What is the Louisiana sales tax registration threshold?
The Louisiana sales tax registration threshold is $100,000, measured over the previous or current calendar year. Cross it and you must register for Louisiana sales tax with the Louisiana Department of Revenue. You then charge sales tax on sales to customers in Louisiana.
Do marketplace sales count toward this threshold?
Yes. Louisiana (sales tax) counts sales made through a marketplace facilitator toward the underlying seller's own threshold. The facilitator collects and remits the tax on those sales, so you are not paying it twice - but the volume still moves you toward the figure on this page, and you can be required to register on the strength of sales somebody else collected on. We have not been able to confirm this one against Louisiana (sales tax)'s own material. The published sources disagree, and where they disagree this data counts the sales, because counting is the answer that cannot hide a registration duty. Treat it as our safe default rather than as a finding, and check with Louisiana (sales tax) before relying on it.
Sales through a merchant of record such as Paddle, Polar or Lemon Squeezy are different again: those are the platform's own sales and count toward no threshold anywhere.
What's different about Louisiana
Louisiana collects state tax centrally but parishes administer their own local tax. The Louisiana Sales and Use Tax Commission for Remote Sellers handles both for remote sellers - register there, not with individual parishes.
State registration isn't the whole story
Louisiana is a home-rule jurisdiction: local cities and counties administer their own sales tax separately from the state. Registering with the state does not register you locally - check local requirements once you cross.
When do you need to register?
Economic nexus: once your sales into the state pass its threshold (commonly $100k or 200 transactions), you must register and collect that state's sales tax.
Deadline: Register before your next sale - many states apply nexus prospectively from the crossing.
