Long-Term Capital Gains Rates: The Tax Advantage of Patience

When you sell an investment held for more than one year, you qualify for long-term capital gains rates—the most favorable tax treatment available to individual investors. These rates are dramatically lower than ordinary income tax rates, ranging from 0% to 20% at the federal level, depending on your income level. This preferential treatment is Congress's way of rewarding patient, long-term investing and is one of the most powerful wealth-building incentives in the entire tax code.

Quick definition: Long-term capital gains are profits from assets held over one year. They're taxed at preferential rates (0%, 15%, or 20%) much lower than ordinary income rates (10%–37%).

Key takeaways​

  • Long-term gains are taxed at just 0%, 15%, or 20% federally—no higher rates regardless of income
  • A high-income investor in the 37% ordinary income bracket pays only 20% on long-term gains—a 46% tax reduction
  • Long-term capital gains have their own separate tax brackets, unlike short-term gains that are added to ordinary income
  • Most investors (those earning <$583,750 if married) pay 15% or less on long-term gains, regardless of how high their income is
  • The 0% rate is available to lower-income investors and is one of the best-kept secrets in tax planning
  • International investors should note: many countries offer similar preferential long-term rates, but the U.S. rates are particularly generous

The Three Long-Term Capital Gains Tax Brackets​

For 2024–2025, as of the mid-2020s, the federal tax rate on long-term capital gains depends on your taxable income:

0% Rate (No Federal Tax)​

Single Filers: Taxable income up to approximately $47,025 Married Filing Jointly: Taxable income up to approximately $94,050

If your total taxable income (including long-term gains) falls below these thresholds, you pay zero federal tax on long-term capital gains. This is extraordinary: you can realize gains and owe nothing to the IRS.

15% Rate (Most Common)​

Single Filers: Taxable income from approximately $47,025 to $518,900 Married Filing Jointly: Taxable income from approximately $94,050 to $583,750

The 15% rate applies to most middle-class and upper-middle-class investors. Even high earners—six-figure salaries, successful professionals—often fall into this bracket for long-term gains.

20% Rate (Top Earners)​

Single Filers: Taxable income above approximately $518,900 Married Filing Jointly: Taxable income above approximately $583,750

Only the highest earners pay 20% on long-term gains. This applies to millionaires, large business owners, and those in the 37% ordinary income bracket.

The Power of Preferential Rates: A Concrete Example​

Comparing short-term and long-term tax outcomes​

To illustrate the impact, let's compare the tax on the same $100,000 realized gain under short-term and long-term scenarios:

Scenario 1: Short-Term Gain (Held 8 months)

Investor is married filing jointly with $350,000 taxable income (from employment). She realizes a $100,000 short-term gain.

  • New taxable income: $450,000
  • This income falls into the 32% ordinary income bracket (married, $383,900–$487,450)
  • Federal tax on the gain: $32,000 (32% of $100,000)
  • State tax (assume 5%): $5,000
  • NIIT (3.8%, if triggered): $3,800
  • Total tax: ~$40,800
  • Net profit: $59,200
  • Effective tax rate: 40.8%

Scenario 2: Long-Term Gain (Held 14 months)

Same investor, same $100,000 gain, but held long-term.

  • The gain is now taxed at the long-term capital gains rate, not ordinary income rates
  • Income of $350,000 (employment) + $100,000 (long-term gain) = $450,000
  • The first portion of the gain (up to $583,750 threshold) is taxed at 15%
  • Federal tax on the gain: $15,000 (15% of $100,000)
  • State tax (may differ for long-term; assume 3%): $3,000
  • NIIT (3.8%): $3,800
  • Total tax: ~$21,800
  • Net profit: $78,200
  • Effective tax rate: 21.8%

The difference: waiting 6 months (from 8 to 14 months) saves $19,000 in taxes on the same $100,000 gain. That's a 46% reduction in tax.

Over 20 years of investing, this difference compounds to hundreds of thousands of dollars.

The Zero Percent Rate: A Hidden Treasure​

The 0% bracket is often overlooked, yet it represents one of the most powerful tax-planning opportunities for lower and middle-income investors.

If your taxable income (including long-term gains) is below ~$47,000 (single) or ~$94,000 (married), your long-term capital gains are taxed at 0%. You can realize $10,000, $50,000, or even $100,000 of long-term gains and owe zero federal capital gains tax.

Who benefits?

  • Retirees with modest pensions and Social Security income, supplemented by portfolio withdrawals
  • Lower-income workers taking a year off or working part-time
  • Spouses in a couple where one partner has minimal income
  • Anyone in a year with unusually low income

Example: Retiree Tax Planning

Sarah retires at 62 with a $25,000 annual pension and $20,000 in Social Security (total $45,000 income). She has a portfolio with $500,000 in unrealized gains.

Normally, she might hesitate to sell appreciated securities (generating short-term or long-term gains) because she thought any gain would be taxed. But if she realizes $45,000 of long-term capital gains, her total taxable income is $90,000—well within the 0% bracket for married filers. She owes zero federal tax on those gains.

In years where she needs cash and her income is low, she can harvest gains tax-free. Over 20 years of retirement, she might realize $900,000 in long-term gains completely tax-free. This strategy, called "harvesting the 0% bracket" or "gain harvesting," is a cornerstone of tax-efficient retirement.

Long-Term vs. Short-Term: The Bracket Difference​

A key distinction: long-term and short-term gains have separate bracket structures.

Short-term gains are added to your ordinary income and taxed at your marginal rate (10–37%). If you earn $300,000 and realize a $50,000 short-term gain, your $350,000 total income is taxed in the 32% bracket. The gain is taxed at 32%.

Long-term gains have their own brackets. The same investor with a $50,000 long-term gain is taxed at 15% on the portion up to the 15% bracket cap, then 20% on the portion above. The gain does not push the investor into the 32% bracket for ordinary income purposes.

This structural difference is enormous. Long-term gains don't cause "bracket creep" the way short-term gains do.

Net Investment Income Tax (NIIT): An Additional 3.8%​

For higher-income investors, there's one additional tax on top of capital gains rates: the Net Investment Income Tax (NIIT), also called the Medicare surcharge.

If your modified adjusted gross income (MAGI) exceeds:

  • $200,000 (single)
  • $250,000 (married filing jointly)
  • $125,000 (married filing separately)

You owe an additional 3.8% tax on the lesser of:

  1. Your net investment income (including long-term capital gains), or
  2. The amount your MAGI exceeds the threshold

Example: A married couple with $350,000 MAGI and $100,000 of long-term capital gains has MAGI exceeding the $250,000 threshold by $100,000. They owe 3.8% NIIT on the lesser of the $100,000 gain or the $100,000 excess MAGI. Tax: $3,800.

This brings the true marginal rate on long-term gains for high earners to 23.8% (20% + 3.8%), still favorable compared to ordinary income rates.

State Taxes on Long-Term Gains​

Federal rates are only part of the story. States also tax capital gains.

Some states offer no preferential treatment for capital gains—they tax them as ordinary income. Others offer reduced rates. A few (like Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, Wyoming) have no income tax at all.

High-tax states and long-term gains:

  • California: Taxes long-term gains as ordinary income (no preferential rate), with top state rate of 13.3%
  • New York: Similar, top state rate of 10.9%
  • New Jersey: Top state rate of 10.75%

A high-income investor in California selling a long-term gain faces federal tax (20%) + state tax (13.3%) + NIIT (3.8%) = 37.1% total tax. This is still lower than the short-term federal rate (37%) plus state tax (13.3%) = 50.3%, but the advantage is reduced.

Conversely, states like Florida and Texas have zero capital gains tax, making them attractive to large investors. However, state residency and domicile rules are complex; don't change residence solely for tax purposes without consulting a tax attorney.

Long-Term Gains and Roth Conversions​

Long-term capital gains interact with Roth conversions, a powerful retirement-planning tool. When you convert a traditional IRA to a Roth, you pay tax on the converted amount at ordinary income rates. But you might strategically time a Roth conversion in a year when you realize long-term capital gains, because the gains will be taxed at preferential rates regardless of your ordinary income bracket.

Example: You have a year with $200,000 of long-term capital gains and no employment income. Your taxable income is $200,000 entirely from gains, taxed at 15%. If you convert $100,000 of traditional IRA to Roth, the conversion amount ($100,000) is taxed as ordinary income starting at your marginal rate. But the long-term gains are still taxed at 15%, not pushed to 37%. You've effectively separated the tax brackets.

This is advanced planning and requires careful execution, but it illustrates how preferential long-term rates enable sophisticated tax strategies.

Historical Context: Why These Rates Exist​

Congress has historically set capital gains rates lower than ordinary income rates to encourage investment and wealth building. The current rate structure dates to the Tax Cuts and Jobs Act of 2017. Before that, rates were different; before 2003, long-term rates were 10%, 15%, or 20% (similar), and even earlier they were 28%.

These rates are not permanent. Congress changes capital gains rates when it passes tax legislation. The current rates are set to expire (revert to pre-2017 levels) in 2026, unless Congress extends them. This is one reason to be aware of pending tax changes—your planning may shift if rates change.

Common Mistakes​

Selling too early to lock in gains. Some investors realize they have a gain and sell immediately, without considering whether the one-year threshold is near. Selling 10 months into the holding period costs thousands in tax compared to waiting two months.

Not understanding state taxes. Investors move to a low-tax state after realizing gains, but state taxes are determined by residency at the time of sale. Moving after the sale doesn't help; you owed the tax when the gain was realized.

Realizing unnecessary gains in high-income years. A business owner might have a big year (six-figure income) and be tempted to sell appreciated securities. Better to defer the sale to a lower-income year if possible, or use losses to offset.

Forgetting about NIIT. Investors calculate long-term gains tax as 15% or 20% and forget about the 3.8% NIIT, which can push the effective rate to 23.8%. Not huge, but significant on large gains.

Holding on to losers to avoid gains. Some investors hold losing positions because they're afraid of realizing gains elsewhere. This is backwards thinking. If you have a losing position and a winning position, sell the loser (harvest the loss) and hold or reduce the winner. Use the loss to offset the gain and reduce net tax.

FAQ​

If I'm in a high income bracket, are ALL my long-term gains taxed at 20%? No. You pay 0% up to the 0% bracket threshold, then 15% from there up to the 15% bracket threshold, then 20% on anything above. You don't jump straight to 20%. This is why even high earners benefit from long-term rates.

Does getting married change my long-term capital gains tax? Yes, if you file married filing jointly, you get much higher bracket thresholds. A couple with $500,000 of long-term gains would pay 15% on most of it (up to $583,750 threshold for married filing jointly), whereas two singles in the same situation would pay 20% on the excess above $518,900. Marriage can be tax-efficient for investors.

Are long-term gains counted as income for Medicare premiums? Yes. Long-term capital gains are part of your MAGI, which determines if you owe higher Medicare surcharges. This is an often-overlooked tax consequence, particularly for retirees.

What if I inherit stock with unrealized gains? Do I owe tax? No. Your cost basis is stepped up to the fair market value at the decedent's death. Any gain that occurred during the decedent's lifetime is forgiven and never taxed. This is one reason holding appreciated assets until death is often optimal.

Can I gift appreciated stock to a family member to avoid the tax? No. When you gift stock, the recipient inherits your cost basis. If they later sell at a gain, they pay tax on the same gain. Gifting does not eliminate the tax; it transfers it. However, charities are different: donations to qualified charities avoid capital gains tax.

Are capital gains from selling a home taxed as long-term gains? Partially. Home sale gains have a special exclusion: $250,000 (single) or $500,000 (married filing jointly) of gain is tax-free if you meet the residence test (owned and lived in 2 of the last 5 years). Gain above the exclusion is taxed as long-term capital gain.

Summary​

Long-term capital gains are taxed at just 0%, 15%, or 20% federally, making them the most favorable form of income available to individual investors. This preferential treatment rewards patience and buy-and-hold investing. By simply holding an appreciated investment for over one year, investors can reduce tax rates by 10–37 percentage points compared to short-term rates. The 0% bracket is particularly powerful for lower-income investors and retirees. Understanding long-term capital gains rates is essential for maximizing after-tax returns over a lifetime of investing. Tax rules and rates change periodically, so confirm current figures with the IRS or a qualified tax professional.
