Section 36 of said chapter 62C, as appearing in the 2008 Official Edition, is hereby amended by striking out the third paragraph and inserting in place thereof the following paragraph:-
A request for a refund or credit of an overpayment of any tax where a required return has not been timely filed, shall be made by filing the overdue return within 3 years from the due date of the return, taking into account any extension of time for filing the return, or within 2 years of the date that the tax was paid, whichever is later. A request for a refund or credit of an overpayment of any tax where no return is required shall be made by the taxpayer within 2 years from the time the tax was paid. A request for a refund or credit of an overpayment of tax where the required return was timely filed shall be made within the period permitted for abatement for that return under section 37. Any request for a refund or credit filed beyond these deadlines shall be denied by the commissioner. Where a refund or credit results from an abatement under section 37, the amount of such refund or credit shall be limited to the amount paid, or deemed paid pursuant to section 79, within 3 years of the date that the application for abatement is filed, taking into account any extension of time for filing the return. This section shall not limit refunds or credits otherwise allowed pursuant to section 30 or 30A.
