Estimated property tax
Enter the assessed value to see the estimated annual property tax.
How it works
Enter the property’s assessed value and the combined tax rate for your tax code area in decimal form. The estimate multiplies assessed value by the rate you provide. In Multnomah County, tax rates are calculated for each tax code area and may include education taxes, general government taxes, bonds, and local option levies.
Examples
If a property has an assessed value of 500,000 and you enter a combined property tax rate of 0.015, the estimated annual tax would be 7,500 before any special assessments.
Limitations and important notes
This is an estimated property tax calculation, not an official tax statement. Tax rates vary by tax code area within Portland, and special assessments may apply. Exemptions and eligibility-based programs are not automatically included unless reflected in your inputs.
