Different jurisdictions impose varying sales taxes, often overlapping as states, counties, and municipalities each enforce their own. Sales taxes are intricately linked to use taxes, affecting residents who make purchases outside their jurisdiction. While both are generally set at the same rate, use taxes are challenging to enforce and typically apply to substantial tangible goods acquisitions. Consider a scenario where a Georgia resident buys a car in Florida; she must pay the local sales tax as if the purchase were made at home.The concept of "nexus" plays a pivotal role in determining whether a company owes sales taxes to a specific government. While traditionally tied to a physical presence, nexus extends beyond offices or warehouses, encompassing employees in a state or affiliate relationships. This dynamic relationship between e-commerce and sales taxes is exemplified by New York's "Amazon laws," compelling online retailers like Amazon.com Inc. to pay sales taxes, even without a physical presence in the state. The evolving landscape of taxation in a digital era underscores the complexities businesses face in navigating these jurisdictional challenges.
