Revenue and taxation; Oklahoma taxable income; Oklahoma adjusted gross income; effective date.

HB 2968 proposes changes to how Oklahoma calculates taxable income for corporations and adjusted gross income for individuals. It specifically adds interest income from state and local bonds (not already exempt) to taxable income, adjusts federal net operating loss deductions based on Oklahoma-sourced losses, and revises rules for allocating income from property and business activities. These changes would directly affect all Oklahoma taxpayers by altering their state tax calculations. The bill modifies existing tax code provisions but does not specify an effective date in the provided text.
