Who We Are
The Board of Tax Appeals for Washington State (BTA or State Board) is an impartial and inexpensive forum for state tax appeals. Our Mission is to resolve appeals of taxpayers and taxing authorities to maintain public confidence in the state tax system.
How We Can Help
The Board of Tax Appeals is the only state-level independent administrative forum available for citizens and businesses to inquire as to the correctness and legality of their tax liability. The Board is committed to fairly and impartially resolving the appeals brought before it.
By law, the assessor’s value on your property is presumed to be correct. That presumption may be overcome only by the presentation of clear, cogent, and convincing evidence, which is evidence showing that it is highly probable that the assessor made a mistake.
Whenever you file/send/deliver a document to the board, you must also provide a copy of the document to the opposing party.
