Nexus Audits

Sales Tax Nexus Study

Do you know which states you have sales tax obligations in?

Our sales tax nexus (sales tax obligation) analysis is an in-depth assessment of your business activities. We work with you to gain both a macro and micro understanding of your business operations within various states. We then consider numerous factors to determine where you currently have nexus or may have nexus in the future.

What Our Sales Tax Nexus Study Determines

  Physical nexus

  Economic nexus

  Click-Through nexus

  Affiliate nexus

  Sales tax registration requirements

  Additional applicable taxes

Why Should You Consider More than Just Physical Nexus?

The Supreme Court’s decision in South Dakota v. Wayfair, Inc. allows states to mandate that businesses collect and remit sales taxes for transactions in that state—even if they don’t have a physical presence there.



This has major implications for eCommerce businesses. As a result of the court case, the majority of states have passed various economic, click-through, and affiliate nexus laws. To maintain tax compliance, your business must move beyond basic physical nexus reviews.

Save money, avoid fines, and stay in compliance.

How Is EAH’s Nexus Study Different?

EAH goes beyond physical nexus audits to understand your business’s true tax obligations with regard to economic, click-through, and affiliate nexus laws. These additional types of nexus are common for eCommerce businesses.

Our focus on the eCommerce industry, allows us to understand drop shipping, Amazon FBA, other 3rd party fulfillment services and marketplace facilitator sales. General sales tax service providers do not always understand the complexity of these unique eCommerce fulfillment methods.
