IFTA Net-Tax Estimator

Enter your quarterly totals to get a ballpark estimate, no account needed.

Estimate only, not a filed IFTA return

Quarter & fuel type

Fleet totals for the quarter

Include all miles driven (IFTA and non-IFTA) so fleet MPG is accurate.

All vehicles, all states/provinces

All qualifying fuel purchases

Miles per jurisdiction

Enter taxable miles only (miles driven on qualified roads in each IFTA jurisdiction). The optional tax-paid gallons column is for fuel you already paid tax on in that state.

This estimate uses the published IFTA rate matrix. It is not a filed return.
