How it works
Property taxes in Multnomah County are calculated using a property's assessed value and the combined tax rates of all taxing districts that apply to the parcel. In Oregon, assessed value is defined as the lesser of real market value or maximum assessed value. Maximum assessed value generally increases by no more than 3 percent per year, except for statutory exceptions. The combined rate depends on the property's levy code area and is subject to constitutional Measure 5 limits.
Examples
If a property's assessed value is entered and the combined local tax rate for its levy code area is applied, the estimated property tax is calculated by multiplying the assessed value by that combined rate. Properties in different levy code areas within Multnomah County can have materially different tax outcomes.
Limitations and important notes
This calculator provides an estimate only. Property tax rates in Multnomah County vary by levy code area, and Measure 5 compression, exemptions, special assessments, and statutory exceptions to assessed value growth are not fully reflected. The actual property tax bill may differ from the estimate.
FAQs
Is this an official Multnomah County property tax bill?
No. This tool provides an estimated property tax and does not represent an official tax bill.
Why do property tax rates vary within Multnomah County?
Rates vary because each property is assigned to a specific levy code area with its own combination of county, city, school, and special district tax rates.
Does this calculator apply Measure 5 or Measure 50 limits?
No. The calculator assumes the assessed value and tax rate entered already reflect applicable limits and does not independently apply Measure 5 compression or Measure 50 calculations.
Can my actual Multnomah County property tax differ from the estimate?
Yes. Actual taxes depend on official assessed value, applicable levy code area rates, and constitutional limits that may reduce taxes through compression.
