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

When you sell an investment you have owned for one year or less, the profit counts as short-term capital gain. The IRS taxes this profit at the same rate as your wages, salary, or other ordinary income. That rate depends on your tax bracket for the year — it could be 10%, 12%, 22%, 24%, 32%, 35%, or 37%, depending on how much total income you earned.

This is different from long-term capital gains, which get preferential tax rates (0%, 15%, or 20% for most people). The timing of when you sell matters entirely. If you bought a stock on March 15 and sold it on March 14 the following year, it is long-term. If you sold it on March 15 of the same year, it is short-term and taxed much higher.

You report short-term capital gains on Schedule D of your tax return, and they add directly to your other income for the year. This can push you into a higher tax bracket, meaning you may pay more tax on your short-term gains than you would on the same dollar amount of long-term gains.

Key Takeaways

  • Short-term capital gains are taxed at your ordinary income tax rate, which ranges from 10% to 37% depending on your total income for the year.
  • The holding period is measured from the purchase date to the sale date; you must own an investment for more than one year for it to may have access to as long-term.
  • Short-term gains are added to all your other income on your tax return, which can push you into a higher tax bracket and increase your overall tax bill.
  • You report short-term capital gains on Schedule D (Form 1040) when you file your federal income tax return.
  • Losses from short-term sales can offset short-term gains dollar-for-dollar, and excess losses can reduce other income up to $3,000 per year.

How the holding period is calculated

The IRS counts the holding period from the day after you buy an investment to the day you sell it. If you bought shares on January 15, the holding period starts on January 16. If you sell on January 16 of the next year, you have held it for exactly one year, and it qualifies as long-term. If you sell on January 15 of the next year, it is short-term.

This rule applies to stocks, bonds, mutual funds, real estate, and most other assets. The date matters precisely — there is no grace period. Many investors set calendar reminders one year after a purchase to remind themselves when they can sell without short-term tax consequences.

If you inherit an investment, the holding period does not carry over from the previous owner. Your holding period begins on the date of death of the person who left it to you, which usually means inherited investments are treated as long-term regardless of how long the previous owner held them.

Your tax bracket determines your short-term rate

Short-term capital gains do not have their own tax rate. Instead, they are taxed at whatever rate applies to your ordinary income. The 2024 tax brackets for single filers range from 10% on income up to $11,600 to 37% on income over $578,100. For married couples filing jointly, the brackets are wider but the rates are the same.

Your tax bracket is determined by your total income for the year: wages, salary, self-employment income, interest, dividends, and short-term capital gains all stack together. If you earned $60,000 in salary and have a $10,000 short-term gain, you are taxed as if you earned $70,000 total. That $10,000 gain may be taxed at 22% or 24%, depending on where it falls in the bracket.

This stacking effect is why short-term gains can be expensive. A $10,000 short-term gain might cost you $2,200 in federal tax (at 22%) or $3,700 (at 37%), whereas the same $10,000 in long-term gains might cost only $1,500 (at 15%) or nothing (at 0% if you are in a low-income bracket).

How short-term gains appear on your tax return

You report all short-term capital gains and losses on Schedule D, which is part of Form 1040. List each transaction separately: the asset name, the date acquired, the date sold, the sales price, the cost basis (what you paid for it), and the gain or loss. If you have many transactions, you may need to attach a separate statement listing them all.

The Schedule D totals your short-term gains and losses separately from your long-term gains and losses. If your short-term gains exceed your short-term losses, the net amount goes to line 15 of Schedule D and then to your Form 1040. This amount is added to your ordinary income and taxed at your regular rate.

If you use tax software, it usually walks you through entering each transaction and calculates the gain or loss automatically. If you use a tax preparer, provide them with a brokerage statement or a list of all sales from the year, including the purchase date, sale date, and price for each.

Using losses to reduce your tax bill

If you sell an investment at a loss, you can use that loss to offset gains. A $5,000 short-term loss cancels out a $5,000 short-term gain, leaving you with no tax on that transaction. You can also use short-term losses to offset long-term gains, though the reverse is also true — long-term losses can offset short-term gains.

If your losses exceed your gains in a year, you can deduct up to $3,000 of the excess loss against your other income (wages, salary, interest, and so on). Any loss beyond $3,000 carries forward to future years, where you can use it again. This carryforward has no expiration date — you can use it whenever you have gains or income to offset.

Many investors use this strategy deliberately, selling losing positions late in the year to offset gains from winning positions. This is called tax-loss harvesting. However, if you sell a security at a loss and buy the same or a substantially identical security within 30 days before or after the sale, the loss is disallowed under the wash-sale rule. The loss is added to the cost basis of the new purchase instead.

State and local taxes on short-term gains

In addition to federal tax, most states tax short-term 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, Wyoming), while others tax capital gains at rates up to 13% or higher. A few states, including California and New York, tax short-term gains at the same rate as long-term gains, meaning there is no state-level advantage to holding longer.

Some cities and counties also impose local income taxes that explore to capital gains. New York City, for example, taxes residents on short-term gains at rates up to 3.876% in addition to state and federal tax. If you live in a high-tax state or city, the total tax on a short-term gain can exceed 50% of the profit.

If you are considering moving to reduce taxes, remember that you must establish residency in the new location before you sell. straightforward moving after the sale does not change which state taxes the gain — the state where you lived when you sold is the one that taxes it.

Common mistakes to avoid

The most common mistake is forgetting to track the purchase date. If you cannot prove when you bought an investment, the IRS assumes you held it for the shortest possible time, which means short-term treatment and higher tax. Keep brokerage statements, confirmation emails, or a personal record of every purchase.

Another mistake is assuming that reinvested dividends or distributions reset the holding period. They do not. If you bought a mutual fund on January 1 and it paid a dividend that you reinvested on June 1, your holding period for the original shares still started on January 1. The reinvested dividend is a separate purchase with its own holding period starting June 2.

A third mistake is selling at a loss and when ready buying back the same investment to "reset" the clock. The wash-sale rule prevents this. You must wait 30 days after selling at a loss before buying the same security again, or the loss is disallowed. The 30-day window runs from 30 days before the sale through 30 days after.

Frequently Asked Questions

Can I avoid short-term capital gains tax by holding an investment for 366 days instead of 365?

No. The IRS counts the holding period from the day after purchase to the day of sale. If you bought on January 15 and sell on January 16 of the next year, you have held it for one year and one day, which qualifies as long-term. But if you sell on January 15, it is short-term. The exact calendar date matters, not the number of days.

What happens to short-term capital gains if I die before filing my tax return?

Your estate or heirs must report the gains on your final tax return for the year of death. The gains are taxed at your ordinary rate for that year. However, inherited investments receive a "step-up in basis," meaning the cost basis is adjusted to the fair market value on the date of death, which can eliminate or reduce future capital gains tax for the heirs.

Do I have to pay estimated taxes on short-term capital gains during the year?

If you expect to owe more than $1,000 in federal income tax for the year (including tax on short-term gains), you may need to make quarterly estimated tax payments. Use Form 1040-ES to calculate what you owe and when to pay. Missing estimated payments can result in penalties, even if you pay the full amount when you file your return.

Are short-term capital gains subject to the net investment income tax?

Yes. If your modified adjusted gross income exceeds $200,000 (single) or $250,000 (married filing jointly), you owe an additional 3.8% net investment income tax on short-term capital gains, along with long-term gains, dividends, and interest. This tax is reported on Form 8960 and added to your Form 1040.

Can I deduct investment losses from my short-term gains if I have not sold yet?

No. You can only use realized losses — from sales you have actually completed — to offset gains. Unrealized losses (on investments you still own) cannot be deducted. You must sell the losing investment to use the loss on your tax return.
