A Colorado tax power of attorney form, also known as “Form DR 0145,” is a legal document that allows a taxpayer to designate an agent or representative to act on their behalf in tax-related matters with the Colorado Department of Revenue. The taxpayer must explicitly outline the powers granted to the agent and can choose to limit or specify the scope of authority within the document.
Additionally, the form needs the taxpayer’s signature and date to validate the authorization. If a joint return is filed, the spouse’s signature is also required. This power of attorney stays valid for four years after signing unless a different date is specified in the document (maximum duration of 10 years).
