Capital Gains Tax Guide 2026: Short-Term vs Long-Term Rates

What Are Capital Gains?

A capital gain is the profit you realize when you sell a capital asset for more than its cost basis. Your cost basis is generally the purchase price plus any transaction costs, improvements (for real estate), or reinvested dividends (for investments). The gain is the difference between your selling price and your adjusted cost basis.

Capital gains are not taxed until you sell the asset and realize the gain. Unrealized gains, meaning assets that have increased in value but have not been sold, are not subject to income tax. This is known as the realization principle, and it is one of the most important concepts in tax planning because it means you control when you trigger a taxable event.

Conversely, a capital loss occurs when you sell an asset for less than your cost basis. Capital losses can offset capital gains dollar for dollar, and up to $3,000 of net capital losses can be deducted against ordinary income each year. Excess losses carry forward to future tax years indefinitely. Use our Income Tax Calculator to model how capital gains affect your total tax liability.

Short-Term vs Long-Term: The Holding Period Rule

The IRS divides capital gains into two categories based on how long you held the asset before selling:

• Short-term capital gains: Assets held for one year or less. These are taxed as ordinary income at your marginal tax rate, which can be as high as 37%.
• Long-term capital gains: Assets held for more than one year (at least one year and one day). These receive preferential tax rates of 0%, 15%, or 20% depending on your taxable income.

The holding period begins the day after you acquire the asset and includes the day you sell it. For example, if you buy stock on January 15, 2025, you must hold it until at least January 16, 2026, for it to qualify as a long-term gain. Selling on January 15, 2026, would still be short-term. Understanding how tax brackets work is essential since short-term gains stack on top of your ordinary income.

2026 Long-Term Capital Gains Tax Rates

Long-term capital gains rates depend on your taxable income and filing status. These thresholds are adjusted annually for inflation:

The 0% rate is particularly powerful. A married couple filing jointly with $96,700 or less in taxable income pays zero federal tax on their long-term capital gains. This creates significant planning opportunities, especially in retirement when income may be lower.

Short-Term Capital Gains Tax Rates

Short-term capital gains do not receive any preferential treatment. They are added to your ordinary income and taxed at your regular marginal rate. For 2026, the ordinary income tax brackets range from 10% to 37%:

The difference between short-term and long-term rates can be dramatic. A single filer earning $200,000 with a $50,000 capital gain would pay $16,000 in tax on a short-term gain (32% marginal rate) but only $7,500 on a long-term gain (15% rate). That is an $8,500 savings simply for holding the asset longer than one year.

Net Investment Income Tax (NIIT)

High-income taxpayers face an additional 3.8% Net Investment Income Tax (NIIT) on the lesser of their net investment income or the amount by which their modified adjusted gross income (MAGI) exceeds the following thresholds:

• Single / Head of Household: $200,000
• Married Filing Jointly: $250,000
• Married Filing Separately: $125,000

This means the maximum federal rate on long-term capital gains is effectively 23.8% (20% + 3.8% NIIT) for the highest earners. For short-term gains, the combined rate can reach 40.8% (37% + 3.8% NIIT). These NIIT thresholds have not been adjusted for inflation since 2013, which means more taxpayers are subject to this surtax each year.

Home Sale Exclusion: The $250K/$500K Rule

One of the most generous capital gains exemptions is the primary residence exclusion under Section 121. If you sell your primary home and meet the ownership and use tests, you can exclude up to $250,000 in capital gains ($500,000 for married couples filing jointly) from taxation.

To qualify, you must have owned and used the home as your primary residence for at least two of the five years preceding the sale. You can use this exclusion once every two years. Any gain exceeding the exclusion amount is taxed as a capital gain at either short-term or long-term rates depending on your total ownership period.

If you are selling your home, our guide on tax implications of selling your home covers the exclusion rules, cost basis adjustments, and partial exclusion scenarios in full detail. You can also use our Property Tax Calculator to estimate ongoing property taxes on a new home.

Capital Gains on Real Estate Investments

Investment properties do not qualify for the Section 121 exclusion, but real estate investors have other powerful tools available. Depreciation recapture is taxed at a flat 25% rate on the portion of the gain attributable to depreciation deductions taken during ownership. The remaining gain above the depreciated basis is taxed at long-term capital gains rates.

A 1031 like-kind exchange allows you to defer capital gains tax entirely by reinvesting the proceeds into a replacement property of equal or greater value. This strategy can be repeated indefinitely, allowing real estate investors to defer gains across decades of property transactions. Learn the full rules in our 1031 Exchange guide.

When planning a property sale, use our Income Tax Calculator to model how the capital gain will interact with your other income and determine your effective tax rate on the transaction. If you have a mortgage on the property, our sister site Amortio can help you calculate remaining loan balances and payoff scenarios.

Tax-Loss Harvesting Strategy

Tax-loss harvesting is the practice of selling investments at a loss to offset capital gains realized elsewhere in your portfolio. This strategy can eliminate capital gains taxes entirely in some years and carry forward excess losses to reduce future tax bills.

The key rules to remember are: short-term losses offset short-term gains first, long-term losses offset long-term gains first, and then net losses of either type can offset gains of the other type. Up to $3,000 in net capital losses can offset ordinary income annually. The wash sale rule prohibits claiming a loss if you repurchase a substantially identical security within 30 days before or after the sale. Read our comprehensive Tax-Loss Harvesting Guide for detailed strategies and examples.

Capital Gains on Cryptocurrency

Cryptocurrency is treated as property by the IRS, not as currency. Every sale, trade, or exchange of crypto triggers a taxable event. This includes trading one cryptocurrency for another, using crypto to purchase goods or services, and receiving crypto as payment for work. The same short-term and long-term holding period rules apply.

Starting in 2026, crypto exchanges are required to issue Form 1099-DA reporting your transactions to the IRS. This makes accurate record-keeping more important than ever. Each transaction must track the cost basis and holding period of the specific coins sold. Most crypto tax software uses specific identification (choosing which lots to sell) to minimize gains, but the default IRS method is FIFO (first in, first out). See our Crypto Tax Reporting Guide for complete details.

Strategies to Minimize Capital Gains Tax

Several legitimate strategies can reduce or defer your capital gains tax liability:

1. Hold for more than one year. The simplest and most effective strategy. Moving from short-term to long-term rates can cut your tax rate in half or more.
2. Harvest losses. Sell underperforming investments to offset gains elsewhere in your portfolio. Carry forward unused losses indefinitely.
3. Use the 0% rate bracket. Time asset sales for years when your taxable income is low enough to qualify for the 0% long-term rate.
4. Donate appreciated assets. Donating stocks or other assets held over one year to charity allows you to deduct the full market value without paying capital gains tax on the appreciation.
5. Invest in Opportunity Zones. Qualified Opportunity Zone investments can defer and partially exclude capital gains.
6. Use retirement accounts. Investments within 401(k)s, IRAs, and HSAs grow tax-free. No capital gains tax applies until withdrawal (or ever, for Roth accounts).
7. Step-up in basis at death. Inherited assets receive a stepped-up cost basis to fair market value at the date of death, eliminating all unrealized capital gains.

State Capital Gains Taxes

In addition to federal taxes, most states also tax capital gains. Nine states have no income tax and therefore no state capital gains tax: Alaska, Florida, Nevada, New Hampshire (interest and dividends only through 2026), South Dakota, Tennessee, Texas, Washington (though a 7% surcharge on long-term gains over $270,000 applies), and Wyoming.

Most states tax capital gains as ordinary income, with top rates ranging from about 3% (North Dakota) to 13.3% (California). Combined with the maximum federal rate of 23.8%, a California resident could face a total capital gains tax rate of 37.1% on long-term gains.
