Yes, car dealers must report cash sales over $10,000 to the IRS using Form 8300, a legal requirement to combat money laundering and tax evasion, requiring customer identification and filing within 15 days. This applies to single transactions or related transactions totaling over $10,000 and is a standard procedure for significant cash purchases, even for legitimate buyers.

Do dealerships report cash payments?

Dealers must report to IRS (using IRS/FinCEN Form 8300) the receipt of cash/cash equivalents in excess of $10,000 in a single transaction or two or more related transactions. By January 31 of the following year, dealers also must notify the customer in writing that a cash report was filed.

How much cash can you put down on a car without it being reported?

Once the dealership receives cash exceeding $10,000, a Form 8300 must be filed. The deal not going through may in fact be an attempt to launder illegal funds. If $10,000 or less was received by the dealer and the deal was cancelled, the dealer may voluntarily file a Form 8300 if the transaction appears suspicious.

Should you tell the dealership you're paying cash?

No, you generally should not tell a car salesman you're paying cash upfront; instead, negotiate the vehicle's total price as if you were financing, and only reveal your cash payment method after the deal (the "out-the-door" price) is finalized, as dealers make significant profit on financing, so knowing you're paying cash removes their incentive to negotiate on the car's price. Reveal you're paying cash later to avoid them marking up the price to compensate for lost financing profit.
 

Why don't dealers want you to pay cash?

Dealerships don't want you to pay cash because they don't earn a commission on arranging financing. If you qualify for in-house financing, the profits they miss out on increase since they don't have to work with a third-party lender.
