I want to park some cash from a home sale (around 300k). Have been using SGOV for now and recently came across BOXX. With SGOV, I am paying federal tax currently (CA tax is exempt though). But I plan to move out of US in a year and wont have to pay capital gains or state tax at the point of sale. So BOXX seems definitely more advantageous here as basically will avoid any tax at all. Any risks that I am missing here? Is it safe to park that much cash in BOXX? TIA.
