ICAI Clarifies 60-Tax Audit Ceiling for UDIN Generation from April 2026

The FAQs on ceiling for UDIN generation under Tax Audit clarify the implementation of the 60 Tax Audit assignment limit per financial year per Chartered Accountant, effective from 1 April 2026 under the “Chartered Accountants (Limit on Number of Tax Audits) Guidelines, 2025.” The ceiling applies only to specified sub-categories under “GST & Tax Audit,” namely Form 3CA and certain Form 3CB categories under Sections 44AB(a), 44AB(b), and combined Form 3CB audits. The limit is computed based on the date of signing of the Tax Audit Report and not the date of UDIN generation. The UDIN system will aggregate audits undertaken in individual capacity and across firms. Revised Tax Audit Reports will not be counted as separate assignments. Head office and branch audits of the same assessee for the same assessment year will be treated as one assignment, while different assessment years will count separately. Multiple forms for the same assessee and assessment year will also be treated as a single assignment.

Q3. How is the 60-audit limit calculated?
