Foreign sellers may need to collect Louisiana sales and use tax even without a Louisiana office, warehouse, employee, or other physical presence. A remote seller generally becomes responsible when, during the previous or current calendar year, its gross revenue from sales of tangible personal property, products transferred electronically, or services delivered into Louisiana exceeds $100,000 or it makes 200 or more separate transactions for delivery into the state. Sellers that meet either test must register with the Louisiana Sales and Use Tax Commission for Remote Sellers, collect the applicable state and local tax, file returns, and remit the tax.
Louisiana is unusual because it is a home-rule state: parishes and other local jurisdictions administer their own local sales taxes. The Louisiana Remote Sellers Commission provides a separate registration and filing route for qualifying remote sellers, allowing one return for state and local taxes on remote sales. The Louisiana Department of Revenue administers the state system, but the correct tax still depends on the product, exemption status, delivery destination, and local rate in effect for that transaction.
What sales tax rate applies in Louisiana?
There is no single Louisiana rate that answers every foreign seller’s question. A taxable Louisiana delivery can include the state sales tax plus applicable parish, municipal, and other local sales or use taxes. The Louisiana Department of Revenue publishes current state and local rate information, while the Remote Sellers Commission requires qualifying remote sellers to calculate tax using the actual applicable tax bases and rates.
A foreign seller should therefore avoid applying one flat Louisiana percentage to every order. The rate can vary by the customer’s delivery address and by whether the item or service is taxable. Before charging tax, confirm the current combined rate and taxability for the destination through the Louisiana Department of Revenue or have a compliance professional review the seller’s transaction data.
When do foreign sellers create Louisiana nexus?
For a seller with no physical presence in Louisiana, economic nexus is generally established when gross revenue from taxable tangible personal property, electronically transferred products, or services delivered into Louisiana exceeds $100,000 during the previous or current calendar year, or when the seller makes 200 or more separate transactions for delivery into Louisiana. Either threshold is sufficient. The rule concerns sales delivered into Louisiana, not merely the seller’s location or currency.
Physical presence can create a separate registration and collection obligation even when the economic thresholds are not met. Inventory, employees, agents, offices, or other in-state activities should be reviewed separately. The exact position depends on the seller’s facts and the current law; confirm the analysis with the Louisiana Department of Revenue or ask Sales Tax Compliance USA to check it for you.
How do foreign sellers register for Louisiana sales tax?
A foreign seller that meets the remote-seller definition registers through the Louisiana Sales and Use Tax Commission for Remote Sellers portal. The Commission is a separate commission specifically for remote sellers because Louisiana’s parishes otherwise administer their own local sales taxes. Registration is intended to support a single return covering state and local tax on qualifying remote sales rather than requiring the seller to register separately in every parish where it has customers.
Registration should be completed before the seller’s collection and filing obligations begin, using the business, responsible-person, contact, and sales information requested by the Commission. Keep the registration details, filing authorization, customer-location records, exemption documentation, and marketplace information consistent. Portal procedures and requested information can change, so check the current Louisiana Department of Revenue registration instructions before submitting an application.
How do parish and local Louisiana taxes work?
Louisiana is a home-rule state. Parishes and other local jurisdictions administer their own local sales taxes, which is why a foreign seller cannot reliably determine tax by looking only at the state rate. A qualifying remote seller reports state and local tax through the Louisiana Remote Sellers Commission, but the tax calculation must still reflect the actual local jurisdiction and applicable local tax base.
Louisiana determines the local tax for a remote sale by the delivery destination and the sourcing rules applicable to that sale. Capture the complete Louisiana delivery address, including parish and municipality where relevant, and retain evidence supporting the address used. If an order is shipped to a warehouse, pickup point, or other nonstandard destination, confirm the correct sourcing treatment rather than assuming the customer’s billing address controls.
What products and services are taxable?
Louisiana’s remote-seller rules cover taxable tangible personal property, products transferred electronically, and taxable services delivered into Louisiana. Taxability is product-specific: a physical good, digital product, subscription, installation charge, warranty, delivery charge, or service may receive different treatment. The fact that a seller is located outside the United States does not by itself make the sale exempt.
Review the Louisiana tax treatment of each product category and the components of the invoice. Do not assume that an item is taxable merely because it is sold online, or exempt merely because it is digital or described as a service. When the classification is uncertain, the prudent course is to confirm it with the Louisiana Department of Revenue or have Sales Tax Compliance USA review the catalog and terms before collection begins.
How do marketplace facilitator rules affect foreign sellers?
A marketplace facilitator generally must collect and remit Louisiana state and local sales and use tax on taxable remote sales that it makes or facilitates for marketplace sellers when the facilitator exceeds the applicable remote-sales threshold. Louisiana law defines a marketplace facilitator broadly around operating a marketplace, offering sellers’ goods or services through it, and collecting payment and transmitting funds to the seller.
Marketplace collection does not automatically eliminate every obligation of the foreign seller. Keep records separating marketplace sales from direct sales, identify the tax collected by each marketplace, and determine whether direct sales independently meet Louisiana’s economic-nexus thresholds. Marketplace agreements may allocate responsibilities, but the seller should not rely on a platform’s tax statement without checking the covered transactions, destinations, exemptions, and filing requirements.
When must foreign sellers file Louisiana returns?
The Louisiana Department of Revenue’s remote-seller guidance states that Remote Sellers Tax Returns and payments for state and local tax on remote sales are due on or before the 20th day of the month following the close of the calendar-month reporting period. For example, a return for a completed monthly period is due by the 20th of the following month, subject to the current filing instructions and any applicable adjustment to the due date when the date falls on a nonbusiness day.
The Commission determines the seller’s assigned filing frequency and may require a different reporting schedule based on the registration and account information. Do not infer the frequency from another state or from the seller’s home country. Check the current Louisiana account notice and Department of Revenue instructions for the assigned period, filing method, zero-return requirement, extensions, and payment timing.
How do foreign sellers file, remit, and calculate Louisiana tax?
Qualifying remote sellers file through the Louisiana Remote Sellers Commission using the Commission’s single-return process for state and local taxes. The seller reports taxable sales, exempt sales, deductions, tax collected, and the local destination information needed to allocate the liability. Payment must be remitted by the applicable due date; filing a return without paying the balance does not satisfy the payment obligation.
The calculation begins with the sale’s Louisiana taxability and taxable measure, then applies the state and local rates and bases for the properly sourced delivery location. Build records that connect each invoice to the ship-to address, product classification, tax rate, exemption certificate or other support, marketplace status, and amount remitted. Sales Tax Compliance USA is a people-led service that can help maintain this workflow, prepare filings, and review exceptions, but the exact treatment should be confirmed against current Louisiana requirements.
Which Louisiana sales tax exemptions apply to foreign sellers?
Louisiana exemptions depend on the purchaser, product, use, and transaction facts. A foreign seller should not assume that an export sale, resale claim, nonprofit customer, government customer, manufacturing use, or other claimed exemption is valid without the documentation Louisiana requires. Exemption treatment can also differ between state and local taxes.
Collect and retain the appropriate exemption certificate or other evidence before treating a transaction as exempt, and validate certificates for completeness and scope. If the customer claims an exemption but cannot provide adequate support, the seller should obtain guidance before removing tax. The Louisiana Department of Revenue can confirm the current exemption requirements for a particular transaction type.
Penalties and practical compliance steps
Failure to register, collect, file, or remit Louisiana tax can result in tax assessments, interest, and statutory penalties. The amount depends on the type and duration of the noncompliance, the tax involved, the return or payment missed, and the applicable Louisiana provisions. Because penalty formulas and administrative relief can change, do not rely on an assumed percentage; ask the Louisiana Department of Revenue for the current rule for the specific delinquency.
A practical compliance plan is to monitor Louisiana gross revenue and transaction counts, identify direct and marketplace sales separately, classify products, determine the destination parish, register promptly when required, file every assigned return, reconcile tax collected to tax remitted, and preserve exemption and sourcing records. If the seller has already missed an obligation, voluntary correction may be possible, but the best process depends on the account history and should be reviewed promptly with the Department or a qualified compliance service.

Frequently asked questions
Does a foreign seller need to collect Louisiana sales tax?
Yes, if the seller has Louisiana physical presence or, without physical presence, its gross revenue from sales delivered into Louisiana exceeds $100,000 during the previous or current calendar year. A qualifying marketplace facilitator may collect for marketplace sales, but the seller must still review direct sales and its remaining registration and recordkeeping obligations.
What is Louisiana’s economic nexus threshold for remote sellers?
The threshold is met when gross revenue from sales delivered into Louisiana exceeds $100,000 during the previous or current calendar year. Either test can trigger the remote-seller obligation.
How does a foreign seller register for Louisiana sales tax?
Register through the Louisiana Sales and Use Tax Commission for Remote Sellers portal. The Commission provides the single-return route for state and local taxes on qualifying remote sales. Confirm current application requirements and account instructions with the Louisiana Department of Revenue before registering.
Do marketplace facilitators collect Louisiana sales tax for sellers?
Generally, a marketplace facilitator that meets Louisiana’s applicable threshold must collect and remit state and local sales and use tax on taxable remote sales it facilitates or makes for marketplace sellers. A seller should verify exactly which transactions the facilitator covers and separately review direct sales.
What Louisiana sales tax rate should a foreign seller charge?
The seller should charge the current combined state and local rate applicable to the taxable sale and its properly sourced Louisiana delivery destination. Because parish and local rates and tax bases vary, there is no universal rate for every order. Check the Louisiana Department of Revenue’s current rate information.
When are Louisiana sales tax returns and payments due?
Louisiana remote-seller guidance states that the return and payment are due on or before the 20th day of the month following the close of the calendar-month reporting period. The account’s assigned filing frequency and current Department of Revenue instructions control, so verify the due date for the registered account.
How does Louisiana determine the correct parish sales tax?
Louisiana uses the delivery destination and applicable sourcing rules to determine the local jurisdiction and rate for a remote sale. Because Louisiana is a home-rule state, preserve the complete ship-to address and apply the current parish and local tax bases and rates rather than using only the state rate.
What are the penalties for not collecting or filing Louisiana sales tax?
Noncompliance can lead to assessments for unpaid tax, interest, and statutory penalties, with the amount depending on the violation and applicable law. The seller should confirm the current penalty calculation with the Louisiana Department of Revenue and address missed registration, returns, or payments promptly.
