Why is BigCommerce Applying a Fallback Tax Rate of 10 percent?


What is this "Fallback Tax rate" of 10%, that I keep seeing on my invoice lines as a Tax Override?




  • The Fallback tax rate is generated by BigCommerce and is the result of an error during tax calculation using AvaTax. 
    • From the BigCommerce Support for AvaTax website:  A fallback tax rate of 10% happens when there is a failure to connect to the automatic tax calculation service, if there is no shipping origin address set up in the Shipping Manager or the address could not be validated. Check the Shipping Setup and ensure there is a valid address set as a Shipping Origin. Check to see if there are any service performance issues with Avalara's service
