King County shoppers will pay a little more at the register starting January 1, 2027, after the Metropolitan King County Council voted 6-3 to raise the county's sales tax by 0.01% to pay for emergency shelter for homeless children and families. The council skipped a public referendum entirely, relying on new authority from Olympia that lets local lawmakers approve modest tax hikes for housing and behavioral health projects without sending the question to voters.
The increase amounts to roughly a penny for every $100 spent, and Councilmember Claudia Balducci said it would cost the average taxpayer about $4 a year, according to KOMO News. The county estimates the tax will generate about $10 million annually, revenue that will flow into the Housing and Community Development fund administered by the King County Department of Community and Human Services, according to Seattle Red.
Council members cited stark numbers behind the push: King County has 967 youth experiencing homelessness but only 187 shelter beds available, per figures the council itself presented. Bill sponsor Jorge Barón said he believed the tax increase could meaningfully affect the broader homelessness crisis, and Councilmember Rod Dembowski said the crisis label is warranted in this case, both according to the same KOMO report. Barón added he was unwilling to wait for others to act, though he said he would welcome later action by the state or the county executive to bring more young people and families indoors.
Why Lawmakers Skipped the Ballot
The 2026 state legislation that cleared the way for the increase allows county and city councils to pass small sales tax hikes for affordable housing, behavioral health facilities, and similar projects without a public vote. The Metropolitan King County Council's approval came October 6, with Councilmembers Reagan Dunn, Sarah Perry, and Pete von Reichbauer casting the dissenting votes, the vote breakdown reported by The Daily Chronicle.
Had the county instead placed the measure on the February 2027 ballot, officials estimated the election could have cost between $2.1 million and $3.9 million if it were the only issue on that ballot, per KOMO's reporting. The sales tax itself is set to expire after three years, at which point the county council will reassess next steps, the outlet noted.
Dunn voted no, telling KOMO he did not think the increase would achieve its intended impact and arguing that King County already carries the nation's highest sales tax, which this hike will push even higher. The Daily Chronicle reported that Dunn's opposition also pointed to compounding financial burdens on residents alongside recent county audits. The statute includes a safeguard against double taxation: if individual cities within King County later adopt an identical local tax for the same safety-net services, their municipal collections will be credited against the county's share, per the Daily Chronicle.
Seattle's Rate Could Climb Past 10.8%
Once the county increase takes effect, Seattle's total retail sales tax rate will reach 10.56%, up from its current 10.55%, placing it among the highest municipal rates in the nation, according to The Center Square. Other cities within King County could see rates reach as high as 10.55% as well, the outlet reported. This marks the second councilmanic sales tax increase the county council has passed in 2026, following a separate 0.1% hike approved in June for countywide road repairs, The Center Square noted.
Seattle voters still have a say in a related measure come November: Proposition 1 would double the city's transit-dedicated sales tax from 0.15% to 0.30% to fund expanded bus service across major corridors. If approved alongside the county's shelter tax, the combined effect would lift Seattle's overall sales tax rate to 10.81% in 2027, according to PubliCola.
Shelter Funding Meets a Growing Crisis
The tax arrives as King County's homelessness numbers keep climbing. A 2026 regional Point-in-Time count found homelessness in the county rose 9% between 2024 and 2026, reaching 18,365 people, with about 64% living unsheltered in vehicles, parks, and other outdoor locations, as Hoodline previously reported. King County Executive Girmay Zahilay anticipated the council's vote by announcing plans in September for more than 500 units of affordable housing, tiny home villages, and family emergency shelter projects across the region, per the Daily Chronicle.
The tax vote also lands amid a broader shake-up in how the region manages homelessness dollars. Zahilay and Seattle Mayor Katie Wilson announced in August that nearly $160 million in human services contracts would move from the King County Regional Homelessness Authority back under direct city and county management by January 2027. On the same day the council passed the sales tax, it also appointed a new Inspector General tasked with rooting out waste or fraud in county-funded human services programs, Seattle Red reported, a move that speaks directly to the skepticism voiced by council members who opposed the tax.
Exactly how the new revenue will be divided among shelter providers, rental assistance, and other programs remains unresolved. According to KOMO, King County will determine those specific spending details during upcoming county budget deliberations, with the council set to evaluate next steps when the three-year tax expires.
