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.
