How it works

Long-term gains, on assets held more than a year, are taxed at 0%, 15% or 20%, depending on where they fall on top of your other taxable income. For 2026 the 0% rate covers taxable income up to $49,450 single or $98,900 joint, and 20% starts above $545,500 and $613,700.

Short-term gains are taxed as ordinary income. Above $200,000 of MAGI single ($250,000 joint), the 3.8% net investment income tax applies as well.
