Are you looking for another entity type? We offer several other guides for the state of South Dakota.

One of the first decisions you'll need to make as a new business owner is which type of entity you will form for your business. While each business type offers its own benefits, forming an LLC (limited liability company) is one of the most popular choices made by new business owners across the United States. An LLC is a relatively new type of legal business formation, considered a hybrid entity, combining the pass-through taxation and simple operation of sole proprietorship with the limited liability protection provided by a corporation.

One of the main reasons for the growing popularity of the LLC in South Dakota is its simple setup and flexible structure. An LLC is also considered the easiest type of entity to maintain with the least number of annual requirements. Plus, income from the business is passed directly to its owners as regular income, making taxes much easier for an LLC, which can help you lowering your tax preparation costs each year.

The Benefits of an LLC

  • Protect your Personal Assets
    Starting a business designates your business as a separate legal entity, preventing you from being personally responsible for the debts of your business.
  • Build Credibility
    Establishing a professional identity provides the benefit of showing potential customers and investors that your business is legitimate and here to stay.
  • Simple Management
    Limited liability companies are less formal and require fewer annual / maintenance requirements than other common entity types, making it a popular choice for small business owners.

Compare the main entity types below

Entity Type

Limited Liability Company Combines limited liability protection with a pass-through tax structure. IRS rules allow LLCs to choose between being taxed as partnership or corporation. The easiest entity to maintain with the least amount of formal annual requirements.

Non-Profit Corporation A corporation formed for a charitable, educational, religious, literary, or scientic purpose. Contributions to charitable corporation are tax-deductible. Can get tax exempt status with the IRS. Annual reports, minutes, meetings are required to maintain nonprofit / tax exempt status.

The next step will be to decide on a name for your business. Choose a name that is memorable and unique, easy to understand and pronounce, and accurately represents your business. You'll want to search your name choices on the web to quickly find out if they are already taken. It's also best to jot down one or two alternatives, in case the name you settle on is not available for registration in South Dakota.

There are a few rules that South Dakota Limited Liability Companies must follow in order to register a name.

  • The name you choose must be unique and not "confusingly similar" to the name of any other South Dakota business. This is to prevent fraud or misrepresentation and is a common rule in all 50 states. You can find out whether a name is available by conducting a business entity name search through the South Dakota business name availabilty tool for possible conflicts. Be sure to check variations or alternate spellings as well, otherwise your filing may be rejected. In a pinch, you can use MyCorporation's business name search service, where we will conduct a more thorough search on your behalf and report back our findings.
  • For a South Dakota LLC, you must include one of the following endings: "limited liability company," "limited company," or abbreviations like "LLC" or "L.L.C.," "L.C.," or "LC."

You can learn more about how to choose and register a business name and other important statutory information through the South Dakota Secretary of State.

Tip: A business name check is included with every one of our business formation packages. We check with the state to determine the availability of your business name automatically. You can also conduct a nationwide business name search here.

There are two options to choose from when it comes to setting up your limited liability company in South Dakota. "Member managed" or "manager managed". The first thing you need to know is that owners of any LLC are referred to as "members". A single member LLC has just one owner, while a multi-member LLC is an LLC owned by 2 or more members. Pretty simple, right?

South Dakota LLCs also must also designate one or more individuals to manage the day to day operations of the business. This can be handled by one of the members of the business (member managed, the most popular choice and the default in most states), or a professional manager appointed by the members to act on their behalf (manager managed).

While the differences are subtle, what you really need to know is that each member in a member managed LLC has the power to make decisions for the business. However, in a manager managed LLC, the members choose who will manage the business and relinquish all of the decision making to the manager chosen. The person chosen can be one of the members of the business as well, or it can be someone else entirely.

Most states require that you designate a registered agent for your business, and South Dakota is no exception. A registered agent acts as the state's means to communicate with a business and is responsible for receiving legal and official documents related to the business.

A registered agent can be anyone you wish, with one small caveat. The registered agent must have a physical address in South Dakota. In other words, a P.O. Box is not allowed as a registered agent address. This means a member of the limited liability company can act as the registered agent if desired, or a third-party registered agent service like MyCorporation can be used.

Why designate a third party to act as my registered agent?

It should be noted that registered agent information is made publicly available. This can cause privacy concerns for business owners who do not wish to list their personal contact information on the internet for everyone to see. It is also common for the registered agent to become a target of spam or robocalls since this private information is relatively easy to obtain. Another issue that may arise is that in the case of a lawsuit, these documents would be hand delivered directly to the registered agent, and in the case that you used your business location for this purpose, this could occur in front of your customers. This is why many business owners opt for a third-party registered agent service such as MyCorporation to act as a registered agent on behalf of their business.

The state of South Dakota requires you to file Articles of Organization to form an LLC. This document includes basic information about the South Dakota LLC such as:

  • Name of the limited liability company (must include one of the following endings: "limited liability company," "limited company," or abbreviations "LLC" or "L.L.C.," "L.C.," or "LC."
  • The purpose/purposes for which the LLC is to be organized (optional)
  • Address of the initial designated office of the LLC
  • South Dakota registered agent's name and street address
  • Name and address of each organizer
  • The duration of the company
  • Whether the company will be member managed or manager managed (check off a specific box)
  • If one or more members of the company are liable for its debts and obligations
  • Other provisions
  • Name and signature of each organizer and date

A filing fee of $165 is required when submitting the Articles of Organization. If you file by paper, you must also include a $15 paper filing fee. Make the check payable to the Secretary of State.

After formation, the state of South Dakota requires an LLC to create an operating agreement. This agreement needs to be written, and should be kept with the company's records. In order to open a bank account for your business, you will often be required to submit both your operating agreement, and your EIN number.

What kind of information needs to be included in a South Dakota operating agreement?

Operating agreements are required in South Dakota and are important to laying the foundation of a properly run business. An operating agreement sets guidelines for the way your business operates now and into the future. Common details in an operating agreement include the following:

  • Basic contact details: The name of the LLC, the address of the principal business location and often, the registered agent address.
  • The business purpose: This is a basic one sentence description of what kind of business your LLC will do, and is often a very general description, which creates a bit more flexibility as the business matures.
  • Tax structure: Often this indicates the way the LLC will choose to be taxed. The main options are to be taxed as a sole proprietor or a partnership ( both pass through options ) or to be taxed as a corporation ( which requires an S Corp Election to be filed )
  • Ownership and management: This section lays out the general rules about how the business will operate day to day. This refers to step 3, where you determined whether your business would be "manager managed" or "member managed". As mentioned before, member managed is the default and the most common choice. If you are unsure, member managed is a pretty safe bet.
Tip: All of our formation packages include a sample operating agreement you can use directly, or modify to fit your needs. Start Now

Your South Dakota LLC may need to check in with the Secretary of State for more information about the licenses and/or permits required by your business. Several factors, including the company's industry and county location, may determine which documents need to be filed.

An EIN (also called a Federal Tax Id) is a nine-digit number that is issued by the IRS and used to uniquely identify your business for tax purposes. Think of it as a Social Security Number (SSN) for your business, except an EIN is far less sensitive. It is important to wait until the LLC has been approved by the state before applying, and for that reason, filing for an EIN is one of the last things to do when you are setting up a business.

Like a social security number, the EIN allows you to:

  • Open business checking, savings, or investment accounts
  • File taxes for the business
  • Complete payroll for employees if applicable
  • Obtain lines of credit and credit cards, as well as "build credit" for your business
  • Apply for applicable business licenses when required.

You only need a few pieces of information to file including your mailing address and legal business name. You can apply online with the IRS by downloading IRS Form SS-4, or work alongside a third party organization like MyCorporation to complete an EIN application.

Frequently asked questions

In South Dakota, if your profession requires state licensing, you would incorporate your business as a Professional Service Limited Liability Company (PLLC). This often includes doctors, lawyers, therapists, and other professions where state licensure is required.

A PLLC is different than a Professional Corporation (PC), which consists of shareholders that own company stock and has different tax implications. South Dakota allows licensed professionals the opportunity to form both a PLLC and PC, if desired. PLLCs are usually more popular, as they require less effort to build and operate.

Generally, this can include the following professions:

  • Accounting
  • Acupuncture
  • Architecture
  • Chiropractic
  • Clinical social work
  • Dentistry
  • Law
  • Marriage, family, and child counseling
  • Medicine
  • Speech-language pathology and audiology
  • Nursing
  • Optometry
  • Osteopathy
  • Pharmacy
  • Physical therapy
  • Physician assistants
  • Podiatry
  • Psychology
  • Shorthand court reporters

If you choose to register an LLC by mail, it takes 3-5 business days to start a South Dakota LLC. If you register online, it may take up to 1-2 business days.
