The law requires that trades and businesses (such as auctioneers) report cash payments of more than $10,000 to the federal government by filing IRS/FinCEN Form 8300, Report of Cash Payments Over $10,000 Received in a Trade or Business.
This “Over $10,000” can be one cash payment in excess of $10,000 or a series of cash payments from the same buyer over a year exceeding $10,000.
“Cash” in this regard is considered coins and currency of the United States and a foreign country. Cash may also include cashier’s checks, bank drafts, traveler’s checks, and money orders with a face value of $10,000 or less.
“Cash” does not include personal checks drawn on the account of the writer nor a cashier’s check, bank draft, traveler’s check or money order with a face value of more than $10,000.
One transaction is generally deemed any “cash” received within a 24-hour period. Related transactions can take place over a year following the first cash payment.
Generally, a business must file Form 8300 within 15 days after they receive over $10,000 in cash. If the 15th day falls on a Saturday, Sunday, or holiday the business must file the report on the next business day.
