King County leaders have approved a new 0.1% sales tax expected to generate approximately $100 million annually for road maintenance and transportation projects across the county, passing on a narrow 5-4 vote despite opposition from several Seattle leaders who say the distribution formula shortchanges the city.
For consumers, the tax increase translates to roughly $1 in additional cost on a $1,000 purchase. Supporters of the measure argue the funding is necessary to address growing transportation and road maintenance needs across King County’s cities and unincorporated areas, many of which have struggled to keep pace with ageing infrastructure and rising construction costs.
Critics, including the Seattle leaders who opposed the measure, argue that the current distribution formula could result in Seattle receiving less funding back than its taxpayers contribute into the system. They contend that the revenue should be allocated more equitably across the county’s cities rather than following a formula that may disproportionately benefit smaller jurisdictions relative to their tax contributions.
The dispute reflects a broader and recurring tension in King County governance over how regional tax revenue should be shared between Seattle, the county’s largest city and economic engine, and smaller surrounding municipalities that also rely on county-level funding for infrastructure projects.
