Demat Account & Depository (NSDL/CDSL)

By Sneha Iyer | Updated March 2026

What Is a Demat Account?

A demat (dematerialized) account is an electronic account that holds securities — shares, bonds, mutual fund units, government securities, and ETFs — in digital form, replacing physical share certificates. Governed by the Depositories Act, 1996 and the SEBI (Depositories and Participants) Regulations, 2018, the demat system is operated by India's two central depositories: the National Securities Depository Limited (NSDL) and the Central Depository Services (India) Limited (CDSL). Investors open demat accounts through Depository Participants (DPs) — banks, stockbrokers, and custodians registered with SEBI.

For foreign companies and investors establishing a presence in India, a demat account is not optional — it is a regulatory necessity. SEBI mandates that all shares of listed companies be held and transferred in dematerialized form. Since 2023, the Ministry of Corporate Affairs (MCA) has extended this requirement to unlisted public companies and most private companies through Rule 9B of the Companies (Prospectus and Allotment of Securities) Rules. Whether you are incorporating a wholly-owned subsidiary, acquiring shares in a listed Indian target, or receiving shares through a joint venture, you will need a demat account.

Legal Basis

• Depositories Act, 1996 — The foundational statute enabling the creation of depositories and the dematerialization of securities in India. Sections 4-12 govern depository registration, participant regulation, and investor rights.
• SEBI (Depositories and Participants) Regulations, 2018 — Replaced the 1996 regulations. Governs registration and operations of depositories and DPs, including KYC, account opening, transfer procedures, and investor grievance redressal.
• Companies Act, 2013 (Section 29) — Mandates that public companies making offers of securities must issue them only in dematerialized form.
• Rule 9B, Companies (Prospectus and Allotment of Securities) Rules — Inserted in October 2023. Mandates that all private companies (except small companies with paid-up capital under INR 4 crore and turnover under INR 40 crore) must issue securities only in dematerialized form. Existing physical certificates must be converted by June 30, 2025.
• SEBI Circular (SEBI/HO/MRD/MRD-PoD-2/P/CIR/2025/10) — Mandates T+1 settlement cycle for all trades on recognized stock exchanges, effective since January 2024.

NSDL vs CDSL: India's Two Depositories

India operates a dual-depository system. Both are SEBI-registered, government-regulated, and offer identical core services. The choice between them depends on which depository your DP is registered with.

Together, NSDL and CDSL hold over 19.24 crore (192.4 million) demat accounts as of 2025 — a 27% increase from the previous year. Both offer the same core services: dematerialization, rematerialization, trade settlement, share pledging, and electronic processing of corporate actions (dividends, bonuses, rights issues).

How to Open a Demat Account

For Resident Indians and Indian Companies

1. Select a Depository Participant (DP) — Choose a SEBI-registered bank, broker, or custodian. The DP determines which depository (NSDL or CDSL) your account is with.
2. Complete KYC — Submit PAN card, Aadhaar (for e-KYC via DigiLocker), address proof, bank account details, and passport-size photograph. E-KYC takes approximately 10 minutes.
3. Sign the DP-client agreement — Governs the terms of account operation, charges, and nominee details.
4. Receive your client ID — Your unique demat account number (BO ID for NSDL, 16-digit ID for CDSL).
5. Link trading and bank accounts — Connect your demat account to a trading account (for buy/sell orders) and a bank account (for fund transfers).

For NRIs and Foreign Investors

Non-resident Indians and foreign nationals can open demat accounts in India, but with specific requirements:

Key requirements for NRI demat accounts:

• PIS permission — NRIs must obtain Portfolio Investment Scheme approval from a designated authorized dealer bank before trading in the secondary market
• Separate accounts — RBI requires NRIs to maintain two separate demat accounts — one linked to NRE (repatriable) and one linked to NRO (non-repatriable)
• FEMA compliance — All investments must comply with FEMA regulations and FDI sectoral caps
• Tax implications — Capital gains tax and TDS apply to NRI share transactions, with DTAA benefits available depending on the country of residence

Mandatory Dematerialization: Current Requirements

Listed Companies

All shares of listed companies must be held in demat form. SEBI mandated 100% dematerialization for listed company shares decades ago. Physical share certificates of listed companies cannot be transferred — they must first be dematerialized.

Unlisted Public Companies

Under Rule 9A of the Companies (Prospectus and Allotment of Securities) Rules, every unlisted public company must:

• Issue securities only in dematerialized form
• Facilitate dematerialization of all existing securities
• Obtain an ISIN from NSDL or CDSL
• File half-yearly returns in Form PAS-6 with the Registrar of Companies

Private Companies (Rule 9B — October 2023)

The most significant recent development is MCA's mandate for private company dematerialization:

• Covered companies: All private companies except small companies (paid-up capital under INR 4 crore AND turnover under INR 40 crore) and government companies
• Compliance deadline: September 30, 2024 (extended to June 30, 2025 for companies with non-March year-ends)
• Requirements: Amend AoA, appoint SEBI-registered RTA, obtain ISIN, ensure all promoters/directors/KMP dematerialize their holdings, file PAS-6 semi-annually
• Impact on foreign-held companies: If your Indian subsidiary is a private company with paid-up capital above INR 4 crore or turnover above INR 40 crore, it must comply with Rule 9B

ISIN: The Unique Security Identifier

Every dematerialized security is identified by an ISIN (International Securities Identification Number) — a 12-character alphanumeric code. Indian ISINs follow the format INE + 9 characters (e.g., INE002A01018 for Reliance Industries equity shares). A company needs a separate ISIN for each type of security (equity shares, preference shares, debentures, etc.). ISINs are allotted by NSDL or CDSL upon application by the company through its RTA.

Account Maintenance and Charges

The Basic Demat Account (BDA) is a SEBI initiative for small investors: if your total holding value is under INR 2,00,000, the AMC is waived entirely. If the value is under INR 50,000, no charges apply at all.

How This Affects Foreign Investors in India

• Subsidiary share issuance: When you incorporate a private limited company in India and issue shares, those shares must be dematerialized if the company exceeds the small company threshold. You need an ISIN from NSDL/CDSL and an RTA before the first share allotment.
• FDI share acquisition: When a foreign investor acquires shares in an Indian company (listed or unlisted), the shares are credited to a demat account. The FC-GPR filing with RBI references the demat account details.
• NRI portfolio investment: NRIs investing in Indian equities under the Portfolio Investment Scheme must operate through an NRE-linked demat account for repatriable investments. Dividends and sale proceeds are freely repatriable through the NRE account.
• Repatriation of sale proceeds: Proceeds from selling shares held in an NRO demat account are repatriable up to USD 1 million per financial year, subject to tax clearance (Form 15CA/15CB certification).
• No stamp duty on demat transfers: One overlooked advantage — transfers of dematerialized shares attract zero stamp duty, unlike physical share transfers which attract state-level stamp duties. This reduces acquisition costs for foreign investors.

Common Mistakes

• Assuming a single demat account works for both repatriable and non-repatriable NRI investments. RBI requires NRIs to maintain separate NRE-linked and NRO-linked demat accounts. Mixing repatriable and non-repatriable shares in one account creates FEMA compliance issues and can block repatriation of legitimate proceeds.
• Not obtaining an ISIN before allotting shares in a private company. Under Rule 9B, covered private companies must obtain an ISIN and appoint an RTA before issuing new shares. Many foreign-held Indian subsidiaries allot shares first and attempt to dematerialize later, which violates the regulation and complicates the ROC filing process.
• Overlooking the PAS-6 semi-annual filing requirement after dematerialization. Once a company obtains an ISIN and enables dematerialization, it must file Form PAS-6 with the ROC every six months, reporting the reconciliation of share capital. Missing this filing attracts penalties and flags the company in MCA's compliance system.
• Choosing a DP without considering NRI/foreign investor servicing capability. Not all depository participants serve NRI or foreign corporate clients. Some DPs lack the infrastructure for PIS integration, FEMA documentation, and TDS compliance. Selecting the wrong DP causes delays in account opening and trade settlement.
• Failing to update nominee details when foreign shareholders change. SEBI mandates nomination for all individual demat accounts. When a foreign holding company transfers its Indian subsidiary's shares to a different group entity, the demat account must be updated — including KYC, nominee details, and PAN/tax status. Failing to update can freeze the account.

Practical Example

Horizon Technologies BV, a Dutch company, incorporates a wholly-owned subsidiary in India — Horizon India Pvt Ltd — with an authorized capital of INR 10 crore and initial paid-up capital of INR 5 crore (50,000 shares at INR 1,000 each). Since the paid-up capital exceeds INR 4 crore, Rule 9B applies.

Step 1 — Appoint RTA: Horizon India appoints Link Intime India Pvt Ltd (SEBI-registered RTA) at an annual fee of approximately INR 15,000.

Step 2 — Obtain ISIN: Link Intime applies to NSDL for an ISIN. Horizon India receives ISIN INE123X01012 within 7-10 working days. One-time ISIN activation fee: INR 8,000 (NSDL) + RTA processing charges.

Step 3 — Open demat account: Horizon Technologies BV (the foreign shareholder) opens a demat account through HDFC Bank as DP (one of the few DPs servicing foreign corporate clients). KYC documentation includes the company's Dutch incorporation certificate (apostilled), board resolution, PAN of the Indian subsidiary, and authorized signatory details. Account opening takes approximately 2-3 weeks for foreign entities.

Step 4 — Share allotment in demat form: 50,000 equity shares are allotted to Horizon Technologies BV and credited directly to its demat account. The company files FC-GPR with the RBI within 30 days, referencing the demat account number and ISIN.

Step 5 — Ongoing compliance: Horizon India files PAS-6 every six months with the ROC. Annual maintenance charge for the demat account: approximately INR 500 per year. When Horizon India later issues additional shares (say, INR 3 crore in a rights issue), the new shares are allotted directly in demat form — no physical certificates involved.

Cost saving: Had the shares been in physical form, a subsequent transfer to another group entity would attract stamp duty of 0.25% (INR 1.25 lakh on INR 5 crore). In demat form, the transfer is stamp-duty-free — saving INR 1.25 lakh on the initial holding alone.

Key Takeaways

• A demat account holds securities in electronic form through NSDL or CDSL, accessed via a SEBI-registered Depository Participant
• SEBI mandates dematerialization for all listed company shares; MCA's Rule 9B (October 2023) extends this to most private companies with a June 30, 2025 compliance deadline
• NRIs must maintain separate NRE-linked (repatriable) and NRO-linked (non-repatriable) demat accounts with PIS approval from an authorized dealer bank
• Annual maintenance charges range from INR 0 (Basic Demat Account) to INR 900 per year; DP transaction charges are INR 13.50-25+ per sell transaction
• Foreign companies incorporating Indian subsidiaries need an ISIN, an RTA, and a demat account before allotting shares if they exceed the small company threshold
• Demat share transfers are stamp-duty-free, creating significant cost savings compared to physical certificate transfers
