Appraisal and Appeals

Need to review the county's appraisal and value on a property? Or want to appeal a property tax assessment? You're in the right place.

What's an appraisal?

An appraisal is when a registered property appraiser determines if a property is taxable, and gives it a value. This means they look at a property and decide how much it is worth. The tax you owe on the property is based on this value. Click here for more information

Is your property taxable?

The kinds of property you pay taxes on are:

  • Privately owned property (land, buildings, fixed machinery and equipment)
  • Manufactured homes*
  • Personal property used in a business (assets)

*If a county assessor decides that the total assessed value of a personal property manufactured home is less than $40,000, the tax is canceled. This amount can change each year.

What's not taxable property?

The kinds of property that you generally do not need to pay taxes on are: 

  • Household goods like furniture, clothing, tools used for personal use
  • Personal belongings and automobiles
  • Crops
  • Orchards
  • Farm machinery and equipment
  • Most property used for religious, fraternal, and governmental purposes
  • Environmentally Sensitive Logging Equipment

The Oregon Department of Revenue (DOR) appraises certain large industrial sites, and utility property.

What is taxable business personal property?

Taxable business personal property is machinery, equipment, furniture, etc., that has previously or is currently being used in a business (this includes anything in storage).

A business that owns or has taxable business personal property must file a Confidential Personal Property Return with the County Assessor in the county where the property is located by March 15. If the assessor determines that the total assessed value of the business's personal property in the county is less than $20,000, the assessor will cancel the tax. This amount can change each year.

What's an appeal?

An appeal is when you don’t agree with the property value on your tax statement. You have the right to file an appeal with the Board of Property Tax Appeals. You must file an appeal before December 31 of the current year. If December 31 falls on a weekend or holiday, the filing deadline will be the next business day.

The board is made up of independent citizens who will hear your appeal and make a decision about the value of your property, not the amount of tax you pay. Click here for more information or call (503) 846-3854.
