In compliance with the IRS broker reporting requirements, IBKR will adjust the cost basis and holding period for disallowed losses on your tax forms. The Activity Statements, however, continue to display the actual purchase and re-purchase dates as the Cost Date. We do not enter the Holding Period Dates for wash sale adjusted lots on the default statements. As a result, a position opened during the "Short Term" holding period with a wash sale adjusted cost basis may actually display "Long Term" on the Activity Statements and Tax Optimizer. This difference is due to the IRS required "Holding Period" carry forward adjustment.
You can view the "Holding Period Date" for any wash sale adjusted open lot by creating a Flex Query:
- Log in to Client Portal.
- Click on Performance & Reports followed by Flex Queries under Reports.
- Click the Create "+" icon to create an Activity Flex Query.
- In Sections, select "Open Positions" and "Trades", and select "Holding Period Date Time (Wash sales)" and "Open Date Time" for positions.
See more details on how to Create an Activity Flex Query in the Client Portal Users' Guide.
