Input Service Distributor (ISD) under GST
An ISD refers to the one who supplies goods or services or both, which receives tax invoices towards receipts of input services and issues a document for the distribution purpose of taxes paid on the services. ISD mechanism is for distributing credit on common invoices related to input services only, not goods or inputs or capital goods. ISD enables the accurate distribution of credit of input services among all the consuming units. This article contains all details regarding the input service distributor (ISD) under GST.
To get registered separately under the GST, an ISD has to file GSTR REG-1 and there is no threshold limit to get registered as an ISD. The main office and its other units can be registered separately as ISD. To distribute Input Tax Credit, an ISD has to issue invoices clearly stating that such invoice is issued for distribution of ITC only.
For Example, a company has its head office in one place and units at others which may be registered separately under GST. The head office is procuring some services that may be for common utilization of all units across the country. The head office only will raise bills for the services though it does not provide any output supply. Such common expenditure is meant for the business of all units and the credit of input services is to be apportioned among all the consuming units.

Circumstances When ITC is Not Available?
Under the following circumstances, an ISD cannot claim any Income Tax Credit.
- An ISD is not able to distribute ITC to outsourced manufacturers or service providers
- When the ITC is paid on inputs or capital goods, for example, raw material or purchase of machineryÂ
The ISD mechanism is beneficial for the business having a large share of common expenditure and billing. It simplifies the ITC claiming process as the payment is made from a centralized location. ISD ensures a smooth flow of credit under the GST regime.
