What is Louisiana's e-commerce sales tax in 2026?

Louisiana's 2026 e-commerce sales tax: out-of-state sellers collect once they cross $100,000 in Louisiana-destination revenue. As a remote seller, charge the 5.00% state rate plus any applicable local rate at the buyer's ship-to address.

Do I collect sales tax on every Louisiana order?

You collect Louisiana sales tax once you cross the economic nexus threshold ($100,000). Below threshold, you don't need to collect unless you have physical nexus (office, employees, inventory in Louisiana).

What rate do I charge for Louisiana e-commerce sales?

For sales shipped into Louisiana from out of state, charge the 5.00% state rate plus any applicable local rate at the buyer's ship-to address. Most e-commerce platforms (Shopify, WooCommerce) can apply destination rates automatically when you enable LA in tax settings. Sales that both begin and end inside Louisiana can follow a different sourcing rule in a minority of states — check with the Louisiana Department of Revenue if you are an in-state seller.

Do I need to collect sales tax on shipping in Louisiana?

It depends on state-specific rules. Many states tax shipping when the product is taxable; some states exempt shipping if separately stated. Check Louisiana's specific policy or use a tax service that encodes the rule.

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

Register with the Louisiana Department of Revenue for a sales tax permit.
Configure your cart platform to collect tax at the destination rate. Enable LA in your tax settings.
As a remote seller, charge the combined state + local rate at the customer's delivery address — interstate sales are sourced to the destination, not to where you ship from.
File returns on the cadence your DOR assigns (monthly, quarterly, or annually).
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. A sale shipped from outside Louisiana into Louisiana is sourced to the buyer's delivery address, so charge the LA rate, not your home state's. Intrastate sales are a separate question: a minority of US states apply origin sourcing to sales that both begin and end in-state, so if your business is located in Louisiana, confirm the intrastate rule with the Louisiana Department of Revenue before configuring your cart.
Guessing at how marketplace sales count toward the Louisiana threshold. States split on this — some let a seller exclude sales a registered marketplace facilitator already collected on, others require those sales to be included in the threshold test even though the marketplace remits the tax. Read Louisiana’s own rule on the Louisiana marketplace facilitator page before adding or removing them from your nexus-tracking spreadsheet.
Waiting until year-end to register. Registration and collection deadlines run from the threshold-crossing date, and the length of that grace period is set by each state — some require collection on the very next transaction, others allow until the first day of a later month. Check Louisiana’s deadline with the DOR as soon as you cross $100,000; back-tax exposure accrues for every day you sell unregistered.
Forgetting to file zero returns once registered. Missing filings trigger penalties even when you owe no tax.
