Clarifications on Input Service Distributor (ISD) Mechanism

[GST Circular No. 260/06/2026-GST dated October 26, 2026]

The Central Board of Indirect Taxes & Customs (CBIC) has issued Circular No. 260/06/2026-GST dated October 26, 2026. This circular provides critical procedural clarifications under Section 20 of the CGST Act regarding the operation, distribution timelines, tax compliance responsibilities, and refund calculations for Input Service Distributors (ISD).

Key Highlights & Clarifications

·         Multiple ISD Registrations Permitted: There is no legal restriction under the GST framework preventing a company from obtaining more than one ISD registration for separate business verticals or distinct places of business within a single State or Union Territory.

·         Compliance Liabilities Shared:

o    The ISD office is responsible for distributing the credit proportionally to the specific distinct locations to which the input service is actually attributable. If the ISD distributes excess credit irregularly, it faces statutory penalties.

o    The end-recipient units are responsible for fulfilling eligibility conditions under Sections 16 and 17, including executing any required credit reversals.

·         Defining the Distribution Month: Under Rule 39(1)(a), credit must be distributed in the same month it becomes "available". The CBIC clarifies that credit is considered available only when the ISD office ascertains that it is prima facie eligible for availment, and it must be distributed in the month this internal verification takes place.

·         Rule 54(1A) Invoices Excluded from Turnover: Regular registrations transferring credit (like tax paid under the Reverse Charge Mechanism) to an ISD office via Rule 54(1A) are using a purely operational credit-transfer mechanism. Consequently:

o    These transfer amounts do not qualify as "turnover in a State/UT" for the transferring unit.

o    These funds cannot be counted as "Net ITC" to claim maximum export refund calculations under Rule 89.

o    The transferring unit is exempt from making ITC reversals under Section 17 on these amounts; the reversal liability remains solely with the ultimate recipient units.
