The rules for a cash deposit come from three places: federal availability rules that say when you can spend the money, Bank Secrecy Act rules that require your bank to report cash transactions above $10,000, and anti-structuring law that makes it a crime to break a deposit into smaller pieces to avoid that report. Hand cash to a teller and the full amount has to be available by the next business day. Deposit more than $10,000 and the bank files a routine report with the Treasury Department. Try to dodge that report by splitting the deposit, and you have committed a federal felony even if every dollar is legitimate.
When the Money Becomes Available
Regulation CC sets maximum hold times, and cash gets the fastest treatment of any deposit. The timeline depends on how you deposit it.
- Cash handed to a teller in person: the full amount must be available by the next business day after the day of deposit.
- Cash deposited at your own bank’s ATM: available no later than the second business day after deposit.
- Cash deposited at an ATM not owned by your bank: available no later than the fifth business day.
The in-person rule is the one worth remembering. When cash passes directly to a bank employee, federal law requires next-business-day availability for the entire amount, with no partial hold.1eCFR. 12 CFR 229.10 – Next-Day Availability ATM deposits sit longer because the bank can’t verify what’s inside the machine until it is serviced. Non-proprietary ATMs sit longest because the depositary bank treats those deposits as if they were checks until the composition is confirmed.2eCFR. 12 CFR 229.12 – Availability Schedule
One boundary worth flagging: references you may see to a $275 minimum-availability figure or a $6,725 large-deposit threshold apply to check deposits, not cash.3Consumer Financial Protection Bureau. Availability of Funds and Collection of Checks (Regulation CC) Threshold Adjustments Banks can extend holds on large check deposits up to seven business days under exception rules, but those exceptions do not reach a teller-window cash deposit because there is no risk the cash will bounce.4Office of the Comptroller of the Currency. Funds Availability Exceptions If you need fast access to deposited cash, the teller window is always the safest route.
The $10,000 Reporting Rule
Under the Bank Secrecy Act, any cash transaction over $10,000 triggers a mandatory Currency Transaction Report (CTR), which the bank files with the Financial Crimes Enforcement Network (FinCEN), a bureau of the Treasury Department.5FinCEN. The Bank Secrecy Act The rule covers deposits, withdrawals, currency exchanges, and other transfers of physical cash.
The threshold is not per visit. It applies to your combined cash transactions at the same bank on the same business day. Two $5,500 deposits on the same day at the same institution add to $11,000, and the bank must file a CTR.6FFIEC BSA/AML InfoBase. Assessing Compliance with BSA Regulatory Requirements – Currency Transaction Reporting You do not fill out anything extra. The bank handles the filing, which must happen within 15 days of the transaction, and the report is retained for five years.7eCFR. 31 CFR 1010.306 – Filing of Reports
A CTR is not an accusation. Depositing $15,000 in legitimately earned cash is perfectly legal; the bank is simply required to document it. The report goes into a federal database that law enforcement can query during investigations. Expect the teller to ask where the cash came from as part of routine compliance. A straightforward answer is all that’s needed.
Why You Should Never Split a Large Deposit
The worst move with a large amount of cash is to break it into pieces to stay under $10,000. That is called structuring, and it is a federal felony regardless of whether the underlying money is clean. Someone who splits a $12,000 deposit into two $6,000 deposits on consecutive days to avoid a CTR has committed a crime even if every dollar was lawfully earned.8Office of the Law Revision Counsel. 31 USC 5324 – Structuring Transactions to Evade Reporting Requirement Prohibited
The penalty is a fine, imprisonment for up to five years, or both. If the structuring is connected to another federal crime or involves more than $100,000 in a 12-month period, the maximum rises to 10 years and the fine doubles.8Office of the Law Revision Counsel. 31 USC 5324 – Structuring Transactions to Evade Reporting Requirement Prohibited The government can also seize the structured funds through civil forfeiture, and fighting a forfeiture case is expensive even when the underlying cash was legitimate.
The practical rule is simple. If you have a large amount of cash to deposit, deposit it. The CTR is a routine administrative filing that creates no legal exposure for you. Structuring the deposit to avoid that filing creates enormous legal exposure.
Suspicious Activity Reports You Will Never See
Separate from the CTR, banks must file a Suspicious Activity Report (SAR) with FinCEN whenever a transaction of $5,000 or more looks like it could involve illegal activity or an attempt to evade reporting requirements.9FinCEN. FinCEN Suspicious Activity Report Electronic Filing Instructions Structuring patterns are a common trigger, but any transaction the bank finds suspicious can prompt one.
Unlike a CTR, a SAR is invisible to you. Federal law prohibits the bank from telling you one has been filed, and the bank and its employees are shielded from liability for the filing.10FFIEC BSA/AML InfoBase. Assessing Compliance with BSA Regulatory Requirements – Suspicious Activity Reporting
Deposit Limits and Source-of-Funds Questions
Teller deposits do not have a hard upper limit, but ATM deposits often do. Caps vary by bank and account type, with many institutions limiting ATM deposits to between $5,000 and $10,000 per day. If you are depositing more than your ATM allows, you’ll need the teller window.
For any sizable deposit, the teller may ask about the source of the funds. Banks are required under federal anti-money-laundering rules to understand where large amounts of cash come from, and the question is part of their compliance program. A plain answer (“I sold a car,” “this is from my business”) is enough. Refusing to explain the source can result in the bank declining the deposit, and in repeated or suspicious cases, closing the account.
Business accounts carry an additional cost layer. Many banks charge a cash-handling fee once monthly deposits exceed a threshold. Bank of America’s small-business checking account, for example, allows $5,000 in free cash deposits per statement cycle and then charges $0.30 per $100. If your business handles significant cash, these fees add up and are worth comparing before opening an account.
If the Amount That Posts Is Wrong
ATMs miscount. Tellers mistype. Regulation E gives you 60 days from the date your bank sends the statement reflecting the error to notify the institution.11Consumer Financial Protection Bureau. Regulation 1005.11 – Procedures for Resolving Errors You can report by phone or in writing. Include your name, account number, the date of the deposit, the amount you deposited, and the amount that actually posted.
Once the bank receives your notice, it has 10 business days to investigate and resolve the dispute. It can extend the investigation to 45 days, but only if it provisionally credits your account for the disputed amount within those first 10 business days, so you are not left short while the bank sorts it out.11Consumer Financial Protection Bureau. Regulation 1005.11 – Procedures for Resolving Errors The bank must report its findings to you within three business days of completing the investigation.
Keep your deposit receipts. A time-stamped receipt showing a different figure than what posted is the fastest way to get a discrepancy resolved. Without one, the investigation still has to happen, but it takes longer and leans entirely on the bank’s internal records.
