Depositing more than $10,000 in cash is legal. No federal law caps how much physical currency you can put into your own account. What the law requires is paperwork on the bank’s end: when a cash transaction crosses $10,000 in a single business day, the bank files a Currency Transaction Report with the Financial Crimes Enforcement Network (FinCEN). You bring the cash and your ID; the bank handles the rest.
What the Bank Files
Under the Bank Secrecy Act, every bank, credit union, and similar financial institution must file a Currency Transaction Report (CTR) with FinCEN whenever a customer’s cash transaction exceeds $10,000 in one business day. The rule covers deposits, withdrawals, currency exchanges, and other transfers of physical currency.1eCFR. 31 CFR 1010.311 – Filing Obligations for Reports of Transactions in Currency The bank files electronically through the BSA E-Filing system within 15 days.2eCFR. 31 CFR Part 1010 – General Provisions
You will not see the form, sign it, or pay a fee for it. You get your usual deposit receipt, and the money posts to your account like any other deposit. A CTR is not an accusation. It’s a routine filing every bank makes on every qualifying transaction, all day, every day.
What You’ll Need at the Counter
The teller has to collect a few pieces of information to complete the CTR. Have these ready:
- A government-issued photo ID such as a driver’s license, passport, state ID card, or military ID. The teller records the document type, issuing authority, and ID number.
- Your full legal name and permanent home address, including ZIP code.
- Your Social Security Number or Taxpayer Identification Number (an Employer Identification Number for a business).
- Your occupation, described briefly — teacher, contractor, retired, and so on.
These fields come directly from the CTR form.3Internal Revenue Service. FinCEN Form 104 – Currency Transaction Report If you’re depositing on behalf of another person or a business, the teller collects identifying information for both you and whoever you represent.
Tellers often also ask where the cash came from — a vehicle sale, savings, an inheritance, a gift. The CTR form itself doesn’t have a source-of-funds field, but banks ask as part of their internal compliance procedures. Answer honestly and the transaction moves along.
Don’t Split the Deposit
The biggest mistake people make with large cash deposits is breaking them into smaller amounts to stay under $10,000. That’s called structuring, and it’s a federal crime under 31 U.S.C. § 5324, even when every dollar is clean.4Office of the Law Revision Counsel. 31 USC 5324 – Structuring Transactions to Evade Reporting Requirement Prohibited Depositing $4,500 on Monday, $4,500 on Wednesday, and $4,500 on Friday instead of one $13,500 deposit is exactly the pattern investigators look for.
Banks run automated software that flags these patterns. When something looks like structuring, the bank files a Suspicious Activity Report with FinCEN, and federal law bars any bank employee or contractor from telling you it happened.5Office of the Law Revision Counsel. 31 USC 5318 – Compliance, Exemptions, and Summons Authority You get no warning and no chance to explain before the report reaches investigators.
A standard structuring violation carries up to five years in prison and fines. If the conduct is tied to other illegal activity or involves more than $100,000 over a 12-month period, the maximum sentence rises to 10 years and the fines double.4Office of the Law Revision Counsel. 31 USC 5324 – Structuring Transactions to Evade Reporting Requirement Prohibited
Structuring can also cost you the money itself. Under 31 U.S.C. § 5317, property involved in a structuring violation can be seized through civil forfeiture, where the government’s burden of proof is lower than in a criminal case. A 2015 policy change limits IRS seizures to cases where the money came from an illegal source or the structuring was meant to conceal another crime, but recovering seized funds is still slow and expensive.6Office of the Law Revision Counsel. 31 USC 5317 – Search and Forfeiture of Monetary Instruments Make one deposit and let the bank file the CTR.
Same-Day Deposits Get Added Together
You cannot beat the threshold by making several smaller deposits in one day. Federal rules require banks to aggregate all cash transactions by the same person during a single business day, and different branches share the same system. Deposit $6,000 at one branch in the morning and $5,000 at another that afternoon and the combined $11,000 triggers a CTR.7Financial Crimes Enforcement Network. Frequently Asked Questions Regarding the FinCEN Currency Transaction Report (CTR) The rule also mixes transaction types, so a deposit and a withdrawal on the same day can combine.
When You Can Actually Spend It
Under Regulation CC, cash handed to a bank employee is generally available by the next business day. For larger deposits, the bank must make the first $6,725 available on its normal schedule but can place a hold on the rest for a reasonable period.8Federal Reserve. A Guide to Regulation CC Compliance Deposit $15,000 in cash and expect most of it available the next day, with a possible short hold on the balance.
Cutoff times matter. Deposits made after the branch cutoff — which can be as early as 2:00 p.m. — are treated as next-business-day deposits for availability purposes.9Consumer Financial Protection Bureau.

A Few Related Rules to Know
Buying money orders, cashier’s checks, bank drafts, or traveler’s checks with cash sits under a separate, lower recordkeeping threshold. Banks must log identifying information for any cash purchase of these instruments totaling $3,000 or more, and same-day purchases are added together.10eCFR. 31 CFR 1010.415 – Purchases of Bank Checks and Drafts, Cashiers Checks, Money Orders and Travelers Checks Three $1,500 money orders bought with cash count as one $4,500 purchase. Splitting these across branches to duck the record is structuring, same as with a deposit.
Banks can also set their own rules about accepting cash. U.S. currency is legal tender for debts, but the Federal Reserve has clarified that no federal statute forces a private business, including a bank, to accept it, absent a state law that says otherwise.11The Fed. Is It Legal for a Business in the United States to Refuse Cash as a Form of Payment? Most banks readily accept large cash deposits from their own account holders, but some — particularly online-only banks — limit or restrict them. If you deal in large cash amounts regularly, check your bank’s policy before you show up with it.
