Hi Pankaj, For the AY 2013-13 my employer consistently deducted TDS from my salary and I was provided a form 16 in June last year basis which I filed my returns. Last week I recieved a communication from Income Tax where they had indicated that the tax calculated for my income still remains due and had shown 0 (zero) Rs as tax deducted at source. I have been asked to respond in 30 days. Could you please help me understand how should I reply to this, what documents as proof do I need to obtain from my employer. Also I have left that job and am working with a new employer now.
