How to Register a Foreign LLC in Louisiana (2026)

Fact-checked by the LegalGlass editorial team against primary sources · Published Aug 6, 2026 · Last updated Aug 6, 2026

You register a foreign LLC in Louisiana by filing an Application for Authority to Transact Business with the Secretary of State through geauxBIZ and paying a $150 fee. You must appoint a Louisiana registered agent and provide a recent Certificate of Good Standing from your home state.

What Foreign LLC Registration Means in Louisiana

In business law, "foreign" does not mean international - it means formed in another U.S. state. If your LLC was created in another state and you want to legally do business in Louisiana, you must register it as a foreign LLC with the Louisiana Secretary of State. This is often called foreign qualification, and it is separate from originally forming an LLC.

Registration puts your out-of-state LLC on the Louisiana record, subjects it to Louisiana taxes and reporting, and lets it sue in Louisiana courts and obtain local licenses. Transacting business without qualifying can bar your LLC from bringing lawsuits in Louisiana and expose it to penalties. Review our registered agent and glossary pages for the underlying terms.

When You Must Register in Louisiana

You generally must qualify when your LLC is "transacting business" in Louisiana - typically maintaining a physical location or employees, holding real estate, or having a regular in-state presence. Louisiana's LLC statute, Louisiana Revised Statutes Title 12, lists activities that by themselves do not require registration, such as maintaining a bank account, holding an isolated transaction completed within a set period, or defending a lawsuit.

There is no single bright-line test, so weigh the frequency and nature of your Louisiana activity. Occasional online sales to Louisiana customers usually do not require qualification, but opening an office or hiring in-state employees does. When in doubt, review the statute or consult a professional; the safest course when you have a real presence is to register before you begin operating.

Appoint a Louisiana Registered Agent

A foreign LLC must appoint and maintain a Louisiana registered agent with a physical street address in the state. The agent receives service of process and official notices for the company. You name the agent on the registration application.

You can hire a commercial registered agent or use a qualifying individual resident in Louisiana. Because your management may be out of state, a reliable local agent is important - a missed service of process can lead to a default judgment. If the agent changes later, file the state's change-of-agent form with the Louisiana Secretary of State. See our national registered agent overview for how the role works.

How to File the Louisiana Foreign Registration

You register by filing the Application for Authority to Transact Business with the Louisiana Secretary of State, generally through the geauxBIZ system, and paying the $150 fee. Most states require a Certificate of Good Standing (or Existence) from your home state, usually dated within the last 60 to 90 days, proving your LLC is active there.

The application asks for your LLC's legal name, home state and formation date, principal office, and Louisiana registered agent. If your existing name is unavailable in Louisiana, you register under an assumed or fictitious name and may file a Louisiana DBA. Louisiana filings typically run through the geauxBIZ portal. After approval, you can open bank accounts, obtain Louisiana licenses, and operate legally.

Louisiana Taxes and EIN for a Foreign LLC

Registering does not change your federal tax status: a single-member LLC stays a disregarded entity and a multi-member LLC a partnership unless you elect S-corp or corporate treatment. You use the same federal EIN you already have; you do not get a new one just for qualifying in Louisiana.

For state purposes, a qualified foreign LLC is treated much like a domestic one. Louisiana taxes income sourced to the state and imposes sales tax through the Department of Revenue. Register with the state tax authority for any Louisiana income, withholding, or sales tax that applies to your activity, and confirm details on our business tax page and the Louisiana LLC tax filing guide.

Ongoing Louisiana Reporting and Good Standing

A qualified foreign LLC must file a Louisiana annual report with the Secretary of State each year on its anniversary date, with a $35 fee. Keeping the report and registered agent current preserves your right to do business and to use Louisiana courts. If you let the registration lapse, the state can revoke your authority, and reinstatement means back reports and fees.

Maintain the same corporate formalities you follow at home - separate bank accounts, clean records, and timely filings - so your liability shield holds in Louisiana. If you stop doing business in Louisiana, formally withdraw the registration by filing the state's certificate of withdrawal rather than simply abandoning it, which keeps report and tax obligations running.

Louisiana Foreign LLC Costs and Documents

The table lists the core items for qualifying a foreign LLC in Louisiana. Amounts are effective for 2026; confirm current figures on the Louisiana Secretary of State fee schedule before filing.

Budget also for a Louisiana registered agent if you hire one and for any Louisiana licenses your activity requires.

Verify Current Details and Avoid Common Pitfalls in Louisiana

State fees, tax rates, forms, and deadlines change from year to year, so before you file or pay anything, confirm the current figures directly on the official Louisiana agency websites cited below. The amounts on this page are effective for 2026 and are set by the government, not by any filing service. Public records and most state forms are free or low-cost, and a federal EIN is always free from the IRS - be cautious of third-party websites that charge inflated fees to file routine state paperwork or to obtain a number the government issues at no cost. Reading the primary source yourself is the surest way to avoid outdated or misleading second-hand information, which is exactly why every figure here links to a Louisiana agency, statute, or the IRS.

A second common pitfall is blurring the line between you and your business. If you operate through an LLC or corporation, the liability protection depends on treating the entity as genuinely separate: keep a dedicated business bank account, sign contracts in the company name, keep clean records, and adopt an operating agreement even if Louisiana does not require you to file one. Commingling personal and business money is the fastest way to weaken the shield if the company is ever sued. Owners should also plan for taxes early - set aside money for income and self-employment tax, and review whether an S-corp election fits once profits grow. See our business tax overview for how the pieces connect.

Finally, do not confuse a state business registration with trademark ownership. Clearing a name in the Louisiana business entity search means no other registered entity has that exact name - it does not grant nationwide rights or clear a federal trademark, so search the USPTO database before you invest in branding. Likewise, if you use a name different from your legal entity name, file a Louisiana DBA. When your business changes or winds down, follow the proper Louisiana dissolution steps rather than simply abandoning the entity, which leaves fees and filings running.
