If you are in the trade or business, and receive more than $10,000 in cash in one or a series of related transactions, then you are to file Form 8300 with the IRS within 15 days of the transaction. Most would think that this will not apply. But the definition of “cash” and related transactions” is broader than you might think. Cash includes cash, cashier’s checks, money orders, and traveler’s checks unless excluded in IRS Publication 1544. Related transactions can be one transaction, or a series that might be related to the same transaction such as monthly rents, purchases of products or supplies, and other transactions that can be tied together. The rule seems to be ‘when in doubt, report’. Give us a call to discuss in more detail.
