Steps to Forming an LLC in South Dakota

Forming an LLC in South Dakota is a straightforward process that can be completed with a few simple steps. By following the proper legal procedures, you’ll gain liability protection, tax advantages, and the flexibility needed to run your business efficiently. Here are the key steps to get started:

1. Search Your LLC Name

The first step in starting an LLC in South Dakota is choosing a name for your business. Your LLC name must be unique and distinguishable from other registered businesses in the state. It’s essential to make sure that your name isn’t already taken to avoid legal issues or confusion.

Name Requirements:

  • The name must include “Limited Liability Company,” “Limited Company,” “LLC,” “L.L.C.,” “LC,” or “L.C.”
  • You can also use abbreviations like “Ltd.” or “Co.” to replace “Limited” and “Company,” respectively.
  • Your name cannot be misleading or imply that your LLC is a different type of entity (such as a corporation or bank).

The South Dakota Secretary of State’s website provides a business entity search tool where you can check the availability of your desired LLC name. It’s best to perform this search early in the process to ensure you don’t run into any delays. If the name is already in use, you’ll need to choose a different one or modify it to make it unique.

If you’re set on your name but want to secure it before submitting your LLC paperwork, you can reserve it for a small fee. Reserving a name is optional and not required to form your LLC, but it guarantees that no one else can use that name while you prepare your paperwork.

2. Choose a Registered Agent

A registered agent is a person or business entity that acts as your LLC’s official point of contact with the state. The agent receives legal documents, government notices, and other important mail on behalf of your LLC. It is a legal requirement for all LLCs in South Dakota to have a registered agent.

Who Can Be a Registered Agent?

A registered agent must meet specific criteria:

  • South Dakota resident: If you choose an individual to serve as your agent, they must be a resident of South Dakota with a physical address in the state.
  • Business entity: You can also appoint a company that offers registered agent services, as long as they are authorized to conduct business in South Dakota.
  • Yourself: If you have a physical address in South Dakota, you can be your own registered agent. However, this can create privacy concerns since the registered agent’s address becomes public information.

Many entrepreneurs prefer using a professional registered agent service to maintain privacy and avoid potential missed mail or compliance issues. One of the most popular services in South Dakota is Northwest Registered Agent. They specialize in LLC formation and offer excellent customer service and privacy protection.

3. File Articles of Organization

The Articles of Organization is the official document that creates your LLC in South Dakota. This document includes essential details about your LLC, such as its name, address, registered agent, and members.

Filing Articles of Organization is a relatively straightforward process in South Dakota. You can file online, by mail, or in person. The South Dakota Secretary of State offers a simple online portal where you can submit your Articles of Organization and pay the required filing fee.

Filing Details:

  • Filing Fee: $150 for online filing and $150 for mail filings.
  • Processing Time: If filed online, your LLC is typically approved immediately. Mail filings may take 1-2 business days.
  • Where to File: You can file your Articles of Organization through the South Dakota Secretary of State’s website.

The form asks for basic information, such as:

  • The LLC name
  • The LLC’s address (must be a physical address in South Dakota)
  • The name and address of your registered agent
  • The duration of the LLC (most LLCs are formed to exist indefinitely, but you can specify a certain duration if needed)
  • Whether your LLC will be managed by members or managers (this refers to how the business will be run, either by the owners or by appointed managers)

Once the Secretary of State processes your Articles of Organization, they will send you confirmation, and your LLC will officially be formed.

4. Create an Operating Agreement

Although South Dakota does not require LLCs to have an Operating Agreement, it is highly recommended to create one. An Operating Agreement is an internal document that outlines the management structure, ownership, responsibilities, and operating procedures of your LLC.

While not legally required, an Operating Agreement can help prevent disputes among members and provide clarity in business operations. It’s also essential for opening business bank accounts and obtaining financing. Most banks require an Operating Agreement to establish your business account.

Some key points to include in the Operating Agreement:

  • Ownership Structure: Specify each member’s percentage of ownership in the LLC.
  • Management: Outline how the LLC will be managed, whether by members or by appointed managers.
  • Member Roles: Define the responsibilities and powers of each member.
  • Profit Distribution: Specify how profits and losses will be shared among members.
  • Decision-Making Process: Set guidelines for how decisions will be made, including voting rights.

5. Get an EIN for Your LLC

An Employer Identification Number (EIN), also known as a Federal Tax Identification Number, is required for tax purposes. If you plan to hire employees, open a business bank account, or apply for certain permits, you’ll need an EIN.

Getting an EIN is free and easy through the Internal Revenue Service (IRS) website. You can apply online, and you will receive your EIN immediately upon completion of the application.

If you have a single-member LLC, you may not need an EIN if you’re operating as a sole proprietor and don’t plan to hire employees. However, it’s generally a good idea to obtain one, as it helps separate your personal and business finances, streamlining tax reporting and protection.

After Your LLC Is Approved: Ongoing Responsibilities

Once your LLC is formed, there are several ongoing obligations and maintenance requirements to keep your LLC in good standing with the state.

How Much Does a South Dakota Annual Report Cost?

South Dakota requires LLCs to file an annual report to maintain their active status. The report provides updated information about your business, including any changes in address, ownership, or business activities.

The filing fee for the Annual Report is $55 if filed online. If you file a paper report, the fee is $70.

When Is the Annual Report Due?

Your LLC’s annual report is due on the first day of the anniversary month of your LLC’s formation. For example, if your LLC was formed on April 15, 2024, your first annual report will be due on April 1, 2025.

It’s important to keep track of your filing deadline to avoid late fees or penalties. The South Dakota Secretary of State sends reminders to LLCs about their upcoming annual reports.

How Do I File My LLC Annual Report?

You can file your annual report online or by mail. The South Dakota Secretary of State provides an easy-to-use online portal for filing.

  • Online Filing: Visit the Secretary of State’s website, enter your business ID number, and follow the instructions to complete the filing.
  • Paper Filing: You can download the paper form from the Secretary of State’s website, complete it, and mail it to the address provided on the form.

How Will My LLC Be Taxed?

South Dakota is known for being business-friendly, and one of the biggest benefits for LLC owners is the lack of a state income tax. South Dakota does not impose a state income tax on businesses or individuals, which can be a significant advantage compared to other states.

However, your LLC may still be subject to federal taxes, including self-employment tax, income tax, and other applicable taxes. If you have employees, you will also need to comply with federal employment tax requirements, including withholding and paying Social Security, Medicare, and unemployment taxes.
