Setup TaxJar automation

TaxJar automates tax calculation and provides reporting and filing functions. It takes minutes to set up. For more information go to

The TaxJar solution consists of two elements:

  • Creating a TaxJar account.
  • Using the TaxJar plugin.


Sales Tax collection is based upon a connection between your business and a tax jurisdiction. This connection is a Nexus.

From a tax perspective, if your business has a presence in one or a number of States, the Tax Authority may be allowed by law, to enforce you to collect or pay Tax. 

For more detail refer to Sales Tax Nexus Defined.
