Answer:
Angela's additional tax liability will be $0 in this case
Step-by-step explanation:
As Angela is married and filing separately, she will be subject to the Additional Medicare Tax if her self-employment income exceeds $125,000.
The Additional Medicare Tax is 0.9% of wages, self-employment income, and railroad retirement (tier 1) benefits that exceed $200,000 for individuals who file as married filing separately.
Therefore, if Angela has no wage income and $200,000 in earnings from self-employment, her Additional Medicare Tax liability would be:
0.9% x ($200,000 - $200,000) = $0
