Understanding Louisiana’s Sales Tax System
Louisiana combines a 4.45% state sales tax with additional parish sales taxes, so the total rate depends on where the customer receives the product.
Remote sellers generally register and file through the Louisiana Sales and Use Tax Commission for Remote Sellers, while businesses with a physical presence typically register with the Louisiana Department of Revenue and any applicable parish tax authorities.
What Is Taxable in Louisiana?
Most tangible personal property sold in Louisiana is taxable, including:
- Clothing

How to Register for a Louisiana Sales Tax Permit
Registration depends on your business:
- Remote sellers register through the Louisiana Sales and Use Tax Commission.
- Businesses with a physical presence register with the Louisiana Department of Revenue and any applicable parish tax authorities.
Provide your business information and EIN to complete the application. Registration is typically processed within a few business days.
Filing Frequency and Due Dates
| Filing Frequency | Requirement | Due Date |
| Monthly | Generally over $500 collected per month | 20th of the following month |
| Quarterly | Assigned by the Department of Revenue | Assigned |
| Annual | Lower-volume businesses | Assigned |
Businesses must file required returns even if no tax is due. State returns are due on the 20th of the month following the reporting period. Parish filing deadlines vary: some align with the state, others don’t. If you’re filing through the Sales and Use Tax Commission as a remote seller, your deadlines follow the commission’s schedule, which simplifies things considerably.
Set calendar reminders for every deadline. Late filings trigger automatic penalties, and Louisiana’s penalty structure includes both a percentage-based penalty and interest on unpaid tax.
Marketplace Facilitator Rules
Marketplace facilitators such as Amazon, Etsy, Walmart Marketplace, and eBay generally collect and remit Louisiana sales tax on marketplace sales. If you also sell through your own website or directly to customers, you’re responsible for collecting tax on those sales if you have nexus.
