Capital gains tax is the tax on profits from selling an asset for more than you paid for it. The tax rate depends on how long you held the asset and your taxable income level.
Long-term capital gains (assets held more than one year) are taxed at preferential rates: 0%, 15%, or 20%, depending on your income. Short-term capital gains (assets held one year or less) are taxed as ordinary income at your regular tax bracket rate.
For 2024, single filers pay 0% on long-term gains if taxable income plus gains is below $47,025, 15% up to $518,900, and 20% above that. High-income taxpayers may also owe the 3.8% Net Investment Income Tax (NIIT). Strategic use of holding periods and tax-loss harvesting can significantly reduce capital gains tax liability.
