 You can just declare a sole proprietorship. That's all you got to do. You don't need an LLC until you're making a million dollars or something. There's no point. The LLC doesn't do anything. You'll pay self-employment tax. That's it. If I were you, my side hustle right now would be to build a great handyman business so big that it forces you to quit your tiny little job, and then this whole thing has nothing to do with nothing.
