If you’re wondering why your bank took money from your account, the withdrawal almost always traces back to one of a handful of causes: a fee buried in your account agreement, a debt you owe the same bank, a court order or IRS levy, a recurring payment you authorized and forgot about, a reversed dispute credit, or a fraudulent charge. Which one applies determines what you can do and how fast you need to move.
Account Fees and Service Charges
Internal bank fees cause most small, unexplained balance drops. Monthly maintenance fees typically run between $5 and $25, depending on account type and whether you meet minimum balance or direct deposit requirements. A change in your paycheck schedule can suddenly trigger a fee that wasn’t hitting before, because the waiver condition stopped being met.
Overdraft fees have declined as major banks cut or eliminated them, but they haven’t vanished. As of 2025, the average overdraft fee had dropped to roughly $27, though some banks still charge as much as $35 per incident.1Consumer Financial Protection Bureau. Overdraft/NSF Revenue in 2023 Down More Than 50% Versus Pre-Pandemic Levels A single overdraft can cascade: if several transactions post the same day and your balance can’t cover them, multiple fees can hit in hours.
Out-of-network ATM withdrawals charge you twice: the ATM operator’s fee, and your own bank’s surcharge on top. Combined, those fees now average close to $5 per transaction. All of these charges sit in the fee schedule you received when you opened the account, though few people read it carefully until something goes wrong.
Right of Offset
If you owe money to the same bank where you keep your checking or savings account, the bank can pull funds from your deposit to cover that debt. This is called the right of offset, and it covers loans, lines of credit, and other obligations with that institution. The bank doesn’t need a court order because you agreed to the arrangement when you signed your account opening documents.2HelpWithMyBank.gov. May a Bank Use My Deposit Account to Pay a Loan to That Bank
Credit card debt is the major exception. Federal law prohibits a bank from offsetting your deposit account to pay a consumer credit card balance unless you previously authorized the bank in writing to make periodic deductions for that purpose. Even then, the bank cannot offset any amount you’re actively disputing.3Office of the Law Revision Counsel. 15 USC 1666h – Offset of Cardholders Indebtedness by Issuer of Credit Card
No broad federal law requires your bank to warn you before offsetting a deposit account. Whether you get advance notice depends on what your account agreement says. Some agreements promise a heads-up; many don’t. If you carry any loan with the bank that holds your deposits, read the offset clause now rather than after the money disappears. Keeping deposits at a different institution than your lender eliminates this risk entirely.
Garnishments and IRS Levies
Private creditors can reach into your bank account, but only after winning a lawsuit and obtaining a court judgment. Once the creditor has that judgment, they can serve your bank with a garnishment order requiring it to freeze the funds.4Consumer Financial Protection Bureau. Can a Debt Collector Take or Garnish My Wages or Benefits The bank usually charges you a processing fee for handling the paperwork, which adds to the sting.
The IRS plays by a different set of rules. It can levy your bank account without going to court, though it must send you written notice at least 30 days before the levy. That notice must explain your right to appeal, your options for setting up an installment agreement, and the procedures for getting property released.5Office of the Law Revision Counsel. 26 USC 6331 – Levy and Distraint Ignore the 30-day notice, and the IRS can proceed without further court involvement.
Protected Federal Benefits
Certain federal payments cannot be swept up in a garnishment. When your bank receives a garnishment order, it must review whether any of several federal benefits were deposited into your account during the previous two months. If so, the bank must protect an amount equal to those deposits and keep it accessible to you.6eCFR. 31 CFR Part 212 – Garnishment of Accounts Containing Federal Benefit Payments The protected payments include Social Security and SSI benefits, Veterans Affairs payments, Federal Railroad retirement, unemployment, and sickness benefits, and Civil Service and Federal Employee Retirement System benefits.
Child support enforcement orders are treated differently. A garnishment from a state child support agency can reach funds that would otherwise be protected under these rules.7Federal Register. Garnishment of Accounts Containing Federal Benefit Payments The bank performs the two-month lookback automatically, so you don’t need to file paperwork to access the protected amount. For any frozen funds above that amount, you’ll need to file an exemption claim with the court or contact the creditor to argue those funds should also be released.8Department of the Treasury/Bureau of the Fiscal Service. Guidelines for Garnishment of Accounts Containing Federal Benefit Payments
Recurring Debits You Authorized
Sometimes the “missing” money isn’t missing at all. It’s a recurring charge you forgot about or assumed had been canceled. Subscription services, gym memberships, insurance premiums, and loan payments tied to automatic ACH debits will keep pulling from your account until you formally stop them. Calling the merchant alone doesn’t always do the job.
Federal law gives you the right to stop any preauthorized recurring electronic transfer by notifying your bank at least three business days before the next scheduled debit. You can do this orally or in writing.9eCFR. 12 CFR 205.10 – Preauthorized Transfers If the bank still processes the payment after you gave proper notice, that debit is treated as an error, and you can demand a correction. Keep a record of when and how you told the bank to stop the payment. That’s where most disputes fall apart.
Reversed Provisional Credits
If you’ve ever disputed a charge, watched your balance jump back up, and then dropped again weeks later, you’ve experienced a provisional credit reversal. When you report a transaction error, your bank may temporarily restore the disputed amount while it investigates. If the investigation concludes the original charge was legitimate, the bank takes the temporary credit back.
The bank must finish its investigation and notify you of the results before reversing the provisional credit. If no error is found, it will send a written explanation and give you the underlying documents on request.10Consumer Financial Protection Bureau. Regulation E Section 1005.11 – Procedures for Resolving Errors A reversal can be an unpleasant surprise if you’ve already spent the credited funds, so treat a provisional credit as money you might have to give back until you receive written confirmation the dispute resolved in your favor.
Unauthorized Transactions and Fraud
Fraudulent charges and processing errors create their own category of unexpected balance changes. A merchant might double-charge you, a stolen debit card number could fund someone else’s purchases, or the bank’s own system could misapply a transaction. How quickly you report it controls how much of the loss you bear.
Federal rules cap your liability for unauthorized electronic transfers based on how fast you act:11eCFR. 12 CFR 205.6 – Liability of Consumer for Unauthorized Transfers
- Report within 2 business days of learning your card was lost or stolen, and your maximum liability is $50.
- Wait longer than 2 business days but report before your next statement arrives, and your maximum liability rises to $500.
- Wait more than 60 days after your statement is sent, and you could be on the hook for the full amount of unauthorized transfers that occur after that 60-day window, with no cap.
That third tier catches people. If a fraudulent charge sits on your statement for two months and you never report it, the bank has no obligation to cover subsequent unauthorized transfers it can show would have been prevented by timely notice. Check your statements every month, because the clock is running on your legal protections from the moment the statement is sent.
Hotel and gas station authorization holds are a separate issue. They can tie up $50 to $150 of your available balance for several days before the final charge posts. These aren’t errors and aren’t unauthorized. They clear on their own, but they can trigger overdrafts if your balance is tight.
Joint Accounts and a Co-Owner’s Debts
Sharing a bank account exposes your money to the other person’s financial problems. If your co-owner falls behind on a loan with the same bank, the bank’s right of offset language may let it pull funds from the joint account to cover that debt, even if every dollar came from you. The bank typically doesn’t distinguish whose paycheck funded which deposit.
Garnishment works the same way. A creditor with a judgment against your co-owner can serve a garnishment order on the joint account. As a non-debtor co-owner, you have legal options to protect your share, but they require fast action. You’ll generally need to request a hearing and prove the funds are traceable to your contributions, not the debtor’s. Money from exempt sources like Social Security, disability payments, or retirement income keeps its protected status after being deposited into a joint account, provided you can document the source.
If you need shared access for household expenses, fund a joint account with only what’s needed for immediate bills and keep the rest in an individual account.
Dormant Account Transfers
If you stop using a bank account and don’t contact the bank for an extended period, the bank will eventually be required to turn the balance over to the state as unclaimed property. The dormancy period is typically three to five years, depending on the state.12HelpWithMyBank.gov. When Is a Deposit Account Considered Abandoned or Unclaimed Before that happens, the bank is usually required to try reaching you at your last known address. If you don’t respond, the money goes to the state.
The money isn’t gone forever. Every state maintains an unclaimed property database where you can search for and reclaim the funds. In the meantime, your balance drops to zero with no warning beyond a letter the bank mailed to an address you may no longer use. If you have old accounts you’ve forgotten about, make at least one transaction or contact the bank periodically to keep them active.
How to Push Back on a Withdrawal
Start by calling your bank and asking for a clear explanation of the charge, including the legal authority or account agreement provision it relied on. Get the answer in writing when you can. From there, the next move depends on the cause:
- Right of offset you believe was improper: file a formal written complaint with the bank’s customer service department, provide copies of relevant records, and if the bank doesn’t resolve it, file a complaint with the Consumer Financial Protection Bureau.13USAGov. Bank, Credit, and Securities Complaints
- Garnishment that caught protected funds: you don’t need to do anything to access the automatically protected amount from federal benefit deposits. For frozen funds above that amount, file a garnishment exemption form with the court that issued the order and explain the source of the funds.8Department of the Treasury/Bureau of the Fiscal Service. Guidelines for Garnishment of Accounts Containing Federal Benefit Payments
- IRS levy: the IRS must release a levy if you’ve paid the balance, entered an installment agreement, or if the levy creates an economic hardship that prevents you from covering basic living expenses. You can also appeal a denied release request.14Internal Revenue Service. How Do I Get a Levy Released
- Unauthorized transaction: report it to your bank immediately. The sooner you act, the lower your potential liability. Your bank must investigate under Regulation E and provisionally credit your account within 10 business days if the investigation isn’t finished.10Consumer Financial Protection Bureau. Regulation E Section 1005.11 – Procedures for Resolving Errors
- Unwanted recurring debit: notify your bank at least three business days before the next scheduled transfer, put it in writing, and keep a copy.9eCFR. 12 CFR 205.10 – Preauthorized Transfers
Document everything: dates you called, names of representatives, reference numbers, and copies of letters. Banks handle millions of accounts, and the disputes that get resolved fastest are the ones with a clear paper trail behind them.
