Example 1: On March 16, 1993, B, a calendar year resident individual, files a 1992 Form CT-1040, reporting a $500 overpayment of Connecticut income tax and claiming a refund thereof. If notice has not been given by the Department by June 14, 1993 that the refund is due, interest shall accrue starting June 15, 1993 to the date of notification by the Department that such refund is due.
Example 2: On April 15, 1993, C, a calendar year nonresident individual, files a 1992 Form CT-1040EXT and pays the $300 balance of the tax tentatively believed to be due. On July 15, 1993, C files a 1992 Form CT-1040NR/PY, reporting a $500 overpayment of Connecticut income tax and claiming a refund thereof. Interest shall accrue on the portion of the refund that exceeds the payment that accompanied the tentative tax return. If notice has not been given by the Department by October 13, 1993 that the refund is due, interest shall accrue on $200 starting October 14, 1993 to the date of notification by the Department that such refund is due.
Example 3: On April 15, 1993, D, a calendar year resident trust, files a 1992 Form CT-1041EXT and pays the $1000 balance of the tax tentatively believed to be due. On July 15, 1993, D files a 1992 Form CT-1041, reporting that the tax due is equal to the tax previously paid. On June 1, 1994, D files an amended 1992 Form CT-1041, reporting a $500 overpayment of Connecticut income tax and claiming a refund thereof. If notice has not been given by the Department by August 30, 1994 that the refund is due, interest shall accrue starting August 31, 1994 to the date of notification by the Department that such refund is due. The limitation under subsection (c) of this section does not apply where, as here, D subsequently filed an amended tax return, even if, as here, the payment that accompanied the previously filed tentative tax return exceeds the amount of the refund.
Example 4: The facts are the same as in Example 3, except that the amended 1992 Form CT-1041 was filed on May 1, 1996. The claim for refund is not a direct result of a change to, correction of or amendment of D's federal tax return. The claim for refund is not timely and cannot be allowed because the claim was not filed within three years from the due date for which such overpayment was made (April 15, 1993).
