Prepare an extension payment

Details on Form IL-505-I and late penalty criteria

The Illinois Department of Revenue has a Fail to Pay penalty and a Fail to File penalty, each subject to making payments by a certain due date.
The Illinois Department of Revenue doesn't support electronic filing of Form IL-505-I via 3rd-party software such as UltraTax CS or Onvio.
The Illinois Department of Revenue gives a means for taxpayers to make payments online or via telephone.

To avoid Fail to Pay penalty, the taxpayer needs to pay 100 percent of the tax liability by the original due date, April 18, 2023. Filing federal Form 4868 or Form IL-505-I without payment has no effect on the calculation of the fail to pay penalty.
To avoid the Fail to File penalty, the taxpayer needs to pay 100 percent of the tax liability by the extended due date, October 16, 2023. Filing federal Form 4868 or Form IL-505-I by the original due date isn't necessary to waive the fail to file penalty.
Since Illinois doesn't have an extension request, the previously mentioned penalties depend only on the timing of payments. Use Illinois Form IL-505-I to make an extra payment by the April 18, 2023, due date to avoid penalties.

Enter extension data

Have UltraTax CS calculate the extension payment amount based on the current data entered
:
Enter
X
in the
Calculate Extension

, the
Federal
tab, then
Extensions
to select the method for calculating the extension payment amount.
note

,
Print Extensions
to select multiple clients at once for electronic filing, UltraTax CS marks the

checkbox isn't marked.
Force the extension payment amount with Form IL-505-I
: Enter an amount in the
Balance due on extension (Force)
field on the ILExt screen.
If there's no balance due, or no calculated amount
: Per the request of the Illinois Department of Revenue, UltraTax CS doesn't produce Form IL-505-I if there's no payment amount since the form is intended solely as a voucher that accompanies a payment. The Department doesn't accept or process Form IL-505-I unless there's an accompanying payment.

Prepare the return after filing an extension payment

Amount actually paid with extension
: The amount paid with an extension is reported in the Payments and Refundable Credit section of Form IL-1040. Enter the amount on the ILExt screen in the
Extension payment actually made; reportable on main return
field. UltraTax CS populates this field when you create the extension if the application calculated the extension payment amount, or if you forced the extension payment amount. Change the data entry for this amount if the taxpayer paid some other amount.
tip
If you filed an extension via some means other than UltraTax CS, enter the actual amount paid with the extension in the
Force
field. This will automatically complete data entry in other fields, including fields for extended due date and the amount actually paid with the extension.
Date return filed
: Enter the
Date return filed
on the ILPen screen. If the date exceeds the extended due date, UltraTax CS calculates a late penalty on the unpaid balance due.
Extension not required to be attached to return
: The Illinois Department of Revenue doesn't need a copy of Form IL-505-I when filing Form IL-1040.
