Annual Maintenance Charges on a Demat account are one of those recurring costs that quietly leave your bank account every year, whether you actively invest or not. For small investors just starting out, or those who hold a modest portfolio and transact infrequently, paying ₹300 to ₹800 annually simply to maintain an account can feel disproportionate to the value received.
SEBI anticipated this problem and created a solution — the Basic Services Demat Account, or BSDA. It’s specifically designed for small investors, carries significantly lower charges, and in many cases costs absolutely nothing to maintain. The surprising part is that millions of eligible investors are either unaware it exists or have never been moved to this account type despite qualifying for it.
That changes today.
What Is a BSDA?
A Basic Services Demat Account is a simplified, low-cost variant of the standard Demat account introduced by SEBI to make market participation more affordable for retail investors with smaller portfolios. The fundamental premise is straightforward — an investor holding modest securities should not pay the same maintenance charges as someone holding a large, actively traded portfolio.
BSDA offers all the core functionalities of a regular Demat account. You can hold equity shares, mutual fund units, ETFs, bonds, government securities, and sovereign gold bonds. You can buy, sell, and transfer securities. You receive corporate action benefits like dividends and bonus shares. There is no restriction on the types of securities you can hold or the transactions you can execute.
The only structural difference is the cost — and for eligible investors, that difference is significant.
The AMC Structure Under BSDA
SEBI’s updated BSDA framework, with the most recent amendments effective March 31, 2026, defines the Annual Maintenance Charge structure as follows.
If the total value of your Demat holdings is zero — meaning the account is open but holds no securities — the AMC is nil. No charge whatsoever for maintaining an empty account.
If your total holding value is above zero but does not exceed ₹4 lakh, the AMC remains nil. You pay nothing annually as long as your portfolio stays within this range.
If your holding value is between ₹4 lakh and ₹10 lakh, a modest AMC applies — typically in the range of ₹100 to ₹150 per year, though the exact amount is determined by the Depository Participant within SEBI’s prescribed limits.
Once your holdings exceed ₹10 lakh, the account is no longer eligible for BSDA status and is converted to a regular Demat account with standard AMC applicable from that point.
For a first-time investor or someone building a portfolio steadily over time, this framework means years of zero maintenance cost before the portfolio grows to a size where standard charges become applicable.
The 2026 Update: DPs Must Convert Eligible Accounts by Default
This is the part that significantly changes the landscape for existing Demat account holders.
SEBI’s March 2026 amendment mandated that Depository Participants must now identify all existing accounts that qualify for BSDA status and convert them automatically — without the investor needing to ask. Additionally, all new accounts opened for investors who qualify must be set up as BSDAs by default.
If you are an eligible investor who has been sitting in a regular Demat account paying full AMC, your DP is now obligated to switch you over. You don’t need to initiate this — it should happen through a mandated quarterly review process.
However, if you are an eligible investor who prefers to retain a regular Demat account for any reason — perhaps because your broker offers additional services tied to regular account status — you can provide explicit consent to opt out of the BSDA conversion. This consent must be submitted through a verified and authenticated channel as prescribed by the depository.
The practical implication: if you haven’t heard from your broker about this, it’s worth checking your account type in your profile settings or contacting support directly.
The Eligibility Conditions You Must Meet
BSDA eligibility is subject to three core conditions that must all be satisfied simultaneously.
First, you must be an individual investor. Entities such as companies, partnerships, HUFs, and trusts are not eligible for BSDA.
Second, you must hold only one Demat account across both depositories — NSDL and CDSL combined. If you hold two Demat accounts, even with different brokers, neither qualifies for BSDA. You can hold multiple accounts, but only one can be designated as a BSDA, and only if the total value across all your accounts stays within the prescribed limits.
Third, the total value of holdings in your BSDA must not exceed ₹10 lakh at any point. DPs are now required to review this eligibility every quarter based on the daily closing price or NAV of your securities. If your portfolio value crosses ₹10 lakh at any review point, the account is converted to a regular Demat account automatically.
How Holding Value Is Calculated
SEBI has provided specific guidance on how DPs calculate the value of holdings for BSDA eligibility purposes.
For listed and actively traded securities, the daily closing price is used. For mutual fund units, the NAV is used. For illiquid securities — those that rarely trade — the last available closing price is taken into account. For unlisted securities other than mutual fund units, face value is used as the basis.
Importantly, the 2026 amendment specifically removed delisted securities and zero coupon zero principal bonds from the valuation calculation. These are excluded entirely from the holding value threshold — which can be meaningful for investors holding securities from companies that have been delisted.
What You Should Do Right Now
If you’re an individual investor with a single Demat account and holdings below ₹10 lakh, check whether your account is currently classified as a BSDA. This information is available in your account profile on your broker’s platform, or you can check your latest account statement.
If your account is still classified as a regular Demat account and you’re paying full AMC despite being eligible, contact your broker’s customer support and request a review. Under the 2026 mandate, they are required to convert your account — you are simply reminding them to fulfil an obligation that already exists.
If you’re opening a new Demat account and expect your portfolio to stay below ₹10 lakh for the foreseeable future, confirm at the time of account opening that the account is being opened as a BSDA. This is now the default for eligible investors, but confirming it upfront avoids any administrative ambiguity.
Frequently Asked Questions (FAQs)
Q1. Does switching to BSDA affect my ability to apply for IPOs or invest in mutual funds?
Not at all. BSDA offers the complete functionality of a standard Demat account. IPO applications, mutual fund investments in Demat form, ETF trading, equity delivery purchases — everything works identically. The only difference is the reduced or zero AMC. There is no restriction on the type or frequency of transactions.
Q2. What happens if my portfolio value temporarily crosses ₹10 lakh due to a market rally and then falls back below?
Your DP reviews BSDA eligibility every quarter. If your portfolio value crosses ₹10 lakh at the review date, your account is reclassified as a regular Demat account and standard AMC becomes applicable from that point. If the value subsequently falls below ₹10 lakh at a later review, your DP is required to convert the account back to BSDA status. This reclassification process is managed by the depository infrastructure and should happen automatically.
Q3. I have accounts with two different brokers. Can either of them be a BSDA?
No. BSDA eligibility requires that you hold only one Demat account across all depositories combined. If you hold accounts with two brokers — even if both are with the same depository — you don’t meet the single-account requirement. To qualify for BSDA, you would need to close one account and consolidate your holdings into a single Demat account.
Q4. Are there any services or features that are unavailable in a BSDA compared to a regular account?
SEBI mandates that BSDA holders receive all basic depository services. However, some brokers may tie premium features — such as margin trading facilities, advanced research tools, or priority customer support — to regular account status. These are broker-level features, not depository-level restrictions. Confirm with your specific broker whether any platform features change upon BSDA conversion.
Q5. Is there a formal process to apply for BSDA, or does it happen automatically?
Following the 2026 SEBI amendment, eligible investors should be converted to BSDA automatically by their Depository Participant without needing to apply. However, if you believe you qualify and haven’t been converted, you can proactively contact your broker and request the reclassification. Providing your account details and confirming that you hold only one Demat account across all depositories is typically sufficient for the broker to process the conversion.
