The King County process
The deadline follows your own value notice
King County mails residential value notices in area-based waves. Your petition is due by July 1 or within 60 days from the mailing date printed on the notice, whichever is later. That makes the mailing date and the property record the first two facts to confirm.
02
Build the evidence
We examine comparable sales and property-specific facts that speak to true and fair market value.
03
File and represent
We prepare the petition, submit the evidence, respond to the assessor, and handle the Board hearing.
A complete case, not a generic form
What makes Seattle evidence persuasive
A large percentage increase is not proof that the value is wrong. The board reviews market value, so the case must connect local sales and property facts to a supportable requested value.
Learn how Seattle comparable sales are evaluatedComparable sales
Nearby sales around the valuation date, selected for physical and market similarity rather than price alone.
Property-record accuracy
Square footage, use, view, lot, condition, and other recorded characteristics that may materially affect value.
Restrictions and condition
Easements, development limitations, sensitive areas, deferred maintenance, and supported repair costs.
A specific requested value
A concise explanation of why the assessor's value is high and what the evidence supports instead.

“The process itself was clear, but the result still got my attention. The savings were solid enough to justify letting someone else handle the appeal correctly from start to finish.”

Seattle property tax appeal questions
Does Seattle have its own property tax appeal process?
No. Seattle properties are assessed by the King County Assessor, and valuation appeals go to the King County Board of Appeals and Equalization.
When is a King County property tax appeal due?
A petition must be filed by July 1 or within 60 days from the mailing date printed on your Official Property Value Notice, whichever is later. King County mails notices in area-based batches, so homeowners can have different deadlines.
Can I file a King County appeal myself?
Yes. Filing through King County eAppeals is free, and the county Tax Advisor can help homeowners understand the process. Homespring is for homeowners who want the evidence, filing, and hearing handled for them.
What does Homespring charge?
There is no upfront fee. If Homespring successfully lowers your property taxes, the fee is 25% of the first year's tax savings. If there are no savings, there is no fee.
What evidence helps a Seattle property tax appeal?
Useful evidence can include comparable sales near the valuation date, errors in the property record, easements or development restrictions, and photos or professional estimates documenting condition problems.
