Operating Agreement For LLCs In Michigan (May. 2026)

Michigan law does NOT require LLCs to create and maintain an Operating Agreement. However, I strongly recommend you get one. It separates your personal and business assets, protects your business structure, and prevents misunderstandings between LLC members by clearly defining internal business rules and regulations.

In this guide, I’ve explained everything you need to know about the Operating Agreement for LLCs in Michigan. You’ll learn about what to include, how to safely store it, and the main benefits of maintaining one when operating in the state.

What Is An Operating Agreement For LLCs In Michigan?

An Operating Agreement for an LLC in Michigan is a foundational, internal written contract between the LLC’s members (Owners). It explains your LLC management structure, your company ownership, and member responsibilities.

All Michigan LLCs should prepare and maintain an Operating Agreement, regardless of whether you’re a single-member LLC or a multi-member LLC. It should be kept with your official company records, and all LLC members should keep an up-to-date, signed copy.

Your Operating Agreement becomes legally binding without needing approval from a Michigan government agency once it’s agreed to and signed by all LLC members. In the case of an audit, lawsuit, or major financial transaction, a financial institution or court may request a review of your Operating Agreement. This is done to verify your LLC ownership and management structure.

Your Operating Agreement may be needed for:

• Financial institutions, when opening a business bank account.
• Financial institutions, when applying for a loan.
• A title company if your LLC is purchasing real estate.

1. Does Michigan Require An Operating Agreement For An LLC?

You’re NOT legally required to draft and maintain an Operating Agreement in Michigan when forming and maintaining an LLC. This is according to the definition of “Operating Agreement” in Section 450.4102(r) of the Michigan LLC Act.

Furthermore, you do NOT need to file your Operating Agreement with the Michigan Secretary of State, Michigan Department of Licensing and Regulatory Affairs, or any other official government agency.

2. It Reflects Your LLC’s Management Structure

Your Operating Agreement should clearly describe the management structure that you’re following, including how decisions are made when operating under that model.

• Member-managed LLCs: All LLC members participate in daily business operations, decision-making processes, and management. This works best for small entities where all members want an active role in business decisions.
• Manager-managed LLCs: LLC members appoint one or more managers to make important business decisions and oversee daily operations. Other LLC members take a passive business role by acting as investors. This is better-suited for larger LLCs where members prefer not to be involved in daily business operations.

Where Should I Keep My Michigan Operating Agreement?

As an internal business document, you do NOT need to file your Michigan LLC Operating Agreement with the Division of Corporations, Business and Professional Licensing, or any other official government agency. It’s an important internal business document that should be kept with your official business records.

All LLC members should maintain an agreed-upon, signed written copy in digital and printed forms. While Michigan doesn’t ask for this document, it may be required by banks and financial institutions when applying for financing or opening a dedicated business bank account.

Why Do You Need An Operating Agreement For Your LLC?

Creating your Michigan LLC Operating Agreement provides fundamental business protection when operating in the state. While it’s not a legal requirement, it provides excellent financial, legal, and organizational benefits. I’ve discussed the main ones below:

• Confirms your LLC ownership structure: Your Operating Agreement clearly defines your LLC members and their respective ownership percentages, acting as official proof that you operate as an LLC. This is often required by lenders and most banks.
• Strengthens your limited liability protection: Having an Operating Agreement in place shows that your LLC is a separate legal entity under Michigan law. This helps maintain clear separation between your personal finances and business assets.
• Prevents internal business disputes: A well-drafted Operating Agreement provides well-defined rules and procedures regarding LLC profit distribution, decision-making processes, and conflict resolution. This helps prevent misunderstandings and disputes between LLC members.
• Overrides Michigan’s default LLC laws: Without an Operating Agreement in place, your LLC follows Michigan’s default state regulations. A customized Operating Agreement ensures that your LLC follows personalized financial and management procedures, ensuring efficient business operations.

When Should You Create Your Michigan Operating Agreement?

You can draft your Michigan Operating Agreement at three different time points when forming your LLC. This can be done before, during, or after formation, with each time point offering specific advantages and disadvantages.

The table below outlines the main ones relating to each time point. Use it as a quick reference guide when deciding when to make your Michigan Operating Agreement.

While each option has its advantages and disadvantages, the correct choice depends on your LLC workflow and how quickly you want to establish your LLC’s internal rules and regulations.

How To Create Your Michigan LLC Operating Agreement

Creating your LLC Operating Agreement in Michigan template may seem overwhelming. However, the process is fairly easy once you understand the key structure and elements involved. It should outline your key decision-making processes, operational procedures, and your ownership responsibilities.

In the next sections, I’ve written a step-by-step breakdown of your Michigan Operating Agreement. You’ll learn what to include in each section so you can draft a high-quality Operating Agreement that works.

1. Basic Information

Your Michigan LLC Operating Agreement must begin with your essential business details. Most of this information is already listed in your Articles of Organization. Therefore, it should match this closely to ensure you maintain consistency throughout your official business documents.

You should include the following:

• Your official legal LLC name (As registered with the state of Michigan).
• Your effective LLC date (When your company officially begins).
• Your Michigan Registered Agent details (Officially called your Resident Agent in Michigan).
• Your LLC’s purpose (The type of business activities that your company performs).
• Your LLC Operating Duration (Whether your LLC will operate indefinitely or for a specific period).
• Your LLC tax agreement (Outlined in your Federal Tax classification).

Including these details at the start of your Operating Agreement provides a solid foundation, ensuring that your key business information is clearly documented among LLC members.

2. Management Structure & Responsibilities

Your Michigan Operating Agreement must clearly define your LLC management structure, outlining the different roles and responsibilities of all members. As I’ve mentioned above, you can choose to be a member-managed or managed-managed LLC.

• Member-managed LLC: All LLC members take part in daily business operations and key decision-making processes.
• Manager-managed LLC: LLC members appoint one or more managers to oversee daily business operations and make key business decisions.

Your Internal Operating Agreement should:

• Clearly define LLC members’ and managers’ decision-making authority and operational duties.
• Clearly explain who is responsible for major business decisions. This includes finance policies and significant business transactions.
• Describe the LLC procedures regarding business operations, compliance procedures, and internal controls.

3. LLC Ownership

The next part of your Operating Agreement should clearly list your Michigan LLC members and their respective ownership percentages. This is officially known as their LLC Membership Interest.

• This is commonly expressed as a percentage (10%, 50%, 100%).
• This shows how much of the LLC each member owns. This usually determines voting power, power distribution, and decision-making authority.

Clearly documenting LLC ownership ensures each LLC member understands their company stake and how it affects their rights and responsibilities.

4. Initial Capital Contributions

All LLC members should deposit their initial company capital contributions in your dedicated business bank account once your Michigan LLC is officially approved. This refers to the amount of money that each member puts into your LLC to fund early operations.

Your Internal Operating Agreement must list:

• All member names (Those who are making contributions).
• Member contribution amounts.
• Additional contribution details (If applicable).

Including this information ensures that all LLC members agree to and understand their respective financial involvements from the beginning. This helps maintain transparency regarding your LLC funding structure.

5. Tax Statement

Next, your Operating Agreement needs to specify your LLC tax agreement. Your LLC must choose one of the following Federal Tax treatments. This is because the Internal Revenue Service (IRS) does NOT assign default tax classifications based on state registration.

• Your LLC is taxed as a Sole Proprietorship: This applies to Single-Member LLCs.
• Your LLC is taxed as a Partnership: This applies to Multi-Member LLCs (Unless you choose another tax election).
• Your LLC is taxed as an S-Corporation: This requires you to file Form 2553 with the IRS.
• Your LLC is taxed as a C-Corporation: This requires you to file Form 8832 with the IRS.

Including your tax statement provides clarity among members, ensuring your LLC has the correct tax classification once it begins operating.

6. LLC Members Voting Rights

Your Michigan Operating Agreement must clearly explain your LLC member voting rules. This determines how decisions are made and the authority among members to approve important company actions.

• Member-managed LLCs: Voting power is commonly determined by members’ ownership percentages. This determines how members vote in major business decisions and their active management participation.
• Managed-managed LLCs: Voting power is still commonly determined by membership Interest. However, members use their votes to appoint or remove LLC managers. Appointed LLC managers can make decisions on everyday business operations without requiring approval.

Some business decisions ALWAYS require member approval. In this case, managers do NOT have voting authority.

This includes:

• Removing an existing LLC member.
• Adding new LLC members.
• Making significant changes to your LLC business structure.

Defining these rules in your LLC Operating Agreement means that each LLC member clearly understands how their ownership percentage affects their voting power and how key business decisions are made.

7. Membership Changes & Dissolution Procedures

Finally, your Operating Agreement must outline the membership changes and dissolution procedures. This ensures that your LLC can smoothly transition if needed and remain compliant according to Michigan law.

These are the key points to include:

• Clear steps for admitting new LLC members.
• Procedures for transferring ownership interests between members or to third parties.
• Voluntary member resignation and involuntary removal procedures.
• Member authority regarding LLC dissolution and related decision-making procedures.
• The processes for handling important company affairs. This includes distributing remaining assets, settling outstanding business debts, and closing business accounts.

Including these important rules and procedures ensures that all LLC members clearly understand what to expect during important business changes and transitions. Establishing consistent business processes for handling membership changes ensures that your LLC remains compliant according to state law.

Tips For Writing Your Michigan LLC Operating Agreement

A well-drafted Michigan Operating Agreement ensures that your LLC operates smoothly without costly and time-consuming misunderstandings. I’ve written some essential tips below to help you create a high-quality document:

• All information must be in writing: A written Operating Agreement provides clear guidelines on membership agreements and shows banks, lenders, and accountants reliable proof that your LLC is operating accordingly. Verbal agreements have less legal standing and can lead to confusion.
• All members must sign it: Ensure that all LLC members have agreed to and signed your Operating Agreement. This confirms that everyone understands what they’re signing and makes it legally binding. Make sure everyone has a physical and digital copy to reference in the case of internal disputes or operational changes.
• Keep your agreement up-to-date: It’s important that your Operating Agreement reflects your current business practices. It should be promptly updated when ownership percentages change, management roles and adjusted, and LLC members join or leave. Doing this means that your agreement reflects how your LLC actually operates, reducing the chances of confusion and poor legal standing.
