Distribution of Input Tax Credit (ITC)

Process of Distributing ITC

The ISD process follows a structured workflow to distribute Input Tax Credit (ITC) to business units or branches within an organization.

Step 1: Procurement of Input Services
The ISD centrally procures input services, such as accounting, legal, or IT services, on behalf of multiple business units or branches. The invoices for these services are addressed to the ISD.

Step 2: Apportioning ITC
The ISD calculates the total ITC available based on the invoices it has received. It then apportions the available ITC to the respective business units or branches that will utilize these services.
The apportionment is typically based on the ratio of each business unit or branch’s turnover to the total turnover of the organization.

Step 3: Filing GST Form GSTR-6
The ISD is required to file monthly returns using GST Form GSTR-6. This return provides details of the ITC received and distributed during the month.

Step 4: Claim by Units
The business units or branches receiving the ITC can claim it in their respective returns.

Step 5: Utilization
The recipients of ITC can use the credit to offset their GST liability on outward supplies, reducing their overall tax liability.

Using GST Form GSTR-6

The Input Service Distributor uses Form GSTR-6 for the following purposes:

  • Disclose all ITC received by the ISD on behalf of its business units.
  • Distribute the ITC to the business units based on their usage.
  • File a monthly return with the GST authorities to report the ITC received and distributed during the month.

Form GSTR-6 is a critical document for ISDs, as it ensures that the ITC is distributed accurately and efficiently. It also helps businesses to comply with the GST law.

Challenges and Compliance for ISD

Ensuring Accurate ITC Distribution

One of the key challenges for an Input Service Distributor under GST is ensuring that Input Tax Credit (ITC) is accurately distributed to the various business units. Any discrepancies or errors in distribution can lead to compliance issues and the loss of legitimate tax credits.

Complying with GST Regulations

Input Service Distributors (ISDs) must be meticulous in complying with GST regulations. This includes:

  • Timely filing of Form GSTR-6: ISDs must file Form GSTR-6 on time to report the distribution of ITC. Late filing of Form GSTR-6 can result in penalties.
  • Accurate reporting of ITC: ISDs must accurately report all ITC received and distributed on Form GSTR-6. Inaccurate reporting of ITC can lead to compliance issues and penalties.
  • Adherence to GST guidelines: ISDs must adhere to all GST guidelines, including those related to ITC distribution. Non-compliance with GST guidelines can result in penalties and legal repercussions.


ISDs are intermediaries that help businesses distribute ITC to their various branches or units. This can be a complex and time-consuming process, especially for large organizations with multiple locations. ISDs automate this process, making it more efficient and accurate.

ISDs also help businesses to comply with GST regulations. By ensuring that ITC is distributed correctly, ISDs can help businesses avoid penalties and fines from the GST authorities.
