Oregon's fourth-highest tax rate

Steep taxes for eastern Oregon
Gilliam's 1.008% rate far exceeds nearby Grant County (0.761%) and Harney County (0.968%), making it the priciest county by rate in the central-eastern region. The rate more than offsets Gilliam's lower property values.
What $158,400 homes cost to own

Challenge high assessments
Gilliam County's steep tax rate makes accurate assessments especially important—overvaluation hits harder here than elsewhere. If you believe your home is assessed above its fair market value, filing an appeal could yield significant savings.
