Capital Gains Taxes, Explained for Everyday Investors

As more Americans invest through brokerage accounts, understanding how capital gains are taxed has become a mainstream concern rather than a niche one. The basics are straightforward and worth knowing.

A capital gain is the profit from selling an asset for more than you paid. The tax depends heavily on how long you held it: assets held longer than a year qualify for lower long-term rates, while shorter holdings are taxed as ordinary income.

Timing matters

That distinction creates a simple planning lever. Holding an appreciated asset past the one-year mark can substantially reduce the tax on the eventual sale. Rushing a sale just before the anniversary can be a costly mistake.

Losses can offset gains, and a limited amount of net loss can offset ordinary income, with the rest carried forward. Harvesting losses late in the year to offset gains is a common, legitimate strategy, subject to rules against immediately repurchasing the same security.

In tax-advantaged accounts

Gains inside retirement accounts are not taxed as they occur, which is much of their appeal. Keeping frequently traded positions in such accounts, and long-term holdings in taxable ones, is a rough rule of thumb many investors follow.
