A charitabe institution registered u.s.12A. while filling ITR-7, "interest from bank FD" there are two schedules- AI and OS.to fill interest from bank FD.If I fill in Sch.OS, it is taken as fully taxable income at 30 % , but if I fill in sch.AI it is eligible for deduction under application of income. Why there is duplicate place for an income and which sch.is correct .kindly enlighten me.
