Section 1256 Tax Treatment for ES and NQ Futures: The 60/40 Rule, Year-End Marking and Form 6781

ES, NQ and the other CME index futures are generally Section 1256 contracts, so their gains and losses are treated as 60% long-term and 40% short-term, no matter how long you held the position. Any contract still open at year-end is treated as sold at its market value on the last business day of the year, and everything is reported on Form 6781. For an active trader, that can mean a lower federal rate than the same profit taxed entirely as short-term gain.

This guide explains which contracts qualify, how the 60/40 split and year-end marking work, what happens with losses, and how the numbers reach your return. It is general education, not tax advice. Rules and rates can change, so confirm how they apply to you with a qualified tax professional.

Which contracts qualify

Section 1256 of the Internal Revenue Code covers several types of contract. The two that matter here are regulated futures contracts and nonequity options. IRS Publication 550 describes a regulated futures contract as one that is marked to market daily and traded on a qualified exchange, and it lists broad-based stock index options as nonequity options, naming the S&P 500 as an example.

Instrument	Section 1256?
ES, NQ, RTY, YM and their micros	Generally yes
SPX and other broad-based index options	Generally yes
Options on ETFs, such as SPY and QQQ	Generally no
Stocks and stock options	No

The ETF line surprises many traders. SPY tracks the same index as SPX, but Cboe’s comparison notes that SPY option gains held under a year are taxed as short-term, while S&P 500 index options can qualify for 60/40. If you trade ES alongside options, you may have two sets of tax rules in one account. Our comparison of ES futures and SPX options covers the other differences between them.

How the 60/40 rule works

Under Section 1256, gain or loss on a qualifying contract is treated as 40% short-term and 60% long-term. Publication 550 says this applies regardless of how long you held it, so a trade held for 90 seconds gets the same split as one held for six months.

The split matters because of how each part is taxed. Net short-term gains are taxed as ordinary income, while most long-term gains are taxed at 0%, 15% or 20%, depending on your taxable income.

Here is a simplified example using illustrative federal rates: a 24% ordinary rate and a 15% long-term rate. Say your net gain on ES for the year is $10,000.

Long-term part: 60% is $6,000, and $6,000 × 15% = $900.
Short-term part: 40% is $4,000, and $4,000 × 24% = $960.
Total: $1,860, or 18.6% of the gain.
If it were all short-term: $10,000 × 24% = $2,400.

At the top federal rates of 37% and 20%, the same arithmetic gives a blended rate of 26.8%. Your own rates depend on your income and filing status. These figures also leave out state income tax and the 3.8% net investment income tax, which can apply above certain income levels.

Year-end marking: open positions count

Section 1256 contracts follow a mark-to-market rule. Publication 550 says a contract you hold at the end of the tax year is generally treated as sold at its fair market value on the last business day of the year. You recognize that gain or loss on this year’s return, even though the position is still open.

Say you hold one ES contract over the year-end with an open gain of $3,000:

This year. You report the $3,000 gain, split 60/40, even though you haven’t closed the trade.
Next year. You close the trade in January with a total gain of $4,000. Because $3,000 was already reported, only $1,000 is next year’s gain.

The same rule works in reverse for an open loss, which you recognize this year. Most intraday traders are flat at year-end, so this mainly affects positions you hold overnight into January.

When you have a loss

A net loss on Section 1256 contracts is also split 60/40. Capital losses first offset capital gains, and Topic 409 limits any excess you can deduct against other income to $3,000 a year, or $1,500 if married filing separately. The rest carries forward.

Section 1256 traders also have a choice that stock traders don’t. Under Section 1212(c), an individual can elect to carry a net Section 1256 loss back three years. Publication 550 sets these limits:

The loss goes to the earliest of the three years first.
It can only offset net Section 1256 gains from those years, not other income.
It can’t create or increase a net operating loss in the earlier year.
Any amount not used carries forward under the normal rules.

You make the election on Form 6781 for the loss year, and you claim the carryback with Form 1040-X or Form 1045. If you never had Section 1256 gains in the prior three years, the election gives you nothing to offset.

Wash sales

Section 1256(f)(5) says the wash sale rule doesn’t apply to a loss recognized through year-end marking. Stocks, stock options and ETF options remain under the normal wash sale rules, so a mixed account still needs tracking. Ask your tax professional how these rules apply to any trades that combine futures with stocks or ETFs.

How it reaches your tax return

Your futures broker should send Form 1099-B, but it looks different from a stock statement. Contracts are summarized in four boxes, not listed trade by trade:

Box 8: profit or loss realized on closed contracts during the year.
Box 9: unrealized profit or loss on open contracts at the end of the prior year.
Box 10: unrealized profit or loss on open contracts at the end of this year.
Box 11: the aggregate profit or loss for the year, worked out from boxes 8, 9 and 10.

The box 11 figure goes on Part I of Form 6781, which splits the result 60/40. The two parts then go to Schedule D, on line 4 for short-term and line 11 for long-term. Attach Form 6781 to your return.

Nothing is withheld on futures gains. If you have a profitable year, check whether you need to make estimated tax payments, because the IRS can charge a penalty for underpayment.

Exceptions worth knowing

Hedges. Publication 550 says the mark-to-market rule doesn’t apply to qualifying hedging transactions. That definition is about business hedges, so don’t assume an ES position held against your portfolio counts. Our guide to hedging options with futures covers the trading side.
Straddles. Holding offsetting positions, such as ES against a stock or ETF position, can bring in separate straddle rules that change the timing of losses. Form 6781 has its own part for these.
Trader status. Topic 429 describes the requirements to be treated as a trader in securities and the Section 475(f) mark-to-market election, which generally makes gains and losses ordinary. Speak with a tax professional before making that election, because it has its own deadline and can change how your trading is taxed.

Common mistakes

Assuming all options get 60/40. SPX can qualify. SPY and QQQ generally don’t.
Forgetting open positions at year-end. An open gain counts this year, even if the trade later turns into a loss.
Treating the carryback as a general deduction. It only offsets prior Section 1256 gains.
Forgetting state tax. The 60/40 rule is a federal rule, so check how your state treats long-term gains.
Trading for the tax treatment. A lower rate on a gain doesn’t make a poor setup better. Choose the instrument for the trade first.

Frequently asked questions

Does the 60/40 rule apply to day trades?

Yes, for qualifying contracts. The split applies regardless of how long you held the position, so an intraday ES trade gets the same treatment as a position held for months.

Do micro futures qualify for Section 1256?

MES, MNQ, M2K and MYM trade on CME Group exchanges and are marked to market daily like their E-mini versions, so they are generally treated the same way. Check your Form 1099-B and confirm with your tax professional.

Do I owe tax on an open position at year-end?

Generally, yes. A contract held at year-end is treated as sold at its market value on the last business day, so an open gain or loss goes on this year’s return. Your later gain or loss is measured from that value.

Are SPY options Section 1256 contracts?

Generally not. SPY is an ETF, and its options follow the normal holding-period rules. Broad-based index options such as SPX can qualify.

Conclusion

Section 1256 treats ES and NQ gains as 60% long-term and 40% short-term regardless of how long you hold, marks open contracts at year-end, and offers a three-year carryback for losses. Know which of your instruments qualify, watch what you hold over December 31, and take your Form 1099-B to a tax professional.
