I am a salaried professional working in a software company.  I was also an LIC agent and i receive insurance commission as an income.

As i am working in a company I need to file ITR1 (income received under the head salary).

At the same time as I even receive insurance agent commission(after 10% TDS), I need to file ITR4.

Do I need to file both ITR1 and ITR4 returns? or shall i add both incomes and file as single ITR? If so which should I choose? Any help please...
