The Board of Tax Appeals (BTA) is a full-time administrative tax court that adjudicates tax-related appeals.  The BTA is made up of three board members who are appointed by the Governor, with the consent of the Senate.  Each board member serves a six-year term.  Board members qualify based on their training and experience in state and local tax matters.  At the time of appointment, no more than two of the three board members may be members of the same political party.  Appointments of BTA board members must ensure that at least two of the BTA members are attorneys licensed to practice law in Washington and possess substantial knowledge of Washington tax laws.  In addition, one attorney board member must have substantial experience in developing a record suitable for judicial review.  Any nonattorney board member must have substantial experience in residential and commercial appraisals.

The BTA also includes three tax referees who hear and decide tax matters, and five supporting staff, including an executive director. 

Each BTA board member must attend at least 20 hours of judicial training, including Washington law, evidentiary procedures, and judicial practice and ethics.  Board members will receive an annual salary equal to members of class four boards.  The BTA must operate on a full-time basis, and each board member must devote his or her full time and efforts in the discharge of his or her duties.  The board members may delegate administrative powers to the executive director.  The BTA may conduct business when one board position is vacant.

The BTA hears tax appeals from decisions of the County Board of Equalization and the Department of Revenue (DOR).  The most common types of appeals are property tax valuations, property tax exemptions, assessed value direct appeals, and excise tax appeals.  Most appeals must be filed within 30 days of the mailing date of the decision or determination being appealed.  The BTA has no authority to accept an appeal filed after the deadline. 

An appeal can be informal or formal.  A decision on an informal appeal may not be appealed to superior court, but a party may challenge the BTA on its initial decision or may ask the BTA to reconsider a ruling.  A final decision on a formal appeal may be appealed to superior court. 

A nonattorney member of the BTA may have valuation experience as an appraiser accredited by the DOR.  

The title "tax referee" is changed to "tax appeals officer."  A tax appeals officer may be designated by the chair to serve pro tem when a position on the BTA is vacant, or a BTA member is recused, is disqualified, or otherwise cannot hear and consider a particular case set for full board review.

The Governor will set the salaries of the BTA members.
