Multnomah County Property Taxes

Curiously enough, it wasn’t until the 18th century that the United States adopted tax systems. In the state of Oregon, there is no state property tax– this means the property tax rate in Oregon is determined by the hands of the local government– the counties.

Among the 1,200 local taxing districts in the state, on average, homeowners in Oregon pay property taxes that are slightly below the national average by .17%. However, Multnomah County has the highest property tax rates in the state and is the largest single source of revenue in the County’s General Fund– 60% to be exact.

If you’re interested in more information regarding an overview of property tax in Multnomah County, visit the Oregon Department of Revenue. For property tax records, you can set up an account at and find your account number/property ID. You’ll be using this later to look up Multnomah County Property tax records.

Curious how property taxes work in Multnomah County? First off, property tax is also referred to as an ad valorem tax which is the amount of money an owner has to pay based on the assessed value (taxable value) of the property being taxed.

Real property taxation in Multnomah County has the following steps:

  • Establish tax rates
  • Evaluate market value
  • Collect the tax
  • Distribute the money to taxing districts

Multnomah County Assessment, Recording & Taxation Department (DART)

Unlike most counties in the United States, Multnomah County condenses all the typical duties of the Multnomah County Tax Assessor, treasurer, and tax collector into one single government department known as the Multnomah County Assessment, Recording & Taxation Department (DART). ​​DART has the following responsibilities:

  • Finds the fair market value of your property
  • Analyzes trends in sales prices, construction costs, and rents to estimate the value of all assessable property
  • Maintains maps of parcel boundaries
  • Keeps track of ownership changes
  • Keeps descriptions of building and property characteristics up to date
  • Keeps track of individuals and properties eligible for exemptions and other forms of property tax relief
  • Collects taxes and revenues

Multnomah County’s Board of Commissioners set the tax rates whereas the increases and assessments must comply with the Revenue and Taxation Code, State Constitution, Probate Code, Government Code, and section 11b, Article XI of the Oregon Constitution. The current Multnomah County tax system started in 1997 when state voters passed Ballot Measure 50 in order to limit the rate of growth of property value subject to taxation. This limit means that:

  • The tax assessed value cannot increase more than 3% per year
  • Property taxes are not reassessed when a home sells.
  • The real market value (RMV) of a home and the tax-assessed value are two different numbers.

On average, Multnomah County has an assessed fair market value of .99%, meaning 99% of the property’s value is subject to tax.
