All gambling winnings, including lottery tickets, must
be reported as ordinary income. Gambling losses, including losing lottery
tickets, are deductible but (1) only up to the amount of your winnings and (2)
only if you itemize deductions.
If you claim the standard deduction, you are still
obligated to report and pay tax on all winnings during the year. However,
you will not be able to deduct any of your losses.
For more information, please see this
TurboTax Guide Gambling winnings and losses.
