Need help managing your business taxes? This guide walks you through the process of authorizing Kintsugi as your tax representative using a Power of Attorney (POA) if necessary.


Step 1: Check If You Can Share Your State Tax Credentials

Some states allow businesses to grant access by sharing tax login credentials. Here’s how to check:

1. Contact your state’s Department of Revenue

State

Abbreviation

Phone Number

Notes

Illinois

IL

(800) 732-8866

Say agent, say or press 3, enter your Tax ID or say “I don’t have it”.

2. Request your business tax login credentials: username and password.

3. Complete any required verification steps.

If your state provides login credentials, share them with Kintsugi so we can begin managing your tax filings. If not, proceed with authorizing Kintsugi through a Power of Attorney POA.


Step 2: Fill Out the Power of Attorney Form

If credentials aren’t available, you’ll need to complete a POA form to allow Kintsugi to handle your business tax matters.

  1. Gather the necessary details for both your business and Kintsugi before completing the form. See Step 3 for obtaining required information from Kintsugi, which includes the representative information.

  2. Specify the tax types and periods covered by the POA.

  3. Sign and date the form as required by the state.

  4. Notarization is required for the state of Illinois.


Step 3: Get Required Information from Kintsugi

Before submitting the POA, ensure you have the following details from Kintsugi:

  • Name of the Representative

  • Firm Name

  • Identification Number (Attorney License, PTIN, FEIN, SSN)

  • Email Address

  • Address

  • Daytime Phone Number

  • Fax Number

Important:

The POA form must be signed by the Kintsugi representative. If not signed and dated, the POA form will be returned.


Step 4: Submit Your POA Form

Once completed, submit your POA form to the appropriate state tax agency.

  • Follow your state’s submission guidelines (e.g., online, fax, or mail).
