I am travelling on a US assignment from feb 17 to Jan 18. During this time I will be earning salary in India(TDS deducted) and monthly per diem for my expenses in US. This per diem will be paid through Forex card loaded from India. So once i return and encash the forex card(unspent per diem) will it be taxable. If yes, what happens if i withdraw the money in US and sent to an NRI account(if i am eligible to open one) or sent to my wife's or parents accounts ?
