Failing to Report Gambling Winnings or Claiming Big Losses

Whether you’re playing the slots or betting on the horses, one sure thing you can count on is that Uncle Sam wants his cut. Recreational gamblers must report winnings as other income on the front page of the 1040 form. Professional gamblers show their winnings on Schedule C. Failure to report gambling winnings can draw IRS attention, especially because the casino or other venue likely reported the amounts on Form W-2G. Claiming large gambling losses can also be risky. You can deduct these only to the extent that you report gambling winnings. And the costs of lodging, meals and other gambling-related expenses can only be written off by professional gamblers. Writing off gambling losses but not reporting gambling income is sure to invite scrutiny. Also, taxpayers who report large losses from their gambling-related activity on Schedule C get an extra look from IRS examiners, who want to make sure that these folks really are gaming for a living.
