What the state charges, and the two ways to file
The state filing fee for a foreign LLC's certificate of authority is $750 when you file electronically through Business Services Online, set by SDCL 47-34A-212(a). Filing on paper adds the Secretary of State's $15 paper filing fee, which brings the paper total to $765. A series LLC pays more under § 47-34A-212(c).
With a fee of that size, it is worth confirming that your LLC really is transacting business in the state before you file. The next section walks through the statute's test.
The Secretary of State's FAQ says online filings are processed immediately, while new paper filings average one to three business days.
Does your LLC need a certificate of authority?
SDCL 47-34A-1002(a) is blunt: until the Secretary of State grants a certificate of authority, a foreign LLC cannot do business in South Dakota. The statute lists what does not amount to transacting business (§ 47-34A-1003(a)), and that list is a good test.
Outside the rule are handling litigation, gatherings of members or managers, accounts at financial institutions, sales via independent contractors, orders that require acceptance elsewhere, borrowing, securing and collecting debts, a lone deal that closes inside thirty days without belonging to a run of similar ones, and interstate commerce.
Then comes the catch in subsection (b). If the LLC owns income-producing real property in South Dakota, or tangible personal property the list does not exclude, that ownership constitutes transacting business. A company with a rental building or a leased fleet here has to qualify even if it never opens an office. Subsection (c) adds that these rules leave open what counts for service, tax or regulatory purposes under other laws.
Filing details and the home-state certificate
The application is filed with the Secretary of State in Pierre, online or on paper. It asks for:
- the LLC's name, and an alternate name if the real one does not meet the South Dakota naming statute;
- the state or country where it was formed;
- the street and mailing addresses of the principal office, and of any office its home law requires;
- series information, where it applies;
- the registered agent's name and its South Dakota street and mailing addresses.
An original, one-page Certificate of Existence has to travel with the application, signed by your home-state Secretary of State or whichever official has custody of the company's organizational records (§ 47-34A-1002(c)). The South Dakota materials give no age limit for it. Because the home-state office issues the certificate, order it and have it ready before you file.
Names and the alternate-name option
South Dakota's LLC statute expects the name to carry a designator, either spelled out or abbreviated (for instance LLC or L.C.). When a foreign LLC's name falls short, § 47-34A-1005 withholds the certificate until the company picks an alternate name to use for business here. The alternate name goes in the first item of the application, next to your real name, and from then on it is the name you operate under in South Dakota.
Registered agent requirements
South Dakota requires a registered agent who lives in the state, with both a physical address and a mailing address in South Dakota. The Secretary of State accepts two kinds. A noncommercial agent can be an individual resident of South Dakota or a business entity registered in the state. A commercial registered agent is an organization that has paid the state's registration fee and carries a commercial agent number, which goes on the form.
Naming an agent is a statement that the agent has agreed to serve (SDCL 59-11-6). The application asks you to choose between the two types and fill in the matching details.
What not registering costs
The consequences are in § 47-34A-1008, and a fine is not among them. An LLC doing business here without a certificate is barred from starting or pursuing a case in South Dakota courts. Nothing it signed becomes void, and being sued remains something it can fight. Members and managers do not take on personal liability merely because the certificate was never obtained.
Meanwhile the Secretary of State is deemed the company's agent for receiving process in disputes that stem from its South Dakota activity, which means a suit could be served there. Section 47-34A-1009 also lets the Attorney General seek an injunction to stop the LLC from transacting business in violation of the article. The home state's law continues to govern internal affairs and members' liability (§ 47-34A-1001).
After you are authorized
Once authorized, the LLC owes South Dakota an annual report on the first day of the month matching its original filing date. Filed June 11, 2026? The first report is due June 1, 2027. Expect $55 if you file online and $70 by paper. The report asks whether the entity owns agricultural land and about foreign beneficial owners. A 2026 amendment effective January 1, 2027 gives entities in good standing the choice of filing in the anniversary month or by January 31 of each year.
A report is delinquent if it has not been filed two months after the due date, and a $55 late fee applies. The certificate may be revoked if the report or a fee is more than sixty days overdue or the LLC has no agent, with at least 60 days' notice and a chance to cure. South Dakota does not reinstate foreign entities; a revoked company must apply again for a new certificate of authority.
To leave the state, file the Notice of Cancellation of Certificate of Authority, $10. Other South Dakota tax and license registrations may also apply to your business.
What Mainstay takes care of
Hand us your company's information and the Certificate of Existence from home, and we put together the application and send it in. The South Dakota registered agent is part of the order with no charge in year one, then $149 each year. Should a summons or other legal paper reach that agent, we scan it and upload it for you within the same business day, and nothing is added to the bill.
Your total is $949 today: $199 for our work added to the state's $750. The price buys the filing and the first year of agent service, and leaves out your annual reports and tax returns. Mainstay files; it does not practice law.
An out-of-state corporation pays the same fee and the same $949 today.
Frequently asked questions
How much does a South Dakota certificate of authority cost?
The state charges $750 online, or $765 when you file on paper. Our checkout adds $199 to the online fee, so the total today is $949.
Does South Dakota want a good standing certificate?
It wants a one-page original Certificate of Existence from your home state's filing office. No age limit appears in the statute or on the form.
Is owning rental property in South Dakota enough to trigger registration?
Yes. Under the statute, holding rental real estate or similar revenue-producing assets here is transacting business, subject to the exclusions in its list.
Who can serve as registered agent?
A South Dakota resident individual or a business entity registered in the state, or a commercial registered agent. The agent needs a physical address plus a mailing address inside South Dakota.
What if I cannot use my LLC's name in South Dakota?
You adopt an alternate name and put it on the application. The certificate cannot be issued until the name complies with the state's naming rules.
When is the annual report due, and what does it cost?
On the 1st of the anniversary month of your filing, for $55 online or $70 on paper. A report two months late is delinquent and adds a $55 fee.
Can a revoked certificate be reinstated?
No. According to the state, a foreign entity is never reinstated; it files for a brand-new Certificate of Authority.
Does South Dakota law take over my LLC's internal rules once I register?
No. Your home jurisdiction's law keeps governing how the company runs internally and what its owners and managers are liable for. The certificate only lets the company do business in South Dakota.

Starting a brand-new South Dakota company instead?
Foreign qualification is for a company that already exists somewhere else. A new company is formed rather than registered, and that is a different order. See how forming in South Dakota works →Need only the agent for a company you already registered here? South Dakota registered agent service →
