Do i need to file IT return for my pvt ltd company ?

Every company shall furnish the return of income electronically under digital signature. In other words, for corporate taxpayer e-filing with digital signature is mandatory.

Thanks Deepak,

One more query is since my company was incorporated on 5.02.2016 only and no transactions happened yet when should I file IT return and how to do it on myself, please suggest what to do in my case if u can ?

for a private limited company, chartered accountant certification is must, 

get in touch with your CA, he might add the previous months and would file the return for 14 months consollidated, 

though as per IT rules you had to file 14-15 also
