Editor’s note: Earlier posts in this series used the figures $63 and $41 million in referring to the size of the loophole. The $59 million figure used below draws on newly available calculations from the WA OFM.

Facing a Supreme Court order to fund public education, Governor Inslee and others have combed through the state tax code in search of outdated and perverse tax loopholes. Perhaps none of them is more bizarre than the “extracted fuel use tax exemption”—a purely accidental giveaway to oil refineries that costs the state $59 million each budget cycle.

Oil companies are stalling to prevent paying the same taxes everyone else does, even though the cost of closing the loophole would represent only a tiny fraction—less than 1 percent—of their overall costs.


Closing the loophole makes sense, as a means to both fund public education and inject a modicum of fairness into the state tax code. What’s more, the tax benefit, which dates to 1949, was never intended for oil companies in the first place. In fact, the law was written for sawmills at a time when there were no oil refineries in the state.

    Thanks to Thomas Kerrigan for supporting a sustainable Cascadia.

  • It was only later that refiners moved into Washington and exploited the tax code’s loose language so thoroughly that they now claim 98 percent of the benefit.


    Fortunately, there’s a bill in the legislature that would close the loophole and redirect the money to classrooms. I’ll be testifying on it before the House Finance committee on February 6 at 8 am.
