Louisiana E-commerce Sales Tax Nexus Guide — 2026

Updated

If your E-commerce business sells $100,000 into Louisiana in a calendar year, you have economic nexus and must register, collect, and remit Louisiana sales tax.

E-commerce sales tax basics in Louisiana

For a direct-to-consumer store (Shopify, WooCommerce, BigCommerce, or custom) shipping to Louisiana buyers, the economic nexus trigger is $100,000 in LA-destination revenue (effective 2023-08-01). Crossing that bar obligates registration, collection, and periodic filing.

Once registered, charge 5.00% state tax plus the applicable local rate — averaging 5.11% across Louisiana but varying by the buyer's shipping ZIP on most tangible personal property. Digital products, subscriptions, and professional services have different treatment — see the Louisiana SaaS page if you sell software or digital goods.

Registration + collection checklist

  1. Register with the Louisiana Department of Revenue for a sales tax permit.
  2. Configure your cart platform to collect tax at the destination rate. Enable LA in your tax settings.
  3. Charge the combined state + local rate at the customer's delivery address (most states source to ship-to, not ship-from).
  4. File returns on the cadence your DOR assigns (monthly, quarterly, or annually).
  5. Track your Louisiana-sourced revenue monthly so you know when you're approaching or below threshold for the next period.

Common mistakes e-commerce sellers make in Louisiana

  • Using origin-based rates (your HQ state's rate) instead of destination rates. Louisiana sources to the buyer's ship-to address — charge the LA rate, not your home state's.
  • Counting marketplace sales toward the Louisiana threshold. Amazon, Etsy, and eBay sales are usually excluded in Louisiana; check the specific rule before adding them to your nexus-tracking spreadsheet.
  • Waiting until year-end to register. If you cross $100,000 mid-year, you must begin collecting on sales made after the threshold-crossing date — back-tax exposure grows until you register.
  • Forgetting to file zero returns once registered. Missing filings trigger penalties even when you owe no tax.
