Louisiana uses an economic nexus standard for remote ecommerce and cross‑border sellers: if your sales into Louisiana cross the state’s sales threshold, you are required to register, collect, and remit Louisiana sales and use tax even without physical presence. For remote sellers, registration is handled through the dedicated Louisiana Sales and Use Tax Commission for Remote Sellers
This page walks you through how Louisiana economic nexus works, when you must register, how marketplace sales affect your obligations, and what to do if you already have past exposure. Sales Tax Compliance USA is a done‑for‑you service staffed by specialists: when the rules are unclear or depend on your specific facts, we will review your situation and confirm details directly with the Louisiana Department of Revenue or the Remote Sellers Commission before we act on your behalf.
What is economic nexus in Louisiana?
Economic nexus in Louisiana is a rule that requires out‑of‑state and online sellers to collect Louisiana sales and use tax once their sales into the state exceed a specified threshold, even if they have no physical presence in Louisiana. For remote sellers, the state applies a sales‑based threshold
Current guidance consistently describes Louisiana’s economic nexus trigger for remote sellers as $100,000 in sales into Louisiana
Once you have economic nexus, you are treated as a seller required to collect both state and applicable parish‑level sales and use tax on taxable sales delivered to Louisiana customers. For remote sellers without physical locations in the state, the Remote Sellers Commission filing system allows you to file a single combined return that covers both state and local tax obligations, instead of registering separately with each parish. Our team uses that structure to minimize your friction while ensuring that state and local requirements are both met.
Louisiana economic nexus threshold and when it applies
Most current Louisiana sales tax guidance for remote ecommerce sellers states that economic nexus is triggered when a remote seller’s Louisiana‑destination sales reach or exceed $100,000
Importantly, the threshold looks at your sales into Louisianamarketplace‑facilitated sales
As a practical rule of thumb, if your direct‑to‑consumer site, your own app, and your non‑marketplace channels together ship more than roughly $100,000 of product or services to Louisiana customers in a year, you should assume you are close to or over the threshold and plan for registration. Sales Tax Compliance USA can review your sales data, distinguish marketplace‑collected transactions from your own, and advise whether you have crossed nexus under the current interpretation, then verify that position with Louisiana for you.
When to register for Louisiana sales tax
Remote seller guidance that discusses the Louisiana Sales and Use Tax Commission for Remote Sellers consistently states that registration is required within 30 days after you exceed the economic nexus threshold
If you do not have physical presence in Louisiana and your nexus arises solely from economic activity, you register through the Remote Sellers Commission portal, not through each parish. Remote seller guides instruct applicants to go to the dedicated site (often cited as remotesellers.louisiana.gov), choose the remote seller registration option, and complete an online application with your legal entity information, ownership, and key contacts. After submission, the Commission issues account credentials you will use to file centralized returns. Our team handles this entire process for you, including gathering the required documentation, submitting the application, and monitoring for the approval notice. For businesses that already have a physical location or warehouse
Louisiana sellers with economic nexus must file periodic sales and use tax returns and remit tax by the state’s due dates. For remote sellers using the Louisiana Remote Sellers Commissionmonthly
Recent updates describing Louisiana’s parish filing system explain that combined state and local returns for certain accounts are due by the 20th of the month following the reporting period
In practice, you will need to track taxable sales, exempt sales, tax collected, and marketplace‑reported transactions for each period. Remote seller guidance emphasizes that Louisiana is a destination‑based, home‑rule state
Economic nexus did not replace physical nexus in Louisiana; it simply added another way to create an obligation to collect tax. Guidance describing Louisiana nexus makes clear that physical presence still creates nexus
Some remote seller analyses specifically note that “physical presence still matters” and discuss scenarios where a seller has a Louisiana warehouse or uses an in‑state third‑party logistics provider to store inventory. In those cases, nexus arises from the physical presence even if your direct Louisiana sales are below $100,000. The resulting registration and filing requirements can differ from pure remote‑seller status. For example, parish‑level accounts may be required, and combined state‑parish monthly filing through Parish E‑File may be enforced for accounts tied to physical locations. Because physical and economic nexus can overlap, we do not rely solely on your sales volume. When you work with Sales Tax Compliance USA, our team maps your facilities, inventory, employees, and contractors to Louisiana. If any of those touchpoints exist, we review the current Department of Revenue and parish rules to determine whether physical nexus is already present, and then advise the appropriate registration path. Where the rules are unclear, we contact the state directly and base our advice on their guidance rather than on assumptions. Louisiana applies a marketplace facilitator regimedo not count Other analyses aimed at business owners reiterate that “marketplace‑facilitated sales do not count toward the individual seller’s $100,000 threshold if the marketplace facilitator is already collecting Louisiana tax on those sales,” and that in that case only your own direct sales count toward nexus. However, the details depend on whether your marketplace is officially registered as a facilitator in Louisiana, how your agreements are structured, and whether any of your marketplace transactions fall outside the facilitator’s tax collection arrangement. If, for example, you own a shop on a marketplace that is registered as a facilitator, but you also make direct offline sales to Louisiana customers, only the offline sales would typically count toward your threshold—but confirming this with Louisiana is still prudent. When we evaluate your Louisiana nexus, we separate your revenue into facilitated marketplace channels vs. direct channels
Louisiana’s structure for sales and use tax is distinctive because it is a home‑rule statestate rate and applicable parish rates
Louisiana generally applies destination‑based sourcing
Because parish rates and local rules can change and can be highly granular, we do not quote a single “Louisiana rate” as if it were uniform. Instead, we treat the state rate plus the parish‑specific rate for each destination as the relevant figure, and we rely on up‑to‑date rate data and official parish or Commission guidance when calculating tax on your transactions. Sales Tax Compliance USA manages those calculations for you, mapping your sales to the correct parish codes and ensuring that your returns reflect the currently effective combined rates rather than outdated averages. Once your direct sales into Louisiana meet or exceed the economic nexus threshold—or once you have physical nexus—you should assume you have a current obligation to register and begin collecting tax on taxable sales. Remote seller guidance indicates that registration with the Louisiana Sales and Use Tax Commission for Remote Sellers must occur within 30 days after exceeding the threshold and that collection must begin within a prescribed period after registration. For physical nexus or parish‑level accounts, similar prompt registration expectations apply. The safest course is to start the registration process as soon as you realize your threshold has been met. After registration, your next steps are to configure your checkout
Sales Tax Compliance USA handles this transition for you. We identify when your nexus began, determine the correct registration path (Remote Sellers Commission, parishes, or both), coordinate with Louisiana to complete registration, and then implement collection settings in your storefront and payment flows based on current Louisiana rules. Where the law leaves room for interpretation—for example, on the treatment of certain digital products or services—we put those questions directly to the Department of Revenue or the Commission and structure your compliance around their answers rather than assumptions. For remote sellers whose nexus arises from economic activity alone, the key step is obtaining approval from the Louisiana Sales and Use Tax Commission for Remote Sellers
These guides often reference contact details for the Commission, including telephone numbers and an email address, to be used when questions arise or when applications require clarification. While specific contact information is helpful, the most important point is that the Commission is a dedicated body separate from the standard Louisiana Department of Revenue registration channels and exists specifically because local parishes normally administer their own taxes. Remote sellers use the Commission to avoid registering and filing in every parish individually. If you have physical operations

If you already have past exposure—uncollected tax on Louisiana sales during periods when you had nexus but were not registered—there are several potential paths: you can register and start filing prospectively
Louisiana’s combination of economic nexus, home‑rule parish administration, and a separate Remote Sellers Commission portal makes the state unusually complex for ecommerce and cross‑border sellers. You must track your direct Louisiana sales carefully to know when you cross the economic nexus threshold, distinguish marketplace‑facilitated sales from your own, account for both state and parish rates under destination‑based sourcing, and stay on top of monthly filing and payment deadlines. At the same time, you need to avoid guessing about thresholds, registration timelines, or penalty rules: the safest and most cost‑effective path is to build your compliance on what Louisiana is currently telling taxpayers. Sales Tax Compliance USA is a done‑for‑you service
If you suspect you have met Louisiana’s economic nexus threshold or you already received a notice from the state or a parish, we can review your situation and outline your options, including bringing you into compliance going forward and exploring ways to address past exposure. In a state like Louisiana, where local parishes wield significant authority and the Remote Sellers Commission centralizes obligations for remote sellers, having a team that lives inside these rules every day can be the difference between smooth compliance and costly missteps. Economic nexus in Louisiana is a rule that requires an out‑of‑state or online seller to collect Louisiana sales and use tax once its sales into the state exceed the state’s economic threshold, even without physical presence. For remote sellers, current guidance describes a revenue‑based threshold and centralized registration through the Louisiana Sales and Use Tax Commission for Remote Sellers. Once that threshold is crossed, you must register, begin collecting tax on taxable sales to Louisiana customers, and file periodic returns. Business‑facing guidance consistently describes Louisiana’s economic nexus threshold for remote sellers as $100,000 in sales delivered to Louisiana customers during the current or prior calendar year. Some older or less up‑to‑date resources still reference a 200‑transaction test, but more recent analyses focused on the Remote Sellers Commission treat the $100,000 revenue threshold as the operative trigger. If your sales are near this level, you should confirm the current threshold directly with the Louisiana Department of Revenue or the Remote Sellers Commission, or work with us and we will do that for you. Remote seller guidance states that once you exceed Louisiana’s economic nexus threshold, you must register with the Louisiana Sales and Use Tax Commission for Remote Sellers within 30 days and begin collecting tax within a defined period thereafter. If you have physical presence—such as a warehouse or office in Louisiana—you may need to register even before reaching the economic threshold, typically with the Department of Revenue and relevant parishes. Because deadlines and account types depend on your circumstances, you should confirm them with Louisiana or engage us to review and validate them for you. Current commentary indicates that many Louisiana sellers, particularly those using parish filing systems or the Remote Sellers Commission, file sales and use tax returns on a monthly basis and that combined state‑parish returns are due around the 20th of the following month. However, actual filing frequency is assigned by Louisiana based on your registration and sales volume and can be monthly, quarterly, or annual. You should rely on your account approval letter and the state’s current filing calendar, or ask us to confirm and set up your filing schedule. Yes. Physical presence—such as owning or leasing property, storing inventory, having employees, or operating a store or office in Louisiana—still creates sales tax nexus even if you do not meet the economic threshold. In those cases, you may need to register at the state and parish level and collect tax regardless of your revenue into Louisiana. We examine your physical footprint and confirm with the state which activities trigger nexus in your situation. Current remote seller guidance explains that marketplace‑facilitated sales where the marketplace is registered as a facilitator and collects and remits Louisiana tax generally do not count toward the individual seller’s $100,000 economic nexus threshold; only the seller’s direct sales are considered. However, whether your marketplace is treated as a facilitator and how specific sales are counted can depend on your agreements and Louisiana’s current policies, so you should confirm this directly with the Remote Sellers Commission or work with us to do so. Missing Louisiana sales and use tax filing or payment deadlines can result in added interest and penalties on the tax due, and repeated non‑compliance can increase the likelihood of notices or audit activity. The specific penalty rates and interest calculations are set by Louisiana law and depend on how late a filing or payment is. If you have missed deadlines, the best step is usually to file and pay as soon as possible and consider whether to contact Louisiana to discuss resolving the issue; we can help assess your exposure and coordinate with the state. To obtain authorization to collect Louisiana sales tax as a remote seller, you generally register through the Louisiana Sales and Use Tax Commission for Remote Sellers by completing an online application with your business information. After your application is processed, the Commission issues account credentials and confirmation, which function as your permit for centralized collection and filing. If your nexus arises from physical presence rather than remote activity, you may have to register through the Louisiana Department of Revenue and relevant parishes instead; we determine the correct path and handle the registrations for you. Because Louisiana is a home-rule state, local jurisdictions there can administer and audit their own tax separately from the state, which is where doing this yourself usually stops being viable.

Key Louisiana sales tax nexus and filing differences for remote sellers vs. sellers with physical presence
Aspect
Remote seller using Louisiana Remote Sellers Commission
Seller with physical presence in Louisiana
Primary nexus trigger
Economic nexus based on sales into Louisiana (commonly described as $100,000 in Louisiana‑destination sales in current or prior calendar year).
Physical presence (property, inventory, employees, or offices in Louisiana), often regardless of economic nexus threshold.
Registration authority
Registers through the Louisiana Sales and Use Tax Commission for Remote Sellers via its online portal.
Registers with the Louisiana Department of Revenue and, as needed, with individual parishes or via parish filing systems like Parish E‑File.
Scope of tax collected
Collects both state sales and use tax and applicable local parish taxes through a centralized Remote Sellers Commission return.
Collects state sales and use tax plus parish‑level taxes based on local registration; combined state‑parish filing may be required for certain accounts.
Marketplace sales treatment for nexus
Commentary indicates marketplace‑facilitated sales where the marketplace collects and remits Louisiana tax generally do not count toward the seller’s $100,000 threshold; only direct sales are considered.
Marketplace rules still apply, but physical presence often creates nexus independently of economic threshold, so marketplace sales are less central to the nexus analysis.
Typical filing frequency
Frequently described as monthly filing through the Remote Sellers Commission, with returns covering both state and local taxes; exact frequency confirmed from account details.
Often monthly for accounts with parish‑level obligations and combined state‑parish returns; frequency can vary based on state and parish assignment and must be confirmed from registration documents.
Sourcing of sales
Destination‑based: tax rate determined by delivery address, with Remote Sellers Commission return allocating tax among parishes.
Destination‑based for shipped sales; may also collect tax on over‑the‑counter sales at the physical location’s parish rate.
Main compliance risk if unmanaged
Crossing the economic nexus threshold without registering or collecting, leading to tax, interest, and penalties on uncollected sales.
Operating with physical presence but unregistered or under‑registered, missing returns or under‑reporting parish‑level obligations, increasing notice and audit exposure.
