I am contract basis faculty in govt. orgnaisation from 2011. The institute has deducted the TDS from 2011 up to 2016 and issued form no. 16a. In April 2016 we have file a petition high court regarding regularisation. From April 2016 we are working due to court direction on the same payment. From FY 2016-17 they had not deducted the tax and not giving the form no 16a.
