[ARCHIVED] 2020 Assessed Values Notices in the Mail

2020 Assessed Values Notices in the Mail


EVERETT – New assessment notices will be mailed to all Snohomish County property owners on June 30th.  The new assessed values reflect the market value of each property as of January 1st, 2020.  State law, RCW 84.40.020, requires that property be valued as of January 1st for taxes payable in the following year.  Many property owners will be looking to see a reflection of the current COVID-19 crisis in the value on their notices.  Sales that occurred this Spring and throughout this year will be used to determine next year’s, January 1st, 2021 assessed value.  


The tables below show the changes in value for residential and commercial properties overall and within different areas of the county.  The change in assessed value for individual properties can vary greatly depending on the characteristics of the property such as location, property type, zoning, age and condition. 

2020 assessed values

The new 2020 assessed values, as well as sales that were used to establish assessments for the past three years are now available on the Assessor’s website at:  


Appraisers will spend the next few months adding new construction to the assessment rolls, so some property owners will receive a new notice of assessed value in the fall for new construction added this year.  The assessment date for new construction is as of July 31st each year for property taxes to be collected the following year. 


County Assessor Linda Hjelle recommends that property owners having questions or concerns about their new assessed values call her office to talk to an appraiser before filing an appeal with the Board of Equalization, as many concerns or issues can be resolved without filing an appeal. 


  • Residential Appraisal may be contacted at:  425-388-6555 
  • Commercial Appraisal may be contacted at: 425-388-3390


Petitions or appeals to the Board of Equalization must be filed with the Board within 60 days of when the notice was mailed or July 1st, whichever is later.  The appeal process does not require that you hire an attorney, but you will need to present evidence that the Assessor’s value is incorrect.  Appeal forms and instructions are available on the Board of Equalization’s website at: or by contacting the Clerk of the Board at 425-388-3407.    


There are programs available for tax relief.  For example, the Senior Citizens / Disabled Persons Exemption: If you own and occupy a residence or mobile home, and were 61 or older by December 31, in the year prior to the property tax year OR were retired because of disability in the year prior to the property tax year, you may qualify for property tax reduction. For example, to qualify for either exemption, your total household income, including social security and disability payments, must be $55,743 or less in 2020 to qualify for a reduction on your 2021 property taxes. Qualification levels were increased for the 2020 tax year due to the passing of 2019 legislation SB5160. The new income levels for the 2020 - 2024 tax years will be  $55,743 or less. 


Information on property tax exemptions and special programs are also available on the Assessor’s website or by calling 425-388-3433.
