Thank you for your assistance in providing data to the general assembly. Tax year 2010 was the final year for reporting. Tax year 2010 corporate information reports were due by October 15, 2011 for calendar year taxpayers, or seven months after the original due date of the Maryland tax return of the group member with the latest tax year start date. Tax year 2009 reports should have been submitted for calendar year taxpayers; the due date for non-calendar year taxpayers is seven months after the original due date of the Maryland tax return of the group member with the latest tax year start date.

As of June 2015 this application has been taken offline and is no longer available, we apologize for any inconvenience.
