Determining SIPC coverage where multiple accounts exist

Multiple accounts maintained in the same name and taxpayer ID number are grouped for purposes of applying the maximum per client protection limits of $500,000 by SIPC and $29.5 million under Lloyd’s supplementary protection. However, if you hold accounts with IBKR in separate capacities (for example, an account in your name, a trust account of which you are the trustee or a beneficiary, or a joint account), then each account would be protected by SIPC and the supplementary protection up to the stated limits.
