(4)The officer may, during the review period, issue to the company an amending notice which amends the charging notice so as to—

(8)The officer may, during the review period, issue a notice (a “supplementary charging notice”) to the company imposing an additional charge to diverted profits tax on the company in respect of the accounting period on taxable diverted profits which—
(a)arise to the company for that period, and
(b)are not already the subject of a charge to diverted profits tax.

(10)No supplementary charging notice may be issued during the last 30 days of the review period.
(11)Subsections (3) to (6) (amending notices) apply in relation to a supplementary charging notice as they apply to the charging notice.
(12)Section 95(5) (content of charging notice) and section 98 (payment of tax) apply in relation to a supplementary charging notice as they apply in relation to a charging notice.

(14)When determining on a review whether the total amount of taxable diverted profits charged on the company for an accounting period is excessive or insufficient—

(b)nothing in section 94 applies to restrict the representations which the officer may consider.
(15)Where a supplementary charging notice or an amending notice is issued to a company, the officer must give a copy of the notice—
