Section 1256 Contracts

A Section 1256 contract is a category defined in the US tax code that receives its own treatment, separate from ordinary stocks and options. The classification matters more than most traders realise, because it decides three things at once: how your gains are split between long-term and short-term, whether your open positions are taxed at year end even though you never closed them, and whether the wash sale rule can touch your losses. Two traders with identical profit and loss can owe meaningfully different amounts depending on which side of this line their instruments fall.

What the code counts as a Section 1256 contract

The definition is a list rather than a principle, which is why it catches people out. The main categories are:

• Regulated futures contracts traded on a qualified board or exchange. This covers the standard US futures most retail traders touch, including index, energy, metal and agricultural contracts, and their micro versions.
• Foreign currency contracts as the code defines them, which is narrower than "anything involving currency" and is a common source of confusion for retail forex traders.
• Non-equity options, meaning listed options whose underlying is not a single stock or a narrow-based index. Broad-based index options are the important case here.
• Dealer equity options and dealer securities futures contracts, which apply to registered dealers rather than retail traders.

Notice what the list does not include: options on individual stocks, and options on exchange traded funds. This is where most of the real-world confusion sits.

The SPX versus SPY trap

Two traders both say they "trade S&P options". One buys SPX options, the other buys SPY options. Economically the positions are close cousins. For tax purposes they are in different worlds.

A day trader who never holds anything overnight gets no long-term treatment at all on SPY options, because every position is short-term. The same trader in SPX options gets 60% of the gain treated as long-term even on a position held for eleven minutes. Over a year of active trading, that difference is not a rounding error.

Year-end mark to market, which is automatic here

Section 1256 contracts you still hold at year end are treated as if you sold them at fair market value on the last business day, and the resulting paper gain or loss goes on that year tax return. When the position eventually closes for real, the earlier mark is accounted for so the same money is not taxed twice.

This surprises people who are used to stocks, where an unrealised gain is invisible to the IRS until you sell. It also means a profitable open futures position can create a tax bill in a year when you took no cash off the table. Worth knowing before December rather than in April.

This automatic year-end mark is a feature of Section 1256 itself. It is a different thing from the mark-to-market election under Section 475(f), which is optional, applies to securities, and is only available to traders who qualify for trader tax status.

Why the classification is not something you choose

You do not opt into Section 1256. It follows the instrument. If you trade regulated futures, the treatment applies whether or not you knew about it, and whether or not your broker highlights it. That cuts both ways: the 60/40 benefit arrives automatically, and so does the year-end mark on open positions.

The practical consequence is that instrument selection is a tax decision as well as a trading one. Choosing between an index future, a broad-based index option and an ETF option changes your after-tax result even when the trade idea is identical.

What to keep in your records

Because Section 1256 results are reported separately from ordinary stock trades, your journal is more useful if it distinguishes them from the start rather than at filing time.

• The exact instrument, not just the underlying. "SPX Dec 5000 call" rather than "S&P call".
• Whether the instrument is a Section 1256 contract, recorded once per instrument type rather than per trade.
• Entry and exit dates, even though the holding period does not change the 60/40 split, because you still need them for everything else.
• Any positions still open at year end, which is what the automatic mark applies to.
• Broker year-end statements, which usually report aggregate Section 1256 profit or loss separately.
