701—52.31 (422) Biodiesel blended fuel tax credit. Effective for tax years beginning on or after January 1, 2006, a retail dealer of biodiesel blended fuel may claim a biodiesel blended fuel tax credit. “Biodiesel blended fuel” means a blend of biodiesel with petroleum-based diesel fuel which meets the standards provided in Iowa Code section 214A.2. The biodiesel blended fuel must be formulated with a minimum percentage of 2 percent by volume of biodiesel, if the formulation meets the standards provided by section 214A.2, to qualify for the tax credit. In addition, of the total gallons of diesel fuel sold by the retail dealer, 50 percent or more must be biodiesel blended fuel to be eligible for the tax credit for tax years beginning prior to January 1, 2009. For tax years beginning on or after January 1, 2009, the biodiesel blended fuel tax credit is calculated separately for each retail motor fuel site for which 50 percent or more of the total gallons of diesel fuel sold at the motor fuel site was biodiesel blended fuel.
The tax credit equals three cents multiplied by the qualifying number of biodiesel blended fuel gallons sold by the taxpayer during the tax year. For purposes of this rule, tank wagon sales are considered retail sales. The credit is calculated on Form IA8864.
Any credit in excess of the taxpayer’s tax liability is refundable. In lieu of claiming the refund, the taxpayer may elect to have the overpayment credited to the tax liability for the following tax year.
Example:  A taxpayer operated four retail motor fuel sites during 2006 and sold a combined total at all four sites of 100,000 gallons of diesel fuel, of which 55,000 gallons was biodiesel blended fuel containing a minimum percentage of 2 percent by volume of biodiesel. Because 50 percent or more of the diesel fuel sold was biodiesel blended fuel, the taxpayer may claim the biodiesel blended fuel tax credit totaling $1,650, which is 55,000 gallons multiplied by three cents.
Example:  A taxpayer operated two retail motor fuel sites during 2006, and each site sold 40,000 gallons of diesel fuel. One site sold 25,000 gallons of biodiesel blended fuel, and the other site sold 10,000 gallons of biodiesel blended fuel. The taxpayer would not be eligible for the biodiesel blended fuel tax credit because only 35,000 gallons of the total 80,000 gallons, or 43.75 percent of the total diesel fuel gallons sold, was biodiesel blended fuel. The 50 percent requirement is based on the aggregate number of diesel fuel gallons sold by the taxpayer, and the fact that one retail motor fuel site met the 50 percent requirement does not allow the taxpayer to claim the biodiesel blended fuel tax credit for the 2006 tax year. If the facts in this example had occurred during the 2009 tax year, the taxpayer could claim a biodiesel blended fuel tax credit totaling $750, which is 25,000 gallons multiplied by three cents, since one of the retail motor fuel sites met the 50 percent biodiesel blended fuel requirement.
	 52.31(1) Fiscal year filers. For taxpayers whose tax year is not on a calendar-year basis and whose tax year ends before December 31, 2006, the taxpayer may compute the tax credit on the gallons of biodiesel blended fuel sold during the period from January 1, 2006, through the end of the tax year, provided that 50 percent of all diesel fuel sold during that period was biodiesel blended fuel. Because the tax credit is repealed on January 1, 2012, a taxpayer whose tax year ends prior to December 31, 2011, may continue to claim the tax credit in the following tax year for any biodiesel blended fuel sold through December 31, 2011, provided that 50 percent of diesel fuel sold at qualifying retail motor fuel sites during that period was biodiesel blended fuel.
Example:  A taxpayer who operates one retail motor fuel site has a fiscal year ending April 30, 2006. The taxpayer sold 60,000 gallons of diesel fuel for the period from May 1, 2005, through April 30, 2006, of which 28,000 gallons was biodiesel blended fuel. However, for the period from January 1, 2006, through April 30, 2006, the taxpayer sold 20,000 gallons of diesel fuel, of which 12,000 gallons was biodiesel blended fuel. The taxpayer is entitled to claim the biodiesel blended fuel tax credit of $360 (12,000 gallons times 3 cents) on the taxpayer’s Iowa income tax return for the period ending April 30, 2006, since more than 50 percent of all diesel fuel sold during the period from January 1, 2006, through April 30, 2006, was biodiesel blended fuel.
Example:  A taxpayer who operates one retail motor fuel site has a fiscal year ending June 30, 2006. The taxpayer sold 80,000 gallons of diesel fuel for the period from July 1, 2005, through June 30, 2006, of which 42,000 gallons was biodiesel blended fuel. However, for the period from January 1, 2006, through June 30, 2006, the taxpayer sold 40,000 gallons of diesel fuel, of which 19,000 gallons was biodiesel blended fuel. The taxpayer is not entitled to claim the biodiesel blended fuel tax credit on the taxpayer’s Iowa income tax return for the period ending June 30, 2006, since less than 50 percent of all diesel fuel sold during the period from January 1, 2006, through June 30, 2006, was biodiesel blended fuel, even though more than 50 percent of all diesel fuel sold during the period from July 1, 2005, through June 30, 2006, was biodiesel blended fuel.
Example:  A taxpayer who operates one retail motor fuel site has a fiscal year ending February 28, 2012. The taxpayer sold 100,000 gallons of diesel fuel for the period from March 1, 2011, through February 28, 2012, of which 60,000 gallons was biodiesel blended fuel. For the period from March 1, 2011, through December 31, 2011, the taxpayer sold 85,000 gallons of diesel fuel, of which 50,000 gallons was biodiesel fuel. The taxpayer is entitled to claim the biodiesel blended fuel tax credit of $1,500 (50,000 gallons times 3 cents) on the taxpayer’s Iowa income tax return for the period ending February 12, 2012, since the credit is computed only on gallons sold through December 31, 2011.
	 52.31(2) Allocation of credit to owners of a business entity. If a taxpayer claiming the biodiesel blended fuel tax credit is a partnership, limited liability company, S corporation, or an estate or trust electing to have the income taxed directly to the individual, an individual may claim the credit. The amount claimed by an individual must be based on the individual’s pro-rata share of the individual’s earnings of the partnership, limited liability company, S corporation, or estate or trust.
This rule is intended to implement Iowa Code Supplement section 422.33 as amended by 2008 Iowa Acts, House File 2689, section 33.
