You may qualify for a six-month extension of time to pay your tax. To request this extension, you must file Form CT-1127, Application for Extension of Time for Payment of Income Tax, with your timely filed Connecticut income tax return or extension.

Use Form CT-1040 EXT to request a six-month extension to file your Connecticut income tax return for individuals. This form also extends the time to file your individual use tax. It is not necessary to include a reason for the Connecticut extension request if you have already filed an extension request on federal Form 4868 with the Internal Revenue Service. If you did not file federal Form 4868, you can apply for a six-month extension to file your Connecticut income tax return provided you have good cause for your request.

Form CT-1040 EXT only extends the time to file your Connecticut income tax return. Form CT-1040 EXT does not extend the time to pay your income tax. You must pay the amount of tax that you expect to owe on or before the original due date of the return.

Exception: If you expect to owe no additional Connecticut income tax for the 2011 taxable year, after taking into account any Connecticut income tax withheld from your wages or any estimated Connecticut income tax payments you have made, or both, and you have requested an extension of time to file your 2011 federal income tax return, you are not required to file Form CT-1040 EXT. The Department of Revenue Services (DRS) will automatically grant you a six-month extension of time to file your 2011 Connecticut income tax return. If you did not request an extension of time to file your federal income tax return, but you are requesting an extension of time to file your Connecticut income tax return, you must file Form CT-1040 EXT whether or not you owe additional Connecticut income tax.

File Form CT-1040 EXT on or before April 15, 2012. If your taxable year is other than the calendar year, file Form CT-1040 EXT on or before the fifteenth day of the fourth month following the close of your taxable year. If the due date falls on a Saturday, Sunday, or legal holiday, the next business day is the due date.
