How it works

How long you hold an investment changes the tax dramatically. Assets held over a year qualify for preferential long-term rates of 0%, 15%, or 20% based on income; sell sooner and the gain is taxed as ordinary income at your regular bracket.

Frequently asked questions

How do I get the 0% long-term rate?

If your total taxable income (including the gain) stays under roughly $48,000 single or $97,000 married for 2025, long-term gains in that range are taxed at 0%. It’s why timing a sale to a low-income year can pay off.
