IL Attachment No. 19
Read this information first -
We encourage you to let us figure your penalties and send you a bill instead of completing
this form yourself.
We will waive the late-payment penalty for underpayment of estimated tax if you timely paid the lesser of 100 percent of the prior year’s (2019
or 2020) tax liability or 90 percent of the current year’s tax liability. If you elect to complete Form IL-2210, this form reflects that waiver.
The late-payment penalty for underpayment of estimated tax is based on the tax shown due on your original return. Do not use the tax shown
on an amended return filed after the extended due date of the return to compute your required installments in Step 2.
