CTR

A currency transaction report, or CTR, is a report that US financial institutions generally must file with FinCEN for cash transactions exceeding $10,000 in a business day. It supports anti-money-laundering monitoring and is not itself an accusation of wrongdoing.

In identity verification and financial-crime compliance, a CTR is a regulated reporting record tied to a customer and a significant cash transaction. It helps authorities identify potential money laundering, tax evasion, or other illicit use of cash.

CTR most commonly refers to the US Currency Transaction Report. Similar reporting duties exist elsewhere, but thresholds, forms, and responsible agencies differ across jurisdictions, including EU member states.

When a CTR is required

US banks and certain other financial institutions generally file a CTR when a person conducts cash transactions totaling more than $10,000 during one business day. The requirement can apply to related transactions that the institution knows are connected.

• Cash includes US or foreign currency, not ordinary wire transfers, checks, or card payments.
• Institutions identify the person conducting the transaction and, where relevant, the person or business on whose behalf it is conducted.
• Reports are filed with the Financial Crimes Enforcement Network, or FinCEN, a bureau of the US Treasury Department.

Role in identity verification

A CTR requires reliable customer identification information, such as name, address, date of birth where applicable, and taxpayer or other identifying number. Financial institutions use customer due diligence, document checks, and other verification controls to collect and validate that information.

CTR versus suspicious activity reporting

A CTR is threshold-based: a qualifying cash transaction generally triggers reporting even when there is no suspected crime. A suspicious activity report, or SAR, is based on suspected illegal or unusual activity and can be required at lower amounts or without a monetary threshold.

Breaking up cash deposits or withdrawals to avoid CTR reporting, known as structuring, may itself be unlawful.
