All the provisions of the Corporation Tax Acts as to the time within which an assessment may be made, so far as they refer or relate to the accounting period for which an assessment is made, or the accounting period to which an assessment relates, shall apply in relation to an assessment under this Schedule notwithstanding that, under this Schedule, the assessment may be said to relate to a quarter or other period which is not an accounting period; and the provisions of sections 36 and 39 of the Management Act as to the circumstances in which an assessment may be made out of time shall apply accordingly on the footing that any such assessment relates to the accounting period in which the quarter or other period ends or, in the case of an assessment under paragraph 9 above, to an accounting period ending on the date on which the distribution is made.

Advance corporation tax assessed on a company under this Schedule shall be due within 14 days after the issue of the notice of assessment (unless due earlier under paragraph 3(1) or 9 above).

Sub-paragraph (2) above has effect subject to any appeal against the assessment, but no such appeal shall affect the date when tax is due under paragraph 3(1) or 9 above.

On the determination of an appeal against an assessment under this Schedule any tax overpaid shall be repaid.

Any tax assessable under any one or more of the provisions of this Schedule may be included in one assessment if the tax so included is all due on the same date.
