What Is Form 6781: Gains and Losses From Section 1256 Contracts and Straddles?
Let me explain Form 6781 directly: it's the IRS form you use to report gains and losses from straddles or financial contracts classified as Section 1256 contracts. If you're trading these, you'll need it for your taxes.
A straddle means holding contracts that offset each other's risk of loss. For instance, if you buy a call option and a put option on the same security at the same time, that's a straddle.
Most options and futures traders file this form annually. For these investments, you report 40% of the gain or loss as short-term and 60% as long-term.
Key Takeaways
Form 6781 comes from the IRS and helps investors report gains and losses from straddles or financial contracts. It has distinct sections for straddles and Section 1256 contracts.
Section 1256 contracts cover regulated futures contracts, foreign currency contracts, options, dealer equity options, or dealer securities futures contracts.
Who Can File Form 6781: Gains and Losses From Section 1256 Contracts and Straddles?
If you're an individual tax filer, you must report gains and losses for these contracts under mark-to-market rules. The form separates sections for straddles and Section 1256 contracts, so identify your investment type accurately.
Section 1256 contracts are treated as sold at year-end, even if not closed, and valued at fair market price to calculate gains and losses.
Take this example: suppose you bought a regulated futures contract on May 5, 2024, for $25,000, and it's worth $29,000 at year-end. That's a $4,000 mark-to-market profit, reported as 60% long-term and 40% short-term on Form 6781.
Then, if you sell it on Jan. 30, 2025, for $28,000, you record a $1,000 loss on your 2025 return, again split 60/40.
You use Form 6781 for straddles and Section 1256 investments, but hedging is handled differently. Since these contracts are marked as sold yearly, all gains are 60% long-term and 40% short-term, no matter the holding period.
This setup lets you take 60% of profits at long-term rates even if held briefly.
Important Note
You must report gains or losses from foreign securities contracts on foreign exchanges using Form 6781, even if they wouldn't normally qualify as Section 1256 contracts.
How to File Form 6781: Gains and Losses From Section 1256 Contracts and Straddles
In Part I, report Section 1256 gains and losses at the sale price or Dec. 31 mark-to-market price.
Part II covers straddle losses in Section A and gains in Section B. Part III is for unrecognized gains at year-end, but only if you recognize a loss on a position.

What Is an Options Straddle?
An options straddle involves buying a call and put option with the same strike price and expiration on the same stock. It lets you profit from price swings in either direction, but if the price stays flat, you lose on the premiums paid. This works best with volatile prices.
What Does Mark-to-Market Mean?
Mark-to-market values assets or liabilities at current market price, not original cost, to reflect real-time values in financial statements. It can cause fluctuations with volatile assets.
Why Are Long-Term Capital Gains Better?
Long-term capital gains are taxed at lower rates—0%, 15%, or 20% based on your bracket—compared to short-term gains taxed as ordinary income up to 37%. You keep more profits this way.
The Bottom Line
If you're trading Section 1256 contracts or straddles, Form 6781 is required to report gains and losses correctly for taxes. These include futures, options, and some foreign contracts, marked to market at year-end.
This allows a 60% long-term and 40% short-term split, potentially saving on taxes. The form ensures you comply with IRS rules on your investment activity.
