About TrailingZero
Stop paying to file sales tax in states you don't owe.
Note: we're finalizing our company and team details ahead of launch — some information on this page is being completed.
Why we exist
After the 2018 South Dakota v. Wayfair decision, most online sellers registered for sales tax in a dozen or more states — often because of a 200-transaction trigger that caught even tiny revenue. Since 2023, sixteen-plus states have deleted that trigger. Many sellers are now over-registered, filing zero-dollar returns in states they no longer owe anything to. TrailingZero exists to find those registrations you can safely cancel — and to do it in the right order so you never trip a penalty.
The team
Our guides are written and maintained by a named editor and reviewed for accuracy by a licensed tax professional before publication. Tax rules are high-stakes, so every state page carries a byline and a last-reviewed date.

How we make money
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.
How we research the rules
Every figure on a state page is built from the state's Department of Revenue and reputable tax-research sources, carries a confidence level, and is flagged for manual review where sources disagree. Read the full method, our review cadence, and how to report a correction in our editorial & accuracy policy.
