Built for e-commerce sellers, resellers, and small businesses.
Run automatically.

Alex and Euwye came up through accounting doing exactly this work — multi-state sales tax filings, nexus analysis, back-period catch-ups, voluntary disclosure negotiations. Between them, they've filed across all 46 U.S. sales tax jurisdictions, talked sellers through audits, and watched the same pattern repeat: someone builds a real business on eBay or Shopify, crosses the threshold in six states without realizing it, and then gets a letter from one of them. Then the panic.

The software that existed was built for enterprise compliance teams with dedicated tax staff. Opaque pricing, mandatory sales calls, minimum annual contracts, and interfaces that assumed a CPA was already on staff to interpret the output. The sellers who needed help most — individual resellers, multi-platform sellers, small DTC brands — weren't the customer those products were designed for.

So we built the product we would have recommended to those sellers, priced the way it should have always been priced: $19.99 per return, no monthly fee, free nexus monitoring forever.

How Taxero actually works

Taxero is not an API wrapper or an automated rule engine that fires and hopes for the best. Every return goes through a process that combines AI-assisted preparation with human review before it's filed. The software calculates your nexus exposure, maps your sales to the correct jurisdictions, applies the right rates, and prepares the return. A human reviews it. Then it goes out.

That's a meaningful distinction. Fully automated systems make mistakes that don't surface until you get a notice — wrong rate applied, incorrect entity type, wrong filing period. Having people who have actually filed in all 46 U.S. sales tax jurisdictions look at returns before they go out catches those mistakes. It also means you have a real person to call if something comes up.

The nexus monitoring side is fully automated. We watch your sales in real time, alert you when you're approaching a threshold, and handle registration automatically when you cross one. You don't have to know that Kansas has no transaction threshold, or that New York requires both thresholds to be met, or that Alabama has a simplified 8% flat rate program that most sellers should use. We know, and we apply it.
