Dematerialisation
of Shares —
Complete Guide 2025
Converting physical share certificates into electronic form is now mandatory for all unlisted public companies (Rule 9A) and private companies except small companies (Rule 9B) under the Companies Act 2013. TAXAJ's CS + CA team handles the complete dematerialisation — ISIN allocation, RTA coordination, NSDL/CDSL registration, and shareholder communication.
Dematerialisation of Shares in India — Complete Legal Guide 2025
Dematerialisation of shares (also spelled dematerialization) is the process of converting physical share certificates — paper documents representing ownership of company shares — into electronic records held in a DEMAT (Dematerialised) account. Instead of paper certificates, shares are stored digitally by India's two government-registered depositories: the National Securities Depository Limited (NSDL) and the Central Depository Services (India) Limited (CDSL).
In India, dematerialisation was introduced in 1996 through the Depositories Act and was initially mandatory only for listed companies. The Ministry of Corporate Affairs has progressively extended this requirement to unlisted public companies (Rule 9A, effective October 2018) and private companies except small companies (Rule 9B, effective October 2023). As of 2025, over 100,000 companies have already dematerialised their shares, with NSDL reporting its issuer base growing from 40,000 in FY23 to over 100,000 by late 2025.
Key Terms in Dematerialisation
Understanding dematerialisation requires familiarity with a few key stakeholders and concepts:
- Depository — NSDL or CDSL; holds electronic securities and maintains records
- Depository Participant (DP) — Intermediary between the investor and depository (Zerodha, Groww, Sharekhan, banks etc.)
- RTA (Registrar and Transfer Agent) — Intermediary between the company and depository; processes DEMAT requests and maintains shareholder records
- ISIN (International Securities Identification Number) — A unique 12-character alphanumeric code assigned to each class of company securities; required before any dematerialisation can begin
- DRF (Dematerialisation Request Form) — Form filled by shareholders to initiate dematerialisation of their physical certificates
- DEMAT Account — Electronic account in which dematerialised shares are held, opened with a Depository Participant
What Securities Must Be Dematerialised?
Rule 9A and Rule 9B specify "securities" as defined under Section 2(81) of the Companies Act read with Section 2(h) of the Securities Contracts (Regulation) Act, 1956. This means all forms of securities must be dematerialised, not just equity shares:
- Equity shares (ordinary and founders' shares)
- Preference shares (compulsorily and optionally convertible)
- Compulsorily Convertible Preference Shares (CCPS)
- Debentures and Non-Convertible Debentures (NCDs)
- Bonds issued by the company
Each class of security gets a separate ISIN. A company with equity shares and CCPS needs at minimum two ISINs — one for each class.

Benefits of Dematerialisation of Shares for Indian Companies
Beyond mandatory compliance, dematerialisation offers significant practical and commercial advantages for the company, its shareholders, and potential investors.
Eliminate Risk of Loss, Theft & Damage
Physical share certificates can be lost, damaged in a flood or fire, or stolen. Electronic shares in a depository are permanently backed up and cannot be physically destroyed. Ownership disputes become almost impossible with electronic audit trails.
Faster Share Transfers
Physical transfers require board approval, stamp duty on instruments, physical delivery of certificates, and weeks of processing. DEMAT transfers happen in T+2 business days (or instantaneously for off-market transfers) with minimal paperwork.
Easier Fundraising & FDI
Angel investors, VCs, and foreign investors strongly prefer or require DEMAT shareholding before investing. FDI into Indian companies and startup fundraising is dramatically smoother when shares are already in DEMAT form. Due diligence is faster and cleaner.
Pledge Shares for Loans
DEMAT shares can be pledged with banks and NBFCs as collateral for loans much more easily than physical certificates. Banks can verify pledged shares electronically with the depository — no physical surrender required.
Accurate Cap Table & Shareholder Records
Depository records provide a real-time, authoritative view of shareholder composition. Combined with the Register of Members (MGT-1), companies have two independent data sets to cross-verify, eliminating ghost shareholders and ownership disputes.
Smoother Path to Stock Exchange Listing
Companies planning to list on BSE SME or NSE Emerge need their shares in DEMAT form before the IPO filing. Dematerialising early removes a major bottleneck in the pre-IPO valuation and listing process. SEBI requires 100% DEMAT shareholding before any public offer.
How to Dematerialise Shares of a Company — Step-by-Step Process
The dematerialisation process involves both the company (obtaining ISIN, appointing RTA) and the shareholders (opening DEMAT accounts, submitting DRF). TAXAJ coordinates both sides.
Board Resolution — Company Decision to Dematerialise
The company's Board of Directors passes a resolution authorising the dematerialisation of its securities. This resolution should authorise a director or the CS to apply for ISIN, appoint an RTA, enter into a tripartite agreement with the depository and RTA, and communicate with shareholders. The Board resolution must be recorded in the minutes book and filed in MGT-14 if required.
Appoint Registrar & Transfer Agent (RTA)
The company must appoint a SEBI-registered RTA (Registrar and Transfer Agent) to act as the intermediary between the company and the depository (NSDL/CDSL). The RTA maintains the shareholder register in digital form, processes DRF (Dematerialisation Request Forms) from shareholders, coordinates ISIN requests, and issues electronic share certificates. Sign an agreement with the RTA. Popular RTAs include MUFG Intime (formerly Link Intime), KFin Technologies, and Alankit Assignments.
Apply for ISIN — International Securities Identification Number
Apply to NSDL or CDSL (through the RTA) for an ISIN for each class of securities. The ISIN is a 12-character alphanumeric code (e.g., INE123A01010) that uniquely identifies the company's securities in the depository system. A separate ISIN is required for each class — equity shares, preference shares, debentures etc. The ISIN application requires: Board resolution, Certificate of Incorporation, PAN of the company, latest shareholding pattern, and the company's IEPF account details.
Tripartite Agreement — Company, RTA, and Depository
The company, its RTA, and the depository (NSDL or CDSL) must sign a Tripartite Agreement that governs the relationship between the three parties — defining responsibilities for ISIN maintenance, processing of DEMAT requests, corporate actions (bonus, dividend, split), and data reconciliation. This agreement is a prerequisite for the depository to activate the ISIN and begin processing DEMAT requests from shareholders.
Communicate with Shareholders — ISIN + DEMAT Account Instruction
Once the ISIN is allocated and the tripartite agreement is signed, the company must inform all shareholders by letter or email about: (a) the ISIN allocated to their shares, (b) the requirement to open a DEMAT account with any Depository Participant (DP) if they don't already have one, (c) the process to submit the Dematerialisation Request Form (DRF) along with original share certificates to their DP. The notice must be sent to every registered shareholder using their registered address from the Register of Members.
Shareholders Submit DRF — Physical Certificates to DP
Each shareholder who holds physical certificates must: (1) open a DEMAT account with a Depository Participant (DP) like Zerodha, Groww, bank etc., (2) fill in a Dematerialisation Request Form (DRF) specifying the company ISIN, number of shares, and certificate numbers, (3) submit the DRF along with the original physical share certificates to the DP. The DP forwards the DRF to the RTA for verification and cancellation of physical certificates.
RTA Verifies, Cancels Physical Certificates & Confirms to Depository
The RTA verifies the DRF and original certificates against the company's register of members. On successful verification, the RTA physically cancels/mutilates the original share certificates (stamps "CANCELLED" on them) to prevent any reuse. The RTA then confirms the dematerialisation request to the depository, which credits the equivalent number of electronic shares to the shareholder's DEMAT account. The process typically takes 7–15 working days from DRF submission.
Update Records & File PAS-6
Once dematerialisation is complete, update the Register of Members (MGT-1) to reflect that shares are now held in DEMAT form. Update the share transfer register (SH-6) accordingly. For unlisted public companies, file the half-yearly Form PAS-6 (Reconciliation of Share Capital Audit Report) with the ROC to confirm that DEMAT + physical shares reconcile to the total issued share capital. PAS-6 is due by 29 November (for Apr–Sep period) and 29 May (for Oct–Mar period).
Documents for Dematerialisation — Company & Shareholders
Non-Compliance Penalties — Rule 9A & Rule 9B
No specific penalty section was initially defined for dematerialisation violations — Section 450 (general penalty) applies. As awareness grows, ROC is increasingly issuing compliance notices.

| Promoter not DEMAT before new issue | 9A(4) | Issue invalid | Fine + criminal liability | Per issue |
| PAS-6 Non-Filing (Public Companies) | ||||
| Not filing Form PAS-6 on time | Sec 450 | ₹10,000 | ₹10,000 | ₹1,000/day |
