Article 3 Thirteenth Directive 86/560/EEC

1.The refunds referred to in Article 2 (1) shall be granted upon application by the taxable person. Member States shall determine the arrangements for submitting applications, including the time limits for doing so, the period which applications should cover, the authority competent to receive them and the minimum amounts in respect of which applications may be submitted. They shall also determine the arrangements for making refunds, including the time limits for doing so. They shall impose on the applicant such obligations as are necessary to determine whether the application is justified and to prevent fraud, in particular the obligation to provide proof that he is engaged in an economic activity in accordance with Article 4 (1) of Directive 77/388/EEC. The applicant must certify, in a written declaration, that, during the period prescribed, he has not carried out any transaction which does not fulfil the conditions laid down in point 1 of Article 1 of this Directive.

2.Refunds may not be granted under conditions more favourable than those applied to Community taxable persons.
