For the individual tax return, Connecticut allows an automatic extension to October 15 if no additional tax is due and if a federal extension request is filed.
If additional tax is due, file Form CT-1040 EXT, Application for Extension of Time to File Connecticut Income Tax Return for Individuals, to request an extension to October 15. If federal Form 4868 has been filed with the IRS, no reason for the request is required. If a federal extension was not requested, the taxpayer must have good cause for the Connecticut request. An extension of time to file does not extend the time to pay tax due.
