Why Louisiana Sales Tax Matters
Louisiana is one of the largest ecommerce markets in the United States and home to a major concentration of Amazon FBA fulfillment centers across Carencro, Shreveport.
If you sell through Amazon, Shopify, Walmart, or any other marketplace, Louisiana’s economic nexus rules mean you can owe sales tax even if your company is registered outside the U.S. Louisiana sales tax nexus is established when a business has a significant connection to the state — either by exceeding a sales threshold or through inventory, employees or contractors physically located in Louisiana.
Failing to register or file properly can result in:
- State tax penalties and backdated interest
- Account suspensions on Amazon, Walmart or Shopify
- Rejection of future foreign business registrations
- Criminal liability for unremitted tax above $1,500
Key Takeaways:
- $100,000 in gross Louisiana revenue over the preceding 12 months creates economic nexus.
- Storing FBA inventory in any Louisiana warehouse creates physical nexus immediately — no revenue threshold applies.
- Marketplace facilitator laws do not exempt you from registration if you also sell through your own website or have physical presence.
- Louisiana is not a Streamlined Sales Tax member — you must register directly with the Louisiana Department of Revenue (and Louisiana Sales and Use Tax Commission for Remote Sellers).

Understanding Louisiana Sales Tax
Louisiana sales tax is a consumption tax applied to retail sales of tangible personal property and most taxable services. The state imposes a base rate of 5.00%, and local jurisdictions (cities, counties, transit authorities and special purpose districts) can add up to 8.50% on top, capped at a combined maximum of 13.50%.
Sales tax is collected by sellers with nexus in Louisiana and remitted to the Louisiana Department of Revenue (and Louisiana Sales and Use Tax Commission for Remote Sellers) (Louisiana DOR).
The Sales Tax Structure
Louisiana uses mixed — origin-based for in-state louisiana dealers (collect at your business location’s rate); destination-based for remote sellers via the louisiana sales and use tax commission for remote sellers (single state+parish return). Remote sellers can elect to collect a single statewide local use tax rate of N/A% (for N/A) instead of tracking the rate at every individual delivery address — making the combined rate a flat 8.00% on every Louisiana sale.
| Location | Combined Rate | Breakdown |
|---|---|---|
| New Orleans (Orleans Parish) | 9.45% | 5.00% state + 4.45% Orleans Parish + city |
| Baton Rouge (East Baton Rouge Parish) | 9.95% | 5.00% state + 4.95% local |
| Shreveport (Caddo Parish) | 9.05% | 5.00% state + 4.05% local |
| Lafayette (Lafayette Parish) | 9.45% | 5.00% state + 4.45% local |
👉 Use the Louisiana DOR City Sales and Use Tax Rates to confirm any local rate.
Economic Nexus Thresholds in Louisiana
Louisiana enforces economic nexus for both domestic and foreign sellers. You must register for a Louisiana Sales Tax Account (state) + parish-level accounts if your total Louisiana revenue is $100,000 or more in the current or previous calendar year.
What counts toward the threshold:
- Gross revenue from taxable and non-taxable sales of tangible personal property and services delivered into the state
- Sales made through marketplace providers (Amazon, Walmart, Etsy, eBay)
- Separately stated handling, transportation and installation charges
- Sales for resale and sales to tax-exempt entities
This applies even if you:
- Operate entirely outside the U.S.
- Sell exclusively via Amazon, Walmart or Shopify
- Have no employees or offices in the state
Example: A UK-based Shopify store ships $600,000 of products into Louisiana between June 1, 2025 and May 31, 2026. The threshold is crossed in May. The seller must obtain a permit and begin collecting and remitting tax by September 1, 2026 (the first day of the fourth month after crossing).
Termination: Once registered, you can only stop collecting if your Louisiana revenue stays below $100,000 for 12 consecutive months — a single low quarter does not lift the obligation.
Physical Nexus Triggers in Louisiana
Even without crossing the $100,000 sales threshold, your business has physical nexus in Louisiana if you:
- Store inventory in a Louisiana Amazon FBA centre or 3PL warehouse (this is the most common trigger for FBA sellers)
- Employ staff or contractors in the state — including delivery agents, installers or sales reps
- Attend trade shows or temporary retail events (even a single day creates exposure)
- Use in-state affiliates or influencers who actively promote your products
- Use a drop-shipper that fulfills orders from inventory held in Louisiana
FBA inventory in Carencro or Shreveport creates physical nexus immediately — but importantly, in-state physical nexus typically requires PARISH-by-parish registration (60+ parishes). Remote sellers escape this by using the Louisiana Remote Sellers Commission single-return system. SaaS sellers who didn’t update their tax engines for the January 1, 2025 base expansion may have substantial backdated exposure.

Obtaining a Louisiana Sales Tax Permit
The Louisiana Department of Revenue (and Louisiana Sales and Use Tax Commission for Remote Sellers) (Louisiana DOR) administers all sales tax registration in Louisiana. Most applications are filed online through the Comptroller eSystems portal.
How to register: Submit Online application via Louisiana Sales and Use Tax Commission for Remote Sellers (for remote sellers, single state+parish return) or LaTAP for in-state dealers through the eSystems portal. You will need your legal business name, any DBA, federal EIN, state of formation, business address, NAICS code, and identification for the responsible party. Online filing typically takes 20–40 minutes.
Cost and timeline: Free. Permits are typically issued within 5–10 business days for online applications after a complete application is submitted. Once approved, remote sellers receive a single Louisiana Remote Seller account that covers both state and parish (local) tax in one return. In-state dealers receive separate state + parish accounts.
Understanding Louisiana sales tax nexus: Before registering, confirm whether your business has nexus through physical presence (inventory, employees, contractors) or through the $100,000 economic nexus threshold. Out-of-state sellers and marketplace sellers should pay particular attention — even businesses with no physical presence in Louisiana must register if they meet the threshold.
Foreign Seller Louisiana Sales Tax Registration Requirements
Follow these steps to obtain your Louisiana Sales Tax Account (state) + parish-level accounts as a non-U.S. business:
- Confirm your business type (foreign LLC, corporation, sole proprietor or other entity).
- Apply online via the Louisiana Department of Revenue (and Louisiana Sales and Use Tax Commission for Remote Sellers), or email Online application via Louisiana Sales and Use Tax Commission for Remote Sellers (for remote sellers, single state+parish return) or LaTAP for in-state dealers to (international sellers register through salestaxonline.dor.louisiana.gov; contact LA Remote Sellers Commission at 225-219-7462 if you cannot complete registration without a U.S. SSN) if you do not yet have an eSystems account.
- Prepare the required documents:
- Federal EIN (Employer Identification Number)
- Formation or incorporation certificate
- Passport or government ID of the responsible officer
- Foreign business address (a U.S. address is not required)
- Wait for approval (usually within 5–10 business days for online applications).
- Begin collecting and remitting Louisiana sales tax on all taxable sales delivered into the state.
After registration you must file a Louisiana sales and use tax return on your assigned schedule (monthly, quarterly or annual), even if you have zero sales for a period.

Filing & Payment Rules
Once registered you must file Louisiana sales and use tax returns through the Louisiana DOR’s Webfile portal, EDI, or TEXNET (for high-volume payers).
| Requirement | Details |
|---|---|
| Filing Frequency | LA DOR / Remote Sellers Commission assigns frequency based on liability: monthly (default for higher-volume sellers), quarterly, or annual for smaller sellers. |
| Due Dates | 20th of the month following the reporting period. |
| Payment Methods | Electronic filing through the Louisiana Sales and Use Tax Commission for Remote Sellers (single state+parish return) or LaTAP (in-state dealers + individual parish portals) is mandatory for most sellers. Payment via ACH-debit, ACH-credit, or credit card. |
| Discount for Timely Filing | Louisiana pays a vendor compensation of approximately 1.05% on state tax timely collected and remitted, capped at approximately $1,500 per month. Verify current rates with LA DOR. |
| Penalties | 5%/month late-filing penalty (max 25%); up to 100% late-payment penalty in extreme cases; 0.75%/month interest. |
- Sales tax automation (or a done-for-you service) helps streamline the filing, payment and reconciliation process — particularly important for international sellers managing returns in multiple states simultaneously.
⚠️ Noncompliance can result in permit revocation, audit assessments, account holds with marketplaces, and — for unremitted tax of $1,500 or more — criminal prosecution.
Marketplace Facilitator Laws in Louisiana
Since July 1, 2020, Louisiana requires marketplace facilitators (Amazon, eBay, Walmart, Etsy, TikTok Shop) to collect and remit sales tax on behalf of third-party sellers.
However, this does not remove your obligations as a seller:
- If you have physical presence in Louisiana (FBA inventory, employees, contractors, office), you must still register and file — even if 100% of your sales are through marketplaces.
- If you also sell through your own Shopify, WooCommerce or branded site, you are responsible for collecting and remitting tax on those direct sales.
- Marketplace sales still count toward the $500,000 economic nexus threshold.
- You must keep records of all marketplace sales for at least 4 years for audit purposes.
2025–2026 update: Three big Louisiana 2025-2026 changes: (1) State rate INCREASED from 4.45% to 5.0% effective January 1, 2025 (HB 10 reform). Drops to 4.75% on January 1, 2030. (2) HB 10 also added SaaS, prewritten software access and digital products to the sales tax base effective January 1, 2025 — major change for software vendors. (3) The 200-transaction threshold was repealed August 1, 2023 — now $100K only. (4) Louisiana has a UNIQUE single-return system for remote sellers via the Louisiana Sales and Use Tax Commission, vastly simpler than registering with each of the 60+ parishes individually.
Example: A South African Amazon FBA seller with $600,000 in Louisiana sales (all via Amazon) and inventory stored in Houston must register and file zero-tax marketplace returns — because Amazon already collected the tax, but the Louisiana DOR still expects the seller to report total sales activity due to physical nexus.
Sales Tax vs. Use Tax
Louisiana imposes both sales tax and use tax:
- Sales Tax: Charged by sellers on retail sales delivered within Louisiana.
- Use Tax: Owed directly by the buyer when sales tax was not collected at the point of sale — most commonly on out-of-state or online purchases of taxable goods. The use tax rate equals the sales tax rate at the buyer’s location.
If your business buys equipment, fixtures or supplies from outside Louisiana for use within the state, you may owe use tax. Remote sellers who elect the single local use tax rate collect a flat N/A% local rate plus the 5.00% state rate, regardless of the delivery address.
Louisiana Sales Tax Filing & Due Dates
Filing frequency is assigned by the Comptroller based on your prior-year tax liability:
- Monthly — high-volume sellers
- Quarterly — most mid-sized sellers
- Annual — low-activity sellers
Returns are due 20th of the month following the reporting period.
Discounts and incentives for filing on time:
Louisiana pays a vendor compensation on state sales tax timely collected and remitted. Rates and caps have been amended multiple times in the 2024–2025 reform cycle — confirm the current cap with LA DOR before relying on it for cash-flow planning.
Late filings incur:
Late filing: 5% per month (capped at 25%). Late payment: graduated up to 100% of unpaid tax depending on duration. Negligence and fraud carry escalated penalties under Louisiana Revised Statutes §47:1602. Interest accrues at 0.75% per month.
Louisiana Sales Tax Exemptions
Not every sale into Louisiana is taxable. The most common exemptions for ecommerce sellers are:
- Most unprepared groceries (bread, milk, eggs, produce, flour, sugar) — but candy, soft drinks, energy drinks and individual snack portions are taxable
- Prescription medications
- Sales to U.S. government agencies and qualifying nonprofits
- Resale purchases made with a valid resale certificate
- Annual Sales Tax Holiday — Louisiana runs a Second Amendment Sales Tax Holiday in early September on firearms, ammunition and hunting supplies. The general back-to-school holiday was repealed in 2018.
Taxability quirks for online sellers:
- Shipping: Yes when shipping a taxable item; bundled shipping into a taxable price is fully taxable
- SaaS: Yes — effective January 1, 2025 under HB 10, Louisiana taxes SaaS, prewritten software access and digital products. SaaS vendors who treated LA like a non-SaaS state through 2024 may have backdated exposure
- Digital goods: Yes — effective January 1, 2025 under HB 10, digital goods (e-books, downloadable music, streaming, apps, in-game codes) are taxable in Louisiana — e-books, downloadable music, software and streaming follow the same rules as their physical equivalents
- Clothing: Yes — clothing is taxable in Louisiana at the full combined rate (no general exemption)
Always keep valid exemption certificates on file — the Comptroller frequently audits remote sellers and disallows undocumented exemptions.
Sales Tax for Online Sellers (Amazon, Shopify, Walmart)
For online sellers, Louisiana compliance depends on your fulfillment model and sales channels:
- Marketplace facilitators like Amazon, Walmart, Etsy and eBay collect and remit Texas sales tax automatically on sales made through their platforms.
- Direct Shopify, WooCommerce or BigCommerce sellers must register, collect and remit tax themselves — Shopify is not a marketplace facilitator (except for Shop App orders).
- If you sell through both, you must report all sales on your Texas return — including marketplace sales — and back out the marketplace-collected portion as deductions.
- FBA sellers: Louisiana hosts Amazon fulfillment centers in Carencro and Shreveport, anchoring central southern distribution. If Amazon stores even one unit of your inventory in Louisiana, you have physical nexus and must register, regardless of revenue.
Tip: Combine marketplace and direct sales under one Comptroller filing to avoid reporting discrepancies that trigger audits.
Calculating and Remitting Sales Tax
To calculate the correct tax on a Texas sale:
- Identify the delivery address rate using the Comptroller City Sales and Use Tax Rates — or, as a remote seller, elect the flat N/A% single local use tax rate for simplicity.
- Multiply your taxable sales by the combined rate. Sales tax applies to most tangible personal property; most pure services are not taxable, but data processing, telecommunications and several other named services are.
- Round to the nearest cent.
For example, a $100 taxable sale at the maximum combined 13.50% rate generates $13.50 in sales tax.
To eliminate the manual work entirely, Sales Tax Compliance USA takes over the full collect→reconcile→file→remit cycle for you. One fee, no software for you to learn.
Penalties & Risks for Noncompliance
Ignoring Louisiana nexus obligations is expensive. The Louisiana DOR routinely audits both U.S. and foreign sellers using Amazon FBA inventory reports, Shopify data, marketplace 1099-K filings and IRS information sharing.
| Violation | Penalty |
| Late filing of return | 5% per month (maximum 25%) |
| Late payment of tax | Graduated, up to 100% in extreme cases |
| Interest on unpaid tax | 0.75% per month |
| Negligence | Additional 5% of tax owed |
| Fraud | Up to 50% additional penalty plus criminal liability under Louisiana Revised Statutes §47:1602 |
🚫 Amazon, Walmart or Shopify may suspend your account if Louisiana notifies them of a registration deficiency. Don’t risk your U.S. operations — register before the Comptroller contacts you.
Louisiana is not a member of the Streamlined Sales Tax Agreement — you cannot use the multi-state SSTRS shortcut. Each registration is filed directly with the Comptroller.

FAQs for Louisiana Sellers
1. Do I need to register if Amazon already collects Louisiana sales tax for me?
If 100% of your LA sales are through certified marketplace facilitators (Amazon, Walmart, Etsy, eBay) AND you have no physical presence in LA, you generally do NOT need to register — Louisiana excludes marketplace sales from the $100,000 economic nexus threshold. But if you also sell on your own Shopify and exceed $100,000 in those direct sales, you must register through the Louisiana Sales and Use Tax Commission for Remote Sellers. And FBA inventory in Carencro or Shreveport creates physical nexus immediately.
2. Why does Louisiana have two separate registration systems?
Historically, Louisiana required sellers to register and file separately with each of 60+ parishes — operationally impossible for ecommerce. To fix this for remote sellers, the state created the Louisiana Sales and Use Tax Commission for Remote Sellers, which lets you file ONE return covering state + all parishes. In-state dealers (with physical presence) typically still register parish-by-parish via LaTAP. Cross-border sellers should use the Remote Sellers Commission wherever possible.
3. Can I register for Louisiana sales tax without a U.S. address?
Yes. The Louisiana Sales and Use Tax Commission for Remote Sellers accepts foreign business addresses. You will need a Federal EIN. Sales Tax Compliance USA can obtain the EIN and complete the registration for foreign entities as part of our service.
4. Did Louisiana really raise the state rate in 2025?
Yes — under HB 10 reform, the state rate increased from 4.45% to 5.00% effective January 1, 2025. The increase is scheduled to drop back to 4.75% on January 1, 2030. Combined rates can now exceed 13.5% in some Louisiana parishes.
5. Is SaaS taxable in Louisiana?
Yes — effective January 1, 2025, Louisiana taxes SaaS, prewritten software access, and digital products (e-books, music, streaming) under HB 10. SaaS vendors who treated LA like a non-SaaS state through 2024 may have multi-month backdated exposure. Update your tax engine and review historical filings.
