Customs Duty not transmitting to Shopify for Ontario orders An issue in Avalara for Shopify caused Customs Duty that was correctly calculated in AvaTax for orders shipping to Ontario to fail to transmit back to Shopify. As a result, Customs Duty did not appear on affected Shopify orders. Now, Customs Duty calculated by AvaTax for Ontario transactions is transmitted and reflected in Shopify. This ensures consistency between AvaTax and Shopify order details. Transaction error during Tax Override An issue with low value document-level tax overrides caused the following error Tax override cannot be applied. No taxable details found to apply tax. The issue occurred when the rounding step rounded all distributed non-fee tax amounts to 0.00. It prevented the remaining tax override amount from being distributed successfully. AvaTax now distributes the tax override using unrounded tax amounts in this case, to ensure that transactions complete successfully.
