Notes
- * Oregon is not an IFTA diesel tax jurisdiction. Interstate trucks there pay Oregon’s weight-mile tax instead, filed separately with Oregon. Oregon miles still count toward your total miles and fleet MPG on the IFTA return.
- Surcharges (Kentucky, Virginia) are owed on taxable gallons used in that state on top of the diesel rate. They are not paid at the pump, so fuel bought there earns no surcharge credit.

- This quarter’s rate matrix can still be revised until December 4, 2026; check back before you file.
- Canadian provinces are not listed here.
Verify with your base jurisdiction before filing.
