Dematerialization Account Rules for Private Companies (2025)

Key Takeaways:

• The final deadline for mandatory dematerialization of eligible private company shares was June 30, 2025, extended twice from the original March 2023 date.
• This is governed by MCA's Rule 9B, with SEBI's role limited to regulating the depositories (NSDL/CDSL) that hold the dematerialized shares.
• Small companies and producer companies (extended to 2028) are exempt from this specific timeline.
• Missing the deadline blocks physical-form transfers, bonus issues, and rights issues and can trigger penalties under Section 450.
• Shareholders need an active dematerialization account, trackable through a demat account app, once the company completes its own ISIN and RTA setup.

How Dematerialisation of Private Company Shares Works After the 2025 SEBI Deadline

Now, as someone who has investments in a private company, you must be aware of the fact that having only paper share certificates won't suffice anymore. This is because the deadline of June 30, 2025, for mandatory dematerialization has passed, and now companies that have failed to meet this requirement are being restricted from transfers, buybacks, and issuance of new shares. 

What Is a Dematerialisation Account?

A dematerialization account, commonly called a demat account, is an electronic record that holds your securities instead of paper certificates. Once shares are dematerialized, they exist only as digital entries linked to your dematerialization account, held with a depository such as NSDL or CDSL. There's nothing to lose, forge, or misplace physically; everything sits in one digital record you can check anytime through a demat account app.

In private companies, this change came about as a result of the introduction of Rule 9B in the Companies (Prospectus and Allotment of Securities) Rules, 2014, made by the Ministry of Corporate Affairs in October 2023. What needs to be pointed out here is that this is an MCA rule rather than a SEBI regulation directly. Since the depositories holding these dematerialised shares (NSDL and CDSL) are regulated by SEBI under the Depositories Act, 1996, the transfer must be completed within the timelines prescribed by SEBI. 

The Timeline: How the Deadline Moved

The initial date was set on March 31, 2023, which was changed to September 30, 2024, and further to June 30, 2025, due to another notification dated February 12, 2025, which was specifically for private companies, section 8 companies, and nidhi companies. In contrast, producer companies were given till March 31, 2028, while small companies, as per the Companies Act, are exempted from this provision.

Since we're now past that final date, any non-small private company that hasn't dematerialized its shares is technically out of compliance. That has practical consequences, not just paperwork ones.

What Happens If a Company Misses the Deadline

Companies without a completed dematerialization account setup face a few concrete restrictions:

• No new share issuances, transfers, bonus issues, or rights issues can happen in physical form.
• Shareholders can't transfer their holdings until the shares are converted.
• Non-filing of Form PAS-6 within the required timeline can attract penalties under Section 450 of the Companies Act, fines that apply both to the company and to defaulting officers, plus a daily charge for continuing non-compliance.

This is not just an assumption but rather an expected result, which will depend on the particular situation and evaluation carried out by the Registrar of Companies. But the trend is obvious: possession of the shares will limit the options for their usage after this moment.

How the Process Actually Works

Step 1: The company appoints a Registrar and Transfer Agent (RTA).

The RTA acts as the go-between for the company and the depositories.

Step 2: The company gets an ISIN.

Every class of security needs its own International Securities Identification Number before it can move into electronic form.

Step 3: Shareholders open a dematerialization account.

If you don't already have one, this is the point where you'll need to set one up with a depository participant.

Step 4: Physical certificates get surrendered and converted.

Once your request is processed by the Registrar and Transfer Agent (RTA), your shares are credited to your demat account as electronic holdings, viewable instantly through a demat account app.

Common Doubts Shareholders Have

Do I need a new dematerialization account for private company shares, or can I use my existing one? 

If you already hold listed securities in a demat account, the same account generally works for private company shares too, once the company completes its own compliance.

Is my ownership at risk during the conversion? 

No dematerialization converts the form of your holding, not the ownership itself. Your rights as a shareholder stay intact throughout.

What if the company itself hasn't started the process? 

As a shareholder, you can only dematerialize once the company has appointed an RTA and obtained an ISIN. Reach out to the company secretary for a status update.
