Gambling winnings versus losses

[Jeter2016]

I have a client who had gambling slips of 90,000.00
His win loss statement is showing a loss of (50,000.00).
Does this mean that he actually has gambling losses of 140,000.00 and can I take the losses on Schedule A up to the 90,000.00.
Not sure how to handle this.
Thanks

There is more to this than just looking at the win/loss statement. Your client has to report all winnings, even those not on W-2G's. And you can only deduct the losses up to the amount of the winnings.
The win/loss statement should show each day's activities. In the last few years, the casinos have stopped issuing those and are just issuing one that just shows the net win or loss for the year.
