Calculating Fuel Tax Reports

  • TOTAL MILES – Enter the total miles traveled in each jurisdiction for this fuel type.
  • TOTAL TAXABLE MILES – Enter the total taxable miles in each jurisdiction minus fuel trip permit miles. Fuel trip permit miles are not considered taxable miles in any jurisdiction. Toll miles and off-highway miles are not taxable mile in some jurisdictions. Contact each jurisdiction for information on these exceptions. If you forget to write down taxable miles, total miles will be used as taxable miles. NOTE:  Total taxable miles cannot be greater than total miles
  • TAXABLE GALLONS CONSUMED – Divide total taxable miles by the MPG factor. Round to the nearest whole gallon.
  • TAX PAID GALLON PURCHASES – Enter gallons purchased from fuel receipts for all qualified motor vehicles.  Example: Total all fuel receipts from Missouri. If receipts total 1,000 gallons then Missouri will be 1,000. Total all receipts for Illinois. If receipts total 50 gallons then the total gallons for Illinois will be 50. Do this for each jurisdiction in which you purchased fuel.
  • BULK STORAGE – When using bulk storage, report only tax paid gallons removed for use in your qualified motor vehicles. Fuel remaining in storage cannot be claimed until it is use.
  • NET TAXABLE GALLONS – The difference between taxable gallons consumer and tax paid gallons purchased  If taxable gallons consumed is greater than tax paid gallons, subtract tax paid gallons  from taxable gallons consumed and enter the taxable gallons under net taxable gallons. This is a tax due. If tax paid gallons are greater than taxable gallons consumed, subtract taxable gallons consumed from tax paid gallons and enter the taxable gallons in net taxable gallons. This is a credit earned.

The surcharge line for IN, KY, & VA will be the same as taxable gallons consumed. No credits for fuel purchase are given when computing for surcharges.

  • TAX RATE – Enter the tax rate for each jurisdiction for the fuel type reported on this return. The tax rate for each jurisdiction’s fuel types should be included with the quarterly tax report, and are subject to change each quarter.
  • TAX DUE/CREDIT EARNED – Calculate the tax due or credit earned for each jurisdiction by multiplying net taxable gallons by tax rate. This will be the tax due or credit earned for each jurisdiction.
  • INTEREST DUE – For late or amended returns, interest is computed on the tax due from the due date of the return until payment is received. Interest is computed at 1 percent per month.
  • TOTAL – Add amounts from tax due/credit and interest due (if applicable). This will be the tax due or credit earned for each jurisdiction.  This is the net result. Compute by adding positive numbers in Total column (tax due) and subtracting negative numbers in Total column (credit earned). The net result will be either positive (tax due) or negative (credit earned).
  • Enter the net results, of tax due or credit earned.   Returns not filed by the due date are considered late and any taxes due are delinquent. A penalty of $50.00 or 10 percent of net tax liability, whichever is greater, will be assessed on late filed returns, failure to file, or for underpayment of tax due. If the net tax liability is zero or a credit, the late filing penalty is $50.00.
  • TOTAL REMITTANCE – This is the total of all taxes, interest (if applicable), and penalty (if applicable).
