How Do I Register a Business in South Dakota?

As promised, here are all the steps required for you to open a business in South Dakota.

Name Your Business

One of the first steps to registering a business is finding the right name for it.

You have a lot of freedom when it comes to choosing your business name, but you also have to comply with a few rules imposed by the state.

One of these rules is ensuring that your business has a unique name that’s not occupied by another business in the country. To help you determine this, you can do a business entity search on the South Dakota Secretary of State website.

You also have to insert a word in the name that indicates what kind of business entity your business has. For instance, corporations need to include “Incorporated”, “Inc.” or another abbreviation.

You can also reserve your name to ensure that nobody else in the state grabs hold of it.

Choose a Business Structure

Along with naming your business, you should also choose its business structure. In South Dakota, the main business structures are:

  • Sole proprietorship
  • Partnership
  • LLC
  • Corporation

LLCs and corporations are ideal for people who have a larger budget and place a high value on limited liability – protection of the owner’s assets in case of a lawsuit or claim.

File Articles of Organization

If the option you’re going with is forming an LLC, you’ll need to file articles of organization with the South Dakota state. This document is indispensable in the formation of your business because it contains important information about your business, like your location and registered agent.

The fee for filing articles of organization is $150.

File Articles of Incorporation

Those who have decided to start a corporation will need to file articles of incorporation with the state. This document is similar to articles of organization, but it has additional information about certain aspects of the business that can’t be found in an LLC.

The filing fee for articles of incorporation is $150.

Get All the Necessary Licenses and Permits

To ensure that your business follows every regulation, you’ll need to check to see if you need any additional licenses and permits for your business to operate.

South Dakota doesn’t have a general business license, but there are some licenses you might need to get depending on what industry your business is in.

For instance, if your business includes selling services, you might need to obtain a sales tax license.

To check if you have all the required licenses and permits, you can always do a business license search online.

Get an Employee Identification Number

Last but not least, depending on your business, you might need to obtain an EIN.

Businesses that have hired employees and/or are taxed separately from their owners are required on a state level to get an EIN. For all the other businesses, it’s an optional step.

Even if your business doesn’t require it, there are many benefits to getting an EIN, such as making it easier for you to open a business bank account and do taxes.

You can apply for an EIN on the IRS website. The application is completely free and easy to complete.

FAQs

Where can I do a South Dakota Business Entity Search?
