SB 299 Oklahoma Senate · 2025 Regular Session

Income tax; modifying certain apportionment factor for calculation of Oklahoma taxable income. Effective date.

SB 299 modifies how Oklahoma calculates taxable income for businesses by changing the rules for net operating loss (NOL) deductions. It specifically adjusts how businesses can carry forward or back federal NOLs to offset Oklahoma taxable income, creating a separate "Oklahoma net operating loss" for state tax purposes. For tax years beginning after December 31, 2007, and ending before January 1, 2009, the bill limits NOL carrybacks to two years. This bill directly affects businesses with federal NOLs operating in Oklahoma, altering their state tax calculations without changing tax rates or exemptions.
