Look, I understand how people use the phrase "passive income", but it's really not correct. Like "object" or "unit test" "passive income" is a term with a meaning. It has advantages for you to understand the difference between "unit test" and "regression test". It also has advantages to understand the difference between "active income", "passive income", and "portfolio income". For once you can speak with professionals without misunderstandings, and you can think about a topic in a different way. When you understand what "passive income" means you will see, that you actually really like "passive income" from a tax paying point of view, even if you have to work as hard for it as you would for your "active income" (e.g., salary). The thing is, though, that often if you have to work hard for something that is considered "passive income", then you are probably doing something wrong or it's actually your "active income".
