South Dakota Certificate of Authority Filing Service

Foreign Corporation in SD

If you are a corporation based in another state and want to transact business in South Dakota, you will need a Certificate of Authority from the State of South Dakota. This is obtained by submitting paperwork as a foreign corporation with the South Dakota Secretary of State, Corporations Division. Once filed, the State of South Dakota will return a completed certificate of authority to you. A foreign South Dakota corporation is not to be confused with an out-of-country corporation. Any corporation not actually formed (created) in South Dakota is a foreign corporation.

We only charge for the state filing fees plus $100 to prepare and file the foreign South Dakota corporation Certificate of Authority form to the Corporations Division of the South Dakota Secretary of State. We will also find the paperwork needed from your home state of incorporation to file your documents.

If you want to submit the paperwork yourself: you just need to sign up for our South Dakota registered agent service and the foreign South Dakota corporation form is in your client account immediately. You’ll also find some tips on how to submit your paperwork with the state. You are required to have a registered agent in South Dakota anyway, so we try to make this a simple process for you, whether you want us to submit your papers or you want to do the filing yourself.

What Are My Next Steps?

Just sign up for our registered agent service first. Next, you can look at the form for foreign corporations in your online account and also at the included filing tips. If you decide not to fill out and submit the forms yourself, you just click the “add services” tab from your account, and add our filing services for the state filing fees plus $100. Your account shows real time status of our work in progress. Once we are done with your foreign corporation registration in South Dakota, we always upload the filing to your client account, email you a copy, and send you the original filed documents by mail.
