Not all capital gains are taxed the same way. Whether a gain is classified as short-term or long-term can change the tax rate applied to it substantially, sometimes by 15 percentage points or more. Understanding this distinction, and the rules around it, is one of the simplest ways an investor can think through the tax impact of a large sale before it happens.
The One-Year Rule: What Counts as Short-Term vs. Long-Term
An asset held for one year or less before being sold generally produces a short-term capital gain. An asset held for more than one year, meaning at least one year and one day, produces a long-term capital gain. The holding period is counted starting the day after the asset was acquired. A common mistake is counting the purchase date itself as day one; selling exactly one year after purchase still results in short-term treatment. Getting this date right can be the difference between two very different tax outcomes.
Short-Term Capital Gains Tax Rates
Short-term capital gains are taxed as ordinary income, using the same federal brackets that apply to wages, up to a top rate of 37% for the highest earners. There is no preferential rate for short-term gains, regardless of the type of asset sold.
Long-Term Capital Gains Tax Rates
Long-term capital gains are taxed at preferential federal rates of 0%, 15%, or 20%, depending on taxable income and filing status. Higher earners may also owe an additional 3.8% Net Investment Income Tax on top of the capital gains rate. Because bracket thresholds are adjusted periodically, current-year figures should be confirmed with a tax professional rather than assumed from a prior year.
Side-by-Side Example: Same Gain, Different Holding Period
Consider an investor who realizes a $200,000 gain. If the asset was held for eleven months, the entire gain is taxed at ordinary income rates, which could mean a significant federal tax bill for a high earner. If the same asset were held for thirteen months instead, the gain would qualify for long-term treatment, taxed at a maximum federal rate of 20% plus the 3.8% surtax for high earners, a meaningfully lower total. In many cases, waiting a matter of weeks to cross the one-year mark can make a substantial difference in the tax owed.
Special Cases
A few categories of gains fall outside the standard short-term and long-term framework. Collectibles, such as art, coins, and certain precious metals, are subject to a maximum long-term rate of 28%. Depreciation recapture on real estate is taxed at up to 25%, separately from the remaining gain, which is taxed at standard long-term rates.

Why This Matters More for Large, Concentrated Gains
Timing a sale to cross the one-year holding period is a straightforward way to manage the tax impact of a moderate gain. But once a gain reaches a certain size, whether from a business sale, a large real estate transaction, or a concentrated stock position, the difference between short-term and long-term rates, while still meaningful, may not go far enough on its own. At that point, deferral strategies such as a Deferred Sales Trust are worth exploring alongside, or instead of, simply timing the sale.
