Till today, that I know,the Income Tax of an incumbent (in case of school) deducted from his/her salary and deposited to the office by the D.I. The school authority is bound to do so. After that the H.M./Secretary will give the Form-16 to the teachers and other staff.Now getting the From 16,personally or on line it may submitted to the authority. No school teachers or other staff of the aided school can submit their income tax personally. Thank you.
