## **What is Economic Nexus?**

Since the landmark **South Dakota v. Wayfair** decision in 2018, states have expanded their sales tax laws to require remote sellers to collect and remit sales tax even without a physical presence. Instead, economic nexus laws establish tax obligations based on a seller’s total sales revenue or transaction volume within a state. you can find out nexus threshold details for every state by checking our [U.S. Sales and Use Tax Guide page](https://taxdo.com/resources/countries/us).
