The Assessor's primary duty is to determine the value of all taxable real and personal property in the county for ad valorem purposes. Washington State law requires property to be assessed at 100% of market value. Properties in Douglas County are revalued annually. Contact the Assessor's Office to discuss your valuation. Taxpayers may appeal valuations to the County Board of Equalization.

Tax exemptions are available to seniors 61 and older or persons physically disabled. Agricultural properties may qualify for an open space exemption. Contact the Assessor's Office for information or applications.
