Forming an LLC in Louisiana costs $100 to file Articles of Organization with the Louisiana Secretary of State, with online approval through geauxBIZ in 1–3 business days. Expedited service is available — 24-hour for $30 extra and 2–4 hour for $50 extra. The annual report is $35, due in the LLC's anniversary month. Louisiana moved to a flat 3% individual income tax in 2025, one of the largest tax cuts in state history. The catch is sales tax: combined state and local rates can push above 11.5%, the highest in the U.S. Louisiana is also unique because it operates under a civil law system (the only U.S. state to do so), inherited from French colonial law — meaning some contract and property concepts work differently than in other states. Strong industries include oil and gas, petrochemicals (the Mississippi River corridor), maritime/ports (New Orleans), and seafood. For those operating in Louisiana, a local attorney is unusually valuable.
How much does a Louisiana LLC cost?
Starting a Louisiana LLC runs about $249 in Year 1 — that's the $100 state filing fee to the Secretary of State plus roughly $149 for a registered agent service. Processing takes 3–5 business days once your Articles of Organization are submitted online. Louisiana does not impose a franchise tax or a high minimum annual fee the way California ($800) or Tennessee ($300) do, which makes it one of the more affordable Gulf Coast options for new business owners. Your ongoing obligation is a $35 annual report, keeping five-year costs around $424 without a registered agent or closer to $1,169 if you keep the agent service each year. The main cost trap to watch: missing the annual report deadline triggers late fees and can lead to administrative dissolution, so calendar that due date the moment your LLC goes active.

Louisiana is the only U.S. state whose legal system descends from the Napoleonic Code rather than English common law. That distinction is not merely academic — it changes how courts interpret LLC operating agreements, member fiduciary duties, and dissolution disputes. Clauses that function predictably in a Delaware or Texas LLC can produce unexpected outcomes in a Louisiana courtroom because civilian judges rely on codified statutes and Civil Code principles rather than centuries of common-law precedent. Beyond the legal system, Louisiana imposes a $110 minimum corporate franchise tax on LLCs that elect corporate taxation, a trap that catches owners who switch tax classification for federal purposes without realizing the state consequences. Louisiana also requires a one-time Initial Report filed within 30 days of the Secretary of State accepting your Articles of Organization — a step most states do not require at all. Miss it and the LLC is technically non-compliant from the start. The oil, gas, and maritime industries dominate the state's economy, and LLCs in those sectors often need additional state-level licensing through the Louisiana Department of Natural Resources, adding cost and timeline the $100 filing fee does not reflect.
Year 1: $100 (Articles of Organization filing) + $149 (registered agent) + $0 (annual report not yet due in formation year for most filers) + $50 (estimated Initial Report and compliance buffer) = $299 total. By Year 5: add four annual reports at $35 each ($140) and four additional registered agent years ($596), bringing the five-year total to approximately $1,035 — assuming pass-through taxation and no corporate franchise tax exposure.
Skipping the Initial Report due within 30 days of formation. Unlike most states that only require an annual report, Louisiana mandates this one-time filing shortly after approval. Owners who treat formation as complete once their Articles are accepted routinely miss this deadline, leaving the LLC out of good standing before it has even opened a bank account or signed its first contract.
Louisiana LLC: frequently asked questions
How much does it cost to start an LLC in Louisiana?
Louisiana Secretary of State charges $100 to file Articles of Organization through geauxBIZ. The annual report is $35, due in the LLC's anniversary month. Realistic year-one cost: $100. Ongoing yearly cost: $35.
How long does it take to form an LLC in Louisiana?
Online filings through geauxBIZ approve in 1–3 business days. Expedited 24-hour processing is $30 extra; 2–4 hour processing is $50 extra. Mail filings take 7–10 business days.
Does Louisiana have an LLC franchise tax?
No franchise tax for LLCs taxed as pass-through (the default). LLCs that elect C-corporation taxation are subject to Louisiana's corporate franchise tax, which is being phased out (set to be eliminated entirely by 2026).
What is Louisiana's LLC tax rate?
Louisiana moved to a flat 3% individual income tax in 2025 — one of the largest cuts in state history. Sales tax is 5% statewide plus parish and municipal rates that can push combined rates above 11.5% (the highest in the U.S.). LLCs taxed as pass-through don't owe state-level entity tax — owners pay 3% on their share of profits.
When is the Louisiana LLC annual report due?
In the LLC's anniversary month each year. The fee is $35. File through geauxBIZ. Late filings incur a $25 penalty and can lead to administrative dissolution.
Can a non-resident form an LLC in Louisiana?
Yes. Louisiana has no residency requirement for LLC members or managers. You only need a Louisiana-based registered agent. Out-of-state owners commonly use a commercial registered agent service.
Is Louisiana a good state to form an LLC?
For Louisiana residents and businesses tied to oil/gas, petrochemicals, ports/maritime, hospitality, or seafood industries: yes. The recent tax cuts (3% flat income tax) help. The civil law system is genuinely different — multi-state founders should work with a Louisiana-licensed attorney for any complex contracts. The high combined sales tax is a real cost for retail.
What's different about Louisiana civil law?
Louisiana is the only U.S. state with a civil law system (inherited from French Napoleonic Code), while all 49 other states use common law. The differences mostly affect contracts, property rights, inheritance, and some commercial concepts. For LLC formation, the practical impact is small — but for substantial business contracts, real estate, or estate planning involving Louisiana, work with a Louisiana attorney.
