The Appeals Process
1. A notice of appeal form – Notice of Appeal – Informal – Property (form BTA100)
2. Copy of your County Board of Equalization Order or decision.
Note that the State Board cannot hear an appeal on the assessed value of your property unless the County Board has issued a ruling on value. If the County Board declines jurisdiction or otherwise rejects your appeal, you may only appeal that action of the County Board. The form for appealing a County Board action is on our Forms and Publications page.
- New appeals or submissions for existing appeals are accepted by email to the Board at email@example.com.
- New appeals for property tax valuation matters only may also be submitted through the Board’s online electronic filing system.
- Submissions for existing appeals will also be accepted though the Board’s online submissions portal when it becomes available in 2017.
Electronic files received prior to 5 p.m. on a business day are deemed received on that day. Electronic files received after that time are deemed received on the next business day. The time of receipt of an electronically filed document is the time shown by the Board’s electronic mail system or E-filing system.
Unless requested or ordered by the Board, parties should not file paper copies of electronically transmitted documents. This process is approved by this posting, regardless of the requirements of WAC 456-10-325(2)(b) or WAC 456-09-325(2)(b). Note the Board will request or order the filing of paper copies in most formal appeals.
Parties may maintain original documents in their files. The Board does not require an original document or an original signature.
Note that the Washington State Department of Revenue cannot extend a deadline for filing with the Board of Tax Appeals.
See Spieker Properties v King County Assessor, Docket No. 50119 (1996).
If you feel the Board of Equalization did not have the authority, or otherwise incorrectly rejected your appeal, you may file an “Other County Action” appeal with the State Board within 30 days of the date the Board of Equalization rejected your appeal. The State Board will not rule on the value of your appeal, but only on whether the County Board’s action was correct.
Appeal forms are located at our Forms and Publications page. County Assessors or Boards of Equalization may also have forms available. Forms must include all items required under WAC 456-10-310 (informal appeal).
The Board does not provide fill-in forms for formal appeals. Formal appeals should be on pleading paper and contain all items identified in WAC 456-09-310. A pleading paper template is also available at our Forms and Publications page.
Persons representing themselves often choose an informal appeal for property tax matters. Hearings are informal and generally, there are fewer items filed during the course of the appeal. An informal appeal cannot be appealed to Superior Court, but a party may still challenge the Board on its initial decision, or ask it to reconsider any ruling. See WAC 456-10-730 (Exceptions) and 456-10-755 (Reconsiderations). Formal appeals are typically chosen when the parties will be conducting discovery, seeking a protective order, or looking for a ruling on an issue of law. Many of the parties asking for a formal hearing are represented by attorneys or other professionals although representation is not required. Final decisions in a formal case can be appealed to Superior Court under the Administrative Procedures Act, chapter 34.05 RCW. For further discussion of practice before the Board of Tax Appeals, see 33 Gonzaga Law Review 141 for a 1997 article by Laura VanderVeer King. The article includes a discussion of the choice between an informal and formal hearing.
Appeal rights are also available for decisions issued following a formal hearing. See Chapter 456-09 WAC.
A lawyer not otherwise authorized to practice law in Washington may associate with an active member of the Washington State Bar and apply to appear in a proceeding before the Board if the applicant complies with all requirements of APR 8(b). See Out of State Lawyers Practice Before the Board.
Providing the Best Evidence – Property Tax Valuation Appeals
The Board will consider documentary evidence and written and oral testimony. Evidence and testimony should relate to the market value of your property, not the assessed value of other properties. See Bobzin v King County Assessor, Docket No. 32243 (1987).
- Sales comparison approach- Cost approach
- Income capitalization approach
- Or any combination of the three approaches
Market evidence may include: “Any sales of the property being appraised or similar property with respect to sales made within the past five years.” RCW 84.40.030(1).
For residential property the best way of determining market value is usually by sales comparison.
The best sales comparisons are sales of your property or sales of similar properties located in your area which have occurred within five years of your assessment date.Geis v Snohomish County Assessor, Docket No. 60520 (2004).
Sales occurring closest to your assessment date and sales considered the most comparable to your property are given the greatest weight.
Select sale properties that sold closest to your assessment date and are the most comparable to your property.
Property owners in King County can receive additional assistance by contacting the office of the King County Tax Advisor at 206-296-5202.
For each comparable sale be sure to include the account number or parcel number of the property, the address of the property, the date of the sale, and the sale price. Also include as much information regarding the key characteristics of the property as you feel necessary to support your opinion of value.
- Location – sales in the same subdivision or neighborhood are the best evidence.
- Unit of Comparison – lot size; acreage; square feet; waterfront feet.
- Desirable or Undesirable Features – view or waterfront, access problems or wetlands Sewer/Septic System/Water System.
- Type of construction – wood; brick; other.
- Square feet of total finished living area (all floors).
- Year built.
- Number of stories.
- Improvement type and construction quality.
- Building condition.
- Number of bedrooms/bathrooms.
- Appraisals prepared by others.
- Documentation by qualified experts concerning problems.
- Written commercial estimates of the cost to cure problems.
- Photographs, maps.
- Any evidence you wish to be considered must be submitted to the Board by the deadlines given.
See Cone v. Pacific County Assessor, Docket No. 55169 (2000).
Income capitalization or sales comparison approaches are usually given more weight than a cost approach for commercial properties.
Your income capitalization approach should be based upon market conditions. Income and expenses of the property under appeal may also be used. Income, expenses, and capitalization rates must be verifiable and supported. See Regency Park v. Spokane County Assessor, Docket No. 38041 (1990).
You should provide a copy of your income and expense statement and all leases pertinent to the property. If the income or expenses of the property under appeal vary from typical market income and expenses, you must show why such variations are reasonable or typical for the property.
