In sub-paragraph (1) above “the permitted period” means the period of thirty days beginning with the day on which the property ceases to be relevant property except in a case where it does so on the death of any person, and in such a case means the period of two years beginning with that day.

Sub-paragraph (1) above shall not apply if the individual has acquired the property concerned for a consideration in money or money’s worth; and for the purposes of this sub-paragraph an individual shall be treated as acquiring any property for such consideration if he becomes entitled to it as a result of transactions which include a disposition for such consideration (whether to him or another) of that or other property.

If the amount on which tax would be charged apart from sub-paragraph (1) above in respect of any property exceeds the value of the property immediately after the transfer there referred to (less the amount of any consideration for its transfer received by the individual), that sub-paragraph shall not apply but the amount on which tax is charged shall be equal to the excess.
