Third party deposits are defined as those deposits which originate from or are drawn upon an account at a financial institution which is titled in a name other than that of the receiving account holder(s). Third party deposits also include deposits via check made payable to the account holder and endorsed over to IBKR; however, IBKR no longer accepts any check that is not made payable to IBKR.
As third-party transfers have historically been viewed by the financial services industry and its regulators as being highly susceptible to acts of fraud and money laundering, they are strongly discouraged and generally rejected by IBKR.
Checks payable to IBKR for the benefit of an account holder, for example an IRA rollover deposit, are not considered third party deposits. Account holders who are uncertain as to whether a particular check qualifies for acceptance should contact IBKR via ticket for clarification prior to remitting the check. Please select Funds & Banking as the ticket category followed by Cash Deposits and type "Check Deposit" as the subject.
