Additional forms and information are available at or at 501 S.E. Hawthorne Blvd., Suite 175, Portland.  

Tax increases and collection governed by the Oregon Constitution
Voter-approved Ballot Measure 5Measure 47 and Measure 50 amended the Oregon Constitution to determine how property taxes are calculated across the state. Assessed Values generally increase 3 percent per year on properties. Tax rates will increase based on new bonds or levies approved by voters in a particular area and/or decrease if bonds, or levies, expire. Exceptions apply for new construction. More information on property taxes in Oregon is available from the Oregon Department of Revenue on the property tax page.

Taxes are calculated on the lesser of Maximum Assessed Value (MAV) or Real Market Value (RMV). The result is called Assessed Value (AV). In Multnomah County, Assessed Value for single family homes is about 50 percent of Real Market Value on average with variations by property and area. Within Multnomah County, no true “typical” example of average assessed value (AV) exists.  

Tax rates on individual statements vary because property taxes support 69 local government taxing districts with differing boundaries. These districts include education districts and various branches of local government including cities, Multnomah County, local fire, water and special assessment districts, Metro, TriMet and the Port of Portland. Multnomah County only retains about 24 cents of each dollar collected. The remainder is distributed to other taxing districts.

Countywide, taxes increased 11 percent from 2016

The total of all property taxes and special assessments to be collected for all districts in Multnomah County is $1.779 billion for the 2017 tax year, an increase of 11 percent from $1.602 billion in 2016. 

The two primary drivers of the larger-than-usual increase in taxes levied are the voter-approved Portland Public Schools bond that went into effect this year, as well as significant new construction of residential, multi-family, commercial and industrial properties.
