Two people (someplace in the US) are talking and saying this (approximately; I don't recall the exact figures they said): A- If the casino gives you a W2g, then you have to report the win to the IRS. B- But I didn't get a W2g because I had a bunch of little wins. Back and forth to the cashier and it totaled about $2000. A- Don't worry; if you don't report it, they won't find out. B- Only that I banked it: 20, $100 bills. Won't the bank find that suspicious? A- The bank's not going to worry about where you got your money. They only report in excess of $10,000 -- or if you appear to be a gang member. You're not a gang member. B- But ... A- Stop worrying about it. No one's going to find out. People do this all the time.
