How the state system works

Washington commercial property tax overview

County assessors value commercial property, and county treasurers administer billing and collection.

County boards of equalization review many appeals, with Washington Board of Tax Appeals review available.

Washington pages should focus on true and fair value, highest-and-best-use assumptions, income evidence, comparable sales, and county assessor records.

Before you appeal

  • Confirm the local filing deadline and appeal form.
  • Pull the property record card and tax bill.
  • Compare assessed data to actual building facts.
  • Gather income, lease, expense, condition, and sale evidence.
  • Ask whether state-specific equalization or classification rules apply.
