A series LLC is a form of limited liability company that provides liability protection to multiple "series". Essentially, it's a master LLC with separate divisions, each protected and operating independently. As an entity, the series LLC is geared towards businesses where investors own multiple companies, with each series being protected from the debts and obligations of the other series. Currently, only several states support this option, including Delaware, Illinois, Iowa, Nevada, Oklahoma, Puerto Rico, Tennessee, Texas, and Utah.
PLLC, Professional Limited Liability Company: some states do not allow certain professionals to form an LLC that would limit the liability that results from the services professionals provide such as doctors, medical care; lawyers, legal advice; and accountants, accounting services; architects, architectural services; when the company formed offers the services of the professionals. Instead those states allow a PLLC or in the LLC statutes, the liability limitation only applies to the business side, such as creditors of the company, as opposed to the client/customer service side, the level of medical care, legal services, or accounting provided to clients. This is meant to maintain the higher ethical standards that these professionals have committed themselves to by becoming licensed in their profession and to prevent them from being immune (or at least limit their immunity) to malpractice suits.
With the proper planning, limited liability companies can exist for generations. S-Corps continue to exist even if the owners or majority shareholders leave or pass away. C-Corps continue to exist even if the owners or majority shareholders leave or pass away. Non-Profit organizations and institutions survive after their directors leave. Sole Proprietorships do not exist when the owner quits or passes away.
It should also be noted that the state of New York requires limited liability companies to comply with an unusually strict set of publication requirements. In addition to publishing notices in two papers in the county in which your business is forming, you will also be required to provide proof of this to New York’s Department of State within 120 days of becoming officially recognized as a business. Failing to do so can result in suspension of your right to conduct business in the state.
