2026-Q3Official IFTA, Inc. figures.
No rate listed IFTA, Inc.'s table gives no diesel rate for Oregon
Oregon doesn't list a fuel tax rate with IFTA. It taxes heavy trucks by weight and distance instead, through its Weight-Mile Tax Program, and carriers enrolled in that program buy fuel without paying Oregon fuel tax. Source: Oregon Department of Transportation, Motor Carrier recordkeeping (read 2026-10-22).
No separate fuel surcharge here — the rate above is the whole story.
