NIIT is 3.8% of the lesser of net investment income or MAGI above $200,000 (single) / $250,000 (joint). Enter MAGI to calculate it; 0 other investment income is an explicit assumption. Real-estate professional status alone does not exempt gain. Missing required information is shown as “Not modeled.”
