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.

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.

Florida trailing nexus

Florida has trailing nexus of roughly 12 months. Florida's economic nexus uses a previous-calendar-year measurement period: if a seller exceeded $100,000 in taxable Florida sales during Year N, nexus (and collection obligations) persist throughout all of Year N+1 regardless of Year N+1 sales volume.

What trailing nexus means

When you drop below Florida's threshold, the obligation doesn't end instantly. Most states make you keep the registration active and keep filing — even $0 returns — for a defined window. That window is "trailing" (or "sticky") nexus.

Florida's trailing-nexus rule

Florida's economic nexus uses a previous-calendar-year measurement period: if a seller exceeded $100,000 in taxable Florida sales during Year N, nexus (and collection obligations) persist throughout all of Year N+1 regardless of Year N+1 sales volume. If sales in Year N+1 also fall below $100,000, nexus does not extend into Year N+2. Florida has no separately published 'trailing nexus' policy beyond this annual reset mechanism — no additional look-back period beyond the built-in one-year lag.

Seller must file a final return within 15 days of closing/inactivating the account. Florida treats accounts closed for more than approximately one year as new registrations if the business later re-registers, so prior filing history may be lost.

Why it matters for canceling

Canceling the day you drop below the threshold — or skipping a required final return — is exactly what triggers penalties. Clear Florida's window first, file every return due during it, then close the account.

Where TrailingZero fits

TrailingZero connects to your store read-only, maps where you actually have nexus state by state, and computes Florida's exact trailing-nexus end date so you cancel on the right day, not too early. 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.
