What is a Wagering loss deduction?

A wagering loss deduction is a federal itemized deduction that allows taxpayers to offset gambling winnings with gambling losses and related expenses, subject to specific limitations. Under the One Big Beautiful Bill Act, the deduction is permanently capped at 90% of total gambling winnings for tax years beginning after December 31, 2025. This cap applies to both recreational and professional gamblers, ensuring that at least 10% of gambling winnings remain taxable. Qualifying losses include casino games, sports betting, poker tournaments, lottery tickets, and horse racing, as well as gambling-related travel and business expenses. Taxpayers must maintain detailed documentation, including daily gambling logs, Form W-2G statements, and expense receipts, to support deduction claims. Strategic coordination with Traditional 401k contributions can help offset increased tax liability from the modified cap.
