Entity Name

Having a creative and smart business name is important but not as important as having a legally correct name.

When you choose a name for your business, you have to make sure the name:

  • meets South Dakota naming guidelines. 
  • is not already in use by another business in South Dakota. 

Follow the South Dakota Naming Guidelines:

  • Your name must include the phrase “limited liability company” or “limited company” or one of their abbreviations (LLC, L.L.C., LC, or L.C.). “Limited” may be abbreviated as “Ltd.” and “company” may be abbreviated as “Co.”
  • Your name cannot include words that could confuse your LLC with a government agency (FBI, Treasury, State Department, etc.).
  • In some states, certain restricted words (e.g., Bank, Attorney, University) may require additional paperwork and a licensed individual to be part of your LLC.
  • Your name must be distinguishable from any existing business in the state. This includes South Dakota reserved names.

Check Name Availability:

Is your name available in South Dakota? Make sure the name you want isn't already taken by doing a name search on the South Dakota Secretary of State website.

Register Your Domain Name:

We recommend checking to see if your business name is available as a web domain. Even if you don't plan to make a business website today, you may want to buy the URL in order to prevent others from acquiring it.

Business Purpose

In South Dakota, it is optional for an LLC to state its business purpose on its Articles of Organization.

Keep in mind that a business purpose that involves licensing, tax-exemption, or tax-deductible status requires specific language from the IRS or a professional license.

Designated Office Address

You must include the address of the LLC’s designated office where it conducts business.

Registered Agent and Registered Office

A registered agent accepts and sends legal documents on your LLC's behalf. When you register your South Dakota LLC, you are required to list your registered agent and your registered office.

Your registered agent can be anyone 18 years or older that lives in South Dakota. Your registered agent must always be available at the registered office during regular business hours. Your registered office address cannot be a P.O. box alone.

To learn more about choosing a South Dakota registered agent, read our How to Choose a South Dakota Registered Agent guide.

To learn more about what a registered agent does and how to choose one, read our What is a Registered Agent guide.


You must list the names and addresses of all the organizers of the LLC. They also all must sign the Articles of Organization.

LLC Duration

If your LLC’s duration isn’t perpetual, meaning it has a planned dissolution date, you must list that dissolution date here.

Governing Authority

When filing the Articles of Organization you will need to decide if your LLC will be member-managed or manager-managed. Before you file, read our Management by Members or Managers article to determine the best structure for your LLC.

Member Liability

If any members of the LLC will be liable for any of the company’s debts or obligations, list those here.

Steps After Your South Dakota LLC Is Officially Formed

Once you’ve filed your Articles of Organization, you should take the following steps:

Create an Operating Agreement

A South Dakota LLC operating agreement is a legal document that outlines the ownership structure and member roles of your LLC.

In South Dakota, you aren't required to have an Operating Agreement to officially form an LLC, but it's still a good idea to have one. You can start your operating agreement before, during, or after you file your Articles of Organization.

Your operating agreement will be kept in your LLC's private business records; you do not file it with the state.

Use our free Operating Agreement Tool to draft a customized operating agreement for your LLC.

Get an EIN

An Employer Identification Number (EIN) is like a social security number for your LLC. You will need an EIN if you want to hire employees or open business bank accounts.

You can get your EIN for free through the IRS website, via fax, or by mail. If you would like to learn more about EINs and how they can benefit your LLC, read our What is an EIN article.

Open a Business Bank Account

Using dedicated business banking and credit accounts is essential to protect your business' corporate veil. When your personal and business accounts are mixed, your personal assets (your home, car, and other valuables) are at risk in the event your LLC is sued.

Get Licenses and Permits

When you are registering an LLC, you need to determine if your business needs any licenses or permits to remain compliant. On the federal level, there are a handful of business activities that require licenses or permits.
