Purpose and application of chapter.

(1) This chapter explains how informal hearings are conducted before the board of tax appeals (board). The informal process is helpful for those who are not represented by an attorney or do not have legal expertise. These rules of practice and procedure will be liberally construed to secure the just, speedy, and efficient determination of every appeal.
(2) Where procedures are not addressed by this chapter, the board may, upon its own motion or upon written motion of any party, refer to and apply any rule provided for in chapter 456-09 WAC - Formal hearings—Practice and procedure, chapter 10-08 WAC - Model rules of procedure, or the superior court civil rules. This chapter adds but does not replace the provisions of chapter 82.03 RCW.
(3) The superior court civil rules, rules of professional conduct, the Washington Administrative Code (WAC), and the Revised Code of Washington (RCW) referred to in this chapter are available in public libraries and online.

PDF456-10-010

Difference between formal and informal proceedings.

(1) A party making an appeal may choose either a formal or informal hearing in its written notice of appeal. Informal hearings are conducted according to the rules of practice and procedure outlined in this chapter. Formal hearings are conducted according to the Administrative Procedure Act, chapter 34.05 RCW, and the rules of practice and procedure of chapter 456-09 WAC. Failure to choose a type of hearing will result in the proceeding being conducted as informal.
(a) Decisions entered in an informal appeal are not subject to judicial review under the Administrative Procedure Act, chapter 34.05 RCW like formal decisions. Proposed and initial decisions in informal cases, however, can be internally appealed to the board by filing an exception as outlined in WAC 456-10-730.
(b) The informal appeal process is not designed for parties who intend to engage in more than a limited exchange of documents and information between the parties. This exchange process is known as discovery. In cases where a party anticipates discovery, a formal proceeding may be better suited as discovery is conducted according to the Washington state superior court civil rules.
(c) The parties may have additional avenues to challenge allowed by law, but which the board does not have legal authority to grant, and therefore, are not discussed in this chapter.
(2) An appeal may be converted from an informal to a formal proceeding as provided below:
(a) A respondent in an appeal from a decision by a board of equalization pursuant to RCW 84.08.130 may submit a request that the hearing be formal, if made within 20 calendar days of the date the notice of appeal is served.
(b) The department of revenue, in appeals under RCW 82.03.130 (1)(a), may submit a notice of its intention that the hearing be formal, if made within 30 calendar days of the date the notice of appeal is served.
(c) The department of revenue, in appeals under RCW 82.03.130 (1)(e), may submit a notice of its intention that a hearing be formal, if made within 10 calendar days from the date the notice of appeal is served.

If any such person does not follow these rules, the hearing officer has the discretion, depending on the circumstances, to admonish or reprimand such person, exclude such person from further participation in the proceedings, adjourn the hearing, or report the matter to the board. Further, all persons are required to treat all parties, representatives, and the board's staff courteously and fairly both inside and outside the proceedings.
(2) The board in its discretion, either upon referral by a hearings officer or on its own motion, may consider information that establishes to the board a question regarding a person's ethical conduct and fitness to practice before the board. This information will be considered at a hearing after notice to all parties. If the person's conduct is found to be unethical or unfit, the board may take appropriate disciplinary action including, but not limited to, refusal to permit such person to appear or appear in a representative capacity in any proceeding before the board.

Limits on exhibits and evidence.

(1) Each party must indicate the specific pages of evidence it intends to rely on, if any, from the body from which the party appeals. For property tax appeals this includes the record at the county board. For excise tax appeals, this includes audit papers, refund reviews, and exemption applications. For other appeals, this includes documents submitted by both parties to the decision maker below. The actual decision appealed from (the county board ruling, department determination, or the equivalent) is not counted within the evidence limits. Failure to indicate specific page numbers will result in the presumption that the party does not intend to rely on the underlying record, and instead intends to submit and rely only on new evidence.
(2) For property tax appeals, each party is strongly encouraged to submit the following exhibits or evidence in the following instances:
(a) If the party intends to rely on comparable sales, a table of comparable sales. The table should list the sales in order of most similar to least similar to the subject property, and include each sale's age, size, sales price, date of sale, and location relative to the subject property. A suggested format is available on the board's website or by contacting the board's staff.
(b) If the party intends to rely on an income approach, an outline. The outline should at least include the subject property's square footage, contended price per square foot, vacancy rate, operating expenses, income, and capitalization rate.
(c) If the party intends to rely on a cost approach, a cost breakdown that includes the cost elements used and how the costs were determined.
(3) Each party may submit evidence and/or exhibits in support of its appeal; however, submissions are limited to the page limitations below. Excluded from these limits are the actual decisions appealed from (the county board ruling, department determination, or the equivalent) and formal appraisals from a licensed appraiser:
(a) For residential property tax appeals, each party is limited to submitting a total of 75 pages per assessment-year appealed, including the record of the county board of equalization not excluded as outlined above that the party intends to rely on;
(b) For commercial property tax appeals, each party is limited to submitting a total of 125 pages per assessment-year appealed, excluding the subject's rent roll and income statements, but including the record of the county board of equalization not excluded as outlined above that the party intends to rely on;
(c) For excise tax appeals, each party is limited to submitting a total of 250 pages, including the record of the department of revenue not excluded as outlined above that the party intends to rely on;
(d) For all other appeals, each party is limited to submitting a total of 75 pages, including the record of the body from which a decision is appealed, and which the party intends to rely on.
(4) For property tax appeals, each party should submit no more than five comparable sales. If both unimproved and improved sales are necessary, no more than five of each type should be submitted.
(5) A party may file a motion with the board to submit evidence and/or exhibits beyond the page limits up to 500 pages, which the board will grant for good cause. Exceeding the page limits without the board's permission may result in the hearing being continued, or the exclusion of evidence beyond the limits.
(6) The board will not review the record of a county board of equalization or any other tribunal that is unduly large, disorganized, or not numbered.

Limitation on discovery.

(1) If applicable and not in conflict with this chapter, the statutes and court rules regarding pretrial procedures in civil cases in the superior courts of the state of Washington will be used. These statutes and rules include, but are not limited to, those rules about the discovery of evidence.
(2) The informal appeal process is not designed for parties who intend to engage in more than a limited exchange of documents and information between the parties. This exchange process is known as discovery. In cases where a party anticipates discovery, a formal proceeding may be better suited as discovery is conducted according to the Washington state superior court civil rules.
(3) The board may limit discovery on its own motion, or by motion of any party. In doing so, the board will apply the criteria and considerations described in WAC 456-10-001 and other provisions in this chapter.
(4) The board may decide whether to allow depositions, requests for admissions, and any other discovery procedure. The board may condition the use of discovery on a party showing that discovery is necessary and that other means of obtaining such information are not available. In exercising such discretion, the board will consider the criteria outlined in RCW 34.05.446.

Hearing procedure.

Informal hearings are structured similarly to formal hearings, although more relaxed. As such, informal hearings will generally be organized as follows:
(1) All parties and witnesses will be sworn in by a hearings officer to tell the truth;
(2) Each party may then provide a short explanation of what the testimony of their witnesses and evidence will show;
(3) Next, each party may call witnesses to testify, beginning with the party that is appealing. The opposing party will have an opportunity to ask each witness questions, and the party calling the witness an opportunity to ask the witness questions to clarify the testimony; and
(4) Lastly, each party may summarize the testimony and evidence that supports their case, beginning with the party that appealed.
The board or hearing officer may ask a party, a representative, or a witness a question at any time during the hearing.
