The landscape of capital gains taxation changes every year, and 2026 brought adjustments to the income thresholds even though the headline rates remained the same. If you sell stocks, real estate, or other investments, it helps to know the difference between short-term capital gains and long-term capital gains, how the Net Investment Income Tax (NIIT) can apply, and which tactics can reduce your overall tax bill. This article summarizes the updated thresholds, defines the key terms, and walks through examples that clarify how your taxable gain is determined.
Below you’ll find the revised tax brackets for ordinary-income treatment of gains held one year or less, the stepped rates for long-term gains held more than a year, and special rules such as the higher rate on collectibles. Throughout the piece we use plain-language examples and practical planning moves like holding periods, tax-loss harvesting, and the use of automated advisors.

2026 rates and thresholds at a glance
Short-term gains are taxed as ordinary income using the same brackets as wages. For 2026 the marginal rates are 10%, 12%, 22%, 24%, 32%, 35%, and 37%. The income bands moved upward for inflation. For example, the 10% bracket applies to a single filer with taxable income from $0 to $12,400, while married couples filing jointly start at $0 to $24,800. At the top end, the 37% rate begins at $640,601 for single filers and $768,701 for married filing jointly. These brackets affect gains held for one year or less and other ordinary income together.
Long-term capital gains brackets
Assets sold after more than a year qualify for preferential long-term capital gains rates: 0%, 15%, and 20%. The 0% threshold for 2026 covers single filers with taxable income up to $49,450, married couples up to $98,900, and heads of household up to $66,200. Above those amounts the 15% bracket stretches until $545,500 for single filers ($613,700 married filing jointly), and the 20% rate applies beyond those higher thresholds. These banded rates mean your gain may be taxed at different percentages depending on the size of your ordinary income plus gains.
How gains, losses and additional taxes are calculated
Begin with the basics: a capital gain is the difference between an asset’s sale price and your adjusted basis. If you realize a profit in under one year, that profit is a short-term gain and is taxed at ordinary rates. If you hold the asset longer than a year, the profit is a long-term gain and benefits from the 0%/15%/20% structure. You can offset gains with capital losses first; if losses exceed gains you may deduct up to $3,000 of the excess against ordinary income ($1,500 if married filing separately) and carry any remaining loss forward to future years.
Example calculations
Imagine a single taxpayer with $40,000 in wages who realizes a $45,000 long-term gain. Combined taxable income is $85,000. Under 2026 thresholds the taxpayer will fall in the 15% long-term bracket for most of the gain, but if they had no other income the first portion of the gain would sit in the 0% band. Another common situation: short-term trading profits are simply added to wages and taxed at ordinary rates, so frequent traders often face higher effective tax rates on those realized gains.
NIIT, collectibles and other special rules
The Net Investment Income Tax (NIIT) is an additional 3.8% applied to certain investment income — including capital gains — when your modified adjusted gross income exceeds statutory thresholds. For 2026 the NIIT thresholds are $200,000 for single filers, $250,000 for married filing jointly, and $125,000 for married filing separately, among others. Separately, long-term gains on collectibles such as artwork, rare coins, and precious metals are taxed at a maximum 28%, regardless of regular long-term brackets.
Practical strategies to reduce capital gains taxes
Several techniques can lower your taxable gains. Holding an investment for more than one year converts potential short-term income into potentially lower-taxed long-term gains. Tax-loss harvesting—selling losing positions to offset winners—is another effective strategy; many robo-advisors provide automated harvesting that can be helpful for taxable brokerage accounts. Charitable donations of appreciated securities, timing sales into lower-income years, and using tax-advantaged accounts for active trading are other useful approaches.
Finally, coordinate with a tax professional before making major moves. Because your gains stack with other income to determine your bracket and NIIT exposure, year-round planning—rather than last-minute decisions—gives you the best chance to minimize taxes while meeting investment objectives.
