What is trailing nexus?

Most states make you keep filing for a while after you drop below their threshold. California runs through the next full calendar year. Texas uses a rolling twelve months. We track each state's rule so you cancel on the right date, not too early.

Will I get in trouble for canceling a permit?

Not if you do it in the right order. We file every outstanding and final return first, then guide the cancellation. The real risk is canceling early or skipping a final return, which is exactly what we prevent.

Which platforms do you support?

Amazon, Shopify and WooCommerce, with BigCommerce, Etsy, Walmart and eBay supported through manual entry. You can also enter your states by hand on any platform.

Do you file my returns?

Yes. During the wind-down we file the zero-dollar returns so nothing lapses, and once you're deregistered in a state there's nothing left to file.

How is this different from Avalara or TaxJar?

They help you register and file more. We help you deregister and file less. We only charge for the states you keep.

No. TrailingZero is software that flags deregistration opportunities and handles filings. For complex situations we tell you when to bring in your accountant.

Is TrailingZero live?

Yes. Free audits are live now — run yours in minutes. Connect a store read-only or enter your registered states by hand to see which you can cancel and what it saves.

Short answer

Yes — once your nexus has genuinely ended. Canceling your Louisiana sales tax registration makes sense if you have consistently fallen below the $100,000 gross revenue threshold in both the current and prior calendar year and have no physical presence in the state. The catch is that Louisiana has not published a clear trailing nexus rule, so it is safest to remain registered through the end of the calendar year in which you last exceeded the threshold, file a final return for the last active period, and then submit Form R-3406 to the Department of Revenue by mail, fax, or email — note that failure to file this form will result in estimated assessments continuing to accrue.

Do you still have nexus in Louisiana?

You can only cancel once your obligation has ended. Two things create it: physical presence (inventory, an employee, an office) and economic nexus (crossing $100,000 in sales).

For Amazon FBA and 3PL sellers the sneaky one is physical nexus: storing inventory in Louisiana creates it. Standard physical nexus rules apply: employees, offices, warehouses, or inventory stored in Louisiana creates physical nexus. If that inventory has since left the state, your physical nexus may have already ended even though the registration is still open.

Trailing nexus in Louisiana

Louisiana has not published explicit statutory or regulatory guidance defining a trailing nexus period. The state's economic nexus measurement looks at the 'previous or current calendar year,' implying that a seller who exceeded the threshold in the prior calendar year retains nexus obligations through at least the end of that year. However, LDR has not issued definitive rules specifying how long after dropping below the threshold a seller must continue to collect, meaning the practical trailing period is unconfirmed. Best practice is to remain registered through at least the end of the calendar year in which the threshold was last exceeded, and to confirm with LDR before canceling.

No specific statutory restrictions on cancellation have been identified beyond the general requirement to file Form R-3406 and a final return. Louisiana has not published a rule barring deregistration. However, absence of explicit guidance means the state could assert ongoing obligations; consult LDR directly before canceling.
