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. Click Here to learn more about levies and our property tax system.


In 2010, 33 of the 44 taxing district requests to voters for funding was 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 in 2007. This value was used to calculate taxes owing in 2009 according to state law.

Levy Limits and Taxing Districts  
print this page 

How do the taxing districts set the tax amount?  Every year the directors, councils or commissioners of all taxing districts meet in open session to determine the amount of taxes to be collected the following year. Public questions or comments are welcomed during this process. Once the budget has been adopted, the amount of taxes to be collected is certified to the County Assessor. The Assessor computes the levy rate required to raise the certified tax for each district and ensures that none of the constitutional or statutory limitations is violated. The County Treasurer mails tax bills on or about February 14 of the year in which they are collected and the receipts are distributed back to the various districts.

What is a Tax Code Area (TCA)?  It is a geographical area in which local entities such as a city, county, school or fire district may assess taxes to sustain its operations. These combined taxing districts make up a Tax Code Area or TCA. In a county as large and diverse a Snohomish, there are hundreds of Tax Code Areas. TCA summaries can be reviewed as part of the Assessor's [Annual Report] for Taxes.

What is the statutory rate limit?  The regular levy of each taxing district cannot exceed a certain rate, which is determined by the type of district. For example, the levy for the county current expense fund cannot exceed $1.80.

What is the $5.90 limit?  The aggregate regular levy rate of all senior and junior taxing districts (not including the state, port districts and public utility districts, emergency medical levies, and conservation futures) cannot exceed $5.90.

What is the 1% Constitutional limit?  Washington's State Constitution limits the regular (non-voted) combined property tax rate to 1 percent ($10 per $1,000) of assessed valuation. Voters may vote for special levies (such as school levies) that are added to this figure. 

What is Initiative 747?  Initiative 747, which was approved by voters in 2001, changed the amount a taxing district may levy. The regular property tax levy of a taxing district is limited to 101 percent of the highest levy since 1985, plus amounts attributable to new construction within the boundaries of the district, increases due to newly constructed wind turbines and/or annexations to the district. Prior to I-747, the limit was 106 percent per Referendum 47. Please note that the initiative does not affect assessed values; it limits the amount a district may levy.

In 2006, I-747 was declared unconstitutional in King County Superior Court. The Attorney General filed an appeal and the decision was upheld by the Supreme Court. In 2007, the State Legislature in special session reinstated the limit factor adopted by the voters under I-747.
