Updated return filing window extended; staggered additional tax applies based on the duration of delay in filing ITR U. Notification implements the Finance Act amendment extending the ITR-U filing window measured from the end of the relevant assessment year and prescribes a graduated additional tax regime that increases with the duration of delay in filing an updated return; taxpayers filing within successive delay bands incur proportionately higher additional tax, and the mechanism has produced significant filings and additional revenue since inception.
