Options classified as Section 1256 contracts are taxed under a special rule: 60% of any net gain or loss is treated as long-term capital gain or loss and 40% as short-term, no matter how briefly you held the position. For a trader in the top federal bracket, that blended treatment caps the effective rate at roughly 26.8%, compared with 37% if the same profit were taxed entirely as a short-term gain. The catch is that only certain options qualify, and the distinction between an index option and an option on an ETF tracking that same index decides whether you get the benefit.
Which Options Qualify
Section 1256 covers five categories of contracts, but for retail options traders the relevant one is the nonequity option.1Office of the Law Revision Counsel. 26 U.S. Code 1256 – Section 1256 Contracts Marked to Market The statute defines a nonequity option as any listed option that is not an equity option, and it defines an equity option as one to buy or sell stock or one based on a narrow-based stock index.
In practice, that means options on broad-based indexes, commodities, and debt instruments qualify. Options on individual stocks and on narrow-based stock indexes do not. Those stay under ordinary capital gains rules, where your actual holding period determines whether a gain is short-term or long-term.
SPX vs. SPY: The Index-Option Trap
This is where most traders get it wrong. Options on the S&P 500 Index (SPX) qualify for 60/40 treatment because they are nonequity options — cash-settled and based on a broad market index rather than on shares.2Cboe Global Markets. Index Options Benefits Tax Treatment Options on SPY, the exchange-traded fund tracking the same index, do not. SPY is a fund made up of actual shares, so options on it are equity options taxed under standard holding-period rules.
The dollar impact is real. A trader who buys and sells SPX options within a few days gets 60% of the profit taxed at long-term rates. A trader doing the same thing with SPY options pays short-term rates on the entire gain. For an active trader in a high bracket, the gap can run into thousands of dollars a year on the same strategy executed with the wrong ticker. The same logic separates NDX options (qualify) from QQQ options (do not).
How the 60/40 Split Works in Dollars
Once a position is in Section 1256, the split is automatic. Every dollar of net gain or loss for the year is divided 60% long-term, 40% short-term, with no minimum holding period and no action required on your part.
Take a top-bracket taxpayer (37% on ordinary income, 20% on long-term capital gains) with $100,000 in net SPX option gains for the year. Taxed entirely at the short-term rate, the bill is $37,000. Under 60/40, $60,000 is taxed at 20% ($12,000) and $40,000 at 37% ($14,800), for $26,800. That is $10,200 saved on the same profit.3Internal Revenue Service. IRS Form 6781 – Gains and Losses From Section 1256 Contracts and Straddles
Higher-income taxpayers also owe the 3.8% Net Investment Income Tax on investment income above $200,000 for single filers or $250,000 for married couples filing jointly, and that surtax applies to Section 1256 gains.4Internal Revenue Service. Questions and Answers on the Net Investment Income Tax With NIIT included, the top effective federal rate on Section 1256 gains comes to about 30.6%, still well below the 40.8% that would apply to short-term gains plus NIIT.
Mark-to-Market at Year-End
Every open Section 1256 position you hold on the last business day of the tax year is treated as sold at fair market value that day.1Office of the Law Revision Counsel. 26 U.S. Code 1256 – Section 1256 Contracts Marked to Market You recognize the resulting gain or loss for that year even though the position is still open. There is no way to defer a Section 1256 gain by holding past December 31.
When the new year starts, your basis resets to the year-end fair market value. Buy an SPX option for $5,000, mark it to $7,500 on December 31, and you report $2,500 of gain for that year. Your basis becomes $7,500, and if you close in February for $8,000, you report only $500 of additional gain in the new year.
One useful side effect: the wash sale rules under Section 1091 do not apply to Section 1256 contracts. Those rules are written for stock and securities, and the mark-to-market mechanism makes wash sales conceptually moot since all unrealized gains and losses are already recognized at year-end. You can close a losing Section 1256 position and re-enter a similar one near December 31 without worrying about loss disallowance.
Reporting on Form 6781
Section 1256 results are reported on IRS Form 6781, Gains and Losses From Section 1256 Contracts and Straddles.5Internal Revenue Service. About Form 6781, Gains and Losses From Section 1256 Contracts and Straddles Your broker will typically report a single net figure on Form 1099-B. You enter that in Part I of Form 6781, and the form applies the 60/40 split for you.
The two outputs flow to Schedule D: the 40% short-term portion to line 4, and the 60% long-term portion to line 11.6Internal Revenue Service. Form 6781 – Gains and Losses From Section 1256 Contracts and Straddles They then combine with your other capital gains and losses from stocks and other investments. If the combined result is a net capital loss, the normal $3,000 annual deduction limit against ordinary income applies ($1,500 if married filing separately).7Office of the Law Revision Counsel. 26 U.S. Code 1211 – Limitation on Capital Losses
Carrying Section 1256 Losses Back Three Years
Section 1256 offers something ordinary stock losses do not: a three-year carryback. If you have a net Section 1256 contracts loss for the year, you can elect to carry it back to any of the three preceding tax years.8Office of the Law Revision Counsel. 26 USC 1212 – Capital Loss Carrybacks and Carryovers The carryback can only offset Section 1256 gains reported in those earlier years, not stock gains or other income. It applies to the earliest eligible year first, and any excess rolls forward within the three-year window.
The 60/40 character carries over too. When you carry a loss back, 60% is treated as long-term and 40% as short-term in the prior year. One guardrail: the carryback cannot create or enlarge a net operating loss in the year it is applied to.
To claim it, file Form 1045 (Application for Tentative Refund) within one year after the end of the loss year, or amend the prior-year return.9Internal Revenue Service. Instructions for Form 1045 Form 1045 is usually faster because the IRS has to process it within 90 days, which makes the carryback a practical way to recover taxes paid on prior-year Section 1256 gains after a bad year.
Situations Where the Normal Rules Change
A few scenarios take Section 1256 options out of the standard 60/40 framework. If you use a qualifying contract as a hedge against risk on property you hold or liabilities you owe, and you identify the position as a hedge before the close of the day you enter it, gains and losses are treated as ordinary income rather than capital gain, and the mark-to-market rule drops away.10eCFR. 26 CFR 1.1256(e)-1 – Identification of Hedging Transactions The identification deadline is strict; miss it and the contract stays under normal Section 1256 rules even if it was economically a hedge.
If you hold offsetting positions where at least one is a Section 1256 contract and at least one is not (for example, long SPX options against short SPY shares), you have a mixed straddle, and the Section 1092 loss-deferral rules apply.11Office of the Law Revision Counsel. 26 USC 1092 – Straddles You can only recognize a loss on one leg to the extent it exceeds unrecognized gain on the offsetting leg. Available elections to coordinate the two sides generally lock in for all future years, so the cleanest approach is usually to keep Section 1256 and non-1256 positions in separate strategies.
For cryptocurrency options, qualification depends on venue. Options on CME-listed Bitcoin and Ether futures qualify as nonequity options because the CME is a qualified U.S. board or exchange. Crypto options on offshore or unregulated platforms do not qualify and fall under standard capital gains rules.
Retail spot forex is governed by Section 988 and taxed as ordinary income by default; a trader can elect out of Section 988 into Section 1256, but that election must be made prospectively, before the first day of the tax year, and once made it converts losses into capital losses capped at $3,000 per year.
