How do I appeal my property tax assessment in Benton or Franklin County?

Benton County: Call the Assessor’s Office first at 509-735-2394; a simple correction may resolve the issue without a hearing. If not, file a separate petition for each parcel with the Board of Equalization, 7122 W Okanogan Pl, Building E, Suite E330, Kennewick, WA 99336 (509-786-5604). Petitions may be submitted by email, in person at Administration Building E, Room E330, Kennewick, or by mail to ATTN: BOE, 7122 W Okanogan Pl, Building E330, Kennewick. The burden is on the property owner to show the assessor’s value is wrong, using evidence like comparable sales or a recent appraisal.

Franklin County: Call the Assessor’s Office at 509-545-3506 to request a review. If you still disagree, file the official appeal form with the Board of Equalization at 509-546-5855 or 1016 N 4th Ave., Room A102, Pasco. A letter or phone call alone doesn’t count as an appeal. Board decisions can be further appealed to the State Board of Tax Appeals.
