The Department has submitted the following proposed rule to the Iowa Legislature, available for public comment through May 24, 2022. See individual notice for details:

  • Excise Tax Rate on Motor Fuels
    This proposed rulemaking amends subrule 68.2(1) to adjust the excise tax rate on biodiesel blended fuel rated B-11 or higher from 30.4¢ per gallon (ending June 30, 2022) to 30.1¢ per gallon (beginning July 1, 2022), pursuant to the formula prescribed by Iowa Code section 452A.3. The distribution percentage for biodiesel blended fuel rated B-11 or higher for calendar year 2021 is 57.75 percent, a decrease from the 2020 distribution percentage of 61.49 percent. As a result, pursuant to Iowa Code section 452A.3(3)“a”(2), in fiscal year 2023, the excise tax rate for biodiesel blended fuel rated B-11 or higher will decrease as noted above. Tax rates for all other fuel types will remain unchanged for fiscal year 2023.
