For all clients, IBKR provides an Annual Statement and a Dividend Report. 

Your Annual Statement shows trade detail for your account gain and loss on a First In, First Out (FIFO) and a Mark-to-Market (MTM) matching basis or the specific method of tax accounting selected for your account.  Your Dividend Report shows account detail for all dividends, and payments in lieu of dividends, as well as withholding on these amounts.

US clients are also provided with a Gain/Loss Summary Worksheet and a Gain/Loss Worksheet for 1256 Contracts.  See the relevant FAQ for a description of the Gain/Loss Summary Worksheet.

The Gain/Loss Worksheet for 1256 Contracts shows detail on mark-to-market profit and loss for sales of equity options, futures (excluding single stock futures) and future options in your account.

For further explanations of these statements on the IB website, from the PRODUCTS menu select Tax Information and Reporting, and see the US Persons and Entities tab.  Your statements are accessible from our website by logging in to Client Portal and accessing the Tax section of the Reports menu.
