King County Property Tax Appeal: Common Questions

A complete appeal packet: (1) a cover letter addressed to the BOE, (2) a Valuation Evidence report with comparable sales analysis and adjustment grid, (3) a pre-filled BOE Petition Form, (4) hearing preparation notes with talking points and sample answers to Board questions, and (5) a step-by-step filing checklist with deadlines and instructions.

Technically the BOE can adjust in either direction, but in practice this is very rare. They almost always either reduce the assessment or leave it unchanged.
