Cindy Portmann Assessor
Typically 42% - 47% of all property taxes that you pay are from voter approved levies. This includes cities, schools, parks, fire districts, and more... Read more

Washington State has a 'budget-based' property tax system, so the taxing districts budgets and voter approved measures determine how much you pay. Simply put, when values decline levy rates increase, when values increase, levy rates decrease. Learn more about levies and our property tax system

In 2012, 13 of the 16 taxing district requests to voters for funding were passed by voters.

The decrease in total residential assessed value county-wide started with the 2008 Jan. 1st assessment and reflected the decline in the market since 2007. Sales that occurred in 2012 will be used to calculate the new 2013 assessments, which will be used to calculate taxes due in 2014. Learn more about annual reports

What laws affect how the Assessor appraises my property?  Washington State law requires Assessors to appraise property at 100 percent of its "true and fair market value" in money according to the "highest and best use" of the property. That means the Assessor must first know what similar properties are selling for, what it would cost to replace it, and what the current interest rates are for borrowing the money to buy or build properties like yours. There are three basic approaches to the valuation of real property:

  1. Market or sales approach: comparison of a property with the characteristics of similar properties that have recently been sold.
  2. Cost approach: estimate of the replacement cost of a structure and adjusting that estimate to account for depreciation.
  3. Income approach: analysis of a property's value based on its capacity to generate revenue for the owner.

What is Market Value It is the amount of money that a willing and unobligated buyer is willing to pay a willing unobligated seller. In other words, it is the price most people would pay for your property in its present condition.

Can I appeal my new assessed value? Yes. If you disagree with the value of your property, call the Assessor's office phone number listed on your Change of Value Notice and ask to talk to an appraiser. The appraiser will be glad to answer your questions and examine the valuation of the property. If you cannot come to an agreement, the appraiser will explain how to appeal with the Snohomish County Board of Equalization (BOE). You must file a completed petition with the BOE within 60 days of when the change of value notice was mailed or by July 1st, whichever is later. Appeal forms are available from the Clerk of the Board at 425-388-3407. The appeal process does not require an attorney, but you will need to present evidence that the Assessor's value is incorrect.
