What is Capital Gain?

A capital gain is the profit you make when you sell an asset for more than you paid for it. An asset's value appreciation is considered an 'unrealized' gain until it is sold, at which point it becomes a 'realized' gain subject to taxation.

Capital gains are divided into short-term and long-term based on the holding period. Short-term capital gains apply to assets held for one year or less and are taxed as ordinary income. Long-term capital gains apply to assets held for more than one year and are taxed at lower rates (0%, 15%, or 20%).

Under IRS rules, capital gains can be offset by capital losses (selling assets at a loss), a strategy known as tax-loss harvesting. Realized capital gains must be reported on tax returns, making tax optimization a key consideration in portfolio management.

PRACTICAL EXAMPLE

An investor purchases shares of stock for $5,000. After holding them for 18 months, they sell the shares for $8,005. The investor realizes a $3,000 long-term capital gain, which is subject to a 15% tax rate ($450) for most income brackets.
