I recently took a trip to Las Vegas and made a nice sum of money. I kept that money in my account at the casino and took it all when I left to fly back home. Now my concern is that according to Regulation 6A, transactions of over $10,000 have to be reported. In the end, the withdrawal was well over that sum. The amount I withdrew broke down to my initial bankroll, some of my friends' money, and my winnings. So, the money does not completely represent my winnings. Is this withdrawal going to reported as winnings? When I withdrew my money, they asked for my Social Security number. I asked if I needed to give it to them and they said no, so I didn't give it to them.
Can someone please inform me about what they will do and perhaps advise me as to what I should do.
