Learn moreNo state income tax -- and the statewide capital gains excise tax nuance
Washington has no state personal income tax. As documented in full in washington.js, this coexists with a real, current, legally upheld capital gains excise tax on high earners (7% on long-term gains above an inflation-indexed threshold, 9.9% above $1 million), applying to Renton residents the same as any other Washington resident.
Renton's 10.5% combined sales tax
Renton's combined 2026 sales tax rate is 10.5% -- among the higher combined rates in this Washington build, comparable to Tacoma's, and higher than Kent's or Federal Way's 10.4%.
King County's property tax structure
Renton sits in King County and shares the countywide average effective property tax rate of approximately 0.83% documented in the companion bellevue-wa.js and redmond-wa.js records -- the highest of Washington's 39 counties, reflecting the county's elevated home values.
