Property Tax Abatement Information

Abatement Forms

Instructions for Filing a Petition for Abatement or Refund of Taxes
Petition for Abatement or Refund of Taxes 1-year 
Petition for Abatement or Refund of Taxes 2-year


The Assessor’s Office will review the submitted abatement petition and will recommend approval or denial to the Commissioners. The Commissioners may authorize the Assessor to approve petitions for abatement or refund for $10,000 or less in taxes, per schedule, per year, provided the petitioner and the assessor mutually agree to an adjustment. This appeal process is similar to a protest filed during May, but can take many months to complete.


If the petition is granted and taxes have been paid, a refund is issued by the Adams County Treasurer. If you have any further questions regarding your refund, please contact the Treasurer's Office at 720.523.6160.

If the tax dollar amount to be abated is $10,000 or more, the abatement must be approved by the Colorado Property Tax Administrator .
