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 Maryland have a sales tax?

Yes. The statewide base rate is 6%. Remote sellers collect it once they have nexus.

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

When you have physical presence there or cross $100,000 in sales or 200 transactions over previous or current calendar year.

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

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

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.

Do you need to collect sales tax in Maryland?

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 previous or current calendar year. Maryland still counts transactions: crossing 200 transactions creates nexus even on modest revenue.

The Maryland rate

Maryland has a single statewide sales and use tax rate of 6%. There are no local or county sales tax rates — the rate is uniform across the entire state.

Marketplace and direct sales

Marketplaces like Amazon collect Maryland 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, Maryland requires a return every assigned period even when you owe $0 — miss one and you can face penalties. Filing frequency is assigned by the Comptroller based on average monthly tax liability.

When you can cancel

If your Maryland returns are mostly $0, you may be over-registered. Canceling your Maryland sales tax registration makes sense if your sales into Maryland have fallen below $100,000 in gross revenue AND below 200 separate transactions for both the prior and current calendar year, since Maryland has no defined trailing nexus period and the Comptroller has confirmed you may discontinue collection once both thresholds are unmet. The catch is that you must file a final return alongside Form SUT202FR and retain records proving you no longer meet either threshold — if the Comptroller later disputes your exit, you need documentation.
