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 Mississippi sales tax permit makes sense once your trailing 12-month gross sales into the state have fallen and stayed below $250,000, since Mississippi evaluates nexus on a rolling basis with no codified trailing-nexus extension. The main catch is that you must file a final sales tax return before closing the account, and you should ensure all zero returns for prior periods are filed and any outstanding tax is paid — failing to do so can expose you to penalties and prevent clean closure.

Do you still have nexus in Mississippi?

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 Mississippi creates it. Standard physical nexus triggers: offices, storefronts, warehouses, employees, agents, and independent representatives performing sales or support functions in Mississippi. 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 Mississippi

Mississippi has no formal trailing nexus statute or published administrative policy establishing a defined hold period after sales drop below $250,000. Because the state evaluates nexus on a rolling 12-month basis, economic nexus obligations lapse once the trailing 12-month gross sales fall below the $250,000 threshold. There is no codified additional calendar-year tail or lookback extension.

No statutory trailing period identified. Seller must file a final return before canceling the permit. Because Mississippi lacks a published trailing-nexus rule, DOR could take a conservative enforcement position; consulting the DOR directly is advisable before canceling.
