How capital gains tax works in Florida
Long-term gains (assets held more than a year) get the federal 0/15/20% rates — but the rate depends on where the gain lands once it is stacked on top of your other taxable income, so part of a gain can be taxed at 0% and the rest at 15%. Short-term gains are taxed as ordinary income. On top of that, the 3.8% Net Investment Income Tax applies once your income clears $200,000 (single) or $250,000 (married-jointly).
