What is the IRS cut-off time for filing the Extension form on the due date?

It is midnight 11:59 PM on the deadline date. The actual time depends on the timezone your registered business location falls as per the IRS records.

For instance, If your business is registered in North Carolina on the east coast, and you are filing the extension from your California office on the west coast, you need to file by 9.00 PM (PST) so as to match the 12.00 AM (EST) deadline of your registered business location.
