How IFTA Tax Calculation Works
The International Fuel Tax Agreement (IFTA) requires carriers operating in multiple jurisdictions to pay fuel taxes based on miles driven in each state, not where fuel was purchased.
The formula:
- Calculate Fleet MPG = Total Miles / Total Gallons
- Taxable Gallons per State = State Miles / Fleet MPG
- Tax Due per State = Taxable Gallons x State Tax Rate
- Tax Paid per State = Gallons Purchased in State x State Tax Rate
- Net Tax = Tax Due - Tax Paid (positive = you owe, negative = credit)
Our calculator automates all of this with current tax rates for all IFTA jurisdictions.
