Boundary Changes and Tax Code Areas
WAC 458-12-140(5) states:
Copy of instrument indicating taxing district boundary changes must be provided to the department. Any instrument indicating the official boundaries of a newly established taxing district, or indicating any change in taxing district boundaries, that is required by law to be filed in the office of the county auditor or other county official, must be filed in triplicate.
The county official must forward two copies of the instrument to the county assessor. The assessor must provide one copy of the instrument, together with a copy of a plat showing the new boundaries, to the property tax division of the department of revenue within thirty days of the establishment of the boundaries of the taxing district.
