Assessor's Office
Protesting Your Property Value for 2011
The 2011 valuation appeal period has ended for both Real Property and Business Personal Property. However, if you
did not make a written protest to the Assessor, an abatement petition may be filed to the Denver Board of County Commissioners (BoCC) to protest 2011 taxes, property valuation or classification.
An abatement petition to the BoCC may also be filed objecting to a prior year's value, within two years of the issuance of a tax bill measured from January 1 to the year following the year in which the taxes were levied. For example, 2010 property values for which an owner did not file a protest to the Assessor and for which a tax bill was issued in January 2011 may be appealed to the BoCC on or before January 1, 2013.
For a form to appeal tax years 2010 and/or 2011, click here: BoCC Petition and BoCC Instructions. Note: A separate form is required for each property and each year appealed.
