Michigan . Operating Agreement

Why every Michigan LLC needs an Operating Agreement.

Michigan does not always require an LLC to file an Operating Agreement with the state, but every LLC needs one. It governs ownership, management, profit allocation, and what happens when things change. Without it, Michigan default rules apply, and they rarely match what you actually want.

What an Operating Agreement does

  • Defines ownership percentages . who owns what, and how much.
  • Sets profit + loss allocation rules, which can differ from ownership percentages.
  • Establishes management structure . member-managed vs manager-managed.
  • Governs voting and decision-making rights, including unanimous-consent items.
  • Spells out transfers + buyouts when a member leaves.
  • Provides dissolution procedures if the LLC winds up.
  • Preserves limited liability by documenting the separation between owner and entity.

Single-member vs multi-member Operating Agreements

Single-member LLC

Simpler agreement focused on liability separation, banking authority, succession, and intent to remain disregarded for federal tax (or elect Corp/S taxation).

Multi-member LLC

More involved. Adds capital contributions, profit/loss allocations, decision-making thresholds, buy-sell provisions, valuation methods, and deadlock procedures.
