Louisiana Business Entity Law: LLCs, Corporations, and Partnerships

Louisiana's legal framework for business entities operates under a hybrid system that blends civil law traditions with statutory structures closely tracked to uniform commercial models adopted across other U.S. states. The Louisiana Revised Statutes govern the formation, operation, and dissolution of limited liability companies, corporations, and partnerships, with distinct title provisions applying to each entity type. Practitioners, entrepreneurs, and researchers navigating entity selection, governance obligations, or dissolution procedures must engage directly with these statutory frameworks and the regulatory authority of the Louisiana Secretary of State. The Louisiana Legal Services Authority home provides orientation to the broader legal landscape within which these business law provisions operate.

Definition and scope

Business entity law in Louisiana defines the legal structures through which persons — natural or juridical — may organize for commercial, professional, or investment activity. The three primary organizational categories are the limited liability company (LLC), the corporation, and the partnership, each governed by separate statutory titles within the Louisiana Revised Statutes.

• Limited Liability Companies are governed by the Louisiana Limited Liability Company Law, codified at La. R.S. 12:1301 et seq. An LLC offers members limited liability protection while permitting pass-through federal taxation by default. Louisiana requires at least 1 member and mandates filing of Articles of Organization with the Secretary of State.
• Corporations are governed by the Louisiana Business Corporation Act, La. R.S. 12:1-101 et seq., enacted in 2014. Corporations issue shares, are managed by a board of directors, and are treated as juridical persons capable of holding property, contracting, and suing. Louisiana imposes an annual report obligation and franchise tax administered by the Louisiana Department of Revenue.
• Partnerships fall under two distinct forms under Louisiana civil law: the general partnership (société en nom collectif) and the limited partnership, governed by La. R.S. 9:3401 et seq. and the Louisiana Uniform Limited Partnership Law respectively. General partners bear unlimited personal liability; limited partners' exposure is capped at their contribution.

Scope limitations: This page addresses entity types organized under Louisiana state law. It does not cover entities formed in other jurisdictions that merely register as foreign entities to do business in Louisiana, federal tax classification decisions made through IRS Form 8832 or Schedule C elections, or securities law compliance under the Louisiana Securities Law (La. R.S. 51:701 et seq.). For regulatory and compliance dimensions intersecting with state administrative bodies, see the regulatory context for Louisiana's legal system.

How it works

Formation

1. Name reservation and availability check — The Louisiana Secretary of State's Geauxbiz portal allows name searches. Entity names must be distinguishable from existing registrations in the Secretary of State's records (Louisiana Secretary of State, Corporations Division).
2. Document preparation and filing — Formation documents (Articles of Organization for LLCs; Articles of Incorporation for corporations; a partnership agreement for general partnerships, which may be oral but is advisable in writing) are filed with the Louisiana Secretary of State. The base LLC formation filing fee is set by statute.
3. Registered agent designation — Louisiana law requires every corporation and LLC to maintain a registered agent with a physical Louisiana address. Failure to maintain a registered agent can result in administrative dissolution under La. R.S. 12:1-1421.
4. Operating or governance documents — LLCs adopt an Operating Agreement (not required to be filed with the state but binding among members). Corporations adopt bylaws and hold an organizational meeting to elect officers and ratify initial actions.
5. Tax registration — Entities with employees or taxable sales must register with the Louisiana Department of Revenue for state income tax, sales tax, and employer withholding accounts (Louisiana Department of Revenue).
6. Professional licensing overlay — Entities conducting licensed professional activity (law, medicine, architecture) must comply with the Louisiana Professional Law Corporation Act or applicable licensing board requirements administered by the relevant professional board.

Ongoing compliance obligations

Corporations must file an annual report and pay franchise tax to the Louisiana Department of Revenue. LLCs organized in Louisiana are not subject to an annual franchise tax as of the Louisiana Business Corporation Act's 2014 restructuring, though they remain subject to income tax pass-through obligations at the federal level. Partnerships file no annual report with the Secretary of State but remain subject to Louisiana income tax rules applicable to partnership income flowing to Louisiana-resident partners.

Common scenarios

Entity conversion: Louisiana law permits conversion of an existing entity from one form to another without dissolution, governed by La. R.S. 12:1-9.01 et seq. A general partnership converting to an LLC files a Statement of Conversion with the Secretary of State.

Member or shareholder disputes: Louisiana courts apply the Operating Agreement or corporate bylaws as the primary governance document. Where those documents are silent, the default rules of La. R.S. 12:1301 et seq. (LLCs) or La. R.S. 12:1-101 et seq. (corporations) fill the gap. Judicial dissolution under La. R.S. 12:1-1430 is available when deadlock or oppressive conduct by controlling shareholders is established.

Foreign entity registration: A business entity formed in another state conducting business in Louisiana must register as a foreign entity with the Louisiana Secretary of State under La. R.S. 12:1-1501 et seq. Conducting business without registration exposes the entity to penalties and bars access to Louisiana courts as a plaintiff until registration is cured.

Single-member LLCs: Louisiana recognizes single-member LLCs. The IRS disregards them as separate entities for federal income tax purposes by default, but Louisiana courts treat them as juridical persons for liability purposes, preserving the liability shield if formalities are maintained.

Decision boundaries

The choice among entity types turns on discrete structural factors:

Professional entities: Attorneys and physicians in Louisiana must use entity forms specifically authorized for licensed professionals. The Louisiana State Bar Association (lsba.org) publishes guidance on permissible law firm structures under the Louisiana Rules of Professional Conduct, Rule 5.4.

Tax-driven choices: Federal tax classification — whether an LLC elects S-corporation treatment via IRS Form 2553 or remains a disregarded entity — does not alter the Louisiana entity form but has significant consequences for Louisiana income tax return filing obligations administered by the Louisiana Department of Revenue.

Nonprofit distinction: Nonprofit corporations formed under La. R.S. 12:201 et seq. operate under a separate statutory framework not addressed on this page. The nonprofit form is outside the scope of business entity comparisons presented here.
