2023 Assessed Values Notices in the Mail
EVERETT – Today, the Snohomish County Assessor’s Office announced that new assessment notices will be mailed to Snohomish County property owners on June 23, 2023. Snohomish County has experienced a very dynamic real estate market over the past couple years. In 2022, the residential market slowed considerably and decreased in many areas. The 2023 assessed valuations for 2024 tax have seen an overall decrease of 3.89% countywide for their January 1st assessment with residential averaging a decrease of 6.61% across the county and commercial averaging an increase of 7.67%.
The Northwest Multiple Listing Service shows a median price decrease of 6.09% total for Residential and Condominiums countywide from January 1, 2022 to January 1, 2023.
“The Assessor’s Office is charged with determining the value of property in Snohomish County, and we have a team of professionals who work hard to be accurate and thorough,” said Snohomish County Assessor Linda Hjelle.
Assessed valuations reflect values for sales of real estate. Property owners can:
The Assessor’s Office is required by law to value at 100% of market value as of January 1st of the assessment year for the annual revaluation. As the price of real estate increases or decreases, your assessed value increases or decreases accordingly. Market sales help to determine that value. The question we are tasked with answering is: What could you have sold your property for on January 1, 2023?
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.

The new January 1st, 2023 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: https://www.snohomishcountywa.gov/Assessor
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: https://www.snohomishcountywa.gov/134/Board-of-Equalization or by contacting the Clerk of the Board at 425-388-3407.
There are programs available for tax relief. For example, the Senior Citizens / Persons with Disabilities Exemption: If you own and occupy a residence or mobile home, and were 61 or older by December 31 the year prior to the current property tax year or were retired because of disability in the year prior to the property tax year, you may qualify for a 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 2022 to qualify for a reduction on your 2023 property taxes. SHB 1355 increased the income threshold limit for the 2024 tax year. The estimated income threshold for 2024 tax for Snohomish County is limited to $75,000 or less. This threshold limit is preliminary and subject to change. The Department of Revenue will publish the official income threshold by August 1, 2023.
