Full transcript

0:00 The short answer

Dan The 5 best registered agents in South Dakota in 2026 are Mainstay Filing, Northwest Registered Agent, SD Registered Agent.org, Bizee, and South Dakota Registered Agent.co.

Maya This is The Business Formation Podcast. South Dakota. What should I know before I choose?

Dan A change of agent is $10 online, but $25 on paper. And South Dakota's LLC annual report lists your agent, so the record has to stay current.

0:31 What South Dakota requires

Maya What does the law say?

Dan Chapter 59-11, the Model Registered Agents Act, says every entity needs a registered agent. South Dakota splits them into noncommercial and commercial.

Maya What's the difference?

Dan A noncommercial agent is an individual who lives in South Dakota, or a business entity registered in the state. A commercial agent is an organization that has paid a registration fee and registered with the Secretary of State.

Maya Can an officer of the company just do it?

Dan Not for an LLC. The state's FAQ says the office holder option doesn't apply to LLCs.

Maya I'm Maya, by the way, here with Dan.

Dan Thanks, Maya. Now the five.

1:14 Mainstay Filing

Maya First?

Dan Mainstay Filing, $149 a year, and the same $149 when it renews.

Maya What do I get?

Dan Its South Dakota address on the public record instead of yours. Papers served on your company are scanned and uploaded the same business day, no fee. And the first three government mailings each year are scanned free.

Maya If I have an agent now?

Dan Mainstay files the change. The $10 state fee goes through at cost.

Maya The catch?

Dan Two agents on this list are $99, so the flat price isn't the lowest.

1:50 Northwest Registered Agent

Maya Second?

Dan Northwest Registered Agent, $125 a year. Its page says the price hasn't gone up in 20 years. Up to 10 pieces of business mail a year are scanned free.

Maya The catch?

Dan Signup auto-enrolls you in its annual report filing service, which is $100 plus state fees per filing, until you cancel it.

Maya What's the state fee for the report?

Dan $55 online. So that service adds $100 on top of the state's price.

2:20 SD Registered Agent.org

Maya Third?

Dan SD Registered Agent.org, $99 a year, same at renewal. A South Dakota address, professional document handling, and compliance support.

Maya And to switch?

Dan Just the $10 state fee.

Maya Catch?

Dan Annual report filing is a separate service.

Maya And against number one?

Dan $50 less a year, or $150 over three years.

2:47 Bizee

Maya Four?

Dan Bizee, formerly Incfile. Free the first year with any formation package, then $149 a year.

Maya The fine print?

Dan The free year needs a formation order, and the $149 renewal is automatic.

Maya If I'm formed already?

Dan Then it starts at $149. Two years is $298.

3:12 South Dakota Registered Agent.co

Maya And five?

Dan South Dakota Registered Agent.co, a flat $99 a year. The registered agent address, same-day scanning of legal documents, and reminders before your annual report deadline.

Maya Different from number three?

Dan On price and on the catch, no. Annual report filing is a separate service.

3:34 Naming the agent at formation

Maya Where does the agent go on the formation filing?

Dan Article III of the Articles of Organization. A noncommercial agent needs an actual street address in South Dakota, plus a mailing address. A commercial agent is listed by name and its commercial registered agent number.

Maya What does it cost?

Dan $150 online, or $165 on paper.

Maya What counts as an address?

Dan An actual street address or a rural route box number in the state, and a mailing address in the state if it's different.

Maya And the agent's consent?

Dan The statute says appointing an agent is your affirmation that the agent consented. You don't file proof of it.

4:21 Changing the agent

Maya How do I change it?

Dan With a Statement of Change of Registered Office or Registered Agent, signed on behalf of the entity.

Maya What does it cost?

Dan $10 at Business Services Online. The state accepts Visa, MasterCard, Discover and American Express there.

Maya And on paper?

Dan Paper adds a $15 filing fee. The paper form itself prints $25.

Maya Do members have to approve?

Dan No. The statute says the interest holders or governors need not approve it.

Maya When is it effective?

Dan On filing.

4:54 What the agent has to do

Maya What are the agent's actual duties?

Dan South Dakota lists only a few. Forward any process, notice or demand to the entity at the address it most recently supplied.

Maya What else?

Dan Give the notices the chapter requires. And keep its own information current.

Maya And what does the agent receive?

Dan Service of any process, notice or demand the law requires or permits to be served on the entity.

Maya So a good agent is mostly about forwarding fast.

Dan Exactly, and about the address being right.

5:30 If the agent resigns

Maya What if my agent quits?

Dan It files a statement of resignation. There's no charge, and the form says no filing fee.

Maya When does it take effect?

Dan The earlier of the 31st day after it's filed, or when you appoint a new agent.

Maya Does it tell me?

Dan The agent must promptly give your LLC notice of the date it filed.

Maya Does good standing matter?

Dan It doesn't. An agent may resign whether or not the entity is in good standing.

5:56 When there's no agent

Maya And if there's no agent to serve?

Dan The entity may be served by registered or certified mail, return receipt requested, addressed to its governors by name at the principal office.

Maya Where do the names come from?

Dan The most recent annual report.

Maya When is it complete?

Dan At the earliest of receipt, the date on the return receipt, or five days after it's mailed.

Maya And if that fails?

Dan Someone can hand a copy to the manager, clerk or person in charge of a regular place of business.

Maya Any effect on the LLC itself?

Dan The Secretary of State's FAQ says failure to keep a valid agent on file can lead to administrative dissolution.

6:35 The annual report

Maya What does South Dakota ask each year?

Dan An annual report, $55 online or $70 on paper.

Maya When is it due?

Dan The first day of your anniversary month.

Maya And late?

Dan A $55 late fee once it's two months past due.

Maya Does it mention the agent?

Dan Yes, the report lists the registered agent. That's another reason to update the agent first.

Maya Anything changing?

Dan From January 1, 2027, an entity may choose January 31 each year instead.

7:06 Doing it yourself

Maya Can I be my own agent in South Dakota?

Dan If you live in South Dakota, as an individual noncommercial agent, yes. The state's FAQ says the agent needs both a physical and a mailing address in the state.

Maya What's the downside?

Dan Your address is public, and so are the lawsuits that arrive there.

Maya Is there an hours rule?

Dan Not in the chapter or the FAQ.

Maya So what's the real cost?

Dan Being reachable, and never missing a forward.

7:37 Picking one

Maya How would a Sioux Falls or Rapid City owner pick?

Dan Three questions. Does the price hold at renewal, is the address a real South Dakota one, and who files the change.

Maya Your answer?

Dan Mainstay Filing. Our pick for South Dakota, at $149 a year.

7:55 The five in a row

Maya All five again?

Dan One, Mainstay Filing: $149, same at renewal. Two, Northwest: $125, with the report service to cancel. Three, SD Registered Agent.org: $99 flat. Four, Bizee: free the first year with a formation order, then $149. Five, South Dakota Registered Agent.co: $99 flat.
