Mayor Katie Wilson Proposes Doubling Seattle Sales Tax for Bus Service

Seattle Mayor Katie Wilson announced a proposal Tuesday to double the city’s sales tax dedicated to bus transit, seeking a 10-year renewal of the Seattle Transit Measure. Speaking at a City Hall news conference, Wilson outlined a plan to increase the current 0.15% sales tax to 0.3%, or 30 cents per $100 purchase. The measure, which requires approval from the City Council before heading to voters this November, aims to generate an average of $138 million annually. These funds would support approximately 765 daily bus trips beyond what King County Metro provides independently, focusing heavily on all-week frequency and service in lower-income neighborhoods. The proposal marks a shift from the current six-year cycle to a decade-long commitment, signaling Wilson’s long-term strategy to reduce car dependency. If passed, the measure would increase the total state and local sales tax rate in Seattle from 10.55% to 10.7%. The move comes as the city grapples with a $35 billion funding gap in regional light rail expansions and a slow but steady recovery in post-pandemic bus ridership. Mayor Wilson, a former transit advocate, identified the tax as a tool for making the city more affordable by allowing residents to live without the high costs of vehicle ownership.

Mayor Wilson Targets High-Frequency Service and Low-Income Affordability

The core of the mayor’s proposal involves a significant expansion of transit capacity, specifically targeting 280,000 annual bus trips. According to the SDOT Blog, this represents an increase of 100,000 trips compared to the current transit measure. The funding is intended to ensure that transit remains a viable option for those who do not work traditional 9-to-5 schedules. By prioritizing off-peak, night, and weekend service, the city hopes to capture the segment of the population where ridership has grown most quickly since 2020. Angela Brady, acting director of the Seattle Department of Transportation, noted that frequent all-hours service is a primary driver of affordability, particularly for residents in neighborhoods like White Center, Georgetown, and Beacon Hill.

A second major pillar of the plan is the expansion of the low-income ORCA fare card program. The proposal aims to double the number of free transit passes, providing roughly 22,000 cards to eligible residents. These subsidies are part of a broader $96.1 million annual allocation toward operations. According to The Seattle Times, the plan also includes $23.4 million per year to maintain the city’s two streetcar lines and $3.5 million for physical street improvements. These capital investments include modifications at traffic pinch points to prevent buses from becoming stuck in congestions, such as the planned bus-only lane on Denny Way designed to improve the reliability of Route 8.

Total Revenue and the Financial Cost to Seattle Households

The financial scale of the new Seattle Transit Measure reflects a more aggressive fiscal approach than its predecessors. By doubling the tax rate and extending the duration to 10 years, the city expects to raise nearly $1.4 billion over the life of the measure. For the average two-person household earning approximately $124,000 a year, city staff estimate the annual tax burden will be $58, up from the current $29. This estimate, reported by The Seattle Times, seeks to frame the increase as a modest cost relative to the potential savings of reduced gasoline and parking expenditures. However, the reliance on sales tax remains a point of contention in a state already criticized for having a regressive tax structure.

Historically, Seattle transit measures included a mix of revenue sources, such as car-tab fees. In 2014, voters approved a $60 vehicle license fee alongside a smaller sales tax. Mayor Wilson explained her decision to omit car-tab fees from the 2026 ballot measure by citing the potential for organized political opposition. While acknowledging that sales taxes are not a perfect economic tool, the administration appears to have calculated that a sales tax increase is more likely to pass than a fee specifically targeting car owners. This strategic choice places the burden of transit funding on all consumers in the city, rather than strictly on those who drive, reflecting Wilson’s background as a socialist campaigner focused on broad-based public services.

Critics Question Fiscal Efficiency Amid Regional Funding Shortfalls

Despite the landslide 80% support for the previous transit measure in 2020, the new proposal faces scrutiny regarding the efficiency of the regional transit system. Charles Prestrud of the Washington Policy Center argued that the tax increase could negatively impact social equity, pointing out that 81% of low-income workers still rely on driving or carpooling. Prestrud characterized the continued infusion of cash into regional projects like Sound Transit 3 as a "black hole," where taxpayers may not see tangible benefits for decades. His comments, reported by The Seattle Times, highlight a divide between urban planners who prioritize transit-oriented development and analysts who worry about the rising cost of living in the Puget Sound area.

The debate is further complicated by the current state of King County Metro’s ridership and fare recovery. Data from March 2026 shows average weekday ridership at 274,000, which is a third lower than the 2019 peak of 410,000. Critics note that while ridership is recovering, fares currently cover less than 10% of operating costs. Additionally, King County Metro reported no specific routes plagued by overcrowding last year, though reliability and lateness remain persistent issues. The mayor’s proposal seeks to address these reliability gaps by funding more frequent runs, even if buses are not yet reaching capacity, under the theory that frequency itself stimulates demand and supports long-term growth.

Support for Sound Transit and Streetcar Integration

A distinctive feature of Wilson’s proposal is the inclusion of $6.1 million annually to support Sound Transit 3 expansions. This funding is intended to help the city manage permitting and accelerate the construction of projects like the Graham Street Station in Rainier Valley. By using city-level sales tax to support a regional transit agency, Wilson is attempting to mitigate a $35 billion shortfall that threatens the future of projects such as the Ballard light rail line. As noted in the SDOT Blog, this integration ensures that the city’s bus network and streetcars work in tandem with the growing light rail spine.

The streetcar system, which has faced historical criticism for low ridership and high operating costs, receives a lifeline in this measure. The $23.4 million annual allocation for the First Hill and South Lake Union lines suggests the administration views these as essential components of the urban core’s transit grid rather than optional amenities. This specific carve-out for streetcars indicates a commitment to diverse transit modes, even as the bulk of the funding remains focused on the more flexible bus network. By securing this funding through a 10-year ballot measure, the city provides a level of financial certainty for these services that annual budget cycles often lack, allowing for more stable long-term planning.

Analyzing the Economic Shift from 2020 to 2026

When comparing the 2020 measure to the current proposal, several shifts in Seattle’s economic and political environment become clear. In 2020, the city was in the early stages of the pandemic, and the measure was a six-year "bridge" to maintain existing service levels. The 2026 proposal is significantly more ambitious, doubling the rate and nearly doubling the duration. This shift suggests that the Wilson administration believes the public’s appetite for transit investment has not waned despite the rise of remote work and the resulting changes in commuting patterns. While The Seattle Times notes that ridership remains below 2019 levels, the mayor is pivoting toward a "service-first" model that treats transit as a basic utility rather than just a peak-hour commute tool.

This approach carries risks. If inflation continues to pressure household budgets, a sales tax increase to 10.7% may face more resistance than the 2020 vote. Furthermore, the decision to use city funds to "bail out" regional Sound Transit shortfalls could be perceived by some voters as Seattle taking on a disproportionate share of a regional burden. However, Wilson’s history as a co-founder of the Transit Riders Union gives her a base of support that is deeply invested in these specific outcomes. The move to link transit frequency to affordability—by framing it as a way for families to go "car-light"—is a targeted message intended to resonate with younger, urban voters who are increasingly priced out of the city’s housing and transportation markets.

Next Steps for the Seattle Transit Measure Ballot Race

The proposal’s journey toward the November 3 ballot begins with the Seattle City Council. The council must review and approve the language of the measure before it can be formally submitted to the King County Elections office. Given the current composition of the council and the mayor’s political alignment, the measure is expected to receive a favorable reception, though there may be debate regarding the specific allocation of funds between bus service, streetcars, and light rail support. The SDOT Blog indicates that if passed, the new tax would not take effect until 2027, providing a transition period as the current 0.15% tax expires.

Voters can expect a vigorous campaign over the summer and fall. Advocacy groups including the Transit Riders Union and various environmental organizations are likely to mobilize in support, emphasizing the measure's role in reducing carbon emissions. Conversely, fiscal watchdog groups may use the opportunity to criticize the rising cost of living in Seattle. The outcome will serve as a significant test of Mayor Wilson's mandate and the city's willingness to continue taxing itself at higher rates to sustain its vision of a transit-first metropolitan area. With the Puget Sound region already spending more on transit than most other U.S. metro areas, the November vote will determine whether Seattle remains an outlier in its commitment to high-frequency public transportation.
