Prepare and submit your evidence
The assessor’s value is presumed correct; you need specific market evidence that it is wrong (WAC 458-14-046). “Taxes are too high” or a large percentage increase is not enough.

Ask the assessor for the comparable sales it used; it must provide them at least 21 business days before your hearing, and new evidence from either side is due 21 business days before it (WAC 458-14-066).

Send petition Form 64 0075 (or the county’s approved version) to the Clallam County Board of Equalization, 223 E 4th Street, Suite 4, Port Angeles, WA 98362.
What evidence does the board accept?
Market evidence: comparable sales from the last five years adjusted to January 1, a recent appraisal, photos and repair estimates. The assessor’s value is presumed correct, and saying taxes are too high is not grounds for a change.
