Estimates for tax year 2025-26, worked out from every home's own taxed and market values in Metro's records (2026-07-17) and the county's rate table, with the Measure 5 cap applied home by home.

The figures on this page are estimates for comparing areas. They are not a tax bill, an appraisal, or tax, legal or financial advice. They come from public records: Metro's Regional Land Information System and the tax rate tables of Washington, Multnomah and Clackamas counties, for the tax year shown. Public records can contain mistakes, and rates change every year as voters approve bonds and levies. Your real tax depends on the home's own assessed value, any exemptions or special assessments, and the county's final figures. Before you rely on any figure, check it with the county assessor or a tax professional. Jen is a licensed Oregon real estate broker, not a tax adviser.
