How do I know if I am eligible to activate a MyTax Illinois logon?

To create a MyTax Illinois logon, you must

  • already be registered with IDOR, IDES, or ILCC to do business in Illinois if you are a business or have a recent history of filing individual income tax returns if you are an individual;
  • have a tax account type currently available in MyTax Illinois; and
  • know the specific business or individual identification information required for activation.

Will I have a separate MyTax Illinois logon for each type of return I file?

No. Activation is based on your Social Security Number (SSN) if you are a sole proprietor or your Federal Employer Identification Number (FEIN) for all other business entity types. This means all tax types under your FEIN or SSN will be accessible through one MyTax Illinois logon. If you obtain a new FEIN, you will need to re-register your business which will require you to sign up for a new MyTax Illinois logon.

If there is not yet an active MyTax Illinois logon for the business, you will be considered the “Master User.” The master user has the ability to allow access to other users.

How often does IDOR process information from MyTax Illinois?

IDOR processes most requests only once a day. However, “Maintain Locations” requests and changes that the master user initiates for logon purposes (e.g. adding new logons or adjusting settings and passwords for existing logons) occur within a minute or two. Requests that are processed only once a day will have a status of “Pending” at the time they are made (e.g. payments or a tax return). Requests will have a status of “Completed” once they are processed. It takes up to five business days for balances to be updated in MyTax Illinois after payment requests are completed.

Can I view notices that IDOR issues to me using MyTax Illinois?

Yes. Many notices issued by IDOR are available to view, download, and print from your logon in MyTax Illinois. Logon to MyTax Illinois and select the “More” to and then select “View Letters.”.
