Louisiana Sales Tax Guide

Do You Need to Collect and Remit Sales Tax in Louisiana? 

The answer to this question can be complicated. Whether you need to collect and remit Louisiana sales tax depends on several factors—such as nexus, the taxability of what you sell, and your business activities in the state.

That said, the general rule is straightforward: retailers selling into Louisiana must collect sales tax on most sales of tangible personal property. This includes items such as clothing, furniture, electronics, and similar goods. Louisiana also taxes certain services, such as printing and copying services, auto repairs, software-related services, and cleaning services.

Louisiana’s base state sales tax rate historically sat at 4.45%, but effective January 1, 2025 the state rate increased to 5%. Certain services—such as telecommunications, cable and satellite television, and satellite radio services—are subject to an additional 5% state tax, resulting in a higher effective state rate for those transactions. Additionally, local jurisdictions—called parishes—may impose additional sales taxes on top of the state rate, often bringing the combined rate significantly higher.

However, Louisiana does exempt several common items from state sales tax. Key exemptions include:

• Food for home consumption (most groceries)
• Residential utilities
• Prescription drugs
• Sales for resale when a valid Louisiana resale certificate is provided

Additionally, following Louisiana’s 2024–2025 tax reforms, feminine hygiene products and diapers are now fully exempt statewide.

Understanding which items are taxable versus exempt is often referred to as a taxability matrix, and it’s one of the most important factors businesses must consider when determining whether they need to register for Louisiana sales tax collection.

Do You Have Sales Tax Nexus in Louisiana? 

Before you are required to collect and remit Louisiana sales tax, your business must first have sales tax nexus with the state. Nexus simply means a sufficient connection to a state that allows it to require a business to collect and remit tax.

Louisiana recognizes two primary forms of nexus: physical nexus and economic nexus.

Louisiana also uses slightly different terminology than many states when referring to businesses with different types of nexus:

• Businesses with a physical presence in Louisiana are called Dealers
• Out-of-state businesses that meet economic nexus thresholds are called Remote Sellers

Physical Sales Tax Nexus in Louisiana 

Physical nexus exists when a business has a tangible presence in Louisiana.

Common examples include:

• Operating a storefront or retail location
• Maintaining an office, warehouse, or storage facility
• Storing inventory in a third-party warehouse or fulfillment center
• Having employees, representatives, agents, installers, or salespeople working in the state

Once physical nexus is established, the business is considered a Louisiana dealer.

Dealers with physical nexus must collect and remit both the state sales tax (5%) and any applicable local parish taxes.

Economic Sales Tax Nexus in Louisiana 

Even if your business has no physical presence in Louisiana, you may still be required to collect tax if your sales into the state exceed the economic nexus threshold.

Louisiana’s current economic nexus threshold is:

• $100,000 in gross sales to Louisiana customers during the current or previous calendar year

Up until August 1, 2023 there was also a “200 separate transactions” test, but that has been eliminated. Only the $100,000 sales test now applies.

Once a remote seller exceeds this threshold, they must register and begin collecting Louisiana sales tax on future taxable sales.

Are Marketplace Facilitators Required to Collect and Remit Sales Tax in Louisiana? 

Yes. Louisiana law requires marketplace facilitators to collect and remit sales tax on behalf of sellers when certain thresholds are met. If a marketplace facilitator exceeds $100,000 in retail sales to Louisiana customers, the facilitator must collect and remit sales tax for those transactions.

Two key rules worth noting:

• The 200-transaction threshold was eliminated for marketplace facilitators as well.
• Only retail sales count toward the threshold; wholesale transactions are excluded.

This means that if your products are sold through a qualifying marketplace facilitator, the platform handles the sales tax collection and remittance for those sales for you.

However, if you also make direct sales outside the marketplace, those sales may still trigger nexus obligations for your business.

Common marketplace facilitators include:

• Amazon 
• eBay 
• Shopify Shop App
• Etsy    
• Walmart marketplace  

Filing Louisiana Sales Tax 

Dealers and Remote Sellers have different registration and filing pathways. Below is a simplified overview of the process.

Louisiana’s hybrid system—where dealers often interact with both the state and local parishes—can make compliance more complicated than in most states. SalesTaxSolutions.US helps businesses register, manage filings, and maintain compliance across multiple states—without the headache of tracking every rule change yourself.

Vendor Compensation

Louisiana allows businesses to keep a small portion of the taxes they collect as vendor compensation, provided returns are filed and paid on time. The current compensation rate is 1.05% of the tax collected, capped at a maximum of $750 per month (effective Jan 1, 2025). This discount applies to both dealers and remote sellers who meet the filing and payment requirements.

While the discount isn’t huge, it’s a nice incentive for filing on time.

When Are Sales Tax Returns Due in Louisiana?

Louisiana assigns one of two filing frequencies for sales tax: monthly or quarterly. These are typically assigned based on monthly tax liability. The more tax due, the more often a business will need to file. Regardless of frequency, tax returns are due on or before the 20th of the month following the reporting period.

Examples:

• January monthly return → due February 20
• First-quarter return → due April 20

Important note for dealers filing through Parish E-File:

If you want to submit combined state and local returns, your filing frequencies must align across all participating tax jurisdictions. If they do not, you may need to request a filing frequency change through the Parish E-File system.
