NSDL Demat Accounts, CAS Statements, and the CDSL Difference
National Securities Depository Limited (NSDL) is a central securities depository registered with the Securities and Exchange Board of India. It maintains electronic records of securities held in NSDL Demat accounts across the Indian capital markets. When you hold listed shares, debentures, or exchange-traded funds in an NSDL Demat account, ownership is maintained through electronic book entries rather than physical certificates.
Many people searching for NSDL are looking for official portal links, checking their Consolidated Account Statement (CAS), or tracking a PAN card application. NSDL the depository handles securities records and Demat accounts. In contrast, PAN card applications and Tax Information Network operations are handled by Protean eGov Technologies Limited and UTIITSL.

What is a depository and what does NSDL do?
A securities depository is an institution that holds financial assets in electronic format and facilitates paperless book-entry transfers. It functions much like a commercial bank. A commercial bank maintains cash balances and transfers deposits via electronic ledgers. A depository maintains electronic records of securities and transfers legal entitlement between buyers and sellers.
NSDL was established in August 1996 as India’s first depository following the enactment of the Depositories Act, 1996. It was promoted by the National Stock Exchange (NSE), Industrial Development Bank of India (IDBI), and Unit Trust of India (UTI).
The core operational functions of NSDL include:
Dematerialization: Converting physical paper security certificates into electronic balances held in a Demat account.
Rematerialization: Converting electronic security balances back into physical paper certificates when requested by an account holder.
Electronic Settlement: Processing trade transfers between buyers and sellers following stock exchange execution.
Corporate Actions Processing: Crediting bonus shares, stock splits, and rights entitlements based on corporate announcements.
Pledging Facilities: Marking liens on electronic holdings to support loan or margin facilities, where supported by your Depository Participant.
Investors do not open accounts directly at NSDL headquarters. Instead, account holders access NSDL services through intermediaries called Depository Participants (DPs), including stockbrokers, custodian banks, and commercial banks.
It is important to understand the boundary between Demat holdings and mutual fund units. While mutual fund units can be dematerialized into an NSDL Demat account, open-ended mutual funds purchased in Statement of Account (SOA) form remain recorded in fund folios maintained by Registrar and Transfer Agents. They are not automatically held in an NSDL Demat account unless you deliberately purchase them in dematerialized form.

NSDL vs CDSL: understanding India's two depositories
India has two central securities depositories: National Securities Depository Limited (NSDL) and Central Depository Services (India) Limited (CDSL). Both depositories are regulated by the Securities and Exchange Board of India under the Depositories Act, 1996.
Understanding how they compare clarifies operational differences:
NSDL vs CDSL: Key Differences
| Operational Parameter | National Securities Depository Limited (NSDL) | Central Depository Services (India) Limited (CDSL) |
|---|---|---|
| Establishment & History | Established and incorporated in August 1996. Received its certificate of commencement in February 1999 and commenced operations in July 1999. | Established as a securities depository in India; the supplied source does not specify the establishment dates. |
| Founding Promoters & Sponsors | Promoted by NSE, IDBI, and Unit Trust of India. | Promoted by BSE, with major commercial banks acting as sponsors and shareholders. |

Why You Rarely Choose Between Them
Retail investors rarely select their depository directly. When you open an account with a stockbroker or bank, the Depository Participant determines whether your account sits with NSDL or CDSL. Many institutional and bank-affiliated brokerages connect through NSDL, while several discount brokers connect through CDSL.
For individual investors, operational standards are set by SEBI regulations. Both depositories execute transactions across the National Stock Exchange and BSE India. A share purchased on the NSE can settle into a CDSL account, and a share bought on the BSE can be credited to an NSDL account.

Trade settlement and legal ownership structure
In January 2023, India completed the rollout of the T+1 rolling settlement cycle for all listed equity cash-market transactions. In addition, SEBI has introduced an optional T+0 settlement cycle alongside T+1 for eligible liquid equity securities and participating brokers.
Under standard T+1 settlement, trade obligations settle within one business day after market execution:
Stock Exchange Trade Settlement Process
The process relies on coordination between market institutions:
Trade Execution (T Day): You purchase shares through your registered stockbroker.
Clearing Corporation Payout: The stock exchange clearing corporation manages the payout of funds and securities. Under direct client payout rules, securities are transferred directly from the clearing corporation to the client Demat account. The published payout window on major exchanges targets completion by 3:30 PM on T+1 day, with exact credit timing depending on clearing schedules.
Depository Processing: The depository processes the electronic credit into your specific Demat account.
Understanding Registered Owner vs Beneficial Owner
The legal nature of depository ownership is defined under Section 10 of the Depositories Act, 1996.
Under direct statute, the depository is deemed to be the registered owner in the records of the issuing company for the purpose of effecting transfers. The investor is recorded as the beneficial owner in the records maintained by the depository.
As the beneficial owner, you hold all economic rights, dividend entitlements, voting powers, and bonus allocations attached to those securities. The issuing company references NSDL beneficiary records on corporate record dates to disburse dividend payouts and corporate benefits directly to investors.
If you subsequently transfer listed equity shares held for 12 months or less, net qualifying gains face a 20 percent flat tax under Section 196 (formerly Section 111A) of the Income-tax Act, 2025. If held for more than 12 months, qualifying gains exceeding the aggregate threshold of ₹1,25,000 are taxed at 12.5 percent under Section 198 (formerly Section 112A). For complete details, review our blog on long term capital gain tax on shares.
Consolidated Account Statement (CAS): your unified ledger
The Consolidated Account Statement (CAS) is a single financial statement that aggregates investment records linked to the same Permanent Account Number (PAN).
Introduced under SEBI circulars, CAS eliminates the administrative burden of tracking multiple individual statements across brokers and asset management companies. It serves as an independent cross-check against statements received from distributors and brokers.
What Records Appear in an NSDL CAS?
An NSDL Consolidated Account Statement provides consolidated reporting across supported asset categories:
Demat Holdings: Listed equities, corporate debentures, government securities, and exchange-traded funds held across NSDL and CDSL accounts.
Mutual Fund Units in SOA Form: Open-ended mutual fund folios held in Statement of Account form with RTAs (CAMS and KFin Technologies).
National Pension System (NPS): Linked Tier I and Tier II retirement balances where mapped to the verified PAN.
e-Insurance Account (eIA) Details: Qualifying electronic insurance policy records held inside registered insurance repositories.
CAS is a consolidated statement for supported investment holdings, not an exhaustive summary of an individual’s complete net worth. It does not record physical real estate, bank fixed deposits, Public Provident Fund balances, or physical gold.

Dispatch Deadlines and Sender Rules
Under SEBI regulatory circulars, CAS dispatch timelines distinguish between electronic delivery and physical paper statements:
Monthly Statement Delivery: If an investor conducts any transaction in their Demat account or mutual fund folios during a calendar month:
Electronic CAS (e-CAS): Sent by the 12th day of the following month.
Physical CAS: Dispatched by the 15th day of the following month.
Half-Yearly Statement Delivery: If no transactions took place during a six-month period, but you maintain positive security balances:
For the period ending September: e-CAS is sent by 18 October, and physical CAS by 21 October.
For the period ending March: e-CAS is sent by 18 April, and physical CAS by 21 April.
Consolidation is executed using your PAN (and for joint holdings, the first holder’s PAN and exact holding pattern).
Where an investor maintains Demat accounts across both NSDL and CDSL, the depository where the earlier-opened account exists acts as the default CAS sender. An investor can change this preference by submitting a request through their Depository Participant. If you hold mutual funds in SOA form without any Demat account, the statement is dispatched by the RTAs.
Downloading and accessing your NSDL e-CAS
An electronic CAS is delivered as a digitally signed PDF to your registered email address. You can also download statements on demand through the official NSDL CAS portal.
Official Step-by-Step Portal Workflow
To download an on-demand statement through the NSDL CAS Portal:
Navigate to the CAS portal and select the download or subscription option.
Enter your 9-digit CAS ID and your 10-character PAN.
If your CAS ID is unknown, select the alternative option: enter your PAN, select your Depository Participant name, and enter your DP ID and Client ID.
Complete the verification captcha and submit the request.
Authenticate using the One-Time Password (OTP) sent to your registered mobile number and email.
Download the generated e-CAS statement for the selected period.
Opening the Password-Protected PDF
To safeguard sensitive financial data, every NSDL e-CAS PDF is protected by an automated password.
Under NSDL operational guidelines, the password to open the file is the 10-character Permanent Account Number (PAN) of the sole or first account holder entered in CAPITAL letters (for example, ABCDE1234F). Do not insert spaces or special symbols.
NSDL Depository vs Protean: clearing up PAN confusion
A frequent query involves checking PAN application statuses on NSDL portals. This confusion stems from historical corporate identity changes.
Historically, the company operating the depository managed an infrastructure entity called NSDL e-Governance Infrastructure Limited. That company handled government projects, including the Tax Information Network (TIN) and PAN application processing.
In December 2021, NSDL e-Governance Infrastructure formally rebranded as Protean eGov Technologies Limited. Protean is a distinct corporate entity, not an internal operational branch of the securities depository.
The operational distinction is clear:
National Securities Depository Limited (NSDL): The securities depository holding Demat accounts, electronic shares, and CAS records.
PAN Service Providers (Protean and UTIITSL): Authorized service providers that process PAN applications, corrections, and card reprints.
Income Tax Department Portal: The government platform for filing annual income tax returns, viewing Form 26AS, and checking tax assessments.
If you need to apply for a PAN card or check dispatch status, submit your inquiry through Protean or UTIITSL rather than the NSDL depository website.
Online monitoring tools: IDeAS, SPEED-e, and e-Voting
NSDL provides online access tools that allow investors to track holdings and authorize transactions:
1. IDeAS (Internet-based Demat Account Statement)
IDeAS provides view-only web access to your NSDL Demat account.
Under NSDL published service guidelines, registered users can view transactions executed within the previous 30 days and download month-wise transaction statements for up to the previous 12 months. Holding valuations are updated based on the previous business day’s closing prices; account information is online but not real-time.
2. SPEED-e Facility
SPEED-e is an internet infrastructure that enables account holders to submit delivery instructions electronically rather than filling out physical paper Delivery Instruction Slips (DIS).
However, SPEED-e is not universally available to every NSDL Demat holder. It can only be used if your specific Depository Participant has subscribed to the SPEED-e service.
3. NSDL e-Voting Services
NSDL operates the NSDL e-Voting System to facilitate electronic voting on corporate shareholder resolutions.
This service allows shareholders holding shares in physical or Demat form (across either NSDL or CDSL) to cast electronic votes on shareholder ballots directly using their credentials.
What happens to your holdings if a broker or DP closes?
A frequent concern among investors is what happens if a stockbroker or Depository Participant experiences business failure.
The legal framework provides structured protection:
Securities already credited to your Demat account remain your legal beneficial property.
Your stockbroker or bank acts as a Depository Participant, serving as an intermediary connecting you to the central depository. Your electronic holdings sit recorded in your personal Demat account within the depository system:
If a broker or DP closes business, securities fully credited to your Demat account cannot be attached by the intermediary’s commercial creditors.
Under NSDL operational procedures, if a Depository Participant ceases operations, account holders can transfer their balances to another active DP or submit a request to rematerialize their securities.
However, unsettled trade positions, funds sitting in a broker’s trading pool account, or securities yet to be transferred out of a broker’s collateral account are subject to standard exchange clearinghouse resolution procedures.
Maintaining regular oversight of your CAS records ensures that executed transactions have been properly credited to your own beneficial Demat account.
Common Questions
Both NSDL and CDSL are regulated by SEBI under the Depositories Act, 1996. Both depositories operate under uniform regulatory standards, mandatory data recovery protocols, and regular supervisory inspections.
Enter the 10-character PAN of the sole or first account holder in CAPITAL letters without spaces or special symbols.
An NSDL Demat account number is a 16-character alphanumeric identifier. It begins with the two letters “IN” followed by a 6-digit Depository Participant ID (DP ID), combined with your 8-digit client identifier.
Under SEBI regulations, electronic CAS (e-CAS) is emailed by the 12th day of the following month for accounts with transactions, while physical paper statements are dispatched by the 15th day.
Yes. India’s depository infrastructure is interoperable across exchanges. Shares bought on the BSE can settle into an NSDL Demat account, and shares bought on the NSE can settle into a CDSL account.
