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.

Does Kentucky have a sales tax?

Yes. The statewide base rate is 6%. Remote sellers collect it once they have nexus.

When do I have to register for sales tax in Kentucky?

When you have physical presence there or cross $100,000 in sales over previous or current calendar year.

No. This page is general education built from public sources and the rules change often. Confirm your specific situation with the state's tax authority or your accountant before you register or deregister.

Do you need to collect sales tax in Kentucky?

You have a duty to collect once you have nexus: physical presence (inventory, staff, an office) or economic nexus from crossing $100,000 in sales over previous or current calendar year. Kentucky used to trigger nexus at 200 transactions but removed that count in August 2026 — only the sales figure matters now.

The Kentucky rate

Kentucky imposes a uniform 6% statewide sales and use tax. There are no city, county, or local sales taxes in Kentucky, making it one of the simpler states for rate calculation.

Marketplace and direct sales

Marketplaces like Amazon collect Kentucky tax for you, but those sales still count toward your threshold. Direct sales on your own store you collect yourself.

Filing and zero returns

Once registered, Kentucky requires a return every assigned period even when you owe $0 — miss one and you can face penalties. Filing frequency is assigned by the Kentucky Department of Revenue and programmatically adjusted each June based on annual sales tax liability.

When you can cancel

If your Kentucky returns are mostly $0, you may be over-registered. 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.

Where TrailingZero fits

TrailingZero connects to your store read-only, maps where you actually have nexus state by state, and maps your real nexus in Kentucky and flags whether you should register, keep filing, or cancel. During any wind-down it can file the zero-dollar returns so nothing lapses — and you only pay for the states you genuinely keep. Run a free audit anytime; this page is free education either way.
