Sales Tax Economic Nexus: What You Need to Know

Updated: Nov 15

In the ever-evolving landscape of taxation, sales tax economic nexus has become a critical concept for businesses and tax authorities alike. With the rise of e-commerce and the expansion of businesses across state lines, understanding and complying with economic nexus rules is essential to avoid potential tax liabilities and penalties. In this article, we will explore what sales tax economic nexus is, how it impacts businesses, and steps you can take to ensure compliance.

Sales tax economic nexus refers to the connection a business has with a particular state that obligates them to collect and remit sales tax on sales made within that state, even if the business lacks a physical presence there. Traditionally, businesses were only required to collect sales tax in states where they had a physical presence, such as a brick-and-mortar store or warehouse. However, the growth of e-commerce has prompted states to adopt new tax laws that expand their tax reach beyond physical presence.

Key Factors Determining Economic Nexus

States have their own criteria for establishing economic nexus, but there are some common factors that typically trigger this obligation:

Many states have set specific sales thresholds, often based on either a total sales revenue amount or the number of transactions conducted within the state. Once a business surpasses these thresholds, they are considered to have economic nexus in that state.

Transaction Thresholds

Some states focus on the number of individual transactions rather than total revenue. If a business exceeds a certain number of transactions within a state, it may trigger economic nexus.

Gross Sales Amount

In some states, the economic nexus can be triggered if a business's gross sales revenue from in-state customers reaches a particular threshold, regardless of the number of transactions.

Click-Through Nexus

A few states have enacted click-through nexus laws, which apply when a business has agreements with in-state affiliates or partners that generate sales through referrals or links. If a business has a substantial affiliate presence in a state, it can trigger economic nexus.

Understanding and complying with sales tax economic nexus is crucial for several reasons:

Legal Compliance

Failing to comply with economic nexus rules can result in legal consequences, including penalties and interest charges.

Customer Expectations

Consumers expect transparent pricing, and non-compliance can lead to customer dissatisfaction or loss of business.

Competitive Advantage

Compliance can provide a competitive advantage by demonstrating a commitment to transparency and trustworthiness.

Tax Planning

Understanding your economic nexus footprint can help you plan your business operations and tax strategies more effectively.

Compliance with Economic Nexus

To ensure compliance with sales tax economic nexus, businesses should consider the following steps:

Identify Your Nexus

Determine which states you have triggered economic nexus in based on the specific criteria of each state.

Register for Sales Tax

Once nexus is established, register for sales tax permits in the applicable states.

Sales Tax Collection

Begin collecting sales tax from customers in those states and keep accurate records of your transactions.

File regular sales tax returns in each state where you have economic nexus and remit the collected taxes.

Stay Informed

Monitor changes in state tax laws and regulations, as they can evolve over time, potentially affecting your nexus status.


Sales tax economic nexus is a critical concept that has evolved to address the challenges posed by e-commerce and the modern business landscape. Businesses must be proactive in identifying and complying with economic nexus requirements to avoid legal consequences and maintain their competitive edge.
