What is a registered agent for a South Dakota LLC?

A registered agent is the person or business that accepts lawsuits and official notices for your LLC. South Dakota requires your Articles of Organization to name one: either a commercial registered agent listed with the Secretary of State, or a noncommercial agent (an individual or a business) with an actual street address or rural route box number in South Dakota. South Dakota law also allows the title of an office or position within your LLC, with that person's business address, in place of a named agent. The agent's information also goes on each annual report.

What happens if my South Dakota LLC doesn't have a registered agent?

South Dakota's LLC Act does not list a missing agent as a ground for administrative dissolution; the grounds are unpaid fees, taxes or penalties, or an annual report more than 60 days late. Instead, South Dakota law says that if your LLC no longer has a registered agent, or the agent cannot be served with reasonable diligence, the LLC can be served by registered or certified mail addressed to its governors at its principal office. That makes it easier for a lawsuit to slip past you, so you could face a default judgment without knowing you were sued. If your agent resigns, the resignation takes effect on the 31st day after it is filed, or earlier if you appoint a new agent.

How much does a registered agent cost in South Dakota?

Serving as your own registered agent costs nothing if you can accept papers at a South Dakota street address or rural route box number. A professional registered agent service charges its own annual fee, which varies by provider. Among the national services we compare, Northwest charges $125 a year for registered agent service (a year is included when you form a new LLC with its paid package, $39 plus your state's filing fee), and LegalZoom charges $249 a year and does not include the service in any formation plan. Changing your agent later costs $10 online.

Does using a registered agent protect my privacy in South Dakota?

Yes. The registered agent information on your Articles of Organization and annual reports appears with your LLC's record in the Secretary of State's public business search. If you are your own agent, that is your South Dakota address. A commercial registered agent is identified by name only, with its address already on file with the Secretary of State. It does not hide everything: other filings for your LLC can still show names and addresses, so check what each form asks for before you file.

Can I change my South Dakota LLC's registered agent?

Yes. To change your South Dakota registered agent, file a Statement of Change of Registered Agent and/or Address with the South Dakota Secretary of State. The fee is $10, you can file it online, and if you print it and mail it instead the Secretary of State adds a $15 paper processing fee. The new agent does not sign: South Dakota law treats naming the agent as your LLC's statement that the agent has agreed, so get the agent's approval first. The change takes effect when it is filed.

Everything you need to know about registered agent rules, costs, and options to keep your South Dakota LLC compliant in 2026.

South Dakota requires every LLC to name a registered agent in the Articles of Organization it files to form. Hiring a paid service is optional: in most states the LLC's owner, or another individual who qualifies, may serve as its registered agent, and the rules below set out who qualifies in South Dakota. See the rules below.

Best Registered Agent Services for South Dakota LLCs (2026)

Affiliate disclosure: Northwest Registered Agent, Bizee, ZenBusiness and LegalZoom pay us a commission if you sign up through our link, at no extra cost to you. We list only the registered agent services we have an affiliate relationship with, so this is not a survey of the whole market.

This table is not scored. The four are listed cheapest annual renewal first, and the rows below it say which one fits which situation. The scored ranking, and the formula behind it, is on the formation services review, which orders them on three-year cost, BBB rating and Trustpilot score.

Service	With formation, year 1	Annual renewal	BBB	Trustpilot	Privacy
Northwest Registered Agent	Included with $39 formation	$125/yr	A	4.1/5 (297)	Says it does not sell your information; runs its own servers
Bizee	Free year one (some visitors are being shown shorter free periods, so confirm at checkout)	$149/yr	C (unaccredited)	4.8/5 (26,100+)	No data-sharing commitment
ZenBusiness	$99, not included in any plan	$199/yr	A	4.8/5 (32,500+)	Partial
LegalZoom	Not included, $249 extra	$249/yr	A+	4.6/5 (32,900+)	Partial

Note: Bizee holds a C rating from the BBB and is not accredited. BBB's profile carries a live alert describing a pattern of complaints about unexpected charges, difficulty canceling and filing delays, and Bizee has posted a response to it. We flag this so you can make an informed choice.

Prices are each provider's standard published rates; year-one pricing applies when you form your LLC through the same service. BBB and Trustpilot figures as recorded September 15, 2026, not re-checked since, and both sources update continuously. These are the dates the figures were last written to our dataset, which is the most we can show: they are not verification dates.

Which Registered Agent Is Best for Your South Dakota LLC?

You're forming a new LLC and want phone, email and chat support

Our pick: ZenBusiness

A $0 Starter formation plan, backed by an A from the BBB and a 4.8/5 Trustpilot score. Registered agent is not included in any plan: it is $99 for the first year when you form with them, then $199/yr.

Your LLC already exists and you just need an agent

Our pick: Northwest Registered Agent

A flat $125/yr for registered agent service, the lowest renewal of the services listed here, and a privacy policy that says it does not sell your information. Registered agent customers are enrolled by default in Northwest's report filing service, which charges your saved payment method $100 plus state fees each time it files for you and which you can cancel.

You want year one free and the cheaper renewal after it

Our pick: Bizee

Registered agent is free for year one on every Bizee plan and renews at $149/yr, $50/yr less than ZenBusiness. Northwest renews lower still at $125/yr, but its first year comes inside a paid $39 formation package rather than free. Tradeoff: a C rating from the BBB, which cites a pattern of complaints about charges and cancellation, so read every auto-renewal term.

Complex legal needs alongside your filing

Our pick: LegalZoom

The only one of the services listed here with attorney consultations, which come with LegalZoom's $299 formation plan (and in one version of its plans its $249 plan) for 30 days and then cost $49 or $99 a month until you cancel, depending on the version. Also the most expensive registered agent listed here at $249/yr, which is never included in their plans.

This guide is general information, not legal or tax advice, and reading it does not create an attorney-client relationship. It reports what each state publishes about filing deadlines, fees, and the consequences of missing them, with the sources this page cites. It cannot tell you what your own company owes: the date turns on when and where you formed, states change these rules between our reviews, and in several states an entity-level tax falls due in a year when no report does. Confirm your own dates with the filing office named on this page before you rely on one here, because missing a deadline can cost the company its good standing or, in many states, its existence.
