Important considerations
- The initial filing fee is only one part of the cost. Annual reports, franchise taxes, registered-agent service, licenses, and local requirements may also apply.
- Tax registration depends on the business activity, location, employees, and tax programs that apply.
- Forming in South Dakota does not automatically eliminate registration requirements in the state where the business actually operates.
