Answer:
There are no taxes on table games winnings so you will not get a W2-G but the casino may issue a 1099 form at the end of the year if your winnings exceed $600. They will have your tax info if you cash winning of more than $10,000 because casinos must file Cash Transaction Reports as they are subject to the "money-laundering rules." Casinos must report aggregate cash transactions of $10,000 or more in any one day to the IRS.
