E85 in Iowa: Frequently Asked Questions

How much ethanol does Iowa produce?

Iowa produced 4.6 billion gallons of ethanol in 2025 — roughly 28% of total U.S. output — across 42 refineries with a combined capacity above 5 billion gallons per year, according to the Iowa Renewable Fuels Association. Iowa processed about 1.5 billion bushels of corn for ethanol in 2025, and biofuels contribute roughly $5.4 billion to state GDP. Iowa remains the nation's #1 ethanol-producing state, though output has been flat for three years.

Are Iowa retailers paid to sell E85?

Yes. The Iowa E85 Gasoline Promotion Tax Credit pays retailers $0.16 per gallon of E85 sold and is active through January 1, 2028 (claimed on Form IA 135, credit code 55). The Iowa Renewable Fuels Infrastructure Program adds cost-share grants for E15, E85, and biodiesel equipment — the state has invested over $63 million since 2006, matched by more than $270 million in private funding, with 108 new projects approved in December 2025.

Does Iowa make state employees use E85?

Yes. Iowa Code requires state-fleet flex-fuel vehicles to fuel with E85 where reasonably available, and state diesel vehicles to use biodiesel blends of B2 through B99. The policy, combined with retailer incentives and a dense Casey's General Stores network (headquartered in Ankeny), underpins Iowa's strong E85 availability in every major metro.
