What Is Capital Gains?
Capital gains are profits from selling an investment for more than you paid. Learn short-term vs long-term capital gains tax rates and strategies to minimize taxes.
Definition
A capital gain is the profit you realize when you sell an investment (stock, bond, real estate, or other asset) for more than you paid. If you bought a stock at $50 and sell it at $80, your capital gain is $30 per share. Capital gains are only "realized" (and taxed) when you actually sell. An unrealized gain is a profit on paper that you have not yet locked in.
Capital gains are taxed at different rates depending on how long you held the asset. Short-term capital gains (assets held one year or less) are taxed at your ordinary income tax rate, which can be as high as 37%. Long-term capital gains (assets held longer than one year) are taxed at preferential rates: 0%, 15%, or 20%, depending on your income level.
The tax difference between short-term and long-term is significant. For someone in the 32% tax bracket, selling a $10,000 gain after 11 months costs $3,200 in taxes. Waiting one more month to qualify for long-term treatment reduces the tax to $1,500 (15% rate). This single timing difference saves $1,700.
Real-World Example
You buy 200 shares of a stock at $40 per share ($8,000 total). Fourteen months later, you sell all 200 shares at $60 per share ($12,000 total). Your capital gain is $4,000. Because you held the shares for more than one year, this qualifies as a long-term capital gain. If your income puts you in the 15% bracket, you pay $600 in capital gains tax. If you had sold at 11 months instead of 14, the same $4,000 gain would be taxed at your ordinary rate -- potentially $1,000 to $1,480 depending on your bracket.
Why It Matters
Understanding capital gains is essential for tax-efficient investing. Many investors unknowingly pay thousands more in taxes than necessary by selling holdings before the one-year mark. Tax-loss harvesting (selling losers to offset gains), holding investments long-term, and using tax-advantaged accounts (401(k), Roth IRA) are all strategies that leverage capital gains rules. The difference between tax-aware and tax-ignorant investing can add up to hundreds of thousands of dollars over a lifetime.

Frequently Asked Questions
How much is capital gains tax?
Long-term capital gains (held over 1 year) are taxed at 0%, 15%, or 20% depending on income. Short-term gains (held 1 year or less) are taxed at your ordinary income rate, which ranges from 10% to 37%.
Can I avoid capital gains tax?
You can minimize capital gains by holding investments for over a year (long-term rates), using tax-advantaged accounts, tax-loss harvesting, or donating appreciated assets to charity. In a Roth IRA, there is no capital gains tax at all.
What is the difference between realized and unrealized capital gains?
A realized gain occurs when you sell an asset for a profit. An unrealized gain is a profit that exists on paper but has not been locked in by selling. You only pay taxes on realized gains.
Do I pay capital gains on my home?
If you sell your primary residence, you can exclude up to $250,000 in gains ($500,000 if married) from capital gains tax, as long as you lived in the home for at least 2 of the last 5 years.
