A person may provide the Commissioners for Her Majesty's Revenue and Customs with particulars of a transaction or transactions effected or to be effected by the person in order to obtain a notification about them under this section.

If the Commissioners consider that the particulars, or any further information provided under this subsection, are insufficient for the purposes of this section, they must notify the person what further information they require for those purposes within 30 days of receiving the particulars or further information.

If any such further information is not provided within 30 days from the notification, or such further time as the Commissioners allow, they need not proceed further under this section.

The Commissioners must notify the person whether they are satisfied that the transaction or transactions, as described in the particulars, were or will be such that no counteraction notice ought to be served about the transaction or transactions.

The notification must be given within 30 days of receipt of the particulars, or, if subsection (2) applies, of all further information required.
