A Boolean property on Commerce Cloud order objects, TaxCalculated, indicates how tax was calculated for the order:
If the value of
TaxCalculatedistrue, tax was calculated normally by your specified tax processor.If the value of
TaxCalculatedisfalse, the default tax rate you set was applied to the order.
This property is also included in the data Commerce Cloud sends in the Order Submit webhook. You can use this information to identify orders to which the default tax rate was applied so you can decide how to handle them in your order management system.
