South Dakota registered agent — frequently asked questions
Do I need a registered agent for my South Dakota LLC?
Yes. South Dakota requires every LLC and corporation to name a registered agent on its formation documents and to keep one continuously. The agent accepts service of process (lawsuits) and official notices from the South Dakota Secretary of State, Division of Business Services on the company's behalf.
Can I be my own registered agent in South Dakota?
You can if you are an adult with a physical street address in South Dakota (not a PO box) and you are available there during normal business hours. Many owners prefer a service so their home address stays off the public record, nothing is missed while they travel, and the address does not have to change when they move.
How much does a registered agent cost in South Dakota?
Incofile's South Dakota registered agent service is $119 per year, and the first year is included free when you form your company with any Incofile package. Acting as your own agent costs nothing in fees but puts your address on the public record.
What happens if my South Dakota LLC has no registered agent?
The state can refuse filings, mark the company as not in good standing and eventually administratively dissolve it. Worse, a lawsuit can proceed without you ever being properly notified. Keeping a registered agent on file is one of the cheapest forms of protection a company has.
Can I use a registered agent address as my business address?
A registered agent address is for legal and state mail only. If you need a business street address for banking, invoices or your website, add a virtual business address — Incofile offers one alongside registered agent service.
How do I change my registered agent in South Dakota?
File a change-of-registered-agent form with the South Dakota Secretary of State, Division of Business Services and pay any state fee. Incofile can prepare and file it for you ($119, which includes a year of our registered agent service) so there is no gap in coverage.
