The King County Assessor's Office estimates the market value for tax purposes. The assessed value is the market value minus any applicable exemptions or limits determined by local laws and offerings. The tax assessed value is the figure used to calculate your property taxes or the amount multiplied by your tax rate to get your tax bill.

Property Tax Appeals in Washington
In King County, WA, the property tax protest process allows homeowners to challenge their property tax assessments if they believe they are inaccurate. The appeal process begins with reviewing the assessed value of your property, which is determined by the King County Assessor's Office. If you believe the assessed value is higher than the market value, you can file an appeal with the King County Board of Equalization, the body responsible for hearing appeals.
To initiate an appeal, homeowners must submit a completed appeal form, which includes evidence supporting their claim that the assessed value is incorrect. This evidence can include recent sales of comparable properties, an independent appraisal, or any other documentation that demonstrates the property's market value is lower than the assessed value. It's crucial to file the appeal within the specified deadline, typically within 60 days of receiving the assessment notice.
The Board of Equalization reviews the submitted evidence and may schedule a hearing where homeowners can present their case. During the hearing, both the homeowner and a representative from the assessor's office can present their arguments. The board then makes a decision, which could result in a reduction, increase, or no change to the assessed value.
Ownwell assists homeowners throughout this process by providing expert guidance and support. Our team of professionals can help gather necessary evidence, prepare the appeal, and represent homeowners during hearings. With Ownwell's expertise, homeowners have a better chance of achieving a favorable outcome, potentially lowering their property tax bills and ensuring they are not overpaying.
Exemptions in Washington
King County offers several property tax exemption programs designed to alleviate the financial burden on eligible homeowners. One of the key exemptions is the Senior Citizen and Disabled Persons Exemption, which is available to homeowners aged 61 or older, or those who are retired due to a disability. To qualify, the property must be the applicant's primary residence, and there are income thresholds that must be met.
Another vital exemption is the Home Improvement Exemption, which benefits homeowners who have made improvements to their primary residence. This exemption allows for a temporary reduction in the assessed value of the home, effectively lowering the property tax bill for a specified period.
Additionally, the county provides a Disabled Veterans Exemption for veterans with a service-connected disability. This exemption also requires the property to be the veteran’s primary residence and offers significant tax relief depending on the level of disability.
Homeowners can apply for these exemptions by submitting the necessary forms and documentation to the King County Assessor's Office. Ownwell can assist homeowners in navigating the application process, ensuring all criteria are met and maximizing potential savings. By leveraging these exemptions, homeowners can significantly reduce their property tax burden, making homeownership more affordable.
