Connects WooCommerce to the TaxJar service. It can calculate sales tax at cart and checkout through the TaxJar API, sync orders, refunds and cancellations for return reporting, and manage customer exemptions and product tax codes. Suits US stores that already use or will use a TaxJar account. Limit: it does nothing useful without a TaxJar account and API token, and calculation depends on that external service.

Pros

  • Calculates sales tax at cart and checkout through the TaxJar API
  • Syncs orders, refunds and cancellations to TaxJar for return reporting
  • Supports customer tax exemptions, product tax codes and nexus regions

Cons

  • Requires a TaxJar account and API token; calculation depends on that service
  • Readme says stores above 1,000 orders a month need an upgraded TaxJar account
  • Cart and order totals call the external API while tax calculation is enabled
