Learn moreNo state personal income tax -- and the fuller picture
Washington has no state personal income tax. As documented in full in bellevue-wa.js, the state's capital gains excise tax (7% on WA-allocated long-term gains up to $1M, 9.9% above per the 2025 SB 5813 amendment) is real, current, legally settled law, applying to Bainbridge Island residents identically to King County residents elsewhere in this dataset.
Kitsap County's genuinely lower property tax rate
Kitsap County's average effective property tax rate ran 0.80% in 2026, with a median tax bill of $4,030 on a $505,700 home -- that median home value is a COUNTYWIDE figure well below Bainbridge Island's own much higher average, so an actual Bainbridge parcel's bill will run considerably above the county median even at the same 0.80% rate. Kitsap's rate runs genuinely below King County's 0.83% rate and Washington's own 0.84% statewide average.

Washington's state estate tax
