Clarifications on Input Service Distributor (ISD) Provisions: CBIC Circular No. 260/06/2026-GST

On October 26, 2026, the Central Board of Indirect Taxes and Customs (CBIC) issued Circular No. 260/06/2026-GST, delivering essential clarifications regarding GST Input Service Distributor (ISD) provisions under Sections 2(61), 20, 21, and 122 of the CGST Act, 2017, alongside Rules 39, 54(1A), and 89 of the CGST Rules, 2017.

This circular resolves ongoing operational uncertainties for multi-locational businesses, multi-unit enterprises, and entities operating centrally managed procurement models.

Below is an in-depth summary prepared by Sagar S Gupta & Co highlighting key takeaways, compliance obligations, and financial impacts for registered taxpayers.

1. Multiple ISD Registrations Within the Same State/UT

Question: Can a business obtain more than one ISD registration within the same State or Union Territory for separate business verticals or units?

• Clarification: Under Section 25(2) and Section 25(4) of the CGST Act, separate registrations obtained for distinct business verticals or places of business within a State/UT are classified as “distinct persons”.
• Rule: The law does not bar a business from obtaining multiple ISD registrations within a single State/UT.
• Requirement: Any unit/registrant that receives input service invoices for or on behalf of distinct persons must obtain an ISD registration to distribute the credit.
• Restriction: Pursuant to Rule 39(1) of the CGST Rules, the ISD must distribute credit only to the distinct persons to whom that credit is specifically attributable.

2. Who is Responsible for Eligibility Compliance under Section 16 & Penalties?

• Liability for Conditions: The recipient of the credit (the distinct person) is strictly responsible for fulfilling the eligibility conditions prescribed under Section 16 (tax invoices, receipt of services, return filing) and Section 17 of the CGST Act[cite: 83].
• Penalty on ISD: If the ISD distributes credit in contravention of Section 20 or associated rules, the ISD is liable to a penalty under Section 122(1)(ix) (₹10,000 or the amount of credit irregularly distributed/evaded, whichever is higher)[cite: 82, 83].
• Recovery of Excess Credit: If an improper distribution by the ISD results in excess credit passed to recipient units, the excess amount will be recovered from the recipient units along with interest under Section 73, 74, or 74A[cite: 82, 83].

3. Meaning of Credit “Available for Distribution in a Month” (FORM GSTR-6)

Question: What constitutes credit “available for distribution” in a given month under Rule 39(1)(a)?

• Prima Facie Ascertainment: Input Tax Credit becomes “available for distribution” when the ISD reflects the invoices in its FORM GSTR-6A and ascertains that the credit is prima facie eligible for availment.
• Distribution Timeline: The ISD must distribute the credit in the specific month in which this ascertainment takes place.
• Separation of Credit: The ISD must distribute eligible and ineligible credit (e.g., blocked credit under Section 17(5)) separately in FORM GSTR-6 as per Rule 39(1)(g).

4. Reversal of ITC under Section 17(1), 17(2), and 17(4) (Rules 38, 42 & 43)

Question: Should common credit reversals (for exempt supplies or banking/financial rules) be executed by the ISD or the recipient unit?

• Clarification: The ISD is mandated to distribute the entire credit available to the recipient units to whom it is attributable.
• Execution: It is the recipient units that must execute common ITC reversals under Section 17(1) or 17(2) read with Rules 42 and 43, or Section 17(4) read with Rule 38. The ISD itself does not perform proportional business/non-business or taxable/exempt supply reversals.

5. Treatment of Rule 54(1A) Credit Transfer Invoices & State Turnover

Question: Does an invoice/debit note issued under Rule 54(1A) to transfer RCM/cross-charge credit to an ISD count toward the issuing unit’s “Turnover in State”?

• Background: Rule 54(1A) allows a regular registration (having the same PAN and State code as the ISD) to issue an invoice, debit note, or credit note to the ISD to transfer input service credit (such as Reverse Charge Mechanism payments) for onward distribution.
• Ruling: A Rule 54(1A) document is purely a credit-transfer mechanism and does not constitute an outward supply.
• Turnover Exclusion: The value reported on Rule 54(1A) invoices must NOT be included in calculating:
  1. “Turnover in State” or “Turnover in Union Territory” under Section 2(112) for proportional ISD distribution.
  2. “Adjusted Total Turnover” under Section 54(3) read with Rule 89 for export/zero-rated refund computations.

6. Exclusion of Rule 54(1A) Transferred Credit from “NET ITC” in Refund Claims

Question: Can a regular unit include credit transferred to an ISD under Rule 54(1A) as part of its “Net ITC” for claiming refunds under Rule 89(4) or Rule 89(5)?

• Ruling: No. Credit transferred under Rule 54(1A) does not represent inward supplies consumed by the transferring unit itself.
• Impact: It cannot be included in “Net ITC” when calculating GST refunds under Rule 89(4) (inverted duty structure / zero-rated without payment of tax) or Rule 89(5).

7. No Requirement of ITC Reversals on Rule 54(1A) Transfers by Transferring Unit

Question: Is the registered person who transfers RCM credit to the ISD under Rule 54(1A) required to make Section 17 reversals before transferring?

• Clarification: The transferring entity is not required to perform any Section 17(1), 17(2), or 17(4) reversals on RCM credit passed under Rule 54(1A).
• Mechanism: The transferring unit passes the 100% credit to the ISD. The ultimate recipient units (which may include the original transferring unit in its capacity as an end-recipient) will perform the required Rule 42/43 reversals upon receiving their distributed share from the ISD.
