No matter the size of a company or the breadth of its products and services, they all need tax software that can bridge disparate and siloed data to manage the tax compliance process end to end. Having reliable APIs is the first step in achieving this goal.

We offer a nexus tool to help you determine where you have a nexus obligation. Depending on the number of states you have customers in, tracking software may be a worthy investment. For instance, AvaTax tracks sales in real time, alerting you when you reach 80 percent of nexus thresholds and when you need to register in a new state.

Physical nexus is established by the presence of your business in a state. In addition to a store or office, physical nexus may be triggered by off-site employees, warehouse locations, affiliations, even trade shows attendance. 2. Economic nexus is determined based on where your customers are located. If you reach a certain sales volume or number of transactions with residents of a jurisdiction, you can trigger nexus. 3. It’s important to note that you’ll need to register and remit sales tax if you have either physical nexus or economic nexus.
