You're Overpaying Property Taxes. Here's How Much.

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. All editable documents — review and customize before filing.

Your appeal documents are generated on the fly and immediately deleted — we don't store them. We keep your name and email from purchases so we can send you filing reminders and product updates. If you sign up for monitoring, we store your email and parcel number to notify you of future assessment changes. We never sell or share your data with third parties.

You present your comparable sales evidence to a BOE panel. The Assessor's office also presents their valuation. Hearings last 15-30 minutes — you can attend in person or by phone. The BOE mails their decision afterward.

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.

Since you receive your appeal documents immediately upon purchase, we generally do not offer refunds. If you experience a technical issue that prevents you from receiving your documents, contact us at kingcountytaxappeal@gmail.com and we'll make it right.
