Reducing Property Taxes A Guide to the Multnomah County Property Tax Appeal

Multnomah County Property Tax Appeal Explained

If you believe a county assessor made an error while conducting an assessment on your property, your only solution is to file a property tax appeal.

In Multnomah County, a property tax appeal may seem like a daunting process. Don’t worry, though! DoNotPay will guide you through the whole ordeal and help you lower your tax bills.

What Is a Property Tax Appeal?

A property tax appeal is a legal dispute between a homeowner who pays taxes on their property and the county assessor who estimated the market value of that property.


If you own real estate, you have to pay property taxes to the government. If you find that your property was estimated to be worth more than the similar ones in your area, you may wish to appeal it.

Note that you cannot appeal your tax bills but only the assessment of your property. For example, if you paid bills for half a year and only then noticed an error in the value of your property, you still need to pay the tax bills that you’ll receive until your appeal is resolved. If your appeal is successful, the property tax you pay will be decreased.

Some common mistakes county assessors make when determining the value of a property are:

  • Excluding the up-to-date land comparables from the calculation when reassessing a property, resulting in tax bills being higher than they should
  • Marking the living area incorrectly, which is especially common if a home has several levels
  • Mismatching the sales price

If you bought your property recently and the assessment turned out way higher than what you paid for it, the county assessor probably made an error. 

Can You Appeal Your Tax Assessment in Multnomah County?

You can appeal the tax assessment of your property in any county, including Multnomah County, OR.

Since appealing your property’s value isn’t a trivial business, the Board of Property Tax Appeals (BoPTA) of Multnomah County advises citizens to contact them personally before making any solid decisions.

After talking with the Board’s officials, you will know whether your appeal can be successful.

You can contact the Board in three ways, which you can see in the table below:

How To Determine Whether Your Assessment Is Wrong

You should contact the BoPTA customer service to reach your local tax consultant. They can tell you without a doubt whether the errors you noticed in your assessment statement look like genuine mistakes.

Further action you should take when deciding whether to appeal your property is:

  • Contacting local real estate agents to perform a market research
  • Digging up information on your home’s history
  • Researching the neighboring homes for comparison

Remember that you are responsible for providing evidence of any errors on your tax assessment statement.

How To Appeal Your Property Assessment in Multnomah County

If you wish to submit a property tax appeal in Multnomah County, you have to fill out the BoPTA form and submit the appeal either in person or by mailing it. Here are the addresses:

BoPTA Addresses for Submitting Your Appeal

In person 501 SE Hawthorne Blvd, Suite 175

Portland, OR 97214

Through mail Board of Property Tax Appeals

PO Box 5007

Portland, OR 97208-5007

You can submit your appeal by December 31. The fee is $20 for each filing. If the BoPTA receives your appeal without the evidence that you paid the fee, you can pay it within 20 days, or the Board will dismiss your appeal. The Board will also reject any appeals sent by email or as a fax.

Note that you can only appeal the assessment made for the current fiscal year. This means that you cannot file an appeal for last year’s assessment.

You are allowed to mail your evidence with the appeal, but you can also bring it to court on the day of your hearing.

The BoPTA can schedule your hearing between mid-February and April 15. You’ll be notified of the date and time five to ten days earlier. Since the hearing cannot be rescheduled, you are allowed to choose a qualified representative to appear on your behalf. If it comes to that, you will have to fill out a separate form and submit it to the Board.

Hearings are also held every week—from Monday to Thursday between 9 a.m. and 2 p.m. They last about ten minutes.
