If you are responsible for the payment of IFTA fuel taxes and/or receive IFTA fuel tax refunds, pump price should not be the sole determining factor as to where to buy fuel. These documents list average fuel prices by state or province, net of refundable taxes. They can assist you in determining where to buy fuel to minimize your overall fuel costs and taxes.
If you download the Excel document, you should enter the actual exchange rate at which you can purchase money and update the pump price in each jurisdiction to account for any discounts you receive from your suppliers.
As you travel, purchase most of your fuel in jurisdictions with the best rankings. Depending where you travel, this may not always be possible - at least purchase minimal fuel in the jurisdictions with the lowest rankings.
These files are updated every Friday morning with the average fuel prices from the previous day.
