What documents do I need to file to form a limited liability company in South Dakota?
To form a limited liability company in South Dakota, an individual must typically file the Articles of Organization with the South Dakota Secretary of State. This document serves as the official registration of the limited liability company and includes important information such as the name of the company, the address of the principal office, the name and address of the registered agent, and the duration of the company if it is not perpetual.
It is essential for the name of the company to comply with South Dakota naming requirements, which include incorporating "Limited Liability Company," "LLC," or similar designations within the name.
In addition to the Articles of Organization, the individual forming the LLC may also want to create an operating agreement, although this document is not filed with the Secretary of State. The operating agreement outlines the management structure, rights, and responsibilities of the members, and the distribution of profits and losses.
Once the Articles of Organization are submitted, accompanied by the appropriate filing fee, the Secretary of State will review the application. If everything is in order, the limited liability company will be officially recognized.
For the most current procedures, fees, and additional requirements, it is advisable to refer to the South Dakota Secretary of State’s official website, which provides comprehensive information and resources for prospective LLC owners.
