Top South Dakota Registered Agent Services & Description
A registered agent service is a company that specializes in being a registered agent for a wide variety of businesses across the country, bringing tons of expertise and a healthy dose of reliability to the role.
What’s great is that the personal addresses of home-based entrepreneurs remain private when you hire a professional registered agent service. There are quite a few of these companies out there, and most of them make it quite easy to enlist their services.
Registered agent services usually include some additional features, which vary depending on which company you choose. In general though, you’ll often see these services offer a compliance calendar to help you track your important filing deadlines, and you’ll always receive access to their helpful customer support teams.
Here are the 4 best registered agent services in South Dakota:
1. Northwest Registered Agent

Northwest Registered Agent: Northwest charges $125 per year, and they’re the only major national registered agent service that locally scans every document they receive as your agent. They also have personalized customer support that assigns a dedicated account representative to each client.
Here are some of the other top things to love about Northwest:
- Discount for $100 per year per business if you use them for more than 10 states, or you use them as the registered agent for more than 10 businesses
- Promises never to sell your personal data; stands by their Privacy by Default guarantee
- Offers one year of free registered agent service if you use their LLC formation service, which has a $225 price tag ($125 per year will start on the second year)
One last note: if you do choose to use a business formation package from Northwest, you’ll pay their service fee plus the $150 South Dakota filing fee, creating a total cost of $375 for the first year.
2. Zen Business

Zen Business: Zen Business has a lower $99 rate than Northwest offers, with an extra focus on making the process less stressful and an easier-to-use website. You’ll receive their outstanding customer support, as well as access to helpful software that allows you to track and file your company’s annual reports.
In a nutshell, here are some of the things we love best about Zen Business:

If you use Zen Business to form your business, you’ll pay $39 plus South Dakota’s fee of $150 for the first year. After that, your annual cost will be $119 per year. It’s just $99 per year if you choose registered agent service only.

Incfile: They are one of the most well-known LLC and registered agent services available, with rates that start at just $119 per year. Plus they offer an awesome free LLC formation service if you haven’t created a business yet and would like a free registered agent service in the process.

What Is a South Dakota Registered Agent?
Every business entity in the state of South Dakota is required to have a registered agent. In fact, you will not be allowed to finish the formation process for your company until you designate your registered agent.
In South Dakota, there are three types of registered agents: noncommercial registered agent, commercial registered agent, and office holder of the organization. The only difference between noncommercial and commercial registered agents is that commercial registered agents pay a registration fee of $100 to be listed with the Secretary of State. This makes them easier to find and gives them a better chance of being located by businesses in need of new agents. Meanwhile, an office holder of the organization is the registered agent for a corporation in which one of the corporation’s officers handles this role.
The most important aspect of this role is receiving document deliveries from the state government, then alerting your business of the delivery, before forwarding the documents to you. The role of the registered agent is so important because it establishes a point of contact for your business with the state, so that they have a reliable place to get in touch with an official representative of your company at any time.
The South Dakota Secretary of State provides a comprehensive list of all commercial registered agents currently serving in the state. It might sound overwhelming, but it’s actually a pretty manageable list since it includes only commercial agents. Please note that the list is in alphabetical order—not a ranking—and the State is not endorsing these agents, simply providing their information.
Who Can Be a South Dakota Registered Agent?
A South Dakota registered agent is a person or business entity that has a physical address in the state. You or one of your co-owners can serve as your own registered agent, you can designate a friend or family member for this role, you can hire a lawyer or accountant as your agent, or you can hire an online business services company to provide registered agent service.
No matter who you choose to be your registered agent, they need to be physically present at the address provided to the state during all standard business hours. This person or entity does not need to have any prior experience being a registered agent, but it’s wise to choose a registered agent who is familiar with the serious responsibilities that come with this role.
There is no minimum age requirement for who can be a registered agent in the state of South Dakota. According to the South Dakota Statutes, each company’s registered agent filing must state:
- The name of the represented entity’s commercial registered agent; or…
- If the entity does not have a commercial registered agent:
- The name and address of the entity’s noncommercial registered agent; or…
- The title of an office or other position with the entity if service of process is to be sent to the person holding that office or position, and the address of the business office of that person.
What Does a Registered Agent Do?
A registered agent performs several modest tasks that accumulate into a larger role of significant importance. They are essentially the liaison between your business and the state you are conducting business in.
Legal Matters
First and foremost, a registered agent must act as the designated recipient of any tax or legal documents sent by the state of South Dakota. In the case of legal matters, the registered agent must be physically present to receive hand-delivered service of process (SOP) paperwork regarding legal action being taken against your company. After the handoff, the registered agent then needs to effectively report this delivery to your business, and forward the documents to you.
The registered agent and the business they represent should have a previously agreed-upon order of operations for the intake and delivery of these documents. For example, they should determine whether the documents will be delivered from the registered agent to the business via fax, mail, or email.
Ongoing South Dakota Business Compliance
The registered agent also typically helps ensure that your business remains current and compliant on all state-required ongoing maintenance filings. Each state has its own set of laws regarding which maintenance filings are required, which usually refers to annual reports and/or franchise tax payments. These rules are subject to change at any time, so the registered agent must stay up to date in order to ensure your business remains in good standing with the state, and avoids fines or a business dissolution.
In South Dakota, business entities must file annual reports. The reports for every entity type are due at the end of the same month in which you originally registered your business. There is a fee of $50 for most entities, although nonprofits pay just a $10 fee. If you want to file via a paper form, there is an additional $15 surcharge. Otherwise, you can simply use the state’s online portal (recommended for quicker processing and lower fees). Delinquent reports incur an additional $50 late fee.
Your registered agent should be aware of the schedule and help you file your annual report in order to stay in good standing with the state.
What about small, South Dakota-only registered agent services?
As you’ve probably noticed, the registered agent services we’ve listed here serve businesses across the country. But if you Google “South Dakota Registered Agent,” you’ll probably see results for local services, too. These can be local entrepreneurs with a knack for clerical tasks, offices dedicated to serving businesses in their counties, or statewide companies.
On one hand, using a local service can have its advantages. Some will be cheaper than nationwide firms (but not always!). And each state has its own nuances for business compliance requirements—South Dakota included. A registered agent service that services South Dakota alone will have detailed knowledge about those requirements. Granted, most national services do a good job understanding local requirements. But they probably won’t give you the same “homegrown South Dakota” feeling as a local agent service.
That said, national businesses like Northwest Registered Agent and Zen Business give you streamlined solutions. Let’s say you’re using a local South Dakota-only registered agent service, but it’s time to add locations in North Dakota. You could search for an additional agent that services North Dakota businesses. But that’s going to require a lot of additional paperwork, including new receipts, new automatic payments, more emails…you get the idea. But if you’re using a national service, you can cut down the “new” paperwork and focus on what really matters: growing your business.
Ultimately, the choice is up to you, and there’s no “wrong” answer. The most important thing is that you appoint one so you can run a compliant South Dakota business.
What If I Want to Change My South Dakota Registered Agent?
While the role of the registered agent is vitally important for any American business entity, this role can always be changed, and there are different rules for how to change your agent depending on which state your business operates in.
In South Dakota, all business entities can file a Statement of Change of Registered Office or Registered Agent or Both form. You can file the paper form for a $25 fee, or file it online for just $10.

Need to start a business in South Dakota?
We’ve gone into a lot of detail about registered agents in this guide, but here’s the deal: appointing a registered agent is just one step in the much bigger process of starting a business. If you’re feeling a bit overwhelmed by all that goes into it, don’t panic. We’re here to help.
You can catch the full guide to start a South Dakota LLC, but here’s the fly-by version:
- Choose a business name: Every business in South Dakota needs a name that’s both catchy and gives potential clients a good idea what the business does. The name also needs to be unique—both for legal reasons and so your business stands out from the competition.
- Appoint your registered agent: Whether you elect to use a private registered agent, serve as your own, or you hire a service like the one we’ve listed here, you can’t skip this step. Without a registered agent, you won’t become a legitimate, registered entity.
- File your formation documents: If you’re forming an LLC, you’ll need to file the Articles of Organization; corporations file the Articles of Incorporation. Once you fill it out and file it, this document is what officially forms your business in the state. There is a $150 base filing fee for both corporations and LLCs, but if you file by mail, you’ll pay an additional $15 (the Secretary of State’s incentive to file online).
Beyond that, there are plenty of ongoing maintenance requirements. We won’t go into a ton of detail here, though. Your registered agent will help you keep tabs on most of those, but you can read more here.
