In simple words: This article explains the return from a practical filing perspective—what information belongs in it, which records should support it, how to reconcile it and what can go wrong if the data is reported incorrectly.
1. 1. What is an ISD?
An Input Service Distributor receives specified input-service invoices and distributes the eligible/ineligible credit to its distinct recipient registrations according to the applicable GST rules.
