An assessee has earned interest on bank Fixed Deposit around INR 1,00,000 in FY 2017-18. He submitted Form 15G so no TDS was deducted by the bank. This interest income is mentioned in Form 26AS as income and no tax deduction. Now while filing ITR this income is to be shown as "Income from Other Sources". Tax is being charged on this interest income for which Form 15G is already submitted.
How can he claim tax exemption on this interest income while filing ITR? Or is this income fully taxable?
