    If you have already defined a product list in the last option of the payment wizard we have the taxes section.

    Enter the percentage for the calculation, you can also check the items to be exempted

    If you have an address field you can defined areas that will be exempted

    This option is applicable if you are using one of the payment widgets.

    If you are setting the total value using form calculator, you can add another form calculation field to calculate the tax value

    If you need further clarifications please feel free to contact us
