Louisiana at a glance
This guide explains Business License requirements in Louisiana, including eligibility, documents, application steps, testing, fees and renewal.
How Business Licensing Works
<p>Businesses should register for the Louisiana tax accounts that apply and determine local occupational-license and industry-specific permit requirements before operating.</p>
Costs, timing and validity
Louisiana does not have one universal business license. Businesses may need a Louisiana Revenue Account Number, state tax registrations, local occupational licenses and industry-specific permits.
Louisiana Revenue Account registration itself generally does not have a universal fee. Specific licenses, permits and local occupational licenses can have separate fees.
Renewal depends on the tax account or license. Some Louisiana tax registrations remain active while the business operates, while permits and licenses may renew annually.
There is no universal validity period for Louisiana business licenses. The issuing agency or local authority sets the term and renewal requirements.
Documents and information to prepare
Use the official checklist linked on this page as the final authority. The items below describe the information this state commonly expects for this credential.

How to apply
Register through Louisiana Department of Revenue online services or LaTAP.
Complete the appropriate business registration and then obtain local and activity-specific licenses through the responsible agencies.
Licensing & Compliance Checks
<p>General tax registration does not require an examination. Regulated occupations and industries can require exams, education, inspections or other qualifications.</p>
Renewal and ongoing requirements
<p>Keep tax accounts and licenses current, file required returns electronically where required, and update or close registrations when the business changes or stops operating.</p>
Processing time
Processing varies by registration and agency. Louisiana provides electronic registration and filing through its tax systems; additional permits may require separate review.
