Who can serve

A noncommercial registered agent can be an individual who resides in South Dakota or a business entity registered there. A commercial registered agent can also serve after registering with the Secretary of State. The South Dakota office-holder option listed for some entities does not apply to LLCs.

What the agent does

The agent receives lawsuits, official notices, and state communications. The agent does not automatically:

Form the LLC
Write an operating agreement
Apply for an EIN
Register South Dakota tax licenses
File tax returns
Obtain local or professional licenses

Owner versus paid service

Serving as your own agent can avoid a recurring service charge, but it requires a South Dakota address and reliable availability. A commercial agent can provide an address, mail handling, and reminders, but compare renewal price, forwarding rules, cancellation terms, and add-on charges.
