A bill for an act modifying the sales or use tax refund for biodiesel production.

HF 2071 increases Iowa's tax refund for biodiesel producers from 4 cents to 5 cents per gallon. The refund amount is calculated by multiplying this new rate by the total gallons of biodiesel produced quarterly within the state. The bill also extends the program's expiration date from January 1, 2028, to January 1, 2031. This directly affects Iowa-based biodiesel producers by increasing their quarterly tax refund.
