How to Form an LLC in South Dakota

You can start an LLC in South Dakota on your own in five easy steps:

1. Name Your Company

You won’t be able to form your venture until you actually name it. Be sure to follow the LLC naming rules that are outlined in the South Dakota naming requirements.

Then, make sure the name you want isn't already taken by doing a South Dakota LLC name search on the State's website.

We also recommend using our LLC Name Generator tool to help secure a domain name for your new enterprise.

2. Choose a Registered Agent

You are required to designate a registered agent for your South Dakota LLC, which is an individual or business entity in charge of receiving legal documents, government correspondence, and more on behalf of your company.

If you form your company online on the South Dakota Secretary of State website, your registered agent’s name and contact information will be requested when you file your LLC’s Articles of Organization.

If you form your company by mail, download the Articles of Organization form, fill out the required fields, and submit a physical copy to the South Dakota Secretary of State. You’ll be asked to provide your registered agent under Article III.
