A major concern is the limitation of liability, especially malpractice liability. Against the liability of your own malpractice, there is no entity that will protect you. For protection against liability for malpractice of co-owner professionals in the firm and possibly for other debts, Professional Limited Liability Companies (PLLCs), LLCs, and LLPs, when accessible for professional practices, should be used. Depending on the state law, Professionals Corporations (PCs) might not offer protection from liability for a co-owner’s malpractice.
LLPs, PLLCs, and LLCs all have about the same tax rules that govern them while those for PCs are a little more liberal.
