I registered my business as an LLC with the IRS and my state's attorney general office. When I printed out the paperwork I get sent, the federal government listed my business name with "LLP" at the end of it, not LLC. The state lists LLC with my business. Do I need to officially change this and if so, how would I do that? Or is this common, and it doesn't make a big difference? I am essentially a sole proprietorship but wanted to register as an LLC to avoid personal liability, as I am a life coach in private practice.
