Which transaction should result in a SAR/STR filing?

RefThis transaction should result in a SAR/STR filing because it indicates possible structuring, which is a form of money laundering that involves breaking down large amounts of cash into smaller deposits to avoid detection or reporting requirements. Structuring is often done to conceal the source or destination of illicit funds, or to evade taxes, regulations, or sanctions. A small business owner who deposits checks just below the $10,000 USD threshold on a daily basis without providing a legitimate purpose raises a red flag for suspicious activity and should be reported to the relevant Financial Intelligence Unit.
