Form Your Michigan LLC Without the Guesswork

If you run a business as a sole proprietor in Michigan, there is no legal line between you and the company. A supplier you can't pay, a customer who sues, a contractor who gets hurt on a job. Those become claims against your own bank accounts, your vehicle, and potentially your house. A limited liability company puts a legal wall between the two, so that in most situations the business is the party that owes money or gets sued, not you personally.

Michigan LLCs are created and governed under the Michigan Limited Liability Company Act, Act 23 of 1993. Once your company is on file, it becomes its own legal person: it signs the contracts, holds the bank accounts, owns the equipment, and carries the liability. The members (the owners of an LLC) are generally shielded from the company's debts and legal judgments as long as the business is run as a genuine separate entity.

What the liability shield really covers

"Limited liability" is not a magic word that makes every obligation disappear. If you personally sign a guarantee on a lease or a business loan, you are personally responsible for that specific debt regardless of the LLC. And if you treat the company's money as your own (paying your mortgage out of the business account, running personal purchases through the company card), a court can decide the LLC is a sham and let a creditor reach your personal assets. Lawyers call that "piercing the veil."

The protection stays intact when you keep things separate: a dedicated business bank account, clean bookkeeping that doesn't mix personal and business spending, and contracts signed in the company's name rather than yours. For the overwhelming majority of Michigan freelancers, tradespeople, shop owners, and small operators, the LLC hits the sweet spot: far more protection than a sole proprietorship, far less formality than a corporation.

How a Michigan LLC is taxed

By default the IRS does not tax the LLC itself. A single-member LLC is treated as a "disregarded entity," meaning you report the business income on your personal federal return, usually on Schedule C. A multi-member LLC is taxed as a partnership, with profits and losses flowing through to each member's personal return. Michigan then taxes that same income at the individual level through the state income tax. If it makes financial sense down the road, an LLC can elect to be taxed as an S corporation, which some owners use to reduce self-employment tax once profits are consistent. That's a decision to make with an accountant, not a default worth rushing into.

Business entity filings in Michigan are not handled by the Secretary of State the way they are in many states. They run through the Department of Licensing and Regulatory Affairs (LARA), specifically the Corporations, Securities & Commercial Licensing Bureau, Corporations Division. You'll do almost everything through the state's online system, the MiBusiness Registry.

The document that actually creates the company is the Articles of Organization. It's a short filing that captures the LLC's name, the address of its registered office, the name of its resident agent, and any optional provisions, such as a later effective date of up to 90 days. You do not list the members, describe your line of business, or disclose any finances. Michigan uses the term "resident agent" where most states say "registered agent": same role, different label.

Processing timeline

LARA says review of a non-expedited submission can take up to 10 business days, and it posts a "processed through" date on its Business Entity Search so you can see how far the queue has moved. Paper Articles can still be mailed with a check to the Corporations Division in Lansing, but the state strongly encourages online filing. If a lease, a bank appointment, or a contract depends on the company existing by a certain day, Michigan sells expedited review for new filings: $50 for 24 hours, $100 for same day, $500 for two hours, or $1,000 for one hour, on top of the $50 filing fee.

What the Articles of Organization capture

• Company name: Must contain "limited liability company," "L.L.C." or "L.C." (periods optional, so "LLC" works), must not contain "corporation," "incorporated," "corp." or "inc.," and must be distinguishable from other names already on file with LARA.
• Registered office address: A physical street address in Michigan. A post office box can appear only as a separate mailing address, never as the registered office itself.
• Resident agent: A Michigan resident whose home or business office is the registered office, or a corporation or LLC authorized in Michigan with a business office there. The LLC can't name itself.
• Management and duration: If managers rather than members will run the company, the Articles have to say so. A duration only goes in if the LLC isn't meant to be perpetual.

Forming the LLC is a one-time act. Keeping it alive is a yearly one, and the yearly part catches people off guard because it's easy to forget once the excitement of launching fades.

The annual statement

Every Michigan LLC has to file an annual statement with LARA. Michigan's deadline is February 15 each year, which is unusual. Most states tie the due date to your formation anniversary, but Michigan uses a fixed calendar date for all LLCs. The statement is a short confirmation of your resident agent and registered office; it is not a financial report and asks nothing about revenue or profit. It's filed online only through the MiBusiness Registry (paper statements stopped being accepted in June 2025), filing opens October 15, and the state fee is $25.

An LLC formed late in the year gets a small break: a company formed after September 30 doesn't file on the February 15 that immediately follows its formation, so its first statement comes due the February after that. Beyond that, February 15 is the date to circle every year.

If a statement is missed

Michigan doesn't dissolve an LLC for skipping its statement, and a regular LLC owes no late fee (the $50 penalty applies to professional LLCs). The damage builds slowly instead. After two consecutive years without a filing, LARA sends a notice, and if the company doesn't catch up within 60 days it falls out of good standing under MCL 450.4207a. At that point it can't get a certificate of good standing, LARA accepts no filing except a restoration, and the company's name becomes available to another entity. Restoring good standing costs $50 plus $25 for each missed statement.

Keeping your resident agent current

Your resident agent and registered office have to stay valid for the entire life of the company. If the agent moves, resigns, or simply stops being reachable, you're expected to file a change with LARA to keep the record accurate. An LLC with a stale or invalid resident agent is technically out of compliance even when the annual statement is filed, and worse, legal papers served on a dead address may never reach you.

Licenses and taxes

Michigan doesn't issue a single general business license that covers everyone. Instead, licensing depends on your industry and often on your city or county: a restaurant, a contractor, and a salon each face different requirements. Separately, if you sell taxable goods or certain services, you'll register with the Michigan Department of Treasury for sales tax and file returns on the schedule the Treasury assigns. None of this happens automatically when you form the LLC; each is its own step on its own timeline.

Every Michigan LLC must name a resident agent at formation and keep one for as long as the company exists. The resident agent is the official contact point between your business and the state, and the address where anyone suing the company delivers legal process.

What the resident agent receives

• Service of process: lawsuits, summonses, and subpoenas aimed at the company
• State notices from LARA, including annual statement reminders and compliance actions
• Official correspondence tied to the entity's record

The resident agent has to be reachable at a physical Michigan street address, the "registered office." That's the whole point: the state wants a dependable place to hand someone a lawsuit. A P.O. box can serve only as a separate mailing address, and the agent's name goes on LARA's public record.

Your options

You can act as your own resident agent if you live in Michigan and don't mind that address appearing in LARA's public database, which search engines index. You can name a trusted individual with a Michigan address, such as a partner or attorney. Or you can hire a commercial resident agent service, which keeps a professional address on the public record instead of your home, and makes sure someone is always present to receive documents even when you're on vacation or out on a job.

Mainstay Filing prepares and submits your Michigan formation paperwork so you don't have to learn the MiBusiness Registry interface, second-guess the Articles of Organization, or wonder whether you've met every LARA requirement.

When you place an order, you give us the details the state needs: your chosen company name, your address, your management preference, and your resident agent choice. We prepare the Articles of Organization, file them with the Corporations Division, and send you the completed documents once the state processes them. Resident agent service is included, so your home address stays out of the public record and there's always a staffed Michigan address ready to receive legal mail on the company's behalf.

We also apply for the company's EIN with the IRS (the number itself is free). After the company is live, we prepare and file the February 15 annual statement each year, so the date never depends on your memory. The aim is simple: get your entity active and keep it in good standing without turning you into an expert on Corporations Division procedure.

What we don't do

Think of us as a filing service rather than a law firm or accounting practice. We don't give legal advice, tax advice, or help you negotiate ownership splits between partners. Those conversations belong with a Michigan attorney or a CPA. What we do is make sure the state-facing paperwork is accurate and on time, so you can spend your attention on the business rather than the bureaucracy.
