2022 Protest Form

If you’ve received your 2022 assessment notice you may have noticed the sharp increase in value and are concerned about your tax bill increasing just as much.  In Idaho the property tax bill does not change equally with the change in assessed value.

Property taxes are budget driven which means the amount of taxes collected is determined by the budgets set by each taxing district – not by the amount at which your property is valued.  This being the case, property taxes cannot be estimated until the fall when all of the taxing districts have had their budget hearings for the year.  To really impact your property tax bill, it is important to participate in your taxing districts’ budget hearings.

So you may be wondering at this point, what is an appeal?

An appeal of the assessed value is an attempt to prove that your property’s estimated market value is either inaccurate or unfair. It is not a complaint about high taxes.  To appeal (or protest) your assessed value you must prove at least one of the following:

  1. Items that affect value are incorrect on your property record. (You have one bath, not two. You have a carport not a garage. Your home has 1,600, not 2,000 square feet.)
  2. The estimated market value is too high. You have evidence that similar properties have sold for less than the assessed value of your property prior to January 1st of the current year.

NOTE: You will not win an appeal because you think your taxes are too high. This is an issue you must take up with the elected officials who determine budgets.

Most appeals can be easily resolved simply by visiting with the appraiser that calculated your assessed value.  If after this discussion you wish to file a formal appeal, the protest form can be obtained from this appraiser.  Protest forms are printed with a control number that is specific to your appeal.  For this reason, blank protest forms are not available on this site.  To get in touch with your appraiser, contact the Assessor’s office at 208-454-7431 or, but first you may find the information on this site helpful.

Your eStatement must be accessed online by establishing a personal profile login.  By accessing your eStatement online, you can review, print, copy or download your annual notice.  eStatements will be available online for five (5) years after the date of posting.

This election applies only to your property valuation assessment notice and/or your property tax notice required by Idaho Code § 63-308 and Idaho Code § 63-902, and to courtesy reminders and notifications, not required by law.  All other notices required by law will continue to be sent via U.S. mail.  You may request a free paper copy of your notice(s) at any time without affecting your online election.

To access your eStatement you will need a computer or other electronic device with an internet browser that supports 128-bit encryption; a valid personal email address; and Adobe Acrobat Reader version 10.0 or above. You can download Adobe Acrobat Reader for free by clicking here external.

You may change your election for electronic delivery at any time utilizing these same methods listed above.  If your delivery election or other profile information is changed you will be sent a confirmation of this change.

Sending notification to the email address on file with the Canyon County Assessor and/or the Canyon County Treasurer has the same legal effect as if the annual or supplemental property notices have been mailed to the property owner via U.S. mail. Failure to retrieve or receive your yearly or supplemental notices as described above, does not invalidate assessment valuation appeal deadlines and does not excuse any late fees or penalties if the amount due is not paid timely, nor does it invalidate any collection procedures as required by law for the State of Idaho.

Your email address will not be used for any purpose unrelated to facilitating the notifications described above.

Canyon County is situated on 604 square miles of prime farmland in southwest Idaho.  It is bordered by Payette and Gem Counties on the north, Ada County on the east, Owyhee County to the south, and Malheur County, Oregon to the west. The Census Bureau has calculated our 2017 population at 216,700. That same year, mobile homes, real, and business personal property totaled over 100,000 parcels with a market value in excess of $18,385,200,000.

The County Assessor is an elected official whose principal function is to determine the market value of all taxable property within the county for the purpose of equitable distribution of property tax burden.  The amount of taxes required is not determined by the Assessor but the individual taxing districts such as Cities, Schools Districts, and Highway Districts…  Taxes are collected by the County Treasurer and distributed to the taxing districts. Additional tax dollars can be billed after voter approval at excess or special levy elections.  If rising property taxes are a concern to you, be sure to vote and attend your taxing districts’ budget hearings.

The Assessor is also charged with registering motor and recreational vehicles, and with disbursing the applicable licenses and permits. The Assessor’s Office is located in the Canyon County Administration Building across from the Courthouse in Caldwell.  We are open from 8 am until 5 pm Monday through Friday, excluding holidays.  We do not close for the lunch hour.  Links to our Parcel Information database and interactive map are always available above for your convenience.
