<prompt> Human: Im a US citizen.SO is not a citizen.Can my SO give me money, then I open a new investment account with their money under my name?The idea being, they funnel me money, I invest it. Then years later, I give my SO that money or transfer it somehow.  <response>: Sure, you can accept as many gifts from someone as you want. Any tax liability or tax reporting for gifting is the responsibility of the giver. Your SO had better trust you quite a bit to do this, though, because you have absolutely no obligation to gift the money back in the future.
