Forming a Professional Service Corporation (S.C.) in Wisconsin for Licensed Professionals

When licensed professionals decide to open a practice in Wisconsin, standard business structures often do not apply. State law strictly regulates how doctors, dentists, lawyers, and accountants can incorporate. To maintain professional standards and accountability, the state created the Professional Service Corporation, commonly abbreviated as S.C. (Service Corporation).

If you are opening a clinic in Madison, a law firm in Milwaukee, or an accounting practice in Green Bay, selecting the correct entity type is mandatory. Forming an S.C. not only complies with state law but also provides crucial liability shields. Navigating the regulatory requirements of both the state and your specific licensing board can be complex.

Why Form a Professional Service Corporation (S.C.) in Wisconsin?

The primary advantage of an S.C. is specialized liability protection. Under Wis. Stat. § 180.1915, while no business structure can protect you from your own malpractice, an S.C. ensures that you are not personally liable for the negligence or malpractice committed by your partners or employees. The precedent set in Anderson v. McBurney, 160 Wis. 2d 866 (WI Court of Appeals 1991) emphasizes the boundaries of personal liability among shareholders operating within a professional service corporation.

Medical and Dental Practices

Physicians and dentists face high risks of malpractice claims. By forming an S.C., a doctor is shielded if another doctor in the same practice makes a critical error. Only the assets of the corporation and the specific physician at fault are at risk.

Law Firms

Attorneys dealing with high-stakes litigation or real estate transactions often form S.C. entities. The Wisconsin Supreme Court has specific rules regarding how law firms must be structured to ensure ethical duties to clients are maintained, while still allowing partners to protect their personal homes and savings.

CPA Firms

Certified Public Accountants dealing with audits and tax compliance utilize the S.C. structure to separate personal wealth from professional liability, especially when multiple accountants are sharing office space and resources.

Key Statutory Requirements in Wisconsin

Operating an S.C. means adhering to a very specific set of rules found in Chapter 180 of the state statutes.

Strict Naming Conventions

Under Wis. Stat. § 180.1907, your corporate name must clearly indicate its professional nature. The business name must end with 'Service Corporation', 'Chartered', or the abbreviation 'S.C.'. You cannot use generic designators like 'Inc.' or 'LLC' without authorization.

Ownership Restrictions

Unlike a standard corporation where anyone can buy stock, Wis. Stat. § 180.1911 mandates that all shareholders, directors, and officers in a Service Corporation must be licensed to practice the same profession within the state. A doctor cannot own shares in an attorney's S.C., and an unlicensed investor cannot own shares in a dental practice.

Filing the Correct Paperwork

To establish the entity, you must file Form 2, Wisconsin, Department of Financial Institutions, Articles of Incorporation - Business Corporation with the Wisconsin Department of Financial Institutions, Madison. This form requires you to state the specific professional service the corporation will provide, and you may need to provide proof of current state licenses.

Costs and Timelines

The state filing fee for submitting Form 2 is $100. If you require expedited processing, an additional $100 fee applies. Standard processing online typically takes a few business days. However, because professional corporations require meticulously drafted bylaws and shareholder agreements to handle scenarios like a partner losing their license or retiring, legal fees generally range from $1,500 to $4,000 depending on the size of the practice.
