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 Alabama sales tax registration makes sense once you have completed a full calendar year below the $250,000 threshold and your obligation for the trailing lookback year has ended. The process is online via My Alabama Taxes — you submit a closure request through 'Other Actions' and must file all outstanding returns and specify an effective closure date.

Do you still have nexus in Alabama?

You can only cancel once your obligation has ended. Two things create it: physical presence (inventory, an employee, an office) and economic nexus (crossing $250,000 in sales).

For Amazon FBA and 3PL sellers the sneaky one is physical nexus: storing inventory in Alabama creates it. Standard physical nexus triggers apply: employees, offices, warehouses, agents, or inventory stored in Alabama (including Amazon FBA fulfillment centers) create immediate nexus regardless of sales volume. 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 Alabama

Alabama has not published a formal trailing nexus policy. However, because the threshold is evaluated on the previous calendar year basis, a seller who exceeded $250,000 in Year 1 must collect throughout Year 2; if sales in Year 2 are below $250,000, the obligation ends December 31 of Year 2. This creates a natural one-year trailing obligation built into the lookback structure rather than an explicitly codified trailing nexus rule.

All delinquent returns must be filed before account closure. Accounts cannot be backdated beyond the current billing period. Alabama courts had not addressed trailing nexus as of the last reported decision (2013 acknowledgment). No explicit statutory trailing nexus period beyond the lookback mechanism.
