How to Grant C2 Accounting Secure Access to Your Illinois MyTax Account

To allow C2 Accounting to support your tax and compliance needs, you’ll need to grant us secure access to your MyTax account under your company profile.

This process allows you to control exactly what we can see and access, so we only have permissions related to tax and compliance (not full system access unless you choose to allow it).

Follow the steps below using your Master Login:

Step-by-Step Instructions

1. Log in to your MyTax account using your Master Login credentials.

2. In the top-right corner, click “Manage My Profile.”

3. Click the “More” tab.

4. Under the “Other Users” section, select “Manage Additional Logons.”

5. Click the blue “No” link next to “Allow” to permit the creation of another username and password.

6. Confirm by clicking “Yes.”

7. Click the “Add” link on the right side of the page.

8. Complete all required user information fields.

9. At the bottom of the page, you’ll see a full account access list:

   • Check/uncheck boxes to control which accounts this login can access

   • Select only the account(s) you want your accountant to have access to

10. Click “Submit” in the bottom-right corner.

11. Click “OK” to confirm.

Final Step

Share the newly created username and password securely with your C2 Accounting contact.

Once completed, we will be able to access your account with the permissions you’ve assigned.
