Tracking Miles in Each State

It is the responsibility of drivers and fleet managers to record the amount of fuel consumed in each state/jurisdiction. Drivers also must record the readings on their odometer when they cross each state/jurisdiction. You can use fleet management softwares to make these tasks easier.

Calculating Fuel Purchase

Drivers are also responsible for calculating the total amount of fuel used in each state/jurisdiction.

An important point note is that the drivers must save the original receipts or invoices to prove that payment of the fuel taxes has been done. Following are the detail that the documents are required to have:

  • Date of purchase
  • Name and location of the fuel seller
  • What type of fuel was purchased
  • Vehicle plate number
  • Price per gallon
  • Drivers name

Calculating The Fuel Consumed

After you have the mileage in each state and the amount of fuel purchased in each state/purchased, it is easy to calculate the amount of fuel used in each state by using the following formula

Total Number of Miles Driven In a State ÷ Total Amount of Fuel Purchased = Overall Fuel Mileage

To calculate the amount of fuel your fleet consumed, use the following formula

Total Number of Miles Driver In a State ÷ Overall Fuel Mileage = Total Amount of Fuel Consumed in the State

Calculating Taxes Owed to Each State

The amount of fuel purchased in each state/jurisdiction is required to calculate the amount owed to each state.

Finally you can use the following formula to calculate the exact tax amount you owe each state

Fuel Tax Required in State X – Fuel Tax Paid in State X = Fuel Tax Owed to State X

Originally drivers used to record and track the miles and fuel purchase manually but now the drivers can use the tax reporting sheets from the Owner-Operator Independent Drivers Association (OOIDA) to track the miles and fuel purchase and also they can turn to cloud based services and fleet management software to aid them in the same.

Calculating IFTA taxes can be tiring and mentally exhausting but in this age of scientific advancements it is possible to record your mileage in each state and also to record the amount of fuel purchased and used in every state/jurisdiction by using fleet management software.

There are a lot of GPS vehicle tracker that come along with fleet management software. By using this, you can easily do your calculations accurately as it erases the possibilities of human error in calculations.

When the fleet tracking data is combined with the tax software can help you calculate you IFTA taxes and make sure you’re paying only what you owe.
