Professional Corporation Basics
Louisiana professional corporations serve licensed professionals who need corporate structure while maintaining compliance with professional licensing requirements. These entities are available to accountants, attorneys, physicians, dentists, chiropractors, nurses, optometrists, and other regulated professionals who must follow specific ownership and naming rules.
Professional corporations in Louisiana operate under the same general corporate laws as standard corporations, with additional restrictions tied to professional licensing. The key differences involve naming requirements, ownership eligibility, and ongoing compliance with professional boards. Unlike general corporations that can have any qualified shareholders, professional corporations typically restrict ownership to licensed professionals within the same field.
The formation process follows standard corporate procedures through the Louisiana Secretary of State, but professional corporations must also maintain good standing with their respective licensing boards. This dual compliance requirement makes entity verification more complex for lenders and legal teams conducting due diligence.
Louisiana Secretary of State Search Portal
The Louisiana Secretary of State maintains the Commercial Database at State business search portal, providing real-time access to business entity information. This portal serves as the official record for all Louisiana corporations, including professional corporations, and offers comprehensive search capabilities for verification workflows.
The database returns up to 250 results per search and includes business names, entity types, locations, status indicators, and detailed filing histories. Users can search by entity name, registered agent, or charter number. The system excludes corporate designators during searches, so entering "Smith Medical" will return results for "Smith Medical Corporation" and "Smith Medical, LLC."
Search results display basic information with a "Details" button that reveals complete entity profiles. The detail view shows charter numbers, formation dates, registered agents, officer information, business addresses, and chronological filing records. This information updates in real-time as the Secretary of State processes new filings.
For preliminary name availability checks, the portal provides immediate feedback, though final name approval occurs during the formal filing process. The database also includes revoked entities, which remain unavailable for new formations for three years following revocation.
Name Availability Verification Steps
Professional corporations must verify name availability before filing Articles of Incorporation. Louisiana requires names to be distinguishable from existing corporate, LLC, and trade names on file with the Secretary of State.
Start your search by entering the proposed name without corporate designators in the Commercial Database. The system checks for exact matches and similar variations, including phonetic similarities and common spelling alternatives. For example, searching "Cajun" will also flag "Kajun" as potentially conflicting.
Conduct multiple search variations to identify potential conflicts. Search partial names, alternate spellings, and abbreviated versions. Remove special characters like commas, periods, and apostrophes, as these do not affect name availability determinations. Case sensitivity does not apply to Louisiana business name searches.
If the preliminary search shows availability, contact the Secretary of State at 225.925.4704 for verbal confirmation before proceeding with formation documents. For added protection, consider filing a name reservation for $25, which holds the name for 60 days with two possible 30-day extensions.
Remember that preliminary searches are not definitive. The Secretary of State conducts a more thorough examination during the formal filing review, which may identify conflicts not apparent in initial searches.
Entity Status and Filing History Review
Louisiana professional corporations display various status indicators that reflect their current standing with the Secretary of State. Active corporations show "Active" or "Good Standing" status, while inactive entities may display "Revoked," "Dissolved," or "Merged" designations.
The entity detail view provides complete filing histories, including formation dates, annual report submissions, registered agent changes, and amendment filings. This chronological record helps verify compliance patterns and identify any lapses in required filings.
Pay attention to registered agent information, as Louisiana requires professional corporations to maintain a registered agent with a physical address within the state. Post office boxes are not acceptable for registered agent addresses. The registered agent must be available during normal business hours to accept legal and tax documents.
Review officer and director information for accuracy and currency. Louisiana requires directors to have physical addresses rather than post office boxes. For professional corporations, verify that listed officers meet professional licensing requirements for their respective fields.
Check for any outstanding compliance issues by reviewing the most recent annual report filing date. Louisiana corporations must file annual reports to maintain good standing, and lapses can result in administrative dissolution or revocation. Understanding these common entity status labels helps interpret search results accurately.
Professional-Specific Naming Requirements
Louisiana imposes specific naming rules for certain professional corporations that differ from general corporate naming requirements. Law, dental, accounting, chiropractic, nursing, and optometry professional corporations must include the full or last name of one or more voting shareholders, former voting shareholders, or members of a predecessor firm in their corporate name.
For example, a law firm professional corporation might be named "Johnson, Smith & Associates, Professional Corporation" or "Johnson Law Corporation." This requirement ensures clear identification of the professionals responsible for the entity's operations and maintains accountability within regulated professions.
Other regulated professions have more flexibility in naming. They may either comply with the name inclusion requirement or use any name approved by the Secretary of State, provided it meets general distinguishability standards and includes appropriate corporate designators.
All professional corporations must include a corporate designator such as "Corporation," "Incorporated," "Company," or their abbreviations. Professional corporations may also use "Professional Corporation" or "P.C." as designators, which clearly identifies their professional status.
When conducting name searches for professional corporations, consider these naming requirements early in the verification process. Names that comply with general corporate rules may still be rejected if they fail to meet profession-specific requirements.
Certificate of Authority for Foreign Entities
Foreign professional corporations operating in Louisiana must obtain a Certificate of Authority from the Louisiana Secretary of State. This requirement applies to professional corporations formed in other states that conduct business activities within Louisiana.
The Certificate of Authority application requires a certificate of existence or certificate of good standing from the professional corporation's home state, dated within 90 days of submission. This document must be submitted to the Louisiana Secretary of State's Commercial Division along with the completed application and $125 filing fee.
The application process includes designating a registered agent with a physical address in Louisiana and providing detailed information about the corporation's business activities, officers, and directors. Foreign professional corporations must also comply with Louisiana's professional licensing requirements for their specific field.
Verify Certificate of Authority status through the Commercial Database by searching for the entity name and reviewing the filing history. Active Certificates of Authority appear in the entity's record along with the original authorization date and any subsequent amendments.
Foreign professional corporations must maintain their Certificate of Authority through ongoing compliance, including annual report filings and registered agent maintenance. Failure to maintain the certificate can result in revocation and loss of authority to conduct business in Louisiana.
Ongoing Compliance Verification
Professional corporations must maintain compliance with both corporate law requirements and professional licensing standards. This dual compliance creates additional verification steps for lenders and legal teams conducting entity due diligence.
Corporate compliance includes annual report filings, registered agent maintenance, and proper corporate governance. Louisiana requires annual reports with current officer, director, and registered agent information. Late filings can result in administrative penalties and potential revocation of corporate status.
Professional licensing compliance varies by profession but typically includes maintaining individual professional licenses for all shareholders and officers, meeting continuing education requirements, and adhering to professional conduct standards. Some professions require separate entity licensing or registration with professional boards.
Monitor compliance status by regularly checking the Secretary of State database for current entity status and recent filings. Cross-reference with relevant professional licensing boards to verify that individual professionals maintain current licenses and that any required entity-level professional registrations remain active.
For comprehensive entity verification, document both corporate status and professional licensing compliance. This dual verification approach ensures complete due diligence for professional corporation transactions and reduces compliance risks for lenders and legal teams working with licensed professionals.
