Review for Comanche Nation Casino Review For Mustang Sports Grill Google User Jan 4 '18 at 4:05 I won a jackpot of 11000.00. I had the casino to withhold the taxes of 3100.00. I just received a letter from the IRS saying that I owe the 3100.00 because the casino never sent it to them. Had to send them a copy of my form from casino. Comanche Nation owes the IRS not me. Be careful if you win. Make sure they do the lawful thing or you will be on the hook for the taxes. So angry at yall. Not coming back. View full site to comment or like
