The regulations will make e-invoicing in B2B transactions (i.e., commercial transactions between entrepreneurs and self-employed individuals in Spain) mandatory, subject to exceptions for transactions involving persons that are not based in or established in Spain. They also will provide for the creation of a network of private platforms or a public system to be used for the submission of e-invoices; taxpayers will be able to elect to use a private or the public platform (the latter will probably be more appropriate for small businesses). The Spanish tax authorities will have to set up the public system to receive e-invoices in a standardised format where invoices can be validated and then made available to recipients.
