you can deduct gambling losses to the extent of gambling winnings, but it's an itemized deduction, so you have to be able to use Schedule A to receive any tax relief.
and yes, you can use losses from all legal gambling activities to offset those winnings. You don't necessarily need losing tickets, a profit / loss statement from a casino or track or some organization that tracks your play will also suffice
willie, define legal
Is betting on sports ONLINE legal?
What if you report 25K in winnings and you had 20K in losses if you login to your sportsbook accounts and make a copy of your wager history(has date, wager, wo and lost, and the amount) would that be good enough to prove your losses?
Cant they say online sports betting is illegal and so you cant deduct your losses which means you have to pay taxes on 25K??
