South Dakota- Forms for every entity type
- State fee on its own line
- South Dakota agent available
A company formed in another state needs a South Dakota certificate of authority before it does business here, and the Secretary of State charges $750 for it when an LLC or a corporation applies online. Three smaller entity types (nonprofit, limited partnership and LLP) pay $125 each. We prepare the application that fits your entity and file it for $199.
The kind of entity decides almost everything: the form, the fee, the yearly report and the way out. The full guide follows the work in order, the fees page totals the first years and the page on whether the filing is required covers the doing-business test.

The filing can name a commercial registered agent by name; or, with no commercial agent, a noncommercial registered agent by name and address, or the title of an office whose holder will receive service together with that person's business address.
Request the home-state certificate
It goes in with the application.
File and pay

What the certificate means
Think of the certificate as the Secretary of State's record that an out-of-state company may do business in South Dakota. Without one, the company cannot bring a lawsuit in the state, and the Secretary of State becomes its agent for claims arising here. With one, the company can sue in South Dakota courts, keeps its home law for internal matters, and can do only what a South Dakota company of its type could do.
Who needs one
The need arises once a company does business in South Dakota. The statutes name activities that fall outside the term, and for an LLC they add one rule pointing the other way: income-earning property owned in the state counts. A South Dakota business lawyer can say where your own activity falls. The checklist page walks the statute line by line.
The first-year costs
Three payments make up the first year for most LLCs: the application at $750, the home state's certificate, and the annual report at $55. Add them up and the South Dakota side is $805. A corporation's first year with the state looks the same, at $805.
Why the entity type decides so much
Pick the wrong entity and you pay for the wrong form. An LLC states 5 points under SDCL 47-34A-1002. A corporation states the longer list in SDCL 47-1A-1503, including who its officers and directors are. Their annual reports cost the same online but are filed under different chapters, and they leave South Dakota by different filings. Even the test for doing business differs, since an LLC that owns income-producing property is doing business and a corporation that only owns property is not.
What the LLC application asks
The LLC application wants the company name and any alternate name, the home jurisdiction, the principal office, any series information and the initial agent. It comes with the home certificate. The state calls the filing an application for a certificate of authority by a foreign limited liability company, and the LLC form page takes it point by point.
What the corporation application asks
The corporation application adds the date of incorporation, the period of duration, and the names and business addresses of the people who serve as officers and directors. Its home paper is a one-page original certificate of existence. The corporation form page goes through the nine numbered items.
Nonprofits, limited partnerships and LLPs
These entities pay $125 to apply, and a nonprofit pays $10 for its annual report. Tell us the entity type when you order and we match the filing to it.
The years that follow
Later years are routine: the annual report, a statement of change if the agent moves, and an amended certificate if the company changes what it told the state. The state's search tool, used with the business ID, gives each due date.
Checking the name before you pay
The Secretary of State publishes a name availability search, and it is worth running before anything else is ordered. An LLC whose name fails the South Dakota rule files under an alternate name, and a corporation can operate under an assumed name its board adopts.
The home-state certificate
Every application travels with a paper from the company's home state. For an LLC the state asks for a certificate of existence, or a record of similar import, signed by the Secretary of State or other official who keeps the company's public filings in its home state or country. For a corporation it is a one-page original certificate of existence, or a document of similar import, authenticated by the official who keeps the corporate records in the home state or country. What the home state charges for it is up to the home state.
The registered agent
Whatever the entity, the filing includes a registered agent whose address is in South Dakota. Our firm can be the agent, and so can anyone else you name. The registered agent page lists the choices.
Staying authorized
The certificate stays in force while the company keeps up its yearly report, its agent and its fees. The state can revoke it for an unpaid fee, tax or penalty to the Secretary of State left more than sixty days past due; an annual report not delivered within sixty days of its due date; no agent for service of process appointed and kept as South Dakota law requires; and no statement of change delivered within thirty days of a change in the agent's name or address, but only after notice, and the company can cure the problem before the revocation date. The annual report page covers the yearly filing.
If the company waits
The LLC Act sets no daily fine for operating unauthorized. The cost is in what the company cannot do: start a lawsuit in the state until it is authorized. The consequences page walks through every effect.
Ending authority
An LLC ends its certificate with a notice of cancellation, and a corporation instead asks for a certificate of withdrawal ($10). See ending authority.
Where the time goes
The state side is quick: online filings are handled immediately. The slower parts are the ones outside the Secretary of State, namely clearing the name, getting the agent's agreement and waiting on the home state's certificate. We request the home certificate so it arrives with the filing.
Typical starting points
A Minnesota LLC that buys a rental building in Rapid City applies as an LLC, pays $750 and attaches a Minnesota certificate. An Iowa corporation that opens a sales office files the corporation application, lists its officers and directors and pays the same $750. A nonprofit with a regional program asks us which filing fits before it orders. Each starts from the entity table above.
Our part
We handle the drafting, the home-certificate request and the filing. Our rate is $199, and the state's fee is a separate line on your receipt. Prefer to handle the filing alone? The self-filing page shows the route.
