55. Structuring (Smurfing)

Financial Transactions

Structuring, also known as “smurfing,” is the practice of breaking down large financial transactions into multiple smaller transactions to deliberately avoid triggering BSA reporting requirements such as CTRs. In a casino context, structuring typically involves a patron conducting a series of cash buy-ins or chip redemptions, each kept just under $10,000 to evade CTR filing. Examples include redeeming $9,000 in chips at one cage window and $6,000 at another, or making repeated $9,000 cash deposits over multiple days. Structuring is itself a federal crime under 31 U.S.C. § 5324, regardless of whether the underlying funds are from illegal activity. Casinos must have systems to detect structuring patterns and file SARs when identified.

In practice

FinCEN specifically identifies structuring as a reportable activity. Even if the funds are legally obtained, deliberately evading reporting thresholds is a criminal offense. Casinos should continue transactions and file SARs without alerting the patron.
