18(1)A person is not required to give a notice under section 7 of TMA 1970 merely by reference to a chargeable gain accruing on a disposal if—
(a)the person delivers a return under this Schedule in respect of the disposal, and
(b)the return is delivered before the end of the notification period within the meaning of that section.
(2)But sub-paragraph (1) does not apply if the amount of capital gains tax notionally chargeable on the person as at the filing date for the return (as determined in accordance with paragraph 7) is less than the amount of capital gains tax for which the person is liable for the tax year concerned.
19(1)The amendment provisions applicable to ordinary tax returns apply in relation to returns made by a person under this Schedule as they apply in relation to ordinary tax returns, but subject to the following limitations or other modifications.

(3)A person may not make an amendment of a return under this Schedule in respect of a disposal at any time on or after—
(a)the date on which the person has delivered to an officer of Revenue and Customs the person’s ordinary tax return containing a self-assessment that takes account of the disposal, or
(b)the date on or before which the person has (by notice) been required to deliver to an officer of Revenue and Customs the person’s ordinary tax return for the tax year concerned.

(a)a notice of enquiry (“the main enquiry notice”) is given at any time into an ordinary tax return for a tax year, and
(b)a notice of enquiry into a return under this Schedule has not been given, on or before that time, in respect of a disposal to which this Schedule applies which is made in that tax year,
the main enquiry notice is also taken to constitute a notice of enquiry into the return under this Schedule in respect of the disposal.
(6)If—
(a)a final closure notice (“the main closure notice”) is given at any time which completes an enquiry into an ordinary tax return for a tax year, and

(b)any reference to the filing date is to be read as a reference to the filing date within the meaning of this Part of this Schedule (but see paragraph (e)),
(c)any reference to the amounts to be determined is to be read as a reference to the amount of capital gains tax which is notionally chargeable on a person as at the filing date for a return under this Schedule,
(d)any reference in any enactment to the purposes for which a determination is to have effect is to be ignored, and
(e)the determination may not be made after the end of the period of 3 years beginning with the last day for delivery of an ordinary tax return.

(a)a determination is made as a result of this paragraph, but
