I'm dual citizen (US & Canada) residing in Canada. I returned to Canada two years ago. I just started thinking about investing again in Canadian equities (either stocks, ETF's or mutual funds). Then I found out about the tax reporting requirements of form 8621. From what I read online it seems that completing this form for each of your Canadian investments is too complicated and you'll end up spending more money having your taxes prepared than you can get from the investments. So my question is, if I buy US equities from my Canadian brokerage account do I still have to get the from 8621 completed or are these investments treated the same as my equity investments in my US brokerage account?
