Portland Property Tax FAQs

Figuring out how your property taxes are calculated are notoriously confusing. We tried to break it down for you:

How do I find out how much I owe?

Tax bills are mailed out by Oct. 25th every year. If you haven’t yet received your tax statement, you can find it online, or email the tax office.

Here’s how you can look up your statement online:

1. Go to www.multcoproptax.org and click “Guest Login”

2. In the box marked “Search Information” enter your address. DO NOT include your street type like Ave., St., Blvd., etc..

3. Click on your name or address Click on the “Bill” tab

4. Click on the tax year you would like to see  to download a copy of that year’s tax statement

How are my taxes calculated?

The county performs two calculations every year and the county charges you the lesser of the two.

1. Your Assessed Value is multiplied by the tax rate for your code area; then any Special Assessments (bond measures, etc.) are added.

2. Your Real Market Value (RMV) is multiplied by the Measure 5 limits of $5 per $1000 for Education taxes (or .005 x RMV) and $10 per $1000 for General Government taxes (or .010 x RMV). This amount is then added to the amount for items that are excluded from the Measure 5 limits.

You can find your Assessed Value and Real Market Value (RMV) on the left side of your tax statement. And your “Code Area” at the top in the center. To find out what tax rate corresponds to your Code Area, you can download the 2018-2019 Levy Code Rates here.

You will find your taxes broken down by Education, General Government, and Special Assessments (“Bonds and Misc Taxes”) on the right side of your tax statement:

The section highlighted in green at the bottom is the “Special Assessments” taxes that are exempt from the Measure 5 limits listed above.

Below is how the two tax rates are determined using this example:

In this example, the lower of the two total taxes is the one calculated using the Assessed Value ($8,564.02) instead of the Real Market Value ($8,964.73). So this property’s taxes are $8654.03 for the year. Using the RMV calculation (rather than the Assessed Value Calculation) to determine property taxes is referred to as “Compression” and is the product of Measure 5 that was passed in 1990; it is used to keep property taxes from shooting up when property values increase rapidly.

3. Can I lower my taxes?

Yes! If you think your taxes were calculated incorrectly, you can file an appeal with the county. But your appeal must be filed by DEC. 31. Appeals will only be considered based on the following:

1. Value: You can appeal the current year’s Real Market Value (RMV), Specially Assessed Value (SAV), or Assessed Value (AV).

2. Exception event: if improvements have been made to your property (though updates or remodeling) and you believe that the amount the Assessor has increased the value of your property is too high, you can appeal the amount of the increase associated with the improvement (or exception event”).

3. Penalty: if you disagree with a penalty assessed to you for late filing of your return, you may petition to wave the penalty.
