Long-term gains stack on top of your other income and are taxed at 0%, 15%, or 20% depending on your total taxable income.

Worth Knowing

The one-year holding period is the entire game here: sell an asset a day before its one-year anniversary and the gain is taxed as ordinary income at your regular bracket rate (see our Short-Term Capital Gains Tax Calculator); hold it one more day past that anniversary and it qualifies for these lower long-term rates instead, which top out at 20% even for high earners. Because long-term gains "stack" on top of your ordinary income to determine which bracket they fall into, a large one-time gain can push the rate on that specific gain higher even though your regular income tax brackets don't change.
