We've laid out all the steps you'll need to take to form a legally recognized LLC in South Dakota, in chronological order.

An LLC is a type of business that helps protect its owners (called members). This means that if the business owes money or gets sued, the members’ personal assets, like their house or car, are usually safe. 

In the state of South Dakota, an LLC is defined as “an entity formed under [Chapter 34A]” (47-34A-101(9)). That means an LLC in South Dakota is a company created within the state or a company that becomes subject to South Dakota’s state regulations surrounding LLCs (Title 47 Chapter 34A).

If that sounds like a lot of legal jargon – that’s because it is! What you need to know is that LLCs are popular with business owners because they are simple and flexible to run. They have fewer rules compared to comportations and the owners can choose if they want to manage the business themselves or appoint managers to do it. 

Another benefit is how taxes work: LLC owners can pay taxes through their own personal tax returns, or they can choose to have the business pay taxes separately, like a corporation. This gives owners more choices in how they handle taxes as their business grows.

Why should I register for an LLC in South Dakota?

You may want to register for an LLC in South Dakota when:

  • You own or want to start a business in South Dakota, or want to expand an existing business into South Dakota, and want to stay legally compliant. 
  • You own or want to start a business, and want more flexibility on how you will manage the business or pay taxes than a corporation would provide.
  • You want to protect your personal assets from potential liability resulting from business you conduct in the state of South Dakota. 
  • You own or want to start a business, and want to register in South Dakota to open accounts, lease or buy property, secure funding, or hire employees.

Do I need to file my LLC in South Dakota if I live in another state?

Any LLC that does business in South Dakota must register with the State of South Dakota. LLCs based in South Dakota are called "domestic LLCs," and out-of-state LLCs are called "foreign LLCs." If your LLC was organized and operates outside of South Dakota, establishing a foreign LLC within South Dakota will allow for you to conduct business there.

Foreign LLCs and domestic LLCs may have different filing and compliance requirements -- Rocket Lawyer can help you navigate foreign LLC registration, regardless of where you live.

How to start an LLC in South Dakota

1. Find a unique name for your South Dakota LLC

The state of South Dakota says that the names of all LLCs in the state:

  • Must contain "limited liability company" or "limited company," or the abbreviation "L.L.C.," "LLC," "L.C.," or "LC." "Limited" may be abbreviated as "Ltd." and "company" may be abbreviated as "Co."
  • Are not too similar to existing LLCs in the state. You can search the state of South Dakota's database of business entities in the state to ensure your business' name is unique.

Rocket Lawyer can help you determine whether your business' name is eligible for registration in South Dakota and may be able to help you reserve the name before you file your LLC.

2. Include your other LLC members (if any)

In South Dakota, you can in fact form as a one-person LLC. In this case, the LLC would be referred to as a single-member LLC (SMLLC), whereas if there is more than one owner, the LLC may be called a multi-member LLC. 

The main difference between single-member and multi-member LLCs lies in ownership structure and management. With a single-member LLC, you have full control over the business. In contrast, a multi-member LLC has multiple owners, each with a specific percentage of ownership as defined in the operating agreement. This means that in a multi-member LLC, owners share profits, losses, and tax responsibilities based on their ownership percentage.

3. Provide a South Dakota address

This will be used as your official LLC address. The address that you list may either be your home, an office, or another physical location, but it cannot be a PO box.

4. Choose a Registered Agent

A Registered Agent is the person or business responsible for receiving tax, legal, and government documents during regular business hours. It's important that every business has one. You can either serve as your own registered agent (if you have a South Dakota address) or choose one to do that service for you (if you are not located in South Dakota or would like an extra layer of privacy).

5. Register your LLC with the state of South Dakota

Once you have a business name and registered agent, you can register your business as a South Dakota LLC with the state of South Dakota by filing your Articles of Organization. This document may be referred to informally as an LLC's "Articles," or in other states, it may be called a "Certificate of Organization," "Certificate of Filing," or "Certificate of Formation."

6. Get an Employer Identification Number (EIN)

South Dakota LLCs are required to have a Federal EIN tax number. Think of your tax ID as the social security number for your company. It will be important for business contracts, tax filings, and all manner of documents down the line. Every company should have one to remain in good standing.

7. Pay the state filing fee

Every state has different fees for forming an LLC, which can also vary from one year to another.

Congratulations! After you have completed all these steps, you have formed your South Dakota LLC.

What to do after forming a South Dakota LLC

There are a few steps you need to take to maintain your South Dakota LLC:

  1. Create an Operating Agreement: we can help you create your South Dakota LLC Operating Agreement online.
  2. Hold a meeting: a first meeting with members of an LLC is not required by law, but it is highly suggested in order to get organized. Also, unlike corporations, LLCs are also not required to maintain Meeting Minutes, but these documents are also recommended as they provide records for important decisions made.
  3. Pay taxes according to how you chose to be taxed: traditionally, LLCs are "pass-through entities." This means that you pay your business taxes on your personal tax form. That said, you can elect to be taxed like a corporation, if you choose to do so.
  4. File an Annual Report: this is required of all LLCs in the state and it is due on the first day of the LLC's organization anniversary month.

What is needed to keep records for my South Dakota LLC

South Dakota does not specify certain records that need to be kept. But it is advised to keep thorough records of your LLC because the state allows for members and managers of the LLC along with their agents and attorneys to access the LLC's records if a proper purpose is warranted. Documents kept for the LLC must be located at the company's principal office or a location stated in the Operating Agreement.
