Notwithstanding subsections (4), (4.1) and (5), if the result of an assessment or a decision on an appeal is to change a particular balance of a taxpayer for a particular taxation year, the Minister may, or if the taxpayer so requests in writing, shall, before the later of the expiration of the normal reassessment period in respect of a subsequent taxation year and the end of the day that is one year after the day on which all rights of objection and appeal expire or are determined in respect of the particular year, reassess the tax, interest or penalties payable by the taxpayer, redetermine an amount deemed to have been paid or to have been an overpayment by the taxpayer or modify the amount of a refund or other amount payable to the taxpayer, under this Part in respect of the subsequent taxation year, but only to the extent that the reassessment, redetermination or modification can reasonably be considered to relate to the change in the particular balance of the taxpayer for the particular year.
