the required return is not delivered on or before the filing date,

an officer of the Board may make a determination of the amounts in which, to the best of his information and belief, the person who should have made the return is chargeable to income tax and capital gains tax for the year of assessment or (as the case may be) is chargeable to corporation tax for the accounting period.

(2)

Notice of any determination under this section shall be served on the person in respect of whom it is made and shall state the date on which it is issued.

Until such time (if any) as it is superseded by a self-assessment made under section 9 or 11AA of this Act (whether by the taxpayer or an officer of the Board) on the basis of information contained in a return under the relevant section, a determination under this section shall have effect for the purposes of Parts VA, VI, IX and XI of this Act as if it were such a self-assessment.

(4)

Where—

(a)

an officer of the Board has commenced any proceedings for the recovery of any tax charged by a determination under this section; and

(b)

before those proceedings are concluded, the determination is superseded by such a self-assessment as is mentioned in subsection (3) above,

those proceedings may be continued as if they were proceedings for the recovery of so much of the tax charged by the self-assessment as is due and payable and has not been paid.

(5)

No determination under this section, and no self-assessment superseding such a determination, shall be made otherwise than—

(a)

in the case of such a self-assessment, before the end of the period of twelve months beginning with the date of the determination.
