Michigan PLLC vs. LLC: Which Licensed Professions Must Form One

September 6, 2026  ·  8 min read

If you hold a Michigan professional license, the first question to settle is narrow: does your license fall on the short list of professions that legally cannot operate through an ordinary LLC? For most licensed workers in Michigan — real estate agents, builders, cosmetologists, massage therapists, insurance producers — the answer is no, and a standard LLC is fine. But for about a dozen licensed professions, a Michigan PLLC (professional limited liability company) is the only limited-liability option available, and forming a regular LLC by mistake creates a filing you’ll eventually have to fix.

This guide walks through exactly which professions are affected, what changes when you form a professional entity, and what the filing looks like at LARA.

Michigan’s professional LLC rules live in Article 9 of the Michigan Limited Liability Company Act, at MCL 450.4901 through MCL 450.4910. The Act defines a “professional service” as a service that may lawfully be rendered only by a person licensed or otherwise legally authorized under Michigan law — and that may not lawfully be rendered by a company that is not a professional entity.

That second half is the part people miss. Lots of Michigan occupations require a license. Only a subset of them are restricted so that the entity delivering the service must itself be a professional entity. In practice, LARA’s Corporations Division draws that line using the same list of professions found in Michigan’s Professional Service Corporation Act (MCL 450.221 et seq.), which predates the LLC statute.

Professions that must form a Michigan PLLC

The professions LARA has historically treated as requiring a professional entity are:

ProfessionEntity required for limited liability
Attorney at lawPLLC (or PC)
Certified public accountantPLLC (or PC)
ArchitectPLLC (or PC)
Professional engineerPLLC (or PC)
Land surveyorPLLC (or PC)
Physician / surgeon (MD)PLLC (or PC)
Osteopathic physician / surgeon (DO)PLLC (or PC)
DentistPLLC (or PC)
ChiropractorPLLC (or PC)
OptometristPLLC (or PC)
Podiatrist (chiropodist)PLLC (or PC)
VeterinarianPLLC (or PC)

If your license is on that list, filing a standard Articles of Organization is not a shortcut — it’s a defective filing. LARA generally catches it, but not always, and a mismatched entity can surface later during a licensing board audit, a hospital credentialing review, a malpractice claim, or a due-diligence request when you sell the practice.

Licensed occupations that can use a regular LLC

These Michigan occupations require individual licensure or registration, but the license does not force you into a professional entity:

  • Residential builders and maintenance & alteration contractors — see our LLC guide for Michigan contractors
  • Electrical, plumbing, and mechanical contractors
  • Real estate salespersons, associate brokers, and brokers
  • Insurance producers and mortgage loan originators
  • Cosmetologists, barbers, estheticians, and salon owners — covered in our salon and barbershop LLC guide
  • Massage therapists
  • Registered nurses and nurse practitioners
  • Physical therapists and occupational therapists
  • Licensed professional counselors, social workers, and marriage and family therapists
  • Real estate appraisers
  • Bookkeepers and non-CPA accountants

One caution: the professions requiring a professional entity are set by statute and licensing-board interpretation, and interpretations do shift. If your field sits near the line — behavioral health, advanced practice nursing, certain allied health roles — call LARA’s Corporations Division and your own licensing board before you file. Ten minutes on the phone is cheaper than an amendment.

How the rules actually differ

Once you’re in professional-entity territory, five things change compared to a standard Michigan LLC.

1. Every owner must be licensed

Under Article 9, membership in a professional company is limited to individuals licensed in the profession the company practices (or to entities themselves wholly owned by such licensees). Your spouse cannot hold a passive 20% interest in your dental PLLC. An outside investor cannot buy in. A management company cannot take equity.

This is the single biggest structural difference, and it’s the one that derails deals. If you’re planning a practice with a non-licensed business partner, the equity has to sit outside the professional entity — typically in a separate management or real estate company that contracts with the PLLC at arm’s length. That’s a structure worth building with a healthcare or business attorney, not a template.

2. One profession per company

Michigan’s professional LLC provisions generally require the company to be organized to render one specific type of professional service, plus services ancillary to it. The statute makes limited allowance for certain related practices to combine, and health professions in particular have more flexibility than others.

The practical consequence: a CPA and an attorney generally cannot co-own a single PLLC that offers both accounting and legal services. Two dentists and an orthodontist can share one company. A physician and a physical therapist is a question to ask before you file, not after.

3. The name has to say so

Your entity name must include a professional designation — “Professional Limited Liability Company,” “P.L.L.C.,” or “PLLC.” “Ann Arbor Family Dentistry, LLC” won’t clear the name check for a professional entity. Beyond the state’s requirement, your licensing board may impose its own naming restrictions: attorneys, for example, operate under professional conduct rules governing firm names, and several health boards restrict names that imply a specialty the owners don’t hold.

Run your name through the business entity search on the MiBusiness Registry Portal before you get attached to it, and check the board rules in parallel.

4. The liability shield stops at your own malpractice

This is the most misunderstood point in the entire topic. A Michigan professional company protects you the same way a regular LLC does against business liabilities — the office lease, the equipment loan, a vendor dispute, a slip-and-fall in the waiting room, and the malpractice of your partners and employees that you weren’t personally involved in.

It does not protect you from your own professional negligence. Article 9 preserves personal liability for a licensee’s own wrongful acts. No entity form in Michigan changes that, which is why malpractice insurance is not optional for a licensed practice — the PLLC and the policy do different jobs.

5. Losing your license forces a change

If a member’s license is revoked or lapses such that they’re no longer qualified, that person can no longer hold an ownership interest in the professional company. Your operating agreement should spell out in advance what happens: mandatory transfer of the interest to remaining qualified members, a valuation method, and a payment timeline. Sorting that out on a blank page during a disciplinary proceeding is a bad time.

Filing a Michigan PLLC with LARA

Mechanically, the process closely tracks a standard LLC formation, with a few professional-specific additions.

  1. Confirm your license status. Every organizer and member should be in good standing with their board before filing.
  2. Choose a compliant name including the PLLC designation, and verify availability on the MiBusiness Registry Portal.
  3. File Articles of Organization using LARA’s professional version of the form. The filing states the specific professional service the company will render — that purpose statement is required and is not boilerplate. The filing fee is $50, the same as a standard LLC.
  4. Appoint a resident agent with a Michigan street address (no P.O. boxes).
  5. Add expedited review if you need speed. LARA offers optional 24-hour expedited processing for $50, plus faster tiers at higher prices. Standard turnaround varies by season and filing volume.
  6. Get an EIN. You’ll need one for the practice bank account, payroll, and insurance credentialing. Our EIN filing service handles this if you’d rather not deal with the IRS portal.
  7. Draft an operating agreement with the license-qualification and forced-transfer provisions described above.
  8. Handle board-level registration. Several boards require separate notification or registration of the practice entity — this is a step beyond LARA, and it’s on you to complete.

Annual compliance

Every Michigan LLC and PLLC files an annual statement with LARA by February 15. For a standard LLC the fee is $25; professional companies are billed on LARA’s fee schedule and may be assessed at a different rate, so confirm the current amount when you file rather than assuming.

The consequence of skipping it is the same either way: miss two consecutive years and the state can dissolve your company administratively. For a practice, that’s not just a paperwork problem — a dissolved entity can compromise insurance coverage, contracts, and payer enrollment. We cover the details in our guide to the Michigan annual statement deadline, and our annual statement filing service will handle it on autopilot if you’d rather not track the date.

Frequently asked questions

Can I convert my existing Michigan LLC into a PLLC? Yes. You file a Certificate of Amendment with LARA changing the company name to include the professional designation and adding the required professional purpose statement. If you’ve been operating a licensed practice through a standard LLC, do this sooner rather than later — the amendment is straightforward, and the exposure from waiting isn’t.

Do PLLCs get taxed differently than LLCs in Michigan? No. Federal and Michigan tax treatment is identical — default pass-through taxation, with the same option to elect S corporation status if the numbers justify it. The professional designation is a state entity-law and licensing matter, not a tax classification.

I’m a Michigan-licensed engineer with an unlicensed business partner. What are my options? Your partner cannot be a member of the engineering PLLC. The common workaround is a separate management entity your partner co-owns that provides administrative services, staffing, or facilities to the PLLC under a written contract at fair market rates. Have an attorney structure it — done sloppily, it can read as unlawful fee-sharing.

Does a Michigan PLLC need professional liability insurance? The LLC Act doesn’t impose an insurance requirement as a condition of forming the entity, but individual licensing boards, hospitals, insurers, and clients frequently do. Given that the entity does not shield you from your own malpractice, carrying coverage is a practical necessity regardless of what the statute says.

Can an out-of-state licensed professional own part of a Michigan PLLC? Generally the member must be licensed to render that professional service in Michigan. An out-of-state license alone typically won’t qualify someone to hold an interest — confirm with your board before structuring a multi-state practice.
