What is Economic Nexus? Economic nexus is a legal standard establishing a sales tax obligation for businesses based on their economic activity within a state, even without a physical presence [1]. This concept became highly relevant for ecommerce businesses after the 2018 Wayfair Supreme Court decision, which eliminated the physical presence requirement for sales tax collection [2]. Now, states define specific thresholds, typically based on a certain volume of sales revenue or number of transactions, that trigger an economic nexus obligation [3]. Understanding and managing economic nexus is crucial for online merchants to ensure sales tax compliance, avoid penalties, and prevent costly audits[2]. Neglecting these obligations can lead to significant financial risk and undermine business growth [1]. Staying compliant means continuously monitoring sales activity, registering in states where thresholds are met, and correctly collecting and remitting sales tax [3]. This legal framework means businesses must adapt their sales tax strategies to reflect their digital footprint. Below, you will find curated episodes detailing how to navigate the complexities of economic nexus.
