Not quite everything, there's a (short) list of unsupported forms here: https://www.freetaxusa.com/forms-federal https://www.freetaxusa.com/forms-federal I found this out one year because they don't fully support Form 8283, which I needed in order to handle a deduction of a cryptocurrency donation to charity. But apart from that, they've been great. And your main point is correct in that they don't upcharge for any of their supported forms.
