Day trading profits are taxed as short-term capital gains, which means at your ordinary federal income tax rate. For 2026, that rate runs from 10% to 37%, depending on your total taxable income. High earners may owe another 3.8% net investment income tax, and most states, including California, tax the gains as well.
Below are the 2026 brackets and the loss rules that catch many traders. You will also find the special IRS trader status and a worked example you can use as a simple calculator.
Why day trading gains are short-term
The IRS splits capital gains by holding period. An asset held one year or less produces a short-term gain, and one held longer produces a long-term gain. Because day traders close positions the same day, nearly all of their profit is short-term.
That matters, since short-term gains get no special rate. They are added to your wages and other income and taxed in your normal brackets. Long-term gains, by contrast, are taxed at 0%, 15% or 20%. For 2026, the 0% rate covers taxable income up to $49,450 for single filers. The joint-filer limit is $98,900, according to IRS Revenue Procedure 2025-32. Day traders rarely benefit from those lower rates.
If you are still deciding whether to trade this way, our explainer on what day trading is covers the basics first.
2026 federal tax brackets for short-term gains
These are the ordinary income brackets for tax year 2026, the year you will file for in early 2027. The figures apply to taxable income, which is income after deductions. The 2026 standard deduction is $16,100 for single filers and $32,200 for joint filers.
| Rate | Single filers | Married filing jointly |
|---|---|---|
| 10% | Up to $12,400 | Up to $24,800 |
| 12% | $12,401 to $50,400 | $24,801 to $100,800 |
| 22% | $50,401 to $105,700 | $100,801 to $211,400 |
| 24% | $105,701 to $201,775 | $211,401 to $403,550 |
| 32% | $201,776 to $256,225 | $403,551 to $512,450 |
| 35% | $256,226 to $640,600 | $512,451 to $768,700 |
| 37% | Over $640,600 | Over $768,700 |
On top of these rates, the net investment income tax adds 3.8% when modified adjusted gross income passes $200,000 for single filers or $250,000 for joint filers, as described in IRS Topic 559. Those thresholds are set by law and are not adjusted for inflation.
A worked example: estimating your day trading tax
Online day trading tax calculators all follow the same logic, so you can run the numbers by hand. Here is a simple case for 2026.
A single filer earns a $70,000 salary and ends the year with $20,000 in net short-term trading gains. Total income is $90,000. After the $16,100 standard deduction, taxable income is $73,900.
- The salary alone fills taxable income up to $53,900.
- The $20,000 of gains sits on top, from $53,900 to $73,900.
- That whole slice falls in the 22% bracket, so federal tax on the gains is about $4,400.
If the same $20,000 had been a long-term gain, it would have been taxed at 15%, or $3,000. So holding period alone changes the bill by about $1,400 here. State tax comes on top. California, for instance, has no lower rate for capital gains. It taxes them as regular income at 1% to 12.3%, plus 1% on income over $1 million.
To estimate your own bill, start with your expected taxable income without trading. Then add your net gains and see which brackets they land in. After that, add state tax and, if your income is high, the 3.8% surtax.
Losses and the wash sale rule
Losing trades offset winning ones. If losses beat gains for the year, you can deduct up to $3,000 of the net loss against other income. The limit is $1,500 if married filing separately. Anything beyond that carries forward to future years, according to IRS Topic 409.
The wash sale rule is where day traders often get surprised. Say you sell a stock at a loss. If you buy the same or a substantially identical security within 30 days before or after, that loss is disallowed for now. Instead, it is added to the cost basis of the new shares. Since day traders often trade the same tickers again and again, many of their losses get deferred this way.
For example, say you lose $500 on a stock on Monday and buy it back on Wednesday. You cannot claim the $500 yet. Your new shares carry a basis $500 higher. So the loss shows up later, once you sell and stay out for 30 days. The catch is a year-end wash sale, which can push a loss into the next tax year.
Trader tax status and the mark-to-market election
The IRS treats a small group of people as traders in securities, which works like running a business. Under IRS Topic 429, you qualify only if you seek profit from daily price moves rather than dividends or growth. Your activity must also be substantial, continuous and regular. The IRS looks at holding periods, the number and size of trades, time spent and whether trading is your livelihood. Simply calling yourself a day trader does not count.
Qualifying traders can deduct business expenses, such as data feeds and software, on Schedule C. Their gains and losses are still capital, though, so the $3,000 limit and the wash sale rule still apply. Trading gains are not subject to self-employment tax.
Traders can also make a Section 475(f) mark-to-market election. With it, gains and losses become ordinary and go on Form 4797. They also escape both the $3,000 cap and the wash sale rule. The downside is that gains lose any chance at long-term rates, and the choice is hard to undo. The election is due by the original due date of the prior year’s return. So for tax year 2027, the deadline is the 2026 return’s due date, normally April 15, 2027. Late elections are not allowed.
Reporting and paying during the year
Your broker sends Form 1099-B early in the year, listing proceeds, cost basis and wash sale adjustments. You report trades on Form 8949 and Schedule D, unless you made the mark-to-market election.
Taxes are not withheld from trading profits. So if you expect a large gain, you may need to make quarterly estimated payments. For 2026 income, the dates are April 15, June 15 and September 15, 2026, and January 15, 2027. The IRS pay-as-you-go guide explains how to avoid an underpayment penalty. Generally, you pay at least 90% of this year’s tax or 100% of last year’s. That second figure rises to 110% if your prior-year income was above $150,000.
