The Portuguese Tax Authority (AT) launched on Friday a campaign to regulate Value Added Tax (VAT) invoicing, nationwide.

The campaign aims to verify, through door-to-door inspection, compliance with Article 27 of the VAT Code (relating to the obligation to issue invoices or equivalent documents for each transmission of goods or provision of services) and to alert economic agents to the need for invoicing as an essential basis for the regularization of VAT obligations, explains a statement from the AT.

VAT compliance, in turn, influences the payment of other direct taxes, such as corporate income tax (IRPC).

VAT provides a significant proportion of revenue collection, both domestically and in foreign trade taxes.
