For last two financial years my salary comes under taxable range ie. 2.5L but after the deductions like insurance,PPF etc I wouldn't have to pay any tax as per Form 16 from my company. I also have PAN but not filed any ITR yet eventhough my salary is withing taxable range without deductions. So, is it compulsary to file ITR if salary is with in taxable limit but not taxable after deductions? If yes, can I file ITR a fresh from this FY only, or should sumbit the same for last two years also? Please help.
