The trap
You registered to be safe. Then the rules moved.
After the 2018 Wayfair decision, most sellers signed up in a dozen or more states. Back then the trigger was 200 orders, even on tiny revenue. Since 2023, sixteen states deleted that 200-order rule. The thing that put you on the rolls is gone. The filing is not.

How it works
Three steps to a smaller filing bill.
- 01
Connect your store
Link Amazon, Shopify, or WooCommerce, read-only. We map where you actually have nexus, state by state.
- 02
See what you can cancel
We apply each state's trailing-nexus rules and show the exact date you can deregister, with the dollars you'll save.
- 03
We file until you're out
During the wind-down, zero-dollar returns get filed on time so you leave clean and never trip a penalty.
Why we exist
The tax tools make money every time you file.
Avalara, TaxJar and the rest charge per return. Telling you to close a permit means cutting their own invoice, so they don't. We make money by getting you off the rolls. Opposite incentive. That is the entire point.
The filing tools
- Priced per return
- Register everywhere, file forever
- Quiet about deregistration
TrailingZero
- Priced below the filings we cancel
- Cancel every state you safely can
- Tells you the exact date to stop
Up to 132%
TaxJar raised subscription prices for 2026 (per its published 2026 pricing). Filing in states you don't owe just got more expensive. Good time to file less.
Pricing
Priced below the filings we cancel.
You only pay for the states you keep — the savings cover it. Avalara and TaxJar charge per return; we charge to get you off the rolls.

Start free — no card required. Paid plans are billed monthly and you only pay for the states you keep. Filing fees in non-SST states are passed through at cost. Filing is free in the 24 Streamlined Sales Tax states as we roll out our Certified Service Provider path. TrailingZero is software, not a CPA or law firm.
TrailingZero is a commercial product: we earn subscription revenue and, at launch, a pass-through fee on filings. Unlike per-filing tax tools, our incentive is to help you file less — but it is still a commercial incentive, not impartial advice. Our guides are general education, reviewed for accuracy; they are not a substitute for your own CPA on your specific situation.
