e-filing portal will the tax reports/forms be considered as legitimate.

UDIN is evaluated by an online e-filing portal with the three variables of the ICAI UDIN portal:

In view of the same, such members are requested to update the UDINs on the e-filing Portal at the earliest but not later than 31st of December 2020 for all such IT Forms which have been uploaded by them from 27th of April 2020 onwards till 26th of November 2020. For facilitation of Members, the steps and screenshots of the e-filing portal involved for updating UDIN are available. Members may kindly note that UDIN is treated as consumed when it is accepted by the Taxpayer. Once the UDIN is updated by the member, the e-filing portal automatically validates it and shows an error message if it is not validated successfully.
