From Iowa to South Dakota, step by step
Order the Iowa certificate
The Certificate of Existence ($5) is ordered from Iowa separately; it is not part of our South Dakota order. South Dakota wants the Iowa certificate current, so it is ordered close to the filing date.
We prepare and file the registration
It names us as your South Dakota registered agent, with your Iowa name and formation date and the certificate attached. Iowa issues the certificate instantly, so the South Dakota filing can go in the same day. Once South Dakota approves it, the Iowa company can do business there.
