Types of Business Entities in South Dakota
Choosing the right business structure is an important step when learning how to start a business in South Dakota. The type of entity you select affects your taxes, legal responsibilities, and how you manage your business. Below are the most common types of business entities recognized in the state, each with its own advantages.
Sole Proprietorship
This is the simplest business structure. It’s easy to form and does not require formal South Dakota business registration with the Secretary of State. The owner and the business are legally the same, meaning the owner is personally responsible for debts and liabilities. It’s ideal for freelancers or very small businesses just starting out.
General Partnership
A general partnership involves two or more individuals sharing ownership. Like a sole proprietorship, it has minimal startup requirements but does not provide liability protection. A written partnership agreement is recommended. Registration may still be needed for business names or tax purposes.
Limited Liability Company (LLC)
An LLC is a popular choice for small to mid-sized businesses. It provides liability protection like a corporation but has simpler management and tax flexibility. To form an LLC, South Dakota business registration with the Secretary of State is required. This structure suits business owners who want personal asset protection without complex formalities.
Corporation (C Corp or S Corp)
Corporations are separate legal entities from their owners. They provide strong liability protection and are suitable for businesses that plan to raise capital or issue shares. C Corps are taxed separately, while S Corps allow profits and losses to pass through to shareholders. Corporations must file formal documents as part of how to start a business in South Dakota.
Limited Partnership (LP) and Limited Liability Partnership (LLP)
These are less common but useful for specific business models. LPs have general and limited partners, while LLPs allow all partners to have limited liability. These entities must also register with the state.
When deciding how to start a business in South Dakota, consider your business size, risk level, tax preferences, and long-term goals. The right entity helps protect your assets and ensures smoother operations.
Step-by-Step Guide to South Dakota Business Registration
Starting a business in South Dakota is a straightforward process, but completing each step correctly is essential to staying compliant with state regulations. Follow this guide to complete your South Dakota business registration:
Step 1: Choose Your Business Structure
Decide on the legal entity that fits your goals (LLC, Corporation, Sole Proprietorship, etc.). Your choice affects taxes, liability, and paperwork requirements. It also impacts how your business is managed and how profits are distributed.
Step 2: Name Your Business and Check Availability
Choose a unique business name and conduct a name search through the South Dakota Secretary of State (SOS) website to ensure it’s not already in use. Ensure the name complies with state naming rules for your chosen entity type. If your preferred name is available, you may reserve it for a limited time before filing. This step helps avoid legal conflicts and branding issues later on.
Step 3: Register Your Business with the State
File the appropriate formation documents with the South Dakota SOS business registration portal. Important documents include:
- LLCs file Articles of Organization
- Corporations file Articles of Incorporation
- Sole proprietors and partnerships may need to file a DBA (Doing Business As) name
You can complete this step online through the South Dakota SOS business registration portal or submit paper forms. Fees vary based on entity type and filing method.
Step 4: Apply for an EIN (Employer Identification Number)
Obtain an EIN from the IRS for tax purposes. It’s required to hire employees, open a business bank account, and file federal and state taxes. Many banks and licensing agencies require an EIN even if you don’t plan to hire employees. The application is free and only takes a few minutes to complete online.
Step 5: Register for a South Dakota Sales Tax License
You must register with the South Dakota Department of Revenue to get a sales tax license if you sell taxable goods or services. This applies to both in-state and remote sellers who meet the economic nexus threshold. Once approved, you’ll receive your tax license number and filing schedule. Be sure to post your license in a visible area at your place of business.
Step 6: Obtain Required Licenses and Permits
You may need local or industry-specific licenses depending on your business type and location. These might include zoning permits, health permits, or professional licenses. Requirements vary widely by location and industry. Failing to secure the correct permits could lead to fines or delays.
Step 7: Open a Business Bank Account
Separate your business finances from personal accounts. Use your EIN and state registration documents to open a business checking account. Most banks require your EIN and registration documents to open an account. It’s also a good idea to apply for a business credit card to start building credit.
Step 8: Stay Compliant with Ongoing Requirements
Submit annual reports if required, pay taxes, renew licenses, and keep your business records updated with the South Dakota SOS.
Ongoing Compliance After South Dakota Business Registration
Completing your initial registration is just the beginning. Ongoing compliance is essential to keep your business in good standing with South Dakota state authorities. Most registered businesses must file an annual report with the South Dakota SOS. This report is due each year in the anniversary month of your business’s formation and includes a filing fee of $50 for online and $65 for paper filing. Failure to file can result in a penalty of $50.
In addition to annual reports, businesses may need to maintain appropriate licenses, renew applicable permits, and stay current on state and local tax filings. Businesses registered for sales tax must file returns regularly based on their assigned filing frequency. LLCs and corporations should also keep accurate records of business decisions and meetings to comply with state laws.
Staying compliant after completing your state of South Dakota business registration helps avoid disruptions and keeps your business legally active.
Do You Need a Business License in South Dakota?
Many new entrepreneurs often confuse South Dakota business registration with business licensing. Business registration involves officially creating your business entity with the state, such as forming an LLC or corporation, or registering a trade name. This step legally establishes your business and allows you to operate under a recognized structure.
Completing your South Dakota state business registration ensures your business is acknowledged by the Secretary of State and other state agencies.
Business licensing, on the other hand, involves specific permits or approvals you may need to operate legally in certain industries or locations. These may include health permits, professional or occupational licenses, contractor licenses, or local zoning approvals. Not every business in South Dakota requires a state-issued business license.
However, depending on your industry, location, or the nature of your operations, you may need additional licenses or permits at the local, county, or state level. To determine if your business requires specific licenses or permits, consult the South Dakota Department of Revenue: dor.sd.gov/businesses. Additionally, local city or county offices can provide information on local licensing requirements.
