710:50-15-69.1 Add-back of federal depreciation for Oklahoma income tax purposes

(a) Taxpayers have the option to immediately and fully deduct the cost of qualified property and qualified improvement property for income tax purposes. This deduction is eligible for one hundred percent (100%) bonus depreciation and can be claimed as an expense in the tax year when the property is placed in service. This deduction remains available in subsequent years, regardless of changes to federal law related to cost recovery amortization beginning January 1, 2023. (b) If a taxpayer chooses to immediately and fully expense qualified property or qualified improvement property, any depreciation claimed under this provision cannot duplicate the depreciation or bonus depreciation claimed on their federal income tax return. For tax returns filed on or after January 1, 2023, the taxpayer must increase their federal taxable income by the amount of depreciation received under the Internal Revenue Code for the property for which the immediate and full expensing election was made on the Oklahoma income tax return. If a taxpayer's federal taxable income is not increased as required by this provision before October 1, 2023, they must file an amended return reflecting the increase by June 30, 2024. The Tax Commission will not impose penalties or interest if a correct amended return is filed within the specified timeframe. (c) The taxpayer's decision to recover investment costs through immediate expensing in the year of the investment or through amortization over a schedule is irrevocable, unless specifically allowed by the Tax Commission.
