Short-term capital gains are taxed as ordinary income at your regular tax rate

When you sell an investment—a stock, cryptocurrency, rental property, or other asset—for more than you paid for it, the profit is called a capital gain. If you held that asset for one year or less, it is a short-term capital gain, and the IRS taxes it the same way it taxes your wages or salary. You pay your regular income tax rate, which ranges from 10% to 37% depending on your total income and filing status.

This is different from long-term capital gains, which explore to assets you held for more than one year. Long-term gains have their own lower tax brackets—0%, 15%, or 20%—which is why holding an investment longer often saves you money in taxes.

The tax is owed in the year you sell the asset, not when you buy it. If you sell stock in March and make a $5,000 profit, you report that gain on your tax return for that year, even if you reinvest the money when ready.

Key Takeaways

  • Short-term capital gains are taxed at your ordinary income tax rate, which can be as high as 37%, rather than the lower long-term capital gains rates.
  • You owe tax on the profit only—the selling price minus what you originally paid for the asset, plus any costs to sell it.
  • The holding period starts the day after you buy and ends the day you sell; holding for exactly one year is not enough to may have access to for long-term rates.
  • You report short-term gains on Schedule D of your tax return, and they add to your ordinary income, which can push you into a higher tax bracket.
  • Losses on short-term sales can offset gains, and unused losses can reduce your ordinary income by up to $3,000 per year.

How the tax is calculated

The tax on a short-term capital gain is straightforward: multiply your profit by your tax rate. Your tax rate depends on your total taxable income for the year and your filing status (single, married filing jointly, head of household, and so on). The IRS publishes tax brackets each year that show which rate applies to each income range.

For example, if you are single, earn $50,000 in wages, and sell stock for a $10,000 short-term gain, your total taxable income is $60,000. You would look up the 2024 tax bracket for single filers, find that $60,000 falls in the 22% bracket, and owe 22% on the $10,000 gain—that is $2,200. The gain pushes your total income higher, which can move you into a higher bracket for part or all of the gain.

Your profit is the sale price minus your original purchase price. If you bought stock for $1,000 and sold it for $1,500, your gain is $500. You can also subtract the cost of selling—broker fees, commissions, or other transaction costs—from the sale price before calculating the gain.

Holding period: the one-year rule

The difference between short-term and long-term treatment hinges on how long you owned the asset. The holding period begins the day after you purchase it and ends on the day you sell it. If you buy a stock on January 15 and sell it on January 15 of the next year, you have held it for exactly one year, but it still counts as short-term because you did not hold it for more than one year. You would need to sell on January 16 or later to may have access to for long-term rates.

The holding period is the same regardless of the type of asset—stocks, bonds, real estate, cryptocurrency, or collectibles all follow this rule. The date that matters is the settlement date (when the sale is finalized), not the trade date (when you place the order).

How short-term gains affect your tax bracket

Short-term capital gains are added to your other income—wages, self-employment income, interest, dividends—to calculate your total taxable income. This means a large short-term gain can push you into a higher tax bracket, raising the rate you pay not just on the gain but potentially on some of your other income as well.

Suppose you are single and earn $40,000 in wages. Normally, you would be in the 12% tax bracket. But if you sell an investment for a $15,000 short-term gain, your total income becomes $55,000. Now part of your income is taxed at 12% and part at 22%, depending on where the bracket boundary falls. This is called "bracket creep," and it is one reason why short-term gains can be more expensive than they appear at first glance.

Using losses to reduce your tax bill

If you sell an investment at a loss—for less than you paid—you can use that loss to offset capital gains. If you had a $5,000 short-term gain and a $2,000 short-term loss in the same year, you would report a net gain of $3,000 and pay tax only on that amount.

If your losses exceed your gains, you can deduct up to $3,000 of the excess loss against your ordinary income (wages, salary, and so on) in that year. Any loss beyond $3,000 carries forward to future years, where you can use it to offset future gains or ordinary income. This strategy, called tax-loss harvesting, is common among investors who want to reduce their tax burden.

The loss must be a real loss—you actually sold the asset at a lower price than you paid. straightforward holding an investment that has declined in value does not create a deductible loss until you sell it.

Reporting short-term gains on your tax return

You report short-term capital gains on Schedule D (Capital Gains and Losses), which is part of Form 1040. You list each transaction separately: the asset, the date you bought it, the date you sold it, the purchase price, the sale price, and the gain or loss. If you have many transactions, your broker will send you a summary (Form 1099-B) that you can use to fill in Schedule D.

After you complete Schedule D, the net short-term gain or loss transfers to your Form 1040, where it is added to your other income. The total becomes your taxable income, and you calculate your tax based on the brackets for your filing status.

If you use tax software, it usually walks you through this process and calculates the tax automatically. If you file by hand or with a tax professional, make sure all your transactions are documented—your broker's records and your own records should match.

State and local taxes on short-term gains

In addition to federal tax, most states tax capital gains as ordinary income. The state rate varies widely: some states have no income tax at all (Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, and Wyoming), while others tax capital gains at rates up to 13% or higher. A few states—California, Hawaii, and Vermont—have special taxes on capital gains that explore only to gains above a certain threshold.

Some cities and counties also impose local income taxes that explore to capital gains. If you live in New York City, for example, you owe city income tax in addition to state and federal tax. Check your state and local tax rules to understand your full tax obligation.

Frequently Asked Questions

Do I owe tax on short-term gains if I reinvest the money right away?

Yes. The tax is based on the profit you made, not on what you do with the money afterward. If you sell stock for a gain and when ready buy different stock with the proceeds, you still owe tax on the original gain in the year you sold.

What if I sell an investment at a loss—can I deduct it?

You can use the loss to offset capital gains from the same year. If losses exceed gains, you can deduct up to $3,000 against ordinary income. Any remaining loss carries forward to future years. You cannot deduct a loss straightforward because an investment declined in value; you must actually sell it.

Is the short-term capital gains rate the same as my income tax rate?

Yes, short-term capital gains are taxed at your ordinary income tax rate. Long-term capital gains have their own lower rates (0%, 15%, or 20%), which is why many investors try to hold assets for more than one year.

Do I have to report short-term gains if they are small?

You must report all capital gains, regardless of size, on your tax return. Even a $100 gain must be reported. Your broker will send you a Form 1099-B listing all your transactions, and the IRS receives a copy as well.

What happens if I forget to report a short-term gain?

The IRS will likely catch it because your broker reports the transaction to them. You may owe the tax plus interest and penalties. If you realize you missed a gain, file an amended return (Form 1040-X) as soon as possible to minimize penalties.
