A federal rule requires a bank to get a customer’s explicit opt-in before it can charge an overdraft fee on a debit-card purchase or ATM withdrawal, and any customer who declines that opt-in, or revokes one already given, stops that specific fee entirely. The charge itself is not small. The Consumer Financial Protection Bureau’s own review of the country’s largest banks and credit unions found the median overdraft fee ran about $35 per transaction. Declining the coverage means a card is generally declined at checkout when funds run short instead — no purchase, no fee — a tradeoff that is one of the few overdraft disputes a customer can settle alone, without negotiating or filing a complaint.
A Bank Cannot Charge the Fee Without an Opt-In
The mechanism is written directly into Regulation E, the rule implementing the Electronic Fund Transfer Act. Under 12 CFR 1005.17(b), a financial institution shall not assess a fee or charge on a consumer’s account for paying an ATM or one-time debit card transaction pursuant to the institution’s overdraft service unless it first gives the customer a segregated written notice, a genuine opportunity to consent, and then obtains that consent affirmatively — a signature, a checked box, or a recorded verbal yes. Silence does not count. If a customer never responds to the opt-in offer, the bank has to treat the account as opted out by default.
That consent is also never locked in. The CFPB confirms a customer can change the overdraft decision at any time by telling the financial institution, and the regulation requires the bank to put a revocation into effect as soon as reasonably practicable. Fees already charged before the change takes effect are not refunded automatically, but nothing assessed afterward on an ATM or one-time debit transaction can carry a coverage fee — the account simply reverts to the default rule under which the transaction gets declined instead of paid.
The rule has been in force long enough that most current account holders already made this decision once, often without realizing it. Existing accounts had to have an opt-in on file by August 15, 2010, or banks were barred from charging the fee going forward, and every account opened since must be asked the question at account opening, typically through a signature line or a checkbox presented apart from the rest of the paperwork. A customer who checked that box a decade ago, or let a teller check it during a routine account opening, is still opted in today unless they specifically revoke it.

What the $35 Fee Buys — and What Happens Without It
Without an opt-in on file, a bank’s own systems are supposed to decline a debit-card purchase or ATM withdrawal the moment it would push the account negative. The transaction simply does not go through — an inconvenience at the register or the machine, not a bill that shows up on the next statement. That is the entire tradeoff: coverage means an overdrawn purchase is quietly paid and charged for later, while opting out means the purchase is refused up front and nothing is charged at all.
The fee that opting out avoids is not trivial. In its December 2023 overdraft and non-sufficient-funds report, the CFPB found the median overdraft fee among the 119 banks and credit unions with more than $10 billion in assets was $35 per transaction, based on account data collected in December 2022 and August 2023. Because a bank can charge a separate fee for each transaction that overdraws the account on a given day, several small purchases hitting at the wrong moment can multiply that $35 well before the balance is brought current again.
The bureau’s account-level data makes the annual gap concrete rather than theoretical: customers who had opted into ATM and debit-card overdraft coverage paid close to $260 a year on average in combined overdraft and non-sufficient-fund fees, compared with a little over $35 a year for accounts that had not opted in. That gap is not explained by opted-in customers overdrawing more often — it is largely the fee itself compounding across a year of ordinary timing gaps between paychecks and bills.
The Decision Sits With the Account Holder, Not the Bank
A bank retains some discretion the opt-in rule does not touch. Regulation E allows an institution to pay an ATM or one-time debit overdraft even without a customer’s consent — it just forfeits the right to charge for doing so if it makes that choice. In practice, most banks decline rather than absorb the cost, which is why an opted-out customer typically sees a declined transaction rather than a surprise payment covered on their behalf.
The same regulation also bars a bank from punishing the choice to opt out. An institution has to offer a customer who declines the same account terms, interest rates, minimum-balance rules, and card features it offers to a customer who opts in — the only permitted difference is whether ATM and one-time debit overdrafts get paid and charged for. A bank cannot hand an opted-out customer a stripped-down account or a PIN-only card as a workaround.
What keeps the $35 fee flowing for millions of accounts anyway is rarely the legal fine print — it is that most customers never revisit a box they checked, or had checked for them, years earlier. The rule gives every account holder a standing, no-questions-asked way to shut the fee off going forward; the remaining gap is simply how few people know that decision was ever theirs to make again.
