Economic Nexus Laws by State: Louisiana

by Jennifer Dunn June 3, 2020

State laws on economic nexus vary and it can be hard to keep up if you’re doing business in multiple states.

As of May 7, 2020, the Louisiana Sales and Use Tax Commission for Remote Sellers announced the date remote sellers are required to register to collect sales tax.

Here’s all the information you need to know about economic nexus laws in Louisiana.

What is economic nexus in Louisiana?

With the South Dakota v. Wayfair Supreme Court ruling in 2018, states are now free to pursue sales tax from eCommerce businesses who have an “economic presence” in their state.

Significant presence or “nexus” was previously defined as having a physical presence (ex: a brick & mortar store, employee or inventory in a fulfillment center like FBA). But with this recent ruling, now this definition has been expanded to include economic activity in a state as well. This concept of triggering sales tax responsibility because of your economic activity in a state is now referred to as economic nexus.

Most importantly, what this means is that if you pass a state’s economic threshold for total revenue in that state and/or number of transactions in that state, you’re now legally required to register, collect and remit sales tax for that state.

Louisiana enacted an economic sales tax law on June 12, 2018, and in December, announced the enforcement date would be “a date to be determined in 2019.” Out-of-state sellers were promised “at least thirty days’ notice prior to the commencement of mandatory collection and remittance requirements.”

On May 7, 2020, that notice was given for July 1, 2020. Remote sellers must register a sales tax permit in Louisiana within 30 days of meeting economic nexus thresholds, and start collecting sales tax “no later than 60 days after surpassing” the economic nexus threshold, detailed below.

Louisiana further announced that they would provide guidance in the days leading up to July 1, 2020.

When did this Louisiana law go into effect or is it planned?

This law will go into effect July 1, 2020.

What about marketplace facilitator laws?

This announcement also noted that a Senate bill is under consideration to define and require marketplace facilitators (like Amazon, eBay, etc.) to collect and remit sales tax at the actual state and local sales tax rates to the state of Louisiana. This potential amendment would also go into effect July 1, 2020.

Louisiana would be joining 40 other states that currently have active marketplace facilitator laws in the U.S.

I’ve been collecting and remitting sales tax to Louisiana voluntarily. Now what?

Some remote sellers chose to voluntarily collect and remit at the statutory 8.45% sales tax rate prior to this enforcement date, rather than the actual rate in effect at each location.

The Louisiana Department of Revenue and the Sales and Use Tax Commission for Remote Sellers will contact these sellers later in the month with step-by-step details on the transition process. “No action is required until those direct marketers receive this correspondence.”

Direct marketers who don’t meet either of the economic nexus thresholds ($100,000 in sales or 200 transactions) may continue to collect and remit the single 8.45% rate.
