Assessee had not filed Income tax return for the F.Y. 2017-18 on which there was a certain amount of TDS deducted. Assessee enjoys exemption on entire taxable income u/s 10(26) and hence there is no tax payable in assesse's case. Can this unclaimed TDS be shown in the return of F.Y. 2018-19 and the refund be claimed. If so, will that make the assessee more susceptible to receiving notice by the Income tax Department.
