Input Service Distributor (ISD) under GST

Input Service Distributors are individuals responsible for distributing GST ITC or input tax credits. The ISD should maintain tax credits to any company’s branches with a distinct GSTIN or their GSTIN registered within the same PAN. In this post, you can learn about the meaning and benefits of an ISD in GST in detail.

Who is an Input service distributor (ISD) under GST?

ISD full form in GST is input service distributor. The input service distributor means a taxpayer who receives the invoices for services its branches utilize. They are responsible for distributing the tax paid, referred to as the Input Tax Credit. These taxes are distributed to the branches proportionally, and they issue ISD invoices accordingly. Furthermore, having the same PAN number as the ISD is mandatory, even if the branches have different GSTINs.

Here is a simple example to help you comprehend how Input Service Distributors work. Suppose a company named M/s XYZ Limited is situated in Bangalore and has branches in Kolkata, Mumbai, and Chennai. The main office paid the annual software maintenance cost, covering all branches’ services, and has received the corresponding invoice. 

However, since all the branches utilize the software, it cannot claim the entire input tax credit in Bangalore. Instead, it must allocate the credit to all three locations. In this scenario, the head office in Bangalore serves as the Input Service Distributor.

Role of ISD under ITC

Now that you know what is ISD in GST, learn about the role played by them here:

1. Service Invoices and Distribution 

Providers who charge GST send bills to ISD for shared services. ISD distributes the tax paid to such providers by sending invoices to units that share a PAN but receive services from different providers.

2. Credit Distribution 

ISD cannot claim an input tax credit for its paid tax since it does not directly use services. Instead, it has to credit actual service recipients that are part of the same PAN.

Circumstances When an Entity Cannot Function as an ISD Under GST

As per ISD meaning, Input Service Distributor (ISD) is unable to allocate the available Input Tax Credit (ITC) from its electronic credit ledger in the following scenarios:

  1. This restriction only applies to firms who have completed the company registration and GST registration processes when transferring ITC to third-party or outsourced manufacturers or service providers. It is not permissible for the ISD to transfer ITC to unrelated or non-member organisations.
  2. When input goods or capital goods—such as raw materials, machinery, and other related costs—are claimed for Input-Tax Credits. This need is significant for businesses that have finished the required ISD in GST and company registration. It is against the law for the ISD to distribute ITC for input products or capital costs.

These limitations are designed to ensure that an ISD’s distribution of ITC complies with the GST framework’s established boundaries. Proper company registration and GST registration are crucial for companies seeking to harness the advantages of GST and streamline their tax-related procedures.

Benefits of Registering as an Input Service Distributor (ISD) under GST for Company Registration

According to ISD meaning, when registering a firm, there are several benefits to becoming an Input Service Distributor (ISD) under the Goods and Services Tax (GST) system. Businesses may improve their operations, maximise tax credits, and streamline financial procedures by realising the advantages of ISD registration. The following are the main benefits of registering your firm as an ISD under GST:

1. Centralized Management of Input Tax Credit (ITC) for Company Registration and GST Registration

For your business registration, ISD registration offers a centralised method of administering Input Tax Credit (ITC). Businesses can divide ITC among several branches or units during GST registration in an effective manner by registering the head office or centralised head office as an ISD. This expedited method guarantees GST compliance for your company registration and streamlines the distribution of ITC.

2. Seamless Allocation of Common Expenditure for Company Registration

For businesses that share substantial registration costs, ISD registration is quite advantageous. It facilitates using a centralised billing or payment system, simplifying the distribution of shared costs across several branches or units. This facilitates your business and ISD GST registration, streamlines the accounting procedure, and enhances cost control.

3. Improved Cash Flow for Company Registration and GST Registration

By taking advantage of the Input Tax Credit (ITC) during company registration and GST registration, ISD registration enables businesses to maximise cash flow. Businesses can lower individual tax obligations, manage cash flow more efficiently, and boost working capital by allocating ITC to qualified branches or units.

The Conditions to be fulfilled by an Input Service Distributor 

The crucial conditions that an ISD must fulfil compulsorily are:

1. Registration

An input service distributor must register under GST as an ISD. After an input service distributor registers in the ISD GST register as a regular taxpayer, this registration is an extra step in the procedure. This type of taxpayer must register as an ISD under GST under serial number 14 of the REG-01 form. The Input Service Distributor can only provide the recipients access to the credits following the registration procedure. 

2. Invoicing

The only way to distribute credits is to issue an ISD invoice for the tax credits. 

3. Returns

Under GST, the ISD must ensure that after each month, the credit amount does not exceed the tax credit available through the input service distributor. The credit amount that has been distributed has to be recorded in GSTR-6 by the thirteenth day of the next month. 

The tax credit that ISD has disbursed is visible to the beneficiary of the credit in GSTR-6A, which is automatically filled in using the supplier’s return. The receiving branch can then claim it by making a statement in GSTR-3B. An ISD is not obliged to submit Form GSTR-9 every year.

Distribution of ITC

Recipients are not entitled to the tax credit due to the reverse charge mechanism. The input service distributor, in this instance, must claim this credit in the same manner as a regular taxpayer.
