Timeline. The standard processing time for documents with the Secretary of State is between two to three weeks. For an additional fee of $50, expedited services move processing time up to between five to eight business days.

Naming requirements. LLC naming requirements can be confusing. However, the easiest way to ensure that your LLC name will be approved is to make it distinguishable from other LLCs and to include specific words required of LLCs. You may opt to have a preferred name checked for availability before filing your LLC formation documents with the Secretary of State.

Formation requirements. To form an LLC, a registrant must first file Articles of Organization with the Secretary of State.

An LLC with more than one member is also strongly advised to have a limited liability company operating agreement among its members.

Should your LLC offer professional services, you may have to obtain certain licenses and permits from the state’s professional licensing boards.



Starting an LLC in South Dakota

Before you begin the registration process for an LLC in South Dakota, it’s important to know what an LLC is and whether or not it is a viable business structure for your company, so be certain to read up on the definition and benefits of an LLC.

These steps will guide you through the LLC registration process with the South Dakota Secretary of State:

1. Decide on a name for your business. You can choose any name for your LLC as long as it ends with “Limited Liability Company,” “Limited Company” or any variation of its abbreviation—e.g., L.L.C., LLC, L.C. or LC.

Names may be reserved for up to 120 day by filing a name reservation application with the Secretary of State. This may be done by mail or online and must be filed in duplicate. All requests must be accompanied by the $25 filing fee. Be sure to include the name to be reserved and the name, title, address and dated signature of the applicant.

Prior to filing a name reservation application, you may check the availability of the preferred name on the Secretary of State website.

2. Assign an agent for service of process. This is also referred to as the resident agent.  

3. Get an Employer Identification Number (EIN) from the IRS. If there are two or more members in your LLC, your company will need to obtain an EIN from the IRS, for tax purposes.

4. Create an operating agreement. Although a South Dakota LLC is not required to have a limited liability company operating agreement, it is wise to have one in place with other members should your LLC have more than one member. The State of South Dakota recognizes limited liability company operating agreements as governing documents.

5. Familiarize yourself with the LLC’s continuing legal obligations, specifically annual reports. These are due every year in the anniversary month of the formation of the LLC. There is a $50 filing fee that must be paid upon filing the report with the Secretary of State. All reports may be done online or by mail. Failure to turn in a report will render the LLC delinquent.

Make sure your LLC, should it offer professional services, meets South Dakota state legal requirements.

Additional continuing legal obligations may vary with each state. These could be, but are not limited to, state taxes, annual or biennial reports and so on.
