Single-Member LLCs

Single-member LLCs in Michigan are not required to obtain an EIN for federal tax purposes if they are treated as a “disregarded entity” for tax purposes.

  • Maintaining a clear separation between personal and business finances
  • Complying with certain Michigan tax and licensing requirements

Multi-Member LLCs
