If my self employment income is less than $400, do I still need to file schedule C?

[Marketstar]

If your self employment income of less than $400 was the only income you received in 2015, you are not required to file a return.

However, if you are otherwise required to file (see below), you should report the self employment income as the IRS expects taxpayers to report all taxable income.
