Futures taxes explained: how Section 1256 works for US traders

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.

What Section 1256 actually covers

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 60/40 rule, in plain English

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.

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.

Mark-to-market: December 31 does your accounting for you

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.

Form 6781: the paperwork is short

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.

Losses, and the one exit stocks do not get

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.

Frequently asked questions

What is Section 1256 and does it apply to index futures?

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.

How does the 60/40 rule lower my taxes?

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.

Do I have to hold futures for a year to get long-term treatment?

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.

Is this tax advice?

Educational content, not investment advice. Trading futures involves substantial risk of loss and is not suitable for every investor.
