Gilliam's taxes rank among nation's highest
Gilliam County's effective tax rate of 1.008% places it in the top 5% of U.S. counties for property tax burden. Despite a modest median home value of $158,400, homeowners pay $1,597 annually—well below the national median of $2,690 in absolute dollars, but at an unusually steep rate.
Oregon's fourth-highest tax rate
At 1.008%, Gilliam ranks 4th highest among Oregon's 36 counties, significantly exceeding the state average of 0.775%. Only three counties in Oregon levy higher rates, reflecting Gilliam's reliance on property tax revenue.
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
The median Gilliam homeowner pays $1,597 annually on a home valued at $158,400, driven by the county's high 1.008% rate. Owners with mortgages pay $1,825, while those without pay $1,346.
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.
