Why the Futures 1099-B Looks Different
If you have traded stocks, you expect a 1099-B listing every sale with dates, proceeds, and cost basis. Futures are different. Section 1256 contracts are marked to market — settled daily and repriced at year-end — so the broker can summarize the whole year in an aggregate line instead of reporting thousands of individual trades.
The key figure is typically the aggregate profit or loss on Section 1256 contracts. That single number already reflects every mark-to-market adjustment through December 31, including positions still open at year-end. It flows to Form 6781, where the 60/40 split is applied.
What to Check Before You File
- Reconcile against your statements. The 1099-B should match the net of your monthly account statements. Small differences sometimes come from fees or interest handled separately.
- Watch for corrected forms. Brokers occasionally issue corrected 1099-Bs in February or March. Filing early off the first version can mean amending later.
- Confirm the account is yours alone. Joint, corporate, and IRA accounts report differently.
- Keep the backup. Retain monthly statements and your own trade log; they are your evidence if the IRS ever asks.
Common Questions and Edge Cases
Options on futures generally appear alongside the futures totals if they are Section 1256 contracts. Hedging accounts can look different, because identified hedges are usually ordinary income and may not run through the same aggregate line. And remember that the form reports trading results only — margin interest, data fees, and commissions may be handled elsewhere on the broker's year-end package.
If you trade more than one account — say a personal account and an LLC — expect a separate 1099-B for each, and resist the urge to net them together on one return line. Each entity reports its own way. Traders with both securities and futures at the same firm often receive a composite statement that lists the futures aggregate separately from the stock trade detail; make sure your preparer sees both parts.
