What is nexus?

Nexus is the legal trigger that makes you responsible for collecting and paying sales tax in a state. If you sell enough into a state, you owe tax there.

Most states use economic nexus thresholds — typically $100,000 in sales or 200 transactions in a 12-month period. Cross that threshold and you need to register and file.

The problem:

If you sell to customers across 15 states, you have 15 different thresholds to track — each with different rules and deadlines. That's exactly what Taxero handles automatically.

What Taxero does NOT do (yet)

We believe in honesty about scope. Phase 1:

  • Handle audit defense services (we store all your filings so you always have evidence)
  • Provide audit defense services (we store all your filings so you always have evidence)
  • Replace your accountant for complex tax questions outside sales tax
  • File for states where you have not yet crossed nexus (we monitor until you do)
