For the purposes of this Directive, the taxable person may decide the place of storage of all invoices provided that he makes the invoices or information stored in accordance with Article 244 available to the competent authorities without undue delay whenever they so request.

Member States may require taxable persons established in their territory to notify them of the place of storage, if it is outside their territory.

Member States may also require taxable persons established in their territory to store within that territory invoices issued by themselves or by their customers or, in their name and on their behalf, by a third party, as well as all the invoices that they have received, when the storage is not by electronic means guaranteeing full on-line access to the data concerned.

Each Member State shall determine the period throughout which taxable persons must ensure the storage of invoices relating to the supply of goods or services in its territory and invoices received by taxable persons established in its territory.

In order to ensure that the requirements laid down in Article 233 are met, the Member State referred to in paragraph 1 may require that invoices be stored in the original form in which they were sent or made available, whether paper or electronic. Additionally, in the case of invoices stored by electronic means, the Member State may require that the data guaranteeing the authenticity of the origin of the invoices and the integrity of their content, as provided for in Article 233, also be stored by electronic means.

The Member State referred to in paragraph 1 may lay down specific conditions prohibiting or restricting the storage of invoices in a country with which no legal instrument exists relating to mutual assistance similar in scope to that provided for in Directive 2010/24/EU and Regulation (EC) No 1798/2003 or to the right referred to in Article 249 to access by electronic means, to download and to use.
