IRS form used to report gains and losses from Section 1256 contracts including broad-based index options. Applies the 60/40 long-term/short-term split automatically.
⚡ KEY TAKEAWAY: If you trade SPX, NDX, or RUT options, your broker generates Form 6781 at tax time. The form handles the 60/40 split — you don't need to calculate it manually.
Why It Matters
Form 6781 is how you report Section 1256 contract gains/losses to the IRS. If you trade index options (SPX, NDX, RUT, VIX), this form gets you the 60/40 tax split.
How It Works
Your broker provides the data. You report the net gain or loss from Section 1256 contracts on Form 6781, which automatically applies the 60/40 split. The form also handles carryback of net Section 1256 losses to prior years.
Example
Your broker's 1099 shows $30,000 net gain on SPX options. Form 6781 splits it: $18,000 (60%) reported as long-term, $12,000 (40%) as short-term. You report both on Schedule D.
Common Mistakes
Forgetting to file Form 6781 when you trade index options. Your broker reports the total gain on the 1099, but you need Form 6781 to claim the 60/40 split. Without it, the IRS may tax the entire gain as short-term.
