Income Taxes Income Taxes
Our income tax provision for interim periods is determined using an estimated annual effective tax rate, adjusted for discrete items arising in that quarter.
For the three months ended March 31, 2025, our effective tax rate differs from the statutory rates primarily as a result of the differing apportionment rates for our state income taxes as well as an adjustment for equity compensation and equity method investments.
For the three months ended March 31, 2024, our effective tax rate differed from the statutory rates primarily as a result of the differing apportionment rates for our state income taxes as well as an adjustment for equity compensation.
Our net taxable income must be apportioned to various states based upon the income tax laws of the states in which we derive our revenue. Our NOL carryforwards will not always be available to offset taxable income apportioned to the various states. The states from which our refining, retail, and logistics revenues are derived are not the same states in which our NOLs were incurred; therefore, we expect to incur state tax liabilities in connection with our refining, retail, and logistics operations.
