Staying compliant with the IFTA reporting requirements is one of the main responsibilities of anyone who runs a trucking business. To comply with IFTA reporting every quarter, it’s important for trucking businesses to know about the IFTA tax rates for each jurisdiction and how it is calculated.

This article discusses in detail the IFTA tax rate and the calculations involved in determining it.

What is the Purpose of IFTA?

The IFTA (International Fuel Tax Agreement) is an agreement between the 48 contiguous states and 10 Canadian provinces regarding the fuel usage of commercial motor vehicles and its applicable taxes.

IFTA facilitates the reporting of fuel usage by commercial motor vehicles that operate in more than one jurisdiction. These fuel tax reports are used by base jurisdictions to collect net fuel taxes and redistribute the taxes to other states.

Who Should compliant IFTA Reporting?

IFTA reporting must be completed by qualified motor vehicles which meet any one of
the following criteria:

  • Gross Vehicle Weight (GVW) 26,000 pounds or more
  • Have three or more axles
  • Trucks involved in transporting commercial goods across state lines or the
    U.S./Canadian border.

Drivers of these vehicles should report their fuel usage to their base jurisdiction (the state in which the vehicles are registered or maintained).

What is the IFTA Tax Rate and how is it calculated?

The IFTA tax rate is the amount of tax deducted per gallon of fuel consumed within the borders of each jurisdiction. The tax rate varies for each fuel type.

Each member jurisdiction of IFTA is allowed to set its own tax rate. These tax rates are subject to change frequently.

What are the Calculations Involved in Determining the IFTA Taxes?

To figure out the quarterly IFTA fuel taxes, you need to make sure that you have the
following information:

  • Overall Fuel Mileage

    The overall vehicle mileage can be calculated by using the below formula:
    Fuel Mileage = Total Miles traveled / Total Fuel Purchased

  • Total Miles Traveled in each state
  • Fuel Purchased in each state (in Gallons)
  • Fuel Consumed in each state (in Gallons)

    The below formula can be used to calculate the amount of fuel consumed in each state:
    Fuel consumed in State X = Total Miles traveled in State X / Overall
    Fuel Mileage

  • Fuel Tax rates of each state
  • Fuel Tax Required in each state

    Use the below formula to figure out the amount of fuel taxes required by each state:
    Fuel Tax Required in State X = Fuel Consumed in that State x Fuel Tax Rate of that State

  • Fuel Taxes Paid in each state:

    The amount of fuel taxes paid in each state is calculated using the below formula:
    Fuel Tax Paid in State X = Fuel Purchased in that State x Fuel Tax Rate of
    that State

Based on above data, you can find out the fuel taxes owed to each state using the below formula:


Fuel taxes calculation:
Fuel taxes owed to State X = Fuel taxes required in that State – Fuel taxes paid in that State
