Louisiana does not issue a single “vendor’s license.” To sell goods or services in the state, you register for a state sales tax certificate with the Louisiana Department of Revenue and then add whatever product-specific, professional, and local permits your business actually triggers. Most vendors start at the state’s geauxBIZ portal, which handles business formation and routes registrations to the Secretary of State, the Department of Revenue, and the Louisiana Workforce Commission in one pass.1Louisiana Secretary of State. File Business Documents The portal also generates a customized list of federal, state, and local licenses your specific business may need, though that list is a starting point rather than a final answer.2Louisiana State Legislature. Louisiana Code RS 49:229 – Office of GeauxBiz
Several high-population parishes, including East Baton Rouge, Jefferson, Orleans, and Lafayette, have required online filing through geauxBIZ since January 2018.3Louisiana Secretary of State. Get Forms and Fee Schedule
The Sales Tax Certificate: The Baseline Registration
Any person who sells tangible personal property, digital products, or taxable services at retail in Louisiana qualifies as a “dealer” under state law and must apply for a sales tax certificate from the Louisiana Department of Revenue.4Louisiana Department of Revenue. General Sales and Use Tax This certificate is what authorizes you to collect and remit state sales tax, and it is separate from any business formation filing you complete with the Secretary of State.
The state sales tax rate is 5%, effective January 1, 2025, and set to hold at that rate through at least December 31, 2029.5Louisiana Department of Revenue. What Is the State Sales Tax Rate? Local parishes and municipalities add their own sales taxes on top of that. As of January 2025, Louisiana’s tax base also includes digital products and services at both state and local rates under Act 10 of the 2024 Third Extraordinary Session, so vendors who used to sell only tangible goods may now owe tax on digital offerings.6Louisiana Sales and Use Tax Commission.

Permits Beyond the Sales Tax Certificate
What you sell drives the rest of the licensing list. The categories below are the ones vendors most often need to add.
Food Vendors
If you sell food to the public, you need a retail food permit from the Louisiana Department of Health’s Office of Public Health. The state’s Retail Food Program oversees nearly 34,000 permitted establishments, including restaurants, grocery stores, bakeries, mobile food vendors, and seasonal or temporary operations.7Louisiana Department of Health. Retail Food Program The department publishes guidance for new food businesses covering permitting, inspection, and fees.8Louisiana Department of Health. Retail Food – For New Businesses
Tobacco and Alcohol
Vendors selling tobacco products, vapor products, or alcoholic beverages must obtain a permit for each place of business and each vending machine before selling, and the state permit must be in hand before operations begin. These permits are handled by Louisiana’s Alcohol and Tobacco Control office.9Justia. Louisiana Revised Statutes Title 26 RS 26:906 – General Requirements Alcohol sellers also need to satisfy local zoning and location restrictions before the parish or municipality will issue a certificate of zoning compliance.
Regulated Professions
Service providers in regulated professions need a license from the appropriate state board. Architects, for instance, must obtain a certificate of authority from the Louisiana State Board of Architectural Examiners, and the architectural work itself must be performed by or under the supervision of a Louisiana licensee.10Cornell Law School. La. Admin. Code tit. 46 I-1701 – Professional Architectural Corporations Engineers, contractors, and other regulated professionals face comparable board-level requirements, and some boards offer reciprocity when an out-of-state licensee’s home-state standards meet or exceed Louisiana’s.11Justia. Louisiana Revised Statutes Title 37 RS 37:3161 – Qualification by Reciprocity
Local Occupational License Taxes
Most Louisiana parishes and municipalities require an occupational license tax for anyone pursuing a trade, profession, or business within their jurisdiction. The tax is typically calculated on your business classification and gross receipts, with minimums that start around $50 per business location. A city inside a parish may impose its own separate license on top of the parish tax, so a single vendor can owe both. The parish sheriff’s office or municipal licensing department is the right place to confirm what applies to your address.
Zoning and Bonds
Before a license or permit issues, Louisiana generally requires proof that your business location complies with local zoning laws. In many parishes the occupational licensing process starts with a Certificate of Zoning Compliance from the local planning and zoning department, confirming that commercial activity is permitted at your address.12St. Charles Parish, LA. Economic Development and Tourism Frequently Asked Questions
Certain license types also require a surety bond. Tobacco product distributors must file a bond with the Secretary of the Department of Revenue upon approval of the application; the secretary can waive it for licensees who maintain Louisiana assets worth at least one and a quarter times the bond amount otherwise required.13Louisiana State Legislature. Louisiana Code RS 47:818.40 – Bond Requirements; Amounts Motor vehicle dealers face a separate bonding requirement, and letting the bond lapse triggers immediate license suspension.14Louisiana State Legislature. Louisiana Revised Statutes 32:1254 – Application for License; Requirements for Licensure
Out-of-State and Remote Sellers
Vendors based outside Louisiana carry the same licensing obligations as in-state businesses, with additional registration tied to how they reach Louisiana customers.
If you have a physical presence in Louisiana such as an office, warehouse, or in-state employees, you register as a “dealer” for a sales tax certificate with the Department of Revenue, and you register with each parish where you collect tax, since local sales tax administration is handled separately from the state.15Louisiana Sales and Use Tax Commission. Frequently Asked Questions – Louisiana Sales and Use Tax
Without physical presence, you register with the Louisiana Sales and Use Tax Commission for Remote Sellers if, in the previous or current calendar year, you meet either of these thresholds:
- Gross revenue over $100,000 from sales of tangible personal property, digital products, or services delivered into Louisiana, or
- 200 or more separate transactions for delivery into Louisiana.
The Commission is a single registration and remittance point, so remote sellers do not register with every parish individually.15Louisiana Sales and Use Tax Commission. Frequently Asked Questions – Louisiana Sales and Use Tax The Louisiana Uniform Local Sales Tax Board oversees the uniform electronic local return and remittance system that supports it.16Louisiana State Legislature. Louisiana Code RS 47:337.102 – Louisiana Uniform Local Sales Tax Board; Creation; Membership; Powers and Duties
One narrow federal protection: an out-of-state vendor whose only Louisiana activity is soliciting orders for tangible personal property may be shielded from Louisiana income tax under Public Law 86-272, provided orders are sent outside the state for approval and filled by shipment from outside Louisiana. The protection does not reach Louisiana-incorporated entities, Louisiana residents, or vendors selling services or digital products.
Act 11 of the 2024 Third Extraordinary Session repealed vendor compensation for remote sellers, so remote sellers no longer receive a discount for timely filing and remittance. That same act changed return reporting: all parishes must now capture separate sales amounts for prescription drugs and manufacturing machinery and equipment, and vendors using the remote seller return must report these categories on separate lines.6Louisiana Sales and Use Tax Commission. Announcements – Louisiana Sales and Use Tax Commission
Renewals and Staying Current
A license is not a one-time transaction. Professional licenses are typically renewed annually. The Louisiana Professional Engineering and Land Surveying Board, for instance, accepts renewal applications between October 1 and December 31 each year, and a lapsed license can be reinstated within one year by paying both the renewal fee and a reinstatement fee.17Cornell Law School. La. Admin. Code tit. 46 XCI-301 – Licensing, Renewal and Reinstatement Requirements Other license types run on biennial or different cycles, so confirm the schedule with each issuing authority.
If your business handles customer personal information, Louisiana’s data breach notification law requires notice to affected individuals and to the attorney general after a security breach. Failing to notify the attorney general on time can produce fines of up to $5,000 per day, and the violation also counts as an unfair trade practice.18Cornell Law School. La. Admin. Code tit. 16 III-701 – Reporting Requirements19Louisiana State Legislature. Louisiana Code RS 51:3074 – Protection of Personal Information; Notification Requirements
Penalties for Operating Without the Right License
Fines vary by license. Unlicensed contractors face up to $500 per day of violation and up to three months in jail; if the unlicensed work causes harm or damage exceeding $300, the range climbs to fines of $500 to $5,000 and imprisonment of six months to five years.20Justia. Louisiana Revised Statutes Title 37 RS 37:2160 – Engaging in Business of Contracting Without Authority Prohibited; Penalty Licensed contractors who violate board rules can be fined and have their license suspended or revoked after a hearing.21Cornell Law School. La. Admin. Code tit. 46 XXIX-707 – License Revocation and Suspension
Agencies can suspend or revoke a license for misstatements on the application, failure to comply with licensing rules, defrauding customers, or fraudulent misrepresentation. Revocation ordinarily requires at least 30 days’ written notice and a hearing, though in emergencies involving public health or safety, a summary suspension can take effect immediately while revocation proceeds.22Cornell Law School. La. Admin. Code tit. 46 V-7307 – Suspension, or Revocation of License
The costliest penalty for many unlicensed vendors is not a fine at all. Under Louisiana law, a contract made in violation of a licensing statute is treated as an absolute nullity, meaning courts treat it as if it never existed. An unlicensed contractor cannot sue to enforce the contract or collect the agreed price. Courts have generally limited recovery to the actual cost of labor and materials, with no allowance for overhead or profit, and an unlicensed contractor cannot assert a valid lien against the property. The lost enforceability tends to dwarf whatever fine the board would have imposed.
