HB 2646 amends Oklahoma's tax code to adjust how taxable income is calculated for corporations and individuals, primarily affecting businesses and residents filing state tax returns. Key provisions update rules for net operating loss carryforwards/carrybacks, clarify treatment of interest income from state obligations, and specify allocation methods for income from property (real, intangible) and business activities. The bill aligns some Oklahoma tax calculations with federal Internal Revenue Code rules while maintaining state-specific adjustments. This bill was vetoed by the governor on May 30, 2025, with the veto taking effect June 15, 2025, so these changes never took effect.

MINOR
This bill version was amended to reflect changes made during Senate floor consideration, primarily updating the document header and adding a new provision regarding how capital gains from selling publicly traded partnership interests are taxed. The substantive tax calculation rules remain largely the same, but the Senate version adds specific language about how these partnership gains should be treated in apportionable income.
Scope change
The bill's scope remains focused on Oklahoma state income tax calculations, but the Senate amendment adds a specific rule for taxing gains from publicly traded partnerships, potentially affecting how investors in these entities are taxed.

Document headers and formatting were updated to reflect Senate floor version rather than House floor version, including adding the Senate sponsor name and changing page headers.
