How to Start an LLC in South Dakota

An LLC (aka Limited Liability Company) is a hybrid business entity combining a corporation’s characteristics with a partnership or sole proprietorship. It separates your personal assets from your business assets, thus giving you personal asset protection. For an LLC, members’ personal assets are not affected by business debts. However, in some cases, if the LLC is sued for business debts, courts might pierce the corporate veil and use the owner’s personal assets to meet their corporate liabilities.

If you wish to start an LLC in South Dakota, you must file your Articles of Organization with the State and pay a filing fee of $150. While it’s the most important step, it’s not the only one. There are 4 other crucial steps to follow to get your LLC formed in South Dakota. Below are all 5 steps that explain everything you need to do to start a South Dakota LLC in 2024. Let’s get started! You can always hire a professional LLC formation service in South Dakota to set up your LLC instead of doing it alone; a Pro service will ensure everything is done properly.

Step 1: Decide a Name for Your South Dakota LLC

South Dakota name your llc

The first step while forming a limited liability company in South Dakota is to give a proper name to your LLC. Before you name your business, you must know that the name should be easy to remember, available in the state, and follows all the LLC naming guidelines.

South Dakota LLC Naming Guidelines

There are a few specific requirements all the LLCs in South Dakota must follow while naming their Company. Some of the most important requirements are as follows:

  • Your business name should be available and no other existing business in South Dakota can have the same name. ZenBusiness offers unlimited business name searches without any hassle.
  • “Limited Liability Company”, “LLC”, and “L.L.C.” – any one of these has to be used as a suffix in your business name.
  • You cannot use any name for your business that is confusing or misleading. Terms such as “Treasury”, “State Department”, “FBI”, “CIA”, etc. shouldn’t be included.
  • Terms like “Bank“, “University“, “Attorney“, “Doctor“, etc can be added only after the additional requirements by South Dakota State Government are fulfilled.
  • (Optional) It’s better to name your business something for which your desired domain is available.

Reserve Business Name for Future

If you do not wish to file your LLC right now but want to hold the name you have decided on, then you can reserve your LLC name for 120 days. To keep the name, you must file a name reservation application and pay $25 to reserve your name with the South Dakota Secretary of State.

Doing Business As (DBA) or Trade Name

Once you have a legal name for your LLC, you can register it. However, it is not mandatory. You can, instead, use DBA, Fictitious Name, or Trade Name. In that case, you must register your name with the South Dakota Secretary of State by submitting an Application to Register a Trade Name in South Dakota along with the filing fee of $10.

Recommended: You can do name search, business domain, website, emails, and a lot more in one place by hiring a professional service. We recommend using –


ZenBusiness($0 for LLC Formation)

Apart from LLC formation, ZenBusiness offers customized website templates and business emails at a very reasonable price. If you plan to get a website, then it is wise to have a “.com” domain for your business, but these days you can also use other TLDs like “.io”, “.company”, “.xyz,” etc. Here you can get everything you need for your business in one dashboard.

Do I have to include LLC in my company email/domain?

It is not legally mandatory to use the word LLC in your domain name or email. If you want, you can use it. However, it is recommended not to use LLC in the domain name. A domain name should be short and easy to remember.

Step 2: Assign a Registered Agent in South Dakota

South Dakota registered agent

The second step to forming an LLC in South Dakota is to appoint a Registered Agent. A registered agent is a person or business entity working on your LLC’s behalf. This person or business will receive important tax forms, legal documents, all notices of lawsuits, and other official government correspondence in South Dakota. Hence, hiring a competent South Dakota Registered Agent for your LLC is necessary.

Make sure your registered agent is a resident of South Dakota or has a physical street address. This address will be used as the principal address of your LLC to receive any legal documents. Most LLC formation companies also provide registered agent services. Below are two great LLC formation services; even if you buy their cheapest plan (normally $0), you also get registered agent service and other services at a very reasonable price.

This standalone service might become handy if you are doing it yourself and don’t want to disclose your home address or you don’t want to pierce the corporate veil.

Who Can Be a Registered Agent?

A person above 18 years of age and has a physical address in the state of South Dakota can be a Registered Agent. A Registered Agent can be an independent person or can be a business entity. One is responsible for handling all the legal documents on the LLCs behalf.

Can I Be My Own Registered Agent?

Yes, you can be your own registered agent if you are a resident of the state of South Dakota and you are above 18 years of age. To become a registered agent, you must have the authority to conduct any type of business in South Dakota.

Why Shouldn’t I be My Own Registered Agent?

There are a few reasons why you shouldn’t be your own registered agent. The address of the registered agent is used to communicate with the SOS or for any legal activities. If you are your own registered agent, you might have to upload your personal address to the public forum. Besides, the registered agent must be at the address during business hours. It won’t be easy for you as you also have to take care of other things in your LLC. Hence, it is wiser to appoint a separate entity as your registered agent.

What is Piercing the Corporate Veil in LLC?

If an LLC is sued in South Dakota, in some cases, courts might decide to lift the corporate veil, which means the owners of the LLC will be personally liable for their business debts. They might have to forgo their personal assets to repay their business debts. This is called piercing the corporate veil, where personal and business assets are not separated anymore. Your personal assets can be protected if you have enough capital and all your LLC documents are properly filed.

Registered Agent Consent Application

In South Dakota, there is no separate Consent Letter to be produced to the Secretary of State. At the time of change of Registered Agent (or the name or address), the new Registered Agent has to sign the consent letter. It comes with the Application form to Change the Registered Agent. The filing fee of $10 should be paid for it. For more information on the same, read our guide on South Dakota Registered Agent.

Step 3: File Articles of Organization in South Dakota

The Articles of Organization include details like the name of the LLC, the registered agent’s name, address, employees’ details, and the company’s structure (member-managed or manager-managed).

Moving on to the fourth step, filing your operating agreement. An operating agreement is a document that legally outlines the proprietorship and operating procedures of your LLC.

This document is vital as it ensures that all business owners are on the same page regarding how they operate, thus reducing future conflicts.

When it comes to filing a South Dakota LLC Operating Agreement, the state does not require you to have a comprehensive operating agreement, but it is ideal to have one that contains all the details of your business operation that helps in taking future business decisions, especially if you decide to dissolve South Dakota LLC later.

After Starting Your South Dakota LLC

After forming your LLC, there are still some things that you will need. The most important thing is to separate your business and personal assets. LLCs have limited liability protection that protects your personal assets from business liability. This is called a corporate veil. However, the corporate veil can be lifted or pierced by the court if the LLC is sued. In that case, the owners of the LLC become personally liable for their corporate debts. A few things like appointing a legit registered agent, having enough capital, and filing all the major documents with the state can save the LLCs from being pierced into the corporate veil.

BOI Report Filing

According to the Corporate Transparency Act, every LLC, corporation, and other type of business that is registered with the South Dakota SOS or similar authority, must file the BOI report with FinCEN. From January 1, 2024, it is mandatory to file a BOI report for every business entity. In this report, LLCs have to share information about the beneficial owners (having equal or more than 25% share). LLC owners can file BOI reports online or offline.

LLCs in South Dakota that are created before January 1, 2024, should file their BOI report by January 1, 2025. LLCs that are created in 2024, must file the BOI report within 90 business days of finishing the LLC formation process. Missing out on filing the BOI report may lead to a monetary penalty of $500/day.
