This bill amends existing Oklahoma statutes to reauthorize income tax refund donations to two specific programs: the Indigent Veteran Burial Program and the Equipment and Capital Improvement Program of the Oklahoma Department of Veterans Affairs. The amendments specify that the donation provisions will apply to individual and corporate tax returns for the tax years 2017 through 2020, as well as for the tax year 2026 and subsequent years. The bill also updates statutory references and language, ensuring that the funds generated from these donations are appropriately allocated to their respective revolving funds for the benefit of veterans.

Additionally, the bill includes provisions for taxpayers who may make erroneous donations, allowing them to file claims for refunds within three years of the tax return due date. The reauthorization of the income tax checkoff for both programs is also included, ensuring that taxpayers can continue to support these initiatives through their tax returns. The act is set to take effect on July 1, 2026, and includes an emergency clause for immediate implementation upon passage and approval.
