What Is the Minimum Income for Capital Gains Tax?

The minimum income for capital gains tax depends entirely on how long you held the asset. For long-term gains in the 2026 tax year, you owe no federal capital gains tax as long as your total taxable income stays at or below $49,450 if you file single, $98,900 if you’re married filing jointly, or $66,200 as head of household.¹ Short-term gains have no such floor: profit on anything you held for a year or less is taxed as ordinary income starting with the first dollar.²

Why the Minimum Only Exists for Long-Term Gains

Federal law splits capital gains into two categories based on how long you owned the asset. Sell within one year of purchase and the profit is a short-term gain, taxed at your ordinary income rate, which runs up to 37 percent.² Hold for more than one year and the profit qualifies as a long-term gain, eligible for the preferential rates of 0, 15, or 20 percent.³

Only the long-term rate schedule contains a zero bracket. That’s the “minimum income” everyone asks about: below it, long-term gains are federally tax-free. Short-term gains follow the regular income tax brackets and get taxed the same way your wages do, so there is no comparable exemption for them.

The 2026 Zero-Percent Income Ceilings

For the 2026 tax year, the taxable income ceilings for the zero-percent long-term capital gains rate are:¹

Single filers: up to $49,450
Married filing jointly: up to $98,900
Head of household: up to $66,200

These figures are taxable income, not gross income, and the distinction changes the math significantly. Taxable income is what remains after you subtract the standard deduction and any other adjustments. For 2026, the standard deduction is $16,100 for single filers and $32,200 for married couples filing jointly.¹ A married couple earning $120,000 in gross income and taking the standard deduction has a taxable income of roughly $87,800, which sits inside the zero-percent bracket. That couple could sell long-held stock at a gain and owe no federal capital gains tax, provided the gain doesn’t push their taxable income above $98,900.

How Gains Stack on Top of Other Income

Capital gains don’t sit in their own private bucket. They stack on top of your other taxable income, which means a large gain can push you out of the zero bracket even if your wages alone would have kept you inside it.

Here’s how the split works. Say your taxable income before the sale is $90,000 and you’re married filing jointly. You sell a stock you’ve owned for three years and realize a $20,000 long-term gain. The first $8,900 of that gain fits within the remaining space in the zero-percent bracket ($98,900 minus $90,000), so it’s tax-free. The remaining $11,100 spills into the 15-percent bracket and gets taxed at that rate.² The IRS doesn’t retroactively tax the entire gain at 15 percent; it splits the gain across the brackets you cross.

This is why the “minimum income for capital gains tax” isn’t a simple income figure but a ceiling on the sum of your other income plus the gain itself. To realize a gain entirely at zero percent, your taxable income including the gain has to stay below the threshold.

What Applies Above the Zero Bracket

Once taxable income crosses the zero-percent ceiling, long-term gains are taxed at 15 percent. For 2026 the 15-percent rate covers taxable income between the following:

Single filers: $49,451 to $545,500
Married filing jointly: $98,901 to $613,700
Head of household: $66,201 to $579,600

The 20-percent rate applies only to taxable income above those upper thresholds.² Even then, only the portion above the 15-percent ceiling is taxed at 20 percent; the rest of the gain stays at the lower rates.

Two boundaries worth noting. Long-term gains on collectibles like art, coins, and precious metals are taxed at up to 28 percent, regardless of income.² And cryptocurrency, NFTs, and other digital assets are treated as property, so the same capital gains rules apply to every sale or exchange.⁴

A Separate Income Threshold: The 3.8 Percent Surtax

Higher earners face an additional layer that’s easy to miss. The net investment income tax adds 3.8 percent on top of your capital gains rate when your modified adjusted gross income exceeds $200,000 for single filers or $250,000 for married couples filing jointly.⁵ These thresholds are not indexed for inflation, so more taxpayers cross them each year as incomes rise.⁶

The surtax applies to the lesser of your net investment income or the amount by which your modified adjusted gross income exceeds the threshold. Capital gains, dividends, interest, rental income, and royalties all count as investment income.⁷ A single filer with $220,000 in modified adjusted gross income and $50,000 in long-term gains would owe the 3.8-percent surtax on $20,000 (the amount over $200,000), not the full $50,000. The combined federal rate on long-term gains for the highest earners tops out at 23.8 percent.

The Home Sale Exclusion Is a Different Threshold

If your capital gain comes from selling your main home, a separate rule may wipe out the tax entirely regardless of your income. You can exclude up to $250,000 of profit if you’re single, or up to $500,000 if you’re married filing jointly. To qualify, you must have owned and used the home as your primary residence for at least two of the five years before the sale, and those two years don’t have to be consecutive.⁸ Only profit above the exclusion is subject to capital gains tax.

A partial exclusion is available if you have to sell before hitting the two-year mark because of a job relocation, health issue, or unforeseeable event.⁹ The partial amount is a fraction of the full $250,000 or $500,000 based on how much of the two-year requirement you completed.

You Still Have to Report the Gain

Falling below the zero-percent income threshold means you owe no tax on the gain. It doesn’t mean you can skip reporting it. There is no minimum dollar amount that exempts a capital gain from your federal tax return. Brokerage firms report sales to the IRS on Form 1099-B, and the IRS matches that data to your filing.¹⁰

You report gains and losses on Schedule D and, in most cases, Form 8949, which lists each transaction. When the 1099-B shows the correct cost basis and no adjustments are needed, you may be able to report the totals directly on Schedule D without Form 8949.¹¹ The accuracy-related penalty for underreporting is 20 percent of the underpayment.¹²

State Taxes May Still Apply

Even if your income sits below the federal zero-percent ceiling, your state may still tax the gain. Most states treat capital gains as ordinary income. Rates range from zero in states with no income tax to over 13 percent in the highest-tax states, and a handful of states exempt some or all long-term gains. The combined federal and state rate on a long-term gain can land anywhere from zero to well over 30 percent depending on where you live and what you earn.
