Key Takeaways
- Louisiana recognizes the PLLC as a distinct entity type for licensed professionals (La. R.S. 12:1301 et seq. (Title 12, Chapter 22, Louisiana Limited Liability Company Law), cross-referenced against Title 37 professional-board rules)
- Louisiana requires licensing board approval before the filing agency will accept your PLLC filing
- Filing fee: $75 (plus a $5 online service charge)
- Louisiana's woven-in, board-by-board approach means there's no single statutory answer on combining professions — whether a multi-discipline entity works depends on whether every relevant board's practice-act rules permit the combination, so confirm directly with each board rather than assuming a general allied-professions right exists.

If you're a licensed professional in Louisiana — an engineer, land surveyor, attorney, dentist, or similar occupation — Louisiana law lets you form a PLLC, but the sequencing runs backwards compared to most states: you form the entity first, then apply for firm licensure with your board within 30 days.
This guide covers exactly how to form a Louisiana PLLC in 2026 — the post-formation board licensure model confirmed for engineers and surveyors, the $75 filing cost, and what liability protection a PLLC actually provides for negligent professional acts.
What Is a Louisiana 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.
Yes. Louisiana recognizes the PLLC as a distinct entity type for licensed professionals (La. R.S. 12:1301 et seq. (Title 12, Chapter 22, Louisiana Limited Liability Company Law), cross-referenced against Title 37 professional-board rules).
Who Needs a PLLC in Louisiana?
Louisiana weaves its professional-practice rules into the general LLC chapter and cross-references Title 37 board rules rather than maintaining one master PLLC list. Attorneys and dentists are confirmed by direct statutory cross-reference; engineers and land surveyors are confirmed through the Louisiana Professional Engineering and Land Surveying Board (LAPELS). CPAs, architects, physicians, and other licensed professions commonly use the PLLC route as well, each governed by their own board's practice-act rules.
Because Louisiana doesn't centralize its professional-LLC rules in one place, some licensed professions may be able to use a plain LLC where their governing board doesn't specifically require the professional designation — confirm with your board rather than assuming either direction.
Do I Need Licensing Board Approval First?
Louisiana uses a distinctively post-formation model rather than a pre-filing gate. Your LLC forms first with the Secretary of State — but for confirmed professions like engineering and surveying, the firm must then submit an application for firm licensure to the relevant board (LAPELS, for example) within 30 days of the Secretary of State issuing your Certificate. The board then has up to 60 days to act on that application.
This is the opposite sequencing from states like Illinois, Kansas, or Massachusetts, where board approval happens before or at the same time as state filing. In Louisiana, you form the entity first, then you're on a 30-day clock to apply for firm licensure with your board — missing that window can leave your new entity practicing without the firm-level licensure it needs, even though the entity itself is validly formed.
How to Form a Louisiana PLLC
- Filing agency: Louisiana Secretary of State, Commercial Division
- Form: Articles of Organization (filed together with an Initial Report — Louisiana won't accept Articles without one)
- Filing fee: $75 (plus a $5 online service charge)
- Processing time: Typically a few business days for standard online processing
- Expedited option: 24-hour expedited processing available for an added fee through geauxBIZ
- Name requirement: Must include "limited liability company" or "professional limited liability company," or the abbreviation "L.L.C.," "P.L.L.C.," or "L.C." — Louisiana permits the plain "L.L.C./L.C." designator even for an entity registered as professional, so the professional designation isn't always visible in the name itself.
Who Can Own a Louisiana PLLC?
Members generally must be licensed in the profession practiced by the company, consistent with each governing board's own practice-act rules; naming must also satisfy any profession-specific board requirement (Louisiana's engineering and surveying board, for instance, must approve name use of "engineer" or "surveyor" before the Secretary of State will register it).
Louisiana's woven-in, board-by-board approach means there's no single statutory answer on combining professions — whether a multi-discipline entity works depends on whether every relevant board's practice-act rules permit the combination, so confirm directly with each board rather than assuming a general allied-professions right exists.
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.
A Louisiana PLLC shields members from each other's malpractice and from ordinary business debts, but never from a member's own negligent professional acts — that liability follows the individual professional regardless of the entity wrapper.
Louisiana doesn't impose a single, blanket malpractice-insurance mandate tied to PLLC formation itself across all professions. Because firm licensure for professions like engineering and surveying happens after formation through the governing board, any insurance or financial-responsibility condition is more likely to surface during that post-formation board review than at the Secretary of State filing stage — confirm directly with your board.
How Is a Louisiana 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.
Louisiana has a flat personal income tax (3% as of the 2025 tax year, following recent tax reform), so a Louisiana PLLC's pass-through profit is taxed at that rate at the state level, on top of federal income and self-employment tax.
Louisiana LLCs, including PLLCs, file an annual report with the Secretary of State ($30-$35 depending on filing method) to stay in good standing, separate from any firm-licensure renewal your professional board requires.
How to Set Up Your Louisiana PLLC Step by Step
If You Do It Yourself
Step 1 — Confirm you need a PLLC (not a plain LLC) for your profession.
Louisiana weaves its professional-practice rules into the general LLC chapter and cross-references Title 37 board rules rather than maintaining one master PLLC list. Attorneys and dentists are confirmed by direct statutory cross-reference; engineers and land surveyors are confirmed through the Louisiana Professional Engineering and Land Surveying Board (LAPELS). CPAs, architects, physicians, and other licensed professions commonly use the PLLC route as well, each governed by their own board's practice-act rules.
Step 2 — Get licensing board sign-off if required.
Louisiana uses a distinctively post-formation model rather than a pre-filing gate. Your LLC forms first with the Secretary of State — but for confirmed professions like engineering and surveying, the firm must then submit an application for firm licensure to the relevant board (LAPELS, for example) within 30 days of the Secretary of State issuing your Certificate. The board then has up to 60 days to act on that application. This is the opposite sequencing from states like Illinois, Kansas, or Massachusetts, where board approval happens before or at the same time as state filing. In Louisiana, you form the entity first, then you're on a 30-day clock to apply for firm licensure with your board — missing that window can leave your new entity practicing without the firm-level licensure it needs, even though the entity itself is validly formed.
Step 3 — File your formation documents.
File the Articles of Organization (filed together with an Initial Report — Louisiana won't accept Articles without one) with Louisiana Secretary of State, Commercial Division, $75 (plus a $5 online service charge).
Step 4 — Appoint a registered agent.
Louisiana calls this role a "Registered Agent" — required at formation.
Step 5 — Confirm ownership eligibility for every member.
Members generally must be licensed in the profession practiced by the company, consistent with each governing board's own practice-act rules; naming must also satisfy any profession-specific board requirement (Louisiana's engineering and surveying board, for instance, must approve name use of "engineer" or "surveyor" before the Secretary of State will register it).
Step 6 — Address malpractice insurance requirements.
Louisiana doesn't impose a single, blanket malpractice-insurance mandate tied to PLLC formation itself across all professions. Because firm licensure for professions like engineering and surveying happens after formation through the governing board, any insurance or financial-responsibility condition is more likely to surface during that post-formation board review than at the Secretary of State filing stage — confirm directly with your board.
Step 7 — Handle ongoing state compliance.
Louisiana LLCs, including PLLCs, file an annual report with the Secretary of State ($30-$35 depending on filing method) to stay in good standing, separate from any firm-licensure renewal your professional board requires. Louisiana has a flat personal income tax (3% as of the 2025 tax year, following recent tax reform), so a Louisiana PLLC's pass-through profit is taxed at that rate at the state level, on top of federal income and self-employment tax.
Step 8 — Watch for Louisiana-specific PLLC traps.
The single most important thing to know about Louisiana is that board approval comes AFTER state formation, not before. Confirmed for engineers and land surveyors through LAPELS: you have 30 days from your Secretary of State Certificate to apply for firm licensure with your board, which then has up to 60 days to act. Treat state formation as step one of two, not the finish line.

When Should You Talk to an Attorney About Your Louisiana PLLC?
Talk to an attorney before forming your Louisiana PLLC if you're unsure which board governs your specific profession's firm-licensure process, if you need help tracking the 30-day post-formation application deadline, or if you're combining multiple licensed professions and need to confirm each board's practice-act rules permit it.
Is Louisiana a State Where PLLC Formation Is More Complex?
Louisiana's PLLC process runs backwards compared to most of the states in this comparison. Instead of getting board approval before or during Secretary of State filing, you form the LLC first and then have a 30-day window (for professions like engineering and surveying, confirmed through LAPELS) to apply for firm licensure with your governing board. If you're used to another state's pre-filing approval model, it's easy to assume Louisiana works the same way and miss that post-formation deadline.
What You Actually Get With LLC Attorney's Louisiana PLLC Formation
The part of Louisiana PLLC formation that trips people up isn't the Secretary of State filing — it's the 30-day clock that starts running the moment your Certificate is issued, during which you must apply for firm licensure with your governing board. LLC Attorney tracks that deadline so it doesn't slip.
