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 Missouri sales tax registration makes sense once your trailing 12-month taxable sales into Missouri have been clearly below $100,000 for a full measurement period (evaluated quarterly), meaning you have no current or prior-year nexus exposure. The main catch is Missouri's final-return requirement: you must file a closing return (Form 53-1 or vendor's use tax return) within 15 days of discontinuing sales, and submit Form 5633 (Final Report) to officially close the account — missing that window can leave you technically registered and obligated to keep filing zero returns.

Do you still have nexus in Missouri?

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 Missouri creates it. Storing inventory or goods in a Missouri warehouse or fulfillment center (e.g., Amazon FBA) 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 Missouri

Missouri's vendor's use tax obligation continues as long as the seller is 'engaged in business activity within Missouri.' The $100,000 threshold is evaluated on a rolling preceding 12-month basis at each quarter end, so a seller must confirm they are below threshold for a full measurement period before deregistering. No explicit statutory trailing-nexus duration (e.g., 'remainder of year plus one year') has been published by the DOR — the practical effect of the quarterly rolling lookback means nexus continues at least through the quarter following the last period in which threshold was met.

Seller must file a final return (Form 53-1 or final vendor's use tax return) within 15 days of closing/discontinuing. Form 5633 (Final Report) is used to officially notify DOR of business/location closure.
