The central board of direct taxes (CBDT) has prolonged the last date to update the Unique Document Identification Number (UDIN) for practising the CAs till 30th June 2022, to provide much more time to CAs to validate effectively and upload UDINs.
Unique Document Identification Number (UDIN) being made compulsory from 1st July 2019 for all Audit/Assurance/Attest functions.
The idea of UDIN (Unique Document Identification Number) is executed to restrict the bogus activities of concealing the facts towards authorities and stakeholders by the non-CMAs showing themselves as CMAs and attesting the Costing Data/documents/certificates.
UDIN ensures the certificates are attested/certified through practising CMAs (in full-time practice only). UDIN Web Portal enables third parties (Authorities / Regulators / Banks / Others) to inspect the genuineness of the document. Unique Document Identification Number (UDIN) is an 18-digit system-generated Unique Number for every document Certified / Attested by Practicing CMAs. UDIN is to be generated during the time of signing of the document [for each assignment] via UDIN Portal, but that would be generated within 60 days of signing the document.
