Property Tax Relief increased for Senior Citizens, Disabled Persons and 100% Disabled Veterans

After pursuing expansion of this program for several years, the Legislature passed SSB5186 this June, which increases household income thresholds by $5,000 in each section of this program.

This link takes you to our updated Taxpayer Information Bulletin which reflects these recent changes.

"For several years now, seniors and disabled persons have experienced reduced benefit from these programs as household income has increased and the thresholds have fallen out of date. Now, with the recent changes a new wave of seniors and disabled persons will qualify or see increased tax relief."

NOTE: If you are a current program participant qualifying under one of the three levels of exemption, it is not necessary for you to do anything. In order to ensure your 2016 taxes reflect this recent increase in property tax relief, our office will move all participants currently in category C to category B and we will move all participants currently in category B to category A. When you receive your 2016 tax statement next February, these changes will be reflected.

If your income is between $35,001 and $40,000, please follow the link above to determine if you now qualify for this program.

For questions regarding how to apply for this program, please contact our office and ask for our Senior/Disabled program specialist Daniel Janiga (360) 867-2200.

New Website Improvements

Over the past three years I have made increased transparency a top priority. In part, we have achieved this by substantially increasing the scope of information the public can easily obtain on this website. We began by adding a link to a comprehensive cost valuation report for every residential parcel. We have posted all sales and property characteristics to the website. Next we added complete USPAP reports for both residential and commercial properties and expanded the search and research instructions, in order to facilitate taxpayer research.

I took office on 1/1/2011. Now at the 2 year mark, we have turned the corner, in so many ways, that I wanted to detail just what my excellent staff, managers and I have achieved.

Tax Statement Notification

(Posted Feb 2013)

To our valued customers:

Tax statements should reach taxpayers this year, on about February 13th. Even though the value of most properties continued to decline in 2012, for many a combination of factors will produce an increase in your tax liability.

Particularly in these difficult times, it is understandable that many taxpayers have questions as they review their tax statements. We in the Assessorís office continue to work collaboratively with your County Treasurer, Shawn Myers and her staff in order to provide taxpayers improved access to meaningful information about how each taxpayers taxes have been calculated. With this in mind, we have made some additional changes to both web sites and added what we hope will be helpful content. Click here to read more...
