  • Example 1: A taxpayer purchases 15.365 gallons of gasoline on October 25, 2021, for off road usage. The motor fuel tax rate for this time period is $0.195 per gallon. The taxpayer will multiply 15.265 by $0.195 (15.265 x $0.195). The taxpayer has paid $2.98 in motor fuel tax and may request a refund of that amount using Form 4923.
  • Example 2: A taxpayer purchases 21.325 gallons of gasoline on October 25, 2021, for use in their vehicle on the highway and that use meets the requirements to request a refund of the additional tax paid. The motor fuel tax rate for this time period is $0.195 per gallon, but only $0.025 of that is the increased rate on which a refund may be requested. The taxpayer will multiply 21.325 by $0.025 (21.325 x $0.025). The taxpayer has paid $0.53 in increased motor fuel tax and may request a refund of that amount using Form 4923-H.

Fuel receipts that don’t indicate gallons purchased require the refund claimant to record the gallons amount on the receipt in order to claim the appropriate number of gallons for refund.

No, the eligible purchaser discounts remain the same regardless of the tax rate. Section 142.848 RSMo, states in part that remittances by an eligible purchaser of tax due the supplier are paid on the basis of ninety-seven percent for gasoline products and ninety-eight percent for diesel products.

For example, the motor fuel tax rate is $0.195 per gallon of gasoline and clear diesel. An eligible purchaser would be taxed by their supplier at a rate of $0.18915 per gallon of gasoline and $0.1911 per gallon of clear diesel.
