When you sell an investment for more than you paid for it, the profit is called a capital gain. It is one of the most basic concepts in investing, and understanding how capital gains are taxed can save you real money.
How Capital Gains Work
You buy 10 shares of a company at $50 each ($500 total). Later, you sell all 10 shares at $80 each ($800 total). Your capital gain is $300 ($800 - $500).
You only realize a capital gain when you actually sell. If the stock goes up but you do not sell, that is an unrealized gain (sometimes called a "paper gain"). You do not owe taxes on unrealized gains.
Short-Term vs Long-Term
The tax rate on your capital gain depends on how long you held the investment:
Short-term capital gains (held less than 1 year) are taxed as ordinary income. That means they are taxed at your regular income tax rate, which could be 22%, 24%, 32%, or higher depending on your bracket.
Long-term capital gains (held 1 year or longer) receive preferential tax rates: 0%, 15%, or 20% depending on your taxable income. For most people, this means 15%.
The difference is significant. If you are in the 24% tax bracket, a short-term gain costs you $72 in taxes per $300 gain. A long-term gain costs you $45. That is a 37% difference in tax just from holding an extra few months.
Capital Losses
If you sell an investment for less than you paid, that is a capital loss. Losses can offset gains, reducing your tax bill.
If your total capital losses exceed your total capital gains in a year, you can deduct up to $3,000 of the excess against your ordinary income. Any remaining losses carry forward to future years.
Tax-Loss Harvesting
Some investors intentionally sell losing positions to realize capital losses, then use those losses to offset gains. This strategy is called tax-loss harvesting and can reduce your annual tax bill.
However, the wash-sale rule prevents you from buying back a substantially identical investment within 30 days before or after the sale. If you do, the loss is disallowed for tax purposes.
How to Minimize Capital Gains Taxes
Hold for at least one year to qualify for long-term rates.
Use tax-advantaged accounts (401(k), IRA, Roth IRA) where capital gains are either tax-deferred or tax-free.
Be strategic about selling. If you have gains and losses in the same year, consider selling both to offset.
Do not let taxes drive your investment decisions. Paying 15% tax on a profit is better than avoiding taxes by holding a position you no longer believe in.
