My son submitted his PHD thesis in April 2017 and from May to mid September worked as an intern from which he earned Rs 2,54,000 ( per month RS 60,000 ). In October he went to US for post doctoral reasech and gets around $ 3,500 ( after paying dual tax there ) per month .
My question is whether he has to pay the tax in India for the finanacial year 2017-18 and if he has to then what will be the sum and why ?
NB : He has two insurance polices for which he pays Rs 25000 and Rs 16000 per annum as premium and has no other investment.
