We just sold my wife's car today for cash. We took the car to our credit union and met the seller to complete the sale. He brought cash, we did the paperwork in the lobby and then walked up to the teller to have the cash counted and deposited into our account to pay off the loan. The CU advised us that a "Currency Transaction Report" (CTR) had to be filed since the cash amount was over $10,000. He did it electronically, we walked out and went online to transfer the funds to the out-of-town CU to pay the loan. Has anyone ever done a CTR before? What is done with it? Is there some sort of a tax impact for this transaction?
