Sir, 

Kindly tell me whether the IT is filed based on the gross income i.e, my only source of income is salary and no other income., or is is filed after deducting all my expenses like personal expenses, children care, rent, medicine etc.

Kindly help and tell the actual process... Also what is the minimum salary required to file and IT as per new assesment year???
