How to Form a Professional LLC in Michigan

Here are the basic rules for forming professional limited liability companies in Michigan.



As a licensed professional in Michigan you can structure your business as a Michigan professional limited liability company (PLLC). This will give you protection from several important types of liability. It also may provide certain tax advantages compared to other ways of structuring your business.

What is a Michigan PLLC?

A Michigan PLLC is a limited liability company (LLC) formed specifically by people who will provide Michigan licensed professional services. LLCs in general are businesses registered with the state that consist of one or more people—called LLC members—who own the business. Like other LLCs, PLLCs protect their individual members from people with claims for many (but not all) types of financial debts or personal injuries. (Note: Michigan law sometimes refers to PLLCs as professional service limited liability companies rather than just professional limited liability companies.)

What is a Professional Service?

Under Michigan’s LLC Act, professional services include services performed by:

  • certified or other public accountants
  • chiropractors
  • dentists
  • optometrists
  • veterinarians
  • osteopathic physicians
  • physicians
  • surgeons
  • podiatrists
  • chiropodists
  • physician's assistants
  • architects
  • professional engineers
  • land surveyors, and
  • attorneys.

If you are licensed to practice one of these professions in Michigan you can form a Michigan PLLC. More generally, any person who is required by state law to have a Michigan license or other legal authorization before providing professional services should be able to form a Michigan PLLC for those services.

How Do I Form a Michigan PLLC?

To form your Michigan PLLC you’ll need to:

  • have the state license for each professional who will be a member of the company, and
  • check with the state licensing board for your profession to see if its prior approval is required, (and, if so, obtain the necessary documentation showing that approval), and
  • file articles of organization with the Michigan Department of Licensing and Regulatory Affairs (LARA) that include a statement of the professional service or services the PLLC will provide.

You can download a blank articles of organization form (Form CSCL/CD-701), which is specifically for PLLCs (as opposed to standard LLCs), by going to the LARA website.   The form is in PDF format and you can type in the required information on your computer (you will have to print it out in order to sign it).   The current filing fee for the articles of organization is $50. You can articles file by email or mail.  

Naming Restrictions

Michigan requires that your PLLC contain the words "professional limited liability company," or the abbreviation "P.L.L.C." or "P.L.C." with or without periods or other punctuation. For additional important information on LLC names, check the  Business Name, Location & Licenses  section of the Nolo website.

Service and Membership Restrictions

In general, a Michigan PLLC can provide professional services in more than one profession if doing so isn’t otherwise prohibited by state law. In such cases, each PLLC member or manager must be licensed in at least one of the professional services rendered by the company. However, special rules and restrictions apply to PLLCs that:

  • render professional services that are included within Michigan’s public health code
  • render professional services including the practices of medicine, osteopathic medicine and surgery, and podiatric medicine and surgery
  • engage in in the practice of architecture, professional engineering, and/or professional surveying , and
  • engage in the practice of public accounting.

More generally, Michigan PLLCs and/or their members are subject to the regulation of the relevant state professional licensing authorities.

Operating Agreement

You should make sure you have an operating agreement for your PLLC. Unlike professional licenses, the certificate of organization, and naming and service restrictions, this is not a state requirement. However, it is important to have an operating agreement so that other members of the PLLC (if any), as well as outside companies and businesses (for example banks), know what the internal rules are for your business. Depending on your own level of knowledge and expertise, you should consider having a lawyer assist you in preparing this document.

A PLLC Will Not Protect You From All Liability

Forming your professional service business as a PLLC will protect you personally from:

  • creditors seeking to collect unpaid debts owed solely by the PLLC
  • liability for the malpractice of other PLLC members (technically known as “vicarious liability”), and
  • people who are personally injured in connection with your PLLC because of things having nothing to do with your own professional malpractice or torts (for example, if someone slips and falls in your PLLC’s offices).

Regarding protection from liability for the malpractice of fellow PLLC members, be aware that, for some professions in some states, PLLC members are required to have a minimum amount of malpractice insurance before they are eligible for such protection.   Therefore, it’s always a good idea to double check your state’s PLLC laws, as well as your state’s rules for your particular profession, regarding minimum insurance requirements.

Meanwhile, you are personally responsible if:

  • you personally guarantee repayment of a business loan
  • you engage in professional malpractice (such as completely botching a patient’s treatment or egregiously mishandling a client’s case), or
  • you intentionally or negligently commit a tort (such as assaulting someone).

Because you are not protected from your own malpractice, you should make sure you have professional liability insurance—and, if applicable, that your coverage meets any minimum insurance requirements.

A PLLC Different From a Professional Corporation

A PLLC is not the same thing as a professional corporation (PC). A PLLC is a newer type of business entity than a PC. Here are some of the key differences:

  • a PLLC, like other LLCs, is comprised of members, but a PC, like other corporations, is comprised of shareholders
  • following from the previous point, PLLC ownership consists of so-called membership interests in the business, but PC ownership is based on shares of stock; and
  • a PLLC, like other LLCs, is a so-called pass-through tax entity, meaning that in most states (including Michigan) only the individual members have income tax obligations, while a PC, like other corporations, usually has its own income tax obligations.

The tax differences between PLLCs and PCs can become complicated. For example, a PC can elect a special tax status (S corporation status) that effectively makes it a pass-through tax entity like a PLLC. And, meanwhile, PCs that don’t elect special status may be subject to  double taxation—in other words, both the PC itself and its shareholders may have to pay taxes on business income.

Michigan allows professionals to form both PLLCs and PCs, and both PLLCs and PCs provide liability protection for, respectively, their members or shareholders. Because the protection is essentially the same for both PLLCs and PCs, but PLLCs are simpler to create and operate, many professionals prefer the PLLC structure.
