What is an Appeal?

An appeal is an opportunity to prove that your property’s estimated value is either inaccurate or unfair through the Assessor’s Office. The Gunnison County Assessor provides several options to appeal property value; however an appeal may only be filed from May 1st to June 8th each year. Reasons for an appeal might include:

  • Items that affect value are incorrect on your property record. You have an unfinished basement, not finished. You have a carport, not a garage. Your home has 1,600, not 2,000 square feet
  • The estimated market value is too high. You have evidence that similar properties have sold for less than the estimated market value of your property
  • If the Assessor’s record of acreage or square footage of land is incorrect, an appeal should be filed

Employees of the Assessor’s office have been trained to be polite and helpful. They will do anything within their means to help you get the information you need for an appeal.. Please view them as an ally, not an adversary.

If you think your value is correct, but your taxes are too high, this is an issue you must take up with the officials who determine budgets for each taxing authority. Taxes cannot be protested through the Assessor’s office. For more information, visit the Taxing Districts page of our website.

Step-By-Step Appeal Procedures

  1. Prepare. Find your property identification number on your assessment notice. Use this number to view or obtain a copy of your property record from the Assessor’s Office. The information on all real property is also available on this website through the property record search function
  2. Review the facts on the property record. Is the architectural style correctly stated? If not, a recent photo of your home will help correct the information. Check the living area of your home, the size of your lot, the presence or absence of a garage or finished basement, the construction materials, the condition and so on
  3. Gather as much information as you can on similar properties in your neighborhood. A search of verified sales by subject property during the study period is available on our reappraisal sales web page. Or ask a real estate broker for sales prices on these properties during the study period. You may also review the entire sales database on this website, by choosing "Sales Search" or "Sales List" on the property record search page
  4. Use the account numbers or addresses of comparable properties to review their property record forms, which will include actual values. Compare the features of these properties to the features of yours. If there are differences, the values of the properties may be different
  5. If you are appealing the value of your business personal property, please see the information on Personal Property Appeals below for applicable dates
