This bill, known as the "End Polluter Welfare for Enhanced Oil Recovery Act of 2026," proposes significant changes to the Internal Revenue Code concerning tax credits related to oil recovery and carbon capture. Its primary goal is to curtail federal subsidies for enhanced oil recovery (EOR) activities by amending existing tax provisions. Specifically, the bill amends Section 45Q of the Code to **eliminate the use of carbon oxide as a tertiary injectant** for enhanced oil recovery for any qualified facility constructed after the bill's enactment date. This means new carbon capture projects would no longer receive tax credits under Section 45Q for carbon dioxide used in EOR. Furthermore, the legislation **strikes Section 43** of the Internal Revenue Code, thereby repealing the existing tax credit for enhanced oil recovery entirely, along with several conforming amendments. These changes are set to apply to taxable years beginning after the date of enactment.
