Seattle Mayor Katie Wilson has proposed doubling a sales tax that funds transit service in Seattle, known as the Seattle Transit Measure, to 0.3 percent, up from the 0.15 percent tax that expires this year. The proposal would raise around $138 million over the next ten years to pay for bus service, service on the city’s two streetcars, and transit passes for low-income riders, among other programs.
The Seattle Transit Measure, originally known as the Seattle Transportation Benefit District, supplements bus service provided by King County Metro by adding service hours in Seattle. The transit measure came out of a failed attempt 2014; in 2020, a proposal to increase the tax from 0.1 percent to 0.15 percent passed with more than 80 percent of the vote.
The extra money would fund 280,000 bus service hours a year on top of Metro’s regular service, Seattle Department of Transportation director Angela Brady said during a press conference on Tuesday. According to SDOT’s most recent annual report on the measure, the tax paid for 143,000 bus hours in 2024. The new funding would also pay for service on the existing streetcars that run between downtown and South Lake Union and Capitol Hill, and would provide free annual transit passes to everyone living in Seattle Housing Authority buildings, a new expansion of the ORCA Lift program for people making up to 200 percent of the federal poverty level.

Demonstrating how much costs have increased, the original, 0.1-percent 2014 transit measure expanded transit access by about 350,000 hours a year.
At Tuesday’s press conference, Wilson pitched her plan to expand transit hours as an urgent matter of affordability.
“When transit is frequent, reliable, and affordable, it does more than move people from one place to another—it gives people freedom,” Wilson said. “Transportation is one of the biggest costs in a household budget, and most of that cost comes from owning a car. Gas, insurance, repairs, parking, monthly payments, and maintenance all add up fast. So when we make our transit system better, we make it possible for more households to live car-free or car-light, and that could put hundreds or thousands of dollars back into a family’s budget. That is real affordability.”
If voters approve Wilson’s proposal, it will bring Seattle residents’ total sales tax burden close to 11 percent. Sales tax is the most regressive form of tax voters regularly pay, meaning that the poorer you are, the greater the percentage of your income you spend on the tax.
Asked about the seeming contradiction between her affordability pitch and the increasingly unaffordable sales tax burden, Wilson said it’s “unfortunate that we don’t have more progressive options for funding our transit system.” But, she said, “when we’re investing in public transit and making it possible for people to live car free or car light, when we’re investing in affordable fares, those are really direct supports that are creating affordability for the people in our communities that need it most.”
Under the state law that authorized the transportation benefit district, the city could also propose a vehicle license fee of up to $60—a tax on drivers that would directly fund the city’s primary alternative to driving. Asked why she didn’t do so, Wilson said she believed a license fee increase might prove too “controversial” to pass.
“I think we’ve seen car tab measures rouse more organized opposition, and I think we wanted to stick with something that we were really confident Seattle voters were going to be able to enthusiastically get on board with.”
A countywide measure to fund transit service with a 0.1 percent sales tax increase and a $60 vehicle license fee failed 55 to 45 percent. Since then, the city has relied on sales taxes alone to pay for additional transit service.
Wilson will have to move her proposal through the city council, starting with Rob Saka’s transportation committee. That committee will get an initial briefing on the proposal on Thursday. So far, Wilson has announced most big-ticket legislation without lining up council support or identifying council sponsors in advance. Saka, who was not present at Wilson’s press conference, did not immediately respond to a request for comment on the proposal, but we’ll update this post if we hear back.
