Starting November 1, 2024, a new regulation under the GST regime is set to change how businesses handle Reverse Charge Mechanism (RCM) self-invoicing, especially for transactions with unregistered suppliers.
Until now, the rules around issuing self-invoices under RCM were vague, often leading to delays, missed Input Tax Credit (ITC) claims, and compliance hassles. But with the introduction of Rule47A and a clearer definition of time of supply, the government is aiming to tighten the compliance framework and close any existing loopholes.
So, what exactly is changing? Who needs to worry about these new timelines? How will it affect your business if you’re dealing with unregistered vendors?
In this blog, we break down everything you need to know about the new RCM self-invoicing regulation effective from November 1, 2024—from the technical details to real-world impact and compliance tips.
RCM or Reverse Charge Mechanism is a provision under GST where the liability to pay tax shifts from the supplier to the recipient of goods or services. This provision primarily applies in the following two cases:
The idea behind RCM is to plug revenue leakages in cases where suppliers are not registered under GST or are operating in sectors with a high level of tax evasion.
When a registered recipient procures goods or services from an unregistered supplier, they are required to issue a self-invoice since the supplier cannot issue a GST-compliant invoice. This process is known as RCM self-invoicing.
Under GST law, self-invoicing serves as proof of the transaction and becomes a crucial document for tax payment and input tax credit (ITC) eligibility.
With effect from November 1, 2024, the government has inserted Rule 47A in the CGST Rules, 2017. This rule mandates that the recipient liable to pay tax under RCM must issue the self-invoice within 30 days from the date of receipt of goods or services from the unregistered supplier.
Self-Invoice No: RCM/001/2024
Date of Issue: November 15, 2024
Recipient: XYZ Pvt. Ltd. (GSTIN: 29xxxxxxx)
Supplier: Mr. A (Unregistered)
Description: Consulting services
Date of Receipt: November 5, 2024
Amount: Rs. 20,000
Tax: IGST @18% = Rs. 3,600
Total: Rs. 23,600
The introduction of Rule 47A is part of a broader effort to:
Until now, there was no fixed timeline for issuing self-invoices under RCM, which led to widespread confusion and potential ITC claim rejections.
As per the amended provisions of the CGST Rules and Section 31:
Under Section 16(4) of the CGST Act, the recipient can only avail of ITC within a specified time frame:
But for RCM transactions involving self-invoices, the relevant year is calculated from the date of the self-invoice.
Some industries rely heavily on purchases from unregistered suppliers. These include:
These sectors must now revisit their procurement processes to ensure compliance.
Goods received: November 5, 2024
Payment made: November 20, 2024
Self-invoice must be issued by December 5, 2024
Time of supply: November 5, 2024 (earliest of three events)
Services received: November 10, 2024
Payment made: November 25, 2024
Self-invoice issued: November 15, 2024
Time of supply: November 15, 2024 (earlier of payment and invoice)
These changes demand that businesses adopt proactive documentation strategies.
The introduction of Rule 47A marks a pivotal change in the way businesses handle purchases from unregistered suppliers under the Reverse Charge Mechanism. With a clear 30-day deadline now in place, businesses must update their invoicing practices, monitor procurement closely, and issue self-invoices promptly to remain compliant.
Failing to issue timely self-invoices could lead to loss of input tax credit, late payment interest, and penalties. Affected sectors, especially insurance, logistics, and real estate, should act fast and implement systems for seamless GST under RCM compliance.
The new regulation on RCM self-invoicing, effective from November 1, 2024, isn’t just a procedural update – it’s a shift in accountability that calls for timely action and organised compliance from every GST-registered business.
No, Rule 47A specifically applies to transactions under the Reverse Charge Mechanism (RCM) involving unregistered suppliers. If the supplier is registered under the GST, this rule is not applicable. The objective is to ensure tax compliance when the supplier isn’t obligated to generate an invoice under GST.
If the self invoice is not issued within 30 days of receiving the goods or services from an unregistered supplier, Input Tax Credit (ITC) can be disallowed.Additionally penalties under Section 122of the CGST Act may apply for non-compliance, including fine or interest.
No, you don't need to issue a self-invoice in this case. A registered supplier is required to issue a tax invoice under GST . Rule 47A is not applicable when the purchase is made from a GST-registered dealer, regardless of whether RCM applies.
No, self-invoices must be issued only after the receipt of goods or services, not before. According to Rule 47A, businesses are required to generate self-invoices within 30 days of receipt, ensuring accurate timing and compliance with GST invoicing provisions under RCM.
Yes, insurance companies may be significantly impacted by this rule, especially when they deal with unregistered agents, consultants, or service providers. In such cases, they must issue self-invoices within 30 days under Rule 47A and pay GST under RCM to claim ITC.
