Washington gas tax and tolls to increase July 1
Washington's gas tax will increase by 6 cents per gallon, continuing to go up 2% each year to account for inflation, on July 1. Fox 13 reporter Nia Wong has more information.
OLYMPIA, Wash. - The bipartisan 6-cent gas tax hike in Washington goes into effect this week.
It is the first increase of its kind in about 10 years. Back in 2015, the legislature approved an 11.9-cent increase, which was fully phased in by 2016.
Republican and democratic lawmakers approved a 6-cent-per-gallon gas tax increase this year. While some released statements echoing cost of living concerns from residents, they also say it is something the state needs to keep highways in good shape.

Why the gas tax is going into effect in WA on July 1
What they're saying:
"I believe we have created a no-nonsense budget that will still keep our state’s transportation system moving forward. Raising fees and taxes is not something we take lightly, but we determined it was the only solution to address our state’s transportation challenges," said Sen. Curtis King (R-Yakima), the ranking Republican on the Senate Transportation Committee.
An overall drop in global wholesale gas prices will help offset the cost being reflected directly at the gas pump. The United States Energy Information Administration reports average gas prices are expected to decline by 11 cents by the end of the year.
Beginning in mid-2026, the gas tax will increase 2% annually, which lawmakers say will keep maintenance costs funded in line with inflation.
Additionally, there will be a 3-cent diesel tax in 2026, followed by another 3-cent increase in 2028. Lawmakers allocated 5% of these funds to go to local governments.
