Businesses, including sole proprietors, in any U.S. possession or territory must report a cash transaction exceeding $10,000. The transactions are reported on Form 8300, which must be filed within 15 days of the transaction. A transaction can include two or more related transactions if the recipient knows, or has reason to know, that each transaction is one of a series of connected transactions. Transactions conducted between a payer (or its agent) and the recipient within a 24-hour period are considered related. Cash includes coins and currency (domestic and foreign), cashier’s checks, bank drafts, traveler’s checks, and money orders. U.S. possessions and territories include American Samoa, the Commonwealth of Northern Mariana Islands, Guam, Puerto Rico, and the U.S. Virgin Islands. Businesses required to file Form 8300 can include pawnbrokers, attorneys, real estate brokers, insurance companies, and travel agents, as well as those that sell jewelry, furniture, boats, aircraft, or automobiles.
