How to File
Choose a Business Name
Select a unique name for your LLC that includes 'Limited Liability Company,' 'LLC,' or 'L.L.C.' and is distinguishable from all other registered entities in South Dakota. Use the South Dakota Secretary of State's online name search tool to verify availability.
30 minutes
Appoint a Registered Agent
Designate a registered agent with a physical street address in South Dakota (P.O. boxes are not permitted) who is available during normal business hours to receive legal and official documents on behalf of the LLC. The agent can be an individual resident or a registered commercial agent service.
15-30 minutes
File Articles of Organization
Submit the Articles of Organization (Form LLC-1) to the South Dakota Secretary of State online via the SD OneStop portal or by mail, along with the $150 filing fee. The form requires the LLC name, registered agent information, organizer details, and principal office address.
30-45 minutes
Create an Operating Agreement
Although not legally required by South Dakota law, drafting an Operating Agreement is strongly recommended to outline ownership structure, member responsibilities, profit distribution, and management procedures. This document is kept internally and not filed with the state.
1-3 hours
What's Next After Filing
Once your LLC is officially formed, you'll want to complete these important steps:
- •Obtain an EIN from the IRS — Apply for a Federal Employer Identification Number (EIN) through the IRS website at no cost — this is required to open a business bank account, hire employees, and file federal taxes. Single-member LLCs with no employees may use the owner's SSN, but an EIN is still recommended.
- •Register for State Taxes and Licenses — Register with the South Dakota Department of Revenue if your LLC will collect sales tax or has employees subject to state withholding. Obtain any required local or professional licenses and permits relevant to your business activities and location.
- •File Annual Reports — Submit the South Dakota LLC Annual Report to the Secretary of State each year by the first day of the second month following the LLC's anniversary month, accompanied by the $50 annual report fee. Keeping this filing current maintains the LLC's good standing.
Advantages
- ✓No state corporate income tax or personal income tax, making South Dakota highly tax-friendly for LLC members
- ✓No franchise tax, keeping ongoing state costs minimal at just the $50 annual report fee
- ✓Strong asset protection and privacy laws, with South Dakota not requiring member or manager names on public filings
- ✓Flexible management structure allowing single-member or multi-member LLCs with minimal bureaucratic requirements
- ✓Business-friendly regulatory environment with straightforward formation process and low compliance burden
Considerations
- •Registered agent with a physical South Dakota address is required, which may add cost for out-of-state owners using a commercial service
- •Annual report must be filed on a rolling anniversary-based schedule rather than a fixed calendar date, which can be easy to miss without proper tracking
- •South Dakota has a relatively small local market and limited state-specific business resources compared to larger states
