Great info Lily, I didn't realize how easy it was to register as an LLC. I also did mine online on Connecticut's DRS website and it cost me a whooping $50
. I was consulting in my last job and my accountant recommended putting 25-30% way for tax purposes, it gets easier to put that much away when you begin.
Having a separate business account saves you a lot of time during tax season. All in all, taking these steps help with conditioning your mind as a business owner and not an employee and think about the impression you would make on potential clients.
