How it works
How it works
Fleet miles per gallon is total miles divided by total gallons bought in all states. For each state, taxable gallons are the state's miles divided by fleet MPG, and net taxable gallons are taxable gallons minus the gallons you bought there. Multiply by that state's rate for the net tax, where a negative result is a credit. The rates in the boxes are invented examples. Take the current rates from the official IFTA source, and use the official return for filing.

FAQ
About this calculator
Are these real IFTA rates?
No. The rates are invented examples. Get current rates from the official IFTA source or your base jurisdiction.
Can I file with this?
No. It is a worksheet to help you check your numbers. File on the official return.
What if I have more than four states?
Use the trucking tracker workbook, which covers all jurisdictions, or run the calculator in groups and add the results.
Why is the net tax negative for some states?
You bought more fuel there than your miles there used, so it is a credit for that state.
Is anything saved?
No. The math runs in your browser and nothing you enter is sent to us.
