Legislation Signed in 2025 Reshapes Gambling Loss Deductions for 2026 Tax Year
Legislation enacted on July 4, 2025 introduced new limits on how gamblers can deduct losses beginning January 1, 2026, and observers note that these adjustments replaced the previous allowance of full deductions up to the amount of winnings. The One Big Beautiful Bill Act caps deductible losses at 90 percent while maintaining the overall ceiling at total winnings, which creates situations where individuals may face taxable gambling income even when their net results show losses or break even. Tax professionals have examined the measure and found it applies across different categories of gamblers with distinct reporting requirements.
Previous Framework for Gambling Deductions
Before the new rules took hold, recreational gamblers could claim losses as an itemized deduction on Schedule A provided those losses did not exceed reported winnings, and professional gamblers reported both winnings and losses on Schedule C along with other business expenses. That structure permitted complete offset of winnings by losses in most cases, yet the updated law narrows the percentage available for deduction while preserving the winnings cap. Data from the Internal Revenue Bulletin 2026-19 outlines these shifts and clarifies how the 90 percent limitation operates in practice for filers who itemize or treat gambling as a trade or business.
Application to Recreational and Professional Gamblers
Recreational gamblers continue to use Schedule A for itemized loss deductions, although the new 90 percent restriction means only a portion of qualifying losses becomes deductible even when winnings fully cover the original loss amount. Professional gamblers who report on Schedule C face the same percentage limit on losses while also incorporating allowable business expenses under the revised framework. Those who have reviewed the legislation point out that the distinction between the two groups remains important because professionals may offset additional costs separately, whereas recreational filers encounter the deduction solely through itemization on Schedule A.
Practical Effects on Taxable Income
Under the updated provisions, a gambler with equal winnings and losses may still report taxable income because only 90 percent of the losses qualifies for deduction. This outcome arises directly from the percentage reduction combined with the existing winnings cap, and examples reviewed by tax analysts show how the shortfall can generate a tax liability on what would have been a neutral result in prior years. The change affects both online and in-person activity reported to the IRS through forms such as W-2G, and filers must adjust their calculations accordingly when preparing returns for the 2026 tax year.
Implementation Timeline and Current Status in August 2026
The law took effect on the first day of 2026, so taxpayers filing returns in 2027 for the prior calendar year operate under these revised limits. By August 2026, tax preparation services have incorporated the new percentage cap into their guidance materials, and accountants report increased inquiries from clients who track gambling activity throughout the year. The Internal Revenue Bulletin 2026-19 provides detailed examples that illustrate how the 90 percent figure interacts with winnings caps across various scenarios, helping filers avoid underreporting or over-deducting on their schedules.
Reporting Requirements and Documentation
Accurate recordkeeping remains essential because the IRS continues to require substantiation of both winnings and losses through logs, receipts, and statements from gambling establishments. Recreational filers must still itemize on Schedule A to claim any deduction, while professionals list losses and expenses on Schedule C subject to the same percentage limitation. Those who have studied the transition note that failure to apply the 90 percent cap correctly can lead to adjustments during audits, particularly when reported losses approach or match total winnings.
Conclusion
The One Big Beautiful Bill Act established a clear shift in how gambling losses factor into federal tax calculations starting in 2026, and the 90 percent limitation combined with the winnings cap produces measurable differences for both recreational and professional participants. Taxpayers who engage in gambling activity now calculate deductions with this reduced percentage in mind, and the distinction between Schedule A and Schedule C reporting continues to guide proper placement of figures on returns. As the 2026 tax year progresses, filers and preparers apply these rules consistently to ensure compliance with the updated statutory requirements.
