Power of Attorney Procedures and Form

Power of Attorney allows an individual to act as the authority for another person in specific instances. Indiana Department of Revenue (DOR) requires a Power of Attorney form (POA-1) for customers to authorize another person to have access to their information.

Taxpayers who authorize a representative to have Power of Attorney on their behalf for state tax matters must have a properly completed POA-1 form, which must be submitted to DOR in one of the following ways:

  • By mail with a hardcopy of the original
  • By fax as a copy of the original

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

The Indiana Taxpayer Information Management Engine (INTIME), DOR's new, 24/7, e-services portal at, allows tax preparers to submit an electronic Power of Attorney (or ePOA) request to streamline the establishment of a POA relationship.

Two step-by-step guides are available to help with the process of approving ePOA and tax practitioner access to a client’s tax account(s):

INTIME enables customers to view account information and correspondence online, pay taxes and bills, register tax accounts, file business taxes, and message securely with DOR Customer Service. Through INTIME, tax preparers also have increased access and functionality including:

  • Access to view and manage multiple customers under one login
  • Ability to file returns, make payments, and view file and pay history for clients
  • Ability to view and respond to correspondence for clients
  • Ability to request electronic Power of Attorney (ePOA) from clients to act on their behalf
