Banks generally cannot charge you an overdraft fee on a debit card or ATM transaction unless you opted in to that coverage. The catch is that checks and recurring electronic payments can still carry fees without an opt-in, and overdraft fees often run $30 or more per transaction. Checking your status takes one call or a look at your account settings.

How overdraft fees work
An overdraft happens when a payment is bigger than your balance and the bank covers the shortfall anyway. The bank then charges a fee. According to the Consumer Financial Protection Bureau, those overdraft fees often run $30 or more per transaction, several can hit in a single day (although some institutions set daily maximums), and many institutions add a further charge if you do not repay the shortfall within a few days.
Without overdraft coverage, a debit card purchase that exceeds your balance is generally declined, and no overdraft fee applies. Many people never realize they said yes to coverage when they opened the account.
What the opt-in rule covers, and what it doesn’t
The federal opt-in rule is narrower than most people assume. Institutions cannot charge for overdrafts on ATM transactions and one-time debit card purchases unless you chose to opt in. The CFPB also says banks can still charge overdraft fees on checks and recurring electronic payments without that opt-in. Some banks let you turn off coverage for those too, but a declined payment can bring a non-sufficient funds fee, often about the same amount, and a merchant may charge its own returned-item fee.
That is why “no overdraft coverage” does not always mean “no fee.” If an autopay for rent or a utility is likely to bounce, a decline can cost as much as an overdraft.
Can the government cap the fee?
Not at the moment. A CFPB rule would have limited overdraft fees at banks with more than $10 billion in assets, by setting a $5 benchmark unless the bank could justify its costs or treated coverage as credit. According to a law-firm summary, the president signed a Congressional Review Act resolution nullifying the rule in May 2025, before its Oct. 1, 2025 effective date, and the bureau is barred from issuing a substantially similar rule. Large banks are therefore not subject to a federal fee cap, so state action and your own settings matter more.
Four ways to cut your overdraft risk
The CFPB lists three main options. You can opt out of debit and ATM overdraft coverage so purchases are declined instead of overdrawn. You can link checking to a savings account, which pulls money from savings to cover a shortfall for a transfer fee that the bureau says is “less than the fee for an overdraft.” Or you can ask about a line of credit or credit card that backs the account, though that may bring a fee when it is used and interest on what you borrow.
A fourth, practical step is to choose an account built to avoid fees. Our comparisons of the best checking accounts, best online banks and Chime, Varo and Current include overdraft terms. Ask any bank the same questions before you open an account: what is the overdraft fee, is there a daily maximum, is there a transfer fee for linked savings, and does opting out apply to checks and bill pay?
If you were charged a fee you didn’t expect
Start by checking whether you opted in. If you do not believe you authorized debit overdraft protection and the bank charged a debit overdraft fee, the CFPB says you may file a complaint at consumerfinance.gov/complaint or by calling (855) 411-2372. The bureau forwards complaints to the company, and you should generally get a response within 15 days. Before that, ask the bank to reverse the fee in writing and keep the date and the name of who you spoke with.
Editor’s take
Overdraft coverage is a loan with a price tag that is easy to underestimate. For most people a linked savings account with a small buffer is the cheapest backstop, and opting out of debit overdraft coverage is the cleanest fix when the account has no cushion. The overlooked risk is the autopay that bounces, so move those due dates to just after payday.
