A debit memo on your bank statement means the bank itself subtracted money from your account, rather than the withdrawal coming from a card swipe, a check you wrote, or an ATM visit. The entry is the bank’s own record of pulling funds out, and it usually covers one of three things: a fee the bank charged you, a correction to a previous transaction, or a recurring electronic payment you authorized in advance. Amounts range from a few dollars for routine service charges to a few hundred for corrective entries, and each one should tie back to something specific.
What a Debit Memo Actually Is
Every dollar you deposit is a liability on the bank’s books, because the bank owes that money back to you. A debit memo reduces that liability by removing funds from your account, and the entry documents the reason. It differs from a regular purchase or ATM withdrawal in one key way: the bank initiates it, not you or a merchant standing at a register.
You’ll typically see debit memos fall into three buckets. Fees the bank charges you for services. Corrections that reverse a mistaken credit or a bounced deposit. And recurring electronic transfers that the bank’s system labels with a generic tag rather than the merchant’s name. Matching a debit memo to one of these three usually explains what happened.
Common Reasons a Debit Memo Appears
Bank Fees
The most common debit memos are service and maintenance charges. Monthly maintenance fees at major banks typically fall between $5 and $25, with some accounts running as high as $35 depending on the tier.1Experian.

Wire transfer fees show up the same way. Domestic outgoing wires at most major banks cost $25 to $30, and some institutions charge up to $40 depending on whether you send the wire online or in a branch.2Citizens Bank. What Is a Wire Transfer and How Does It Work? – Section: How much does a wire transfer cost? Overdraft fees vary widely: some banks have eliminated them, while others still charge $10 to $36 per occurrence, with daily caps of one to five fees.3NerdWallet. Overdraft Fees 2026: Compare What Banks Charge Stop payment orders generally run about $35.
If an account sits unused, some banks add inactivity or dormancy fees through debit memos, often after 12 months of no customer activity. After three to five years of continued inactivity (the exact period depends on state law), the bank must turn the remaining balance over to the state as unclaimed property.4OCC.

Corrections and Returned Items
Sometimes a debit memo isn’t a fee at all. It’s the bank undoing something. The most common scenario: you deposit a check, the bank credits your account, and the check bounces because the payer’s account is short. The bank reverses the credit with a debit memo for the full check amount and may add a returned-deposit fee. Bank of America, for example, charges $12 for a domestic returned item and $15 for a foreign one.5Bank of America.

Duplicate deposits get the same treatment. If an automated system credits the same deposit twice, the bank issues a debit memo to pull back the extra amount. These aren’t penalties; they’re bookkeeping corrections, and the memo exists so both sides can trace what happened.
Scheduled ACH Payments
Recurring bills paid through the ACH network often show up as debit memos, especially on older banking platforms. A gym membership, utility bill, or insurance premium gets pulled by the merchant on a schedule you set up earlier. Modern apps usually display the merchant name, but legacy systems at smaller banks may label these with generic tags like “ACH DEBIT” or “ELECTRONIC WITHDRAWAL” that don’t obviously identify who took the money.
You can revoke ACH authorization at any time. To stop a company from continuing to pull payments, contact your bank in writing and notify the merchant separately. After you’ve done both, any further withdrawals by that company are treated as errors, and you can request a refund from your bank.6Consumer Financial Protection Bureau.

Codes and Abbreviations You Might See
Banks don’t always spell out “debit memo” in full. Common shorthand includes “DM” for debit memo, “SC” for service charge, “RTN” for a returned item, and “COR” for a corrective entry. Older core banking systems at smaller community banks are especially prone to cryptic codes. If a label doesn’t match anything you recognize, the bank’s customer service line can translate it and tell you which transaction it refers to.
Debit Memo vs. Credit Memo
A credit memo is the opposite of a debit memo. Where a debit memo reduces your balance, a credit memo increases it. Credit memos post when the bank adds money for reasons other than a standard deposit: interest earned, reimbursement of a fee, or a refund of an unauthorized charge. When a debit memo and a credit memo for the same amount appear on the same day, that usually means the bank fixed an error in real time. When the two don’t match, the difference is worth asking about.
How to Dispute a Debit Memo You Don’t Recognize
If a debit memo doesn’t match any fee, adjustment, or recurring payment you can identify, gather three pieces of information before contacting the bank: the date the entry posted, the exact dollar amount, and any code or description attached. Many issues, like a mislabeled ACH payment, get sorted out in a single call.
For electronic fund transfers, Regulation E gives you 60 days from the date the bank sends or makes available the statement showing the error to report it.7eCFR. 12 CFR Part 1005 – Electronic Fund Transfers (Regulation E) Missing that window doesn’t erase every option, but it can limit the bank’s obligation to investigate and could leave you on the hook for losses that continued afterward.
Once you file a notice of error, the bank has 10 business days to investigate and reach a conclusion. It can extend the investigation to 45 days, but only if it provisionally credits your account within those first 10 business days so you aren’t out the money while it works.8Consumer Financial Protection Bureau. 12 CFR 1005.11 – Procedures for Resolving Errors New accounts (within 30 days of the first deposit) get longer windows: 20 business days for the initial investigation and up to 90 days total.
If a bank ignores those deadlines or refuses provisional credit when it’s required, the Electronic Fund Transfer Act lets you sue for actual damages plus statutory damages of $100 to $1,000 per individual action, along with attorney’s fees.9Office of the Law Revision Counsel. 15 USC Chapter 41, Subchapter VI – Electronic Fund Transfers
How to Avoid Debit Memos Going Forward
Most fee-related debit memos are avoidable once you know what triggers them. Monthly maintenance fees can often be waived by meeting one requirement. Bank of America, for instance, waives its $12 monthly fee if you keep a $1,500 daily minimum balance or receive at least one direct deposit of $250 or more per statement cycle.10Bank of America. Advantage Plus Banking Clarity Statement – Overview of Key Policies and Fees Most major banks offer similar waiver paths tied to minimum balances, direct deposits, or loyalty programs.
Overdraft fees are worth a separate look. Federal rules require your bank to get your explicit consent before charging overdraft fees on debit card and ATM transactions. If you never opted in, the bank must decline those transactions rather than approve them and charge you.11Consumer Financial Protection Bureau. 12 CFR 1005.17 – Requirements for Overdraft Services Many people opt in at account opening without realizing it. You can check your account settings and revoke that consent whenever you like. For checks and ACH payments the rule works differently: banks can pay those into overdraft and charge a fee without your opt-in, so keeping a small buffer in the account is the practical protection.
For recurring ACH debits you no longer want, the two-step revocation (in writing to the bank, and separately to the merchant) shuts them off. For dormant accounts, a single small transaction resets the inactivity clock and keeps a dormancy fee off the next statement.
