A Member State shall identify independently the taxable persons which it intends to propose for a simultaneous control. The competent authority of that Member State shall notify the competent authority of the other Member States concerned of the cases proposed for a simultaneous control. It shall give reasons for its choice, as far as possible, by providing the information which led to its decision. It shall specify the period of time during which such controls should be conducted.

The competent authority of the Member State that receives the proposal for a simultaneous control shall confirm its agreement or communicate its reasoned refusal to its counterpart authority, in principle within two weeks of receipt of the proposal, but within a month at the latest.

Each competent authority of the Member States concerned shall appoint a representative to be responsible for supervising and coordinating the control operation.
