A Michigan PLLC, or Professional Limited Liability Company, is the entity licensed professionals in Michigan use to practice together while shielding personal assets from most business debts. Forming one takes a $50 filing with the Michigan Department of Licensing and Regulatory Affairs (LARA), a licensed membership, and a commitment to annual filings that are stricter than what a standard LLC faces. Miss those obligations and you can lose good standing, or lose the liability protection you formed the company to get.
Who Can Be a Member
Only licensed professionals can organize a Michigan PLLC or hold a membership interest in one. Every member and every manager has to be licensed in at least one of the professional services the company provides.1Michigan Legislature. Michigan Compiled Laws 450.4904 – Rendering Professional Services Someone without a license can’t own a piece of the company, can’t manage it, and can’t control its professional work.
Michigan carves out a narrow exception for related medical fields. Physicians, osteopathic physicians, chiropractors, and podiatrists can form a single PLLC together, and physician assistants can join those PLLCs under certain conditions. Outside that carve-out, every member of a health-care PLLC has to be licensed in the same profession.1Michigan Legislature. Michigan Compiled Laws 450.4904 – Rendering Professional Services A professional licensed in another state can become a member, but can’t render professional services in Michigan until they get a Michigan license.
Filing the Articles of Organization
Formation begins with filing Articles of Organization at LARA. Most professions use the standard LLC form. Doctors, osteopathic physicians, surgeons, dentists, clergy, and attorneys have to use a separate PLLC form (CSCL/CD-701).2Michigan Department of Licensing and Regulatory Affairs. Articles of Organization for Domestic Limited Liability Companies Either way, the filing fee is $50.3Michigan Department of Licensing and Regulatory Affairs. Filing Fees
The articles have to state that the company is formed to render specified professional services.4Michigan Legislature. Michigan Compiled Laws 450.4903 – Professional Limited Liability Company They also have to name a registered agent with a physical Michigan address who can accept legal documents on the company’s behalf.
Naming the Company
The legal name has to include “Professional Limited Liability Company” or an approved abbreviation: P.L.L.C. or P.L.C. Periods are optional, so PLLC and PLC work too.4Michigan Legislature. Michigan Compiled Laws 450.4903 – Professional Limited Liability Company The name also has to be distinguishable from every other entity on file with LARA. Run a search on LARA’s business entity lookup before you file, or you’ll pay for a rejection.
Getting an EIN
Once the PLLC exists, apply for a federal Employer Identification Number from the IRS. You’ll need it to open bank accounts, hire employees, and file tax returns. Applying online is free, or you can submit Form SS-4.5Internal Revenue Service. About Form SS-4, Application for Employer Identification Number If the responsible party for the EIN changes later, report it to the IRS within 60 days on Form 8822-B.
The Operating Agreement
Michigan doesn’t require a PLLC to have a written operating agreement. Operating without one, though, means the default provisions of the Michigan Limited Liability Company Act govern every internal question, from profit splits to what happens when a member leaves.
A useful operating agreement covers:
- Management structure. Are all members involved in daily decisions (member-managed), or do you appoint designated managers (manager-managed)?
- Voting rights. Michigan’s default gives each member one vote regardless of ownership percentage. If you want votes tied to capital contributions or another formula, the agreement has to say so.6Michigan Legislature. Michigan Compiled Laws 450.4502 – Members Voting Rights
- How profits and losses are allocated among members.
- How new licensed professionals are admitted and how departures, retirements, or deaths are handled.
- How internal disputes get resolved: mediation, arbitration, or litigation.
Certain major decisions belong to the members no matter what the operating agreement says. Dissolution, mergers, amendments to the articles, and entity conversions can only be authorized by members, not by managers.6Michigan Legislature. Michigan Compiled Laws 450.4502 – Members Voting Rights
Annual Filings and Staying in Good Standing
PLLCs carry heavier annual obligations than ordinary Michigan LLCs. Every year by February 15, a PLLC has to file a combined Annual Statement and Annual Report with LARA and pay a $75 fee.7Michigan Department of Licensing and Regulatory Affairs. Limited Liability Company Filing Information The report has to list the names and addresses of every member and manager and certify that each one holds a current professional license.8Michigan Legislature. Michigan Compiled Laws 450.4909 A PLLC formed after September 30 doesn’t have to file on the immediately following February 15.
Miss February 15 and a $50 late penalty stacks on top of the filing fee.8Michigan Legislature. Michigan Compiled Laws 450.4909 Skip two consecutive years and LARA sends a notice. You then have 60 days to catch up on every missing report, fee, and penalty. After that window, the PLLC loses good standing. That means no certificate of good standing, your company name becomes available for someone else to claim, and LARA won’t accept any other filings from you until you fix it. The company doesn’t automatically dissolve, but operating without good standing creates problems with banks, clients, and licensing boards.
Each member also has to keep their own professional license current: continuing education, renewal fees, and compliance with the relevant Michigan board. If a member’s license lapses, they can no longer render professional services through the PLLC.
What the PLLC Can and Can’t Do
A Michigan PLLC is limited to providing the professional services specified in its articles of organization.9Michigan Legislature. Michigan Compiled Laws 450.4907 A law PLLC can’t run a side consulting practice. A medical PLLC can’t offer financial planning.
Mergers are restricted too. A PLLC can only merge with entities whose owners are all licensed professionals eligible to be members of the PLLC.10Michigan Legislature. Michigan Compiled Laws 450.4910 – Merger Limitation A law PLLC can’t merge with an accounting firm unless every owner on both sides holds the necessary licenses.
The same restriction applies to ownership transfers. Membership interests can only be sold or transferred to someone eligible to be a member, meaning another licensed professional in the same field. The narrow exception covers the estate of a deceased or legally incapacitated member, which can hold the interest temporarily but can’t participate in professional-service decisions.11Michigan Legislature. Michigan Compiled Laws 450.4908 – Sale or Transfer of Membership Interest
Liability Protection and Where It Stops
The PLLC shields each member’s personal assets from the company’s general business debts and contract obligations. If the company can’t pay a lease or gets sued by a vendor, creditors generally can’t reach a member’s personal accounts or property.
The shield stops at professional malpractice. If you commit malpractice while treating a patient, advising a client, or designing a structure, you’re personally liable for that claim. The PLLC doesn’t insulate you from the consequences of your own professional mistakes. Other members who weren’t involved in the negligent act are typically protected from that particular claim.
How the Shield Gets Broken
Michigan courts can disregard the PLLC and hold members personally liable for business debts when the company was run as a shell. The behaviors that invite this outcome are familiar: mixing personal and business funds, failing to keep separate books, undercapitalizing the business at formation, and skipping basic formalities like annual filings and operating-agreement provisions.
Depositing client payments into a personal account, missing annual reports, or generally treating the PLLC as if it doesn’t exist gives a court reason to make members personally responsible for the company’s debts. Respecting the PLLC as a genuinely separate entity in every financial and administrative decision is the best defense.
How a PLLC Is Taxed
The IRS treats a PLLC like any other LLC. A single-member PLLC is a disregarded entity by default, with income flowing onto the owner’s personal return (usually Schedule C). A multi-member PLLC is treated as a partnership, and profits and losses pass through to each member’s individual return.12Internal Revenue Service. Limited Liability Company (LLC) Neither triggers corporate-level tax.
A PLLC can elect different treatment on Form 8832, choosing to be taxed as a C corporation, or, with a separate election on Form 2553, as an S corporation.13Internal Revenue Service. About Form 8832, Entity Classification Election The right choice depends on member income levels, compensation structure, and self-employment tax exposure. For most smaller PLLCs the default pass-through treatment is simplest; higher-earning practices sometimes benefit from an S corporation election that can reduce self-employment tax on distributions.
Michigan Corporate Income Tax
A PLLC that elects to be taxed as a C corporation becomes subject to Michigan’s 6% Corporate Income Tax. A small business alternative credit offers a reduced 1.8% rate on adjusted business income for qualifying companies.14State of Michigan. Corporate Income Tax PLLCs taxed as pass-through entities (the default) aren’t subject to the CIT because the income is reported on members’ personal returns instead.
The Section 199A Deduction Has Expired
Through the 2025 tax year, the Section 199A qualified business income deduction let eligible pass-through owners deduct up to 20% of their qualified business income. The deduction expired for tax years beginning after December 31, 2025.15Internal Revenue Service. Qualified Business Income Deduction Congress may extend or revive it, but as of early 2026, PLLC members can’t count on it without new legislation. The change could meaningfully raise the effective tax rate on pass-through PLLC income, so the choice between pass-through and corporate treatment is worth revisiting with a tax advisor.
Insurance
Because the PLLC doesn’t protect members from their own malpractice, professional liability insurance isn’t optional in any practical sense. Medical professionals need medical malpractice policies. Attorneys need legal malpractice coverage. Engineers and architects carry professional errors and omissions insurance. Some Michigan licensing boards set minimum coverage levels, so check with your board before assuming your current limits are enough.
General liability insurance covers what happens outside professional services: a client slipping in the lobby, property damage during office renovations, and similar incidents. Any PLLC with a physical office or client-facing operations should carry it.
Cyber liability insurance matters for firms that handle sensitive data. Medical records, legal case files, and financial documents are attractive targets. A cyber policy covers breach response, notification, forensic investigation, regulatory penalties, and third-party claims. For professions with confidentiality obligations enforced by licensing boards, a breach can trigger both civil liability and ethics complaints.
What About Beneficial Ownership Reporting
The Corporate Transparency Act originally required most domestic companies, including PLLCs, to report beneficial ownership information to the Financial Crimes Enforcement Network. In March 2025, FinCEN issued an interim final rule exempting every entity created in the United States from those reporting requirements. FinCEN also said it will not enforce beneficial ownership reporting penalties against U.S. citizens or domestic companies.16FinCEN. Beneficial Ownership Information Reporting Only entities formed under foreign law and registered to do business in the U.S. still have to file. Michigan PLLCs don’t currently need to file a BOI report, though that could change through future rulemaking.
