King County Council Approves 0.1% Sales Tax to Fund Transportation Infrastructure

A new countywide sales tax aims to address road maintenance shortfalls, with funds allocated to local cities for transportation projects.

In a pivotal decision on June 12, 2026, the King County Transportation District Board voted 5-4 to implement a 0.1% countywide sales tax, projected to generate approximately $100 million annually. The primary objective of this tax is to address significant funding shortfalls in road maintenance, particularly in unincorporated areas of King County. Supervisor Steffanie Fain, representing Kent, Renton, Des Moines, SeaTac, Tukwila, and Normandy Park, cast a dissenting vote due to concerns over the tax's impact on affordability for working families. Despite her opposition to the sales tax, Supervisor Fain successfully advocated for the inclusion of the City Transportation Improvement Program (CTIP) in the final package. CTIP is designed to allocate approximately $12.5 million annually to King County's 39 cities, supporting local transportation infrastructure projects such as sidewalks, crossings, transit stops, bike facilities, and road improvements. The new sales tax is set to commence collection on January 1, 2027. While the tax aims to bolster the county's transportation network, it has faced opposition from Seattle leaders who express concerns about its impact on residents. Councilmember Claudia Balducci, chair of the transportation district board, emphasized the necessity of the measure to address decades of underfunding, noting that the county requires approximately $200 million annually to maintain roads in good condition. The implementation of this sales tax marks a significant development in King County's efforts to enhance its transportation infrastructure. The allocation of funds through CTIP ensures that cities across the county will receive direct support for local transportation projects, aiming to improve the daily commute and safety for residents. However, the debate over the tax underscores the ongoing tension between funding essential infrastructure and addressing affordability concerns for residents.
