Common questions
What is the Alberta IFTA diesel tax rate for the 4th quarter 2026?
C$0.0000 per litre ($0.0000 per U.S. gallon), for fuel used October to December 2026. That is down C$0.1300 a litre from Q3 2026.
What Alberta rate goes on my 3rd quarter 2026 return?
C$0.1300 per litre ($0.3519 per U.S. gallon) for diesel. That return covers July to September 2026 and is due October 31, 2026.
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.
