ICAI Introduces Major UDIN Updates: Audit Ceiling, Mobile App and Enhanced Validations The Institute of Chartered Accountants of India (ICAI) has recently made several new updates to the Unique Document Identification Number (UDIN) system. The main objective of introducing these changes is to make things more transparent and ensure better compliance. The following are the main changes: Audit Ceiling Implementation Starting April 1, 2026, there will be a strict limit on the number of tax audits each member can do. Every member will be allowed to complete only up to 60 tax audits, and this rule will be monitored through the UDIN portal to ensure no one exceeds the limit.
