I am only commenting to warn others, as this is absolutely not true, and you have a dangerous misunderstanding of financial regulations. You would not be told if a report was filed, to do so is illegal.

> Generally, any person in a trade or business who receives more than $10,000 in cash in a single transaction or related transactions must complete a Form 8300, Report of Cash Payments Over $10,000 Received in a Trade or BusinessPDF. Form 8300 is a joint form issued by the IRS and the Financial Crimes Enforcement Network (FinCEN) and is used by the government to track individuals that evade taxes and those who profit from criminal activities. Although the cash reporting requirements apply to many types of businesses, auto dealerships frequently receive cash in excess of $10,000 and are required to comply with the filing requirements.
> Penalties. You may be subject to penalties if you fail to file a correct and complete Form 8300 on time and you cannot show that the failure was due to reasonable cause. You may also be subject to penalties if you fail to furnish timely a correct and complete statement to each person named in a required report. A minimum penalty of $25,000 may be imposed if the failure is due to an intentional or willful disregard of the cash reporting requirements.
> Penalties may also be imposed for causing, or attempting to cause, a trade or business to fail to file a required report; for causing, or attempting to cause, a trade or business to file a required report containing a material omission or misstatement of fact; or for structuring, or attempting to structure, transactions to avoid the reporting requirements. These violations may also be subject to criminal prosecution which, upon conviction, may result in imprisonment of up to 5 years or fines of up to $250,000 for individuals and $500,000 for corporations or both.
