Capital Gains Taxes

The plain answer

A capital gain is the profit you realize when you sell an investment for more than its tax basis. You generally owe tax on the gain, not on the full sale price.

How long you held the investment matters. A gain from an asset held for one year or less is generally short term and taxed like ordinary income. A gain from an asset held for more than one year is generally long term and uses the long-term capital-gains schedule. See Short-Term vs. Long-Term Capital Gains for the holding-period basics.

How it actually works

Start with the amount you received from the sale, then subtract your adjusted tax basis and eligible selling costs. Your basis usually starts with what you paid, but reinvested distributions, fees, stock splits, and other adjustments can change it.

For 2026, a single filer can have taxable income up to $49,450 within the zero-rate long-term capital-gains band. The next band extends through $545,500 of taxable income. Filing status changes these thresholds, and the gain stacks on top of your other taxable income. Crossing a threshold does not cause every dollar of gain to move into the higher band.

Capital losses can offset capital gains. If losses exceed gains, part of the remaining loss may offset other income, and unused losses may carry forward. The details depend on the transactions and your tax return.

What this means for you

Before selling, check your holding period, expected gain, tax basis, and total taxable income for the year. A sale near the one-year mark can have a different tax result depending on which side of the holding-period rule it falls.

Taxes belong in the decision, but they should not control it. Do not spend a dollar to save thirty cents in taxes. Selling can still make sense when an investment no longer fits your plan, creates too much concentration, or funds a higher-priority goal.

Common mistakes

• Treating the entire sale price as taxable gain.
• Assuming every investment profit receives long-term treatment.
• Reading a threshold as though one extra dollar changes the rate on the entire gain.
• Forgetting that reinvested distributions can increase basis.
• Holding a risky or unsuitable investment only to avoid tax.
