Switching regime in a revised return:
• For salaried or non-business taxpayers, if the original ITR was filed by the due date (139(1)), you can file a revised return (139(5)) switching to the old regime within the revision window (31 December of the AY). The utility and CPC have generally accepted this.
• For business taxpayers, switching to the old regime needs Form 10-IEA by the due date. A revised return can't do it if 10-IEA wasn't filed in time.
• If the original was belated, the old regime isn't available.
