DR 0145 - Colorado Tax Information Authorization or Power of Attorney

Form DR 0145 may be used for two purposes:

  1. Tax Information Authorization (TIA). This option appoints other persons as designees to receive and inspect confidential tax information from the Colorado Department of Revenue (Department).
  2. Power of Attorney (POA). This option appoints other persons as attorneys-in-fact to represent and act on behalf of a taxpayer with the Department. 

To authorize an individual to represent a taxpayer before the tax agencies of multiple states, you may instead use the Multistate Power of Attorney form. 

Prior authorizations will remain effective until they are expired, revoked, or withdrawn. Submit a new form only for a new authorization.
