Quick answer. If your salary stopped crediting for 3 months and you now see “AMB CHGS” or “MAB PENL” debits, the bank converted your salary account to a regular savings account, usually without written notice. Demand the conversion notice in writing. If the bank cannot show it, ask for a full refund of every penalty deducted. If denied or ignored for 30 days, escalate to the RBI Banking Ombudsman under RB-IOS 2021 using ground “non-adherence to provisions of fair-practice code or any direction of RBI”.
If you are short on time, jump to the step-by-step refund workflow and copy the sample letter below.
Most Indian banks classify a “salary account” only while a recurring monthly credit tagged as SAL/SALARY arrives. When that tag stops for a defined window, usually 3 consecutive months, sometimes 2, the account is internally re-categorised as a regular savings account. The next billing cycle starts charging the Monthly Average Balance (MAB) penalty.
The problem is not that the rule exists. The problem is that it runs silently. Customers find out months later, often through a “Misc Debit” line worth ₹100 to ₹600, repeating month after month. Engineers between jobs, freelancers with irregular invoicing, retired employees, and women on maternity break are the most common victims.
The RBI's Master Direction on Customer Service tells banks to give “due notice” before any change to the terms of the account. “Due notice” in banking practice means a written communication, letter, email, or SMS, naming the change, its date, and the new charges. A passive footnote on a tariff PDF does not satisfy this. If the bank cannot produce the notice, the conversion is procedurally defective and the penalty is recoverable.
MAB stands for Monthly Average Balance, the average of the daily closing balance across the calendar month. So if you held ₹30,000 for 10 days and ₹0 for 20 days, your MAB is roughly ₹10,000.
Two terms cause confusion:
The penalty is computed as a slab, the more you fall short of the required figure, the higher the charge, capped per month. The cap varies by bank and by branch category (metro, urban, semi-urban, rural).
Numbers below are drawn from each bank's public Schedule of Charges as of May 2026. Always reconfirm on the bank's own tariff page, the figures revise without notice and vary by branch tier.
| Bank | Account type after conversion | Required MAB (metro) | Maximum monthly penalty |
|---|---|---|---|
| HDFC Bank | Regular Savings | ₹10,000 | ₹600 (6% of shortfall, capped at ₹600/month) |
| ICICI Bank | Regular Savings | ₹15,000 (₹50,000 for accounts opened on or after 1 Aug 2025) | ₹500 or 6% of shortfall, whichever is lower |
| Axis Bank | EasyAccess Savings | ₹10,000 | ₹600 |
| Kotak Mahindra | Edge Savings | ₹10,000 | ₹500 |
| SBI | Regular Savings (AMB) | ₹3,000 | ₹15 + GST (per slab) |
| PNB | Savings Fund | ₹2,000 | ₹250 |
| Bank of Baroda | Baroda Advantage Savings | ₹2,000 | ₹200 |
Private banks charge roughly 2x to 3x more than PSBs, which is why the silent conversion bites hardest at HDFC, ICICI, Axis and Kotak.
Banks update their Schedule of Charges between two and four times a year. Each revision sits on a single PDF on the bank's website, and the new figures usually kick in two weeks after publication. The customer is not separately notified, the act of putting it on the website is treated by the bank as “publication”.
That practice has been tested before the RBI Ombudsman more than once. The view that has held up is: publishing on the website is sufficient where the customer already had clear knowledge that a charge of that kind exists. It is not sufficient where a wholly new charge appears, or where the customer's product class changes, for example a salary account being recategorised as a regular savings account. In the second case, an individually addressed written notice is required.
This is why the silent conversion matters more than the MAB hike. A 10% revision in MAB charge applied to your existing regular savings account is hard to refund. The same charge applied because your salary account was reclassified without notice is fully refundable.
When you read the bank's defence on the ombudsman portal, watch for this conflation, banks often produce the website-revision date as if it were the conversion notice. Reject that explicitly in your rejoinder and ask the ombudsman to demand the individually addressed notice.
The RBI's stand is clear in three places:
A silent reclassification, with the customer first learning of it through a “Misc Debit” two months later, fails all three tests. That failure is what makes the refund argument winnable.
Open the last 12 months of your statement. Look for any of these narration codes, banks use different labels but the patterns are similar:
Tag every such line with date and amount in a small spreadsheet. Add 18% GST on top of the base charge, banks levy GST and the refund must include it.
The legal argument is short and clean:
The Consumer Protection Act 2019 §2(47) treats a “misleading representation … of the standard, quality, quantity or features of the service” as an unfair trade practice. A silent conversion is exactly that.
Download the statement for the period from the month after your last salary credit to today. Compute the total penalty + GST. Save the PDF.
Use the sample letter below. Send by email to the branch manager and the bank's official grievance email. Keep a delivery receipt.
The bank's published grievance redressal policy gives a 30-day reply window. Most refund requests are settled in this stage if the demand is precise and the amount is under ₹10,000.
If the branch refuses or ignores the request, write to the bank's Principal Nodal Officer. The PNO addresses are published on every bank's “Grievance Redressal” page. Mark a copy to the bank's Internal Ombudsman, every commercial bank with more than 10 branches must have one (RBI direction, 2018).
If 30 more days pass without a satisfactory reply, file the complaint on cms.rbi.org.in under the ground “non-adherence to provisions of fair practice code or any direction of RBI”. The full walkthrough is at RB-IOS 2021, complete file-online guide and the longer reference at Banking Ombudsman complaint guide.
The ombudsman gives the bank 15 days to respond on the portal. Read the reply carefully. If the bank claims notice was sent, ask the ombudsman to direct production of the specific dated notice. A vague “our system sent an SMS” is not evidence.
The ombudsman either passes an award (refund directed) or closes the complaint. If closed adversely, you have 30 days to file before the District Consumer Disputes Redressal Commission under the Consumer Protection Act 2019.

Subject: Refund of Minimum Average Balance penalty wrongfully levied
on Salary Account No. XXXXXXXX1234
Sir / Madam,
1. I am the holder of the above-mentioned account, opened on
[DD-MM-YYYY] as a Salary Account with zero balance terms in your
[branch name] branch. My then employer [Employer name] was the
sponsoring organisation.
2. The salary credit stopped on [DD-MM-YYYY] when I separated from
the employer. From [DD-MM-YYYY] onwards your bank has deducted
Minimum Average Balance penalty totalling ₹[amount] inclusive of
GST. A line-wise list is enclosed.
3. I have not received any written notice from the bank intimating
the conversion of my salary account into a regular savings account
or the levy of an MAB penalty. Under the RBI Master Direction on
Customer Service in Banks (rationalisation of charges), any such
change requires advance written intimation. In the absence of such
notice, the conversion is procedurally defective and every penalty
deducted thereunder is a wrongful debit.
4. I therefore request:
(a) full refund of ₹[amount] within 30 days;
(b) reversal of GST levied on those charges;
(c) immediate conversion of the account to a Basic Savings Bank
Deposit Account (BSBDA) or a no-frills variant of my choice;
(d) copy of the dated notice, if any, that the bank claims to
have served before the conversion.
In the absence of a satisfactory response within 30 days I will
approach the RBI Banking Ombudsman under RB-IOS 2021 and, if
required, the District Consumer Disputes Redressal Commission
under the Consumer Protection Act 2019.
Yours sincerely,

Enclosure: Statement extract showing penalty debits
Draft this letter quickly with the AI RTI Drafter, the same builder produces the RTI version below.
Public-sector banks (SBI, PNB, BoB, Canara, Union, Indian Bank) are “public authorities” under §2(h) of the RTI Act 2005 and have PIOs. Use the RTI route to extract:
Private banks (HDFC, ICICI, Axis, Kotak) are not directly covered by RTI but their disclosures to the RBI are. File an RTI to the RBI's PIO for the bank's compliance reports. The drafter at AI RTI Drafter handles both formats; if the PIO stalls, switch to First Appeal Builder after the 30-day silence.
For the full RTI workflow, see the citizen RTI playbook and the RTI vs alternatives pillar.
If the ombudsman closes adversely or the bank simply ignores the award:
Filing is online at edaakhil.nic.in. No advocate is mandatory for amounts up to ₹20 lakh.
Distinct from MAB, this is the safety net the RBI added in its 2024 circular on Inoperative Accounts and Unclaimed Deposits, accessible through the UDGAM portal:
If your account was charged MAB penalty during its inoperative phase, that too is recoverable as a separate ground in the same refund letter.
The cleanest fix once your salary credit stops is to ask the bank to convert the account to a Basic Savings Bank Deposit Account (BSBDA). RBI rules require every bank to offer BSBDA with:
A salary-account holder cannot be denied this conversion. The branch will sometimes push you toward a “Prime” or “Privilege” variant, politely refuse and insist on BSBDA. The request can be submitted on a one-page bank form; some banks accept it by email.
If you are likely to switch jobs frequently, the BSBDA route avoids future surprises entirely.
Scenario 1, Software engineer between jobs, Bengaluru.
[Name] left a product company in March 2026, took a 5-month break before joining another firm in August. HDFC silently converted his salary account in June; ₹590/month MAB penalty plus GST appeared as “Misc Debit” from June to October. Total loss ₹3,540. He sent the refund letter on 12 November, escalated to the PNO on 14 December, filed at cms.rbi.org.in on 16 January. Award passed on 9 February, full refund credited within 7 days.
Scenario 2, Freelance graphic designer, Pune.
[Name] used a Kotak salary account from her last in-house role. After turning freelance her invoices were paid to a different bank, so the Kotak account ran zero. She lost ₹2,400 over 6 months. Internal ombudsman refunded ₹2,100 in 22 days; she did not pursue the residual ₹300 as it covered one month before the bank's “grace period”. Lesson: a single grievance email reached the right desk.
Scenario 3, Retired DRDO scientist, Hyderabad.
[Name] retired in 2023. His SBI salary account stopped receiving pay in November and the pension routed to a different SBI account. AMB penalty of ₹15 + GST repeated for 26 months, small per month, ₹468 in total, plus ₹150 SMS pack hidden in the same code. SBI refunded everything within 11 days of a single branch letter, PSBs often settle without escalation if the demand is precise.
Banks routinely refund up to 12 months without resistance. For older debits, the limitation under the Consumer Protection Act 2019 is 2 years from the date of each debit. Older debits are not automatically barred, if you can show the silent-conversion pattern continued, a 5-year refund has been awarded by some district commissions. Keep the entire statement.
The RBI Master Direction asks for “due notice” of a change in terms. A standalone SMS, with no dated copy stored against your account ID, is rarely treated as sufficient by the ombudsman. Demand production of the exact SMS, the date, the gateway log, and the template ID approved by TRAI. If the bank cannot show this, the notice is unproven.
No. Savings-account closure does not appear on CIBIL. Only credit products do. Pay any outstanding penalty under protest, close the account, then pursue refund, or convert to BSBDA first and keep the account number alive while you fight.
No. RBI's BSBDA framework is a customer right. The bank can ask you to close any other savings account first (a customer can hold only one BSBDA), but cannot refuse the conversion itself. If pushed back, escalate the same day to the PNO with the RBI circular cited.
No, they are private banks. But their submissions to the RBI are. File an RTI to the RBI's PIO asking for the bank's grievance-redressal compliance and the inspection report covering customer-service practices. The bank's tariff publication obligation is independent and is challengeable directly under the Consumer Protection Act.
No. The “duty to know” rests on the bank that made the change, not the customer. As long as you raised the refund request within 2 years of the wrongful debit, your case holds. The longer-term theory of laches does not apply to wrongful debits.
That is a different fault, system error. Send a written request with the daily-balance computation. Banks resolve such system-error refunds within 7 working days because they cannot defend them. Keep the working in a separate annexure.
Yes. The ombudsman regularly awards simple interest at the savings rate (currently 2.7%-3% per annum). The consumer commission awards higher rates (9%-12%) where it finds unfair trade practice. State both in your prayer.
Yes to both. Banking charges attract 18% GST. When the principal charge is refunded, the bank must also reverse the GST against the same invoice. Insist on this, many branches refund only the principal and quietly retain the GST.
Bank policy varies. Some banks accept a credit every 90 days. Many require the SAL/SALARY tag specifically. Ask your branch in writing what the qualifying frequency is, that record is itself usable later. If you find the rule is hidden, file an RTI to the RBI for the relevant bank's customer-classification policy.
Two routes. (i) RBI's Daksh portal lets you submit a market-conduct concern that triggers off-site supervision. (ii) The CFPB-style “Banking Ombudsman” award becomes a public record on the RBI Annual Report and helps the next victim cite precedent. Both are worth pursuing in parallel.
