Tax refund processing timeframe extended to allow processing of electronically filed returns with refund claims until the prescribed April deadline. The Board, under its section 119 authority, further relaxes the time in the second proviso to sub section (1) of section 143 to permit processing of electronically filed returns with refund claims up to AY 2020 21 that had become time barred; such returns should be processed by 30.04.2024, with all other terms of the earlier orders remaining unchanged.
