Capital gains taxes are among the most important tax considerations for high-net-worth investors and pre-retirees. Understanding current rates, who qualifies for each bracket, and how proposed law changes could affect your situation is essential for making informed decisions about when to sell investments, how to structure your portfolio, and how to plan around taxable events. At Q3 Advisors, we integrate capital gains planning into our broader Roth conversion and retirement income strategies for clients who want to minimize their lifetime tax burden.
Short-Term vs. Long-Term Capital Gains: The Basic Framework
The tax treatment of a capital gain depends primarily on how long you held the asset before selling it. Assets held for one year or less generate short-term capital gains, which are taxed at your ordinary income tax rate. For high earners, this can mean a federal rate of 32%, 35%, or 37%. Assets held for more than one year generate long-term capital gains, which are taxed at preferential rates of 0%, 15%, or 20%, depending on your taxable income.
The distinction matters enormously in practice. An investor in the 37% ordinary income bracket who sells a stock held for 13 months pays 20% federal capital gains tax. The same investor selling a stock held for 11 months pays 37%. Holding investments for at least one year before selling is one of the simplest tax-reduction strategies available, and it requires no special accounts or complicated planning, just patience.
2026 Long-Term Capital Gains Tax Rate Brackets
For 2026, the federal long-term capital gains tax rates and their corresponding taxable income thresholds are structured as follows. Note that these thresholds apply to long-term capital gains and qualified dividends, separate from your ordinary income tax brackets.

- 0% rate: For single filers with taxable income up to $49,450 and married filing jointly up to $98,900. Many retirees who have managed their income carefully can qualify for the 0% rate on a portion of their long-term gains.
- 15% rate: For single filers with taxable income between $49,451 and $545,500, and married filing jointly between $98,901 and $613,700. This bracket covers the majority of upper-middle-income investors and most high earners.
- 20% rate: For single filers with taxable income above $545,500 and married filing jointly above $613,700. This applies to the highest-income taxpayers and represents the top federal long-term capital gains rate under current law.
These thresholds are adjusted for inflation annually. State taxes on capital gains vary significantly by state, and some states tax capital gains as ordinary income, which can add another 5% to 13% depending on where you live. California, for example, taxes capital gains at ordinary income rates, making the combined federal and state burden over 33% for top earners in that state.
The TCJA Expiration and Potential Impact on Capital Gains
The Tax Cuts and Jobs Act of 2017 (TCJA) was made largely permanent by the One Big Beautiful Bill Act (OBBBA), signed into law on July 4, 2025. Most individual income tax provisions that had been scheduled to expire after December 31, 2025, including reduced ordinary income tax brackets, the increased standard deduction, and lower marginal rates, are now permanent. The long-term capital gains tax rates themselves (0%, 15%, 20%) were established prior to the TCJA and were never among the expiring provisions; they remain unchanged.
For high-income investors and retirees, this permanence is meaningful: the planning window for Roth conversions, capital gains harvesting, and income bracket management is no longer compressed by an impending tax law change. Strategies that work today are built on stable law rather than a temporary cliff. Our article on the 2026 estate tax exemption and OBBBA provides additional context on how the new law affects estate and gift planning.
Capital Gains and Roth Conversions: Strategic Planning Opportunities
For retirees and pre-retirees, the interaction between capital gains rates and Roth conversion planning creates important strategic opportunities. In years when you have low ordinary income (such as the gap years between retirement and the onset of Social Security or RMDs), you may be able to harvest long-term capital gains at the 0% rate while simultaneously executing Roth conversions at relatively low marginal tax rates. This combination is one of the most powerful tax minimization strategies available to pre-retirees.
For example, a married couple who retires at 62 and defer Social Security until 70 may have several years during which their taxable income is low enough to qualify for the 0% long-term capital gains rate. By carefully managing Roth conversions and capital gains harvesting in those years without crossing the threshold into the 15% capital gains bracket or triggering the Net Investment Income Tax, a couple can shift substantial wealth into tax-free status and eliminate taxable gains at zero cost. Working with an advisor who understands both capital gains and Roth conversion planning is essential to executing this strategy correctly. Learn how we approach this at Q3 Advisors’ Roth conversion services.
Net Investment Income Tax: An Additional Layer
In addition to the capital gains rates above, certain high-income taxpayers face the Net Investment Income Tax (NIIT), a 3.8% surtax on net investment income, including capital gains, dividends, interest, and rental income. The NIIT applies to the lesser of your net investment income or the amount by which your modified adjusted gross income exceeds $200,000 for single filers and $250,000 for married filing jointly.
When you add the 3.8% NIIT to the 20% top capital gains rate, the effective federal rate on long-term gains for the highest earners reaches 23.8%. Add state taxes and the all-in rate can easily exceed 30%. This makes careful asset location, holding period management, and tax-loss harvesting especially valuable for high-net-worth investors. In particular, holding appreciating assets in tax-advantaged accounts where capital gains are not recognized can significantly reduce this burden over time.
Capital Gains and Inherited Assets: The Step-Up in Basis Advantage
One of the most powerful capital gains planning tools available is the step-up in basis at death. When a taxable investment account passes to heirs, the cost basis of the inherited assets is stepped up to the fair market value as of the date of death, effectively wiping out all unrealized capital gains that accumulated during the original owner’s lifetime. This can eliminate millions of dollars of embedded capital gains for high-net-worth estates.
For assets with large unrealized gains held inside taxable accounts, this is a compelling reason to consider holding them until death rather than selling during life. Instead of selling appreciated stock to fund retirement expenses and paying capital gains tax, a pre-retiree might draw from tax-deferred accounts first, preserve the appreciated taxable assets for the step-up, and reduce the tax burden on heirs significantly. Our detailed guide on step-up in basis and estate planning explains how to incorporate this into your legacy strategy.
Frequently Asked Questions About Capital Gains Tax in 2026
Are capital gains taxed differently inside an IRA?
Yes. Inside a traditional IRA, all gains, including those that would otherwise qualify as long-term capital gains, are converted to ordinary income when the money is withdrawn. This means you lose the preferential long-term capital gains rates for investments held inside a traditional IRA. Inside a Roth IRA, qualified distributions are entirely tax-free, including all gains, regardless of how long the underlying investments were held.
What is the 0% capital gains tax rate threshold for 2026?
For 2026, the 0% long-term capital gains rate applies to taxable income up to $49,450 for single filers and $98,900 for married couples filing jointly. Taxable income includes ordinary income as well as the gains themselves, so careful management of all income sources is necessary to stay within the 0% bracket. Taxable income includes ordinary income as well as the gains themselves, so careful management of all income sources is necessary to stay within the 0% bracket.
How does the step-up in basis affect capital gains at death?
When you inherit taxable investment assets, the cost basis resets to the fair market value on the date of the original owner’s death, eliminating all previously unrealized gains from any capital gains calculation. If you inherit stock that your parent bought for $50,000 that is now worth $300,000, your basis is $300,000, and selling immediately triggers zero capital gains tax. This benefit is one of the most significant advantages of passing appreciated taxable assets to heirs rather than selling them during life.
Should I realize capital gains before the TCJA expires?
The TCJA provisions that once threatened to expire at end of 2025 were made permanent by the One Big Beautiful Bill Act, signed July 4, 2025. Capital gains rates themselves were never among the expiring provisions. The more relevant consideration now is whether your current tax bracket, IRMAA exposure, and estate planning goals favor realizing gains in a given year versus holding for the step-up in basis at death.
