How can I be assessed a penalty on my IL-1040 if I pay the tax by the due date?
You may be assessed a late-payment penalty for underpayment of estimated tax if you were required to make estimated tax payments and failed to do so, or failed to pay the required amount by the payment due date. See Form IL-1040-ES, Estimated Income Tax Payments for Individuals, for more information.
