Commerce v1 Modules Taxes TaxJar

Added in Commerce 0.3, the TaxJar module provides an integration with the TaxJar SmartCalcs API for fully automated and highly accurate US Sales Tax calculations.

TaxJar requires a subscription starting at $19 USD per month. In return, you don't have to worry about figuring out appropriate destination and sender based sales tax rates.


  • TaxJar API Token: this is provided by TaxJar under Account > SmartCalcs API.
  • Nexus State: the state from where you sell or ship your products.
  • Nexus Zip: the zipcode from where you sell or ship your products.

If you have more than one Nexus, you can add those to your TaxJar account and they'll be taken into consideration as well.
