A limited liability company (abbreviated L.L.C. or LLC) is a legal form of business company that provides limited liability to its owners. it is a hybrid business entity having certain characteristics of both a corporation and a partnership. The primary characteristic an LLC shares with a corporation is limited liability, and the primary characteristic it shares with a partnership is the availability of pass-through income taxation. It is often more flexible than a corporation and it is well-suited for companies with a single owner.
The most affordable way to set up an LLc is to go to the state corporation section of the state forms and fill out yourself, cost is anywhere from $100 in TN to $300 in Tx, the forms are very easy and short.
