Property Tax Assessment Values Across Seattle, King County, Washington
When examining property taxes in Seattle, Washington, understanding the distinction between “market value” and “assessed value” is crucial.
The market value is what a willing buyer would pay to a willing seller in an open and competitive market, often influenced by location, property condition, and economic market trends. The King County appraisal district estimates the market value for tax purposes.
The assessed value is the market value minus any applicable exemptions or limits determined by local laws and offerings. The tax assessed value is the figure used to calculate your property taxes or the amount multiplied by your tax rate to get your tax bill.
Assessment notices:
In King County, assessment notices are sent in the spring each year. They’ll typically reach your mailbox by the middle of July.
Each property owner receives an assessment notice that contains both the market value and assessed value, along with an estimate of your property tax bill. The median home price in Seattle is $786,000, and the median tax bill is $7,773, compared with the national median property tax rate of 1.02% and national median property tax bill of $2,400.
