Filling out the Illinois tax power of attorney takes eight short steps. To generate an up-to-date, personalized POA document, use our form-building software. Then work through the document in order, from the taxpayer's details to the signatures.
Input the Taxpayer’s Data
Enter the taxpayer's full name, ID number, and street address, including city, state, and zip code.

Designate Attorney(s)-in-Fact
You may opt for selecting more than one agent if you desire. Provide the following information about them in the second section of the document:

Indicate the Powers You Are Not Granting
The agents are supposed to be fully able on the Principal’s behalf, including the power to access confidential data. If you do not wish to grant certain powers to the agent(s), check the corresponding box in this part of the form.

Provide Info about the Previous Agents
The creation of the Tax POA implies that all the other previous Attorney(s)-in-Fact will be automatically withdrawn. If you want any of them to keep representing you, enter their details in this part of the form.

Submit the Addresses to Receive Your Notices
If you want your written notices mailed to someone, enter that person's name and mailing address (city, state, zip). Add a daytime phone number as well, so the person can be reached quickly. You are allowed to provide up to three addressees herein.

Put the Taxpayer’s Signature
The Principal should review the data that has been provided above and affix his or her signature. If the Taxpayer filed jointly, the spouse should also sign the paper too. In case the Taxpayer is representing an entity, the signature of the officer or partner will be required.

Put the Agent’s Signature
All of the agents appointed have to sign the document, declaring not to be under suspension or disbarment.

Witness or Notarize the Form (If Needed)
If the agent is not an attorney, a certified public accountant, or an enrolled agent, two adults will have to witness the paper to make it valid and enforceable. The other option is to get the form authenticated by a legal notary.

Tip: Write names exactly as they appear on your tax records. Double-check each ID number before you move to the next step.
A short review before you send the power of attorney saves time. Read each part once more and compare it with your tax records. Look for blank boxes, missing dates and signature lines that were skipped by mistake.
