Michigan does not authorize series LLCs. The state’s Limited Liability Company Act contains no provisions for creating internally separated series within a single filing, so a true series LLC in Michigan isn’t available as a domestic entity. You have two realistic options: form the series LLC in a state that recognizes them (Delaware, Illinois, Texas, or Nevada) and register it here as a foreign LLC, or use a Michigan-native alternative like multiple separate LLCs or a holding company structure.
Why Michigan Doesn’t Offer a Series LLC
A series LLC is one entity that contains multiple internal divisions, sometimes called cells. Each series can hold its own assets, take on its own debts, and have its own members. The point of the structure is the internal liability shield: if one series is sued, creditors reach only that series’ assets, not the master LLC or any sister series. Real estate investors gravitate to the format because each property can sit in its own series without a separate LLC filing for every building.
Roughly 20 states have adopted some version of series LLC legislation. Michigan is not one of them. The state overhauled its LLC Act through Public Acts 557 and 558 of 2018, effective 2019, but the legislature did not add series provisions then and has not added them since. Michigan’s LLC Act, codified starting at MCL 450.4101, covers formation, management, member rights, and dissolution of standard LLCs.1Michigan Legislature. Michigan Compiled Laws 450.4402 No provision authorizes series or internal liability shields between divisions of a single LLC. Some online guides claim otherwise, so treat any source that cites Michigan statute as authorizing a series LLC with skepticism.
Registering an Out-of-State Series LLC in Michigan
Some business owners form a series LLC in Delaware, Illinois, Texas, or Nevada and then register that entity as a foreign LLC in Michigan. It sounds clean in theory. In practice, three problems come with it.
You pay twice. Formation fees in the home state, foreign registration fees in Michigan, then annual compliance obligations in both jurisdictions. For an investor holding three or four rental properties, doubled administrative costs can consume the savings that made the series structure attractive in the first place.
The bigger issue is legal. Michigan courts have not definitively addressed whether they will honor the internal liability shields of a foreign series LLC. States without their own series statutes may not recognize the wall between one series and another during litigation. If you are sued in Michigan over a property held by one series, a Michigan court could treat the entire series LLC as a single entity and reach assets held by other series. This risk remains legally unsettled and is the strongest reason Michigan attorneys tend to steer clients away from the out-of-state approach.
Registering as a foreign LLC also doesn’t buy you out of Michigan’s rules. You still need a Michigan registered agent, still file annual statements, and remain subject to Michigan court jurisdiction for disputes arising from your operations here.
Michigan Alternatives That Actually Work
Multiple Separate LLCs
The most straightforward option is forming a separate Michigan LLC for each asset or business line you want to protect. Each LLC is its own legal entity with its own liability shield. A judgment against one cannot reach the assets of another. This is the structure Michigan attorneys most frequently recommend for real estate investors because the protection is clear and well-established under Michigan law.
The cost is the trade-off. Each LLC requires its own Articles of Organization filing, its own annual statement, and its own record-keeping. At $50 per formation and $25 per year in annual fees, expenses grow with your portfolio.2Department of Licensing and Regulatory Affairs. Limited Liability Company Filing Information
Holding Company Structure
A holding company approach uses one parent LLC that owns membership interests in multiple child LLCs. The parent centralizes management; each child holds a single asset or business line. This produces the same compartmentalization as a series LLC, and Michigan has well-developed case law supporting liability separation between parent and subsidiary entities. Every subsidiary still needs its own formation, its own EIN, and its own annual compliance, so the cost profile mirrors the multiple-LLC route.

Articles of Organization
You file Articles of Organization on LARA Form 700. Form 500 is for profit corporations, not LLCs, so ignore any guide that points you there.3Michigan Department of Licensing and Regulatory Affairs. Limited Liability Company Forms The form asks for the LLC name, the name and Michigan street address of your registered agent, and whether the LLC will be member-managed or manager-managed.
Your name must be distinguishable on LARA’s records from every other active corporation, LLC, and limited partnership name in Michigan, and it must include “Limited Liability Company,” “LLC,” or “L.L.C.” LARA ignores those required designators and punctuation-only differences when checking availability.4Michigan Department of Licensing and Regulatory Affairs.

Operating Agreement
Michigan does not require you to file an operating agreement with the state, but you need one. It governs management, allocation of profits and losses, what happens when a member leaves, and how disputes are resolved. If you are using multiple LLCs to segregate assets, each operating agreement should clearly identify which assets belong to that LLC and prohibit commingling of funds with any other entity you own. That documentation matters if a creditor ever tries to argue your entities are really one operation.
Annual Compliance
Every Michigan LLC files an annual statement with LARA by February 15 and pays $25.6Michigan Legislature. Michigan Compiled Laws 450.4207 LLCs formed after September 30 skip the following February filing. The statement updates your registered agent and registered office address.
Miss two consecutive filings and your LLC loses good standing. The LLC still legally exists and can still transact business, but you won’t be able to obtain a certificate of good standing, which banks, lenders, and business partners often require.2Department of Licensing and Regulatory Affairs. Limited Liability Company Filing Information Some guides call this “automatic dissolution.” That’s inaccurate for LLCs; automatic dissolution after two missed filings applies to Michigan corporations under a different statute.
Banking and Record-Keeping
Whether you use multiple Michigan LLCs or a foreign series LLC registered here, the liability shields only hold if you run each entity as a genuinely separate business. Each entity or series needs its own bank account, its own books, and its own records. Commingling funds is the fastest route to a court piercing the veil and treating everything you own as one operation.
Banks vary in how they handle series LLCs. If you go that route, call ahead. Some banks will only open an account for the master LLC and refuse separate accounts for individual series. Others want articles of organization, an operating agreement, and an EIN for each series before proceeding. Michigan regional banks and credit unions tend to be more flexible on this than national chains. Standard Michigan LLCs are simpler: each opens its own account with its own EIN, keeps its own books, and moves money to another entity only as a documented loan or distribution. That simplicity is part of why many Michigan attorneys prefer the multiple-LLC approach over importing a series structure from another state.
Federal Tax Treatment If You Use a Foreign Series LLC
The IRS proposed regulations in 2010 that would treat each series as a separate entity for federal tax purposes, with its own classification under the check-the-box rules. Those regulations have never been finalized, leaving the area in a gray zone that has now persisted for over 15 years. In practice, most tax professionals recommend obtaining a separate EIN for each series and filing separate returns. Disregarded series report on the owner’s individual return; multi-member series file their own partnership returns.
On the reporting side, FinCEN exempted all domestic entities from Beneficial Ownership Information reporting under the Corporate Transparency Act as of March 2025, so neither a master LLC nor individual series currently need to file BOI reports.7FinCEN.gov. Beneficial Ownership Information Reporting
