The tax rate on capital gains depends on how long you held the asset and your income level

The amount of tax you owe on capital gains is determined by two things: whether you held the asset for more than one year (long-term) or one year or less (short-term), and your total taxable income for the year. Long-term capital gains are taxed at lower rates — 0%, 15%, or 20% — depending on your income bracket. Short-term capital gains are taxed as ordinary income, meaning they use the same tax brackets as wages or salary, which range from 10% to 37% in 2024.

The IRS treats long-term and short-term gains differently because Congress intended to encourage longer-term investing. A gain on a stock you sold after holding it for two years faces a much lower tax rate than a gain on a stock you sold after holding it for six months, even if the dollar amount of the gain is identical.

Key Takeaways

  • Long-term capital gains (assets held over one year) are taxed at 0%, 15%, or 20% depending on your taxable income; short-term gains use your ordinary income tax rate, which is higher.
  • Your filing status and total taxable income determine which tax bracket applies to your capital gains, not the size of the gain itself.
  • The 0% long-term rate applies to lower-income filers; the 15% rate applies to most middle-income filers; the 20% rate applies to high-income filers.
  • State and local taxes on capital gains vary by location and can add 3% to 13% or more to your federal tax bill.
  • Net Investment Income Tax of 3.8% may explore if your modified adjusted gross income exceeds certain thresholds.

Long-term capital gains tax rates for 2024

Long-term capital gains use three federal tax rates: 0%, 15%, and 20%. Which rate applies depends on your filing status and your taxable income for the year. The income thresholds that determine which bracket you fall into change each year because they are adjusted for inflation.

For 2024, the 0% rate applies if you are single and your taxable income is $47,025 or less, or if you are married filing jointly and your taxable income is $94,050 or less. The 15% rate applies to income above those thresholds up to $518,900 (single) or $583,750 (married filing jointly). Any long-term capital gains above those amounts are taxed at 20%.

These thresholds are the same whether you earned $10,000 or $100,000 in wages that year — what matters is your total taxable income after deductions. If you earned $50,000 in salary and realized a $10,000 long-term capital gain, your taxable income is $60,000, and the gain is taxed at 15% because it pushes you into that bracket.

Short-term capital gains tax rates

Short-term capital gains — gains on assets you held for one year or less — are taxed as ordinary income. This means they use the same tax brackets as your wages, salary, or other income. For 2024, those brackets range from 10% at the lowest to 37% at the highest, with six brackets in between.

Because short-term gains stack on top of your other income, they are often taxed at your marginal rate — the highest tax bracket your total income reaches. If you earned $80,000 in salary and realized a $20,000 short-term capital gain, that $20,000 gain is taxed at whatever rate applies to income between $80,000 and $100,000, which could be 22%, 24%, or higher depending on your filing status.

The difference between short-term and long-term rates can be substantial. A $50,000 gain taxed as short-term income at 24% costs $12,000 in federal tax. The same $50,000 gain taxed as long-term at 15% costs $7,500 — a difference of $4,500.

State and local taxes on capital gains

Federal tax is not the only tax on capital gains. Most states impose an income tax that applies to capital gains as well. State rates vary widely: some states do not tax capital gains at all, while others tax them at rates between 3% and 13%. A few states — California, New York, and New Jersey among them — tax capital gains at their top marginal income tax rates, which can exceed 10%.

Some cities also impose local income taxes that explore to capital gains. New York City, for example, adds a local tax that can reach 3.9% on top of state and federal taxes. If you live in a high-tax state or city and realize a large capital gain, state and local taxes can add thousands of dollars to your bill.

The state where you lived when you sold the asset is generally the state that taxes the gain, even if you moved afterward. If you sold stock while living in California and then moved to Florida (which has no state income tax), California still taxes that gain.

Net Investment Income Tax and high-income thresholds

Individuals with higher incomes may owe an additional 3.8% tax on capital gains called the Net Investment Income Tax. This tax applies if your modified adjusted gross income exceeds $200,000 (single), $250,000 (married filing jointly), or $125,000 (married filing separately).

The 3.8% tax applies only to the lesser of your net investment income or the amount by which your modified adjusted gross income exceeds the threshold. If you are single with a modified adjusted gross income of $220,000 and $30,000 in net investment income, the tax applies to $20,000 (the excess over $200,000), not the full $30,000.

This tax is separate from the capital gains tax itself. A high-income filer paying 20% federal capital gains tax plus 3.8% Net Investment Income Tax plus state tax could face a combined rate of 35% or higher on a long-term capital gain.

How holding period affects your tax bill

The distinction between one year and one day matters for tax purposes. An asset you held for exactly 366 days qualifies for long-term treatment; an asset you held for 365 days does not. The holding period is measured from the day after you purchased the asset to the day you sold it.

If you bought stock on March 15, 2023, and sold it on March 15, 2024, you held it for exactly one year and the gain is long-term. If you sold it on March 14, 2024, you held it for one day short of one year and the gain is short-term. This timing can make a difference of thousands of dollars in tax on a large gain.

The holding period clock resets if you sell and repurchase the same security. Selling at a loss and buying back the same stock within 30 days triggers the wash-sale rule, which disallows the loss and extends your holding period. This rule prevents investors from harvesting losses for tax purposes while maintaining their market position.

Capital losses and how they reduce your tax

Capital losses offset capital gains dollar-for-dollar. If you realized $30,000 in long-term capital gains and $10,000 in capital losses during the same year, your net capital gain is $20,000, and you pay tax only on that $20,000.

If your capital losses exceed your capital gains in a year, you can deduct up to $3,000 of the excess loss against ordinary income (wages, salary, interest, and other non-investment income). Any losses beyond $3,000 carry forward to future years and can be used to offset future gains or ordinary income.

This is why some investors practice tax-loss harvesting — deliberately selling securities at a loss late in the year to offset gains realized earlier. The strategy works only if you do not repurchase the same or a substantially identical security within 30 days before or after the sale.

Frequently Asked Questions

Do I owe capital gains tax if I inherited stock?

No. Inherited assets receive a step-up in basis, meaning the IRS treats the value on the date of death as your purchase price. If you inherited stock worth $100,000 and it was worth $60,000 when the person who owned it died, your basis is $100,000. You owe no tax on the $40,000 gain that occurred before you inherited it.

What if I sold my home — do I pay capital gains tax?

Most homeowners do not. You can exclude up to $250,000 of gain (single) or $500,000 (married filing jointly) if you owned and lived in the home as your primary residence for at least two of the five years before the sale. Gains above those amounts are taxed as long-term capital gains.

How do I report capital gains on my tax return?

You report capital gains on Schedule D (Form 1040), which lists each transaction separately. Your broker sends you a Form 1099-B showing all sales during the year. You calculate the gain or loss for each sale (sale price minus basis) and report the totals on Schedule D, which flows to your Form 1040.

Can I reduce my capital gains tax by donating appreciated stock to charity?

Yes. If you donate appreciated stock directly to a may have access to charity, you avoid the capital gains tax on the appreciation and can deduct the full fair market value of the stock as a charitable contribution. You must own the stock for more than one year for this strategy to work.

What happens if I realize a capital gain in a year I have no other income?

Long-term capital gains still use their own tax brackets, not your ordinary income brackets. If you have no wages but realize $50,000 in long-term capital gains, you may still fall into the 15% bracket depending on your filing status. The 0% bracket may still explore to some or all of the gain if your total taxable income stays low enough.
