The first proviso to section 149(1) preserves the earlier reassessment limitation for assessment years beginning on or before 1 April 2021. It prevents notice under the amended regime where notice was already time-barred under the pre-Finance Act 2021 limits. For A.Y. 2015-16, the note identifies expiry of the former six-year period on 31 March 2022; therefore, a section 148 notice issued thereafter is treated as time-barred, rendering the consequential reassessment unsustainable.
