What is third-party access in MyTax Illinois?

Third-party access enables another trusted user, such as a tax preparer, who has his or her own MyTax Illinois logon to have access to your MyTax Illinois account. The owner of a MyTax Illinois account can grant or revoke this access and control which tax accounts the third party can access. A tax preparer with third-party access can log in to MyTax Illinois using the preparer's own username and password to access client accounts all in one location.

To grant third parties the ability to request access to your account, after logging in, select "Manage my Profile" and then "More…," and then in the panel labeled "Access," select "Manage third party access." From this screen, you can indicate that you would like to allow third party access. You will also see which third parties currently have access to your account.
