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.

Idaho base rate

Idaho's statewide base sales tax rate is 6%, before local/district taxes that push the combined rate higher in many areas.

The Idaho sales tax rate

Idaho's statewide base rate is 6%. Resort communities may impose a local option sales tax of up to 3% (e.g., Sun Valley area), bringing combined rates as high as 9%. There is no general local sales tax beyond these resort-community special districts.

What rate do online sellers charge?

Idaho uses destination-style rates in most cases, so the rate you charge depends on where your buyer is — the state base of 6% plus any local/district tax at the delivery address.

You only charge Idaho tax once you have nexus there — physical presence or crossing $100,000 in sales.

Who collects it

On marketplace sales (Amazon, Etsy, eBay), the marketplace facilitator collects and remits Idaho tax for you. On your own store (Shopify, WooCommerce) you collect it yourself once you're registered.

Where TrailingZero fits

TrailingZero connects to your store read-only, maps where you actually have nexus state by state, and makes sure you're only registered to charge Idaho tax where you actually have to be.
