When you sell an investment for more than you paid, the IRS wants a cut. How big that cut is depends almost entirely on how long you held the investment before selling. Get this wrong and you can hand back a third of your profit. Get it right and some investors pay 0%. Here's how capital gains taxes work in 2026 — and how to minimize them legally.

Short-Term vs. Long-Term: The One Rule That Changes Everything

The IRS draws a hard line at 12 months. Hold an investment for one year or less, sell it at a profit, and you pay short-term capital gains tax — taxed at the same rate as ordinary income, meaning up to 37%. Hold it for more than one year and you pay long-term capital gains tax, which maxes out at 20% for most people and is 0% for lower earners.

That gap is enormous. On a $50,000 gain, someone in the 32% income bracket would pay $16,000 in short-term taxes versus potentially $7,500 in long-term taxes. The only difference: waiting a few more months before selling.

2026 Capital Gains Tax Rates

Long-term capital gains rates are tiered by income, just like regular income taxes. Here are the 2026 brackets for single filers and married filing jointly:

Note: These thresholds reflect 2026 inflation adjustments. Short-term gains are taxed at your marginal income tax rate (10%–37%).

The 0% Capital Gains Rate: Bigger Than People Think

The 0% long-term capital gains rate is one of the most underused tax breaks in personal finance. If your total taxable income — including the capital gain — falls under the threshold, you owe nothing on long-term investment profits.

For 2026, a single filer with $48,350 or less in taxable income pays zero on long-term gains. A married couple can have nearly $97,000 in combined taxable income and still owe nothing on qualifying investment profits.

This creates a legitimate strategy called capital gains harvesting — intentionally realizing gains in a year when your income is low (early retirement, sabbatical, business loss year) to permanently step up your cost basis without paying any tax.

What Counts as a Capital Gain?

Capital gains apply to any asset sold at a profit: stocks, bonds, ETFs, mutual funds, real estate, cryptocurrency, collectibles, and more. A few specifics to know:

• Stocks and ETFs: Standard 0/15/20% long-term rates apply
• Mutual funds: You may owe taxes from fund distributions even if you didn't sell — the fund itself may have sold holdings and must pass gains to shareholders
• Real estate: Long-term rates apply, but primary residences get an exclusion ($250k single / $500k married) if you lived there 2 of the last 5 years
• Cryptocurrency: Treated exactly like stocks — short and long-term rules apply
• Collectibles: Max long-term rate is 28%, not 20%

The Net Investment Income Tax (NIIT)

High earners face a surcharge that most calculators miss. The Net Investment Income Tax adds an additional 3.8% on investment income (including capital gains) for taxpayers above $200,000 (single) or $250,000 (married). This means the real top rate on long-term capital gains is 23.8%, not 20%.

5 Legal Strategies to Reduce Your Capital Gains Tax

1. Hold for More Than One Year

The simplest and most powerful move. Before selling any investment, check your holding period. If you're at 11 months, waiting 30 more days can cut your tax rate in half.

2. Use Tax-Advantaged Accounts

Investments inside a 401(k), IRA, Roth IRA, or HSA aren't subject to capital gains tax at all. Growth and gains inside these accounts are either tax-deferred or tax-free. This is why investing through your HSA can be so powerful for long-term wealth building.

3. Tax-Loss Harvesting

Selling losing positions to offset gains elsewhere is called tax-loss harvesting. If you have $20,000 in gains and $8,000 in losses, you only owe taxes on $12,000. Excess losses beyond gains can offset up to $3,000 of ordinary income annually and carry forward indefinitely.

4. Gift Appreciated Stock (Instead of Cash)

If you plan to give money to charity or family, donate appreciated shares instead of cash. The charity pays no capital gains, and you get a deduction for the full market value. You avoid the tax entirely.

5. Time Sales Around Your Income

Capital gains are added to your total income for the year. If you have a low-income year — between jobs, early retirement, business loss — that's the strategic time to realize large long-term gains and potentially hit the 0% bracket.

Capital Gains in Retirement Accounts

It's worth being explicit: gains inside 401(k)s and traditional IRAs are not capital gains — they're converted to ordinary income when withdrawn. You've deferred the tax, not eliminated it. The capital gains advantage is specifically for taxable brokerage accounts.

Roth accounts are the exception. Qualified withdrawals from a Roth IRA or Roth 401(k) are completely tax-free — not ordinary income, not capital gains, nothing. If you expect to hold investments for decades and want to eliminate taxes at withdrawal, the Roth path is worth understanding.
