Comprehensive 10-Step Guide to Hire a Registered Agent in South Dakota
From checking the requirement to renewing every year, in the order you will do them.
Step 1 — Confirm you need a South Dakota registered agent
Every South Dakota LLC, corporation and limited partnership must appoint and keep a registered agent under the Model Registered Agents Act, South Dakota Codified Laws chapter 59-11. The agent is named on your formation document and stays on the state's public record.
Step 2 — Decide between being your own agent or hiring a service
You can serve as your own agent if you are a South Dakota resident with a street address or rural route box number in the state and can be there during business hours; most owners hire a service instead to keep that address off the public record and never miss a delivery.
Step 3 — Check the registered office address rule
The registered office must be an actual South Dakota street address or rural route box number, not a P.O. box, and someone must be present to accept delivery there during normal business hours (SDCL 59-11-6).
Step 4 — Choose a South Dakota registered agent service
Compare the annual price, whether mail is scanned the same day it arrives, and whether the state's $10 change filing fee is included before you sign up.
Step 5 — Sign up and provide your entity details
Give your legal entity name, entity type and South Dakota Business ID, if you already have one, so the agent can be listed correctly.
Step 6 — Confirm the agent's appointment is in place
South Dakota conditions a registered agent's appointment on its agreement to serve; a commercial registered agent already holds a Commercial Registered Agent number (CRA#) from its own $100 registration with the Secretary of State, so no separate consent form is needed.
Step 7 — List your registered agent on your formation document
A new LLC names its registered agent and registered office directly on its Articles of Organization, filed with the South Dakota Secretary of State for $150 online or $165 by paper (SDCL 47-34A-203, 212).
Step 8 — File a Statement of Change if you already have an entity
Existing LLCs switch agents by filing the Statement of Change of Registered Office or Registered Agent or Both, SDCL 59-11-11, for $10 online or $25 by paper.
Step 9 — Confirm the change on the public record
Use the Secretary of State's Business Filing Search to confirm your new registered agent is listed before your next Annual Report is due.
Step 10 — Keep your registered agent active every year
South Dakota can administratively dissolve an entity that fails to maintain a registered agent or file its Annual Report (SDCL 47-34A), so renew your agent service before it lapses.

Legal Requirements for a South Dakota Registered Agent
What South Dakota law requires of every registered agent, with the rule and the agency that enforces it.
An actual South Dakota street address
Every South Dakota entity's registered office must be an actual street address or rural route box number in the state, not a P.O. box, under SDCL 59-11-6. Someone must be able to accept delivery there during normal business hours.
Who can serve as your agent
Under South Dakota's Model Registered Agents Act, SDCL ch. 59-11, the agent must be either an individual who resides in South Dakota or a domestic or foreign entity authorized to do business in the state.
Agreement to serve
A registered agent's appointment is not effective until the agent has agreed to serve, under the Model Registered Agents Act, SDCL ch. 59-11. South Dakota has no separate state-filed consent form; a commercial registered agent's agreement is established when it registers with the Secretary of State for a Commercial Registered Agent number, for a $100 fee.
Accepting and forwarding legal notices
South Dakota's Model Registered Agents Act limits the agent's job to accepting service of process, notices and demands addressed to the entity and forwarding them to the entity. The agent has no authority to act on the entity's behalf beyond that.
Reporting a change of agent
A change in registered agent or registered office is reported on the Statement of Change of Registered Office or Registered Agent or Both, SDCL 59-11-11, filed with the South Dakota Secretary of State for $10 online or $25 by paper.
Maintaining an agent at all times
An entity that fails to maintain a valid registered agent, like one that fails to file its Annual Report, risks administrative dissolution by the Secretary of State under SDCL 47-34A.

South Dakota Registered Agent FAQs
Short questions, direct answers.
What is a registered agent in South Dakota?
A registered agent is the person or company named to receive legal papers and official state mail for a South Dakota entity, at an actual street address or rural route box number in the state called the registered office. It is required by the Model Registered Agents Act, South Dakota Codified Laws chapter 59-11.
Do I need a registered agent for my South Dakota LLC or corporation?
Yes. Every South Dakota LLC, corporation and limited partnership must appoint and continuously maintain a registered agent under SDCL ch. 59-11, from the day it files its Articles of Organization.
Can I be my own registered agent in South Dakota?
Yes, if you are a South Dakota resident with a street address or rural route box number in the state where you can accept deliveries during normal business hours. Many owners hire a service instead to keep that address off the public record.
Can I use a P.O. box for my South Dakota registered agent address?
No. SDCL 59-11-6 requires the registered office to be an actual street address or rural route box number; a P.O. box does not qualify.
How much does a South Dakota registered agent cost?
LLC Register charges $99 a year. Commercial registered agent services generally range from about $99 to $249 a year, based on published pricing checked 9/30/2026.
How do I change my registered agent in South Dakota?
File the Statement of Change of Registered Office or Registered Agent or Both, SDCL 59-11-11, with the South Dakota Secretary of State for $10 online or $25 by paper.
What happens if I don't have a registered agent in South Dakota?
The Secretary of State can administratively dissolve the entity under SDCL 47-34A for failing to maintain a registered agent, the same process used against entities that don't file their Annual Report.
Does my registered agent need to consent to serve?
Yes. Under the Model Registered Agents Act, SDCL ch. 59-11, an appointment is not effective until the registered agent has agreed to serve. South Dakota has no separate state-filed consent form; a commercial registered agent's agreement is established when it registers with the Secretary of State for a Commercial Registered Agent number.
Can a family member or friend be my South Dakota registered agent?
Yes, as long as they reside in South Dakota, have a street address or rural route box number in the state, are available during business hours, and agree to serve.
Can an out-of-state company be my South Dakota registered agent?
Only if that company is itself authorized to do business in South Dakota and maintains a South Dakota address; an unregistered out-of-state entity cannot serve as agent.
How fast will I know if my registered agent receives a lawsuit?
South Dakota's Model Registered Agents Act requires a registered agent to forward process, notices and demands to the entity; LLC Register scans and emails it to you the same day we receive it.
Is my registered agent's address public record in South Dakota?
Yes. The registered agent's name and registered office address are part of the entity's public filing with the South Dakota Secretary of State and can be looked up through the state's Business Filing Search.
Can my registered agent resign?
Yes. A registered agent can file a Statement of Resignation of Registered Agent with the Secretary of State at no filing fee; the resignation takes effect on the 31st day after filing or upon appointment of a new agent, whichever occurs first.
Do I need to update my registered agent on my annual South Dakota filing?
Yes. The Annual Report, due the first day of your LLC's anniversary month to the Secretary of State, must show your current registered agent and registered office (SDCL 47-34A-211; 59-11-24, 24.1).
Does every South Dakota entity type need a registered agent?
Yes, for every filing entity: LLCs, corporations, limited partnerships and most other entities registered with the South Dakota Secretary of State must appoint one under SDCL ch. 59-11.
Does a foreign LLC formed in another state need a registered agent to do business in South Dakota?
Yes. A foreign LLC must appoint a South Dakota registered agent with an actual street address before the Secretary of State will issue its Certificate of Authority, filed under SDCL ch. 47-34A for $750 online ($765 by paper) — the same registered agent rule that applies to a domestic LLC.
Does each series in a South Dakota series LLC need its own registered agent?
No. South Dakota recognizes series LLCs through a Master Series Articles of Organization (SDCL ch. 47-34A; $200 domestic, $800 for a foreign master series), and the registered agent named on that master filing covers every series registered beneath it — there is no separate per-series agent appointment.
Does a South Dakota limited liability partnership (LLP) need a registered agent?
Yes. An LLP maintains a registered agent the same as an LLC, under SDCL ch. 59-11, named on its $125 Statement of Qualification and confirmed on its Annual Report ($55 online, $70 paper).
How much notice does a resigning registered agent have to give before stepping down?
A resigning agent must mail a copy of its Statement of Resignation of Registered Agent to the entity at its last known address on or before the day it files the resignation with the Secretary of State; the resignation itself isn't effective until the entity names a replacement or the 31st day after filing, whichever comes first.
What happens if someone tries to sue my LLC and my registered agent can't be found?
South Dakota's Model Registered Agents Act (SDCL ch. 59-11) allows service on the Secretary of State once reasonably diligent attempts to serve your registered agent at the registered office have failed; the Secretary of State then forwards the papers to your entity's last known address.
Does a South Dakota nonprofit corporation need a registered agent?
Yes. A nonprofit corporation must appoint and maintain a registered agent under SDCL ch. 59-11, the same requirement that applies to for-profit entities, confirming it on its $30 Articles of Incorporation and its $10 Annual Report.
Does a South Dakota limited partnership need a registered agent?
Yes. An LP maintains a registered agent just like an LLC, named on its $125 Certificate of Limited Partnership or, for an out-of-state LP, its $125 foreign registration.
How do I look up a company's registered agent in South Dakota?
Search the Secretary of State's free Business Information Search at sdsos.gov by entity name or filing number; the result shows the entity's current registered agent name and registered office address.
If I convert my South Dakota LLC into a different entity type, do I need a separate registered agent filing?
No, not if you're keeping the same agent. The conversion filing itself carries the registered agent forward to the new entity type; a separate $10 Statement of Change is only needed if you're also switching to a new agent.
Can my registered agent service change its own name or address without switching to a new agent?
Yes. Under SDCL ch. 59-11, a registered agent can update its own name or address directly with the Secretary of State without the entity filing anything — it keeps serving your entity under the new information.
Can one person or company serve as the registered agent for more than one South Dakota LLC?
Yes. A single individual or registered agent service can be named on any number of South Dakota entities; a company doing this commercially typically files a $100 Commercial Registered Agent Registration so it can be referenced on other entities' filings without re-listing its full address each time.
Are registered agent fees tax-deductible?
Yes. The IRS treats an annual registered agent fee as an ordinary and necessary business expense, deductible in the year you pay it.
Can my attorney serve as my South Dakota registered agent?
Yes, as long as your attorney has a street address in South Dakota where they can accept deliveries during business hours — the same eligibility rule under SDCL ch. 59-11 that applies to anyone else; no bar membership or special licensing is required.
Is there a difference between a "registered agent" and an "agent for service of process"?
No. South Dakota's Model Registered Agents Act (SDCL ch. 59-11) uses the term "registered agent," and "agent for service of process" describes the same role in plain language.
What happens if mail sent to my registered agent's address is returned as undeliverable?
The Secretary of State treats that the same as having no valid registered agent on file, which can lead to the same administrative dissolution process under SDCL 47-34A that applies to any entity without a current agent.
Do I have to name my registered agent on my Articles of Organization, or can I add one later?
You have to name one upfront. South Dakota's Articles of Organization require the registered agent's name and street address before the Secretary of State will file it — you can't leave it blank and add an agent afterward.
What is the difference between my registered office and my principal place of business?
Your registered office is specifically where your registered agent accepts legal mail and must be an actual South Dakota street address; your principal office is wherever you actually run the business and doesn't have to be in South Dakota at all.
Can a UPS Store or other commercial mail-receiving service be my registered office address?
No. SDCL 59-11-6 requires an actual street address where the agent can personally accept delivery, and a commercial mail-receiving service or mailbox rental doesn't meet that rule any more than a P.O. box does.
Is my registered agent's phone number or email made public?
No. South Dakota's public filings list only your registered agent's name and street address; no phone number or email address is required or published.
Do South Dakota nonprofit corporations have to confirm their registered agent on an annual report?
Yes. Nonprofit corporations file a $10 Annual Report with the Secretary of State every year, and it must show the corporation's current registered agent and registered office.
Can my registered agent also be an officer or manager of my company?
Yes. Nothing in SDCL ch. 59-11 prevents an owner, manager or officer from also serving as the entity's registered agent, as long as they meet the street-address and availability requirements.
Does South Dakota require registered agents to be licensed or bonded?
No. There is no state license or bond requirement for an individual registered agent; a company that wants to act commercially as registered agent for other entities instead files a $100 Commercial Registered Agent Registration with the Secretary of State so its name can be referenced on their filings.
Can I serve as my own registered agent if I live out of state but own property in South Dakota?
No. SDCL ch. 59-11 requires an individual registered agent to maintain an actual street address in South Dakota where they personally accept deliveries; owning South Dakota real estate doesn't meet that requirement if you live elsewhere.
Does my registered agent have authority to sign contracts or make decisions for my LLC?
No. A registered agent's role under SDCL ch. 59-11 is limited to receiving and forwarding legal notices and process addressed to the entity — it has no authority to sign contracts or act on the entity's behalf.
Can the same South Dakota address serve as both my registered office and my principal place of business?
Yes. Nothing requires the two to be different — a small business commonly uses one South Dakota street address for both, as long as it meets the registered office's physical-address and business-hours-availability rule.
