If you've printed an extension by selecting
File
,
Print Extensions
, or have entered an amount in either the
Balance due on extension (Force)
field or the
Tentative corporate net income tax (Force)
field, the extended due date automatically appears in this field. Otherwise, enter the date to be used as the extended due date when calculating the late filing penalties and in the filing instructions. If this field is blank, the application assumes that the return wasn't put on extension.
