the government.
Requirement for Invoice	A valid tax invoice issued by the supplier.	A self-invoice issued by the recipient under Section 31(3)(f) (if the supplier is unregistered).
Timeline for Claiming ITC	Earlier of: - 30th November of the subsequent financial year. - Filing the annual return for the financial year.	Earlier of: - 30th November of the year following the issuance of the self-invoice. - Filing the annual return for the financial year of the self-invoice.
Payment Requirement	No separate payment; GST is included in the invoice paid to the supplier.	GST must be paid in cash under RCM before claiming ITC.
Claiming ITC	ITC can be claimed as soon as the invoice is available and the supplier has paid GST.	ITC can be claimed only after paying GST under RCM.
Reporting in GSTR-3B	Reported in Table 4(A) under "Eligible ITC."	Liability is reported in Table 3.1(d); ITC is reported in Table 4(A)(3).
Blocked Credits (Section 17(5))	ITC is restricted for items like motor vehicles for personal use, health insurance, etc.	Same restrictions apply to ITC under RCM.
Examples	GST paid on purchases of raw materials, office supplies, etc.	GST paid on legal services, rent, or goods notified under RCM (e.g., tobacco leaves).
Flexibility in Claim	ITC is linked to supplier's compliance and timely filing of GSTR-1 and GSTR-3B.	ITC is independent of supplier compliance but dependent on the recipient's self-invoicing and timely payment of RCM.
Payment Mode for ITC	Can be claimed immediately if all conditions are met.	GST must be paid in cash first, and then ITC can be claimed in the same or subsequent return.
