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.

What is economic nexus in Oklahoma?

Economic nexus means you can owe sales tax in Oklahoma based purely on your sales volume there — no physical presence required. It traces to the 2018 South Dakota v. Wayfair decision. Oklahoma's threshold took effect November 2019.

Today the threshold is $100,000 in sales, measured over previous or current calendar year.

The transaction-count history

Oklahoma has never used a transaction-count trigger — only the sales figure matters.

If your only nexus reason is the transaction count, watch it closely — a low-revenue, high-order business can cross it.

What counts toward the threshold

aggregate sales of tangible personal property; marketplace sales excluded when marketplace facilitator is collecting Oklahoma tax on seller's behalf

Marketplace-facilitated sales do not count toward your own Oklahoma threshold.

Where TrailingZero fits

TrailingZero connects to your store read-only, maps where you actually have nexus state by state, and tracks your sales against Oklahoma's threshold so you register only when you truly cross it — and deregister when you fall below. 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.
