Learn moreNo state personal income tax -- and the fuller picture
Washington has no state personal income tax. As documented in full in the companion bellevue-wa.js record, the state's 2021-enacted, 2023-upheld capital gains excise tax (7% on WA-allocated long-term gains up to $1M, 9.9% above that threshold per the 2025 SB 5813 amendment) is real, current, legally settled law -- directly relevant to Kirkland's tech-adjacent, equity-compensated workforce drawn partly by Google's two Kirkland campuses.
Kirkland's combined sales tax
Kirkland's minimum combined 2026 sales tax rate runs approximately 10.4% (Washington's 6.5% statewide base plus King County and local add-ons), consistent with the broader Eastside pattern.
King County's highest-in-Washington property tax rate
Kirkland shares King County's countywide average effective property tax rate of roughly 0.83% -- the highest of Washington's 39 counties -- with Bellevue and Redmond. A specific parcel's actual bill varies by taxing district; confirm directly with the King County Assessor.
No state estate or inheritance tax at the local level, though Washington does levy one statewide
Washington levies its own state estate tax on estates above a statewide exemption threshold (distinct from the federal estate tax) -- a real, current consideration for high-net-worth Kirkland residents that this record discloses rather than omits; confirm current thresholds directly for any actual estate-planning decision.
