Dematerialisation is the process of converting physical securities, like share certificates, into an electronic format, which is then held in a Demat account. These securities are managed by a depository through a registered Depository Participant (DP). In India, the main depositories are NSDL (National Securities Depository Ltd.) and CDSL (Central Depository Services Ltd.).
In October 2023, the Ministry of Corporate Affairs (MCA) amended the Companies (Prospectus and Allotment of Securities) Rules, 2014 by adding Rule 9B, which mandates private limited companies (except small ones) to dematerialise their shares by September 30, 2024.
Small companies (with a paid-up capital under ₹4 crore and turnover below ₹40 crore) are exempt from the dematerialisation requirement, unless they are a holding or subsidiary company, in which case they must comply.
