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 Alabama have a sales tax?

Yes. The statewide base rate is 4%. Remote sellers collect it once they have nexus.

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

When you have physical presence there or cross $250,000 in sales over previous calendar year.

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

Generally yes, after clearing Alabama'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.

Estimate only — general education, not tax advice. Confirm with Alabama's tax authority before you register or deregister.

Do you need to collect sales tax in Alabama?

You have a duty to collect once you have nexus: physical presence (inventory, staff, an office) or economic nexus from crossing $250,000 in sales over previous calendar year. Alabama has never used a transaction-count trigger — only the sales figure matters.

The Alabama rate

The general Alabama state sales tax rate is 4%. Reduced rates apply to specific categories: automobiles (2%), farm equipment (1.5%), food/grocery (2%, with a temporary suspension May 1-June 30, 2026), manufacturing machinery (1.5%).

Marketplace and direct sales

Marketplaces like Amazon collect Alabama tax for you, but those sales don't count toward your own threshold. Direct sales on your own store you collect yourself.

Filing and zero returns

Once registered, Alabama requires a return every assigned period even when you owe $0 — miss one and you can face penalties. Monthly if average monthly liability is $200 or more in the preceding calendar year; quarterly if average monthly liability is less than $200; annual if total liability is less than $200 for the full preceding calendar year.

When you can cancel

If your Alabama returns are mostly $0, you may be over-registered. Canceling your Alabama sales tax registration makes sense once you have completed a full calendar year below the $250,000 threshold and your obligation for the trailing lookback year has ended. The process is online via My Alabama Taxes — you submit a closure request through 'Other Actions' and must file all outstanding returns and specify an effective closure date.

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 Alabama 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.
