Individuals residing in Connecticut are granted an automatic 6-month extension of time to file the state tax return if having an approved federal extension.

If you do not have a federal extension, or you need only a Connecticut state tax extension, file a separate extension form on or before the due date of the return to get a six-month extension of time to file a Connecticut income tax return. Note: It is necessary to include a reason if you request for the Connecticut state-only extension.
