Thanks folks for the clarification. One more follow up: Even if portions of it are taxed at different rates, do capital gains still count as income, in the sense that they raise your AGI/MAGI? For example, if you were otherwise eligible to contribute to a Roth IRA, can having a lot of capital gains make you ineligible to contribute, if you had so much that it pushed your total over the income limit on Roth contributions? Does it similarly mess with everything else that depends on income such as child tax credits, ACA credits, college financial aid, the various education tax credits, the Earned Income Tax Credit, etc.?
