The Company recorded a 2022 income tax benefit of $78 million primarily as a result of state legislative changes and a change in the valuation of deferred taxes as a result of filing the 2021 tax returns. In 2021, the Company recorded an income tax benefit of $48 million primarily as a result of favorable state legislative changes, additional tax benefits associated with the vesting of share-based awards and adjustments to deferred taxes as a result of filing the 2020 state tax returns. In 2020, the Company recorded an income tax benefit of $30 million primarily as a result of the additional tax benefit associated with vesting of share-based awards and the resolution of certain tax matters.

Income tax expense reconciled to the tax computed at statutory rates is presented in the following table.

The Company files a consolidated federal income tax return, which includes its principal domestic subsidiaries. CSX and its subsidiaries are subject to U.S. federal income tax as well as income tax of multiple state jurisdictions. CSX participated in a contemporaneous IRS audit of tax years 2022 and 2021. Federal examinations of original federal income tax returns for all years through 2020 are resolved.

As of December 2022 and 2021, the Company had approximately $18 million and $18 million, respectively, of total unrecognized tax benefits as a result of uncertain tax positions. Net tax benefits of $14 million and $15 million as of December 2022 and 2021, respectively, could favorably impact the effective income tax rate in each year. The Company does not expect that unrecognized tax benefits as of December 2022 for various state and federal income tax matters will significantly change over the next 12 months. The final outcome of these uncertain tax positions is not yet determinable. There were no material changes to the total gross unrecognized tax benefits and prior year audit resolutions of the Company during the year ended December 2022.
    
CSX’s continuing practice is to recognize net interest and penalties related to income tax matters in income tax expense. Accrued interest and penalties were not material as of December 2022 or 2021. Additionally, expenses from changes to the reserves for interest and penalties were not material in 2022, 2021 or 2020
