Senate Bill 600 mandates the governor of Wisconsin to elect participation in the federal tax credit program for contributions to scholarship granting organizations, as established by the federal One Big Beautiful Bill Act of 2025. This election must occur by July 1, 2026, and will enable the state to participate in the program starting with the taxable year after December 31, 2026. The bill also requires the Department of Administration to compile and submit an annual list of qualifying scholarship granting organizations to the U.S. Secretary of the Treasury, ensuring compliance with federal regulations to maintain eligibility for the tax credit.

Additionally, the bill creates a new statute, 16.004 (25), which outlines the responsibilities of the Department of Administration in relation to the federal tax credit program. This includes the requirement to publish the list of qualifying organizations on the department's website and to certify its authority to submit this list to the U.S. Secretary of the Treasury. The provisions aim to facilitate the state's participation in the federal program and support contributions to scholarship granting organizations that provide funding for eligible students.
