Can a government salary employee carry a proprietary business? Which ITR form should he fill out?

Hi sir,

There is a restriction on government employees to carry proprietary business. I will suggest you start your business under any other person's name.
Further, the ITR return form shall be ITR 3 for FY 2016–17. Which is required for business or professional incomes along with salary incomes. If you have only salary income, file it in ITR-1

Hope it is useful.
