Need to file nil itr?

Hello,

I am an individual aged 23 years. I had filled ITR for two years until last year(it includes tds as I worked as a consultant). In March 2013, I left my job to pursue higher studies. I have had no income in the past year (FY 13-14).

So, is it necessary to file ITR this year? If not, is there any other step to be taken? 

Thank you very much.
