How to Start a Business in South Dakota:

1. Determine your business structure.

Choosing the right legal structure for your company is important. Your choice will have an impact on taxes, paperwork, personal liability, and your ability to raise funds.

You can choose from the following legal structures:

A sole proprietorship is the simplest structure and usually involves one individual who is solely responsible for the enterprise while a partnership is suitable for businesses with two or more owners. A corporation is a standalone entity with shareholders while a Limited Liability Company (LLC) is the most popular type because of minimal paperwork, flexibility, tax benefits, and simple implementation process. LLC business owners are not obligated to file a corporate tax return.

Businesses are regulated by South Dakota state laws and must be registered through the South Dakota Department of State website.

2. Write a business plan.

Your business plan is the foundation of your new business and will serve as an invaluable guide for how to structure, run and grow your company. The business plan must meet your needs and can fall into one of two common categories: traditional or lean startup.

The traditional plan is very detailed, takes more time to write, and is quite comprehensive while the lean startup plan is high-level and fast to write.

A strong business plan can help you get funding and makes opening a new business easier. You can consult with the South Dakota Governor’s Office of Economic Development, a free service that offers business planning and consulting for small business owners in South Dakota.

3. Sign up for business banking.

Your business and personal finances must be kept separate to maintain accurate records. With a business bank account, you can easily obtain statements and access products that would not be available to you as an individual.

4. Seek funding.

Opening a new business often requires capital. If you are unable to fund your new business, you will need to take out a loan. There are three common ways to fund your business: commercial loans, business lines of credit and small business loans.

A popular organization that can assist you with small business loans in South Dakota is Grow South Dakota.

5. Decide on a business name.

Make a list of names that you like and perform a Google search to find any conflicts with other South Dakota business names.

Once this is done, you will need to do a trademark search to ensure that the business name that you chose has not already been trademarked. You can perform the trademark search at the U.S. Patent and Trademark Office and the Trademark Electronic Search System. These databases have a comprehensive list of business names that are registered together with their classification.

After you have confirmed that your business name is not trademarked, you need to check the South Dakota Secretary of State website to ensure that your business name is not the same or similar to another corporation registered in South Dakota.

If you are satisfied that your business name is available, you can then register it on the U.S. Patent and Trademark Office website. You can check out our guide on How to Name a Business to assist you with naming your business.

Once you have found a suitable name, make sure to register the matching web domain and social media handles, should you wish to market your business online. You can use our How To Register a Domain Name guide to assist you with the process.

6. Request an Employer Identification Number (EIN).

Every business needs to have an Employer Identification Number (EIN). Registering for an EIN is very easy—all you need to do is go to the IRS website. You can complete the application online, and save your EIN confirmation notice once you receive a number from the IRS.

7. Acquire business licenses and permits.

The state of South Dakota does not require businesses to have a statewide business license. You may, however, require a specific business license depending on the type of business that you start. You can consult with the South Dakota Governor’s Office of Economic Development to check on specific business licenses and permits that you may require. You can also get more information here.

8. Hire employees.

To start hiring you will need to register at the South Dakota Department of Labor & Regulation. Each employee will need to be registered within 20 days of starting work in accordance with the Personal Responsibility and Work Opportunity Act.

The South Dakota Human Relations Act protects employees against discrimination on the basis of age, race, creed, color, sex, sexual orientation, gender identity, national origin, religion, or disability.

With reference to the pre-employment screening process in South Dakota, an employer is entitled to view a job applicant’s criminal history and obtain the relevant records from the criminal justice system.

9. Check your business employer requirements.

Business employer requirements are specific to the type of business that you are starting and include various labor, safety and tax obligations that need to be met. You should consider hiring a tax or business attorney to ensure your business is fully compliant with the laws in South Dakota.
