The concept of “nexus” is central to understanding sales tax liability for businesses. In this comprehensive article, we’ll delve into the concept of nexus in sales tax, explain how it determines tax liability, and explore Yonda Tax’s guidance on monitoring and managing nexus.

The Significance of Nexus

In the world of sales tax, nexus is a critical term. It represents the connection or presence that a business has in a particular state, and it is the primary factor that determines whether a business is liable for collecting and remitting sales tax in that state.

Physical Nexus

In the past, nexus was primarily determined by a physical presence in a state. This included having a brick-and-mortar store, warehouse, employees, or other physical assets in a state. Physical nexus was relatively straightforward to understand.

Economic Nexus

However, with the advent of e-commerce and the significant growth of online sales, the concept of nexus has evolved. Today, many states have adopted the concept of economic nexus. Economic nexus means that a business can have a tax obligation in a state based on its level of economic activity, such as sales revenue or the number of transactions, even without a physical presence.

Understanding Economic Nexus Thresholds

Each state can set its own economic nexus thresholds. These thresholds vary from state to state and can include criteria such as:

  • Dollar Sales Threshold: If a business’s sales in a state exceed a certain dollar amount, it triggers economic nexus.
  • Transaction Threshold: If a business conducts a certain number of transactions in a state, it can create economic nexus.

Understanding these thresholds is crucial for businesses to determine when they have triggered a tax obligation in a specific state.

The Role of Nexus in Sales Tax Compliance

Nexus plays a fundamental role in sales tax compliance. It determines where a business is required to register for sales tax permits, collect tax from customers, and remit it to the appropriate taxing authorities.

Monitoring and Managing Nexus

To ensure compliance, businesses must monitor and manage their nexus in different states. This involves:

  • Regularly Reviewing Nexus: Keep track of your sales and transactions in each state to understand when you have crossed economic nexus thresholds.
  • Registering for Permits: When you establish nexus in a state, you need to register for sales tax permits. This allows you to legally collect and remit sales tax.
  • Collecting and Remitting Sales Tax: Once registered, you are responsible for collecting sales tax from customers and remitting it to the state.
  • Staying Informed: Keep up-to-date with changes in tax laws and economic nexus thresholds to ensure ongoing compliance.


Nexus is the key to understanding sales tax liability for businesses. Whether it’s physical nexus or economic nexus, knowing when and where you have a tax obligation is crucial for compliance. Monitoring and managing nexus in different states is essential to ensure you meet your tax obligations and avoid penalties.
