1. Search Your LLC Name

The first step in forming your LLC in South Dakota is to choose a name for your company. The name of your LLC must meet several requirements set forth by the state, and it’s important to get this right from the outset to avoid delays later on. Here’s what you need to keep in mind when choosing your LLC name:

  • The name must include the words “Limited Liability Company,” “LLC,” or “L.L.C.”
    These terms help make it clear that your business is a limited liability company, which is crucial for legal and branding purposes.
  • The name must be distinguishable from other businesses registered in South Dakota.
    This ensures there are no conflicts with existing companies and that your business name is unique.
  • Restricted words cannot be included unless you have the proper licenses.
    For instance, you cannot include words like “bank,” “insurance,” or “trust” unless your business is in the respective industry and has the appropriate certifications.
  • The name should be professional and reflect your business values.
    While this is not a legal requirement, choosing the right name is essential for building your brand and attracting customers.

Once you have a name in mind, it’s time to check its availability. South Dakota provides a business name search tool on the Secretary of State’s website, where you can easily determine if the name you’ve chosen is already in use. You’ll want to make sure no one else is using the same or a similar name to avoid potential legal issues.

If the name you want is available, you can go ahead and reserve it with the state for a fee of $25. This reserves the name for 120 days, which gives you time to finalize your LLC formation paperwork. However, you can skip the reservation if you are ready to file your Articles of Organization immediately.

2. Choose a Registered Agent

A Registered Agent is a person or business that is designated to receive legal documents and official correspondence on behalf of your LLC. This is an essential step in forming your LLC in South Dakota, as it ensures you stay informed of any legal actions or business-related notifications.

South Dakota law requires all LLCs to designate a Registered Agent who meets the following requirements:

  • A physical address in South Dakota.
    Your Registered Agent must have a physical street address in South Dakota, as P.O. Boxes are not accepted.
  • Availability during normal business hours.
    The Registered Agent must be available at the provided address during business hours to receive legal documents.

You can serve as your own Registered Agent, but many business owners choose to hire a professional Registered Agent service. A professional service can ensure privacy (as your personal address won’t be listed in public records) and provide reliable document delivery services.

One highly recommended service is Northwest Registered Agent. They are known for their top-notch customer service and have a reputation for keeping their clients’ information private and secure. You can also find many other Registered Agent services that can handle this part of your business operations for you.

It’s important to choose the right Registered Agent for your LLC, as failing to maintain a Registered Agent could lead to your LLC losing good standing in the state and facing potential penalties.

3. File Articles of Organization

Once you have your name and Registered Agent in place, you can officially start your LLC by filing the Articles of Organization with the South Dakota Secretary of State. The Articles of Organization is a document that legally establishes your LLC.

To file, you will need to submit basic information about your LLC, such as:

  • LLC Name
    The name you’ve chosen for your LLC.
  • Registered Agent’s Name and Address
    The name and physical address of your Registered Agent in South Dakota.
  • LLC’s Duration
    In most cases, your LLC will be set up to exist indefinitely unless you specify a different duration.
  • The Principal Office Address
    The address of your LLC’s main office. This can be the same as your Registered Agent’s address, but it doesn’t have to be.
  • Organizer Information
    The name and address of the person filing the Articles of Organization. This is typically you or a business attorney.

The filing fee for Articles of Organization is $150 if you file online and $165 if you file by mail. Online filing is quicker, typically processed the same day, while mail submissions can take up to 5 business days. Filing online is also easier and more efficient, so it’s a good option if you’re in a hurry.

Once your Articles of Organization are filed and accepted, your LLC is officially formed. You’ll receive confirmation from the Secretary of State’s office, and your business will be legally recognized in South Dakota.

4. Create an Operating Agreement

While not required by South Dakota law, it is highly recommended that your LLC creates an Operating Agreement. This internal document outlines the management structure, ownership, roles, and operating procedures of your LLC.

Here’s why it’s important to have an Operating Agreement:

  • Clarifies ownership and roles within the LLC, especially if there are multiple members.
  • Helps avoid conflicts by setting out rules for how the business will be managed and how decisions will be made.
  • Protects your limited liability status.
    Without an Operating Agreement, courts could disregard your LLC’s limited liability protections if there’s a legal dispute.

If you’re the only member of your LLC, you can create a simple Operating Agreement that outlines your responsibilities and expectations. For multi-member LLCs, the Operating Agreement should be more comprehensive and cover decision-making processes, profit-sharing, dispute resolution, and the exit strategy.

5. Obtain an EIN (Employer Identification Number)

The next step in the process is to obtain an Employer Identification Number (EIN) from the IRS. The EIN is like a social security number for your business and is used to identify your LLC for tax purposes.

You’ll need an EIN if your LLC will have employees or if you plan to open a business bank account. Even if you won’t have employees, getting an EIN is recommended to separate your personal and business finances.

Obtaining an EIN is free and can be done online through the IRS website. The application process is quick, and you’ll receive your EIN immediately after submitting the form. Once you have your EIN, make sure to keep it in a safe place for future use.

What to Do After Your LLC Is Approved

File Your Annual Report

South Dakota requires all LLCs to file an annual report to maintain good standing. This annual report updates the state on your business’s current contact information and ensures that your LLC remains in compliance.

The filing fee for the annual report is $50 for online submissions and $65 for paper submissions. The annual report is due by the first day of the anniversary month of your LLC’s formation. For example, if you formed your LLC on April 15, the report will be due on April 1 each year.

Failure to file the annual report on time can result in penalties, and if left unchecked, your LLC could be administratively dissolved by the state.

Maintain Good Standing

After your LLC is formed, it’s important to keep up with ongoing maintenance to avoid losing your good standing. This includes:

  • Filing your annual report on time each year.
  • Keeping your Registered Agent information updated.
  • Maintaining accurate records for your business.

You’ll also want to pay attention to any additional requirements based on the nature of your business, such as licenses, permits, and tax filings.

How Will My LLC Be Taxed?

South Dakota has one of the most business-friendly tax systems in the country. Here’s what you need to know about how your LLC will be taxed:

  • No state income tax
    South Dakota does not impose a state income tax, meaning your LLC will not have to pay taxes on its income to the state.
  • Sales tax
    South Dakota imposes a 4.5% state sales tax, and local municipalities may impose additional sales taxes. You will need to register for a sales tax permit if you are selling taxable goods or services in the state.
  • Federal tax
    At the federal level, your LLC will be taxed based on its classification. A single-member LLC is taxed as a sole proprietorship, while a multi-member LLC is taxed as a partnership. If you wish, you can elect for your LLC to be taxed as an S-Corporation or C-Corporation by filing the appropriate forms with the IRS.
