TaxJar, which is available in the WooCommerce extension store or the WordPress plugin directory, assists in computing the sales tax that must be collected at checkout.

Here is a rundown of the benefits of TaxJar:

  • Eliminates the hassle of manually uploading new tax rates.
  • Daily collection of tax rates and organization to help you be ready when tax deadlines are near.
