Online Filing Status Update

The Washington State Board of Tax Appeals is in the process of upgrading its systems to allow for online filing of all submissions.

State Boards of Equalization have been migrated to our online filing system. The WSBTA is now asking county assessors’ offices to volunteer for further testing of the system. Written guidance and in-person training will be available.

Please contact Kate Adams at to volunteer, or with any questions or comments on this project.
