Plasma Donations and Self Employment

[sven_the_huge]

So my main question is that my son is a graduate student without much income.   Let's call it $2500.  He also did plasma donations in the amount of $1800.   I know that plasma donation payments are taxable income - but since it is greater than $400 - does he now have to play self-employment taxes on it?

That has been debated on this site and the question is whether he does it often enough to be considered as having a business. The amount of income you posted would, I think, be considered other or miscellaneous income and could skirt the self employment tax. Others may differ.
