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.

Does Ohio have a sales tax?

Yes. The statewide base rate is 5.75%. Remote sellers collect it once they have nexus.

When do I have to register for sales tax in Ohio?

Can I cancel my Ohio registration if I'm under the threshold?

Generally yes, after clearing Ohio's trailing-nexus window and filing a final return.

Do you need to collect sales tax in Ohio?

You have a duty to collect once you have nexus: physical presence (inventory, staff, an office) or economic nexus from crossing $100,000 in sales or 200 transactions over current or previous calendar year. Ohio still counts transactions: crossing 200 transactions creates nexus even on modest revenue.

The Ohio rate

Ohio's statewide base rate is 5.75%. County and transit authority taxes add 0.50%–2.25%, creating combined rates ranging from approximately 6.50% to 8.75% depending on county.

Marketplace and direct sales

Marketplaces like Amazon collect Ohio tax for you, but those sales still count toward your threshold. Direct sales on your own store you collect yourself.

Filing and zero returns

Once registered, Ohio requires a return every assigned period even when you owe $0 — miss one and you can face penalties. Ohio assigns filing frequency based on tax liability: semi-annual (liability under $1,200 per 6-month period); quarterly (liability under $15,000 per quarter); monthly (liability exceeding $1,200 per 6-month period or annual liability above $75,000).

When you can cancel

If your Ohio returns are mostly $0, you may be over-registered. Canceling your Ohio sales tax registration makes sense once you have dropped below the $100,000 / 200-transaction threshold for a full preceding calendar year, ensuring your economic nexus obligation has truly lapsed — because Ohio's measurement period means crossing the threshold in any year keeps you obligated through the following year. The catch is Ohio's 12-month re-entry rule: if you resume any nexus-creating Ohio activities within 12 months of cancellation, the state will presume you never actually ceased nexus, potentially requiring back tax and penalties.

Where TrailingZero fits

TrailingZero connects to your store read-only, maps where you actually have nexus state by state, and maps your real nexus in Ohio and flags whether you should register, keep filing, or cancel. 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.
