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 Kansas sales tax permit makes sense if you have dropped below $100,000 in Kansas sales for a full calendar year and have no physical presence in the state, since continuing to be registered means you must file zero returns every period or face penalties. The catch is that Kansas has no formally published trailing nexus rule, so you should confirm with KDOR that your nexus has lapsed before submitting Form CR-108 — and you must have all returns filed and taxes paid before closure will be approved.

Do you still have nexus in Kansas?

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 Kansas creates it. Physical presence — including employees, offices, warehouses, inventory stored in-state (e.g., Amazon FBA), or affiliated representatives — creates nexus regardless of sales volume, at thresholds lower than economic 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 Kansas

Kansas does not have a formally codified trailing nexus statute for remote sellers. The threshold rule creates a de facto trailing period: if a seller exceeded $100,000 in the prior calendar year, nexus (and collection obligation) continues through the entire current calendar year, regardless of current-year sales volume. Once a full calendar year passes with sales remaining below $100,000, the seller may seek to cancel the permit. Kansas has not published an explicit trailing nexus policy document beyond this threshold measurement rule.

Seller must ensure all returns are current and all taxes paid before submitting Form CR-108 (Notice of Business Closure). Kansas does not appear to bar cancellation the way Nevada does, but the absence of a formal trailing nexus rule creates ambiguity — KDOR should be contacted directly to confirm eligibility.
