The Annual Statement (February 1) and the activity statements in Client Portal. Keep it with your return: with no form showing your trading profit, it's your record if the IRS asks.
- If the 1099-B reports your forecast contracts as Section 1256 contracts (boxes 8 to 11), the IRS expects them on Form 6781. You can file another way, but the IRS matches returns against 1099s, so expect to explain the difference.
- IBKR notes that its futures and Section 1256 1099-B can't be imported into TurboTax, so those figures are typed in by hand.
