HB2646 amends Oklahoma’s income tax adjustment statute to remove, for certain tax years, the cap on itemized wagering losses that may be deducted when calculating Oklahoma taxable income. The bill specifically updates 68 O.S. Section 2358 to provide that, for tax years beginning after December 31, 2024, wagering losses deductible under federal law are excluded from the state’s $17,000 itemized deduction cap. In practical terms, taxpayers who itemize may be able to deduct more gambling losses on their Oklahoma return than they could under prior law, subject to the federal limitation that wagering losses may only offset wagering gains.
The measure also makes a series of technical updates to statutory language and references throughout the income tax adjustment section, including conforming cross-references and wording changes. It does not create a new tax category or overhaul the income tax code; rather, it modifies an existing deduction rule within a long and detailed statute governing how federal income and deductions are adjusted to determine Oklahoma taxable income and adjusted gross income.
The bill’s impact is focused on individual taxpayers who report gambling activity and itemize deductions, as well as on the Oklahoma Tax Commission, which will need to administer the revised treatment beginning with the 2025 tax year. Because the change applies only to wagering losses and only for tax years beginning after December 31, 2024, it is a targeted revenue and tax conformity adjustment rather than a broad tax-rate change. The bill also preserves the rest of the state’s itemized deduction limitation and the many existing Oklahoma-specific additions and subtractions in the income tax code.
Overall sentiment appears generally favorable but not unanimous. The bill advanced with strong majorities in both chambers, including 68-25 on House third reading, 32-15 on Senate third reading, and 61-25 and 38-9 on the final fourth readings in the House and Senate, respectively. Those vote margins suggest broad support for the wagering-loss change, while the repeated minority opposition indicates some concern about reducing state tax revenue or about the policy choice to expand deductibility for gambling losses.
The main point of contention is likely the tax policy itself: supporters appear to view the bill as a fairness or conformity measure for taxpayers with gambling losses, while opponents may see it as a revenue loss or as preferential treatment for wagering activity. No committee transcript was provided, so the record does not show detailed arguments, but the vote pattern indicates the issue was somewhat divisive rather than purely technical. The bill was ultimately enacted with an effective date of November 1, 2025.
HB2646 amends 68 O.S. Section 2358, the statute governing Oklahoma’s adjustments to federal taxable income and adjusted gross income. Its principal legal effect is to remove the itemized-deduction cap, for tax years beginning after December 31, 2024, as it applies to wagering losses deductible under 26 U.S.C. Section 165(d). The bill also updates statutory language and references within the income tax adjustment provisions. The change affects individual income taxpayers who itemize deductions and report gambling activity, and it requires the Oklahoma Tax Commission to apply the revised deduction treatment beginning with the 2025 tax year.
The bill appears to have received generally positive support, with clear majorities in both chambers and final passage in each chamber. The vote margins show that the measure was acceptable to most lawmakers, though not overwhelmingly so, indicating some reservations remained. In the absence of committee testimony, the voting history is the best indicator of sentiment, and it suggests the bill was viewed as a targeted tax adjustment rather than a controversial overhaul.
The main contention is the policy choice to expand the deductibility of wagering losses by removing the state itemized-deduction cap for those losses. Supporters likely viewed the change as a conformity or fairness measure for taxpayers with gambling winnings and losses, while opponents likely objected on revenue grounds or as a benefit tied to gambling activity. The opposition was not confined to one chamber, as the bill drew notable minority no votes in both the House and Senate throughout final passage.
