Filing of return

You have to give a representation with your local CIT.

Local CIT means jurisdictional or place of stay at present

You can contact your AO and give a request for condonation of delay under 119[2b] for AY 12-13 [FY 11-12]  For AY  [13-14] you can file belated return online till March 31 2016 under  139[4]. Was your  taxable income less in  FY11-12? 

.

Ya income credited was 297275 tds deducted is 29728

This is above taxable income - so you should have filed return

Now give an apllication to AO with copy to CIT of your present ward

Sir

Am i not eligable for basic exemption limit..and under what head i will be taxable 

Since you were taxed [TDS] under 194J. it is profesional fees.

You can prepare a simple P&L and balance sheet.  

You have to file ITR-4 since it is professional fees.

I hope i am clear 

I worked in TCS but i will get salary from contractor even in 26as it shows contractor name

Since 26AS shows TDS deducted under  194J - it means you have been paid Fees [not salary]  on contract basis. If this is not correct then you have to tell your Contractor to rectify his TDS return and correct to 192 from 194J. 

If he is not willing to change then you have to file return as biz/professional income 

You have to file ITR-4 . i hope iam crystal clear on this.

Ya thank you so much..
