The History of the LLC — Wyoming, 1977

Every LLC formed anywhere in the United States today traces back to one statute, in one state, in 1977. This is that history, told from the jurisdiction that wrote it. Not legal advice.

1977: Wyoming writes the first LLC statute

The Wyoming Limited Liability Company Act — Wyo. Stat. Ann. §17-29-101 et seq. — was enacted in 1977, per the sitewide statute-adoption-timeline matrix's Wyoming row. No other state had anything like it yet: the LLC — a business form combining a corporation's liability shield with a partnership's pass-through tax treatment — did not exist as a US legal category before this. In my own read, this is the real headline of Wyoming's LLC history: not that Wyoming has good LLC law today, but that the entity type itself is a Wyoming invention.

Eleven years in federal tax limbo

A state can write whatever business-entity statute it wants; it cannot, by itself, decide how the IRS taxes that entity. Under the IRS's then-governing Kintner regulations, an entity was taxed as a corporation if it had enough corporate-like characteristics — limited liability among them — regardless of what a state statute called it. That left Wyoming's new LLC in a genuine gray zone: liability protection without a settled answer on whether the IRS would tax it as the pass-through entity its drafters intended, or as a corporation. Other states had little reason to adopt a business form whose core tax benefit was unconfirmed, and for the next eleven years, almost none did.

1988: Revenue Ruling 88-76 ends the uncertainty

The IRS resolved the question in 1988 with Revenue Ruling 88-76: a Wyoming LLC would be classified and taxed as a partnership, not a corporation, for federal income tax purposes. That single ruling answered the question every other state's legislature had been waiting on — an LLC really could deliver both liability protection and pass-through taxation at once, not one or the other.

1982 to 1994: the rest of the country catches up

Only one other state moved before the ruling: Florida, in 1982, per the same statute-adoption-timeline matrix — a genuine early follower during the eleven-year limbo window, not a post-ruling adopter. Everyone else waited. Once Revenue Ruling 88-76 settled the federal tax question, adoption accelerated fast: Colorado and Kansas in 1990; Utah and Virginia in 1991; a cluster of eight more — Iowa, Illinois, Louisiana, Maryland, Minnesota, Oklahoma, Rhode Island, West Virginia — in 1992; the largest single-year cluster, fifteen states including Georgia, Indiana, Michigan, and Wisconsin, in 1993; and a final wave of nine, including California, New York, and Pennsylvania, in 1994. That is 38 states this site has independently confirmed an enactment year for, sourced state by state to each one's own statute text.

Thirteen states — Alabama, Arizona, Arkansas, Delaware, Hawaii, Massachusetts, Mississippi, Nevada, New Hampshire, South Dakota, Tennessee, Texas, and Vermont — are not named with a specific year here, on purpose. Each adopted an LLC statute during roughly this same window, but this site has not yet independently confirmed the exact enactment year against a source meeting its own citation standard for every one of them; asserting a year without that confirmation would be exactly the kind of claim the underlying matrix is built to avoid making.

Wyoming keeps legislating first

The 1977 act was not a one-time first. Wyoming was also the first state to let an LLC elect Decentralized Autonomous Organization (DAO) status by statute, in 2021 — a dedicated supplement (Wyo. Stat. §§17-31-101 to 17-31-116) with its own election mechanism, not an informal reading of general LLC flexibility. The fuller catalog of where Wyoming has built statutory options other states have not — Close LLC, Series LLC, DAO LLC, and more — lives on the entity statutes page, not repeated here. The throughline from 1977 to now, in my own read: Wyoming treats LLC law as something to keep building, not a form it wrote once and left alone.

What this essay does not prove

• “First” is a statutory claim, not a claim about every practical detail. Other states may have had informal or partial precursors to LLC-like structures before 1977; this essay tracks the first STATUTE creating the LLC as a named business form, per the matrix's own field definition.
• The 13 unconfirmed states are a research gap, not a claim that they adopted later or earlier than they did. Leaving a state's year out here says nothing about when it actually adopted — only that this site has not yet cleared its own citation bar for that specific year.
• This is a statutory and tax-classification history, not a full legislative or case-law history. It does not track amendments, recodifications, or the litigation history of any state's LLC act beyond the enactment year itself.
