For salaried taxpayers, changing regime in a revised return:
• For non-business taxpayers, the regime choice is made in the return filed under Sec 139(1) (by the due date). A revised return under Sec 139(5) substitutes the original. Many practitioners and portal behaviour permit changing the regime in a revised return if the original was filed by the due date. CBDT FAQs indicate the option must be exercised in the 139(1) return, and a revised return (being a substitute) has been accepted by the utility for this.
• If the original was belated (139(4)), the old regime isn't available at all (the new regime is the default for belated returns).
• So if your original ITR was filed by the due date, you can generally revise it to the new regime within the revision window (31 December of the AY). Test with the utility.
