What amount can Shannon deduct as gambling losses for the year on Schedule A after reporting her gambling winnings?

In tax law, gambling losses can only be deducted to the extent of gambling winnings. This means that if no gambling winnings were reported during the tax year, no deduction for gambling losses can be claimed. Therefore, if Shannon did not report any gambling winnings, the amount she can deduct for her gambling losses would indeed be $0. It's essential to note that the losses should be documented with appropriate records and cannot exceed the total amount of reported gambling income, ensuring the taxpayer only deducts what is permissible under the IRS rules.
