Deductions & credits

NotLearnedHand,

 

There are several questions you pose.

 

(1) Is money reported via 1099-NEC self-employment income?  Answer: yes.  See https://www.irs.gov/government-entities/indian-tribal-governments/itg-faq-2-answer-what-income-is-co... 

(2) What is the standard deduction of a dependent?  Answer: the maximum of $1,100 or (earned income + $350) but no more than $12,550. Also, the IRS instructions for form 1040 states:

 

You must file a return if any of the following apply.
Your unearned income was over $1,100.
Your earned income was over $12,550.
Your gross income was more than the larger of—
$1,100, or
Your earned income (up to $12,200) plus $350

 

Do taxpayers with self-employed income owe self-employment tax?  Answer: yes if net self-employment earnings are at least $400.  This is the government's way of collecting social security and medicare tax on all earned income.  If your son had gotten a W-2, it would show those taxes taken out of his gross pay.  Being self-employed, he has to cough up the equivalent, actually twice as much because he pays both the employee and employers share.

 

Bottom line: From the information you have provided, TurboTax has followed the correct procedure.  It also subtracts half of that self-employment tax from his income, a small gesture, to be sure.
