Property Tax Assessment Values Across Winthrop, Okanogan County, Washington

Assessment notices are sent in the spring each year. They'll typically reach your mailbox by the middle of May.

Each property owner receives an assessment notice that contains both the market value and assessed value, along with an estimate of your property tax bill.
