We were recently made aware of online claims suggesting Congress has created a federal program that waives or modifies property taxes based on age. These claims are not true. Congress has not passed this proposed legislation and there is no federal law or active federal program that alters property tax obligations for seniors.

Washington state does have a property tax relief program for eligible seniors. To determine if you are eligible, and to apply, see the information below.

Below you will find a link to destroyed property tax relief information which you can use if your property suffered damage during the recent storms, and links allowing you to apply for a property tax exemption if you are a senior, a disabled veteran, or a disabled person, if you meet the program requirements.

You can also find information on your property’s value, details and data on our property tax system, how to appeal your property value, and information on our office.

Please don’t ever hesitate to contact us. We are here to help!

The State of Washington has given us a powerful tool to help seniors remain in their homes. If you are 61 years old, own your home, and make less than $84,000 a year you can apply for an exemption that can potentially save you thousands of dollars on your property taxes. Our office works hard to quickly process these applications. While we do accept paper applications, we strongly encourage you to apply online here: Senior Exemption Portal

Paper applications take far more time and staff resources to process, causing backlogs in our system. To speed things up for everyone, please apply using our online process. If you need help you can call us at 206-296-3920 and a member of our staff can walk you through the process. We want everyone to get the tax relief they are entitled to as quickly as possible!
