Simple definition
A long-term capital gain is the profit you make when you sell an asset — like a stock or fund — that you held for more than a year. Because you held it longer, the profit is taxed at special long-term rates of 0%, 15%, or 20%, which are generally lower than the rates on wages or short-term gains. Picture patience earning you a tax discount on your profit.
Why it matters
The lower long-term rates can save you a meaningful amount compared with selling too quickly. Holding an investment past the one-year mark before selling is one of the simplest ways to keep more of your gains, which matters a lot for long-term investors.
Real-life example
Suppose you buy $10,000 of an index fund and sell it two years later for $14,000, a $4,000 gain. Because you held it more than a year, that $4,000 is a long-term capital gain, taxed at the 0%, 15%, or 20% rate that applies to you rather than your ordinary income rate.
Common mistakes
- Selling just before the one-year mark and losing the lower rate.
- Confusing long-term with short-term gains, which are taxed as ordinary income.
- Forgetting that gains are only taxed when you actually sell.
- Ignoring that losses can offset gains and lower your taxable total.
Pro tips
- Hold appreciated assets more than a year to qualify for long-term rates.
- Track your purchase date and cost basis for every investment.
- Consider harvesting losses to offset some gains in the same year.
- Coordinate large sales across tax years to manage your rate.

Frequently asked questions
What counts as long-term?
You must hold the asset for more than one year before selling. Hold it a year or less and the profit is a short-term gain, taxed at your ordinary income rate instead of the lower long-term rates.
What are the long-term capital gains rates?
Long-term gains are taxed at 0%, 15%, or 20%, depending on your income. These are generally lower than ordinary income tax rates, which is why holding investments past a year can reduce the tax on your profit.
When do I owe the tax?
Only when you sell and realize the gain. An investment that rises in value is not taxed while you still hold it. Selling at a profit triggers the capital gain and the tax that goes with it.
Knowing what Long-Term Capital Gains means is knowledge — the first half. A brick gets placed when you act on it: check your purchase date before selling so you know if a gain is long-term.
