Create a new AdditionalTaxIdentifier
Create a new AdditionalTaxIdentifier. An AdditionalTaxIdentifier is a seconday tax identifier that is used inside the EU when sending invoices to consumers. In that case, the VAT of the receiving country is used and if the sender has a local VAT identifier, that is used to identifiy the sender, instead of the sender's origin country VAT number. To use these identifiers, use the invoice.consumerTaxMode = true property.
