A Guide to Launching an LLC in South Dakota

Starting an LLC in South Dakota is a process that offers flexibility and affordability—here’s a quick guide to get you started.

Step 1: Choose Your LLC Name 

Your South Dakota LLC name must include "Limited Liability Company," "LLC," or "L.L.C." Before falling in love with a name, check availability through the South Dakota Business Entity Search. Your name must be unique and not misleadingly similar to existing businesses. Watch out for restricted words like "bank," "insurance," or "engineering" – these require additional licensing or approval.

Money-Saving Tip: Skip the $25 name reservation fee if you plan to file your LLC formation documents within a few days. Filing your Articles of Organization automatically secures your name.

Step 2: Selecting a Registered Agent

Here's an easy way to save $100-300 annually: serve as your own registered agent. 

You qualify if: 

• You have a physical South Dakota address (no P.O. boxes)
• Can be available during business hours to receive legal documents.
• You are at 18 years of age

While professional registered agent services offer privacy and convenience, being your own agent is a smart way to reduce costs when starting out.

Step 3: File Your Articles of Organization

The real work begins with filing your Articles of Organization with the South Dakota Secretary of State. Save money and time by filing online – you'll pay $150 instead of $165 for mail filing and get immediate processing instead of waiting 3-5 business days.

Here's exactly what you'll need to provide:

• LLC name and principal office address
• Registered agent information
• Whether the LLC is member or manager-managed
• Names and addresses of managers (if manager-managed)
• Duration of the LLC (usually "perpetual")
• Organizer information and signature

Pro tip: File online through the South Dakota Secretary of State Business Registration for instant processing. The online system checks for errors as you go, reducing the chance of rejection and delays. If you're filing by mail, double-check every detail – fixing mistakes later requires additional paperwork and fees.

Your registration will start here. Choose “Domestic LLC” and click “Next.”

Check your name Availability. 

The rest is very simple and straightforward. Fill out the information shown on the side bar.

Review, pay, submit, and wait for approval,

After approval, keep your Articles of Organization safe – you'll need them for opening a business bank account and other important business matters.

Handle Post-Filing Requirements

After your LLC is approved, complete these essential tasks to keep your business compliant and protected:

Get Your Tax Documents in Order

• Apply for an EIN (free through the IRS website)
• Register for sales tax if selling goods/services (state rate is 4.5%)

Understand Your Tax Advantages

• Pay federal taxes (LLCs are typically pass-through entities)
• Collect and remit sales tax if applicable
• Handle any local tax obligations
• File federal self-employment tax if you're actively managing the business
