A medical company of that size and revenue should exist as in incorporation vs an LLC. Some of the benefits of owning and incorporation over an LLC include the following. Corporation owners enjoy limited liability protection, and are usually not individually responsible for business debts. Also they often gain tax gains, such as writing off health insurance premiums. Even if an owner dies or sells interest, the corporation still exists. Corporation ownership can be easily transferable and capital can be raised more easily through the sale of stock. Another advantage is that many banks prefer handling loans with incorporated borrowers. Retirement funds and qualified plans, like a 401(k), can be easier to establish.
