Appoint a Registered Agent
Before you officially file to create your South Dakota LLC, you will need to decide who your South Dakota registered agent will be. A registered agent is a business's legal appointee to receive notice of lawsuit and other legal or government notices.
State law requires every LLC to have a registered agent. The registered agent is designated when you file South Dakota articles of organization with the South Dakota Secretary of State.
Our reliable registered agent service fulfills this requirement. You get:
- Same-day documents from our local office in Watertown
- Immediate online access to state forms with our address and, where required, our signature
- Annual fees from $89 to $99 per state with no additional charges

Submit original and one copy.
Establish Company Records
Your LLC must keep correct and complete books and records. Your filed articles of organization are the first documents for your LLC’s records. Your LLC will generate many other official records such as:
- Meeting minutes
- Operating agreement
- EIN verification letter
- Amendments and other filings made to the LLC throughout its lifetime
Organizations need a secure, centralized tool for managing and accessing sensitive records. Our Records Manager software offers a simple, efficient way for LLCs to store records, track members and managers, and customize meeting notifications.
Create the Operating Agreement
Draft an Operating Agreement (potentially using a template) which is the governing document for the LLC. It defines the formalities of how the LLC will run itself such as holding an annual meeting. You will review and adopt the agreement at your organizational meeting.
Hold the Organizational Meeting
The first meeting of the members of the LLC is the organizational meeting. You will need your filed articles of organization and your operating agreement in order to conduct this meeting. Keep minutes of this meeting and store them in your company record book.
Get a Federal Employer Identification Number (EIN)
If your LLC has more than one member or will hire employees, it must obtain an EIN. An EIN is also often required to open a bank account.
Agency: Internal Revenue Service (IRS) Form: Filing Method:
Mail, phone, fax, or online.
Immediately online or by phone. 4 business days by fax. 4-5 weeks by mail.
The IRS website is only available during certain hours. Print your EIN before closing your session. For additional guidance, see IRS Pub 1635: Understanding Your EIN.
Get South Dakota State Tax Identification Numbers/Accounts
South Dakota does not have a corporate, unitary, or personal income tax. However, businesses may be subject to one or more other state taxes. You can use the South Dakota Tax Application to apply for the following tax licenses: Contractors' Excise, Manufacturer, Sales, Use, Wholesaler, and all Motor Fuel tax types.
Consider Electing S-Corp or C-Corp Taxation
By default, your LLC receives pass-through taxation and the vast majority of LLCs keep this tax classification. Some LLCs benefit from electing S-Corp or C-Corp tax treatment:
- S-Corp treatment can help owner-employees who earn more than ~$75,000 per year save on self-employment taxes. File Form 2553: S-Corp Election.
- C-Corps suffer from double taxation: the corporation pays taxes on profits then members pay taxes on their distributions. If profits exceed $250,000 per owner, you provide employee benefits, or you will re-invest most of your profit in the business, you may benefit from the low tax rates on retained earnings under C-Corp treatment. File Form 8832: C-Corp Election.
Obtain Business Licenses & Permits
To run your business legally, you must obtain applicable licenses and permits. The easiest way to navigate the wide range of federal, state, and local requirements is to search by your business type and locality using the Small Business Administration Business License & Permit look-up tool.
South Dakota Business License
General Business License licensure is not required on the State level in South Dakota.
South Dakota does not have a general business license at the state level, but local licenses are often required.
Ongoing Filings to Maintain Your LLC

In addition to Harbor's help completing the details of my LLC they also helped me set up my first employee on a payroll. I had tried to do this in my own but became overwhelmed by the details and the process. It was not overwhelming to Harbor and they took care of the whole thing.
