The 4 steps in South Dakota
Pick a name that works in South Dakota
Your name must be distinguishable from other South Dakota businesses and include a designator like “LLC” or “Limited Liability Company.” Search the state's business database before you file.
File the paperwork
You file Articles of Organization with the Secretary of State online through SOS Business Services or by mail. The filing fee is $150. Also write a simple operating agreement — it's free, and it keeps your liability protection clear.
Get your free EIN
Apply at IRS.gov and get your Employer Identification Number immediately, for free. You'll need it for taxes and your business bank account.
Open a business bank account
Bring your approved Articles of Organization, EIN, and operating agreement. Keeping business money separate is what makes the liability protection hold.
Optional: name a registered agent service
Every South Dakota LLC needs a registered agent with a physical address in the state. You can be your own for free — or pay a service to keep your address private. Learn how registered agents work.
South Dakota has no state income tax for individuals or businesses, which makes it a popular low-tax state.
