Currency Transaction Report Requirements

What a currency transaction report requires: the $10,000 line, aggregation across branches, the 15-day filing deadline, and the internal controls the FFIEC manual expects.

What a currency transaction report is and when one is required

A currency transaction report is a filing a bank sends to FinCEN. It records cash that moved through the bank above a set line. FinCEN's alert says a currency transaction report covers a currency transaction of more than $10,000.

The report is part of the bank secrecy act framework. It is not about suspicion. A CTR can cover a deposit that raises no suspicion at all. The trigger is the amount, and the form of it.

What counts as a transaction in currency, and what does not

The definition is narrow. § 1010.100 says a transaction in currency means a transaction involving the physical transfer of currency from one person to another. Cash handed over the counter counts. Cash in a night drop counts.

Checks and wires do not. § 1010.100 says a transfer of funds by bank check, bank draft, wire transfer, or other written order is not a transaction in currency. So a wire is not a transaction in currency.

The rule also says what counts as a monetary instrument. § 1010.100 says monetary instruments include currency and traveler's checks in any form. But it says monetary instruments do not include warehouse receipts or bills of lading.

The reporting threshold and how multiple transactions are added together

FinCEN's alert puts the line at more than $10,000 in currency.

Smaller amounts can cross it together. FinCEN's alert says multiple transactions may be added together to decide whether the reporting threshold has been met.

Branch offices and aggregation across the bank

A customer does not have to use one window. § 1010.313 says a financial institution includes all of its domestic branch offices for currency transaction reporting. The FFIEC manual says a bank includes all of its domestic branch offices, so branch office transactions must be aggregated.

Cash taken in at any branch counts for the bank as a whole.

There is a timing rule for off-hours deposits. § 1010.313 says deposits made at night or over a weekend or holiday are treated as if received on the next business day. A weekend night drop counts on the next business day.

Commonly owned businesses: when transactions combine and when they do not

One person can own several shops, each with its own accounts. Do their cash deposits add together?

Not automatically. The FFIEC manual says a bank must not automatically combine the currency transactions of separately incorporated businesses just because one person owns them all. The bank must decide if commonly owned businesses really run on their own. It uses what it learns in the ordinary course of business.

If the bank finds the businesses are independent, it does not have to add their transactions together. If the bank finds they are not independent, it should combine their transactions going forward.

The ownership alone does not answer it.

Filing the report: the BSA E-Filing System and the 15-day deadline

The FFIEC manual says all CTRs must be filed through FinCEN's BSA E-Filing System. Forms for reporting currency transactions may be obtained from the BSA E-Filing System.

The deadline is fixed. The FFIEC manual says a completed CTR must be electronically filed with FinCEN within 15 calendar days after the date of the transaction.

Blank fields are a problem. The FFIEC manual says the BSA E-Filing System does not accept CTR filings in which fields marked as critical are left blank. The FFIEC manual says FinCEN expects banks to give the most complete filing information available, whether or not a field is technically critical.

The system also gives feedback. The FFIEC manual says FinCEN's BSA E-Filing System allows for tracking of filings and sends users acknowledgement notifications and other correspondence. If FinCEN sends a letter about data errors, the bank should do what FinCEN asks. If FinCEN says a bank must backfile or amend, the bank should follow the steps on FinCEN's website.

Record retention

The FFIEC manual says the bank must retain copies of CTRs for five years from the date of the report. That is separate from the clock on the filing itself.

Internal controls for currency transaction reporting

The FFIEC manual says examiners should assess the adequacy of the bank's policies, procedures, and processes for reporting currency transactions. It also says a bank's internal controls should keep it meeting CTR rules day after day.

The manual names specific controls. It says employees who complete CTRs generally should not also decide to file the reports. It says controls may include senior management approval for staff actions that override currency aggregation systems. A BSA compliance officer may give that approval too.

The point of these controls is simple. A system that adds transactions can be switched off by someone. The manual wants that switch watched.

Structuring: the offence the rule prohibits

Structuring is an offence of its own. § 1010.314 says no person may cause a domestic financial institution to fail to file a required currency transaction report to evade reporting rules. It also says no person may cause a domestic financial institution to file a currency report with a material omission or misstatement of fact.

The bank's job is to detect and report it.

Exemptions

FinCEN's alert says banks file a report to exempt certain customers from currency transaction reporting requirements.

The exemption is a filing of its own.
