WA State’s ‘Automatic’ Gas Tax Hike Began July 1st., And Will Never End?

Never before has WA state had an automatic gas tax, which will increase every year unless...

   The Tax Went Up July 1st. Again

Gas taxes are required by the State Constitution to only be used for road and related infrastructure projects. It's one of the few revenue sources that can't be raided by legislators for other purposes.

Over the years the gas tax has not matched infrastructure and road needs, due largely to more fuel-efficient vehicles, and drivers adapting to rising prices with more streamlined condensed travel.

Signed into law by Governor Ferguson in 2025, it went into effect July 1st. Under the guise of 'inflationary increases,' the tax will now go up 2.2 percent annually, into perpetuity.  The tax has no expiration date.

 The Increase is 'Only' 1.1 Cents Per Gallon, But...

As the Washington Policy Center revealed, it's the first such gas tax of its king, and likely the first in the US.   According to the Center:

"State gas taxes were previously increased by $.06 per gallon in 2025, bringing the state total to 55.4 cents per gallon. That is in addition to the federal taxes of 18.4 cents per gallon and the fees added by the State’s Climate Commitment Act that tack on about 50 cents per gallon. As a result, Washington residents pay among the highest gas prices in the country, frequently more than a dollar per gallon above other states."

The Center points out this automatic process takes pressure off the Democrat-controlled legislature to act on tax relief for citizens, and it bluntly disregards citizens' rights to voice their opinions and determine laws by removing them from the process.

 Why Is Gas Tax Not Filling the Void?

Over the next biennium, the tax revenue is expected to be at least $435 million short of expectations. Experts say declining fuel consumption and to a smaller degree, the implementation of electric vehicles has had an effect.

The tax could be disposed of, but it would take a majority of sensible legislators which is not currently the state in Olympia.  Democrats control the purse strings and they show no appetite for giving tax relief to consumers.

The Department of Transportation has experimented with pay-by-the mile programs, but they are riddled with questions about driver privacy, issues with reporting, and how would the state find ways to only charge drivers for state-maintained roads.
