How it works

Property taxes in Marion 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 specific statutory exceptions. The combined rate includes county, city, school, and special district rates 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 specific taxing districts is applied, the estimated property tax is calculated by multiplying the assessed value by that combined rate. Properties in different locations within Marion County can have different combined rates.

Limitations and important notes

In Oregon, property tax is influenced by assessed value limits and locally adopted rates. When the entered taxable value is multiplied by the combined rate, the calculator returns the estimated annual amount.

FAQs

Is this an official Marion 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 Marion County, Oregon?

Rates vary because each property is subject to a different combination of county, city, school, and special district tax rates based on its location.

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 Marion County property tax differ from the estimate?

Yes. Actual taxes depend on official assessed value, applicable district rates, and constitutional limits that may reduce taxes through compression.
