ICAI said the revisions were made to improve the classification of documents generated through the UDIN Portal and to make the categorisation system more comprehensive and user-friendly for members. As part of the changes, the existing "Certificates" category has been renamed "Certificates and Other Reports." Apart from the above, the "GST & Tax Audit" category has been renamed "Tax Audit." However, ICAI has clarified that the "Audit & Assurance Functions" category will remain unchanged, and no modifications have been made to its classification or scope. The Institute has advised all members to take note of these revisions and use updated categories while generating UDIN on the portal. The changes are effective for all future document registrations through the UDIN system.
