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 Kentucky sales tax registration makes sense if you have permanently dropped below the $100,000 economic nexus threshold and have no physical presence in the state (including no FBA inventory in Kentucky fulfillment centers), since continuing to hold a permit requires filing zero returns every period or facing penalties. The main catch is that Kentucky measures nexus on a calendar-year basis, so if you exceeded the threshold in a prior year you remain obligated through the current year — you should not cancel mid-year if your prior-year sales exceeded $100,000.

Do you still have nexus in Kentucky?

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 Kentucky creates it. Physical nexus triggers include: owned or leased property used in Kentucky, employees or independent contractors in the state, inventory stored in any warehouse or third-party fulfillment center (including Amazon FBA), services performed in-state, computer software used by Kentucky third parties, and trade show participation of 15 or more days annually. 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 Kentucky

Kentucky uses a calendar-year measurement period. If economic nexus thresholds were exceeded in a given calendar year, the seller maintains nexus obligations through the entirety of the following calendar year (i.e., 'previous or current calendar year' lookback). Once the seller no longer meets the threshold in either the preceding or current calendar year, they may seek to cancel registration. No explicit statutory trailing nexus period beyond this calendar-year carryover has been published by the Kentucky Department of Revenue.

A final sales tax return must be filed before the cancellation is complete. Sellers should not cease tax collection until the account is formally closed and confirmed by the Department. Businesses that previously registered solely due to the 200-transaction threshold (now removed as of August 1, 2026) may have grounds to deregister if the $100,000 sales threshold is also not met.
