Introduction to US Sales Tax and Economic Nexus

Stripe Free Intermediate

The clearest global explainer of economic nexus, the international equivalent of India's e-commerce mandate: the idea that selling through a platform or crossing a revenue line can force registration even without a local office.

• Economic nexus in most US states kicks in once a seller crosses a threshold, commonly $100,000 in sales or 200 transactions, with some states like California and Texas set higher at $500,000.
• Physical presence, a warehouse, a remote employee, even a trade show booth, can also trigger nexus regardless of revenue.
• Useful mental model for founders eyeing US sales alongside their India business.
