Section 1256 Contracts — The 60/40 Rule for Futures, Options, and Currency Trading

If you trade futures contracts, index options, foreign currency contracts, or certain other financial instruments, your gains and losses are taxed under a special regime that differs from ordinary stock or option trading in two critical ways. First, you are required to "mark to market" at year end — you owe tax on unrealized gains as if you sold every open position on December 31, whether you actually closed those positions or not. Second, regardless of how long you actually held the contracts, 60% of your net gain or loss is automatically treated as long-term capital gain or loss, and 40% is treated as short-term — the so-called "60/40 rule." This blended rate is usually significantly better than the pure short-term rate that applies to stocks held under a year, making Section 1256 contracts attractive to active traders. An additional perk: losses from Section 1256 contracts can be carried back three years (not just forward), letting you recover taxes you paid in prior years.

Current Law (2026)

Legal Authority

• 26 U.S.C. § 1256(a) — The mark-to-market and 60/40 rules: each Section 1256 contract held at year end is treated as sold at FMV; gain or loss is taken into account for the taxable year; 40% of gain/loss is short-term, 60% is long-term
• 26 U.S.C. § 1256(b) — Definition of Section 1256 contracts: (1) regulated futures contracts, (2) foreign currency contracts, (3) nonequity options, (4) dealer equity options, (5) dealer securities futures contracts; excludes individual stock options and most OTC derivatives
• 26 U.S.C. § 1256(c) — Mid-year dispositions: the mark-to-market rules also apply when you terminate, transfer, or offset a position during the year — proper adjustment is made to prevent double-counting
• 26 U.S.C. § 1256(d) — Election to treat net Section 1256 loss as a carryback: taxpayer may elect to carry back the net Section 1256 loss for the year to each of the 3 prior years, offset only against Section 1256 gains in those years; excess carries forward
• 26 U.S.C. § 1256(e) — Mixed straddle election and other special rules for straddles that combine Section 1256 and non-Section 1256 positions
• 26 U.S.C. § 1256(g) — Detailed definitions: "regulated futures contract" means a contract that requires delivery of a commodity or is settled by payment of cash; "foreign currency contract" means a contract requiring delivery or cash settlement of a foreign currency traded in an active interbank market

What Qualifies as a Section 1256 Contract

Regulated futures contracts: Commodity futures traded on CFTC-designated exchanges — corn, wheat, soybeans, crude oil, natural gas, gold, silver, coffee, cocoa, sugar, live cattle, lean hogs. Also financial futures: S&P 500 futures, Nasdaq-100 futures, T-bond futures, Eurodollar futures, bitcoin futures traded on CME. The exchange-traded requirement is key.

Nonequity options: Index options — SPX options (S&P 500 cash-settled), NDX options (Nasdaq-100), RUT options (Russell 2000), VIX options. These cash-settle against an index, not against shares of stock or an ETF, and therefore qualify as Section 1256 contracts. SPY options (options on the S&P 500 ETF, which is an equity) are NOT Section 1256 contracts.

Foreign currency contracts: Spot forex contracts traded in the interbank market, provided the taxpayer can elect into Section 1256 treatment (some forex income goes through § 988 instead — taxpayers can elect out of § 988 and into § 1256 for favorable 60/40 treatment, but must make the election before entering transactions).

What does NOT qualify:

• Options on individual stocks (Apple, Tesla, etc.) — these are equity options, not Section 1256
• Options on ETFs (SPY, QQQ, IWM) — ETF options are treated as equity options
• Interest rate swaps, credit default swaps, equity swaps
• Securities futures contracts on individual stocks

The Tax Advantage of the 60/40 Rule

For an active trader, the 60/40 rule is a meaningful benefit. Compare:

A trader in the 37% ordinary income bracket who makes $100,000 in short-term gains from:

• Stock options (non-Section 1256): $100,000 × 37% = $37,000 tax
• SPX index options (Section 1256): $60,000 × 20% LTCG + $40,000 × 37% = $12,000 + $14,800 = $26,800 tax

The Section 1256 trader saves $10,200 on the same profit. At higher profits, the savings compound.

The blended rate for a taxpayer in the top brackets (37% ordinary, 20% LTCG + 3.8% NIIT) works out to approximately: 60% × 23.8% + 40% × 40.8% = 14.28% + 16.32% = 30.6% blended rate on Section 1256 gains, versus 40.8% on identical short-term gains.

Mark-to-Market at Year End

The mandatory mark-to-market rule creates a tax timing difference compared to stocks:

• If you hold an open futures position at December 31, you owe tax on any unrealized gain — even though you haven't closed the position or received any cash
• The tax basis of your position is stepped up to the marked FMV, so when you eventually close the position you only pay tax on gains since year end (adjustment prevents double taxation)
• Losses on open positions are similarly recognized at year end — giving you an immediate deduction even without closing the trade

Year-end tax planning implication: Unlike stock positions where you control realization timing precisely, Section 1256 contracts force recognition on December 31. A trader sitting on large unrealized Section 1256 gains cannot defer tax into next year by simply holding through year end — the gain is recognized. Conversely, unrealized losses provide automatic year-end deductions.

Section 1256 Loss Carryback

One of the most valuable features: Section 1256 net losses can be carried back three years, but only against Section 1256 gains in those prior years. This allows you to recover previously paid taxes on earlier trading profits.

How it works: In 2026, if you have a net Section 1256 loss of $50,000, you may elect to carry it back to 2023 (three years back), then 2024, then 2025. The carryback applies only to Section 1256 gains in those years — you can't use a futures loss to offset stock gains or wage income from prior years. If prior-year Section 1256 gains were taxed at the 60/40 rate, the carryback generates a refund at that blended rate. Compare with the standard net operating loss carryforward rules, which do not allow carryback for most taxpayers.

The election is made on Form 6781 filed with the return for the loss year. If the loss exceeds prior-year Section 1256 gains, the excess carries forward 20 years.

How It Affects You

If you trade SPX, NDX, or VIX options: These cash-settled index options are Section 1256 contracts. Your gains automatically get 60/40 treatment regardless of holding period — even a same-day 0DTE trade that expires in two hours gets the blended rate. At top 2026 rates (37% ordinary, 23.8% LTCG + NIIT), your effective blended rate on Section 1256 gains is approximately 30.6% (60% × 23.8% + 40% × 37%) — versus 37%+ on short-term stock option gains. On $100,000 of profits, that's roughly $6,000-$10,000 less in taxes from the same trading activity. Your broker's 1099-B reports Section 1256 activity; use Form 6781 to report it separately from Schedule D. Your tax software should automate this, but verify — misclassifying SPX trades as regular options costs you the 60/40 benefit permanently for that year.

If you trade ETF options (SPY, QQQ, IWM): Options on SPY (S&P 500 ETF), QQQ (Nasdaq-100 ETF), and IWM (Russell 2000 ETF) are NOT Section 1256 contracts, even though they track the same indexes as SPX, NDX, and RUT options that do qualify. ETF options are equity options — all gains held under a year are short-term ordinary income. A trader making $100,000 in SPY options at a 37% rate owes $37,000; the same $100,000 in SPX options (same index exposure, cash-settled) owes approximately $26,800-$30,600 depending on long-term rate. If you're trading index exposure for tax efficiency, using cash-settled index options (SPX, XSP for smaller sizing, NDX, MNX, RUT, VIX) instead of their ETF counterparts can permanently improve after-tax returns without changing your market thesis at all.

If you trade commodity futures: CME-listed futures — corn, crude oil, natural gas, gold, silver, soybeans, coffee, live cattle — are all Section 1256 contracts. So are financial futures: S&P 500 futures (ES, MES micro), Nasdaq-100 futures (NQ, MNQ), Treasury bond futures, and bitcoin futures (BTC) on the CME. Your broker's 1099-B should flag these as regulated futures with Section 1256 treatment. Report them on Form 6781 — the IRS expects futures traders to use Form 6781, not Schedule D. The mark-to-market year-end rule means open positions on December 31 are treated as sold at that day's settlement price; your cost basis adjusts, so you only pay tax on gains from the December 31 mark when you later close the position.

If you had a large loss year in futures or index options: The three-year carryback election allows you to apply this year's net Section 1256 loss against Section 1256 gains in 2023, 2024, or 2025 — generating a refund at the 60/40 blended rate that applied in those prior years. The carryback applies only to prior Section 1256 gains, not wages, stock profits, or other income. Elect on Form 6781 filed with your loss-year return. To claim the refund, file amended returns (Form 1040-X) for each prior year with Section 1256 gains. If you had no prior Section 1256 gains, or if carrying forward is more valuable (because you expect higher rates in the future), skip the election and use the standard 20-year carryforward. Model both options with a CPA — the carryback generates cash today while the carryforward reduces future taxes at potentially different rates.

If you're managing straddles or offsetting positions: The § 1091 wash sale rules do not apply to Section 1256 contracts — you can close a losing futures or SPX position at year-end for the tax loss and re-enter the same position immediately without any disallowance. This is a meaningful advantage over stock and ETF trading. However, the straddle rules (§ 1092) do apply when you hold offsetting positions combining Section 1256 and non-Section 1256 instruments — for example, long S&P futures while short SPY puts on the same economic exposure. The straddle rules can defer or recharacterize Section 1256 losses in these combinations. If you systematically hedge futures positions with equity options, get tax advice on whether straddle rules are limiting your deductions.

State Variations

Most states with income taxes follow the federal 60/40 characterization and accept Form 6781 treatment. California conforms. New York conforms. The mark-to-market treatment is accepted across states. However, a few states tax all capital gains at ordinary income rates regardless of long-term/short-term classification, in which case the 60/40 federal advantage disappears at the state level — though the year-end mark-to-market rule still applies. Colorado, Montana, and several other states have capital gains preferences that interact with the 60/40 split differently.

Pending Legislation

No changes to Section 1256 are currently pending. The provision has remained largely unchanged since its enactment in the Economic Recovery Tax Act of 1981, which established the 60/40 rule and mark-to-market treatment for regulated futures. Proposals to harmonize futures and equity taxation have periodically been introduced but have not advanced. The cryptocurrency area creates some definitional questions — bitcoin futures (CME) clearly qualify; crypto spot trading on exchanges does not.

Recent Developments

The growth of retail trading in index options — particularly zero-days-to-expiration (0DTE) SPX options — has dramatically expanded the population of taxpayers using Section 1256. The IRS issued guidance in 2022 confirming that SPX options remain Section 1256 contracts. The increasing popularity of 0DTE options (which expire same-day) means many retail traders are in and out within hours — without Section 1256, these would all generate short-term gains; with it, every SPX trade gets 60/40 treatment regardless of the 10-minute holding period.

• OBBBA (2025) does not modify § 1256: the reconciliation bill focuses on extending TCJA income tax rates and business provisions without touching § 1256's 60/40 framework; the preferential treatment for futures and broad-based index options remains intact for 2025 tax planning purposes.
• Crypto derivatives and § 1256 classification: the IRS has not issued definitive guidance on whether Bitcoin futures contracts traded on regulated exchanges (CME) qualify as § 1256 contracts; many practitioners treat them as such, but the absence of a formal ruling creates audit risk; the Trump IRS's deregulatory posture makes new restrictive guidance unlikely in 2025.
• 0DTE options volume surged: zero-days-to-expiration SPX options now account for roughly 50% of daily SPX options volume; § 1256's 60/40 treatment is particularly valuable for active 0DTE traders since all gains are characterized as partially long-term regardless of the intraday holding period — a significant tax advantage worth modeling before scaling this strategy.
