DOR > Tax Professionals > Power of Attorney Procedures and Form Power of Attorney Procedures and Form

The Indiana Department of Revenue's Power of Attorney (POA-1) form and procedures are intended to balance the need to ensure taxpayer information is secure with the need representatives have in assisting their clients.

Taxpayers wishing to authorize a representative to have Power of Attorney on their behalf for state tax matters need to know the following:

A properly completed POA-1 form must be submitted in one of the following formats to the department:

  • A hardcopy of the original
  • A faxed copy of the original

Only when the department has received the properly completed POA-1 can a department employee speak with the representative about the specific tax type and period indicated in the POA-1 form. Please note that the POA-1 form does not need to be notarized.
