Nexus tracking, before the state knows.
Sales tax nexus is triggered the moment you cross a state's economic threshold. Taxero monitors every dollar across all 50 states so you know before you owe.

Nexus is the legal connection between your business and a state that requires you to collect and remit sales tax there.
Since the 2018 South Dakota v. Wayfair Supreme Court decision, every state can impose economic nexus: meaning if you sell enough goods to customers in a state, you owe sales tax there. No physical presence required.
Most states use a $100,000 revenue or 200 transaction threshold. Some, like California, Texas, and New York, have higher thresholds. Miss one, and you could face back taxes, penalties, and interest.
How Taxero tracks your nexus
Three steps. Fully automated. Nothing falls through the cracks.
Upload your sales
Import CSV exports from Shopify, Amazon, eBay, Etsy, or any platform. We normalize everything automatically.
We calculate exposure
Taxero aggregates sales by state, calculates revenue and transaction counts, and maps them against each state's economic nexus thresholds.
Alert fires the moment you cross
When you hit 80% of a threshold, you get an early warning. When you cross it, you get an instant alert with exactly what's required.
