1. The following shall be determined in accordance with the procedure provided for in Article 58(2):

(a) the exact categories of information subject to automatic exchange;

(b) the frequency of the automatic exchange for each category of information; and

(c) the practical arrangements for the automatic exchange of information.

A Member State may abstain from taking part in the automatic exchange of information with respect to one or more categories where the collection of information for such exchange would require the imposition of new obligations on persons liable for VAT or would impose a disproportionate administrative burden on the Member State.

The results of the automatic exchange of information for each category shall be reviewed once a year by the Committee referred to in Article 58(1), so as to ensure that this type of exchange takes places only where it is the most efficient means for the exchange of information.
