Self employed

Your net income is too low to have any personal income tax.  The self employment tax is the Net Profit 13,728 x .9235 = 12,678.    Then 12,678 x .153 = $1,940 self employment tax.

 

I don't understand what you are saying about the Tesla only earned 31,838?  How many businesses do you have?  Isn't it all on one Schedule C?
