Title 31 › SUBTITLE IV — MONEY › CHAPTER 53 — MONETARY TRANSACTIONS › SUBCHAPTER II — RECORDS AND REPORTS ON MONETARY INSTRUMENTS TRANSACTIONS › § 5331
Anyone working in a business who gets more than $10,000 in coins or cash in one sale (or in two or more related sales), or who already must file a report under Internal Revenue Code section 6050I(g), must send a report to the Financial Crimes Enforcement Network (FinCEN) at the time and in the way the Secretary of the Treasury requires. The report must use the form the Secretary sets and include the payer’s name, address, other ID the Secretary asks for, the amount received, the date and type of the transaction, and any other information the Secretary requires (including who is filing). The rule does not apply to amounts banks report under section 5313, or to transactions that happen entirely outside the United States unless the Secretary’s rules say otherwise. “Currency” includes foreign money and, under Treasury rules, some monetary instruments up to $10,000, but not checks drawn on the writer’s account at certain regulated financial institutions.
