Solo 401k Brokerage Account with Interactive Brokers

QUESTION: I do have a brokerage acct with Interactive Brokers for my personal account. Can I use them to open a brokerage account for my solo 401k?

Thank you,

Terry in Maryland

ANSWER: Yes you can open a brokerage account for your solo 401k through Interactive Brokers. The following link will take you to the Interactive Brokers on-line trust application.

You will want to click on “Protrack Application” to fill-out the on-line “Trust Application”.

However, you will not be able to invest the self-directed solo 401k through the Interactive Brokers brokerage account in alternative investments such as real estate, notes, trust deeds, tax liens or private companies, for example.  Instead, you will need to open a separate bank account for the solo 401k if you want to process alternative investments by writing a check or by wire, or if you want to process a solo 401k loan. If you want to be able to do everything under one umbrella—that is, invest in equities, alternative investments such as real estate as well as process solo 401k loans, the Fidelity solo 401k brokerage account may be a better option.


Add Margin Trading  QUESTION:


Can I add margin trading to my Interactive Brokers solo 401k?


While the solo 401k plan already allows for investing via margin, a factor to consider is whether investing in margin will subject your investment to Unrelated Business Income Tax. CLICK HERE & HERE for more information on Margin and UBIT.  
Practically, speaking this change would be done via the brokerage. I understand that you already have a brokerage account(s) at Interactive Brokers.
