How Idaho companies register with South Dakota

Order the Idaho certificate
The Certificate of Existence ($10) is ordered from Idaho separately; it is not part of our South Dakota order. South Dakota wants the Idaho 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 Idaho name and formation date and the certificate attached. Once Idaho's certificate is in hand, South Dakota's filing goes in. After approval, your Idaho LLC is registered with South Dakota.

Will your Idaho name work for South Dakota?

South Dakota accepts your Idaho name if it includes 'limited liability company', 'limited company', or one of the abbreviations L.L.C., LLC, L.C. or LC (limited may be written Ltd. and company Co.). If the Idaho name already ends in LLC, it meets the rule. If South Dakota's records show it taken, you can use an alternate name for the Idaho company. South Dakota can hold a name for $25 before you file.
