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.

Do I need to collect sales tax in Maine?

Only once you have nexus: physical presence, or crossing $100,000 in sales over previous or current calendar year. Under that, with no physical presence, you generally don't.

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.

Should I register for sales tax in Maine?

Before you register for sales tax in Maine, check whether you actually have to. Registering when you don't owe just adds a recurring return — here's exactly when Maine requires it.

When you must register

You must register in Maine if you have physical presence there (inventory, staff, an office) or you cross $100,000 in sales (previous or current calendar year). Below that, with no physical presence, you generally don't have to.

When registration is required in Maine

Maine requires registration once you cross $100,000 in sales, measured over previous or current calendar year. Maine used to trigger nexus at 200 transactions but removed that count in January 2022 — only the sales figure matters now.

Physical presence registers you regardless of sales. Standard physical nexus triggers apply: offices, employees, agents, or representatives in Maine.

The marketplace nuance most sellers miss

If you sell only through a marketplace like Amazon or Etsy, the marketplace facilitator generally collects and remits Maine tax for you, so you may not need your own permit. In Maine, facilitated sales do not count toward your own threshold.

How to register in Maine

Don't over-register

Most over-registered sellers signed up defensively across many states after 2018. If you're under Maine's threshold with no physical presence, registering early just creates a recurring zero-dollar return. Register when you truly must — and track the states where you can stop.

Where TrailingZero fits

TrailingZero connects to your store read-only, maps where you actually have nexus state by state, and flags when you genuinely cross Maine's threshold — and where you've already dropped below and can deregister. 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.
