A “Cash On Us” charge on a bank statement is the bank’s label for a cash transaction it handled entirely in-house, without sending anything through an outside clearing network. In almost every case, it’s a teller-window cash withdrawal from your account, or a check you wrote that someone cashed at a branch of your own bank. The line looks strange because there’s no merchant name and no ATM code, but the activity behind it is routine.
What “On Us” Means
In banking, an “on-us” item is any check, withdrawal, or payment where the same institution sits on both sides of the transaction. If you write a check on your account and the payee walks into a branch of that same bank to cash it, the bank can verify your balance and debit your account on the spot. It doesn’t have to send the check through the Federal Reserve or a private clearinghouse. That internal shortcut is what the “on us” wording on your statement is describing.
Two situations create on-us items. Either the person receiving your money uses the same bank you do, or a non-customer brings your check directly to your bank’s branch to cash it. In both cases the bank processes the transaction against its own ledger and tags it with a descriptor like “Cash On Us,” “OTC On-Us,” or a similar abbreviation.
The Two Everyday Reasons This Line Appears
The most common trigger is a teller withdrawal. When you walk into a branch and take cash out at the counter, the transaction is processed internally rather than through an ATM network, so it doesn’t carry an ATM identifier. It shows up as an on-us item instead. If the date and amount line up with a recent branch visit, that’s your answer.
Teller withdrawals also tend to be larger than ATM withdrawals because they bypass the daily ATM cap. Most ATM daily limits sit between $300 and $1,500, depending on the bank and account. If you needed more cash than the machine would give you and went inside, expect to see the on-us label on the statement.
The second common trigger is someone cashing a check you wrote. When the payee brings your check to your bank rather than depositing it at their own, the teller debits your account immediately. Your statement records the amount leaving, but with the on-us label instead of the payee’s name or the check number. That mismatch is what confuses most people who see this line for the first time.
Check It Against Your Own Activity First
Before treating this as fraud, spend a few minutes ruling out the obvious. Match the date and amount to any recent branch visits, teller receipts, or checks you’ve written. Pull up your check register or your online image archive and see whether a check you wrote around that date was cashed for that amount.
If anyone else is authorized on the account, ask whether they made a branch withdrawal or wrote a check that has since been cashed. A large share of “unauthorized” on-us charges turn out to be a spouse’s teller visit or a check the account holder wrote weeks earlier and forgot about.
If nothing matches, write down the transaction date, the exact dollar amount, and any branch location shown on the statement. Pull any teller receipts or digital confirmations you can find. Having those details ready before you call the bank keeps the conversation short and gives the fraud team something concrete to work with.
The 60-Day Deadline If the Charge Is Really Unauthorized
If the charge doesn’t match anything you or anyone else on the account did, timing matters more than almost anything else. Under Regulation E, you have 60 days from the date your bank sends you the periodic statement showing the transaction to report an unauthorized electronic fund transfer. If you miss that window, you can be held liable for every unauthorized transaction that happens after the 60 days run out and before you finally notify the bank.1eCFR. 12 CFR 1005.6 – Liability of Consumer for Unauthorized Transfers
Your exposure depends on how quickly you speak up:
- Report within 2 business days of learning about the loss or theft, and your maximum liability is $50, or the amount taken before you notified the bank, whichever is less.
- Report after 2 business days but within 60 days of the statement, and your liability can climb to $500, covering unauthorized transfers between day two and the date you notify the bank.
- Report after 60 days, and there is no statutory cap on unauthorized transfers that occur after the window closes.1eCFR. 12 CFR 1005.6 – Liability of Consumer for Unauthorized Transfers
The practical lesson is to open statements when they arrive. People who let months of statements stack up unopened are the ones who lose the most under this rule.
How the Dispute Works
Once you’re confident the charge isn’t yours, contact your bank’s fraud department by phone, through online banking, or at a branch. Oral notice is enough to start the process, but the bank can require you to follow up with a written statement within 10 business days. If it asks for that written confirmation and you don’t send it, the bank can close the investigation without giving you the extended timeline described below.2Consumer Financial Protection Bureau. 12 CFR 1005.11 – Procedures for Resolving Errors
After the bank receives your error notice, it has 10 business days to investigate and decide whether an error occurred. If it finishes within that window, it must tell you the result within three business days and correct any error within one business day of confirming it. If it can’t finish in 10 business days, it can take up to 45 days total, but only if it provisionally credits your account for the disputed amount within the first 10 business days. You get full use of that provisional credit while the investigation continues.2Consumer Financial Protection Bureau. 12 CFR 1005.11 – Procedures for Resolving Errors
When the investigation ends, the bank must send a written explanation of its findings. If it decides no error occurred, that notice must tell you how to request copies of the documents it relied on. If it had provisionally credited your account and then concludes the charge was legitimate, it can reverse the credit, but it has to give you notice before pulling the money back.2Consumer Financial Protection Bureau. 12 CFR 1005.11 – Procedures for Resolving Errors
One boundary worth flagging: if the on-us item is a check you actually wrote and later regret, that’s not an unauthorized transfer under these rules. The dispute process above is for transactions you or an authorized user did not make. A check you signed is your obligation, even if the payee cashed it earlier or later than you expected.
