Domestic LLC Formation Filing Requirements in South Dakota

At a glance

Requirements one by one

Governing law and filing record

South Dakota forms an ordinary domestic LLC under Chapter 47-34A by filing Articles of Organization with the Secretary of State under § 47-34A-203.

Organizer and signature

The articles list every organizer's name and address. Under § 47-34A-205, a preformation filing is signed by a person organizing the company and states the signer's name and capacity beside the signature. An attorney-in-fact may sign; the company retains the power of attorney rather than filing it.

Required entity and purpose terms

The name must be distinguishable and use “limited liability company,” “limited company,” “L.L.C.,” “LLC,” “L.C.,” or “LC” under § 47-34A-105. The purpose field is optional. The articles state duration only if the company is not perpetual.

Addresses and service fields

The articles give the initial designated office's street and mailing addresses. They also include the § 59-11-6 registered-agent information: a commercial agent, a named noncommercial agent with South Dakota address, or an internal office/position and business-office address. The paper form displays the first two routes and optional email fields.

Management and owner disclosure

The articles choose member or manager management. A manager-managed company lists every initial manager and address. A member-managed company does not list its members under the statute or current paper form.

Section 47-34A-203 also requires the articles to state whether one or more members assume liability for company debts. The current paper form has no dedicated field for that required election. Its beneficial-owner table is separate and expressly optional. Confirm whether the current online workflow collects the liability election or whether it should be added in the other- provisions section or a custom filing.

Optional and restricted provisions

The articles may include operating-agreement provisions or other lawful matter. They cannot vary the nonwaivable rules in § 47-34A-103(b). For other conflicts, the agreement controls insiders, while the articles control outsiders who reasonably rely on them to their detriment.

Filing method, fee, and attachments

Under § 47-34A-212, the base filing fee is $150. Paper filing costs $165, including the $15 paper-filing fee. Optional expedited handling is $50.

An ordinary filing has no universal attachment. Because the current paper form omits the statutory member-liability election, a filer using paper should confirm whether to add that statement in Article VIII or through another accepted custom route.

Formation and effective date

Under § 47-34A-206, the articles take effect at filing, at a stated later time that day, or at a delayed date and time no more than 90 days after filing. A delayed date without a time takes effect at close of business.

What trips people up

The current paper form does not display the member-liability election required by § 47-34A-203(a)(7). The optional beneficial-owner table does not substitute for that statutory statement.

South Dakota publicly identifies every organizer and, for a manager-managed company, every initial manager. It does not require the initial members' names for a member-managed company.

There is no formation publication or one-time initial report. Under § 59-11-25, the first annual report is due before February 1 of the year after formation. The current fee is $55 online or $70 on paper.

Common questions

Is the purpose clause required?

No. The current paper form labels it optional, and § 47-34A-203 does not include purpose in the mandatory list.

Must a member-managed LLC list its members?

No. The articles state the management structure but list initial managers only when manager-managed.

Can the articles take effect later?

Yes. A delayed date and time may be up to 90 days after filing.
