701—64.5 (452A) Tax reports—computations. Any person who receives motor fuel in the state of Iowa and any person licensed as a motor fuel distributor must file a monthly report showing the invoiced gallons of motor fuel received and the invoiced gallons subject to tax, and include therewith a remittance in the amount of tax due, if any. The report must be filed by anyone holding an uncanceled motor fuel distributor’s license or any person who had “received” motor fuel during the reporting period. The report must be filed by the last day of the month following the month covered by the report. If a licensed distributor received no fuel for any month, the monthly report must still be filed when due, or the distributor will be subject to a $10 penalty. (See Iowa Code section 452A.65.) The amount of tax due is computed as follows:
	  1. 	 ADD: The total number of invoiced gallons received (include all fuel received and subsequently sold for export or exported out of state, sold to a licensed Iowa urban transit system, sold to the federal government, and sold for producing ethanol blended gasoline).
	  2. 	 DEDUCT: The number of invoiced gallons sold for export or exported out of state, sold to a licensed Iowa urban transit system, sold to the state, any of its agencies, or to any political subdivision of the state (see subrule 64.3(4)), sold to the federal government and used by the distributor for producing ethanol blended gasoline (these deductions will not be allowed without the appropriate supporting documents, i.e., export schedules, exemption certificates, or statements). (See rule 64.4(452A) for the procedure for deducting motor fuel used to produce ethanol blended gasoline.)
	  3. 	 DEDUCT: For periods prior to September 1, 1981. Three percent of the first 300,000 invoiced gallons remaining after the deduction in 64.5“2” and 1¼ percent of the invoiced gallons in excess of 300,000 after the deduction in 64.5“2.”
	  4. 	 DEDUCT: For periods after August 31, 1981, 2 percent of the first 300,000 invoiced gallons remaining after the deduction in 64.5“2” and 1 percent of the invoiced gallons in excess of 300,000 after the deduction in 64.5“2.”
	  5. 	 MULTIPLY: The net taxable gallons by the appropriate tax rate. This results in the tax liability.
	  6. 	 DEDUCT: Any outstanding credit. This results in the tax due.
A remittance in the amount of the tax due should accompany the monthly report. The appropriate penalty, interest, and application of penalty, interest, and tax are discussed in rules 701—63.8(452A), 63.10(452A), and 63.11(452A).
These are only the computational factors in determining the taxpayer’s liability, and should not be considered an enumeration or limitation of the information required in the report to be filed.
This rule is intended to implement Iowa Code sections 452A.3, 452A.8 and 452A.9.
