Frequently asked questions
Why does the matrix change every quarter?
States index fuel taxes to inflation or fuel prices and Canadian rates float with exchange rates, so IFTA Inc. republishes the matrix quarterly. Filing with last quarter's rates is a common rejection reason.
Which fuel column is this?
Special diesel — the column that applies to Class-8 trucks. Gasoline, propane and LNG rates differ; this site currently covers diesel fleets.
