If you are filing a tax return with a payment due, you will have the option to include payment information when filing the return.

You can view this notice in MyTax Illinois by selecting “View more account options” and then “View Account Letters” in the “Letters and Messages” panel. While you are not actively being billed for any balance corresponding to the notice during the time that you are waiting for a review of your correspondence, a balance due may still display in MyTax Illinois.
