Thanks for the info. In the IRS answers it specifically says wages and social security are not part of NIIT, but in the worksheet you included it does include them. In the Turbotax notes on line 13 on 8960 where it says what is included, it does not say wages or social security. The fact that this is supposed to be an additional tax for high INVESTMENT income individuals, combined with the IRS answers about it, makes me wonder if the intent is being wrongly calculated in the worksheet?
