A Brief History of the LLC, and Wisconsin's 2023 Rewrite of Chapter 183

If you start a business in the United States in 2026, the odds are overwhelming that you will form a limited liability company. The LLC is now the default. More new entities are formed as LLCs each year than as corporations, partnerships, and every other form combined. That dominance is recent. As late as 1990, the LLC was a regional curiosity that existed in two states. The form's rise from there to ubiquity is one of the more unusual stories in American business law.

Wisconsin's slice of that story matters because the state spent thirty years living with its original 1993 LLC act and then, in 2023, joined twenty-three other states in adopting a uniform-law-based version. If you formed your LLC before 2023, the statute that governs you today isn't quite the one you read at formation. If you formed after, you got the updated chapter by default.

Before the LLC: Two Imperfect Options

For most of the 20th century, an American business owner choosing an entity faced a binary: corporation or partnership. Each had a flaw the other fixed.

• Corporations gave owners limited liability. Creditors of the company could not reach the owners' personal assets. But corporate income was taxed twice: once at the entity level and again when distributed to shareholders as dividends.
• Partnerships were taxed only once, with income flowing through to the partners' individual returns. But partners had unlimited personal liability for partnership debts.

Limited partnerships and S corporations chipped away at this tradeoff in the postwar decades, but each had real constraints. Limited partners lost their liability shield if they participated in management; S corporations had strict eligibility rules (a maximum number of shareholders, U.S.-citizen members only, only one class of stock). None of them fully delivered what owners actually wanted: limited liability and pass-through taxation, with flexible governance, available to anyone.

Wyoming, 1977: The First LLC Statute

The form that solved this was conceived not in a law school but in a Wyoming oil-and-gas office. The Hamilton Brothers Oil Company had been operating overseas through Panamanian limitadas, a civil-law hybrid entity that combined limited liability with partnership tax treatment. The company's American lawyers, looking for a domestic analog, drafted a statute and shopped it to states.

Wyoming enacted the Wyoming Limited Liability Company Act in March 1977, the first LLC statute in the United States. It was a thin document by modern standards, but it had the essential parts: members had limited liability, the entity could be managed by members or by managers, and (the gamble) the drafters expected it to be classified as a partnership for federal tax purposes.

That last point was the catch. The IRS would not commit. For more than a decade, no one knew whether forming a Wyoming LLC would actually achieve pass-through taxation. Adoption stalled. Florida copied the Wyoming act in 1982 and the form sat there as well. Two states, almost no users.

1988: The IRS Says Yes

In 1988, the IRS issued Revenue Ruling 88-76, which held that a Wyoming LLC could be classified as a partnership for federal tax purposes if it lacked enough of the corporate characteristics the regulations cared about (continuity of life, centralization of management, limited liability, and free transferability of interests). That was the unlock.

Once the federal tax answer was clear, the dam broke. Colorado adopted an LLC act in 1990. Eight more states followed in 1991 and 1992. By 1996, every U.S. state and the District of Columbia had an LLC act on the books. The IRS finalized matters in 1997 with the "check-the-box" regulations, which let a multi-member LLC elect partnership or corporate taxation simply by filing a form. Single-member LLCs became disregarded entities by default. The federal tax question was effectively closed.

Wisconsin's Original LLC Act (1993)

Wisconsin enacted its first LLC statute as 1993 Wisconsin Act 112, codified at Chapter 183 of the Wisconsin Statutes. The drafters borrowed from the Wyoming and Florida acts and the early uniform projects then circulating. The 1993 chapter was workable but uneven by modern standards. Heavy on default rules, light on guidance for some recurring problems (member dissociation, fiduciary duty waivers, charging orders, conversions and mergers across entity types).

That chapter remained Wisconsin's LLC law, with periodic amendments, for thirty years. Practitioners learned its quirks. Operating agreements were drafted against its defaults. The DFI and the courts built up a body of guidance interpreting its sections. It worked.

Meanwhile: The Uniform Acts

The Uniform Law Commission (ULC), the body that drafts model statutes for state adoption, published its first attempt at an LLC act in 1996. The original Uniform Limited Liability Company Act (ULLCA) was a reasonable draft but landed during a period when states were busy with their own first-generation LLC acts and were not eager to throw them out. Adoption was thin.

The ULC came back in 2006 with the Revised Uniform Limited Liability Company Act (RULLCA), a substantially better product. RULLCA cleaned up the most contested doctrinal areas. The relationship between the operating agreement and the statute, fiduciary duty defaults and waivability, charging-order exclusivity, dissociation, derivative claims, conversions and domestications. Idaho was first to adopt RULLCA in 2008. By the early 2020s a clear majority of states had adopted RULLCA or a RULLCA-derived act.

Wisconsin took its time. The State Bar of Wisconsin's Business Law Section worked through a Wisconsin adaptation of RULLCA across multiple drafting cycles. The proposed bill was introduced, withdrew, was amended, and was reintroduced. The pandemic delayed it further. It finally crossed the finish line in early 2022.

The 2023 Rewrite: 2021 Wisconsin Act 258

Wisconsin enacted the Wisconsin Uniform Limited Liability Company Law (WULLCA) as 2021 Wisconsin Act 258, signed by Governor Tony Evers on April 15, 2022. The legislative mechanism was a repeal-and-recreate of Chapter 183, which is how Wisconsin typically adopts a uniform act. The practical effect was a comprehensive update: Wisconsin joined the twenty-three states that already had a RULLCA-based statute, with Wisconsin-specific modifications documented in the State Bar of Wisconsin Business Law Section's LLC Committee Report.

The effective dates were staggered:

• January 1, 2023: the new chapter applied to LLCs formed on or after that date automatically. It also applied to LLCs formed before that date unless the LLC filed a "statement of nonapplicability" with the DFI electing to remain under the old chapter.
• The opt-out window had a deadline. After it closed, every Wisconsin LLC fell under the new chapter regardless of when it was formed.

The practical effect: as of 2026, essentially all Wisconsin LLCs are governed by the new chapter. The few that opted out are an edge case.

What Actually Changed in Substance

The update was not just renumbering. Several areas of doctrine moved meaningfully.

What Changed in Numbering

Because Chapter 183 was repealed and recreated rather than amended in place, section numbers shifted. The new chapter is organized into subchapters that follow the RULLCA structure:

• Subchapter I: General Provisions (definitions, scope, operating agreement, knowledge and notice)
• Subchapter II: Formation; Articles of Organization; Names; Registered Agent
• Subchapter III: Relations of Members to Each Other and to LLC (rights, voting, distributions, indemnification)
• Subchapter IV: Relations between LLC and Persons Dealing with LLC (agency, liability)
• Subchapter V: Contributions, Distributions, Capital
• Subchapter VI: Member Dissociation
• Subchapter VII: Dissolution and Winding Up (including the new administrative dissolution section, § 183.0708)
• Subchapter VIII: Foreign LLCs
• Subchapter IX: Derivative Actions
• Subchapter X: Mergers, Conversions, Domestications, Divisions
• Subchapter XI: Miscellaneous

Most concepts from the 1993 chapter survived in some form; the chief structural change was the subchapter organization, which now groups related provisions together (Subchapter VII gathers everything about dissolution and winding up, Subchapter X handles all the cross-entity machinery, and so on). For the operative text of any section, the Wisconsin Legislature's official Chapter 183 page is authoritative.

Should You Review Your Operating Agreement?

If your LLC was formed before 2023 and your operating agreement was drafted against the old chapter, yes. A review is worth doing once. Most pre-2023 agreements still work; courts and counsel are reading them charitably against the new default rules. But three things are worth checking:

1. Statutory citations in your agreement. If the agreement cross-references a specific section (e.g., "in accordance with Wis. Stat. § 183.0103"), confirm that section still says what your agreement assumes. Several were renumbered, and a handful of substantive defaults shifted.
2. Fiduciary duty waivers. The new chapter is more specific about what can and can't be waived. A blanket "members owe no duties beyond those in this agreement" clause may need to be narrowed to fit § 183.0105's nonwaivable list.
3. Dissociation and buyout provisions. The new chapter has a default dissociation regime that didn't exist in the old chapter. If your agreement is silent on dissociation, the new defaults now fill that gap. Which may or may not be what you intended.

None of this is urgent. The new chapter doesn't void existing agreements. But a one-time review by a business attorney, or a careful self-review for a single-member LLC, is sensible hygiene.

Why Any of This Matters for an Owner

You don't need to know the history of the LLC to run one. But the 2023 update is one of those silent changes that affects you whether you noticed or not. Your LLC is now governed by an updated chapter with modestly revised default rules, a different section-numbering scheme, and a cleaner conceptual structure modeled on RULLCA. Two concrete consequences for owners:

• If you have a creditor problem, the charging-order-exclusivity rule in the new chapter is stronger than what the prior chapter explicitly provided. That's an upgrade for owners and a downgrade for personal creditors.
• If you're contemplating a conversion, domestication, or merger: turning your LLC into a corporation, redomesticating from another state, or combining with a related entity. Subchapter X gives you procedural tools the 1993 chapter didn't have. The transactions are cleaner.

The LLC turns 49 in 2026. It started as a Wyoming oil-company workaround for the Panamanian limitada and became the dominant American business entity in less than a generation. Wisconsin's 2023 update is one more iteration in that arc, bringing the state's statute in line with the modern uniform model that most of the country now uses.
