B11 Tax Incentive
Illinois provides a sales tax exemption (6.25%) for blends of biodiesel above B10 - correspondingly, most retail outlets in Illinois sell a B11 blend of biodiesel to take advantage of the incentive. This results in B11 selling for approximately 10-15 cents less than petroleum diesel. Illinois also has a partial sales tax exemption (20% off 6.25%) for biodiesel blends of 1-10%.
