DOR may grant extensions for filing and paying certain income tax for those affected by natural disasters.

A relatively small number of returns may be suspended for various reasons, including to protect customers against identity theft, federal Schedule C verification, and wage and withholding verification. ITS systematically suspends returns based on internal control parameters for either manual or batch review.
If the customer receives a letter from DOR requesting additional information, all requested documentation must be submitted along with a copy of the letter received by INTIME or mail.

Although a tax practitioner may have a POA to manage a client’s tax accounts, an electronic Power of Attorney (ePOA) is needed to ensure the security of a client’s INTIME account information.
Requesting ePOA access is done through a tax practitioner’s INTIME account. The client will then be notified and can log in to their INTIME account to review and approve the request.
Once approved by the client, you will be able to see and perform the same actions in INTIME as your client.
Step-by-step guides for Tax Practitioners and Clients are available to help with approving ePOA via INTIME and authorizing tax practitioner access to a client’s account(s).
An INTIME ePOA is equivalent to a Form POA-1 for the purpose of discussing tax matters. DOR reserves the right to request a Form POA-1 in certain circumstances. Generally, a Form POA-1 is not required if DOR has an approved INTIME ePOA access request on file. The INTIME ePOA only allows clients to approve access to the accounts currently in INTIME. A Form POA-1 may be needed for other tax types.
The best way to proceed is to have the client create a logon for their INTIME account. If the client does not have the information on hand to validate the account, they may request a “Welcome Letter,” which will be mailed to them.
Step-by-step guides for Tax Practitioners and Clients are available to help with approving ePOA via INTIME and authorizing tax practitioner access to a client’s account(s).
If your client does not have the ability to access INTIME to approve your request, an access request letter will be mailed to their legal address on file with DOR. The letter can be used to approve the ePOA and your access request to INTIME.
POA representatives should mail or fax their client’s signed Form POA-1 to:
Indiana Department of Revenue
P.O. Box 7230
Indianapolis, IN 46207-7230
Fax: 317-615-2605
A PDF file may also be attached to an INTIME message.
No, DOR will not accept the IRS’s POA form. A Form POA-1 must be completed and submitted to DOR.
The POA does not expire. A new Form POA-1 must be completed only if the taxpayer chooses to change their designated representative who can communicate on their behalf with the department.
Yes, a Form POA-1 is still used for power of attorney, but it does not allow access to client accounts in INTIME. An ePOA is needed to ensure the security of a client’s INTIME account information.
E-file Mandate
If a tax practitioner prepares more than 10 individual income tax returns in a calendar year, for the subsequent year, the professional preparer must file returns for individuals in an electronic format. A penalty of $50 may be imposed for each return that is not electronically filed.
The mandate will apply to the firm as a whole. Any returns filed from the firm are subject to the mandate. If an individual who is employed by the firm also has a private practice with more than the mandated number of returns, the individual is required to e-file.
A penalty of $50 per return up to a maximum of $25,000 per calendar year may be imposed for failure to comply with the e-filing mandate.
Indiana state law requires those practitioners who are affected by the mandate to file their returns electronically. Other states’ practitioners have been successful in such situations by telling their clients upfront before conducting any services for them. Form IN-OPT may be signed by the customer in those rare instances where electronic filing is refused. This form must be retained by the practitioner for three years.

A chart of DOR’s Electronic Tax Filing Methods and Options provides more information for all tax types and also identifies those with e-filing-only mandates.
