Step 1: Create A Name For Your South Dakota LLC

Before you register your LLC, you'll need to come up with a name. Your business name needs to be catchy for branding purposes and legitimate for legal purposes.

We go into depth on this topic in our LLC naming guide. We’ll go over the basics below.

Naming Your LLC

First, brainstorm some possibilities. Use our LLC name generator to get the ideas flowing.

Next, make sure your name meets South Dakota guidelines:

it contains the words limited liability company, limited company, LLC, or L.L.C.
it doesn't contain restricted words or phrases (these often include words like bank, attorney, and university) without approval
it's distinguishable from any other entity or trade name registered in South Dakota

Next, do a South Dakota LLC name search with the Secretary of State to find out if your name is available in South Dakota.

If your business name is available and meets guidelines, you’ll be able to register it when you file your Articles of Organization with the Secretary of State.

Is the URL available? Before you commit 100% to a name, check to see if there’s a good web domain available.

We recommend buying your domain right away because even if launching a business website isn’t on your radar right now, it will be soon.

Using a South Dakota DBA - Business Name (DBA)

A South Dakota DBA (doing business as), also known as a DBA - business name, is any registered name that a business operates under that isn't its legal business name. A DBA - business name can be used by any type of business, including a sole proprietorship, partnership, or limited liability company (LLC).

Learn how to get a DBA in our South Dakota DBA guide.

Step 2: Appoint a South Dakota Registered Agent

When you file your Articles of Organization, you'll need to list a registered agent.

A registered agent's job is to accept legal documents like service of process and tax notices for your LLC. To learn more about South Dakota Registered Agents, read our guide.

Your registered agent can be a person or a registered agent service. You can act as your own registered agent, but many business owners choose to use a registered agent service.

Here are a few things to think about before you decide to act as your own registered agent:

You’ll need to be available during normal (9 am - 5 pm) business hours at the address you provide
If you run your business from home, you’ll have to make your personal address public
You could be served with a lawsuit in front of your family or coworkers

Recommended: Northwest Registered Agent offers a free year of registered agent service when you form your LLC ($39 plus state fees).

Step 3: File the SD Articles Of Organization

It’s time to officially form your LLC by filing your Articles of Organization with the Michigan Department of Licensing and Regulatory Affairs.

You can file online with the South Dakota Secretary of State or fill out a hard copy of SD Articles of Organization and mail it in. The filing fee is $150 online or $165 by mail.

Recommended: Now is a good time to decide if your LLC will be member-managed vs manager-managed.

You'll need to know the following information to complete the form:

Entity Name
Business Purpose
Designated Office
Registered Agent Name and Registered Office Address
Organizers’ Names and Addresses
Duration
Governing Authority Type (LLC Management Structure)
Owner Liability

For more detailed help with completing the form, visit our South Dakota Articles of Organization guide.

Mail Your Articles of Organization:

Send the form and payment (payable to the Secretary of State) to:

Secretary of State Office
500 E Capitol Ave
Pierre, SD 57501

How long does it take to get an LLC approved? LLC processing is immediate after payment is received online, or 1 to 2 business days by mail.

Step 4: Create an LLC Operating Agreement

Creating a South Dakota LLC operating agreement is the only way to legally lock down your LLC’s management and ownership structure. Having this document in place will give you something to return to if a dispute or lawsuit arises.

Even single-member LLCs benefit from having an operating agreement.

Your operating agreement should outline the following:

Each member’s responsibilities
How new members will be admitted
How existing members may transfer or terminate their membership
How profits and dividends will be distributed

You can add as many provisions as you want, as long as they don't conflict with South Dakota business law. Take a look at our What is an Operating Agreement guide to learn more.

Step 5: Get an EIN

An Employer Identification Number (EIN) is like a Social Security number (SSN) for your company. The IRS and the state of South Dakota will use this number to track your business activity.

Your EIN will come in handy when it’s time to:

Open a business bank account
File Federal and State taxes
Hire employees

The best way to get an EIN for your LLC in South Dakota is by using the free online application on the IRS website.

Steps After Forming an LLC

After forming your LLC, it's important to:

Open a business bank account. A business bank account helps separate personal expenses and company expenses, which is required to maintain your LLC's corporate veil. A corporate veil protects your personal assets from creditors in potential lawsuits against your LLC or Business.

Learn more by reading this guide to Banking for Entrepreneurs. For a multi-member LLC, you'll also want to set up capital accounts for members. We also recommend checking out our review of the best business bank accounts.
Get a business credit card. A business credit card will help separate personal and business expenses while building your company’s credit history. A strong credit history will be useful for raising capital in the form of small business loans.
