If an individual has income from investments, the individual may be subject to net investment income tax. Effective Jan. 1, 2013, individual taxpayers are liable for a 3.8 percent Net Investment Income Tax on the lesser of their net investment income, or the amount by which their modified adjusted gross income exceeds the statutory threshold amount based on their filing status.
The statutory threshold amounts are:
- Married filing jointly — $250,000,
- Married filing separately — $125,000,
- Single or head of household — $200,000, or
- Qualifying widow(er) with a child — $250,000.
If I make more than 200,000 and some of it is investment income, then MAGI (which includes social security) is used to determine how much income is taxed.
The tax helps pay for Affordable Healthcare Act.
