70Article 4(1) of Directive 2008/55 provides that ‘[a]t the request of the applicant authority, the requested authority shall provide any information which would be useful to the applicant authority in the recovery of its claim’. That directive thus enables the Member State of origin to obtain information from the competent authority of the host Member State on the transfer of the residence of an individual to that Member State, in so far as the information is necessary to enable the Member State of origin to recover a tax debt which existed already at the time of that transfer.
