Exemptions and Senior Deferral

You may be entitled to exempt a portion of your property taxes if you meet certain qualifications.


Oregon Law provides a residential property tax exemption for qualified military service members that exempts up to $96,283 of the assessed value of their home for 2021. To claim this exemption, qualified military service members should file an Oregon Active Duty Military Service Member's Exemption Claim form along with the required documentation. If the service member dies while performing the qualified service, the person occupying the deceased service member's home may file for the exemption.

The service member must be serving under Title 10 or deployed under the Emergency Management Assistance Compact. They must serve at least 179 consecutive days, with at least one day falling within the tax year for which the exemption is claimed.


If you are a disabled veteran — or the surviving spouse of a veteran — you may be entitled to exempt a portion of your property taxes.


If you are disabled, collecting federal Social Security disability benefits and a homeowner in Clackamas County, you may qualify for the Disabled Citizens' Deferral.

If you are at least 62 years of age and a homeowner in Clackamas County, you may qualify for the Senior Citizens' Deferral.


Churches, schools and other organizations may also claim a property tax exemption.
