ISD Mechanism is mandatory w.e.f. 01-April-2025!

The Input Service Distributor (ISD) is a vital concept under the GST regime that ensures the proper distribution of input tax credit (ITC) across multiple business locations. An ISD is an office of a supplier that receives tax invoices for input services and distributes the eligible ITC to its branches or units registered under the same Permanent Account Number (PAN). This mechanism helps in allocating tax credits for services used across different locations, ensuring financial accuracy and compliance.

With effect from April 1, 2025, Input Service Distributor (ISD) provisions have been made mandatory where any office of the supplier of goods or services (or both) receives tax invoices for input services, including invoices for services liable to tax under reverse charge. This amendment ensures that ITC for reverse charge transactions under the IGST Act is distributed appropriately across different registered locations of the same business.

Let’s understand in detail!

Understanding the ISD Mechanism

An ISD is an office of a supplier that receives tax invoices for input services and distributes the eligible ITC to its branches or units registered under the same Permanent Account Number (PAN). Following is the process of the ISD mechanism:

• Receipt of the goods or service at the branch
• Receipt of the purchase invoice in the same as the ISD
• ISD shall reconcile the ITC in its GSTR 6A- Statement of Inward Supplies for an ISD.
• Calculation of ITC for services used by a specific branch
• Calculation of distribution of common ITC per turnover by ISD
• Filing Form GSTR 6 to distribute the ITC to the branch
• Branch files GSTR 3B to claim such ITC.

What happens if ISD provisions are not followed?

Non-compliance may result in:

• Denial of ITC to recipient units
• Interest & penalties under GST law
• Increased litigation risk during audits

Key Changes Effective from April 1, 2025

Starting April 1, 2025, significant amendments to the ISD mechanism under the GST regime will take effect and they’re set to impact businesses across industries. Here’s what’s changing:

1. Mandatory ISD Registration: It’s now compulsory for any business receiving common input service invoices for multiple branches to register as an Input Service Distributor (ISD). This move aims to streamline ITC distribution and enhance tax compliance, especially for businesses with centralized service procurement.

2. Reverse Charge ITC (RCM) Now Distributable: Input Tax Cred it (ITC) on reverse charge mechanism (RCM) can now be distributed through the ISD. Previously, ISD could not claim RCM ITC, which created compliance gaps and complex tax structures for businesses. This change simplifies ITC management for inter-branch services and expenses liable to reverse charge tax.‍

3. Strict Compliance and Penalties: Businesses failing to comply with ISD provisions including non-registration, incorrect ITC distribution, or non-distribution of eligible ITC will face GST notices and penalties. With the ISD mechanism becoming mandatory, proper record-keeping and accurate credit distribution will be crucial to avoid legal and financial consequences.

Conclusion

The mandatory ISD mechanism from April 1, 2025, is a crucial step toward better ITC management and GST compliance. By ensuring proper distribution of tax credits including those under reverse charge businesses with multiple locations can maintain financial accuracy and avoid legal issues.

With strict penalties for non-compliance, timely ISD registration and accurate ITC distribution are essential. Businesses should act now to align their processes with these new requirements and avoid any future complications.
