Learn moreNo state income tax, with a real, narrow-base exception
Washington levies no state individual income tax. Its real capital gains excise tax (enacted 2021, upheld by the WA Supreme Court in 2023) applies to long-term capital gains above an annual threshold at 7%, rising to 9.9% above $1 million in gains as of the 2025 expansion -- a genuinely narrow-base tax reaching only a small share of high-earning taxpayers.
A genuinely high combined sales tax rate
Shoreline's combined 2026 sales tax rate is 10.5% -- Washington's 6.5% state base plus a 4.0% city/local component -- among the higher rates documented across this build's Washington Tier B markets.
Property tax at King County's highest-in-state countywide rate
Shoreline's effective property tax rate runs at approximately 0.83% -- the same King County countywide average established in this project's companion bellevue-wa.js record, and the highest countywide rate of Washington's 39 counties. Specific levy rates vary by exact taxing district; confirm a specific parcel's bill directly with the King County Assessor.
Homeowners insurance: a coastal, non-hurricane-exposed market
As a Puget Sound-region city with zero hurricane exposure, Shoreline homeowners insurance costs are chiefly driven by home value and regional earthquake risk rather than storm-surge exposure. Confirm current premiums directly given Shoreline's genuinely elevated home values.
Key takeaways
- No state income tax, though Washington's real capital gains excise tax (7%-9.9%) applies to high earners statewide.
- Shoreline's combined 10.5% sales tax rate runs on the higher end of this build's Washington Tier B markets.
- Property tax (approximately 0.83% effective) follows King County's countywide rate -- the highest of Washington's 39 counties.
- Zero hurricane exposure, though genuinely elevated home values still drive insurance costs upward.
