Allowing an itemized deduction for certain wagering losses for individual income tax purposes.

This bill allows Kansas residents who itemize deductions on their federal tax returns to deduct 100% of their gambling losses as part of their state itemized deductions, effective for tax years beginning January 1, 2025. It directly affects Kansas taxpayers who itemize federal deductions and have documented gambling losses (e.g., from casinos, sports betting, or lotteries). The change adds gambling losses to the list of allowable itemized deductions - alongside charitable contributions, medical expenses, and property taxes - mirroring federal tax treatment under Section 165(d) of the Internal Revenue Code. This is a policy change to the state tax code, not a procedural or commemorative measure.
