Meaning of Input Service Distributor (ISD)

Input Service Distributor is an office of the supplier of goods or services which receives input tax credits on invoices related to input services and distributes such credits to other units in the same business.

  • ISD and the units must have the same PAN.
  • ISD cannot be an office that does any supply of its own but must be one that only collects invoices for services and issues ISD invoices for its distribution.
  • ISD cannot discharge tax liability under reverse charge.
  • Credit only on input services can be distributed and not on input and capital goods.

For example,

The corporate office of ABC Private Ltd. is situated in Noida, having its branches in Noida, Bangalore, Mumbai, and Jaipur. if the legal services are used by all the branches and invoice indicating CGST and SGST is received at Corporate Office (Noida).

Since the service is used for all the units, the input credit of entire services cannot be claimed by Noida and the same should be distributed to all four units. ISD mechanism enables the proportionate distribution of credit of input services amongst all the consuming units.
