Here is a fact many futures traders learn a year too late: the profit you make trading US index futures is taxed under its own set of rules, and those rules are usually kinder than the ones that apply to stocks. The relevant part of the tax code is Section 1256, and this is the plain-English version of what it means, why it exists, and what paperwork it produces.
One thing up front, and it is not boilerplate: this is general information, not tax advice. It is here to help you ask a professional better questions, not to replace one who has seen your return. Rates change, and a blog post has never met your CPA.
US index futures get 60/40 tax treatment automatically: 60% of the gain is taxed at long-term rates and 40% at short-term rates, no matter how briefly you held the contract. You do not elect into it, and there is no holding period to satisfy. It usually lowers the bill, but money a prop firm pays you often sits outside it entirely.
Section 1256 of the Internal Revenue Code defines a category called Section 1256 contracts. The one that matters for this site is the regulated futures contract: a futures contract traded on a qualified US exchange, in practice the CME and its peers. The E-mini and Micro E-mini index futures that an automated system would trade are regulated futures contracts, so they fall squarely inside Section 1256. The category also covers certain foreign currency contracts and non-equity options, but not shares, ETFs, or most crypto that does not trade on a qualified US exchange.
The structural surprise is that you do not choose this. There is no form to opt in, no trader status to qualify for, no minimum number of trades. If the contract qualifies, the treatment applies by default, unusual in a code where good treatment normally has to be claimed.
The rule in one sentence: 60% of your net gain or loss on Section 1256 contracts is treated as long-term and 40% as short-term, regardless of how long you actually held anything.
That last clause is the gift. A futures trade held four minutes still gets 60% long-term treatment; a stock has to be held more than a year to get any. Long-term rates are lower than ordinary rates, so blending most of your gain into the lower bucket pulls your rate down.
Here is the arithmetic on a round, illustrative number. Suppose your net gain for the year on index futures is $15,000, and you are in a 32% ordinary bracket with a 15% long-term rate. This example is arbitrary, chosen for clean math, and is not a Algomyth result.
| Portion | Amount | Rate | Tax |
|---|---|---|---|
| Long-term (60%) | $9,000 | 15% | $1,350 |
| Short-term (40%) | $6,000 | 32% | $1,920 |
| Total | $15,000 | 21.8% blended | $3,270 |
That same $15,000 earned day-trading stocks would be entirely short-term at 32%, or $4,800. The 60/40 split saved about $1,530 on identical profit, purely because of the instrument, and at the top brackets the gap is wider. It is not a loophole, just how regulated futures are taxed. The companion article, how futures profits are taxed in the US, works the top-bracket math in more depth.
Any Section 1256 contract still open on the last business day of the year is treated as if you sold it at fair market value that day. The unrealized gain or loss becomes taxable that year, and the contract's basis is adjusted so the same move is not taxed twice when you close it. This is a real difference from stocks, where an unrealized gain is nobody's business until you sell, and it can sting: you might owe tax on a paper gain you have not banked.
But it is a non-issue for a system that goes home flat. The Algomyth engines close every position the same day they open it and never hold overnight, so on December 31 there is nothing open to mark. Understand the rule, then forget it.
One of the quiet advantages of Section 1256 is how little you file. Your futures broker sends a Form 1099-B, but unlike a stock 1099-B it does not list every trade: the regulated-futures section carries a small block of boxes ending in a single aggregate profit or loss figure for the year.
That one number goes on Form 6781, titled Gains and Losses From Section 1256 Contracts and Straddles. The form nets your result, splits it into the 40% short-term and 60% long-term lines, and both flow onto Schedule D. A year of index-futures trading, however many trades it took, is essentially one line, against hundreds or thousands of rows on Form 8949 for the same volume in stocks. The wash sale rule, for the record, does not apply to Section 1256 contracts.
The full backtest, the drawdowns and the costs are on one page, with a calculator to run the arithmetic on your own account size and assumptions.
The honest counterweight to 60/40 is that Section 1256 results are capital gains and losses, and capital losses offset only $3,000 of ordinary income per year, with the rest carried forward, the same wall stock traders hit. Where futures traders get an extra door is the three-year loss carryback: you can elect to carry a net Section 1256 loss back three years to offset Section 1256 gains you already paid tax on, and claim a refund. It is a genuine advantage in a bad year, with ordering rules that make it a CPA conversation; the mechanics are in the detailed tax article.
This is where careful people get their first year wrong. Most US futures prop firms do not give you an account in your own name. You buy an evaluation, trade an account the firm controls, and the firm pays you when you request a payout. Because you were never the account holder at the clearing broker, no futures 1099-B carries your name.
What usually arrives instead is a Form 1099-NEC or 1099-MISC, reporting the payouts as ordinary, contractor-style income, often on Schedule C and sometimes with self-employment tax on top. No 60/40, no Form 6781. It depends entirely on how the firm is structured, and a few do place funded traders in accounts in their own name where normal futures treatment applies. Ask what form your firm issues before you assume, and read how funded capital works and, on the legal side, whether automated trading is legal in the US.
Use it as a map, not as a return. Two questions get most retail futures traders where they need to be. First: "My broker sent a 1099-B with an aggregate profit or loss figure, so are we filing Form 6781?" Second, if you trade funded capital: "My prop firm sent a 1099-NEC, so is that Schedule C, and does self-employment tax apply?" Both have real dollars attached and are worth an hour of a professional's time. For everything between a profit on the screen and money in the bank, the prop firm trading guide is the wider context.
Section 1256 is the part of the US tax code that governs regulated futures contracts, among a few other instruments. E-mini and Micro E-mini US index futures are regulated futures contracts traded on a qualified exchange, so they fall under Section 1256 automatically, with 60/40 treatment and mark-to-market at year end and no election required. If you trade index futures, this is your tax framework whether you planned for it or not.
The 60/40 rule treats 60% of your net futures gain as long-term and 40% as short-term regardless of how long you held the contract. Long-term rates are lower than the ordinary rates that apply to short-term stock trades, so blending most of your gain into the lower bucket reduces your effective rate. On the same profit, a futures trader under 60/40 generally owes less than a stock day-trader whose gains are fully short-term, though the exact saving depends on your bracket.
No, and that is the whole point of the rule. The 60/40 split applies no matter how briefly you held the contract, so a futures trade opened and closed in the same minute still gets 60% long-term treatment. There is no holding period to satisfy and no election to make. This is the opposite of stocks, where holding period is everything and anything held under a year is fully short-term.
Usually not. If the firm owns the account and pays you under a contract, the payout is typically reported on a Form 1099-NEC or 1099-MISC as ordinary income, often on Schedule C, rather than as a Section 1256 capital gain. It depends on how the firm is structured, and some do move funded traders into accounts in their own name where normal futures treatment applies. Ask what tax form your firm issues, and take the agreement to a professional before year end.
No. This is general information written to help you understand the terrain and ask better questions, not advice about your specific return. Tax law changes, rates change, and your situation differs from the next reader's. Take the questions this article raises to a CPA who has seen your statements and any prop-firm agreement, and act on their answer rather than a blog post.
