Registrar and Transfer Agent (RTA): Role, Why You Need One and Fees

01What Is a Registrar and Transfer Agent (RTA)?

A Registrar and Transfer Agent (RTA) is a SEBI-registered intermediary that maintains the register of security holders on behalf of a company and acts as the interface between that company and the depositories. In India there are only two depositories, NSDL and CDSL, and an RTA is the entity that connects your company to them. The RTA full form is exactly that: registrar (it keeps the records) and transfer agent (it processes changes to those records).

Think of the RTA as the official record-keeper for your shareholders. When shares change hands, when new shares are allotted, when a shareholder dematerialises a physical certificate or when the company runs a corporate action like a bonus or a buyback, the RTA is the party that updates the register and reflects it in the electronic records held at the depository. For a company that is dematerialising its shares, this makes the RTA the single most important external partner in the process.

RTAs are licensed and regulated by SEBI, so they are not informal service providers. A handful of established firms handle most of the market: KFin Technologies, Link Intime (now MUFG Intime), Cameo, Bigshare and Skyline. A company appoints one of these as its RTA; individual investors, by contrast, never appoint an RTA, they deal with their own Depository Participant. We unpack that distinction next.

02RTA vs DP vs Depository: The Clear Distinction

This is where most founders get confused, so here is the clean version. Three different parties sit in the demat ecosystem, and each works for a different side. The depository is the central electronic vault, the Depository Participant (DP) is the investor’s agent, and the RTA is the company’s record-keeper. The table below lays them side by side.

The simplest way to remember it: a shareholder opens a demat account with a DP, the shares sit inside the depository, and the company’s records are kept by the RTA. When a shareholder dematerialises a certificate, the request travels from the DP, through the depository, to the RTA for confirmation, then back. For more on the two depositories, read our explainer on NSDL vs CDSL.

03What an RTA Does for Dematerialisation

For a private company going through demat, the RTA carries most of the operational load. These are the concrete tasks it handles from start to finish.

1. Applies for the ISIN

The RTA prepares and submits the ISIN application to NSDL or CDSL on the company’s behalf, with the Certificate of Incorporation, MOA and AOA, board resolution, audited financials, net-worth certificate, register of members and directors’ KYC. Each class or type of security gets its own ISIN, so the RTA applies separately for Equity Shares, each class of preference shares and any debentures. See our guide to getting an ISIN for the detail.

2. Signs the tripartite agreement

Dematerialisation requires a tripartite agreement between the company, the RTA and the depository. The RTA is a named party to this agreement and coordinates its execution, which is what formally plugs your company into the depository system.

3. Verifies and confirms dematerialisation requests

When a shareholder submits a Dematerialisation Request Form (DRF) to their DP, the request reaches the RTA. The RTA checks the certificate numbers, distinctive numbers, folio and quantity against the register of members. If everything matches, it confirms the request and the shares are credited to the shareholder’s demat account. A mismatch leads to rejection, so accurate records matter.

4. Processes corporate actions and maintains records

Bonus issues, rights issues, splits, buybacks and transfers all run through the RTA, which updates the register and reflects the change in the electronic holdings. The RTA is also the keeper of the ongoing register of security holders, which is the system of record for who owns what.

5. Helps with PAS-6 data

Companies covered by demat rules file a half-yearly PAS-6 (Reconciliation of Share Capital Audit Report) with the ROC. The RTA provides the reconciliation data on issued capital versus dematerialised holdings that feeds this filing, which the company’s CS or CA then certifies.

04Why a Private Company Must Appoint an RTA

The short answer: you cannot get an ISIN or run dematerialisation without an RTA. The depository does not deal directly with an unlisted issuer for ISIN allotment and demat confirmations; it works through a SEBI-registered RTA. So appointing one is not optional housekeeping, it is the gate you have to pass through.

This matters most for companies caught by Rule 9B of the Companies (Prospectus and Allotment of Securities) Rules. Every private company that is not a small company must issue securities only in dematerialised form and facilitate demat of its existing securities. A small company here means paid-up capital up to ₹4 crore and turnover up to ₹40 crore; cross either threshold and the rule bites. A holding or subsidiary company is never a small company, so it is in scope however small it is. The compliance deadline (extended to 30 June 2025) has already passed for affected companies, so if you are covered and not yet compliant, the practical first step is to appoint an RTA.

Without demat in place, a covered company also hits a wall on transactions: a holder cannot be allotted new shares, or receive bonus, rights or buyback shares, unless they are in demat form. In other words, an unappointed RTA can quietly freeze your cap-table activity. Appointing one early keeps you both compliant and able to transact.

05How to Choose an RTA (Who to Hire for Dematerialisation)

If you are asking who to hire for dematerialisation, the answer is a SEBI-registered RTA, and the work is in picking the right one. Most companies are coordinated into onboarding by their company secretary or finance adviser, but the choice is yours. Weigh these five factors.

• SEBI registration: non-negotiable. Only a SEBI-registered RTA can apply for an ISIN and act on a tripartite agreement. Confirm the registration before you sign.
• Experience with private and unlisted companies: listed-company RTAs are common, but unlisted demat has its own quirks (smaller folios, founder cap tables, ESOP allotments). Pick one that handles unlisted issuers routinely.
• Both NSDL and CDSL connectivity: an RTA connected to both depositories gives you flexibility on cost and on which depository your shareholders’ DPs use. Single-depository RTAs can box you in.
• Turnaround: ask for committed timelines on ISIN application and DRF confirmation. Slow confirmations stall funding rounds and frustrate shareholders.
• Fee transparency: get the one-time, annual and per-transaction charges in writing up front, so there are no surprises at renewal or at the next corporate action.

The established names you will most often shortlist are KFin Technologies, Link Intime (MUFG Intime), Cameo, Bigshare and Skyline. All are SEBI-registered and handle unlisted companies; differences come down to pricing, responsiveness and which depositories they serve well. Get two or three quotes before you commit.

06Typical RTA Fees in India

RTA fees come in three buckets: a one-time onboarding or ISIN-assistance charge, an annual maintenance fee, and per-transaction charges. As a guide, the annual maintenance fee runs roughly ₹3,000 to ₹30,000, depending on the RTA and your share capital, with per-DRF and per-corporate-action charges on top. These are commercial fees set by the RTA, so always get a written quote.

Crucially, RTA fees are only part of the bill. The depository charges its own one-time ISIN and joining fee (around ₹15,000), a refundable security deposit (minimum about ₹10,000, often linked to paid-up capital), and an annual custody or issuer fee (roughly ₹5,000 to ₹11,000). Each shareholder separately pays their DP’s account-opening and demat-request charges.
