The income tax department will validate with the Institute of Chartered Accountants of India (ICAI) the unique document identification number (UDIN) of chartered accountants when they upload tax audit reports, the finance ministry said on Thursday.

To curb fake certifications by non-CAs misrepresenting themselves as chartered accountants, the ICAI in 2019 made generation of UDIN from the ICAI website mandatory for every kind of certificate and tax audit report and other attests made by their members as required by various regulators.

The ministry said that in line with the ongoing initiatives of the income tax department for integrating with other government agencies and bodies, income-tax e-filing portal has completed its integration with the ICAI portal for validation of UDIN generated from the ICAI portal by the chartered accountants for documents certified/attested by them.
