Introduction

Starting an LLC in South Dakota is a smart move if you want to protect your personal assets and enjoy some flexibility in management. First, you need to choose a unique name for your LLC. Make sure it complies with South Dakota’s naming requirements, which means it should include “Limited Liability Company” or abbreviations like “LLC.”

Once you have a name, you file the Articles of Organization with the South Dakota Secretary of State. This document is straightforward and includes basic information about your LLC, like its name, address, and the names of its members. There’s a filing fee involved, so be prepared for that.

Obtain an Employer Identification Number (EIN) from the IRS, especially if you plan to hire employees or if you want to open a business bank account. And just like that, you’re well on your way to launching your LLC in South Dakota! 

To start an LLC in South Dakota:

1. Understand What an LLC Is and Why You Need It

You want to form an LLC because it’s a good way to protect yourself and your personal assets, like your house or car, if something goes wrong with your business. Think of an LLC as a shield between your personal life and your business. If your business has debt or gets sued, people can’t come after your personal stuff—they can only go after your business.

It also makes your business look more professional. If you’re dealing with customers or suppliers, having an LLC in your business name makes you seem more legit, instead of just being an individual running a business.

2. Choose a Name for Your LLC

The first thing you need to do is come up with a name for your LLC. This name has to be unique. In South Dakota, nobody else can have the same business name as yours. You can’t use something like “Joe’s Plumbing LLC” if someone else in South Dakota already has that name.

So, pick a name that’s memorable and reflects what your business does. After you pick a name, you need to check if it’s available. South Dakota makes it easy. You can go to the South Dakota Secretary of State website and search its business database. Type the name you want to use and see if anyone else already has it.

Another thing to know is that the name of your business must include “LLC” or “Limited Liability Company” somewhere. It’s required by law. For example, if you’re opening a bakery, you could name it “Fresh Bakes LLC” or “Fresh Bakes Limited Liability Company.” 

3. Appoint a Registered Agent

This part sounds a bit complicated, but it’s really not. Every LLC in South Dakota needs to have something called a “registered agent.” The registered agent is the person or company that agrees to accept legal papers on behalf of your LLC. If someone sues your business, the registered agent is the one who gets the legal documents.

You can be your own registered agent, but there’s a catch—you must have a physical address in South Dakota and be available during normal business hours to accept mail or legal notices. You can’t use a P.O. Box for this, and it can’t be just any address. It has to be somewhere that someone can physically deliver papers.

Now, if you don’t want to be the registered agent yourself, you can hire a company to do this for you. There are services out there that charge a small yearly fee to act as your registered agent. That way, you don’t have to worry about missing important legal mail.

4. File Articles of Organization

Here’s where things start to feel official. You must file Articles of Organization with the South Dakota Secretary of State. This document is what officially forms your LLC in South Dakota.

You can file the Articles of Organization online, which makes things easier and faster, or you can send it in by mail if you prefer. But know what goes into this document so you can understand what’s happening.

The name of your LLC: Remember, it must include “LLC” in the name.

The name and address of your registered agent: Either your address or the company you hired to be your registered agent.

  • The duration of your LLC: If you want the LLC to exist forever, you can mark it as “perpetual.” Most people go with this option unless they have a specific end date for their business.
  • Your business address: This can be your home address if you don’t have a separate office. But remember, this address is public, meaning anyone can see it.

Once you fill out this form, you pay a filing fee to the state. As of now, the filing fee in South Dakota is $150 if you do it online and $165 if you do it by mail.

5. Get an EIN (Employer Identification Number)

Now, after you’ve filed your Articles of Organization, you need an EIN, which stands for Employer Identification Number. This is like a Social Security Number, but for your LLC. It’s given to you by the IRS, and you need it to do things like open a bank account for your business, file taxes, and hire employees if you decide to go down the road.

Getting an EIN is free, and you can do it online through the IRS website. It’s a pretty simple process, and the IRS gives you the number right after you apply. Even if you don’t plan on having employees, you need this number for your LLC for tax purposes.

6. Open a Business Bank Account

You’ve probably heard that it’s important to keep your personal finances separate from your business finances. That’s especially true with an LLC. You want to open a separate business bank account so that all the money from your business goes in and out of this account only.

Having a business bank account helps you keep your records clean, makes it easier to file taxes, and keeps your personal liability protection in place. If you mix personal and business money together, the courts might say you’re not really treating your LLC like a separate entity, which could hurt you if someone ever sues you.

When you go to open a business account, you need a few things:

  • Your EIN number
  • A copy of your LLC’s Articles of Organization
  • Your Operating Agreement (some banks ask for this)
  • Once you open this account, use it for everything related to your business—buying supplies, paying bills, and accepting payments from customers.

7. File for Necessary Licenses and Permits

Depending on the type of business you’re starting, you may need to get certain licenses or permits. South Dakota doesn’t have a general state business license, but some cities or counties within South Dakota may require you to have a local business license.

For example, if you’re opening a restaurant, you need health permits and food safety licenses. If you’re in construction, you might need a contractor’s license. So, check with your local city or county offices to find out what specific permits apply to your business.

Also, if you’re selling goods, you might need a sales tax license from the South Dakota Department of Revenue. This allows you to collect sales tax from customers, which you need to send to the state.

8. Comply with South Dakota Taxes

South Dakota is actually one of the most business-friendly states when it comes to taxes because it doesn’t have a state income tax or a corporate tax. That means your LLC won’t be paying state-level income taxes on the money it makes. This is a huge benefit compared to other states.

However, you need to pay federal taxes, and if you have employees, you have to deal with payroll taxes. If your LLC sells products, you also need to collect and pay sales tax.

Each year, you must file an Annual Report with the South Dakota Secretary of State. This report updates the state of your business’s status. You file it online, and it currently costs $50. The deadline to file this report is the anniversary month of when you formed your LLC. So, if you started your LLC in October, you need to file your annual report every October.

9. Maintain Your LLC

After you’ve done all this, the last thing you need to know is how to keep your LLC in good standing. The good news is, maintaining an LLC in South Dakota isn’t hard. You just need to make sure you:

  • File your Annual Report every year
  • Pay any required taxes (like sales taxes or payroll taxes if you have employees).
  • Keep your business records up to date
  • Follow the rules you set in your operating agreement.

As long as you do these things, your LLC stays active, and you continue to get the protection and benefits it offers.

Recap

Starting an LLC in South Dakota is pretty straightforward! First, choose a unique business name for your LLC that includes “LLC” in it. Select a registered agent—someone who can receive legal papers on behalf of your LLC, whether it’s you or a professional service.

Then, file the Articles of Organization with the South Dakota Secretary of State and pay the filing fee. After that, draft an Operating Agreement to outline how your LLC is going to be managed, even though it’s not required by law. Get an Employer Identification Number (EIN) from the IRS if you plan to hire employees or open a business bank account. 

Also, stay on top of South Dakota taxes; even though there are no state income or corporate taxes, you need to collect sales taxes if applicable and file your federal taxes. File an Annual Report every year to keep your LLC in good standing with the state. That’s it! You’re all set to launch your LLC.
