Who should use Form CT-1127?
Use Form CT-1127 if your Connecticut filing situation requires an extension of time to pay, and you can explain why paying the tax by the original due date would cause undue hardship. The form may apply to Connecticut resident, nonresident, or part-year resident income tax returns.
Does Form CT-1127 extend the time to file my Connecticut return?
No. Form CT-1127 is only an application for more time to pay. If you also need more time to file Form CT-1040 or Form CT-1040NR/PY, use Form CT-1040 EXT and attach Form CT-1127 on top of that filing extension request.
Does Form CT-1127 stop Connecticut interest or penalties?
If Form CT-1127 is approved, Connecticut says no penalty will be assessed if the tax due is paid on or before the end of the extension period. Interest still accrues on any balance due from the original due date to the date of actual payment. If the extension is denied, or the tax is not paid by the end of the extension period, a penalty may apply.
