Section 1256 options are taxed under a fixed 60/40 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. Every open contract is also marked to market on the last business day of the tax year, so gains cannot be deferred by holding past December 31. For a trader in the top federal bracket, the split produces a blended effective rate of roughly 26.8% on net gains, compared with 37% if the same profit were taxed entirely as short-term.
Which Options Qualify
The statute lists five categories of Section 1256 contracts: regulated futures contracts, foreign currency contracts, nonequity options, dealer equity options, and dealer securities futures contracts.1Office of the Law Revision Counsel. 26 U.S. Code 1256 – Section 1256 Contracts Marked to Market For ordinary retail traders, the category that matters is nonequity options.
The statute defines a nonequity option as any listed option that is not an equity option. An equity option is one to buy or sell stock, or an option based on a narrow-based stock index. In practice, nonequity options are listed options on broad-based indexes, commodities, and debt instruments.
Index Options vs. ETF Options
This is where most confusion arises. Options on a broad-based index like the S&P 500 (SPX) qualify for Section 1256 treatment because they are cash-settled nonequity options based on a broad market index.2Cboe Global Markets. Index Options Benefits Tax Treatment Options on an ETF that tracks the same index do not. SPY is a fund made up of actual shares, so SPY options are equity options taxed under ordinary capital gains rules based on your holding period. The same split runs down the line: NDX options qualify, QQQ options do not.
The practical consequence is significant. A trader who buys and sells SPX options within a few days gets 60% of any profit taxed at the long-term rate. A trader doing the exact same thing with SPY options pays the full short-term rate on the entire gain.
Crypto Futures and Their Options
CME-listed Bitcoin and Ether futures qualify as regulated futures contracts, and options on those CME-listed crypto futures qualify as nonequity options. Both get the full 60/40 split and mark-to-market treatment. Crypto derivatives traded on offshore or unregulated platforms do not qualify, and spot crypto falls outside Section 1256 entirely. The treatment is tied to where and how the contract is traded, not to the underlying asset.
How the 60/40 Split Works
After the mark-to-market rule is applied, every dollar of net gain or loss from Section 1256 contracts is split automatically: 60% long-term, 40% short-term.1Office of the Law Revision Counsel. 26 U.S. Code 1256 – Section 1256 Contracts Marked to Market Your actual holding period is irrelevant. A position held for three hours gets the same split as one held for three months.
Say you are in the top federal bracket (37% on ordinary income, 20% on long-term capital gains) and realize $100,000 in net gains on SPX options over the year. Under standard short-term rules, the entire $100,000 would be taxed at 37% for $37,000 in federal tax. Under the 60/40 rule, $60,000 is taxed at 20% ($12,000) and $40,000 at 37% ($14,800), totaling $26,800. That is $10,200 less on the same profit.3Internal Revenue Service.

Higher-income taxpayers should also factor in the 3.8% Net Investment Income Tax, which applies to investment income above $200,000 for single filers or $250,000 for married couples filing jointly.4Internal Revenue Service. Questions and Answers on the Net Investment Income Tax NIIT applies to Section 1256 gains the same way it applies to other investment income. With the surtax included, the maximum effective federal rate on Section 1256 gains reaches about 30.6%, still well below the 40.8% that would apply to short-term gains taxed as ordinary income plus NIIT.
Mark-to-Market at Year End
Every Section 1256 contract you still hold on the last business day of the tax year is treated as if you sold it at fair market value on that day.1Office of the Law Revision Counsel. 26 U.S. Code 1256 – Section 1256 Contracts Marked to Market You recognize the gain or loss for the year even though you never closed the position, and your basis resets to that year-end value going into the new year.
Suppose you bought an SPX option for $5,000 and it was worth $7,500 on December 31. You report $2,500 of gain for the year, and your new basis becomes $7,500. 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. The wash sale rules are written to cover shares of stock or securities, and Section 1256 contracts fall outside that definition. The mark-to-market mechanism also makes wash sales conceptually irrelevant, because all unrealized gains and losses are already being recognized at year-end. You can close losing positions and immediately reenter similar positions near year-end without worrying about loss disallowance.
Reporting on Form 6781 and Schedule D
You report Section 1256 results 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 brokerage typically reports a single net figure on Form 1099-B, which you enter into Part I of Form 6781. The form applies the 60/40 split mechanically and produces two numbers: a short-term amount (40% of the net) and a long-term amount (60%).
Those figures transfer directly to Schedule D. The 40% short-term portion goes on line 4 of Schedule D, and the 60% long-term portion goes on line 11.6Internal Revenue Service. Form 6781 – Gains and Losses From Section 1256 Contracts and Straddles From there they combine with all your other capital gains and losses. If the combined result is a net loss, the standard capital loss deduction limit of $3,000 per year ($1,500 if married filing separately) applies.7Office of the Law Revision Counsel. 26 U.S. Code 1211 – Limitation on Capital Losses
Carrying a Section 1256 Loss Back
Section 1256 contracts have a loss carryback rule that ordinary stock losses do not. If you have a net Section 1256 loss for the year, you can elect to carry it back up to 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 prior years, not stock gains or other income. Losses must be applied to the earliest year first, with any excess rolling forward within the three-year window.
The carryback keeps its 60/40 character: 60% long-term loss, 40% short-term. The carryback cannot create or increase a net operating loss in the prior year.
To claim it, file Form 1045 (Application for Tentative Refund) within one year after the end of the loss year, or file an amended return for the prior year.9Internal Revenue Service. Instructions for Form 1045 Form 1045 is generally faster because the IRS is required to process it within 90 days.
Where Section 1256 Treatment Does Not Apply
A few situations look like they should fall under Section 1256 but do not, and each has its own rules worth flagging.
If you use a Section 1256 contract as a hedge and identify it as such before the close of the day you enter the position, the contract is pulled out of the normal 60/40 and mark-to-market framework.10eCFR. 26 CFR 1.1256(e)-1 – Identification of Hedging Transactions Gains and losses become ordinary rather than capital. Ordinary loss treatment escapes the $3,000 cap, but ordinary gain treatment loses the 60/40 benefit. The identification deadline is strict; miss it and the contract stays under normal Section 1256 rules even if it was economically a hedge.
A mixed straddle exists when you hold offsetting positions and at least one is a Section 1256 contract while at least one is not, such as long SPX index options paired with a short position in an S&P 500 ETF. Special elections under Section 1092 govern how the offsetting legs are matched, and the loss deferral rule means you can only recognize a loss to the extent it exceeds unrecognized gain on the offsetting side.11Office of the Law Revision Counsel. 26 USC 1092 – Straddles
Retail spot forex is taxed by default under Section 988 as ordinary income or loss. Certain forex traders can elect out of Section 988 into Section 1256 treatment, but the election must be made affirmatively before the first day of the tax year; you cannot decide retroactively based on how the year turned out.
