For federal tax purposes, a capital gain is generally short-term if the asset was held for one year or less before disposal, and long-term if held for more than one year. That classification follows the holding period, not how large the gain is or whether the seller calls the investment long-term. It also affects how gains and losses are combined for the year. Net short-term gains are treated as ordinary income, while net capital gains may qualify for different rates. Internal Revenue Service

Count the holding period

The Internal Revenue Service says the general rule is more than one year for long-term treatment and one year or less for short-term treatment. In counting, a taxpayer generally starts the day after acquiring the asset and counts through the day of disposal. The date of sale can therefore matter when it falls near the one-year mark. Internal Revenue Service

Imagine a hypothetical investor who buys one share lot on March 10 and disposes of it on March 9 of the following year. Under the general rule, that holding period is one year or less, so a gain or loss is short-term. If the investor instead disposes of the lot after more than a year has elapsed, the result is generally long-term. This example illustrates timing only; the source notes exceptions for certain property and interests. Internal Revenue Service

Classification is only the first step

The tax result is not determined by labeling each winning sale in isolation. The IRS describes net capital gain as the amount by which net long-term capital gain exceeds net short-term capital loss. Long-term gains are reduced by long-term losses, while short-term gains and losses also enter the yearly calculation. A gain that is long-term by holding period can therefore be part of a broader netting process. Internal Revenue Service

In a second hypothetical example, an investor sells one asset at a short-term gain and another at a long-term loss. The two labels remain different, but the year's overall result depends on how gains and losses are netted under the applicable rules. The distinction is useful because it tells the reader which category each transaction enters; it does not by itself state the tax due.

Why the tax treatment differs

The IRS states that net short-term capital gains are subject to ordinary income tax at graduated rates. Net capital gain may qualify for a lower rate than ordinary income, depending on taxable income and other rules. That difference is why the holding period can matter even when two assets produce gains of the same dollar amount. Internal Revenue Service

Federal income tax brackets work in layers: moving into a higher bracket does not mean the higher rate applies to all income, but only to the portion in that layer. The IRS page lists 2025 ordinary income rates, which are not a statement of current 2026 law. The comparison here is about the general distinction between ordinary income treatment and possible capital-gains rates, not a calculation using an outdated threshold. Internal Revenue Service

Keep the year and exceptions in view

The general holding-period rule has exceptions. The IRS points readers to separate rules for assets received as gifts or from a decedent, patent property, commodity futures and applicable partnership interests. The simple one-year comparison is therefore a useful starting point, not a complete rule for every kind of asset. Internal Revenue Service

Tax-year context also matters. The IRS capital-gains page gives rate thresholds for taxable years beginning in 2025, while the question of classification can arise in another year. A reader comparing transactions should identify the acquisition and disposal dates, determine whether a special rule may apply, and distinguish the holding-period label from the later calculation of net gains and applicable rates. The category explains timing; it does not alone answer the full tax question.
