How are Assessed Values Calculated?
​The Assessor is required by law to annually assess property at 100% of market value and to assure that all values are in equalization. It's important to remember that market value is the price a willing buyer and seller would agree to under ordinary circumstances. This does not mean that an individual sale will automatically establish the value of a property. The Assessor uses multiple sales of comparable properties to establish assessed value. Frequently Asked Questions about The Assessment Process can be found here.
What is the Difference Between Real Property and Personal Property?
Real property includes land and all buildings, structures, and improvements to the land.
Personal Property includes machinery and equipment, fixtures, furniture, and other items that are movable in nature that are owned or leased by a business. Personal effects which are not held for sale or commercial use are not taxable, such as household goods.

How is the Amount of Property Taxes Owed on my Property Determined?
The Assessor determines assessed values, while the taxing districts's budget and voter approved measures determine your taxes. The amount owed that is shown on your property tax bill is based upon the individual taxing district's entire budget and levies. Taxing districts include state, county and city governments as well as schools, and other taxing districts such as hospitals, fire, and sewer districts. To determine your share of the taxes owned, the assessed value of your property is multiplied by the levy rate in your levy area to determine your fair share of the total levied taxes by these jurisdictions.
