Key Takeaways
- Wisconsin does NOT offer a PLLC as a distinct entity type — Wisconsin Statutes Chapter 183 (the Uniform LLC Law, 2021 Act 258, effective April 15, 2022) contains no professional-LLC subchapter at all — Wisconsin simply doesn't offer a "PLLC" as a distinct entity type. The professional-entity structure instead lives in Chapter 180, Subchapter XIX (§§180.1901-180.1921), which creates a "Service Corporation" ("S.C.") — Wisconsin's term for what most states call a professional corporation. Importantly, Wisconsin does not funnel licensed professionals into the S.C. as their only alternative either. Attorneys specifically get a genuine three-way choice under Wisconsin Supreme Court Rule SCR 20:5.7: a law practice may operate as a plain LLC, an LLP, or an S.C., with annual State Bar registration and proof of malpractice insurance required regardless of which entity is chosen. Other licensed professions should confirm with their own board whether the same flexibility applies to them, but the key point is that Wisconsin genuinely does not require a separate professional entity type the way most PLLC states do.
- Wisconsin does not require licensing board pre-approval as a condition of filing
- Not broadly available. The clearest cross-license flexibility identified is the CPA-firm exception to the Service Corporation's otherwise-strict same-profession shareholder rule. Outside of that, Wisconsin professionals generally can't combine different licensed professions under one entity, whether that entity is an S.C., LLC, or LLP.
- LLC Attorney does not form PLLCs or other professional entities — this guide is educational; where your profession permits a standard LLC or corporation, LLC Attorney can form that
Wisconsin doesn't offer a PLLC as a distinct entity type — Chapter 183's LLC Law contains no professional-LLC subchapter at all. Instead, licensed professionals choose among a plain LLC, an LLP, or a Service Corporation (S.C.) depending on their specific profession's rules.
This guide covers exactly what Wisconsin licensed professionals use instead of a PLLC in 2026 — the genuine three-way choice attorneys have under SCR 20:5.7, how the Service Corporation route works for other professions, filing costs through the Department of Financial Institutions, and what liability protection each structure actually provides.
What Is a Wisconsin PLLC?
A Professional Limited Liability Company (PLLC) is a special LLC designation for licensed professionals — doctors, lawyers, accountants, and similar occupations. It works like a regular LLC, but ownership is restricted to people who hold the same professional license, and formation often requires sign-off from your licensing board before the state will accept your filing.

Who Needs a PLLC in Wisconsin?
No profession is required to use a PLLC in Wisconsin, because the entity type doesn't exist here. Licensed professionals instead choose among a plain LLC, an LLP, or a Service Corporation (S.C.) depending on their profession's own rules — confirmed concretely for attorneys under SCR 20:5.7, who may practice through any of the three.
Attorneys are the clearest confirmed example: under Wisconsin Supreme Court Rule SCR 20:5.7, a law practice may be organized as a plain LLC, an LLP, or a Service Corporation, with annual State Bar registration and proof of malpractice insurance required no matter which entity is chosen. Other licensed professions should verify with their own licensing board whether the same three-way flexibility applies, since Wisconsin doesn't have a single uniform rule across every profession.
Who Can Own a Wisconsin PLLC?
For a Service Corporation, all shareholders must be natural persons, and each shareholder must be licensed, certified, or registered in the same profession named in the Articles — with two notable exceptions: CPA firms are not required to have 100% licensed shareholders, and a sole-shareholder S.C. has its own exception under §180.1921(2). For attorneys using an LLC or LLP instead of an S.C., Wisconsin Supreme Court Rule SCR 20:5.4(d) bars any nonlawyer ownership regardless of entity type.
Not broadly available. The clearest cross-license flexibility identified is the CPA-firm exception to the Service Corporation's otherwise-strict same-profession shareholder rule. Outside of that, Wisconsin professionals generally can't combine different licensed professions under one entity, whether that entity is an S.C., LLC, or LLP.
What Liability Protection Does a PLLC Actually Provide?
A PLLC protects you from business debts and from a co-owner's malpractice — but it never shields you from your own malpractice. If you personally provide negligent professional services, you remain personally liable for that regardless of the entity structure.
Regardless of whether you choose a plain LLC, LLP, or Service Corporation, a Wisconsin licensed professional remains personally liable for their own malpractice — the entity shields against ordinary business debts and, in most structures, a co-owner's negligence, but never your own negligent professional acts.
Confirmed for attorneys specifically: Wisconsin Supreme Court Rule SCR 20:5.7 requires annual State Bar registration with proof of malpractice insurance, regardless of which entity type (LLC, LLP, or S.C.) the law practice uses. This isn't confirmed as a universal cross-profession statutory mandate for every Service Corporation — other professions should check their own board's rules.
How Is a Wisconsin PLLC Taxed?
By default, a PLLC is taxed exactly like a regular LLC — pass-through to the owners' personal returns, with the option to elect S-corp or C-corp taxation if that fits your situation better. The professional designation changes ownership eligibility and licensing oversight, not the default federal tax treatment.
Wisconsin's individual income tax is graduated from 3.50% to 7.65% for 2026, with the top rate applying above $315,310 (single) or $420,420 (married filing jointly) of taxable income — pass-through profit from an LLC, LLP, or S.C. electing pass-through treatment is taxed at these rates on the owners' personal returns.
Wisconsin LLCs and Service Corporations both owe an annual report fee — $25 online or $40 by mail — due by the end of the quarter of the entity's formation anniversary. Delinquency after three consecutive missed years triggers administrative dissolution.
Wisconsin is one of two states in this batch (along with Wyoming) with no PLLC at all, but the details differ meaningfully: Wisconsin routes professionals into a genuinely named alternative entity (the Service Corporation) rather than simply letting them use a plain LLC as Wyoming does — though Wisconsin does still permit plain LLCs and LLPs for some professions, like attorneys.
How to Set Up Your Wisconsin PLLC Step by Step
If You Do It Yourself
Step 1 — Confirm you need a PLLC (not a plain LLC) for your profession.
No profession is required to use a PLLC in Wisconsin, because the entity type doesn't exist here. Licensed professionals instead choose among a plain LLC, an LLP, or a Service Corporation (S.C.) depending on their profession's own rules — confirmed concretely for attorneys under SCR 20:5.7, who may practice through any of the three.
Step 2 — Get licensing board sign-off if required.
For the Service Corporation route, no blanket Department of Financial Institutions (DFI) pre-approval gate has been identified beyond the Articles of Incorporation's own required certifications — incorporators self-certify that all shareholders, directors, and officers are licensed in the designated field. For attorneys choosing to practice through an LLC instead, there's no pre-filing board approval either; the requirement is an annual State Bar registration with proof of malpractice insurance, which is a recurring compliance step rather than a one-time pre-filing gate. Because Wisconsin doesn't gate either the LLC or S.C. filing behind licensing-board pre-approval, your entity can be formed as soon as DFI accepts your Articles. Just remember the S.C.'s self-certification language must be included in your Articles of Incorporation, and if you're an attorney choosing an LLC or LLP, register annually with the State Bar and keep your malpractice insurance proof current.
Step 3 — File your formation documents.
Wisconsin Statutes Chapter 183 (the Uniform LLC Law, 2021 Act 258, effective April 15, 2022) contains no professional-LLC subchapter at all — Wisconsin simply doesn't offer a "PLLC" as a distinct entity type. The professional-entity structure instead lives in Chapter 180, Subchapter XIX (§§180.1901-180.1921), which creates a "Service Corporation" ("S.C.") — Wisconsin's term for what most states call a professional corporation. Importantly, Wisconsin does not funnel licensed professionals into the S.C. as their only alternative either. Attorneys specifically get a genuine three-way choice under Wisconsin Supreme Court Rule SCR 20:5.7: a law practice may operate as a plain LLC, an LLP, or an S.C., with annual State Bar registration and proof of malpractice insurance required regardless of which entity is chosen. Other licensed professions should confirm with their own board whether the same flexibility applies to them, but the key point is that Wisconsin genuinely does not require a separate professional entity type the way most PLLC states do.
Step 4 — Appoint a registered agent.
Wisconsin calls this role a "Registered Agent" — required at formation.
Step 5 — Confirm ownership eligibility for every member.
For a Service Corporation, all shareholders must be natural persons, and each shareholder must be licensed, certified, or registered in the same profession named in the Articles — with two notable exceptions: CPA firms are not required to have 100% licensed shareholders, and a sole-shareholder S.C. has its own exception under §180.1921(2). For attorneys using an LLC or LLP instead of an S.C., Wisconsin Supreme Court Rule SCR 20:5.4(d) bars any nonlawyer ownership regardless of entity type.
Step 6 — Address malpractice insurance requirements.
Confirmed for attorneys specifically: Wisconsin Supreme Court Rule SCR 20:5.7 requires annual State Bar registration with proof of malpractice insurance, regardless of which entity type (LLC, LLP, or S.C.) the law practice uses. This isn't confirmed as a universal cross-profession statutory mandate for every Service Corporation — other professions should check their own board's rules.
Step 7 — Handle ongoing state compliance.
Wisconsin LLCs and Service Corporations both owe an annual report fee — $25 online or $40 by mail — due by the end of the quarter of the entity's formation anniversary. Delinquency after three consecutive missed years triggers administrative dissolution. Wisconsin's individual income tax is graduated from 3.50% to 7.65% for 2026, with the top rate applying above $315,310 (single) or $420,420 (married filing jointly) of taxable income — pass-through profit from an LLC, LLP, or S.C. electing pass-through treatment is taxed at these rates on the owners' personal returns.
Step 8 — Watch for Wisconsin-specific PLLC traps.
The most common Wisconsin-specific mistake is assuming every licensed professional must use the Service Corporation — in reality, Wisconsin's rule varies by profession, and attorneys specifically have a confirmed right to use a plain LLC or LLP instead, so don't default to the more complex S.C. structure without first checking whether your profession allows a simpler option.

When Should You Talk to an Attorney About Your Wisconsin PLLC?
Talk to an attorney before choosing your Wisconsin entity structure if you're not sure whether your profession is confined to the Service Corporation route or has the same three-way flexibility attorneys enjoy, if you're forming a CPA firm and want to use the shareholder-licensing exception, or if you need help drafting the self-certification language a Service Corporation's Articles of Incorporation must include.
Is Wisconsin a State Where PLLC Formation Is More Complex?
Wisconsin is more complex than most states because there's no single, unified answer to "what should a licensed professional use instead of a PLLC." The answer depends on your specific profession and its governing board: attorneys get an explicit three-way choice (LLC, LLP, or S.C.) under SCR 20:5.7, while other professions may face a narrower Service Corporation requirement under Chapter 180's Subchapter XIX. Confirm your specific profession's rule before assuming any one structure applies uniformly.

Frequently Asked Questions
No. Wisconsin does not offer a PLLC as a distinct entity type. Licensed professionals instead choose among a plain LLC, an LLP, or a Service Corporation (S.C.) under Wis. Stat. §§180.1901-180.1921, depending on what their specific profession's governing rules allow.
No profession is required to use a PLLC in Wisconsin since it doesn't exist here. Attorneys have a confirmed three-way choice among plain LLC, LLP, or Service Corporation under SCR 20:5.7; other licensed professions should confirm their own board's rule, since some may be confined to the Service Corporation route.
No blanket pre-approval gate exists for either route. Service Corporations self-certify licensure status directly in their Articles of Incorporation, and attorneys choosing an LLC or LLP register annually with the State Bar rather than obtaining pre-filing board approval.
A Wisconsin LLC costs $130 online or $170 by mail to form; a Service Corporation costs approximately $100 through the Department of Financial Institutions.
For a Service Corporation, all shareholders must be natural persons licensed in the same profession, except CPA firms (which aren't required to have 100% licensed shareholders) and certain sole-shareholder arrangements. For attorneys using an LLC or LLP, no nonlawyer may hold an ownership interest.

Regardless of whether you choose a plain LLC, LLP, or Service Corporation, a Wisconsin licensed professional remains personally liable for their own malpractice — the entity only shields against ordinary business debts and, in most structures, a co-owner's negligence.
