From ROC Filings to ISIN Allotment: The Complete Demat Process for Indian Startups

Most guides on startup dematerialisation describe the concept clearly but leave founders without a concrete action sequence. They know what demat is, they understand why investors require it, and they have read about the documents involved. What they are missing is the precise order of operations which filing triggers which next step, who is waiting on whom at each stage, and what the dependencies are between the ROC layer, the depository layer, and the individual shareholder layer.

This guide gives you that sequence in full. Every step is described with what happens, who does it, what document it produces, what the next step depends on it for, and what goes wrong when it is done incorrectly. Follow this in order and you will have a complete demat record with no gaps, reconciled against your ROC filings, ready for investor verification.

KEY TAKEAWAYS

• The demat process has three parallel tracks that must be coordinated: the ROC compliance track, the depository track, and the shareholder coordination track.
• ROC filings (specifically PAS-3 returns) are not just a compliance obligation they are the documentary foundation that the depository uses to verify your share allotment history.
• The tripartite agreement between company, DP, and RTA is a prerequisite for the ISIN application get it signed before anything else in the depository track.
• Allotments made after the MCA mandate came into effect must be in demat form any allotment processed as physical post-mandate needs retroactive remediation before closing.
• The final deliverable is not just an ISIN it is a reconciled depository record where every shareholder's holding matches every ROC filing exactly.

The Three Parallel Tracks of the Demat Process

The demat process is not a single linear sequence. It runs across three parallel tracks that are interdependent but can be progressed simultaneously. Understanding the tracks and their dependencies is what allows founders to compress the timeline from the typical sequential approach to a properly parallelised project.

Tracks A and C can begin on Day 1, simultaneously. Track B can begin on Day 1 for DP selection and appointment, but the ISIN application cannot be submitted until the tripartite agreement is signed which requires the DP to be appointed. The ISIN allotment (2–3 weeks) runs in parallel with Track C shareholder coordination. DRF processing begins only after the ISIN is allotted and shareholder accounts are open.

Track A: ROC Compliance The Foundation Layer

Step A1: Audit All Historical Share Allotments

What: Pull every board resolution that authorised a share allotment, every subscription agreement, every PAS-3 return filed with the ROC, and every share certificate issued. Lay them side by side and confirm they are consistent.

Who: Company Secretary, supported by CA if records are incomplete.

Output: A complete allotment history table showing date, number of shares, share class, allottees, distinctive number range, PAS-3 reference number, and certificate numbers for each allotment.

What goes wrong: PAS-3 not filed within 30 days of allotment (a common compliance gap), distinctive numbers in certificates that do not match PAS-3, allotments for which no board resolution can be located. Each gap needs to be documented and remediated before the depository verification stage.

Step A2: Audit All Historical Share Transfers

What: For every share transfer that has occurred co-founder splits, secondary sales, gift transfers confirm a signed Form SH-4 (share transfer deed) exists, the consideration is documented, a board resolution approved the transfer, and the register of members reflects the post-transfer position.

Who: Company Secretary.

Output: A transfer history log showing each transfer with the transferor, transferee, share count, date, SH-4 reference, and board resolution date.

What goes wrong: Informal co-founder equity splits that were agreed verbally but never documented with SH-4 forms. Early secondary sales where the transfer was processed by the company but the physical certificate was never surrendered and reissued. Foreign investor transfers that required RBI approval under FEMA but were not reported.

Step A3: Confirm All PAS-3 Filings Are Current

What: Verify that a PAS-3 return was filed with the ROC within 30 days of every allotment. Late PAS-3 filings are a compliance breach they can be rectified with a condonation application and additional fees, but they need to be identified and resolved before due diligence begins.

Who: Company Secretary, with CA support for any late filings.

Output: Confirmation that every allotment has a corresponding PAS-3 on the MCA portal, with no outstanding late filings.

What goes wrong: ESOP exercise allotments that were processed informally the board resolution was passed and the shares were 'issued' to employees in the register, but the PAS-3 was never filed. This is a relatively common gap in early-stage startup ESOP administration and needs to be filed (late, with fees) before the depository will accept the corresponding DRFs.

Why ROC Filings Matter to the Depository

When a shareholder submits a Dematerialisation Request Form (DRF) for their physical share certificates, the company's Registrar and Transfer Agent (RTA) verifies the request against the company's records before confirming the electronic credit.

The RTA specifically checks:

• That the certificate number on the DRF matches the certificate number in the company's register
• That the distinctive number range on the certificate matches the PAS-3 allotment record
• That the shareholder's name on the DRF matches the register entry

If the PAS-3 was not filed or was filed with incorrect distinctive numbers, the RTA cannot verify the DRF. The dematerialisation request is rejected and the shareholder remains a physical shareholder until the ROC record is corrected.

This is the direct link between ROC compliance and depository access. Clean ROC filings are not just a regulatory obligation they are a practical prerequisite for demat.

Track B: Depository Setup The Infrastructure Layer

Step B1: Select and Appoint a Depository Participant

What: Evaluate DP options (bank DPs vs specialist registrar DPs), select based on experience with private company ISINs and fee structure, and execute the DP agreement.

Who: Founder decision, executed by Company Secretary.

Output: Signed DP agreement, DP client ID for the company.

Timeline: 3–5 business days from DP selection to signed agreement.

What goes wrong: Choosing a DP with no private company experience, leading to slower ISIN processing and more back-and-forth on document requirements. Ask any shortlisted DP for references from unlisted companies they have processed in the last six months.

Step B2: Execute the Tripartite Agreement

What: The tripartite agreement is signed between three parties the company (issuer), the Depository Participant, and the Registrar and Transfer Agent (RTA). This agreement governs how share transfers, allotments, and dematerialisation requests are processed between all three parties. It is a legal prerequisite for the ISIN application.

Who: Company (authorised director), DP, and RTA all three must sign.

Output: Executed tripartite agreement three original signed copies, one for each party.

Timeline: 3–7 business days, depending on RTA responsiveness.

What goes wrong: The company tries to use an RTA they have not formally appointed the agreement cannot be executed without a formal RTA engagement. Some early-stage startups have never formally appointed an RTA because their share volume was too small to require one. Appointing an RTA from scratch adds 1–2 weeks to this step.

Step B3: Apply for ISIN(s)

What: Submit the ISIN application package to NSDL or CDSL through the DP. One application per share class equity shares, CCPS, OCPS, and any other instruments each require a separate application submitted simultaneously.

Who: DP submits on behalf of the company; Company Secretary prepares the document package.

Output: ISIN application reference number(s) from the depository.

Timeline: Application submission 1 day. Depository processing 2–3 weeks.

What goes wrong: Incomplete document package causes rejection of the application, restarting the 2–3 week processing clock. The most common missing documents are: board resolution that does not specifically reference dematerialisation, distinctive number ranges that conflict with PAS-3 records, and MOA that does not reflect current authorised capital after a recent increase.

ISIN Application Document Package Complete Checklist

Company-level documents (same for all ISIN applications):

• Certificate of Incorporation (certified true copy)
• MOA and AOA (certified true copy, reflecting current authorised capital)
• Company PAN card
• Board resolution specifically authorising dematerialisation and DP appointment
• Authorised signatory list with specimen signatures
• Latest audited financial statements
• Executed tripartite agreement

Per share class documents (one set per ISIN application):

• Current register of members for that share class
• Latest PAS-3 for that share class
• Specimen share certificate for that class
• Distinctive number range details from and to numbers
• Face value and paid-up value confirmation
• Total number of shares outstanding in that class

Submit all applications on the same day do not wait for the first ISIN before applying for the second.

Step B4: Receive ISIN Allotment and Confirmation Letter

What: NSDL or CDSL allots the ISIN(s) and issues a formal allotment confirmation letter. This letter is the primary document investors request during due diligence to confirm demat has been initiated.

Who: DP receives and forwards to the company.

Output: ISIN allotment letter one per share class. File this immediately in the data room.

Timeline: 2–3 weeks from application submission.

What goes wrong: Nothing at this stage if the application was complete and correctly submitted. The only delays are application corrections if the depository requests additional documentation or corrections, the clock pauses until the response is submitted.

Track C: Shareholder Coordination The Execution Layer

Step C1: Map Every Shareholder and Their Demat Status

What: Create a complete shareholder matrix every person and entity in the register of members, their share count by class, their contact details, and their current demat account status (confirmed account, no account, NRI account needed, corporate account needed, unknown).

Who: Company Secretary, with founder involvement for direct outreach.

Output: Shareholder demat status matrix updated in real time as confirmations come in.

Timeline: Initial outreach Day 1. Status confirmations 1–3 weeks depending on shareholder responsiveness.

Step C2: Initiate Demat Account Openings for Shareholders Who Need Them

What: For every shareholder without a demat account, provide instructions for opening one. Resident Indian individuals standard demat account through any registered DP. NRI individuals NRO or NRE demat account through a bank with NRI services. Corporate entities demat account in the entity's name with appropriate KYC.

Who: Each shareholder opens their own account. Company Secretary provides instructions and DP recommendations. Founder follows up directly for non-responsive shareholders.

Output: Demat account details (DP name, DP ID, client ID) for each shareholder.

Timeline: Resident Indian 5–7 business days. NRI 3–6 weeks. Corporate 1–2 weeks.

What goes wrong: NRI shareholders who do not act urgently on the account opening request, adding weeks to the critical path. Assign the NRI account opening as a Day 1 priority and check progress every five days.

Step C3: Distribute and Collect Dematerialisation Request Forms

What: Once the ISIN is allotted and each shareholder has a demat account, distribute DRFs to all shareholders. Each shareholder completes the DRF which includes their DP details, demat account number, the certificate details they are submitting, and the number of shares and submits it along with their original physical share certificates to their DP.

Who: Each shareholder submits their own DRF to their own DP. Company Secretary tracks submissions.

Output: DRF submission confirmation from each DP. DRF reference numbers for tracking.

Timeline: DRF completion and submission 3–7 business days per shareholder. DRF processing by depository 7–15 business days.

What goes wrong: Shareholders cannot locate their physical certificates. Certificates have name or distinctive number discrepancies. RTA rejects the DRF due to a mismatch between the certificate and the register.

Step C4: Track DRF Processing and Resolve Rejections

What: Monitor every DRF through the depository system. Follow up on pending DRFs daily. Investigate and resolve any rejections within 24 hours of notification.

Who: Company Secretary, with DP support for system access.

Output: Electronic share credits in each shareholder's demat account, confirmed by the depository.

Timeline: 7–15 business days from DRF submission for standard processing. Rejections add 3–10 business days per rejection for investigation and resubmission.

Common DRF Rejection Reasons and Fixes

Rejection: Certificate number not found in company records
Fix: Verify certificate number against register; issue corrected certificate if number was issued incorrectly

Rejection: Name on certificate does not match PAN
Fix: Board resolution to correct name; reissue certificate; resubmit DRF

Rejection: Distinctive numbers do not match PAS-3
Fix: Identify the correct distinctive numbers from PAS-3; issue corrected certificate; resubmit

Rejection: PAS-3 not on MCA portal for this allotment
Fix: File late PAS-3 with condonation fees; await MCA processing; resubmit DRF

Rejection: Certificate appears to have been cancelled previously
Fix: Investigate whether a duplicate certificate was issued; confirm with register; escalate to legal if disputed

The Final Steps: Reconciliation and Ongoing Compliance

Step F1: Run the Full Register-to-Depository Reconciliation

What: Once all DRFs are processed and shares are credited, run a line-by-line reconciliation: every shareholder in the register must have an exactly matching demat holding. Share count, share class, and distinctive number ranges must all match. Any discrepancy is investigated and resolved before declaring the process complete.

Who: Company Secretary, with sign-off from the statutory auditor.

Output: Signed reconciliation statement confirming register and depository records are fully aligned.

What goes wrong: Minor discrepancies usually from rounding errors in distinctive numbers or instrument class mismatches that require investigation. Each unresolved discrepancy is a due diligence finding waiting to happen.

Step F2: Establish the Ongoing Demat Maintenance Protocol

What: Put processes in place for every future share event new investor allotments, ESOP exercises, secondary transfers, CCPS conversions to be processed in demat form from Day 1, with the depository updated simultaneously with the ROC filing.

Who: Company Secretary defines the protocol; founder approves and enforces.

Output: A written demat protocol document that specifies what the CS must do for each type of share event to keep the depository records current.

The core rule: After demat is complete, no physical share certificate is ever issued again. All new allotments go directly into shareholder demat accounts. Every share event generates both a ROC filing (PAS-3, SH-4) and a depository instruction simultaneously, not sequentially.

Step F3: Prepare the Investor Due Diligence Package

What: Compile the complete demat documentation package that will go into the Series A data room. Every document should be dated, current, and reconciled.

• ISIN allotment letter(s) one per share class
• Executed tripartite agreement
• Executed DP agreement
• Reconciled register of members current as of reconciliation date
• Depository holding statements for each shareholder within 30 days
• Board resolution authorising dematerialisation
• Confirmation that all post-mandate allotments were made in demat form

The Bottom Line

The demat process looks like a single task but it is really three parallel workstreams ROC compliance, depository infrastructure, and shareholder coordination that converge at the reconciliation stage. Each workstream has its own dependencies, its own failure modes, and its own timeline. Founders who treat demat as a project with three tracks, clear ownership, and daily progress tracking complete it in six to eight weeks. Founders who treat it as a single task that gets handed to the company secretary and checked on monthly complete it in four to six months and usually under investor pressure.

The ROC layer is the foundation. If your PAS-3 filings are clean and your distinctive number records are accurate, the depository verification runs smoothly. If they are not, every DRF rejection points back to a ROC gap that needs remediation. Start there. Everything else follows.

Frequently Asked Questions

Do we need to file anything with the ROC when dematerialisation is complete?

There is no specific ROC filing that marks the completion of dematerialisation for a private company. However, once demat is in place, every new allotment triggers a PAS-3 filing the same as before and every share transfer triggers an SH-4 documentation requirement. The difference is that post-demat, these transactions are also reflected in the depository system. The ROC and depository are two parallel record systems; demat completion does not replace ROC obligations, it adds a depository layer alongside them.

What is a Registrar and Transfer Agent and does every startup need one?

An RTA (Registrar and Transfer Agent) is a SEBI-registered entity that maintains the register of members and processes share transfers and dematerialisation requests on behalf of the company. Technically, for very small companies, the company secretary can act as an in-house registrar. In practice, for any startup that is processing demat, an appointed RTA is required because the tripartite agreement which is a prerequisite for the ISIN application must name an RTA as one of the three parties. Most startups appoint KFin Technologies, Bigshare Services, or Link Intime as their RTA.

Can we issue new shares in demat form before all existing shares have been converted from physical?

Yes. Once the ISIN is allotted, new share allotments can be made in demat form even if some existing shareholders still hold physical shares that have not yet been converted. The ISIN is the identifier for the share class it works for new allotments regardless of the conversion status of old allotments. This means a startup that is mid-way through demat can still close a funding round and issue new investor shares in demat form, while the physical conversion of existing shareholder certificates continues in parallel.

What happens to the physical share certificates after they are dematerialised?

Physical certificates that are surrendered for dematerialisation are forwarded to the company's RTA by the DP. The RTA verifies them, marks them as 'SURRENDERED FOR DEMATERIALISATION', and retains them as physical records. They are permanently cancelled they have no further legal standing as proof of ownership. The shareholder's demat account holding becomes the sole authoritative record of their ownership. The RTA retains the cancelled certificates for the statutory record retention period (typically 8 years) before disposal.

After demat is complete, how are ESOP exercise allotments processed?

When an employee exercises their vested options, the company passes a board resolution allotting the specified number of shares to the employee. The PAS-3 is filed with the ROC within 30 days. Simultaneously, the company instructs the DP to credit the allotted shares to the employee's demat account under the equity ISIN. The employee receives a demat credit in their account no physical certificate is issued. The exercise confirmation document (allotment letter) references both the PAS-3 allotment and the demat credit, giving the employee a complete paper trail of their ownership.
