Before you register your South Dakota 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
• full list of South Dakota naming guidelines

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.

Once you register a domain name for your LLC, consider setting up a business phone system to establish credibility and enhance your customer service. Nextiva provides a plethora of useful features and a quick, easy setup. Try Nextiva.

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).

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

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.

Creating a South Dakota LLC operating agreement is the only way to legally lock down your LLC’s management and ownership structure. Having an operating agreement 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.

Pass-through taxation entails a business’s profits passing through to the LLC member’s individual tax returns. Like a sole proprietorship, an LLC is taxed as a pass-through entity, also known as a disregarded entity. 

Once this process is completed and after any tax-deductible expenses are taken out, the LLC members pay self-employment taxes and income tax on their portion of the business income. 

Alternatively, South Dakota LLCs can choose to elect to be taxed as an S corporation (S corp) or C corporation (C corp). If S corporation tax status is elected, LLC members can be taxed as employees of the business, potentially reducing tax burden.
