Spanish VAT invoices must be issued at the time of the taxable supply for non-taxable persons. For taxable customers, they may be issued by the 16th of the month following the supply. Invoices must be stored for four years. As with all EU states, Spain permits the use of electronic invoices under certain conditions.
