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

When you sell an investment you've held for one year or less, the profit is a short-term capital gain. The IRS taxes this gain at your ordinary income tax rate — the same rate you pay on wages, salary, or self-employment income. That rate ranges from 10% to 37% depending on your total income and filing status for the year.

This is the key difference from long-term capital gains, which get preferential rates of 0%, 15%, or 20%. Because short-term gains use your ordinary bracket, they can push you into a higher tax bracket entirely, meaning you may owe tax on the gain at a higher rate than you expected.

The holding period clock starts the day after you buy and ends the day you sell. If you buy on January 15 and sell on January 15 of the next year, that's a long-term gain. If you sell on January 14, it's short-term.

Key Takeaways

  • Short-term capital gains are taxed at your ordinary income tax rate, which ranges from 10% to 37% depending on your income and filing status.
  • A gain is short-term only if you held the investment for one year or less; the holding period starts the day after purchase.
  • Short-term gains can push your total income into a higher tax bracket, raising the rate you pay on the gain itself.
  • You report short-term gains on Schedule D and Form 8949, and they count toward your total taxable income for the year.
  • Holding an investment just over one year can save you thousands in tax by moving the gain into the long-term category.

How your tax bracket determines what you owe

Your short-term capital gain is added to your other income for the year — wages, interest, dividends, self-employment income — and taxed at whatever bracket that total falls into. If you earn $60,000 in salary and realize a $20,000 short-term gain, you're taxed on $80,000 total.

For 2024, a single filer in the 22% bracket with $60,000 in wages who takes a $20,000 short-term gain will owe tax on that gain at 22%, not a lower rate. But if the gain pushes total income above $47,025 (the top of the 22% bracket for single filers), part of the gain gets taxed at 24%. This "bracket creep" is why a large short-term gain can feel more expensive than you calculated.

The brackets change each year for inflation. The IRS publishes new brackets in October for the following tax year, so check the current year's brackets on IRS.gov or your tax software before estimating what you'll owe.

The difference between short-term and long-term rates

Long-term capital gains — investments held over one year — are taxed at preferential rates: 0%, 15%, or 20%, depending on your income. These rates are much lower than ordinary income brackets and don't change year to year. A $20,000 long-term gain might be taxed at 15%, while the same gain held short-term could be taxed at 24% or higher.

The gap widens for higher earners. If you're in the 37% ordinary bracket, a short-term gain is taxed at 37%. The same gain held long-term would be taxed at 20% — a difference of 17 percentage points. On a $50,000 gain, that's $8,500 in additional tax.

This is why timing matters. If you're close to the one-year mark, waiting a few weeks or months can move a gain from short-term to long-term and cut your tax bill significantly. However, if the investment is likely to fall in value, holding it longer to get the better rate may not make financial sense.

How to report short-term gains on your tax return

You report short-term capital gains on Schedule D (Capital Gains and Losses) and Form 8949 (Sales of Capital Assets). Form 8949 lists each transaction — the date bought, date sold, cost basis, and proceeds. Schedule D summarizes your totals and calculates net gain or loss.

Your brokerage sends you a Form 1099-B (Proceeds from Broker and Barter Exchange Transactions) showing sales proceeds. Use this to fill out Form 8949. If your brokerage also tracked cost basis, they'll report it on the 1099-B; if not, you'll need your own records.

Short-term gains and losses are netted together first. If you have $15,000 in short-term gains and $5,000 in short-term losses, you report a net $10,000 short-term gain. You can then use any excess short-term losses to offset long-term gains, or up to $3,000 of net losses against ordinary income in that year.

When short-term losses help reduce your tax bill

Short-term losses are valuable because they offset short-term gains dollar-for-dollar, and any excess can reduce your ordinary income. If you have $20,000 in short-term gains and $8,000 in short-term losses, you report $12,000 in net short-term gain. The $8,000 loss saved you tax at your ordinary rate — potentially 22%, 24%, or higher.

If losses exceed gains, you can deduct up to $3,000 of net capital loss against wages, salary, and other ordinary income in a single year. Any loss beyond $3,000 carries forward to future years with no time limit, so you can use it eventually.

This is the basis of tax-loss harvesting — selling a losing position to realize the loss, then buying a similar (but not identical) investment to stay in the market. The loss offsets gains or income now, and you maintain your market exposure. The IRS "wash sale" rule prevents you from buying the same or substantially identical security within 30 days before or after the sale, so timing and security selection matter.

State and local taxes on short-term gains

Federal tax is only part of the picture. Most states tax capital gains as ordinary income, adding another 3% to 13% depending on where you live. A few states — including Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, and Wyoming — have no state income tax at all. Others, like California and New York, tax capital gains at rates above 10%.

Some states have special rates for long-term gains. North Carolina, for example, taxes long-term gains at a lower rate than ordinary income. Check your state's tax agency website or ask a tax professional what rate applies to your situation.

If you live in a city with local income tax — Philadelphia, Columbus, Kansas City, and others — you may owe local tax on capital gains as well. This can add another 1% to 3% to your bill.

Strategies to manage short-term gains

If you know you'll have a large short-term gain, consider whether waiting a few more weeks or months to reach the one-year mark makes sense. The tax savings often justify the risk of price movement, especially if the investment is stable or you believe it will appreciate further.

Bunching gains and losses is another approach. If you're selling multiple positions, try to realize losses in the same year as large gains to offset them. If you have a year with unusually high income, it may be worth deferring a short-term gain sale to the following year when your bracket is lower.

For frequent traders, the math is harder. Day traders and active investors often have many short-term gains and losses. If you trade frequently and have a net loss for the year, you can deduct only $3,000 against ordinary income, and the rest carries forward. Some traders elect Section 475 mark-to-market accounting with the IRS, which treats all positions as sold on December 31 each year and allows full loss deductions, but this is complex and requires professional guidance.

Frequently Asked Questions

Can I avoid short-term capital gains tax by holding the investment just over one year?

Yes. If you hold an investment for more than one year, the gain becomes long-term and is taxed at preferential rates (0%, 15%, or 20%) instead of your ordinary rate. The holding period starts the day after you buy, so if you purchase on January 15, you can sell on January 16 of the next year and may have access to for long-term treatment. The tax savings often justify waiting a few weeks.

What if I have more short-term losses than gains?

You can deduct up to $3,000 of net capital loss against your ordinary income in a single year. Any loss beyond $3,000 carries forward to future years indefinitely. So a $10,000 net short-term loss lets you deduct $3,000 this year and $3,000 each of the next two years, with $1,000 left to carry forward further.

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

Yes. All capital gains, regardless of size, must be reported on your tax return. Your brokerage reports sales to the IRS on Form 1099-B, so the IRS knows about the transaction. Failing to report it can trigger an audit or penalty.

How does a short-term gain affect my may be able to access for tax credits or deductions?

Short-term gains count as taxable income and can push you into a higher tax bracket or above income limits for certain credits and deductions. For example, if a short-term gain raises your modified adjusted gross income above the threshold for the Earned Income Tax Credit or education credits, you may lose part or all of those benefits. Run the numbers before selling.

Is there a way to defer short-term capital gains tax?

Not directly. You owe tax in the year you sell, not when you reinvest the proceeds. However, you can defer the sale itself to the following year, which defers the tax. Some investors use opportunity zones to defer gains on new investments, but this is complex and requires professional guidance. For most people, the simplest approach is to hold short-term positions longer or use losses to offset gains.
