Operating Agreement For LLCs In Michigan (Aug. 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

First and foremost, your agreement has to reflect your chosen management structure. This will be either member or managed-managed.

So, in a member-managed LLC, all members participate and are involved in decision-making, which is great for businesses where everyone wants to take an active role.

If you choose to be manager-managed, members appoint one or more managers to take the reins, while other members sit back and act as passive investors. This is best for larger businesses where members prefer not to be too involved in day-to-day stuff.

Where Should I Keep My Michigan Operating Agreement?

Don’t worry too much about any official stuff here. It’s an internal business doc, meaning that it doesn’t need to be officially filed with the state or any government agency.

While it may be required by certain banks and financial institutions, it’s pretty straightforward if you store it correctly. Put it with your official business docs in a safe place and you’re good to go.

Simply make sure its kept up-to-date and signed by all current members to make it legally enforceable. You’ll need to get this done again every time you need to make an update.

Why Do You Need An Operating Agreement For Your LLC?

Get your agreement in place, and you give yourself the fundamental protection needed when operating in the state. Even though it’s not officially a legal requirement, it offers invaluable legal, financial, and operational benefits.

First up, it confirms your ownership structure. With each member and their respective ownership percentages being clearly defined, it shows official proof that you actually operate as an LLC.

Alongside this, you also increase your liability protection, which is perhaps the biggest benefit of having an LLC. Your agreement confirms that you’re a separate legal entity, which helps separate your business assets and personal finances.

If your agreement has well-defined rules and procedures in place, it can definitely help avoid potential internal disputes by offering conflict resolution solutions. You prevent potential misunderstandings and keep things running smoothly.

Without one in place you’re governed by the states default operating rules, which most likely will never align with your operating needs. Get your agreement sorted, and you have a set of personalized rules and procedures to ensure smooth operations throughout.

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.

As with most things, each option has its own pros and cons, meaning that the right choice depends on your workflow and desired formation timeline.

How To Create Your Michigan LLC Operating Agreement

It’s totally normal to find the creation process overwhelming at first glance. Even so, it’s fairly simple to implement once you’ve correctly understood the relevant sections involved.

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) and
• 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

Underneath your basic business info section, move on to your chosen management structure. This important section is put in place so that all members understand their respective roles and responsibilities.

If you’re member-managed, all members take part in daily operations and key decision-making procedures. Conversely, those in a manager-managed LLC tend to sit back while one or more appointed managers oversee key business decisions and operational procedures.

As part of this section, make sure you define each member/manager’s decision-making authority and operational duties. Members should also understand who is primarily responsible for key business decisions, including financial policies and significant transactions. Part of this should describe any operational and complaince procedures so everything is adequately covered.

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

Once your LLC has been officially approved, all members must deposit their initial contributions into your dedicated business bank account. This is basically an initial amount of money of investment given to fund early operations.

So, state contributing member names, contribution amounts, and additional details if applicable. Doing things this way ensures that each member agrees to and understands their initial investments from the get-go. It helps maintain transparency as your LLC grows and evolves.

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

Make sure you clearly outline member voting rules in a section of your agreement, specifying decision-making procedures and authority for important business actions.

Both management structures base voting power on ownership percentages. However, votes are used to appoint or remove managers in a manager-managed LLC.

There’s a caveat. Business decisions that always require member approval aren’t controlled by managers, which include adding or removing members and making significant changes to your business structure.

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

Get a well-drafted agreement in place to ensure smooth business operations without time-consuming misunderstandings and issues. Use the tips detailed below as useful reference points.

• 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 and
• 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.
