Starting an LLC in Michigan
A founder’s walk-through of entity selection, formation documents, and the operating agreement decisions that matter.
Updated April 2026
The limited liability company is the default entity choice for most new Michigan businesses — and for good reason. It offers liability protection, flexible tax treatment, and far less corporate formality than a traditional corporation. But the filing itself is the easy part. The decisions made in the weeks around formation — how ownership is split, how governance works, what happens if a member leaves — are the ones that matter years later.
1. Does an LLC Actually Fit?
Before filing, confirm the LLC is the right vehicle. An LLC is usually the right choice when the business has one or more owners, plans to operate for profit, and wants liability protection without the overhead of a corporation. Reasons to consider an alternative include:
- You plan to raise institutional venture capital. Most VC funds prefer — and many require — Delaware C corporations.
- You’re in a licensed profession. Michigan requires a professional limited liability company (PLLC) for law, medicine, and certain other licensed fields.
- The business is a true solo operation with no employees or contracts. Sole proprietorship may be adequate, though liability exposure is higher.
2. Filing the Articles of Organization
Michigan LLCs are created by filing Articles of Organization with the Department of Licensing and Regulatory Affairs (LARA). The filing itself is short — name, registered agent, purpose, duration — but a few points deserve thought:
- Name availability. Run a name search through LARA before committing. The name must be distinguishable from existing Michigan entities and must include “LLC” or “Limited Liability Company.”
- Registered agent. This is the person or service authorized to receive legal notices on behalf of the company. Use a dedicated registered agent service if you work from home, travel frequently, or value privacy.
- Principal office. Distinct from the registered agent’s address — this is where the business operates.
Common Mistake
Filing the Articles and stopping there. The Articles do not govern how the company actually runs — the operating agreement does. Without one, Michigan’s default rules apply, and they are almost never what the members want.
3. The Operating Agreement
This is the document that matters most. It governs ownership percentages, capital contributions, profit and loss allocation, voting rights, management structure (member-managed vs. manager-managed), distributions, transfer restrictions, and what happens when a member leaves — voluntarily or otherwise.
Even a single-member LLC benefits from a written operating agreement. It reinforces the separation between owner and entity, which is central to liability protection.
4. Tax Elections
By default, a single-member LLC is taxed as a sole proprietorship and a multi-member LLC is taxed as a partnership. The LLC can elect to be taxed as an S corporation or C corporation instead. The right answer depends on income level, owner compensation, and long-term plans. Talk to a tax advisor — the election has real consequences and a deadline.
5. After Formation
- Obtain an EIN from the IRS.
- Open a dedicated bank account — keep business and personal funds separate.
- Register for applicable state taxes (sales, withholding) through Michigan Treasury.
- File annual statements with LARA each February.
- Review and update the operating agreement as ownership or structure evolves.
Common Pitfalls
- Operating without an operating agreement and relying on handshake understandings.
- Commingling personal and business finances, which can undermine liability protection.
- Missing the annual filing and letting the LLC fall out of good standing.
- Adding a member without documenting the admission and updating the operating agreement.
- Overlooking the federal BOI reporting requirements that apply to most new LLCs.
Formation is a starting point, not a finished product. The real work is making sure the entity keeps pace with how the business actually grows.
