A C-corp is like a big, official company club. When you form a C-corp for your business, it becomes a separate entity that can make money, own stuff, and pay taxes on its own. It's like giving your business its own identity, and the cool thing is that it can have lots of owners (shareholders) who own little pieces of it. But, just like a big club, it has to pay its own taxes, and sometimes you might have to pay taxes again when you take money out of the club. So, it's like a formal, big-business setup where you and other people can own parts of it and run it together.
