Common questions
Where do these IFTA rates come from?
They are copied from IFTA, Inc.'s fuel tax rate matrix (iftach.org), the official list every member state and province reports its rates to. We check it every day and update these pages when it changes. The 4th quarter 2026 matrix is not final until December 4, 2026, so a rate can still change.
Which rates do I use for my 3rd quarter 2026 IFTA return?
The 3rd quarter 2026 rates, for fuel used in that quarter, even if you file later. That return is due October 31, 2026. Rates for 4th quarter 2026 apply to miles you drive now and go on the return due January 31, 2027.
What is a surcharge line?
Some states (for example Kentucky and Virginia) add a separate surcharge on fuel used in their state. It is listed as its own line on the IFTA matrix and on the return. The diesel totals on these pages add the surcharge to the base rate.
Why are Canadian rates shown per litre and in two currencies?
IFTA lists every rate both in U.S. dollars per U.S. gallon and in Canadian dollars per litre, using one exchange rate per quarter. A U.S.-based carrier files in gallons and U.S. dollars; a Canadian-based carrier files in litres and Canadian dollars.
Do I owe tax twice if I buy fuel in one state and drive in another?
No. You owe each state tax on the fuel you burned there (miles there ÷ your fleet MPG × that state's rate). The tax you already paid at the pump is credited. The IFTA return adds it up: you pay the states you under-paid and get credit from the ones you over-paid.
