What Is an LLC in Michigan?
A limited liability company formed under the Michigan Limited Liability Company Act (MCL 450.4101 et seq.) is a distinct legal entity, separate from its owners, that combines the liability shield of a corporation with the operational flexibility of a partnership. Michigan adopted the Act in 1993 as Act 23 of the Public Acts, and it has been amended multiple times since, most recently to accommodate low-profit limited liability companies (L3Cs) and to modernize electronic filing requirements.
Members of a Michigan LLC are not personally liable for the company’s acts, debts, or obligations solely because of their membership status, as stated in MCL 450.4501(4). Their exposure is generally capped at what they have contributed to the company. Governance rests with the members by default, but the articles of organization may shift management authority to one or more designated managers—a structural choice explored in more detail in the filing section below. For federal income tax purposes, a single-member LLC is disregarded, and a multi-member LLC is treated as a partnership. However, either may elect corporate classification by filing IRS Form 8832. Michigan does not impose an entity-level income tax on LLCs that retain pass-through status; members pay the state’s flat 4.25% individual income tax on their distributive share of company earnings.
Michigan LLC Name Search
A proposed LLC name must be distinguishable on LARA’s records from every active corporation, limited partnership, and limited liability company already on file in the state. MCL 450.4204 sets out both what the name must include and what it may not contain. Every domestic LLC name must carry one of three permitted designators: “Limited Liability Company,” “L.L.C.,” or “L.C.” — with or without periods or other punctuation. Michigan’s statute is narrower than many states on this point; abbreviations like “LLC” without periods are not listed as approved designators in MCL 450.4204(1), though LARA has accepted “LLC” in practice on its standard forms.
The statute expressly prohibits the words “corporation” and “incorporated” and the abbreviations “corp.” and “inc.” in an LLC name. A name also cannot contain any word or phrase implying the company is organized for a purpose other than the one stated in its articles of organization, a requirement that ties the naming rules directly to the purpose clause filed at formation. Words suggesting banking, insurance, or professional licensing authority may trigger additional scrutiny or require proof of licensure before LARA will accept them.
Organizers can check name availability through the MiBusiness Registry Portal, which LARA launched in June 2025 to replace the older CSCL online filing system. LARA’s own naming guidance advises prospective members to wait until the articles of organization are actually filed before ordering signs, business cards, or stationery, since a passing search result does not guarantee the name will survive review.
Name Reservation: Under MCL 450.4205, a person may reserve an LLC name by filing an application with LARA. The reservation expires at the end of the sixth full calendar month following the month of filing — effectively a roughly 180-day hold. The reservation application is Form CSCL/CD-540, and the fee for an LLC name reservation is $25. The right to the reserved name may be transferred to another person by filing a notice of transfer.
Choosing an LLC Registered Agent in Michigan
Michigan’s statute uses the term resident agent rather than the more common “registered agent,” though the role is identical. Under MCL 450.4207, every domestic LLC must continuously maintain both a resident agent and a registered office in the state. The resident agent is the person or entity appointed to accept service of process, official notices, and any legal demand directed at the company. The registered office is the Michigan Street address, not a P.O. Box, where that agent can be found during normal business hours.
Eligibility for the role is defined by the statute itself. An individual must be a Michigan resident whose business office or personal residence matches the registered office address. An entity may serve if it is a domestic corporation, a foreign corporation authorized to transact business in Michigan, a domestic LLC, or a foreign LLC authorized to transact business in the state. The LLC being formed cannot serve as its own resident agent, a point LARA confirms in its annual reports and statements guidance, which states: “A business cannot serve as its own resident agent.”
If the LLC fails to appoint or maintain a resident agent, or the agent cannot be found through reasonable diligence, MCL 450.4207(4) permits service of process by delivering or mailing a summons and complaint directly to LARA. Beyond this procedural consequence, allowing the resident agent position to lapse can lead to dissolution of the LLC and loss of good standing after a two-year grace period, stripping the company of its right to maintain lawsuits in Michigan courts and potentially exposing its name to claims by other entities.
LLC Filing Requirements in Michigan
An LLC in Michigan is brought into existence by filing executed articles of organization with LARA’s Corporations Division. MCL 450.4202 provides that “one or more persons, who may or may not become members, may be the organizers” of the company, meaning the individual who signs and files the formation document need not have any ownership interest in the resulting LLC. Once LARA endorses the articles with the word “filed” and the date, the LLC’s existence begins, and that filing is “conclusive evidence that all conditions precedent required to be performed under this act are fulfilled.”
The formation document is Form CSCL/CD-700 — Articles of Organization for a Domestic Limited Liability Company. The filing fee is $50. Under MCL 450.4203, the articles must contain:
- The LLC’s name, including one of the approved designators
- The purposes for which the LLC is formed (a general-purpose statement covering “any activity for which limited liability companies may be formed under this act” is sufficient)
- The street address and mailing address of the initial registered office, and the name of the initial resident agent at that address
- A statement that the business is to be managed by or under the authority of managers, if the LLC will not use the default member-managed structure
- The maximum duration of the LLC, if other than perpetual
The articles may also include any optional provision consistent with the Act, including provisions that would otherwise appear in an operating agreement. The articles need not enumerate the LLC’s powers, which are granted automatically by MCL 450.4210 and mirror those available to Michigan business corporations.
- Online: Filings are submitted through the MiBusiness Registry Portal, which requires the organizer to create an account before proceeding.
- By Mail: The completed form, along with a check or money order for $50 payable to the State of Michigan, should be sent to Corporations, Securities & Commercial Licensing, Corporations Division, P.O. Box 30054, Lansing, MI 48909.
- In Person: Walk-in filings are accepted at LARA’s office on the 1st Floor, 2407 N. Grand River Ave., Lansing, MI 48906.
Standard processing may take up to two weeks. Expedited turnaround is available under MCL 450.4104(8) at the following tiers, each charged in addition to the base filing fee: $50 for 24-hour processing of formation documents, $100 for same-day formation processing, $500 for two-hour same-day processing, and $1,000 for one-hour same-day processing. LARA may set cutoff times for same-day requests.
A delayed effective date may be specified in the articles, but it cannot be more than 90 days after the date of delivery to LARA. If no delayed date is specified, the LLC exists as of the date the articles are endorsed.
Note: Every Michigan LLC must file an annual statement with LARA by February 15 each year, and pay a $25 filing fee. An LLC formed after September 30 is excused from filing the statement on February 15 immediately following formation. A late filing triggers a $50 penalty, and failure to file for two consecutive years results in dissolution.

LLC Operating Agreement in Michigan
Michigan does not mandate that an LLC adopt an operating agreement, but the Act gives the document a defined and significant role. MCL 450.4102(2)(r) defines it as “a written agreement by the member of a limited liability company that has 1 member, or between all of the members of a limited liability company that has more than 1 member, of the affairs of the limited liability company and the conduct of its business.” Notably, Michigan’s definition limits the operating agreement to a written instrument; oral operating agreements are not recognized under the Act, which distinguishes Michigan from the growing number of states that allow oral or implied agreements.
The operating agreement is never filed with LARA. It is an internal governance document that the members retain and may amend by agreement. Its practical importance, however, is difficult to overstate. Without one, the statutory default rules control every aspect of the LLC’s internal operations, and those defaults often do not match what the members actually intend. Under MCL 450.4401, the LLC is managed by all of its members unless the articles of organization specifically designate manager management. Under MCL 450.4303, distributions are split equally among all members, regardless of how much each contributed, unless an operating agreement provides otherwise. And under MCL 450.4506, an assignee of a membership interest cannot become a full member without a unanimous vote of the existing members, unless the operating agreement provides otherwise.
A well-drafted operating agreement should address management authority and the scope of any manager’s power, capital contribution obligations, allocation of profits and losses, restrictions on transfer of membership interests, procedures for admitting new members or handling a member’s withdrawal, and the events triggering dissolution beyond those listed in MCL 450.4801. Even a single-member LLC benefits from having a written operating agreement on file, because it provides documentary evidence of the separation between the member’s personal assets and the company’s property — a distinction that courts scrutinize when deciding whether to respect the LLC’s liability shield.
How to Get an EIN for an LLC in Michigan
A federal Employer Identification Number is the nine-digit identifier the Internal Revenue Service assigns to an LLC for tax reporting purposes. Michigan’s formation process does not automatically generate a federal tax ID, so the organizer must apply separately once LARA has accepted the articles of organization. An EIN is required whenever the LLC has employees, files certain federal excise tax returns, or withholds income tax paid to a non-resident alien. A single-member LLC with no employees can technically operate without one, but most Michigan banks will not open a business checking account without an EIN, and having one is broadly advisable.
The IRS EIN Online Application is the fastest route—it issues the number immediately upon successful submission. The tool is available Monday through Friday from 6:00 a.m. to 1:00 a.m. the next day, Saturday from 6:00 a.m. to 9:00 p.m., and Sunday from 6:00 p.m. to midnight, all Eastern Time. The applicant must have a valid Social Security Number or Individual Taxpayer Identification Number, and the LLC must already exist as a filed entity with LARA before the IRS will process the application.
For applicants who cannot use the online tool, IRS Form SS-4 may be submitted by fax (with an approximate four-business-day turnaround) or by mail (four to five weeks). The form requires the name and taxpayer identification number of the LLC’s responsible party—the individual who owns, controls, or exercises ultimate effective control over the entity. There is no fee for obtaining an EIN regardless of the method used.
Note: The IRS limits applicants to one EIN per responsible party per day through the online tool. Plan accordingly if forming multiple entities simultaneously.
Registering for State Taxes in Michigan
Michigan taxes LLC income at the member level rather than the entity level, provided the LLC retains its default federal pass-through classification. Members report their distributive share on an individual MI-1040 return at the state’s flat 4.25% individual income tax rate. The state does not impose a franchise tax, gross receipts tax, or any other annual entity-level tax on standard pass-through LLCs. The $25 annual statement filed with LARA is an administrative filing, not a tax.
An LLC that elects to be taxed as a C corporation through IRS Form 8832 becomes subject to Michigan’s 6% Corporate Income Tax (CIT), administered by the Michigan Department of Treasury. The CIT replaced the Michigan Business Tax for most filers effective January 1, 2012. Taxpayers with gross receipts of less than $350,000 and a tax liability of $100 or less are not required to file.
Michigan also offers an elective Flow-Through Entity Tax that allows qualifying pass-through entities, including multi-member LLCs, to pay Michigan income tax at the entity level. The election is irrevocable for three years and is designed to provide members with a workaround to the federal $10,000 cap on state and local tax deductions. The FTE tax rate mirrors the individual income tax rate.
An LLC selling tangible personal property or certain taxable services in Michigan must hold a sales tax license. Michigan’s sales tax rate is 6%, and the license is valid from January 1 through December 31 of each year. Registration is completed through Michigan Treasury Online (MTO), the Department of Treasury’s electronic portal. New licenses can be issued within seven business days of completing the online e-Registration.
| Tax Type | Agency | Registration Method | Fee |
| Individual Income Tax (member level) | Michigan Department of Treasury | Reported on individual MI-1040 | None for registration |
| Sales and Use Tax | Michigan Department of Treasury | Michigan Treasury Online (MTO) | No registration fee |
| Flow-Through Entity Tax (elective) | Michigan Department of Treasury | MTO e-Registration | No registration fee |
| Corporate Income Tax (if electing C corporation status) | Michigan Department of Treasury | MTO e-Registration | No registration fee |
Registering as an Employer in Michigan
An LLC that brings on employees in Michigan triggers registration obligations with three separate state agencies—the Unemployment Insurance Agency, the Department of Treasury, and (indirectly) the Workers’ Disability Compensation Agency. Each registration serves a different function, and all must be completed promptly after the first employee’s start date.
Unemployment Insurance: The Unemployment Insurance Agency (UIA), housed within the Department of Labor and Economic Opportunity, administers Michigan’s unemployment insurance program. Employers register through the MiWAM employer portal, which requires creating a MiLogin for Business account. After registration, UIA assigns an Employer Account Number and mails an authorization code to the business address within 10 business days; this code must be entered to gain full account access.
State Income Tax Withholding: Because Michigan levies a flat 4.25% income tax on wages, every employer must register with the Department of Treasury to withhold and remit that tax. Withholding registration is bundled into the business tax e-registration process on Michigan Treasury Online. The LLC’s federal EIN serves as the Treasury account number.
Workers’ Compensation Insurance: Under the Workers’ Disability Compensation Act, nearly all Michigan employers must carry coverage. Private employers who regularly employ one or more workers for 35 or more hours per week for 13 or more weeks in the preceding 52 weeks are subject to the requirement. Most employers purchase a policy from a private insurance carrier, though some qualify for self-insured status or participate in a group fund. The Workers’ Disability Compensation Agency within LEO oversees compliance and provides guidance on coverage thresholds.
New Hire Reporting: Federal and Michigan law require employers to report each newly hired or rehired employee. Reports are submitted to the Michigan Office of Child Support through the Michigan New Hires Operation Center or by calling (800) 524-9846. Timely reporting helps the state enforce child support orders and verify eligibility for public assistance programs.
| Obligation | Agency | Registration Method |
| Unemployment Insurance | Unemployment Insurance Agency (LEO) | MiWAM Employer Portal |
| State Income Tax Withholding | Michigan Department of Treasury | Michigan Treasury Online (MTO) |
| Workers’ Compensation | Workers’ Disability Compensation Agency (LEO) | Private carrier, self-insurance, or group fund |
| New Hire Reporting | Office of Child Support (MDHHS) | Michigan New Hires Operation Center |
The LLC must also meet federal employer obligations: filing IRS Form 941 each quarter to report payroll taxes, paying Federal Unemployment Tax Act (FUTA) contributions, and completing Form I-9 for every new hire to verify employment eligibility.
