I got retired from a nationalised bank on 31.10.2017. I received a gratuity amount of Rs.14.50 lacs. As per the income tax
rules prevailing at that time, the gratuity beyond Rs.10.00 lacs (i.e., Rs.4.50 lacs) was taxed. Now since the notification dated
29.3.2018 increased this exemption limit to Rs.20 lacs, am I eligible to claim the refund of tax paid by me on Rs.4.50 lacs?
