When Should a CTR Be Completed: $10,000 Rule and 15-Day Deadline

A Currency Transaction Report should be completed whenever a financial institution handles more than $10,000 in cash by or on behalf of the same person during a single business day, and the completed report must be filed electronically with FinCEN within 15 days of the transaction.¹² The rule catches a single large transaction or several smaller ones that combine past the threshold, and the obligation rests on the institution, not the customer.

The $10,000 Cash Trigger

The threshold is a bright line. Every covered financial institution must report each deposit, withdrawal, currency exchange, or other transfer involving more than $10,000 in currency.¹ There is no discretion. A cash transaction of $10,000.01 requires a report; $10,000 flat does not.

The requirement reaches beyond traditional banks. Federal regulations define “financial institution” to include banks, credit unions, brokers and dealers in securities, money services businesses, casinos and card clubs with more than $1 million in gross annual gaming revenue, futures commission merchants, introducing brokers in commodities, and mutual funds.³ Each is independently responsible for identifying reportable transactions.

What Counts as Cash

Only physical money triggers a CTR. Federal regulations define currency as coin and paper money of the United States or any other country that is designated as legal tender and circulates as a medium of exchange in its country of issuance.⁴

Personal checks, wire transfers, money orders, cashier’s checks, and credit card payments are not currency for CTR purposes. A $15,000 personal check deposit does not require a report. The same $15,000 deposited in bills does.

Foreign cash is converted to U.S. dollars using the exchange rate in effect on the business day of the transaction, and the institution chooses the rate source.⁵

Same-Day Aggregation

A CTR is not limited to one large transaction. If a customer conducts multiple cash transactions during a single business day and the institution knows those transactions are by or on behalf of the same person, the institution must combine them. When the combined total exceeds $10,000 in either cash-in or cash-out, a CTR is required.⁶

A customer who deposits $6,000 in cash in the morning and another $5,000 that afternoon has generated an $11,000 reportable transaction. This aggregation runs across every branch of the same institution, so visiting different locations on one day does not avoid the report. Cash deposited overnight or over a weekend is treated as received on the next business day.⁶

Joint Accounts

Cash deposits into a joint account are treated as made on behalf of every account holder, because each holder has access to the balance. If John deposits $5,000 and Jane later deposits $7,000 into a shared account the same day, the institution must file a CTR listing both John and Jane, each as a person conducting a transaction and as a person on whose behalf a transaction was conducted.⁷

Structuring Is a Federal Crime

Breaking cash transactions into smaller amounts to stay under $10,000, known as structuring, is a federal crime even when the money itself is legal. It is unlawful to structure or help structure any transaction for the purpose of evading CTR reporting requirements.⁸ Depositing $9,500 in cash on three consecutive days specifically to avoid triggering a report can lead to prosecution regardless of whether the funds are clean.

Structuring carries up to five years in prison, or up to ten years when the conduct is connected to another federal crime or is part of a pattern involving more than $100,000 within 12 months. Structured funds are subject to seizure and civil forfeiture. Institutions use automated systems that track customer identifiers, joint account access, and transaction patterns to flag deposits or withdrawals repeatedly landing just under $10,000.

The 15-Day Filing Deadline

Once a transaction is reportable, the institution has 15 days from the transaction date to file the CTR electronically through the FinCEN BSA E-Filing System.² The report is submitted on FinCEN Form 112. After a successful submission, the system generates a confirmation with a BSA Identifier number, which the institution should keep as proof of timely filing.

Fixing an Error After Filing

A CTR filed with errors or missing information can be corrected. For an individual filing, the preparer selects the “Correct/amend prior report” option and enters the original Document Control Number or BSA Identifier. For a batch filing, a specific code flags the record as an amendment.⁹

After submitting the amended report, the institution must send FinCEN a confirmation letter explaining why the original was incorrect, along with a list of affected reports showing their BSA Identifiers, transaction dates, and amounts. Copies also go to the federal and state agencies that examine the institution’s BSA compliance program. This letter is due within 60 calendar days of FinCEN’s determination, unless FinCEN gives other instructions.⁹

When a CTR Is Not Required: Exempt Persons

Some customers can be designated as “exempt persons,” which removes the CTR filing obligation for their routine cash transactions. Exemptions fall into two categories.

Phase I

Phase I exempt persons are automatically eligible and include other banks (for their domestic operations), U.S. government departments and agencies at the federal, state, or local level, and entities that exercise governmental authority. Banks do not need to file a designation form for Phase I exempt persons or for transactions with any of the twelve Federal Reserve Banks.¹⁰

Phase II

Phase II exempt persons require a formal designation and include companies listed on the New York Stock Exchange or NASDAQ National Market, subsidiaries of those listed companies where the parent holds at least 51 percent ownership, qualifying non-listed businesses that frequently conduct cash transactions over $10,000, and payroll customers that routinely withdraw large amounts of cash to pay employees.¹⁰

To designate a Phase II exempt person, the bank files FinCEN Form 110 within 30 calendar days after the first reportable cash transaction with that customer. For non-listed businesses and payroll customers, the customer must have maintained an account at the bank for at least two months, unless the bank conducts a risk-based assessment and forms a reasonable belief that the customer has a legitimate business purpose for frequent cash transactions. The bank must document the basis for every exemption and review Phase II eligibility at least annually.¹⁰¹¹

What Missing the Filing Costs

Penalties depend on whether the failure was negligent or willful and whether it was isolated or part of a pattern.

Civil

An institution that negligently fails to file a CTR or files one with errors faces a civil penalty of up to $500 per violation. A pattern of negligent violations can add a penalty of up to $50,000 on top of the per-violation fines.¹²

Willful violations are more expensive. A financial institution, or any partner, director, officer, or employee who willfully violates BSA reporting requirements, faces a civil penalty of up to the greater of $25,000 or the amount involved in the transaction, capped at $100,000.¹²

Criminal

Willful failures can also be prosecuted. A person who willfully fails to file a required CTR faces a fine of up to $250,000, imprisonment for up to five years, or both. If the violation occurs while the person is also violating another federal law, or as part of a pattern of illegal activity involving more than $100,000 in a 12-month period, the maximum fine rises to $500,000 and the maximum prison sentence to ten years.¹³
