Economic Nexus: The Key To Understanding Sales Tax Obligations In The Digital Era

Updated: Jan 23

Economic nexus refers to the connection between a business and a state that triggers a tax obligation based on economic activity within that state, rather than a physical presence. Traditionally, businesses were only required to collect and remit sales tax if they had a physical presence, such as a brick-and-mortar store or warehouse, in a particular state. However, the rapid growth of online commerce prompted states to reconsider their approach.


1. Defining Economic Nexus:

Traditionally, businesses were only required to collect and remit sales tax in states where they had a physical presence, such as a brick-and-mortar store, warehouse, or office. Economic nexus expands the scope of tax obligations by considering the economic activities of a business in a state, regardless of physical presence. In other words, if a business meets certain economic thresholds in a state, it establishes economic nexus and is required to comply with that state's sales tax laws.

2. Determining Economic Nexus Thresholds:

Economic nexus thresholds vary by state and may include factors such as the total sales revenue, the number of transactions, or a combination of both. For example, a state might set a threshold of $100,000 in sales or 200 transactions within a calendar year. If a business exceeds these thresholds in a particular state, it triggers economic nexus, necessitating the collection and remittance of sales tax.

3. Impact on Businesses in the Digital Era:

In the digital era, businesses engage in online sales, cross-border transactions, and e-commerce platforms, making it challenging to determine their tax obligations. Economic nexus is particularly relevant for businesses conducting transactions across state lines, as the traditional physical presence requirement may no longer be the sole determinant of tax liability.

4. E-commerce and Economic Nexus:

E-commerce businesses, in particular, need to be vigilant about economic nexus rules. Selling products or services online can quickly lead to meeting economic thresholds in multiple states. Understanding where customers are located, tracking sales data, and 5 5. Informed and Adapting Strategies:

Economic nexus rules are subject to change, and staying informed about updates in state tax laws is crucial. Businesses must regularly review economic nexus thresholds and other relevant regulations to adapt their strategies and remain compliant.


Economic nexus laws consider factors like the volume of sales, the number of transactions, or the total revenue generated within a state's borders. This means that businesses engaging in significant economic activity, even without a physical presence, may be subject to sales tax obligations in certain jurisdictions. Having employees in another state may create a sufficient economic connection to trigger economic nexus in that state. The presence of employees can contribute to the economic activity of the business within the state, and some states consider this factor when determining economic nexus.
