Additionally, adherence to specific naming guidelines is imperative, and a comprehensive understanding of these rules can be found on the South Dakota Business Names page.

Step 2: Provide an Official Business Address for Your LLC

Whether your business is situated in an office building, a residential setting for home-based operations, or any other physical location, every South Dakota LLC must have an assigned street address. While this address can be located outside of South Dakota, it's crucial to note that a P.O. Box is not an acceptable option by the state.

Step 3: Assign a Registered Agent

A Registered Agent is an individual who accepts official legal and tax communications and holds the responsibility of submitting reports to the South Dakota Secretary of State (SOS). Every South Dakota LLC is obligated to designate a Registered Agent.

This position can be filled by you, another manager in your business or a dedicated Registered Agent service. If your South Dakota Registered Agent is a person, they must have a physical street address in South Dakota and must be present during business hours to receive important documents on behalf of your business. In South Dakota, you appoint your Registered Agent when you file your Articles of Organization and formally create your business.

All of Bizee’s packages include Registered Agent service. It’s free for the first year and just $119 per year after that. We also provide you with access to our dashboard where you can easily view any document we've received on your behalf.

Step 4: File Your Articles of Organization with the South Dakota Secretary of State (SOS)

The articles must include:

  • Name of your LLC
  • Name and contact information of the Registered Agent
  • Name and address of each organizer
  • Principal address of the business
  • Whether the LLC is will be member-managed or manager-managed

Step 5: Get an Employer Identification Number (EIN) from the Internal Revenue Service

An Employer Identification Number (EIN) is essential for IRS identification of your business. This number is used during tax filing, payroll submissions, and employee payments. Additionally, it's required to establish a business bank account. You can acquire an EIN directly from the IRS, or Bizee can assist in obtaining one as part of the South Dakota LLC formation procedure.

Step 6: Create an Operating Agreement

Consider an operating agreement as a valuable "manual" that elucidates your business's operational structure. Within an LLC Operating Agreement, crucial elements are mapped out, including the methodology for decision-making, the distribution of member ownership, and protocols for member departures from the company.

Although some states require businesses to have this document in place, you're not legally required to have an LLC Operating Agreement in place to conduct business in South Dakota. We do recommend having one for your business nonetheless.
