📈 How Capital Gains Tax Works in 2026

Short-term capital gains (assets held 1 year or less) are taxed at your ordinary income tax rate — the same rate as your wages and business income. In 2026, these rates range from 10% to 37% depending on your income bracket.

Long-term capital gains (assets held more than 1 year) get preferential tax treatment. Depending on your total taxable income and filing status, your long-term gains are taxed at 0%, 15%, or 20%. This is why holding investments for more than a year can significantly reduce your tax bill.

Single: 0% up to $47,025  |  15% up to $518,900  |  20% over $518,900
Married Filing Jointly: 0% up to $94,050  |  15% up to $583,750  |  20% over $583,750
Head of Household: 0% up to $63,000  |  15% up to $551,350  |  20% over $551,350
• Your ordinary income is stacked first, then long-term gains are stacked on top to determine your rate.

Capital Gains Tax Calculator FAQ

Short-term capital gains come from assets held for 1 year or less and are taxed as ordinary income at your marginal tax rate (10–37% in 2026). Long-term capital gains come from assets held for more than 1 year and are taxed at preferential rates of 0%, 15%, or 20%, depending on your total taxable income and filing status.
For 2026, the 0% long-term capital gains rate applies to single filers with total taxable income up to $47,025, married filing jointly up to $94,050, and head of household up to $63,000. If your total income (including long-term gains) falls within these thresholds, you pay no tax on your long-term capital gains. This makes tax-loss harvesting and strategic selling especially valuable for taxpayers in lower brackets.
The holding period is the time you own an asset before selling it. The clock starts the day after you acquire the asset and ends on the day you sell it. If you hold for 1 year or less, any gain is a short-term capital gain taxed at ordinary income rates. If you hold for more than 1 year, it qualifies as a long-term capital gain taxed at 0%, 15%, or 20%. Selling on the one-year anniversary date counts as long-term since you held it more than one year (the day after acquisition plus one year).
Your ordinary income is stacked first, then long-term capital gains are stacked on top to determine your total taxable income. This total income determines which long-term capital gains bracket you fall into. For example, a single filer with $40,000 of ordinary income has $7,025 of headroom before reaching the 15% long-term gains bracket (which starts at $47,025 total income). Any long-term gains filling that headroom are taxed at 0%; gains above it are taxed at 15%.
For 2026, the long-term capital gains tax brackets are: 0% rate — single up to $47,025, married filing jointly up to $94,050, head of household up to $63,000; 15% rate — single $47,026 to $518,900, married filing jointly $94,051 to $583,750, head of household $63,001 to $551,350; 20% rate — single over $518,900, married filing jointly over $583,750, head of household over $551,350. These thresholds are adjusted annually for inflation.
Yes. If you have capital losses, you can use them to offset capital gains dollar-for-dollar. Short-term losses first offset short-term gains, then long-term gains. If your losses exceed your gains, you can deduct up to $3,000 ($1,500 if married filing separately) of net capital losses against your ordinary income each year. Any remaining losses carry forward to future years indefinitely. This strategy, known as tax-loss harvesting, is commonly used to reduce capital gains tax exposure.
If you sell your primary residence, you can exclude up to $250,000 of capital gains ($500,000 for married filing jointly) from tax, provided you have owned and lived in the home for at least 2 of the last 5 years (the 2-out-of-5-year rule). This exclusion can be used once every 2 years. Any gain above these limits is taxed as a long-term capital gain at the applicable rate based on your income.
In most states, capital gains are taxed as ordinary income at the state level using the same rates as your regular income. States like California tax capital gains at high marginal rates (up to 13.3%). States with no income tax — Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming — do not tax capital gains at the state level. A few states like New Hampshire only tax interest and dividend income, not capital gains.

Understanding Capital Gains Taxes in 2026

A capital gain is the profit you make when you sell an asset for more than you paid for it. The US tax system treats these gains differently depending on how long you held the asset and your total income for the year. Understanding these rules can help you keep more of your investment returns.

Short-Term vs Long-Term Capital Gains

The most important distinction in capital gains taxation is the holding period. Assets sold within one year of purchase generate short-term capital gains, which are taxed at your regular income tax rates — the same brackets that apply to your wages, business income, and other ordinary income. In 2026, these rates range from 10% to 37%.

Assets held for more than one year qualify for long-term capital gains treatment, with significantly lower tax rates of 0%, 15%, or 20%. This preferential treatment is designed to encourage long-term investing and provides a substantial tax advantage for patient investors.

2026 Capital Gains Tax Rates

For the 2026 tax year, the long-term capital gains tax brackets have been adjusted for inflation. The 0% rate applies to single filers with income up to $47,025, married couples filing jointly up to $94,050, and heads of household up to $63,000. The 15% rate covers income up to $518,900 (single), $583,750 (married), and $551,350 (head of household). Above those thresholds, gains are taxed at 20%.

Additionally, high-income taxpayers may be subject to the 3.8% Net Investment Income Tax (NIIT) on the lesser of their net investment income or the amount their modified adjusted gross income exceeds $200,000 (single) or $250,000 (married filing jointly).
