How futures profits are taxed in the US: Section 1256 and the 60/40 rule

You and your neighbor each clear $10,000 trading this year. She day-trades stocks; you trade micro index futures. Same profit, same twelve months. If you are both in the 32% bracket, her federal bill on that money is about $3,200 and yours is about $2,180.

Nothing in that $1,020 gap has to do with skill. It is a line in the tax code called Section 1256, and most futures traders learn about it after their first year instead of before.

What Section 1256 actually covers

Section 1256 defines a category called Section 1256 contracts. The one that matters here is the regulated futures contract: a futures contract traded on a qualified board or exchange, which in practice means the CME and its peers. The E-mini and Micro E-mini index futures a trading bot would trade are regulated futures contracts.

The category also takes in foreign currency contracts and non-equity options. It does not include shares, ETFs, options on individual stocks held by a non-dealer, or most crypto products that do not trade on a qualified US exchange.

The structural point: you do not elect into this. No form to file, no trader tax status to qualify for, no minimum trade count. If the contract qualifies, the treatment applies. That is unusual in a code where favorable treatment normally has to be claimed.

The 60/40 rule, and the arithmetic behind it

The rule in one sentence: 60% of your net gain or loss on Section 1256 contracts is treated as long-term capital gain or loss and 40% as short-term, regardless of holding period.

Read that last clause again. A futures trade held four minutes gets 60% long-term treatment. A stock held eleven months gets none.

Work the numbers. You net $10,000 on index futures, in the 32% ordinary bracket with a 15% long-term rate:

• $6,000 long-term at 15% = $900
• $4,000 short-term at 32% = $1,280
• Total $2,180, an effective rate of 21.8%

The same $10,000 from day-trading stocks is entirely short-term at 32%: $3,200. At the top of the brackets the gap is starker. A 37% ordinary rate against a 20% long-term rate blends to 0.60 × 20% + 0.40 × 37% = 26.8%, against 37% flat. Ten points of tax on the same dollar, for using a different instrument.

Two caveats a CPA will raise. The 3.8% net investment income tax can sit on top once your income clears the thresholds, and state income tax generally ignores the 60/40 split entirely, so this is a federal advantage only.

Holding period is the whole game in stocks. In futures it does not exist.

Mark-to-market: December 31 settles your open positions 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 in that year, and the contract's basis is adjusted so the same move is not taxed twice when you actually close it. That is a real difference from stocks, where an unrealized gain is nobody's business until you sell, and it can be unwelcome: you can owe tax on a gain you have not taken and might give back in January.

Stocks and futures, side by side

Form 6781, and where your number actually goes

Your futures broker sends a Form 1099-B, but it does not look like a stock 1099-B. Instead of a list of every trade, the regulated futures section carries a small block of boxes ending in an aggregate profit or loss on contracts figure: realized results plus the mark-to-market adjustment on anything open, in one number.

That number goes on Form 6781, Gains and Losses From Section 1256 Contracts and Straddles. Part I is where a retail futures trader lives: you enter the gain or loss, the form nets it and splits it on two lines (40% short-term, 60% long-term), and both flow onto Schedule D.

Losses: the $3,000 wall, and the carryback that gets around it

Now the part a sales page skips. Section 1256 results are capital gains and losses, and capital losses hit a hard ceiling against ordinary income: $3,000 per year ($1,500 married filing separately). Everything above that carries forward until you have gains to absorb it.

Finish $20,000 down with no other capital gains and you deduct $3,000 this year and carry $17,000 forward, almost six more years to work off if you never trade again. That is the honest counterweight to 60/40: the code is generous with futures gains and stingy with futures losses.

Section 1256 gives you one exit stock traders do not have. You can elect to carry a net Section 1256 contract loss back three years, where it offsets net Section 1256 gains from those years only, earliest year first. You make the election by checking box D on Form 6781 for the loss year, then claim the refund on amended returns for the earlier years.

Concretely: if you netted $20,000 of futures gains two years ago and paid tax on it, and lose $20,000 now, the carryback recovers that tax immediately instead of grinding it out at $3,000 a year. Anything the earlier years cannot absorb carries forward as a normal capital loss. There are ordering rules and limits, so this is a CPA conversation, and one to have in the year the loss happens, not the year after.

What to actually ask a CPA

1. "My broker sent a 1099-B with an aggregate profit or loss figure. Are we filing Form 6781?" This tells you in ten seconds whether they have done this before.
2. "Which of my trading costs are deductible, and where do they go?" The rules here have changed more than once recently.
3. "Do I have prior-year Section 1256 gains that would make the box D carryback worth it, and what should I be paying quarterly?" Ask both before you need the answers.

And a third time, because this is the article where it matters most: none of the above is tax advice. It is a map of the terrain so you can have a useful conversation with someone licensed to advise you. The rest of the picture is in the complete guide to trading bots and on the risk page.

Frequently asked questions

Do I need trader tax status to get the 60/40 split on futures?

No. Section 1256 treatment applies automatically to regulated futures contracts regardless of how many trades you make or whether the IRS would consider you a trader or an investor. Trader tax status is a separate question affecting how you deduct expenses and whether a Section 475 election is available. Worth discussing with a CPA, but not a prerequisite for 60/40.

Does the wash sale rule apply to futures?

The wash sale rule does not apply to Section 1256 contracts. That is one of the quieter advantages of futures: you can take a loss in December and be back in the same contract in January without a disallowed loss following you around. Because open positions are marked to market at year end anyway, the behavior the rule exists to police mostly does not arise. Confirm how this interacts with other positions you hold before acting on it.
