Farm and forestland deferrals allow residents to defer a portion of their property taxes to a later date if they meet certain criteria, like acreage size and land use.
In 1961, Oregon passed legislation to adopt Special Assessment Laws for Agricultural and Forestry practices. The Legislature recognized that Agriculture and Forestry significantly contribute to Oregon’s Character and economy. As an incentive to promote agriculture and Forestry practices, Oregon offers several Special Assessment Programs. These programs reduce the property tax the landowner pays annually- if the owners agree to manage the property primarily for farming or for growing and harvesting timber.
To apply for either deferral, you will need to apply to the Clackamas County Assessor to determine if your land qualifies.
