Can I have more than two individuals on a joint account?

IBKR offers three types of joint accounts: Tenants with Rights of Survivorship, Tenancy in Common and Community Property. Each of these joint account types is limited to two account holders.

Applicants interested in opening an account with multiple owners in excess of two may consider the corporate, partnership, limited liability company or unincorporated legal structure account types offered by IBKR. Note that documentation establishing proof of formation and address are generally required at the point of application.
