With an LLC you can also pay taxes on a schedule attached to your 1040 so that you do not have to pay taxes as a company then pay individual taxes for what you pay yourself. Some states charge a flat fee if you do it that way. Here in CA if you claim LLC income on your federal 1040 and state tax form you pay a flat $800 franchise fee per year.
