Fuel Tax refund may be available

Service stations, bulk plants, transporters and purchasers with fuel storage, such as farms, construction and trucking firms, may be eligible for a refund of tax when fuel has become contaminated. If clear and coloured fuels become accidentally mixed, the Fuel Tax Act may permit a refund of fuel tax paid or payable on the clear fuel portion. However, selling the mixed (contaminated) fuel or dispensing it to licensed motor vehicles may result in prosecution.

For more information about tax refunds on contaminated fuel, please review Ontario Tax Bulletin FT/GT 2-99 Tax Refunds: Bad debts and lost, destroyed, stolen or contaminated product.

What to do

To avoid having to pay fuel tax or a penalty related to the contaminated fuel, or liability for prosecution, dealers and others in possession of contaminated fuel must follow ministry guidelines.

If clear fuel is delivered into coloured fuel, or if coloured fuel is delivered into clear fuel, immediately do the following:

  1. If the fuel delivery is still in progress, stop loading or unloading the fuel to minimize the contamination;
  2. Quarantine and put the contaminated storage tank and pump or nozzle "out of service";
  3. Notify the Ministry of Finance (see contact information below)
  4. Record the plate number and vehicle description, driver's name and phone number for any licensed motor vehicles supplied with the contaminated fuel;
  5. Take a volume measure "dip reading" of the contaminated storage tank;
  6. If clear fuel storage is affected, quarantine or return the contaminated product to the supplier;
  7. If coloured fuel storage is affected, do not use until authorized to do so by the Ministry;
  8. If tank is refilled, take a further "dip reading" when completed;
  9. Obtain and keep the following information and documents for the ministry to collect at the time of inspection:
    1. Fuel delivery invoice/Bill of Lading;
    2. All dip readings including of the tank contents before the mistaken delivery;
    3. A record of the date and time of the delivery;
    4. A record of contaminated fuel sold or dispensed after the delivery;
    5. Details of motor vehicles fueled with contaminated fuel;
    6. Receipt or invoice for the tank pump out and, if applicable, disposal of the product;
    7. Fuel delivery invoice or Bill of Lading for the replacement fuel, if any.
