How to Register Your Business in South Dakota in 7 Simple Steps

Setting up a business in South Dakota can be a streamlined process if you follow these 7 steps diligently. By adhering to these guidelines meticulously, you can expedite the registration of your South Dakota-based business and get it up and running swiftly.

Step 1: Choose Your Business Structure

The choice of business structure in South Dakota depends on the type of business you plan to start and your expansion goals. We have already discussed the different types of incorporated and unincorporated businesses available in South Dakota. Now, let’s examine each of these options and how they operate.

Please note that if you choose a structure that requires incorporation, such as those outlined below, you will need to register your business with the South Dakota Secretary of State.

Sole Proprietorship

A sole proprietorship is the simplest business structure in South Dakota, where the owner and the business are legally considered the same entity. This means that the owner is personally responsible for the business’s debts and liabilities. Setting up a sole proprietorship is easy and involves minimal legal and administrative requirements. In South Dakota, there is no need to register your sole proprietorship with the state, but you may have to obtain local permits or licenses.

General Partnership

A general partnership is a business owned by two or more individuals who share in the profits and losses. Each partner is personally liable for the business’s debts and legal obligations. In South Dakota, there is no requirement to register a general partnership with the state, but you may need to file a “South Dakota Assumed Business Name Certificate” (DBA) in the county where your business operates.

Limited Partnership (LP)

In South Dakota, a limited partnership consists of one or more general partners who manage the business and have unlimited personal liability, along with one or more limited partners who contribute capital but have limited liability. To create an LP in South Dakota, you must file a “Certificate of Limited Partnership” with the South Dakota Secretary of State.

Limited Liability Company (LLC)

An LLC is a flexible business structure that combines the liability protection of a corporation with the tax benefits and simplicity of a partnership. In South Dakota, you need to file an “Articles of Organization Limited Liability Company” with the South Dakota Secretary of State and create an Operating Agreement to outline the company’s management and ownership structure.


A corporation is a separate legal entity from its owners (shareholders) that offers limited liability protection. In South Dakota, there are two types of corporations:

  • C-corporations
  • S-corporations

To establish a corporation in South Dakota, you must file an “Articles of Incorporation For-Profit Corporation” or “Articles of Incorporation Nonprofit Corporation” with the South Dakota Secretary of State, depending on your business type. Corporations have more formalities, including creating bylaws, issuing stock, and holding regular board and shareholder meetings.

Choose the business structure in South Dakota that best fits your needs, considering liability protection, taxation, and management requirements. Consult with a legal or business professional if you need guidance in making this decision.

Step 2: Select a Unique Business Name

In South Dakota, there are various options for naming your business. You can register a legal entity name, secure a trademark, or register a legal name and operate under a different one. The specific regulations governing business naming vary from state to state, so it’s essential to familiarize yourself with the requirements for South Dakota.

Similar to the process of incorporating your business, the naming approach you choose in South Dakota will depend on the unique needs and circumstances of your entity.

While it may be prudent to pursue all three avenues to ensure the exclusivity of your chosen name, you can also opt for a single method. Although not mandatory, maintaining consistency across all registration methods by using the same name is generally recommended.

Let’s examine each of the naming options available in South Dakota more closely:

In South Dakota, businesses must register a legal entity name, which serves as the official identifier for the company as recognized by the state. To protect your name from potential duplication by other businesses, it must be distinctive.

South Dakota’s naming laws include guidelines concerning company suffixes (e.g., LLC, LP, or Corp) and require that the name accurately reflects the type of business being registered. You can verify name availability by utilizing the database provided by the South Dakota Secretary of State.


In South Dakota, a trademark provides intellectual property protection for a business name or logo at the national level. It’s crucial to conduct a comprehensive search in the USPTO database to ensure that the name or logo you wish to protect isn’t already registered.

Once registered, a trademark grants you exclusive rights to the name or logo, preventing others from using a similar name or logo for similar goods or services nationwide. However, it’s important to note that obtaining a trademark does not automatically confer universal usage rights for the name or logo in all circumstances.

Operating Under a Different Name (DBA)

In South Dakota, you have the option to register your business under an official name while operating under a different name, commonly referred to as a Doing Business As (DBA) name. To establish a DBA, you need to file an Assumed Business Name Certificate with the appropriate county clerk’s office in the county where your business is located. While federal trademark laws apply to these names, there is no requirement for a DBA to be unique at the state level.

By understanding and carefully considering these naming options, you can successfully register your business name in South Dakota while protecting your brand identity.

Step 3: Consider Taxes and Other Costs in South Dakota

South Dakota LLCs are subject to a variety of taxes, including:

  • Franchise Tax: The South Dakota franchise tax is a flat tax of $50. This tax is due on the anniversary of the LLC’s formation. The franchise tax is used to fund a variety of state programs, including education and transportation.
  • Sales Tax: South Dakota has a statewide sales tax of 4.5%. This tax is applied to most goods and services sold within the state. However, there are several exemptions, such as food and medicine.
  • Property Tax: South Dakota property taxes are assessed by local taxing authorities. The property tax rate is determined by the assessed value of the property. The assessed value is usually based on the purchase price of the property, but it can also be based on the fair market value.
  • Income Tax: South Dakota LLCs are not subject to income tax at the state level. However, LLC members may be subject to income tax on their share of the LLC’s profits. The income tax rate for individuals is progressive, ranging from 1% to 10%.

In addition to these taxes, South Dakota LLCs may also be subject to federal taxes. The specific taxes that an LLC is subject to will depend on the activities of the LLC and the tax status of its members. If you’re considering forming a South Dakota LLC, you should consult with a tax advisor to determine the specific taxes that your LLC will be subject to.

To facilitate the registration process, entrepreneurs in South Dakota can take advantage of online services, such as ZenBusiness. ZenBusiness offers a diverse range of solutions that assist business owners in registering their ventures, including activities like filing with the Secretary of State, obtaining an Employer Identification Number (EIN), and creating an operating agreement. Furthermore, they provide ongoing compliance support to ensure businesses remain in good standing with the state.

Step 4: Register and Acquire Licenses and Permits in South Dakota

To comply with legal requirements, it’s necessary to apply for licenses and permits when starting a business. The following registrations and authorizations are essential:

Tax Registration: If your business involves selling goods in South Dakota, it’s mandatory to register with the Department of Revenue (DOR) to collect sales tax. You can conveniently complete the registration process online through the DOR’s official South Dakota Tax Application website.

Employer Identification Number (EIN): If your business has employees or is taxed separately from your personal income, obtaining a federal Employer Identification Number (EIN) from the IRS is necessary. Even if not explicitly required, obtaining an EIN is often beneficial for business purposes. Banks typically require an EIN to open a business account, and other companies you engage with may require an EIN to process payments. Applying for an EIN can be done easily through an online application without any filing fees.

Regulatory Licenses and Permits: These licenses and permits are for various areas such as health and safety, environmental compliance, building and construction, as well as specific industries or services. The Governor’s Office of Economic Development (GOED) provides a downloadable document that outlines the licenses issued by numerous state agencies, including the Departments of Agriculture, Environment and Natural Resources, Health, and Labor & Regulation. To apply for important state business licenses related to taxes, you can complete the South Dakota Tax Application. 

Additionally, it’s advisable to check the websites of cities or counties where your business operates to inquire about any local licenses and permits that may be required.

Professional and Occupational Licenses: These licenses apply to individuals working in various professions or occupations. The South Dakota Department of Labor and Regulation website features the Occupational Licensing Agencies section, which lists multiple state agencies and boards responsible for regulating different professions and occupations. 

Likewise, the South Dakota Boards and Commissions Portal offers a searchable list of licensing agencies and boards. It’s recommended to consult these resources to identify and apply for specific professional or occupational licenses relevant to your business activities.

Step 5: Open a Bank Account For Your Business in South Dakota

Once you have obtained your EIN, it’s imperative to establish a business bank account in South Dakota

Compliance with the state’s laws regulating LLPs, LLCs, and corporations necessitates the opening of a business bank account. However, sole proprietors and unincorporated partnerships are not legally obligated to maintain separate personal and business bank accounts. 

Initiating the process involves visiting a local bank in South Dakota and completing the required paperwork. It’s advisable to conduct thorough research and compare the rates and perks offered by different banks before selecting a specific provider. 

Even if you currently operate as a sole proprietor or unincorporated partnership, having a designated business bank account in South Dakota is recommended to ensure clear financial separation. This foresighted measure will also alleviate potential complications should you opt to incorporate your business at a later stage.

Step 6: Protect Your Intellectual Property in South Dakota

In South Dakota, it’s essential to take steps to protect your valuable intellectual property (IP) when starting a business, depending on the type of company you have.

For instance, most businesses aim to safeguard their name and logo from being copied and used by other entities. Whether your business involves selling goods or offering services, you may also want to protect the design of your products or the creative works you produce, such as writing, designs, or music.

South Dakota offers various methods to achieve this, and it’s beneficial to initiate the necessary applications promptly to prevent unauthorized use of your IP.

File a Trademark with Bizee


In South Dakota, a trademark is a recognizable symbol, phrase, word, or design that distinguishes a product or service from similar offerings in the market.

To obtain legal protection, trademarks must be registered with the United States Patent and Trademark Office (USPTO). The registration process typically takes four to six months to complete. Once registered, the trademark is protected nationwide, enabling legal action against unauthorized use.

Businesses in South Dakota can protect their trademarks by registering them with the USPTO. This not only safeguards their brand and reputation but also provides legal recourse against unauthorized use of the trademark.

South Dakota’s copyright law protects original works of authorship, including literary, dramatic, musical, artistic, and certain other intellectual works. This encompasses written content, software, web content, films, sound recordings, images, and various forms of creative expression.

When you create a new work in South Dakota, copyright protection is automatically granted to you as the creator. As the owner of exclusive rights to distribute, reproduce, create derivative works, and sell intellectual property, you have the legal authority to control the use of your work.

However, registering your copyright with the U.S. Copyright Office in South Dakota can provide additional legal protection and serve as evidence of ownership. Registering your copyright in South Dakota can help protect your work against infringement and provides a way to enforce your rights through the court system if necessary.


If you invent a new product or piece of machinery in South Dakota, obtaining a patent is crucial. A patent grants exclusive rights to the holder, preventing others from making, selling, or importing the patented item for a specified period.

The patent application process is complex and can take up to five years to complete, so initiating it early is advisable if you have a unique invention that requires protection. Patent applications are submitted to the United States Patent and Trademark Office (USPTO).

By protecting your intellectual property in South Dakota, you can safeguard your brand, products, and creations, ensuring your business maintains a competitive edge and continues to flourish.

File a Trademark with Bizee

Step 7: Set Up Your Payment Infrastructure in South Dakota

To ensure that your South Dakota-based business is prepared to serve customers immediately upon registration, it’s vital to establish a seamless and hassle-free payment acceptance system.

Several payment processing services are available, offering user-friendly interfaces and effortless integration with your website or point-of-sale (POS) system. Square, Stripe, and PayPal are among the popular choices, providing flexible and customizable systems that align with your business goals.

These payment processors allow you to accept various payment methods, including credit and debit cards, ACH transfers, digital wallets like Apple Pay and Google Pay, and more. By selecting a reliable payment processing service, you can offer your customers the convenience of paying with their preferred methods through a secure platform, ensuring a smooth transaction experience for all parties involved.

In addition to choosing a payment processor, it’s crucial to establish sales tax compliance in South Dakota. This entails obtaining a South Dakota Sales Tax License from the South Dakota Department of Revenue, granting you the authority to collect sales tax on taxable goods and services.

Once your payment infrastructure is in place, your South Dakota-based business will be well-prepared to serve customers and generate revenue efficiently and securely.

By following these steps, you will be on the path to establishing a legally compliant business in South Dakota.
