1Name Your South Dakota LLC

The first listing requirement is ensuring your business name is unique. It must be distinguishable from other entities registered with the Secretary of State. You must also include a designator like "LLC" or "Limited Liability Company" to comply with state statutes.

2Assign a Registered Agent

Every South Dakota LLC must appoint a Registered Agent. This individual or business entity agrees to accept legal documents (Service of Process) on behalf of your company. They must have a physical street address in South Dakota (not a P.O. Box) and be available during regular business hours.

3File Articles of Organization

To officially create your entity, you must file the Articles of Organization with the state. The filing fee is $150. This fee is non-refundable. Most entrepreneurs choose to file online for faster approval, which typically takes Immediate (Online).

4Get Your EIN & Bank Account

Once your LLC is approved, apply for an EIN (Employer Identification Number) from the IRS. This nine-digit number is required to open a business bank account, hire employees, and file taxes. Keeping your business finances separate from personal accounts is critical for maintaining your liability protection.

Common Questions in South Dakota

How much does it cost to start an LLC in South Dakota?
The state filing fee for a South Dakota LLC is $150, paid once to the Secretary of State. If you use a formation service, you pay this state fee plus the service's own charge.
How long does it take to get an LLC in South Dakota?
Online filings in South Dakota are typically approved immediately, though it varies with filing volume. Expedited processing (same day) is available for an extra $50.
Does South Dakota require an Annual Report?
Yes. South Dakota LLCs must file an annual report with the Secretary of State. The fee is $55, due by the end of your LLC's anniversary month. Missing it can lead to administrative dissolution.
Do I need to file a BOI report with FinCEN for my LLC?
No — not if your LLC was formed in the United States. FinCEN's interim final rule of March 2025, made permanent by a final rule on August 14, 2026, exempts all U.S.-created companies, including LLCs, and their U.S. owners from Beneficial Ownership Information reporting under the Corporate Transparency Act. Only entities formed under foreign law that register to do business in a U.S. state must still report. Be wary of mailers or emails demanding a BOI filing fee.
Can I be my own Registered Agent?
Yes. You can serve as your own registered agent in every state as long as you have a physical street address in that state and are available there during normal business hours to accept legal papers (service of process). The trade-off is privacy: that address goes on the public state record. Many owners hire a registered agent service to keep their home address off public filings.
