A clarification: C and S are tax elections, not entity types

"C-Corp" and "S-Corp" are federal tax classifications, not separate South Dakota entity types. You form a Corporation with the SD Secretary of State, then elect either C taxation (the default) or S taxation by filing Form 2553 with the IRS. LLCs can also elect C or S taxation if it makes sense for their economics.
