As part of updating its registry, MCA would be conducting KYC of all Directors of all companies annually through a new eform viz. DIR-3 KYC
to be notified and deployed shortly. Accordingly, every Director who has been allotted DIN on or before 31st March, 2018 and whose DIN is in ‘Approved’ status, would be mandatorily required to file form DIR-3 KYC
on or before 31st August,2018. While filing the form,the Unique Personal Mobile Number and Personal Email ID would have to be mandatorily indicated and would be duly verified by One Time Password(OTP). The form should be filed by every Director using his own DSC and should be duly certified by a practicing professional (CA/CS/CMA). Filing of DIR-3 KYC would be mandatory for Disqualified Directors also.
After expiry of the due date by which the KYC form is to be filed,the MCA21 system will mark all approved DINs (allotted on or before 31st March 2018) against which DIR-3 KYC form has not been filed as ‘Deactivated’ with reason as ‘Non-filing of DIR-3 KYC’. After the due date filing of DIR-3 KYC in respect of such deactivated DINs shall be allowed upon payment of a specified fee only, without prejudice to any other action that may be taken.
