The ISD mechanism ensures that ITC from shared services, such as audit fees, legal consultation, and software subscriptions, is correctly allocated to branches that actually utilize these services.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Previously, ISD registration was optional, but with the new mandate under GST, businesses meeting the criteria must comply to avoid potential disallowances or penalties.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">This change is enforced under Notification No. 16\/2024-Central Tax, dated August 6, 2024, which makes ISD provisions mandatory from April 1, 2025.
