An Illinois personal identification number (PIN) is assigned to you when you file your first IL-1040. First-time filers will not have an IL-PIN assigned until after IDOR receives and processes that first return. To file your Illinois individual income tax return for the first year, you will need to either complete and mail a paper IL-1040 or file through a tax preparer or third-party electronic software. After filing the first year, you will be able to create a MyTax Illinois logon.

From the panel "Inquiries for Individuals," select IL-PIN Inquiry to look up your Illinois PIN using your Illinois Driver’s license, Illinois state ID, or the Adjusted Gross Income (AGI) from your most recently filed Illinois tax return.

Individuals can make estimated, extension, and return payments without a logon for the current tax year.

To make a non-login payment, select “Make an Individual Income Tax Payment” located in the “Individuals” panel. You will be provided with a confirmation code for your payment. Save this code for your records. The code, along with the email address you provide, will allow you to retrieve a record of your payment (using “Retrieve a return, application, or payment” in the “Submissions” panel.) If you do not have your confirmation code you may look it up at Retrieve a Confirmation Code.
