Designate a South Dakota Registered Agent

Every South Dakota corporation must designate a South Dakota registered agent. According to South Dakota law (SD Codified L § 59-11-20), the duties of a registered agent include receiving and forwarding any official legal correspondence like service of process or subpoenas.

That means your registered agent must be able to:

  • Maintain a South Dakota street address
  • Be available during normal business hours to receive service of process
  • Forward registered agent mail to you in a timely fashion

Any legal adult or company who meets the above criteria can serve as your registered agent. It’s important, however, that whoever serves as your registered agent can be someone you can count on to receive and forward your registered agent mail ASAP. Otherwise, you risk missing important state correspondence, which could mean financial penalties and even revocation of your right to do business in South Dakota.

Obtain a Certificate of Good Standing

After designating a registered agent, you’ll need to secure a Certificate of Good Standing form the state where you first formed your corporation. You might also see this document referred to as a “Certificate of Existence” in some jurisdictions. Don’t worry, they both mean the same thing: they certify that your corporation is in compliance with its home state. That means you’re up-to-date with your annual reports, taxes, licenses, and any other state obligations.

How Can I Get a Certificate of Good Standing?

The process to acquire a Certificate of Good Standing varies from state to state,. You can typically get a Certificate of Good Standing online through the Secretary of State’s website for a minor fee.

When Should I Get a Certificate of Good Standing?

You should request a Certificate of Good Standing before you start filling out your Application for Certificate of Authority. This allows you to have time to fill out your application, especially if you need to figure out things like your business name and designating a registered agent.

Note: Your Certificate of Good Standing must have been issued by your home state within 90 days prior to filing your foreign registration.

File Your South Dakota Application for Certificate of Authority

To complete the registration process, you will need to file an Application for Certificate of Authority with the South Dakota Secretary of State. Here’s everything you’ll be asked:

  • South Dakota business name
  • Legal business name in your home state (if you will be using a different name in South Dakota)
  • Principal address (primary address of your business in your home state)
  • Mailing address (if different from principal address)
  • Foreign address (required only if your home stated requires an in-state principal address)
  • Registered agent’s name and address (if using a commercial registered agent, you may list their CRA#)
  • Name of your corporation’s home state or jurisdiction
  • Date your corporation was initially formed
  • Date your corporation will commence doing business in South Dakota
  • Whether your corporation is manager-managed or member-managed
  • Signature from party authorized to do business on behalf of your corporation

South Dakota Corporation Naming Requirements

Not every state has the same naming requirements, and the name you registered for your corporation in its home state might not be available for use in South Dakota. According to SD Codified L § 47-34A-105, your South Dakota corporation name must:

  • Contain “corporation” or an acceptable variation such the “corporation” or abbreviations such as “Inc.”
  • Be distinguishable from the name of other reserved or registered business entities, including approved fictitious business names

You can confirm availability using the Business Name Availability tool provided by the SD Secretary of State. You can submit an Application for Reservation of Name if you see an available name that you like but you aren’t ready to file your Articles just yet. The filing fee is $25, and you may reserve a name for a period of 120 days.
