This person has a joint account in Interactive Brokers with his wife. The couple are not U.S citizens. Suppose the husband passes away suddenly without warning. Is the joint account subjected to U.S estate tax?

1 Answer 1


If the brokerage account holds US assets, such as the stock of US companies, then it may be taxable under some conditions. The rules are complex and depend on the nationality of the individuals, because the results may be affected by tax treaties between the United States and whatever country the person is from.

  • So, holding a joint account is useless in this event?

  • @curious The taxable portion would only be the portion probated to the deceased. So, the benefit of a joint account is potentially that only half the account would be subject to estate tax versus the whole account if it was solely owned. Feb 20, 2017 at 3:30
