I know there will be doubters because I'm not computer savvy enough to upload the proof but here we go! Won two nine teamers weeks 1 and 2 in NV and was shocked to get handed W-2G forms for the IRS. It's not the dollar amount of the win that triggers an IRS notification but the fact that you surpassed 300-1 payout odds. Will stick to 8-teamers from now on. It wasn't easy street, I spent about $400 to win $840 and $700 to win $1700. Unless I use a players card everywhere all the IRS will see is my gains and not my losses. Will stick to 8-teamers I guess and stay under the radar.
