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

When you sell an investment you've held for one year or less, the profit is a short-term capital gain, and it's taxed the same way as wages or salary. There is no separate short-term capital gains tax rate — instead, you pay your ordinary income tax rate, which ranges from 10% to 37% depending on your total income for the year.

This is different from long-term capital gains, which get preferential rates of 0%, 15%, or 20%. The distinction matters because holding an investment just a few months longer can cut your tax bill significantly. The IRS counts the holding period from the day after you buy to the day you sell, and the one-year mark is the dividing line.

Your actual short-term rate depends on which tax bracket you fall into for that year. If you're in the 22% bracket, short-term gains are taxed at 22%. If you're in the 35% bracket, they're taxed at 35%. Your total income for the year — wages, interest, short-term gains, and other sources combined — determines your bracket.

Key Takeaways

  • Short-term capital gains use your ordinary income tax rate (10% to 37%), not a special capital gains rate.
  • You owe short-term rates on any investment sold within one year of purchase, regardless of profit size.
  • Your tax bracket for the year determines your rate, so a short-term gain can push you into a higher bracket and increase the tax on all your income.
  • Long-term capital gains (held over one year) are taxed at lower rates: 0%, 15%, or 20%, depending on income.
  • You report short-term gains on Schedule D of your tax return, and they count as ordinary income for purposes of Medicare premiums and other income-based calculations.

How the IRS counts your holding period

The holding period starts the day after you purchase the investment 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, that's exactly one year, and the gain is long-term. If you sell on January 14, it's short-term.

This rule applies to stocks, mutual funds, bonds, real estate, and any other capital asset. The purchase date on your confirmation statement is what matters — not the settlement date, which may be a few days later. If you're unsure whether a sale qualifies as long-term, your brokerage statement will usually label it for you.

Why short-term gains can push you into a higher tax bracket

Tax brackets are cumulative. If you earn $50,000 in wages and realize a $20,000 short-term gain, the IRS treats your total income as $70,000. That $20,000 gain may push you from the 12% bracket into the 22% bracket, meaning you pay 22% on the gain itself and possibly on the last portion of your wages too.

This "bracket creep" is one reason investors try to time sales to spread gains across multiple years or to years when their income is lower. It's also why some people hold investments longer than they otherwise would — the tax savings from long-term rates can outweigh the benefit of selling sooner.

Short-term gains and other income-based calculations

Short-term capital gains count as ordinary income for more than just your tax bracket. They're included in your Modified Adjusted Gross Income (MAGI), which determines whether you're subject to higher Medicare premiums, whether you can deduct IRA contributions, and whether you're may be able to access for certain tax credits.

If you're near the income threshold for any of these programs, a short-term gain could trigger additional costs or reduce a benefit you were counting on. This is another reason to review the timing of a sale before you execute it.

How to report short-term capital gains on your tax return

You report short-term gains on Schedule D (Form 1040), which is the Capital Gains and Losses form. List each sale separately: the date acquired, the date sold, the cost basis, the sale price, and the gain or loss. If you have many transactions, your brokerage will provide a summary that you can use as a starting point.

Short-term gains go in Part I of Schedule D. Long-term gains go in Part II. The totals from both parts flow to your Form 1040, where short-term gains are added to your ordinary income and long-term gains receive their preferential rates.

If you sold through a brokerage, they will send you a Form 1099-B showing your transactions. Keep your own records of cost basis — the amount you paid plus any fees — because the IRS may not have that information, and you need it to calculate the gain correctly.

Strategies to reduce short-term capital gains tax

The simplest approach is to hold investments longer. If you can wait until the one-year mark, you'll may have access to for long-term rates, which are substantially lower for most taxpayers. If you need to sell sooner, consider whether you have losses elsewhere that can offset the gain.

If you sold an investment at a loss, you can use that loss to reduce your short-term gains dollar-for-dollar. If losses exceed gains, you can deduct up to $3,000 of the net loss against ordinary income in that year, and carry forward any remaining loss to future years. This is called tax-loss harvesting, and it's a common way to manage the tax impact of trading activity.

Another option is to space out sales across different tax years if you have a large position. Selling half in December and half in January spreads the gain across two years and may keep you in a lower bracket in each year than if you sold everything at once.

Frequently Asked Questions

Is there a short-term capital gains tax rate that's different from my income tax rate?

No. Short-term capital gains are taxed at your ordinary income tax rate, which is the same rate applied to wages, interest, and other ordinary income. The rate ranges from 10% to 37% depending on your total income for the year. Long-term gains get preferential rates, but short-term gains do not.

What happens if I sell an investment after 11 months?

It's treated as a short-term gain and taxed at your ordinary income rate. The IRS counts from the day after purchase to the day of sale. If you're close to the one-year mark, waiting a few weeks or months can save you significantly in taxes by may have access to for long-term rates instead.

Can I use short-term losses to offset short-term gains?

Yes. Short-term losses reduce short-term gains dollar-for-dollar. If you have more losses than gains, the excess can reduce ordinary income by up to $3,000 per year, with any remaining loss carried forward to future years. This applies regardless of whether the gains and losses are short-term or long-term.

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

Yes. All capital gains, regardless of size, must be reported on Schedule D. Your brokerage will report them to the IRS on Form 1099-B, so the IRS will know about the sale. Failing to report it can trigger an audit notice.

What if my short-term gain pushes me into a higher tax bracket?

The gain is taxed at your new bracket rate, and it may also push the last portion of your ordinary income into the higher bracket as well. This is why the effective tax rate on a short-term gain can sometimes be higher than your normal bracket rate. Planning the timing of a sale can help you avoid this.
