How Property Taxes Work in Snohomish County
The Snohomish County Assessor values real property at 100% of its true and fair market value as of January 1 and updates values annually. Your bill is that assessed value, minus exemptions, multiplied by the combined levy rate of the state, county, city, school district, and special districts like fire protection and library systems. Tax rates are expressed per $1,000 of assessed value.
Washington operates a budget-based property tax system. Most taxing districts can increase their regular property tax levy collections by only 1% per year without voter approval, plus allowances for new construction.
When property values rise faster than adopted budget levies, tax rates automatically adjust downward, so an increase in your assessed value does not necessarily lead to an equal increase in your tax bill.
What matters most is whether your property's value changed at a faster rate than the average change across your taxing district.
Our median effective property tax rate (tax bill ÷ assessor's market value) accounts for exemptions and deductions, making it more accurate than the general median tax rate, which is the midpoint of statutory rates before adjustments.

What is the Median Effective Property Tax Rate?

How to Appeal Your Property Taxes in Snohomish County
You can appeal your assessment in Snohomish County if your assessed value is higher than your home's true and fair market value as of January 1 of the assessment year.
Review your change of value notice
The Snohomish County Assessor mails change-of-value notices when assessments change, typically in spring or summer. Check your home's assessed value, land value, square footage, and property characteristics for errors.
File with the County Board of Equalization
Submit your formal petition to the Snohomish County Board of Equalization. The filing deadline is July 1 of the assessment year or within 30 days after your change-of-value notice was mailed, whichever is later (up to 60 days in select counties).
Assemble market evidence
Gather sales of comparable homes in your immediate area that sold on or before January 1 of the assessment year, an independent fee appraisal, or photos documenting property condition issues. In Washington, the assessor's valuation is legally presumed correct, so the burden of proof rests on the homeowner to demonstrate improper valuation.
Board of Equalization hearing
The Snohomish County Board of Equalization reviews the evidence submitted by both you and the assessor and determines the market value of your property.
Further appeal
If you disagree with the Board of Equalization's decision, you can file an appeal with the Washington State Board of Tax Appeals within 30 days of the decision mailing date, or pursue action in Superior Court.
