You bought 100 shares of a buzzy AI company in April at $50 per share. By November, it's at $100 and you're staring at a $5,000 profit. You sell. Seven months of ownership, a tidy double. Feels like a win.
Then tax season arrives. You're a single filer making $72,000 a year. That $5,000 gain gets taxed at 22%, same as your paycheck. You owe $1,100. Had you waited five more months, you'd have paid 15% instead, owing $750. That $350 difference is the cost of impatience.
Short-term capital gains tax is the penalty for selling too soon. And for many investors, it's a penalty they don't see coming until April.
The quick version: Sell any asset within one year and the profit gets taxed as ordinary income (10% to 37%). Wait past one year and you'll pay the lower long-term rates (0%, 15%, or 20%). The difference can be 7 to 17 percentage points.
What Counts as a Short-Term Capital Gain?
Any profit from selling an asset held for one year or less. Stocks, bonds, cryptocurrency, real estate, collectibles, even a car you flipped. If you bought it and sold it within 365 days for a profit, it's short-term.
The key distinction: short-term gains don't get preferential treatment. They're stacked on top of your wages and taxed at whatever marginal rate applies. No special bracket. No lower ceiling. No break of any kind.
For many people, short-term gains are their most expensive form of income. The same $10,000 profit that would cost $1,500 as a long-term gain might cost $2,400, $3,200, or even $3,700 as a short-term gain, depending on your bracket.
2026 Short-Term Capital Gains Tax Rates
Since short-term gains are taxed as ordinary income, here are the 2026 brackets that apply:
| Rate | Single | Married Filing Jointly | Head of Household |
|---|
| 10% | $0–$12,400 | $0–$24,800 | $0–$17,700 |
| 12% | $12,401–$50,400 | $24,801–$100,800 | $17,701–$67,450 |
| 22% | $50,401–$105,700 | $100,801–$211,400 | $67,451–$105,700 |
| 24% | $105,701–$201,775 | $211,401–$403,550 | $105,701–$201,775 |
| 32% | $201,776–$256,225 | $403,551–$512,450 | $201,776–$256,200 |
| 35% | $256,226–$640,600 | $512,451–$768,700 | $256,201–$640,600 |
| 37% | Over $640,600 | Over $768,700 | Over $640,600 |

Your short-term gains don't get their own bracket. They pile on top of your salary. Make $90,000 at work and sell stock for a $10,000 short-term gain? Your total income is $100,000, and that gain pushes you further into the 22% bracket (or even into 24% territory, depending on deductions).
The Real Cost: Short-Term vs. Long-Term, Side by Side
Numbers tell the story. Here are three scenarios for a single filer in 2026 with a $72,000 salary and a $5,000 gain:
| Scenario | Holding Period | Tax Rate | Tax Owed | Net Profit |
|---|
| Sold at 8 months | Short-term | 22% | $1,100 | $3,900 |
| Sold at 13 months | Long-term | 15% | $750 | $4,250 |
| Sold at 13 months (low income year) | Long-term, 0% bracket | 0% | $0 | $5,000 |
The gap between selling at 8 months and 13 months is $350 on a $5,000 gain. Scale that up to a fifty thousand dollar profit on a house flip or business sale, and the difference jumps to $3,500.
It gets worse for high earners. Someone in the 37% federal bracket selling short-term pays more than double what they'd pay at the 20% long-term rate. Add the 3.8% NIIT and state taxes, and the total hit in a state like California can exceed 50% of the gain.
The full rate tables for long-term gains are covered in our long-term capital gains rate guide.
States Make It Worse (or Better)
Most states tax short-term gains as ordinary income, same as the feds. But the rates vary wildly.
Massachusetts is particularly rough on short-term investors: it taxes short-term gains at 8.5%, compared to 5% for long-term gains. That's one of the few states with an explicit distinction between the two.
California adds up to 13.3% on top of federal rates, with no distinction between short and long-term. A day trader in San Francisco could face a combined rate north of 50% on short-term profits.
Living in Florida, Texas, or one of the other states with no income tax? Your short-term gains avoid state tax entirely. Check how your state taxes investment profits to see exactly where you stand.
When Selling Short-Term Actually Makes Sense
Wait, isn't it always better to hold? Not necessarily. Real life has edge cases, and sometimes the mathematically "right" move is to sell early.
The stock is tanking. If your investment is falling fast, waiting five more months for long-term treatment while losing $8,000 in value doesn't save you money. A $2,200 tax bill beats a $10,000 loss. Every time.
You need the cash. Medical bills, a down payment, or an opportunity that won't wait. Sometimes liquidity matters more than tax optimization. (I'd rather pay taxes on a gain than watch an emergency wipe out my savings.)
You're offsetting with losses. Have $5,000 in short-term gains and $5,000 in losses from other sales? They cancel out. No tax owed regardless of the holding period. Tax-loss harvesting is a powerful tool, and we walk through it in how selling losers lowers your tax bill.
You're in a low bracket. If your total income (including the gain) stays below $12,400 as a single filer, you're only paying 10%. That's close enough to the 0% long-term rate that the difference may not be worth the risk of holding longer.
The point isn't that short-term selling is always wrong. It's that you should know the cost before you hit "sell."
A Word About Crypto and Day Trading
Cryptocurrency gets no special treatment. The IRS classifies it as property, and every sale, swap, or purchase using crypto is a taxable event. Buy Bitcoin on Coinbase in January and trade it for Ethereum in June? That's a short-term gain (or loss) on the Bitcoin, taxed at ordinary rates.
Day traders face an even tougher reality. Every profitable trade within a year generates short-term gains. A trader who makes $50,000 in short-term profits and earns $80,000 in salary is looking at $130,000 of ordinary income. At that level, the marginal rate on the gains is 24%.
This is why serious traders use tax-advantaged accounts when possible. Trading inside a Roth IRA means zero capital gains tax on any profit, short or long-term. The catch: you can't day-trade on margin in an IRA, and contribution limits cap how much you can put in.
Your Next Move
- Check your unrealized positions. Look at the purchase dates in your brokerage account (Schwab, Fidelity, Robinhood, wherever). Any holding approaching the one-year mark deserves a pause before selling.
- Calculate the actual cost. Use our tax bracket calculator to see what your short-term gain would be taxed at versus long-term.
- Offset with losses. If you have unrealized losses elsewhere in your portfolio, selling those can neutralize your short-term gains. Remember the wash-sale rule: you can't buy back the same security within 30 days.
- Consider the full picture. Don't let a $350 tax savings stop you from taking a profit if the investment is deteriorating. Taxes are a cost of investing. Losing money is worse.
- Move active trading into tax-sheltered accounts. If you frequently buy and sell, a Roth IRA or traditional IRA eliminates the short-term/long-term distinction entirely.
