Basic Services Demat Account (BSDA) Rules (2026): Zero AMC Demat for Small Investors Under SEBI's New ₹4 Lakh to ₹10 Lakh Limits
Core Highlights of the Revised 2026 BSDA Framework
- 8x Increase in Zero-AMC Limit: SEBI raised the nil-AMC threshold from the historical ₹50,000 limit to an expansive ₹4,00,000, shielding millions of small investors from recurring account fees.
- ₹100 Capped AMC Tier: Holdings between ₹4 Lakh and ₹10 Lakh are capped at a nominal ₹100 per year, compared to commercial Demat AMCs of ₹300 to ₹900.
- Single Demat Requirement: The investor must hold only one Demat account across all depositories (CDSL and NSDL) combined where they are the sole/first account holder.
- Full Functional Parity: BSDA accounts can apply for all mainboard and SME IPOs via ASBA, trade secondary market equities, invest in mutual funds, and hold government bonds without restriction.
1. The Evolution of BSDA: Why SEBI Transformed Small Investor Accounts
For years, a major hurdle preventing middle-class Indians from entering the equity markets was the burden of fixed Annual Maintenance Charges (AMC). Traditional bank-backed and discount brokers routinely levy ₹300 to ₹900 annually plus 18% GST simply to maintain a Demat ledger, even if an investor holds just ₹25,000 worth of shares.
To eliminate this barrier, the Securities and Exchange Board of India (SEBI) originally established the Basic Services Demat Account in 2012. However, the original threshold of ₹50,000 for zero AMC quickly became outdated as stock markets appreciated.
Recognizing this limitation, SEBI issued Circular SEBI/HO/MIRSD/MIRSD-PoD1/P/CIR/2024/91, superseding previous limits and introducing a modern two-tier structure that went live in late 2024 and governs all Demat participants through 2026.
2. Old vs. New SEBI BSDA Slabs: The Complete Comparison
The structural overhaul enacted by SEBI fundamentally changes the economics of retail investing. Here is how the previous and current frameworks compare:
| Portfolio Valuation Range | Historical SEBI Slabs (Pre-2024) | Revised 2026 SEBI Slabs (Current) | Commercial Demat Comparison |
|---|---|---|---|
| Up to ₹50,000 | ₹0 (Nil AMC) | ₹0 (Nil AMC) | ₹300 to ₹600 + GST |
| ₹50,001 to ₹2,00,000 | ₹100 + GST | ₹0 (Nil AMC) | ₹300 to ₹600 + GST |
| ₹2,00,001 to ₹4,00,000 | Full Commercial AMC | ₹0 (Nil AMC - 100% Free) | ₹350 to ₹900 + GST |
| ₹4,00,001 to ₹10,00,000 | Full Commercial AMC | Capped at ₹100 + GST | ₹350 to ₹900 + GST |
| Above ₹10,00,000 | Full Commercial AMC | Full Commercial AMC | Standard Broker Tariff |
Unified Equity & Debt Valuation
Under the revised framework, SEBI removed the separate, complicated valuation limits for equity and debt securities. Now, your total portfolio—including equity shares, mutual funds, ETFs, corporate bonds, and Sovereign Gold Bonds (SGBs)—is aggregated into a single valuation metric against the ₹4 Lakh and ₹10 Lakh limits.
3. Eligibility Criteria for Opening or Converting to a BSDA Account
Not every Demat account automatically qualifies for BSDA status. SEBI mandates strict verification checks to ensure the facility benefits genuine small investors rather than institutional high-net-worth accounts:
- Single Demat Account Condition: The investor must hold only ONE Demat account across both central depositories (CDSL and NSDL) where they are named as the primary/sole holder. If you have an active account with Broker A and open an account with Broker B, neither will qualify for BSDA.
- Sole / First Holder Status: In joint Demat accounts, only the first holder's PAN is evaluated. If the first holder has another Demat account elsewhere, the joint account cannot be a BSDA.
- Portfolio Valuation Cap: The aggregate market value of all securities held in the account must not exceed ₹10,00,000 on the date of billing review.
- Electronic Statements Mandatory: To qualify for ₹0 AMC, the account holder must opt for electronic transaction statements (e-CAS) delivered via email. Physical paper statements attract a statutory printing fee of ₹25 per statement.
4. Detailed Breakdown of the Revised BSDA Slabs
Slab 1: Portfolio Value Up to ₹4,00,000 (The Zero AMC Tier)
This is the sweet spot for retail investors, students, long-term buy-and-hold SIP accumulators, and family accounts used primarily for IPO bidding:
- Annual Fee: Exactly ₹0 (No hidden account keeping fees).
- Statements: Free electronic delivery of holding statements and transaction ledgers.
- SMS Alerts: Standard CDSL/NSDL transaction and debit alerts are provided free of charge.
- Ideal For: Investors building an initial stock portfolio or maintaining independent PAN accounts for family members under SEBI IPO rules. Read our Family PAN Allotment Strategy Guide.
Slab 2: Portfolio Value ₹4,00,001 to ₹10,00,000 (The ₹100 Capped Tier)
When your investments grow beyond ₹4 Lakhs due to regular investing or market appreciation:
- Annual Fee: Capped by SEBI at a maximum of ₹100 per annum plus 18% GST (Total ₹118/year).
- Savings vs Commercial: Most full-service banks charge ₹600 to ₹900 for accounts with ₹5-10 Lakh holdings. BSDA saves an investor over 85% in recurring maintenance friction.
- Dynamic Recalibration: If market fluctuations reduce your portfolio value back below ₹4 Lakhs on the subsequent billing date, your broker must automatically restore your ₹0 AMC status.
Slab 3: Portfolio Value Exceeding ₹10,00,000 (Commercial Demat Transition)
Once your portfolio crosses the ₹10 Lakh milestone:
- Automatic Conversion: Your account automatically transitions from BSDA to a regular commercial Demat account.
- Standard Charges: You become subject to the standard AMC tariff structure of your broker (e.g., Zerodha's ₹300/year, or Upstox's zero-AMC lifetime options). Compare pricing in our Broker Charges Comparison.

If you are currently paying ₹300 to ₹900 annual AMC on a Demat account with less than ₹4 Lakhs in securities, follow this 4-step conversion protocol:
- Consolidate Secondary Accounts: Check whether you have old, unused Demat accounts with other brokers. Because SEBI permits only ONE Demat account per individual for BSDA eligibility, submit account closure requests for any inactive accounts.
- Verify Portfolio Valuation: Check your current consolidated holding statement (CAS) from CDSL or NSDL. Ensure your total portfolio value is under ₹4,00,000 for ₹0 AMC, or under ₹10,00,000 for the ₹100 slab.
- Submit BSDA Declaration Form:
• Online / App: Most leading discount brokers feature a self-service toggle under Profile → Account Details → Demat Plan → Opt for BSDA.
• Physical / Email: Download the standard BSDA Declaration Form from your broker's download center, sign it, and email it to customer support or dispatch it to their corporate office. - Confirmation & Refund of Prepaid AMC: Within 7 business days, your Depository Participant will verify your single-account status with CDSL/NSDL and update your tariff code to BSDA. Any unutilized prepaid quarterly AMC must be credited back according to depository rules.
