Thanks for your reply, Firstly I beg your pardon that I have wrongly mentioned the Assesment year, infact it was financial year 2009-10. I have been told by our auditors that tax deducted on 31 march 2010 can be deposited up to 31/05/2010 without any panelty intt. If it was so, than why IT officer demanding for late payment intt. pls guide
